don't. I tried it a few times in my younger years(16-20). The first time, I thought it sucked. I tried it a few more times just to make sure I didn't just get a bad batch the first time or two. Sure enough.... no big thrill. It just made me unable to make sense of the thoughts in my head. No euphoria. I didn't dig it.
I had it once when i was drunk (the only state when i would have considered doing it, lol) and I decided its WAAAYY too overated. Yeah it made me feel a little light headed but it definately wasnt anything i'd consider special.
Seriously, there are MUCH BETTER drugs out there. If I didn't get random drug screnes ALL the FUGGin' time since I carry narcotics at work........ I would probably still be doing some really bad .... but REALLY good sh*t.
