is usually, if not always heroin 3 as in number 3. This is in contrast to heroin 4 which goes through an extra step to make it into the salt heroin hydrochloride, similar to cocaine
. Basically heroin 3 is like crack as in it's in base form and heroin 4 is like cocaine because it's in a salt form and soluble in water. As far as i know you can still smoke heroin 4, but i don't think it 'runs' on tin foil the way brown heroin 3 base does, but i can't speak from experience.
The purity of brown heroin can vary widely from place to place and from dealer to dealer. If it's in a rock it doesn't necessarily mean it's more pure, it just means someone has pressed it in to rocks. Never the less, getting rocks is probably a better indication that it hasn't been cut to same degree that powder may
have been cut too. Purity can range so much, from 10% (or less) to 60% maybe more, there really isn't a way to tell from looking at the heroin itself, and even after consumption, it is still anyone's guess.
Brown smack shouldn't bubble at all while running it on the foil, the only way it would bubble is if you don't run it and heat it in the one place, you shouldn't do this, it should be ran in lines. Most brown smack will leave a residue from these lines, generally the less the better but not always, when it fries or 'pops' at the end it should only be a small amount, but it will bubble and leave a small amount of charred 'beetle' on the foil but this should be no more ash than say a flick of a cigarette. If it pops after only a few lines then it's probably being cut to hell, and if this keeps happening from the same source then one should change sources and try to get better gear.
Brown heroin is injected all the time, but as with anything it does have risks, probably more than heroin 4 which would be soluble in water with the adulterants hopefully not dissolving. That said, i wouldn't say it's much more dangerous to inject brown heroin, at least beyond the obvious. But it will require an acid, usually citric acid to turn the base in to a salt (heroin citrate). Generally 100mg of citric acid should be able to dissolve 1 gram of relatively high purity brown heroin, the less pure the less acid required.
This placing heroin under a cut in the skin, i think that is crazy, ridiculous even, where did you hear this? Maybe you mean a subcutaneous injection
(skin popping)? I would advise against this unless it is necessary, ie. you don't have any veins. Skin popping and muscle popping (subcutaneous and intra muscular injection) is against the advice the UK drug
services are giving, it allows the solution to remain in one site possibly allowing infection to start. There have been a few cases of the flesh eating bacteria killing people in the UK because they used these methods of injecting, either that or they 'missed' the vein and the infection was allowed to take hold.
My advice would be to continue smoking it, or if one thinks they get good or better effects from snorting
it, then i see no reason not to continue doing that, apart from the whole addiction
thing of course. Speaking of addiction, first and foremost i would say stay away from heroin, no one can control their habit and in the end it always controls them, take it from some one that knows first hand and seeing it happening to many friends and people i know.
