Authorizing Cannabis for Medical Purposes The legalization of cannabis for recreational purposes came into effect with the Cannabis Act in October 2018, and patients continue to have access to cannabis for therapeutic purposes. The Cannabis Regulations have replaced the Access to Cannabis for Medical Purposes Regulations. Patients can obtain cannabis for medical purposes when a physician or nurse practitioner provides a “medical document” , authorizing its use, and determining the daily dried cannabis dose in grams. With the authorization, patients have the choice whether to (a) buy directly from a federally licensed producer; (b) register with Health Canada to produce a limited amount for personal consumption; (c) designate someone to produce it for them; or (d) buy cannabis at provincial or territorial authorized retail outlets or online sales platforms, if above the legal age limit. While acknowledging the unique requirements of patients suffering from a terminal illness or chronic disease for which conventional therapies have not been effective and for whom cannabis may provide relief, physicians remain concerned about the serious lack of clinical research, guidance and regulatory oversight for cannabis as a medical treatment. There is insufficient clinical information on safety and efficacy for most therapeutic claims. There is little information around therapeutic and toxic dosages and knowledge on interactions with medications. Besides the need for appropriate research, health practitioners would benefit from unbiased, accredited educational modules and decision support tools based on the best available evidence. The Canadian Medical Association has consistently expressed concern with the role of gatekeeper that physicians have been asked to take as a result of court decisions. Physicians should not feel obligated to authorize cannabis for medical purposes. Physicians who choose to authorize cannabis for their patients must comply with their provincial or territorial regulatory College's relevant guideline or policy. They should also be familiar with regulations and guidance, particularly:
Health Canada’s Information for Health Care Practitioners – Medical Use of Cannabis (monograph, summary and daily dose fact sheet),
the Canadian Medical Protective Association’s guidance;
the College of Family Physicians of Canada’s preliminary guidance Authorizing Dried Cannabis for Chronic Pain or Anxiety; and
the Simplified guideline for prescribing medical cannabinoids in primary care, published in the Canadian Family Physician. The CMA recommends that physicians should:
Ensure that there is no conflict of interest, such as direct or indirect economic interest in a licensed cannabis producer or be involved in dispensing cannabis;
Treat the authorization as an insured service, similar to a prescription, and not charge patients or the licensed producer for this service;
Until such time as there is compelling evidence of its efficacy and safety for specific indications, consider authorizing cannabis only after conventional therapies are proven ineffective in treating patients’ conditions;
Have the necessary clinical knowledge to authorize cannabis for medical purposes;
Only authorize in the context of an established patient-physician relationship;
Assess the patient’s medical history, conduct a physical examination and assess for the risk of addiction and diversion, using available clinical support tools and tests;
Engage in a consent discussion with patients which includes information about the known benefits and adverse health effects of cannabis in its various forms (e.g., edibles), including the risk of impairment to activities such as driving and work;
Advise the patient regarding harm reduction strategies and the prevention of accidental exposure for children and other people;
Document all consent discussions in patients' medical records;
Reassess the patient on a regular basis for its effectiveness to address the medical condition for which cannabis was authorized, as well as for addiction and diversion, to support maintenance, adjustment or discontinuation of treatment; and
Record the authorization of cannabis for medical purposes similar to when prescribing a controlled medication. The Cannabis Regulations provide some consistency with many established provincial and territorial prescription monitoring programs for controlled substances. Licensed producers of cannabis for medical purposes are required to provide information to provincial and territorial medical licensing bodies upon request, including healthcare practitioner information, daily quantity of dried cannabis supported, period of use, date of document and basic patient information. The Minister of Health can also report physicians to their College should there be reasonable grounds that there has been a contravention of the Narcotic Control Regulations or the Cannabis Regulations.

The Canadian Medical Association (CMA) is pleased to provide this submission in response to Health Canada’s consultation on new and innovative ideas on how to further strengthen the federal government’s health-focussed approach to substance use issues through the Canadian Drugs and Substances Strategy (CDSS) Question 1 What sorts of circumstances do you see within your networks, communities or in society that you think contribute to problematic substance use? There are multiple factors that contribute to problematic substance use. It is a serious, chronic and relapsing medical condition for which there are effective treatments. However, using the social determinants as a framework, most health promotion and prevention efforts will take place outside of the traditional health and medical care services. . Many Canadians face barriers in their physical, social and economic environments which can contribute to problematic substance use, and certain populations are at higher risk given these circumstances. For example, early childhood is a critical time in the social, emotional, cognitive and physical development of a person. Experiences in early life can ‘get under the skin’, changing the ways that genes are expressed. Negative experiences such as poverty or family or parental violence can have significant impacts on this important period of development. What is necessary is a coordinated effort across government sectors to ensure that all policy decisions serve to increase opportunities for health. Improving population health and reducing inequities should be an overall objective for all governments in Canada. Question 2 Have you seen or experienced programs, practices or models at the local or regional level that could be expanded, or implemented more broadly, to improve circumstances or social determinants of health that influence substance use? Income is critical to individual health and is closely linked to many of the other social determinants of health. These include but are not limited to: education, employment, early childhood development, housing, social exclusion, and physical environment. Adequate consideration must be given to the social and economic determinants of health, factors such as income and housing that have a major impact on health outcomes. Minimizing poverty should be a top priority. In 2015, the CMA passed a resolution endorsing the concept of a basic income guarantee, which is a cash transfer from government to citizens not tied to labour market participation. It ensures sufficient income to meet basic needs and live with dignity, regardless of employment status. A basic income guarantee has the potential to alleviate or even eliminate poverty. It has the potential to reduce the substantial, long-term social consequences of poverty, including higher crime rates and fewer students achieving success in the educational system. Drug use must not be treated with a criminal justice approach, which does not address the determinants of drug use, treat addictions, or reduce the harms associated with drug use. More investments need to be made in prevention, harm reduction and treatment, keeping individuals out of the criminal justice system. Drug use is a complex issue, and collaboration among health and public safety professionals, and society at large, is essential. Question 3 What needs to change to make sure that opioid medications are being provided and used appropriately, based on the needs of each patient? Policy makers must recognize that prescription opioids are an essential tool in the alleviation of pain and suffering, particularly in palliative and cancer care. Doctors support patients in the management of acute and chronic pain, as well as problematic substance use, and as such have long been concerned about the harms associated with opioid use. Treatment options and services for both problematic substance use as well as pain management are woefully under-resourced in Canada. Experts believe that improved access to specialized pain treatment could reduce inappropriate use of pain medications. Current best practices in pain management include care by an interprofessional team that could include physiotherapists, occupational therapists, psychologists and other health professionals; non-pharmaceutical interventions such as therapy for trauma and social pain, social supports and coping strategies; appropriate pharmaceutical prescription options, covered by provincial formularies; and a focus on patient participation and empowerment.12 Availability and access of these critical resources varies by jurisdiction and region. The federal government should prioritize the expansion of these services. It is also important to support clinicians in their practice. The 2017 Opioid Prescribing Guidelines need to be kept current through ongoing funding. Physicians require tools, including those that facilitate monitoring of effectiveness and tolerance by tracking pain and physical function; screening for past and current substance use; screening for depression; and, tapering of problematic or ineffective doses. Question 4 How can we make sure that those who require prescription opioids to manage their pain have access to them, without judgement or discrimination? Governments need to incorporate the identification and elimination of stigma as a quality of care indicator in the ongoing monitoring of health system performance at all levels. They also need to implement and evaluate national public awareness and education strategies to counteract the stigma associated with substance use issues as well as enforcing legislation and regulations to guard against discrimination against people with mental and substance use issues. Health professionals need to have access to education on pain management and treatment of problematic substance use, recognizing both issues as serious medical conditions for which there are effective treatments. Question 5 Which kinds of messages would work best to help Canadians understand the serious harms that can result from stigma around substance use? A recent report from the Canadian Centre on Substance Use and Addiction (CCSA) and Public Safety Canada cited stigma as “an enormous barrier to individuals seeking and maintaining treatment.” Even though there is broad recognition that we are in a public health crisis, until very recently the focus of the federal National Anti-Drug Strategy was heavily skewed towards a criminal justice approach rather than a public health approach with an emphasis on enforcement, as opposed to prevention, treatment and harm reduction.8 This has serious implications in how society views people who use drugs. As noted in the CCSA-Public Safety report, “Language matters. Speak about people first, with compassion and respect.”13 A stigma reduction strategy must be core to the activities of the federal government. Stigma involves thoughts, emotions and behaviours; thus, a comprehensive approach includes interventions to target each of these dimensions at both the individual and population level. The strategy should include aspects of: * Public awareness and education to facilitate understanding about the importance of early diagnosis, treatment, recovery and prevention; * Enhanced provider/student education and support; * Policy analysis and modification of discriminatory legislation; * Support for a strong voluntary sector to voice the concerns of patients and their families; * Exposure to positive spokespeople (e.g. prominent Canadians) who have mental illness and/or addiction in order to highlight success stories; * Researching stigma. Question 6 How can we best act to reduce stigma across the country? Engagement with people who use drugs to help them share their stories and experiences with stigma with the public Question 7 What would you recommend to improve substance use treatment services in Canada? This challenge requires a complex and multifaceted solution; and to further this aim, Canada needs a comprehensive national strategy to address the harms associated with psychoactive drugs in Canada, whether illegal or prescription-based, complementing existing strategies to address the harms associated with the other two legal drugs - alcohol and tobacco. This comprehensive approach is necessary, as isolated measures can have unintended consequences, such as under-medicating people that require a medical treatment or constraining people to seek illegal drugs as an option when medications are made tamper-resistant. One of the fundamental principles of health care is that it be patient centred.11 CMA defines patient-centred care as “seamless access to the continuum of care in a timely manner … that takes into consideration the individual needs and preferences of the patient and his/her family and treats the patient with respect and dignity.” It is essential that patients be core members of the health care team, working with health care providers to address their individual needs, preferences and aspirations and to seek their personal paths to well-being. Physicians and other health professionals can help patients make choices about their treatment and can provide information and support to patients and their families as they seek to cope with the effects of problematic use and live functional lives. The health care provider community needs tools to assist in the reduction of stigma, access to resources and supportive environments. Question 8 What obstacles or barriers do people face when they want to access treatment in Canada? Obstacles to treatment include the lack of publicly-funded treatment centres, access to locations for remote areas, limited number of beds available, the cost of private treatment (lack of insurance), and stigma. The CMA supports the enhancement of access to options for treatment that address different needs.12 Treatment programs must be coordinated and patient-centred, and address physical, psychological, social and spiritual circumstances. For example, it is important that treatment programs be culturally relevant for Indigenous communities. Question 10 In addition to current harm reduction initiatives – such as supervised consumption sites, needle exchange programs – what other harm reduction services should governments consider implementing in Canada? There is a dire need to address harm reduction in prisons. Even back in 2005, the CMA recommended to the Correctional Service of Canada that it develop, implement and evaluate a pilot needle exchange program in prison(s) under its jurisdiction. These services are not widespread and accessible to prison populations. In Canada, people in prison face far greater risk of HIV and hepatitis C infection because they are denied access to sterile injection equipment as a harm reduction strategy. Hospitals need to incorporate harm reduction strategies as well, allowing people who use drugs to access much needed health services. Question 12 How can we better bring public health and law enforcement together to explore ways to reduce the cycle of involvement for people who use substances with the criminal justice system? Training for police and other frontline criminal justice and corrections workers in how to interact with people with substance use issues is essential. The CMA believes that the government must take a broad public health policy approach. Changes to the criminal law affecting cannabis must not promote normalization of its use and must be tied to a national drug strategy that promotes awareness and prevention and provides for comprehensive treatment.13 The CMA recognized that a blanket prohibition of possession for teenagers and young adults would not reflect current reality or a harm reduction approach. The possibility that a young person might incur a lifelong criminal record for periodic use or possession of small amounts of cannabis for personal use means that the long-term social and economic harms of cannabis use can be disproportionate to the drug's physiological harm. Question 13 What further steps can the federal government take to better address current regulation and enforcement priorities, such as addressing organized drug crime and the dangerous illegal drugs like fentanyl being brought into Canada? The federal government must continue to work closely with the RCMP, local and provincial law enforcement agencies, Canada Post, the Canadian Border Services Agency, Crown attorneys, the Canadian military, and international health officials and law enforcement agencies to address this issue. This topic was covered in the recent CCSA/Public Safety Canada report.10 Question 14 Recognizing Indigenous rights and self-determination, how can all governments work together to address the high rates of problematic substance use faced by some Indigenous communities? Difficulties in access are particularly acute for Canada's Indigenous peoples. Many live in communities with limited access to health care services, sometimes having to travel hundreds of miles to access care. Additionally, there are jurisdictional challenges; many fall through the cracks between the provincial and federal health systems. While geography is a significant barrier for Indigenous peoples, it is not the only one. Indigenous peoples living in Canada's urban centres also face difficulties. Poverty, social exclusion and discrimination can be barriers to needed health care. Of all federal spending on indigenous programs and services only 10% is allocated to urban Aboriginals. This means that Aboriginals living in urban areas are unable to access programs such as Aboriginal head start, or alcohol and drug services, which would be available if they were living on reserve. Further, even when care is available it may not be culturally appropriate. Canada's indigenous peoples tend to be over-represented in populations most at risk and with the greatest need for care, making the lack of access a much greater issue for their health status. It is important that problematic substance use programs be culturally relevant for Indigenous communities. It is clear that the First Nations and Inuit peoples of Canada experience mental illness, problematic substance use and poor mental health at rates exceeding that of other Canadians.11 Individual, community and population level factors contribute to this including socioeconomic status, social environment, child development, nutrition, maternal health, culture and access to health services. The urgent need to work with these communities and identify the structures and interventions to reduce the burden of mental illness and substance use is critical to the health and wellness and future of First Nations and Inuit peoples. Enhanced federal capacity should be created through First Nations and Inuit Health that will provide increased funding and support for First Nations and Inuit community health strategies. The establishment of a working groups comprised of First Nations and Inuit health experts and accountable to First Nations and Inuit leadership is essential for the success of this initiative. Both expert and resource supports are integral elements to facilitate and encourage culturally appropriate strategies and programming in these communities. Question 15 What can we learn from Indigenous approaches to problematic substance use, such as using holistic approaches, that may help inform activities under the CDSS? The federal government must consult First Nations, Inuit, and Métis representatives to develop programs that are culturally relevant and appropriate for Indigenous communities. Question 16 How can governments, and the health, social, and law enforcement sectors design more effective substance use policies and programs for at-risk populations? The government must identify and consult those communities and populations most at risk. This includes First Nations, Inuit, and Métis representatives, community advocates, municipalities, and provincial and local public health officers. Data that describes rates of use and issues specific to each at risk group is important to be able to better understand and address needs. Question 17 What are effective policies and programs to help improve access to prevention, treatment, and harm reduction services for at-risk populations? There are innovative approaches to address the needs of high-volume users as well as at-risk populations. As many of these involve greater integration between health and the community sector and attention to issues not traditionally funded through health care payment systems, there is a need to provide access to funds to enable these innovations to continue and be spread across the country. A targeted, integrated approach to identify communities in need is required and this must be based on reliable community data (i.e., meaningful use of patient data) which can be used to integrate resources to improve health status. For example, the Canadian Primary Care Sentinel Surveillance Network (CPCSSN) is Canada's first multi-disease electronic medical records (EMR) surveillance and research system that allows family physicians, epidemiologists and researchers from across the country to better understand and manage chronic care conditions for their patients. Health information is collected from EMRs in the offices of participating primary care providers (e.g. family physicians) for the purposes of improving the quality of care for Canadians suffering from chronic and mental health conditions and three neurologic conditions including Alzheimer's and related dementias. CPCSSN makes it possible to securely collect and report on vital information from Canadians' health records to improve the way these chronic diseases and neurologic conditions are managed (http://cpcssn.ca/). Question 18 What urgent gaps related to substance use (in terms of data, surveillance, and/or research) need to be addressed in Canada? Improvements are being made in the collection of data in Canada. This is crucial to be able to assess the harms and track the trends and impact of the introduction of policy changes.12 As well, the government must continue to improve the ability of the Public Health Agency of Canada, the Canadian Institute of Health Information, the chief coroners of Canada and related agencies to collect, analyze and report data. One such program is the surveillance system in the United States called RADARS (Researched Abuse, Diversion and Addiction-Related Surveillance system) that is “a surveillance system that collects product-and geographically-specific data on abuse, misuse, and diversion of prescription drugs.” It surveys data involving opioids including poison control centres, treatment programs, on the “illicit acquisition or distribution of prescription opioids, stimulants, and other prescription drugs of interest from entities investigating drug diversion cases,” among other opioid-related issues. The CMA has recommended that all levels of government work with one another and with health professional regulatory agencies to develop a pan-Canadian system of real-time prescription monitoring. As a first step, the CMA recommends the establishment of consistent national standards for prescription monitoring. Prescription Monitoring Programs (PMP) should be compatible with existing electronic medical and pharmacy record systems and with provincial pharmaceutical databases. Participation in prescription monitoring programs should not impose an onerous administrative burden on health care providers. PMPs should not deter physicians from using controlled medications when necessary. Further, PMPs are a valuable component in addressing the gaps related to substance use. Question 19 How can we use research tools to better identify emerging substance use issues as early as possible? See above response to question 18 - “RADARS” Government of Canada.

The CMA is pleased to provide this submission to the Senate Standing Committee, Social Affairs, Science &Technology on Bill C-45, the Cannabis Act. The CMA has long-standing concerns about the health risks associated with consuming cannabis,i particularly in its smoked form.1,2 Children and youth are especially at risk for cannabis-related harms, given their brains are undergoing rapid and extensive development. The CMA's approach to cannabis is grounded in broad public health policy. It includes promotion of health and prevention of drug dependence and addiction; access to assessment, counselling and treatment services; and a harm reduction perspective. The CMA believes that harm reduction encompasses policies, goals, strategies and programs directed at decreasing adverse health, social and economic consequences of drug use for the individual, the community and the society while allowing the user to continue to use drugs, not precluding abstinence.3,4 Specifically, the CMA recommends a multi-faceted cannabis public health strategy that prioritizes impactful and realistic goals before, and certainly no later than, any legalization of cannabis.5 We propose that the first goal should be to develop educational interventions for children, teenagers and young adults. Other goals relate to data collection; monitoring and surveillance; ensuring a proportionate balance between enforcement harms and the direct and indirect harms caused by cannabis use; and research. There is an ongoing need for research into the medicinal and harmful effects of cannabis use. As noted by the Lower-Risk Cannabis Use Guidelines, 6 there is limited evidence on such subjects as synthetic cannabinoids; practices like "deep inhalation" to increase the psychoactive effects of cannabis; and the combination of risky behaviours, like early-onset and frequent use, associated with experiencing acute or chronic health problems.6 Since 2002, the CMA has taken a public health perspective regarding cannabis and other illegal drugs. More recently, the CMA endorsed the Lower-Risk Cannabis Use Guidelines, and we submitted 22 recommendations to the Task Force on Cannabis Legalization and Regulation ("the Task Force").7 Overview According to the recent Canadian Tobacco, Alcohol and Drugs Survey, cannabis is the most used illicit drug in Canada.8 In particular, 25%-30% of adolescents or youth report past-year cannabis use.9 This concerns the CMA. The increasing rate of high usage, despite the fact that non-medical use of cannabis is illegal, coupled with cannabis' increased potency (from 2% in 1980 to 20% in 2015 in the United States),10 the complexity and versatility of the cannabis plant,ii the variable quality of the end product, and variations in the frequency, age of initiation and method of use make it difficult to study the full health impacts and produce replicable, reliable scientific results. The CMA submits, therefore, that any legalization of cannabis for non-medical use must be guided by a comprehensive cannabis public health strategy and include a strong legal-regulatory framework emphasizing harm reduction principles. Given that the Task Force employed a minimizing of harms approach11 and given how the proposed legislation aligns with the Task Force's recommendations,12 the bill addresses several aspects of a legal-regulatory framework "to provide legal access to cannabis and to control and regulate its production, distribution and sale."13 This work provides the starting point for creating a national cannabis public health strategy. The CMA has long called for a comprehensive drug strategy that addresses addiction, prevention, treatment, enforcement and harm reduction.3 There are, however, key public health initiatives that the Canadian government has not adequately addressed and should be implemented before, or no later than, the implementation of legislation. One such initiative is education. Education is required to develop awareness among Canadians of the health, social and economic harms of cannabis use especially in young people. Supporting a Legal-Regulatory Framework that Advances Public Health and Protection of Children and Youth From a health perspective, allowing any use of cannabis by people under 25 years of age, and certainly those under 21 years of age, is challenging for physicians given the effects on the developing brain.1,3,14 The neurotoxic effect of cannabis, especially with persistent use, on the adolescent brain is more severe than on the adult brain.15,16 Further, neurological studies have shown that adolescent-onset cannabis use produces greater deficits in executive functioning and verbal IQ and greater impairment of learning and memory than adult-onset use.17,18 This underscores the importance of protecting the brain during development. Since current scientific evidence indicates that brain development is not completed until about 25 years of age,19 this would be the ideal minimum age for legal cannabis use. Youth and young adults are among the highest users of cannabis in Canada. Despite non-medical use of cannabis being illegal in Canada since 1923, usage has increased over the past few decades. The CMA recognizes that a blanket prohibition of possession for teenagers and young adults would not reflect current reality or a harm reduction approach.3 Harm reduction is not one of polarities rather it is about ensuring the quality and integrity of human life and acknowledging where the individual is at within his/her community and society at large.5 The possibility that a young person might incur a lifelong criminal record for periodic use or possession of small amounts of cannabis for personal use means that the long-term social and economic harms of cannabis use can be disproportionate to the drug's physiological harm. The Canadian government has recognized this disproportionality for over 15 years. Since 2001, there have been two parliamentary committee reportsiii and two billsiv introduced to decriminalize possession of small amounts of cannabis (30 g). It was recommended that small amounts of cannabis possession be a "ticketable" offence rather than a criminal one. Given all of the above, the CMA recommends that the age of legalization should be 21 years of age and that the quantities and the potency of cannabis be more restricted to those under age 25. Supporting a Comprehensive Cannabis Public Health Strategy with a Strong, Effective Education Component The CMA recognizes that Bill C-45 repeals the prohibition against simple possession while increasing penalties against the distribution and sale of cannabis to young people, but this is not enough to support a harm reduction approach. We note that the Federal Tobacco Control Strategy, with its $38 million budget, is intended to help reduce smoking rates and change Canadians' perceptions toward tobacco.20 Similarly, there are extensive education programs concerning the dangers of alcohol, particularly for young people.v The government of Canada has proposed a modest commitment of $9.6 million to a public awareness campaign to inform Canadians, especially youth, of the risks of cannabis consumption, and to surveillance activities.21 A harm reduction strategy should include a hierarchy of goals with an immediate focus on groups with pressing needs. The CMA submits that young people should be targeted first with education. The lifetime risk of dependence to cannabis is estimated at 9%, increasing to almost 17% in those who initiate use in adolescence.22 In 2012, about 1.3% of people aged 15 years and over met the criteria for cannabis abuse or dependence - double the rate for any other drug - because of the high prevalence of cannabis use.23 The strategy should include the development of educational interventions, including skills-based training programs, social marketing interventions and mass media campaigns. Education should focus not only on cannabis' general risks but also on its special risks for the young and its harmful effects on them. This is critical given that for many, the perception is that (i) legalization of possession for both adults and young people translates into normalization of use and (ii) government control over the source of cannabis for sale translates into safety of use. Complicating this has been the fear-mongering messaging associated with illegal drugs. The evidence shows that fewer adolescents today believe that cannabis use has any serious health risks24 and that enforcement policies have not been a deterrent.25 Having an appropriate education strategy rolled out before legalization of possession would reduce the numbers of uninformed young recreational users. It would also provide time to engage in meaningful research on the impact of the drug on youth. Such strategies have been successful in the past; for example, the long-termvi Federal Tobacco Control Strategy has been credited with helping reduce smoking rates to an all-time low in Canada.26 The Lower-Risk Cannabis Use Guidelines were developed as a "science-based information tool for cannabis users to modify their use toward reducing at least some of the health risks."6 The CMA urges the government to support the widespread dissemination of this tool and incorporation of its messages into educational efforts. Other strategies must include plain packaging and labelling with health information and health warnings. Supporting a One-System Approach. Alternatively, a Review of Legislation in Five Years The CMA believes that once the act is in force, there will be little need for two systems (i.e., one for medical and one for non-medical cannabis use). Cannabis will be available for those who wish to use it for medicinal purposes, either with or without medical authorization (some people may self-medicate with cannabis to alleviate symptoms but may be reluctant to raise the issue with their family physician for fear of being stigmatized), and for those who wish to use it for other purposes. The medical profession does not need to continue to be involved as a gatekeeper once cannabis is legal for all, especially given that cannabis has not undergone Health Canada's usual pharmaceutical regulatory approval process. The Task Force's discussion reflects the tension it heard between those who advocated for one system and those who did not. One concern raised by patients was about the stigma attached to entering retail outlets selling non-medical cannabis. The CMA submits that this concern would be alleviated if the federal government continued the online purchase and mail order system that is currently in place. Given that there is a lack of consensus and insufficient data to calculate how much of the demand for cannabis will be associated with medical authorization, the Task Force recommended that two systems be established, with an obligation to review - specifically, a program evaluation of the medical access framework in five years.11 If there are two systems, then in the alternative, the CMA recommends a review of the legislation within five years. This would allow time to ensure that the provisions of the act are meeting their intended purposes, as determined by research on the efficacy of educational efforts and other research. Five-year legislative reviews have been previously employed, especially where legislation must balance individual choice with protecting public health and public safety.vii For example, like Bill C-45, the purpose of the Controlled Drugs and Substances Act is to protect public health and public safety.27 Its review within five years is viewed as allowing for a thorough, evidence-based analysis to ensure that the provisions and operations of the act are meeting their intended purpose(s).viii Furthermore, a harm reduction approach lends itself to systematic evaluation of the approach's short- and long-term impact on the reduction of harms.5 The CMA, therefore, submits that if a two-system approach is implemented when the legislation is enacted, the legislation should be amended to include the requirement for evaluation within five years of enactment. Criteria for evaluation may include the number of users in the medical system and the number of physicians authorizing medical cannabis use. The CMA would expect to be involved in the determination of such criteria and evaluation process. Conclusion Support has risen steadily in Canada and internationally for the removal of criminal sanctions for simple cannabis possession, as well as for the legalization and regulation of cannabis' production, distribution and sale. The CMA has long-standing concerns about the health risks associated with consuming cannabis, especially by children and youth in its smoked form. Weighing societal trends against the health effects of cannabis, the CMA supports a broad legal-regulatory framework as part of a comprehensive and properly sequenced public health approach of harm reduction. Recommendations 1. The CMA recommends that the legalization age be amended to 21 years of age, to better protect the most vulnerable population, youth, from the developmental neurological harms associated with cannabis use. 2. The CMA recommends that a comprehensive cannabis public health strategy with a strong, effective health education component be implemented before, and no later than, the enactment of any legislation legalizing cannabis. 3a. The CMA recommends that there be only one regime for medical and non-medical use of cannabis, with provisions for the medical needs of those who would not be able to acquire cannabis in a legal manner (e.g., those below the minimum age). 3b. Alternatively, the CMA recommends that the legislation be amended to include a clause to review the legislation, including a review of having two regimes, within five years. i The term cannabis is used as in Bill C-45: that is, referring to the cannabis plant or any substance or mixture that contains any part of the plant. ii The plant contains at least 750 chemicals, of which there are over 100 different cannabinoids.

The Canadian Medical Association (CMA) is pleased to provide this submission to the House of Commons Standing Committee on Health for its study of Bill S-5, An Act to amend the Tobacco Act and the Non-Smokers Health Act and to make consequential amendments to other Acts. We support the government’s effort to implement a new legislative and regulatory framework to address vaping products and related matters. Vaping products, such as electronic cigarettes (or e-cigarettes) replicate the act and taste of smoking but do not contain tobacco. We also recognize that the federal government is attempting to find a balance between regulating vaping devices and making them available to adults. Canada’s physicians, who see the devastating effects of tobacco use every day in their practices, have been working for decades toward the goal of a smoke-free Canada. The CMA issued its first public warning concerning the hazards of tobacco in 1954 and has continued to advocate for the strongest possible measures to control its use. The CMA has always supported strong, comprehensive tobacco control legislation, enacted and enforced by all levels of government, and we continue to do so. Our most recent efforts centred on our participation in the 2016 Endgame Summit, held late last year in Kingston, Ontario. This brief will focus on three areas: supporting population health; the importance of protecting youth; and, the promotion of vaping products. Overview Tobacco is an addictive and hazardous product, and a leading cause of preventable disease and death in Canada. Smoking has been on the decline in Canada the most recent Canadian Community Health Survey reports that 17.7% of the population aged 12 and older were current daily or occasional smokers in 2015 (5.3 million smokers); that is down from 18.1% in 2014.1 Many strong laws and regulations have already been enacted but some areas remain to be addressed and strengthened especially as the 1 Statistics Canada.

J Adolesc Health. 2017 May;60(5):592–8. tobacco industry continues to evolve. Electronic cigarettes and vaping represents the next step in that evolution. While Canada is to be congratulated on its success to date, it needs to maintain an environment that encourages Canadians to remain tobacco-free if smoking prevalence is to be reduced further in Canada. The CMA believes it is incumbent on all levels of government in Canada to keep working on comprehensive, coordinated and effective tobacco control strategies, including vaping products, to achieve that goal. Supporting Population Health The arrival of vaping products in Canada placed them in a “grey zone” with respect to legislation and regulation. Clarification of their status is crucial from a public health perspective because of their growing popularity, particularly among youth.2 E-cigarettes have both defenders and opponents. Proponents say they are safer than tobacco cigarettes since they do not contain the tar and other toxic ingredients that are the cause of tobacco related disease. Indeed, some believe they serve a useful purpose as a harm reduction tool or cessation aid (though it is forbidden to market them as such since that claim has never been approved by Health Canada). Opponents are concerned that the nicotine delivered via e-cigarettes is addictive and that the cigarettes may contain other toxic ingredients such as nitrosamines. Also, they worry that acceptance of e-cigarettes will undermine efforts to de-normalize smoking, and that they may be a gateway to the use of tobacco by people who might otherwise have remained smoke-free. This issue will be addressed later in this brief. This difference of opinion certainly highlights the need for more research into the harms and benefits of vaping products and the factors that cause people to use them.3 Encouraging smokers to move from combustible tobacco products to a less harmful form of nicotine may be a positive step. However the current available evidence is not yet sufficient to establish them as a reliable cessation method. A systematic review published by M. Malas et al. (2016) concluded that while “a majority of studies demonstrate a positive relationship between e-cigarette use and smoking cessation, the evidence remains inconclusive due to the low quality of the research published to date.”4 Indeed, some are helped by these devices to quit smoking but “more carefully designed and scientifically sound studies are urgently needed to establish unequivocally the long-term cessation effects of e-cigarettes and to better understand how and when e-cigarettes may be helpful.”4 The authors found that the evidence examining e-cigarettes as an aid to quitting smoking was determined to be “very low to low.”4 A similar result was found for their use in reducing smoking; the quality of the evidence was revealed as being “very low to moderate.”4 This conclusion is supported by another review conducted by the University of Victoria (2017). It too indicates that there are not enough studies available to fully determine the efficacy of vaping devices as a tobacco cessation device.5 This review also noted that there is “encouraging evidence that vapour devices can be at least as effective as other nicotine replacements.”5 Another review by R. El Dib et al. (2017) reinforces these findings. Limited evidence was also found with respect to the impact of electronic devices to aide cessation. They also noted that the data available from randomized control trials are of “low certainty” and the “observational studies are of very low certainty.”6 The wide range of devices available makes it very difficult to test which are the most effective in helping cessation efforts. Many of the studies are on older devices so it is possible that as second-generation technology becomes available they will prove to be more successful. In view of this uncertainty, the CMA calls for more scientific research into the potential effectiveness and value of these devices as cessation aids. Physicians need to be confident that if they recommend such therapy to their patients it will have the desired outcome. To that end, we are pleased that Health Canada will continue to require manufacturers to apply for authorization under the Food and Drugs Act to sell products containing nicotine and make therapeutic claims. Risk and Safety In addition to the discussion concerning the usefulness of vaping devices as cessation devices, concerns from a public health standpoint involve the aerosol or vapour produced by heating the liquids used in these devices, and the nicotine some may contain. The tube of an e-cigarette contains heat-producing batteries and a chamber holding liquid. When heated, the liquid is turned into vapour which is drawn into the lungs. Ingredients vary by brand but many contain nicotine and/or flavourings that are intended to boost their appeal to young people. The CMA is concerned that not enough is known about the safety of the ingredients in the liquids being used in vaping devices. While it is the case that because e-cigarettes heat rather than burn the key constituent, they produce less harmful toxins and are much safer than conventional cigarettes. Research in the UK suggested that “long-term Nicotine Replacement Therapy (NRT)-only and e-cigarette-only use, but not dual-use of NRTs or e-cigarettes with combustible cigarettes, is associated with substantially reduced levels of measured carcinogens and toxins relative to smoking only combustible cigarettes.”7 However, this study has been criticized because “it only looked at a few toxins and didn’t test for any toxins that could be produced by e- cigarettes.”8 The variety of flavourings and delivery systems available make it imperative that the risks associated with these products be fully understood. As one study noted “analysis of e-liquids and vapours emitted by e-cigarettes led to the identification of several compounds of concern due to their potentially harmful effects on users and passively exposed non-users.”9 The study found that the emissions were associated with both cancer and non-cancer health impacts and required further study.9 There is another aspect of the public health question surrounding vaping devices. There is data to support the idea that “nicotine exposure during periods of developmental vulnerability (e.g., fetal through adolescent stages) has multiple adverse health consequences, including impaired fetal brain and lung development.”10 Therefore it is imperative that pregnant women and youth be protected. There is not enough known about the effects of long-term exposure to the nicotine inhaled through vaping devices at this time.11 Recommendations: 1) Given the scarcity of research on e-cigarettes the Canadian Medical Association calls for ongoing research into the potential harms of electronic cigarette use, including the use of flavourings and nicotine. 2) The CMA calls for more scientific research into the potential effectiveness and value of these devices as cessation aids. 3) The Canadian Medical Association supports efforts to expand smoke-free policies to include a ban on the use of electronic cigarettes in areas where smoking is prohibited. Protecting Youth The CMA is encouraged by the government’s desire to protect youth from developing nicotine addiction and inducements to use tobacco products. Young people are particularly vulnerable to peer pressure, and to tobacco industry marketing tactics. The CMA supports continued health promotion and social marketing programs aimed at addressing the reasons why young people use tobacco and have been drawn to vaping devices, discouraging them from starting to use them and persuading them to quit, and raising their awareness of tobacco industry marketing tactics so that they can recognize and counteract them. These programs should be available continuously in schools and should begin in the earliest grades. The “cool/fun/new” factor that seems to have developed around vaping devices among youth make such programs all the more imperative.12 The CMA recommends a ban on the sale of all electronic cigarettes to Canadians younger than the minimum age for tobacco consumption in their province or territory. We are pleased to see that Bill S-5 aims to restrict access to youth, including prohibiting the sale of both tobacco and vaping products in vending machines as well as prohibiting sales of quantities that do not comply with the regulations. In fact, the CMA recommends tightening the licensing system to limit the number of outlets where tobacco products, including vaping devices, can be purchased. The more restricted is availability, the easier it is to regulate. The CMA considers prohibiting the promotion of flavours in vaping products that may appeal to youth, such as soft drinks and cannabis, to be a positive step. A recent report published by the World Health Organization and the US National Cancer Institute indicated that websites dedicated to retailing e-cigarettes “contain themes that may appeal to young people, including images or claims of modernity, enhanced social status or social activity, romance, and the use of e-cigarettes by celebrities.”13 We are therefore pleased that sales of vaping products via the internet will be restricted through prohibiting the sending and delivering of such products to someone under the age of 18. This will be critical to limiting the tobacco industry’s reach with respect to youth. There have also been arguments around whether vaping products will serve as gateways to the use of combusted tobacco products. The University of Victoria (2017) paper suggests this isn’t the case; it notes that “there is no evidence of any gateway effect whereby youth who experiment with vapour devices are, as a result, more likely to take up tobacco use.”5) They base this on the decline in youth smoking while rates of the use of vaping devices rise.Error! Bookmark not defined. Others contend that vaping is indeed a gateway, saying it acts as a “one-way bridge to cigarette smoking among youth. Vaping as a risk factor for future smoking is a strong, scientifically-based rationale for restricting access to e-cigarettes.”14 Further, in a “national sample of US adolescents and young adults, use of e-cigarettes at baseline was associated with progression to traditional cigarette smoking. These findings support regulations to limit sales and decrease the appeal of e- cigarettes to adolescents and young adults.”15 However, there may be a role for vaping products in relation to young users. A New Zealand study conducted among young adults that examined how electronic nicotine delivery systems (ENDS) were used to recreate or replace smoking habits. It found that study participants “used ENDS to construct rituals that recreated or replaced smoking attributes, and that varied in the emphasis given to device appearance.”16 Further, it was suggested that ascertaining how “ENDS users create new rituals and the components they privilege within these could help promote full transition from smoking to ENDS and identify those at greatest risk of dual use or relapse to cigarette smoking.”16 The CMA believes that further research is needed on the question of the use of vaping products as a gateway for youth into combustible tobacco products. Recommendations: 4) The Canadian Medical Association recommends a ban on the sale of all electronic cigarettes to Canadians younger than the minimum age for tobacco consumption in their province or territory. 5) The Canadian Medical Association calls for ongoing research into the potential harms and benefits of electronic cigarette use among youth. 6) The Canadian Medical Association recommends tightening the licensing system to limit the number of outlets where tobacco products, including vaping devices, can be purchased. Promotion of Vaping Products The CMA has been a leader in advocating for plain and standardized packaging for tobacco products for many years. We established our position in 1986 when we passed a resolution at our General Council in Vancouver recommending to the federal government “that all tobacco products be sold in plain packages of standard size with the words “this product is injurious to your health” printed in the same size lettering as the brand name, and that no extraneous information be printed on the package.” The CMA would like to see the proposed plain packing provisions for tobacco be extended to vaping products as well. The inclusion of the health warning messages on vaping products is a good first step but efforts should be made to ensure that they are of similar size and type as those on tobacco as soon as possible. The restrictions being applied to the promotion of vaping products is a positive step, especially those that could be aimed at youth, but they do not go far enough. The CMA believes the restrictions on promotion should be the same as those for tobacco products. As the WHO/U.S. National Cancer Institute has already demonstrated, e- cigarette retailers are very good at using social media to promote their products, relying on appeals to lifestyle changes to encourage the use of their products. The CMA is also concerned that e-cigarette advertising could appear in locations and on mediums popular with children and youth if they are not prohibited explicitly in the regulations. This would include television and radio advertisements during times and programs popular with children and youth, billboards near schools, hockey arenas, and on promotional products such as t-shirts and ball caps. As efforts continue to reduce the use of combustible tobacco products there is growing concern that the rising popularity of vaping products will lead to a “renormalization” of smoking. In fact, worry has been expressed that the manner they have been promoted “threaten(s) to reverse the successful, decades-long public health campaign to de- normalize smoking.”17 A recent US study indicated that students that use vaping products themselves, exposure to advertising of these devices, and living with other users of vaping products is “associated with acceptability of cigarette smoking, particularly among never smokers.”18 Further research is needed to explore these findings. Recommendations: 7) The Canadian Medical Association recommends similar plain packaging provisions proposed for tobacco be extended to vaping products. 8) Health warning messages on vaping products should be of similar size and type as those on tobacco as soon as possible 9) The Canadian Medical Association believes the restrictions on promotion of vaping products and devices should be the same as those for tobacco products. Conclusion Tobacco is an addictive and hazardous product, and a leading cause of preventable disease and death in Canada. Our members see the devastating effects of tobacco use every day in their practices and to that end the CMA has been working for decades toward the goal of a smoke-free Canada. The tobacco industry continues to evolve and vaping represents the next step in that evolution. The CMA believes it is incumbent on all levels of government in Canada to keep working on comprehensive, coordinated and effective tobacco control strategies, including vaping products, to achieve that goal. Bill S-5 is another step in that journey. Researchers have identified potential benefits as well as harms associated with these products that require much more scrutiny. The association of the tobacco industry with these products means that strong regulations, enforcement, and oversight are needed. Recommendations: 1) Given the scarcity of research on e-cigarettes the Canadian Medical Association calls for ongoing research into the potential harms of electronic cigarette use, including the use of flavourings and nicotine. 2) The CMA calls for more scientific research into the potential effectiveness and value of these devices as cessation aids.. 3) The Canadian Medical Association supports efforts to expand smoke-free policies to include a ban on the use of electronic cigarettes in areas where smoking is prohibited. 4) The Canadian Medical Association recommends a ban on the sale of all electronic cigarettes to Canadians younger than the minimum age for tobacco consumption in their province or territory. 5) The Canadian Medical Association calls for ongoing research into the potential harms and benefits of electronic cigarette use among youth. 6) The Canadian Medical Association recommends tightening the licensing system to limit the number of outlets where tobacco products, including vaping devices, can be purchased. 7) The Canadian Medical Association recommends similar plain packaging provisions proposed for tobacco be extended to vaping products. 8) Health warning messages on vaping products should be of similar size and type as those on tobacco as soon as possible 9) The Canadian Medical Association believes the restrictions on promotion of vaping products and devices should be the same as those for tobacco products.

The Canadian Medical Association appreciates this opportunity to respond to Health Canada's public consultation on the proposed regulatory approach for the proposed Cannabis Act, Bill C-45. Our approach to cannabis is grounded in broad public health policy. It includes promotion of health and prevention of drug dependence and addiction; access to assessment, counselling and treatment services; and a harm reduction perspective. The CMA endorsed the Lower-Risk Cannabis Use Guidelines1 and has expressed these views in our recommendations to the Task Force on Cannabis Legalization and Regulation,2 recommendations regarding Bill C-453 and submission on the cannabis excise duty framework.4 Therefore, we are limiting our response to those consultation questions that pertain to that approach and relate to our expertise and knowledge base. We are providing responses to questions 9, 10 and 11. Consultation questions Packaging and labelling 9. What do you think about the proposed rules for the packaging and labelling of cannabis products? Do you think additional information should be provided on the label? The CMA concurs with the proposed regulations. Packaging and labelling of cannabis products should include measures such as:
a requirement for plain and standard packaging,5 6
prohibition of the use of appealing flavours and shapes,
a requirement for adequate content and potency labelling,
a requirement for comprehensive health warnings,
a requirement for childproof packaging, and
a requirement that the content in a package should not be sufficient to cause an overdose. Education is required to develop awareness among Canadians of the health, social and economic harms of cannabis use especially in young people. In that regard, the regulations with respect to packaging and labelling should be viewed as an opportunity to maximize educational opportunities. Package inserts must outline and reinforce the health risks involved; they must also be designed by governments and health professionals, not cannabis producers or distributors. Package inserts should include:
information on securing the product in the home to prevent access by youth and children,
recommendations not to drive or to work with hazardous chemicals or operate equipment while using the contents of the package,
information on the health and social consequences (including legal penalties) of providing cannabis to those under a designated minimum age for purchasing, and
contact information for hotlines for poison control and for crisis support. In addition, the regulations for the marketing and advertising of cannabis should use an approach similar to those in place for tobacco and cigarettes.7 8 9 Cannabis for medicinal purposes 10. What do you think about the proposed approach to providing cannabis for medical purposes? Do you think there should be any specific additional changes? CMA maintains its position that there should be one system with one set of regulations for medical and recreational cannabis. The CMA believes that once the Act and regulations are in force, there will be no need for two systems. Cannabis will be available for those who wish to use it for medicinal purposes, either with or without medical authorization, and for those who wish to use it for other purposes. The medical profession does not need to authorize use once cannabis is legalized, especially given that cannabis has not undergone Health Canada's usual pharmaceutical regulatory approval process, and its anticipated removal as a controlled substance from the Controlled Drugs and Substances Act. Those who have experienced a two-system approach in Washington and Colorado have remarked on the challenges of having dual standards and regulations (e.g., purchase and possession quantities, taxation levelsa 4) and the contribution to the grey market.b 11 Consistent with the advice it received from the Task Force on Legalization and Regulation of Cannabis,12 the government intends on pursuing both a medicinal and retail cannabis system at this time. In this instance the CMA supports regulations for each system being as similar as possible. Furthermore, the CMA strongly supports the need for appropriate and relevant data collection (e.g., interaction of individuals between the medicinal and retail systems) to provide the necessary evidence for the future legislative review, anticipated in three years' time. The CMA would expect to be involved and looks forward to participating in the criteria development, evaluation and performance review of the systems. Sale of health products containing cannabis 11. What do you think about the proposed restrictions on the sale of health products containing cannabis authorized by Health Canada? Do they strike an appropriate balance between facilitating access to safe, effective and high quality health products, and deterring illegal activities and youth access? Health products include prescription health products, non-prescription drugs, natural health products, cosmetics and medical devices. Although all these products are regulated by Health Canada, they undergo different levels of scrutiny for safety, efficacy and quality, and in some cases industry does not need to provide scientific evidence to support the claims made on the label. The level of proof required to obtain a Drug Identification Number (DIN) for prescription drugs is considerably higher than the level of proof required for a Natural Product Number (NPN); rigorous scientific evidence is needed for a DIN but not for a NPN. Consumers generally do not know about this distinction, believing that Health Canada has applied the same level of scrutiny to the health claims made for every product. As a result, consumers presently do not have sufficient information to choose appropriate products. Health Canada launched a consultation in 201613 on the approval process of the categories of non-prescription drugs, natural health products and cosmetics ("self-care products") with the intent of modernizing the present regulations. The CMA fully supports this work and hopes it will be brought to a timely conclusion.14 With respect to all health products, the CMA supports a risk-based approach in which higher risk products, for example, those for which health claims are made, must meet a higher standard of review. Rigorous scientific evidence is needed to support claims of health benefits and to identify potential risks and adverse reactions. All health products containing cannabis must meet a high standard of review for safety, efficacy and quality, equivalent to that of the approval of prescription drugs (e.g., Marinol(r) and Sativex(r)), to protect Canadians from further misleading claims. Prescription drugs are subject to Health Canada's pharmaceutical regulatory approval process, based on each drug's specific indication, dose, route of administration and target population. Health claims need to be substantiated via a strong evidentiary process. With respect to the sale of cannabis products to youth, the CMA recommends the adoption of strict controls as outlined in the proposed regulations; as per the proposal, "All health products would be subject to provisions that control against practices that may appeal to youth, or the use of testimonials, real or fictional characters or animals, or lifestyle branding. Tamper-evident and child-resistant packaging requirements would also apply."15 We also support the additional precautions around medical devices, especially those sold to young persons. The CMA urges caution around the exemption for paediatric formulations that would allow for traits that would "appeal to youth." The CMA understands that these products, used under strict health professional supervision, should be child friendly, for example, regarding palatability, but we do not support marketing strategies that would suggest their use is recreational (e.g., producing them in candy or animal formats). There will be a need for careful monitoring of the health products released in the market and the health claims made. Experience has shown that regulations can and will be circumvented, and these activities will have to be addressed. Various examples have been reported in the media highlighting the need to be vigilant, as illustrated in Switzerland regarding health and other products with cannabis and high cannabidiol content.16 17 a The CMA supports similar taxation treatment of cannabis products for medical and non-medical purposes. b Grey market refers to products produced or distributed in ways that are unauthorized or unregulated, but not strictly illegal. 1 Fischer B, Russell C, Sabioni P, et al.
