Hubs relapsed

I’m not sure how to help him get sober at this point. We’ve talked and talked and talked about it he knows it’s a problem but then tonight I come home and he’s high as a kite and I blame the neighbor. The neighbor grew up with his family and he sweared he had gotten sober. Since a couple weeks that he moved by us I noticed my hubs being away from home more and more and he says they’re just fishing or theyre just hanging out whatever. I’ve started finding pills hidden and i throw them out. I don’t think he wants help and Is just saying what I want to hear I don’t know what to do.
