Me neither for the most part. My old flatmate can get shrooms fairly easily but he only uses them at festivals and such. He's never offered one although we've talked about going to festivals together recently, and talked about all kinds of drug experiences many times. I've tried to make it a policy not to push other people for their drugs, but they are a curiosity.
I did take Salvia once or twice, purely because it was supposedly a super short trip. It is a short trip, but it was very strange. Just thought the walls were turning into charmin ultra. A couple of my mates used to play pranks on people by putting some salvia on the top of the bong, that kind of behaviour is completely twattish.
My old flatmate (as well incidentally) tried to sell shrooms to me, I got put off by the fact that he said "and the first thing that happens is, you vomit loads".......My reaction was simply "ok, think I'll give it a miss then." I guess, I also don't like the idea of having a bad trip.
Obviously, if they are a curiousity, go for it at some point. The main thing I did when trying anything new, would be to find out about it first, and take it with someone who had tried it before and knew what to expect.
Depends on the venue for me overall, and I'd certainly be too lazy to dance with heavy use (although music gigs and stuff I'm fine with), but I might smoke a J an hour or so before going out to the pub or something. Marijuana is now rightly considered an anti-nausea medication in some parts of the world, so I've found that measured use planned around isolated instances of alcohol intake is quite a good balance as long as it's accompanied by some mental discipline.
I get where you are coming from on that one. I can cope with a pub after a joint or two, but it's just I often don't like to drink booze much when high. I just nurse a beer per hour or hour and a half. If I drink first, then have a joint. I used to whitey back in the day, now I just end up falling asleep instantly. Maybe it would be different if you were certain to have a sativa strain, those are better for going out on.
