There's nothing whatsoever wrong with abstaining from drugs, or hard drugs. In fact, I'm sure just about everyone here would agree that it's commendable, and will only make your life easier in the long run, if not "better," "more fulfilled," or "more successful."
That being said, I think that you may have misunderstood the purpose of this thread a little bit. It isn't the fact that his friend doesn't want to try these drugs that he's complaining about, but the fact that his friend feels the need to express it to him, probably frequently, when it's not an issue that's even relevant to said friend.
No offense, though, I respect the hell out of you both for your posts at the end of Jimbo's crack thread, and for your avatar.
