Hi I am a recovering crack addict as well and I know many other crack users. Some recovering, some not. Some saying they want to quit and some are committed to being crackheads for the rest of their lives.
The ONLY way to help a crack addict is to get out of the way and let them hit bottom. Don't enable. Don't support their addiction. Don't give them money. Don't try to regulate their drug useage. Don't protect them when they make mistakes. Don't listen and accept their lies. Protect yourself. Protect your things. Don't be a doormat. Just get out of the way and let them fall as far and as hard as they need to.
It's so hard. But a crack addict has to do the work for recovery on their own. If they don't accept responsibility, well then they never will. Nothing we do or say can help them.
Actions speak louder than words when it comes to addiction. You don't just "WANT" to get better. You have to take steps. You have to work at it for the rest of your life.
Anyway, that's the scoop on crack addiction.
Keep posting, reading and working on yourself. Don't let his addiction become your addiction...
