There's still real heroin in the US, but from what I understand from my northern point of view, chances that people west of the rockies do not get fent contaminated tar. It's still the same ol' tar. Although me who was such a freak about cleanliness when shooting up brand name Dillies 4mg and 8mg....I'd have a hard time slamming tar...ugh, no wonder its the only thing you really gotta heat up before shooting up. As for snorting tar...I only heard it in a book about Nirvana I have, Kurt actually was rarely slamming heroin, he smoked tar, and he did what he called "wet snorts", I don't know how one does that, snorting tar, but I guess you add a little water to it?
I'm on Suboxone and never had heroin, I've seen the kind of heroin we got down in Montreal, which is #3, brown stuff that looks like very good hash that can't be slammed unless you add citric acid? Anyway, the party I was at, the people partaking all used foil and a cut in half small bottle of soda, its similar to smoking hot knives of oil with aluminum...those who do that sicken me but what are you gonna do....when I smoked hash oil, which back in 2004-2005 I had access to a hell lot for very cheap, i would put some on one knife and only heat another one with the blowtorch worked perfectly, I don't know why some insist on putting oil inside a little square of tinfoil and smoke that....i'm sure aluminum particles get inside their brains doing that. Off-topic tangent but related, I'm not sure foil is the best way to smoke heroin, I hear just adding powder caffeine to that #3, one can smoke it in a weed pipe easily. But I never dared, because, the only time I saw it, I already was slamming HydromorphContins 9mg and Talwins every couple hours at that party, had already spent my "party" money big time and the stuff was EXPENSIVE, but at least its pure. That was just 4 years ago, don't live in Montreal anymore, but I'm sure its what they still get, we don't have people falling down from fent cut "ECP" here, it manages to get inside southern ontario, which is part of the US if you ask me, imagine all the shit that goes from Detroit into Windsor, or from whatever town the other side of Sarnia,ON.
