a-pvp suggested above, is an incredibly powerful stimulant that is smoked and its stimulation is far more than crack or meth. You can see videos of what it does to people,it's insanely strong. 4-mmc which I;m very familiar with , is identical to mdma in my experiences far LESS stimulating than cocaine and with a psychedelic euphoria. there are many routes to synthesisize cocaine and as far as I know they all involve 2-cmt being made and that being further reacted into cocaine. A dozen reasctions at least. If there are any that don.t I hven't seen it, and I might be skeptical,
