I live in Quebec and weed is still "illegal" (no real laws for it since 2001, but cops keep arresting people). If you smoke at night or in a concealed place where not too much people see you there's no problem. I smoke at parties and around midnight around schools, libraries and forest and I've never saw any cops coming for me or somone else. They do arrest dealers tho. I guess it's more relaxed in BC.

Good Luck, and Good smoking,
Dewave.
