Avoid frequent cannabis use
Reducing recreational cannabis use lowers exposure to dependence and lung harms.
The number, drawn
Occasional use, such as 1 day weekly or less, is lower risk
Why it matters
Frequent cannabis use increases the risk of losing control over use, and smoking it can damage lung tissue. Canadian public health guidance says occasional use, one day a week or less, is better than regular use. Not using at all offers the lowest risk, and a less frequent schedule is not a guarantee of safety.
How to do it
- If you do not use cannabis, there is no health reason to start recreational use.
- If you do use it, move away from daily use toward less frequent occasions.
- Avoid smoking cannabis and avoid products high in THC.
- Avoid cannabis during pregnancy, and seek support if reducing use is difficult.
Discuss prescribed cannabis with its prescriber before changing treatment; seek professional help for dependence or withdrawal.
Do it
Pick the time you have. Anything beats nothing.
Start with the time you have
1 minute
Count the days you used recreational cannabis in the past week. Notice whether use has become daily or hard to control.
5 minutes
Note recent use and trouble cutting back; contact your clinician about withdrawal or prescribed cannabis before changing it.
15 minutes
Identify a regular recreational use occasion and plan an alternative activity; ask for support if reducing is difficult and do not drive while impaired.
A plan
Move away from frequent recreational use
- Stage 1: Record your pattern; get help for withdrawal and discuss prescribed cannabis with its prescriber.
- Stage 2: Replace one regular use occasion with another activity and plan sober transport whenever needed.
- Stage 3: Review use weekly and keep reducing exposure with support; occasional use is not risk free.
In real life
- If you use recreationally, plan social time that does not center on cannabis.
- If use is hard to control, ask a health professional for support.
- After using cannabis, arrange transport with a sober driver instead of driving yourself.
Watch out for
- Common mistakeDo not treat a weekly limit as safe: avoiding recreational use has the lowest risk.
- Common mistakeDo not count hours to decide you are fit to drive: Health Canada says effects can last up to 12 hours after edibles, some up to 24. If you have used, get a lift.
- Common mistakeDo not change prescribed cannabis on your own: discuss treatment with its prescriber.
