I was curious as to how much heroin would put me into an overdose and kill me. Not that I'm going to do such a thing, but I'd like to know. Ive never done H before but I've done enough prescription opiates to know a little about it. What delivery system would be most effective? I understand that this is harm reduction, but I'd like to know at what level would I be playing with fire and get scorched. All responses are appreciated
