My husband smokes Fake Weed

I just need to rant for a minute. So my SO just got home from prison end of October. Well before he got home I was addicted to fake weed. But stopped when he got out. But come to find out he was smoking it while locked up. He is still smoking it now even tho he is on parole. All he does is smoke sleep eat. Smoke sleep eat. I'm 15w2 now and all I wanna do is scream and beat the hell out of him. I've made it clear that I don't like him smoking. I don't smoke anymore but he is addicted to it. Idk what to do anymore. This is my US at 12w
