Not once on here have I actually seen someone get coke that is even close to pure, it always has levamisole or some amphetamines/ephedrine in it. Is coke really that worth it to try to hunt down pure shit because not only does it actually not seem possible, the drug itself (to me and others I've talked to) isn't really that worth the trouble to try to get good stuff by the time you do have it anyway when you could've saved yourself the trouble and gotten some kind of other stimulant like meth or amphetamine. Or maybe the drug is worth it to some even if they have to snort levamisole and shit up their nose every time just to get some basic stimulant high, who knows
It's absolutely worth it. I'd rather spend $200 a gram on great coke than $100 on some ok coke.
As far as being worth it or not: coke is like cigarettes. You either love it or you don't.
