he was a bad drug addict,who knows the story
He's walking around and functioning somewhat normally...I think you can drop the "bad" term. He probably liked to eat a few norcos above his prescribed amount. A "bad" drug addict is the guy underneath an abandoned bridge slamming his morning horse into the necrotic stump that used to be his left arm.
drugs are great but only a few can deal with it.
reality is for those who can't handle drugs.
