My friends don't seem to respect the fact that I'm straight edge (no drink, no drugs, no smoking). They drink very rarely, don't get drunk and don't smoke, so they're really not much different. We are all 16/17. How can I get them to stop making fun of me for my choice?

Friends tease each other ... But they also stop, when asked.

So if you've asked them to stop, and they don't ... They aren't really friends.  Go find some new friends.
