I find it unrealistic for people to say they're never going to drink. You may not enjoy it, but I think that it's inevitable. xD;
I've only gotten buzzed once, and by accident. My friend's brother spiked the punch we were drinking and it was too hot for us to notice or care. As for smoking and drugs, both of those are a no-no. I still think people should be allowed to smoke on balconies and on the street though, it's a choice and taking that choice away seems very...hitler-ish?(Yes, that's a word. I invented it.)
