if he was using needles, i really don't think he would go out of the way to bring q-tips. if a needle user doesn't have cotton near by they tend to use a cigarette filter... my thought is that when one does coke, it tends to dry up the nose, maybe its for that? I know it sounds so gross, but a tissue will not cut it, he might want to ug I can't believe I saying it, "get up there" to clean out his nose. I know if you keep your nose clean, it helps from getting clogged later.... this is just a far out thought.
