Kklost,
I did know my husband did it socially in his 30’s. I got him help 8 years ago and he stopped for 2 years, in that 2 years we had a child. Things were good, he was and still is on medication for depression, i’m not sure which came first, the drug abuse or the depression…. Then for the last 6 years he’s yoyo’d on an off it. He made the mistake of believing he could do it every now and then and not spiral back to daily. He cant. Its like telling a alcoholic to have a glass of wine every now and then.
You are doing everything right, and you sound methodical in your approach. Just remember to take time for you, you’ll need it.
Take care of him and you, its not easy stopping the evil drug. He’ll probably need to distance certain people (you’ll probably know who they are) and really wont be able to drink alcohol, as thats a trigger which lets your guard down so he’ll be more likely to relapse if he drinks. I was never a big drinker, but I don’t drink now either. I don’t want to give him temptation.
Theres a timeline of recovery here https://addictionblog.org/infographics/cocaine-withdrawal-timeline/ and beware re the urine tests, my husband had been using daily for months, and the tests were still positive for about 10-14 days after he stopped.
Take care x
