Right, that may be true, heroin is a waste for those individuals already addicted.
But for those of us not yet addicted and not looking to become physically dependent anytime soon, we believe that shooting heroin for the first time is called "the one hit wonder" for a reason.
So you may think snorting is a waste, but not once have I experienced withdrawals, and that's worth "wasting" some of the substance if you ask me.
EDIT: That isn't to say a person
can't become addicted / physically dependent by snorting heroin, but from what I have been told by those far more experienced, it's shooting heroin that really did them in... I'm not sure how true it is, but I haven't experienced any negative consequences so far by snorting heroin, so I'll just keep doing what I'm doing...
