if its hotrailed i beleive it would be , Its a gas/vapour going into your lungs.
however many ppl here are hooked to regular amp. WAY TOO MANY! it's shitty drug and destroys many people and their families. However I would love to try meth.
okay, since this is so terribly important, let me clarify. I meant to say MUCUS MEMBRANES, but if you sniff it hard enough to get into your lungs, yes it would be absorbed there. I don't understand why people have to get up in arms about trivial shit, when that has nothing to do with the point. The point was, it gets in faster, whether it be in your lungs, or your throat or your nose.
