Easy for you to stand in judgment. I have an old friend, talented musician, brilliant guy really. Heroin tends to run in musical circles. He got addicted, and has gotten himself off it many times over the years but it always pulls him back in. He'll never be free of it, and it's not due to lack of will or character weakness. It's just that strong of an addiction. I have no doubt it'll eventually be what kills him and for that I mourn.
He just needs to stop. It remind me of the guy that goes to the Doctor and tells HIM that “my arm hurts when I go like this.” The Doctor says “ Don’t go like that “ and bills him $100.
