The Dos

• DO bring your passport — It's the gold-standard ID accepted at every retailer
• DO check provincial rules at your destination — legal age, consumption, and retail models vary dramatically
• DO buy from licensed retailers only — Look for the federal excise stamp on all products as proof of legality
• DO start low with edibles — 2.5 to 5mg for newcomers, wait at least 2 hours before consuming more
• DO use taxis or rideshares after consuming cannabis
• DO store cannabis in sealed packaging when transporting in a vehicle
• DO dispose of all cannabis products before approaching any international border
• DO book cannabis-friendly accommodations in advance using BudandBreakfast.com or "420-friendly" Airbnb listings

The Don'ts

• DON'T cross any international border with cannabis — This is the most important rule. It's a federal crime in both directions.
• DON'T drive after consuming — Canada has specific THC blood limits with mandatory jail time for repeat offenders
• DON'T consume in any vehicle — Moving or parked, driver or passenger, it's illegal everywhere in Canada
• DON'T assume rules are the same everywhere — BC lets you smoke where tobacco is allowed; Quebec bans all public consumption
• DON'T smoke in hotel rooms unless explicitly permitted — Cleaning fees run $200–$500
• DON'T smoke near children, hospitals, or schools — Buffer zones apply in all provinces
• DON'T volunteer cannabis use to US border officers — But also never lie if asked directly
• DON'T assume CBD is exempt from border rules — All cannabis products are prohibited at international borders

Safety & Etiquette

• Start low, go slow — Canadian edibles are capped at 10mg THC per package, but even 5mg can be strong for newcomers
• Respect non-consumers — Avoid smoking near people who haven't consented to exposure
• Store securely — Keep cannabis in child-resistant packaging, especially around children
• Know your tolerance — Altitude, travel fatigue, and unfamiliar strains can amplify effects

Common Mistakes

1. Forgetting the age difference — You're legal at 19 in Ontario but under-age in Quebec (21)
2. Thinking "legal in Canada" means OK at the border — It absolutely does not
3. Not checking municipal rules — Calgary bans all public cannabis in a province (Alberta) with permissive state rules
4. Overconsumption of edibles — Effects take 30 minutes to 2 hours to appear; don't re-dose too soon
5. Ignoring travel insurance limits — Most policies exclude incidents while under cannabis influence
