Yeah I'm not sure where they got their facts on heroin from...
If Heroin now is indeed 90% pure, that's a GOOD thing! It means there's less rat poison and shit in there.
However, I truley doubt that, because a black market is still a market - and people can't make a profit selling heroin that's 90% pure for $5...
perhaps its considerably cheaper in the US? I can't imagine so tho...
