I really can't comment on how bad heroine is; only known occasional users in person, but I'll admit, all of them seemed fine to me. I haven't kept up with any of them though, so for all I know they died the day after I last spoke to them or something.I realize meth is supposed to be basically the worst most destructive drug on the planet, but... well, even if it is, and for argument's sake lets assume so: should it be judged by the damage the actual chemical itself causes, or judged by the damage the chemical causes you to cause yourself? As in frequent/constant exhaustion, starvation, malnutrition, and dehydration. On the one hand, any tweaker that's lost their grip is going to be doing these awful things to their bodies; but on the other hand, that's damage that could be virtually eliminated by more careful usage. So really you can go either way.Who knows, maybe they choose to evaluate heroine in an overall lifestyle fashion instead of what the drug itself does. shrug. Just a thought.
