Just fyi, that buddy of mine started rehab yesterday for the first time. I'm not that cloise to him so I don't know if he was only doing mephedrone or if he had been doing mephedrone and crystal meth. But from what I heard he hadn't been doing meth for awhile. Just thought I'd mention it though just incase.A buddy of mine is a ex meth head and he will smoke a gram of Mephedrone in less than 12 hours. He loves it. Says it gives him somewhat the same feeling as crystal meth used to. I tried it once and it burnt too easy, but I'm not the best at heating such a thing. Would think it would be a waste.
