You don't say how old your son is, but you guys really aren't doing him any favors by keeping him from experiencing the consequences of his bad decisions. Maybe if you present it to your husband that way, he'll be willing to step out of the way of your son and his bottom. Addicts don't desire recovery until they are so miserable that they are willing to do whatever is necessary to better themselves. If your son has a nice home to live in, a soft bed to sleep in, plenty of food to eat and access to valuables to pawn or sell to feed his habit, why would he want to change? He has it made.
