I commend you on steering clear of that shit (referring to the drug scene).
I agree with HOSTILE when it comes to "fuck people". You should always have sex with human beings; not animals, objects, etc.
I don't, however, agree with "who needs friends?"
There comes a time in everyone's life when their left/right hand stops being so amusing. Shoot, dude, you mentioned you're a part of a local club.
If most of the people around your age are doing that junk, avoid those, and try to get in with the few that don't. That already gives you a topic of conversation, since you've already made a point of connection between you and whoever it is you speak with. Both of you dislike using drugs.
If they're in the club, shit, they must like music. They must also like meeting other people. Isn't that kinda what you want to do? Meet people?
I guess I'm making it sound more simple than it really is; but in essence it's just about seeing where you can strike up a conversation. Once you've done that, you can end it with a "let's hang out again sometime".
