I know a guy who deals in weed, but every now if the right deal comes around he'll deal in coke. He's one of those niche dealers, who refuses to sell shit. So he has relatively few customers who buy higher end bud. Anyhow, the problem with coke is, even when the price is good, the coke is usually shit. He says it's to the point where it's getting so cut that half the time it's hardly white anymore. Says he doesn't know why people even bother with it, it's gone so far to hell.
Anyhow, point being, 20 a gram? For 5 bucks you can sniff the dust from behind my TV. 15 bucks cheaper and just as effective, I'd bet. Probably safer for you too.
