Yeah, i'm inclined to agree with this.
"Asia" is a pretty broad geographical region - with some drug-producing, drug-smuggling and drug-filled countries within it...but as Trozzle points out, the penalties for getting caught in some Asian countries are among the harshest in the world.
Judicious use of the bluelight search engine would probably provide you with all of the information you are looking for, but as "drug tourism" is a fairly frowned-upon (and illegal) practice, i don't think i can allow this thread to stay open.
Sorry mate.
