Delay taking up cannabis use until later in life
Identify and choose lower-risk cannabis products
Don’t use synthetic cannabinoids
Avoid smoking burnt cannabis—choose safer ways of using
If you smoke cannabis, avoid harmful smoking practices
Limit and reduce how often you use cannabis
Don’t use and drive, or operate other machinery

Health risks of cannabis use
There is strong scientific evidence that cannabis use is associated with a variety of health risks. The risks depend on your constitution, which kinds of cannabis products you use and how or how often you use them. Some of the main health risks are:
problems with thinking, memory or physical co-ordination
impaired perceptions or hallucinations
fatal and non-fatal injuries, including those from motor-vehicle accidents, due to impairment
Joint Statement on Scopes of Practice (February 2003)
Canada's physicians, nurses, pharmacists and other health professionals recognize that a sustainable health workforce is a key challenge facing our health care system. In this regard, scopes of practice is an important issue that needs to be addressed.
The Canadian Medical Association (CMA), the Canadian Nurses Association (CNA) and the Canadian Pharmacists Association (CPhA) have approved the following principles and criteria for the determination of scopes of practice. The primary purposes of such determinations are to meet the health care needs of Canadians, and to serve the interests of patients and the public safely, efficiently and competently.
The CPhA, CNA and CMA believe that policy decisions taken in this area must put patients first. Secondly, they should be grounded in principles that reflect our commitment to professionalism, lifelong learning and patient safety. Thirdly, that there be recognition of the need for legislative and regulatory changes to support evolving scopes of practice. Moreover, we believe that health professionals must be involved in decision-making processes in this area.
Focus: Scopes of practice statements should promote safe, ethical, high-quality care that responds to the needs of patients and the public in a timely manner, is affordable and is provided by competent health care providers.
Flexibility: A flexible approach is required that enables providers to practise to the extent of their education, training, skills, knowledge, experience, competence and judgment while being responsive to the needs of patients and the public.
Collaboration and cooperation: In order to support interdisciplinary approaches to patient care and good health outcomes, physicians, nurses and pharmacists engage in collaborative and cooperative practice with other health care providers who are qualified and appropriately trained and who use, wherever possible, an evidence-based approach. Good communication is essential to collaboration and cooperation.
Coordination: A qualified health care provider should coordinate individual patient care.
Patient choice: Scopes of practice should take into account patients' choice of health care provider.
Accountability: Scopes of practice should reflect the degree of accountability, responsibility and authority that the health care provider assumes for the outcome of his or her practice.
Education: Scopes of practice should reflect the breadth, depth and relevance of the training and education of the health care provider. This includes consideration of the extent of the accredited or approved educational program(s), certification of the provider and maintenance of competency.
Competencies and practice standards: Scopes of practice should reflect the degree of knowledge, values, attitudes and skills (i.e., clinical expertise and judgement, critical thinking, analysis, problem solving, decision making, leadership) of the provider group.
Quality assurance and improvement: Scopes of practice should reflect measures of quality assurance and improvement that have been implemented for the protection of patients and the public.
Risk assessment: Scopes of practice should take into consideration risk to patients.
Evidence-based practices: Scopes of practice should reflect the degree to which the provider group practices are based on valid scientific evidence where available.
Setting and culture: Scopes of practice should be sensitive to the place, context and culture in which the practice occurs.
Legal liability and insurance: Scopes of practice should reflect case law and the legal liability assumed by the health care provider including mutual professional malpractice protection or liability insurance coverage.
Regulation: Scopes of practice should reflect the legislative and regulatory authority, where applicable, of the health care provider.
Principles and criteria to ensure safe, competent and ethical patient care should guide the development of scopes of practice of health care providers.
This document is based on a January 2002 policy developed by the Canadian Medical Association whicb has been endorsed by the Canadian Nurses Association and the Canadian Pharmacists Association. We welcome the support of other health care providers for these principles and criteria regarding scopes of practice.
Dear Premier Ford and Minister Elliott:
We write to you as organizations concerned about the health and welfare of some of the most vulnerable Ontarians, following reports that your government plans to undertake an unnecessary review of the evidence on supervised consumption sites (SCS),1 and the even more troubling announcement that you are imposing a moratorium on the approval of new overdose prevention sites (OPS).2
All the available evidence, including substantial peer-reviewed scientific literature, demonstrates conclusively that these health services save lives and promote the health of people who use drugs. This includes opening doors to treatment. Rather than conduct an unnecessary review and delay expansion of these services, the Ontario government should work with community organizations and health providers to rapidly scale up these services. Delays mean more preventable overdose deaths and new infections of HIV, hepatitis C and other illnesses that could be averted.
Multiple reviews of the evidence have already been done, and have established that SCS and OPS:
provide a needed health service, reducing overdose deaths and the sharing of drug-injection equipment (and the associated risk of transmission of blood-borne infections);
increase access to addiction treatment and other necessary health services; and
benefit public order by reducing public injecting.3
As you know, Canada is experiencing a large-scale opioid overdose crisis. In Ontario alone, overdose deaths related to opioids increased by 45 per cent in 2017, with more than three people dying every day during that year.4 The opioid overdose epidemic has been called “the worst drug safety crisis in Canadian history.”5 HIV, hepatitis C and other infections, as well as overdose deaths, are preventable if the right measures are taken. These include increasing voluntary access to treatment for problematic drug use (where Ontario must do better), and also simultaneously scaling up evidence-based harm reduction services such as SCS and OPS.
We urge you to heed the recommendations of experts in public health, front-line clinicians, harm reduction staff, and people with lived experience of drug use. Rather than impeding access to life-saving health services, we urge you to work with community organizations and other health services providers to ensure greater, equitable access to SCS and OPS for the people of Ontario.
