Every country I've traveled too since age 17, I've boughten local product and loved to smoking in whatever country I was in. Small amounts of marijuana are usually administrative fines, if anything, in most of western Europe, Australia, Mexico & Canada. You can bribe most officials in central and southern America as well as Africa, and the majority of the south Pacific.

You only have to worry when you get into Asian or Middle-Eastern countries. Small amounts of anything in those countries will get you FUCKED for years if you're not careful.
