You have never used speed? When i was younger there was no crystal meth, it was all powder meth (or glug) and people didn't smoke it hardly ever except on 'snowcones'.. I didnt form an addiction then just once a month or more at raves or whatever, then crystal meth came here about yr 2000 or so and alot of my friends started smoking it like some people do bongs or ciggies and I thought no way do I wanna do that and stopped. Now most my friends never see powder or glug, they only see crystals/shards/glass.
It's all meth tho apparently, powder, glug, crystal. I just find the crystals are more expensive and more addictive and more powerful, not sure if all that is true, but yeh i dont use it anymore havent for along time.
And if you use mdma a bit as your name suggests, I guess you have had a fair few pills over your time? I hope you test them all, as I know around the place I live in heaps have had meth/speed in them, some times speed bombs do the rounds as E's alot over here. I've tested loads of pills and quite a few have come up with a positive reaction to meth/speed.
