if you're going to try it, i suggest smoking it. the technique of smoking isn't all that hard, you just heat the glass where you want the ice to hit because you're rolling the pipe back and forth with you finger. you always keep the flame ahead of the molten ice, and not directly underneath. you can burn it and burnt meth tastes...bad.
there's a myth about getting soot from a cigarette lighter on the glass. total bullshit.
smoking ice will get you the effect faster, its WAY more fun, doesn't hurt at all, and is easier to regulate you usage.
i gotta say though, that for me, all it took was one hit. some random at a party handed me a pipe and said try this... so i did. and went on a continuous 3yr binge after that.
maybe some people can try it just once, but there's a whole bunch of people that can't.
