I'd just like to say that I'm not bitching about speed being cut with *something*. That's fine -- I mean I don't give a fuck if you want to sell me 10% amp and 90% lactose or something, if you tell me it's 10% amphetamine and cut the price proportionately I'll buy a goddamn kilo of it.Also, caffeine and amphetamine are generally soluble in the same things, so it's very difficult to separate the two molecules. It's not like you can just do a dry acetone wash and have clean speed again. I know of no way, but I'm not a chemist, so I don't doubt there is one.
