Hi Molly,
I dont have experience in crack addiction, but I presume its quite similar to cocaine. I dont want to teach you to suck eggs, but can you get him to visit a dr?
Crack is going to kill his pleasure receptors, so that he wont easily find pleasure with anything else. Also the more they do, the more it just becomes that you have to use it to feel normal, not good, just normal. Thats because he’s addicted right. Thats why coke and crack are sly drugs, they reel you in with a ‘good feeling’ then it takes more to achieve that feeling, then you get to the point where your son is now, which is using to feel normal, not even to feel good.
I don’t know what to say to help you, can you get him into rehab? Or isnt he interested? If he’s not then maybe tough love, he is 30, he has to move out.
