Quebec Cannabis Laws for Adults and Visitors: Age, Limits and Retail
Educational summary, not legal advice. Check the current Quebec statute and official guidance before relying on a rule.
Quebec's adult-use rules at a glance
Quebec has stricter adult-use rules than many Canadian provinces. Do not apply another province's age, home-growing or retail rules here. The summary below covers selected points only.
Age and two different possession limits
Quebec prohibits possession by people under 21. For adults 21 and over, the public-place limit is 30 g of dried cannabis or equivalent. A 150 g dried-equivalent cap applies in a private residence regardless of how many adults 21+ live there. The same 150 g total also applies across a person's non-public places, including all residences; it is not a separate allowance for each home or each adult.
Home growing, public use and retail
Quebec prohibits personal cultivation and possession of cannabis plants. Only the Société québécoise du cannabis (SQDC) is authorized for retail cannabis sales. Quebec also prohibits smoking or vaping cannabis in indoor or outdoor spaces open to the public, including public roads; specific statutory place rules and exceptions require checking the law.
See our Canada province age guide for comparison, not as a substitute for Quebec's rules.
Visitors: federal and local questions remain separate
A provincial purchase or possession rule does not authorize international border crossing. Federal rules govern cross-border cannabis, while Quebec law controls relevant in-province conduct. Medical cannabis generally follows federal regulations, subject to Quebec's statutory restricted-use chapter; this page is not a medical-access guide.

Can adults grow a plant at home?
No. Quebec prohibits personal cultivation and possession of a cannabis plant.
