I've been drinking with friends since I was 13 (not saying it's a good idea) and I had no problem with it. Hell, I did all sorts of crazy stuff when I was a kid. However, when a few of my friends started taking drugs (pills/shrooms) I left them to it and found others to hang out with. They soon learnt from their mistakes (although unfortunately for some, too late).
Basically, if it makes you uncomfortable, don't hang out with them and find mates that are into what you're into. Don't give into peer pressure or do it cause they are. Serious.
