(CNN) — As laws surrounding recreational marijuana slowly change state by state in the United States, Canada as a country has just legalized the substance.
Adults 18 years and older can now purchase pot and and even grow it in their homes for personal use.
State laws vary in the United States but because US federal law is clear that marijuana is illegal, that means that even going from, say, Vancouver to Los Angeles International Airport (LAX), is risky. This is the case even though LAX recently announced that passengers are permitted to travel with small amounts of marijuana.
Plus, the legal age for recreational possession of marijuana in California is 21, adding to the murkiness — and danger — of traveling internationally with a substance prohibited by US federal law.
Visitors who are of age can use pot while in Canada, but they can’t take it with them when they go.
