Note: These Guidelines are not intended to encourage people who choose to abstain for cultural, spiritual or other reasons to drink, nor are they intended to encourage people to commence drinking to achieve health benefits. People of low bodyweight or who are not accustomed to alcohol are advised to consume below these maximum limits.
Do not drink in these situations:
When operating any kind of vehicle, tools or machinery; using medications or other drugs that interact with alcohol; engaging in sports or other potentially dangerous physical activities; working; making important decisions; if pregnant or planning to be pregnant; before breastfeeding; while responsible for the care or supervision of others; if suffering from serious physical illness,
mental illness or alcohol dependence.
If you drink, reduce long- term health risks by staying within these average levels:
0–2 standard drinks* per day
0–3 standard drinks* per day
No more than 10 standard drinks
No more than 15 standard
drinks per week
Always have some non-drinking days per week to minimize tolerance and habit formation. Do not increase drinking to the
upper limits as health benefits are greatest at up to one drink per day. Do not exceed the daily limits specified in Guideline 3.
If you drink, reduce short- term risks by choosing safe situations and restricting your alcohol intake:
Risk of injury increases with each additional drink in many situations. For both health and safety reasons, it is important not to drink more than:
Three standard drinks* in one day for a woman
Four standard drinks* in one day for a man
Drinking at these upper levels should only happen occasionally and always be consistent with the weekly limits specified in Guideline 2. It is especially important on these occasions to drink with meals and not on an empty stomach; to have no more than two standard drinks in any three-hour period; to alternate with caffeine-free, non-alcoholic drinks; and to avoid risky situations and activities. Individuals with reduced tolerance, whether due to
low bodyweight, being under the age of 25 or over 65 years old, are advised to never exceed Guideline 2 upper levels.
When pregnant or planning to be pregnant:
The safest option during pregnancy or when planning to become pregnant is to not drink alcohol at all. Alcohol in the mother's bloodstream can harm the developing fetus. While the risk from light consumption during pregnancy appears very low, there is no threshold of alcohol use in pregnancy that has been
definitively proven to be safe.
Alcohol and young people:
Alcohol can harm healthy physical and mental development of children and adolescents. Uptake of drinking by youth should be delayed at least until the late teens and be consistent with local legal drinking age laws. Once a decision to start drinking is made, drinking should occur in a safe environment, under parental guidance and at low levels (i.e., one or two standard drinks* once or twice per week). From legal drinking age to 24 years, it is
recommended women never exceed two drinks per day and men never exceed three drinks in one day.
