Since October 17, 2018, adults in Canada have been able to legally possess, buy, and use cannabis under the federal Cannabis Act. But there’s one huge catch: crossing borders with cannabis is extremely risky. Read on or risk serious fines, denied entry, or even jail!

How Much Cannabis Can You Legally Possess in Canada? 🤔
- Adults (18+) can have up to 30 grams of dried cannabis in public.
- Non-dried products follow this weight equivalency system:
- 1 g dried = 5 g fresh cannabis
- 1 g dried = 15 g edibles
- Health Canada offers an online calculator to track your limits.
Can You Grow Cannabis at Home? 🌱
Yes! Adults can grow up to 4 plants per residence for personal use, using licensed seeds or seedlings.
Buying Cannabis Legally 🛒
- Purchase from provincially-licensed retailers
- Or online from federally licensed producers where retail stores are unavailable
- Edibles, concentrates, and topicals are legal under strict rules for packaging and potency
Medical vs Recreational Cannabis 💊 vs 🌿
- Medical cannabis requires authorization from a healthcare provider and allows unlimited home storage
- Recreational cannabis follows possession and age limits under federal and provincial law
Provincial & Territorial Variations 📍
- Minimum age: Ontario – 19, Quebec – 21

U.S. Border Rules: Why Crossing Is a Nightmare 🚫🇺🇸
Even a tiny amount of cannabis or CBD can cause serious problems at U.S. ports of entry:
- Confiscation: Cannabis seized by CBP officers
- Monetary fines: Thousands of dollars
- Denied entry: You may be refused entry into the U.S.
- Lifetime ban: Possible permanent ban on visas and travel

Canadian Border Rules: Don’t Risk It Either 🇨🇦
Even returning to Canada with cannabis is illegal without a permit:

- Criminal prosecution: Depending on severity, charges may apply
- Imprisonment: Court fines or jail possible
Factors That Influence Penalties:
