It's the only hallucinogen I've ever done (easy to get, convenient if you only have like twenty minutes to spare), so with nothing to compare it to, I just kind of take it as the baseline experience. Did it with my druggie friend one time, though, and he seemed to hold your position. Said it was too intense, swore never to do it again. Funny, because I find it really relaxing. Each their own. Your response makes me wish I'd had the opportunity to try other ones, though. Ayuhuasca is sounding pretty great from this thread...
I pretty much observed 3 general reactions to salvia: 1) nothing. 2) laughing non-stop about nothing for 10 minutes straight 3) actually affecting you in a typical hallucinogen (albeit more harshly than other), ranging from freaking the hell out to calm euphoria If you're still on this earth, you've still got time, just try to aim for reputable sources, though that's easier said than done. However, if you're straight-edge or sober, don't let all this talk lead you astray!
Hah, not straight edge or sober- do have a family, though, which kind of disqualifies me from day-long vision quests. Maybe if at any time I get a weekend with friends or something.
