Nothing you can do at this point really. Good that you did not let him come home.
I agree, he should be in rehab. My son almost died from an opiate overdose on Father's Day. He had been clean for four months and was in sober living. He did not seek it out but his girlfriends mother had them and he took some of hers. He had a fit about going back into rehab but it was that or the street - that is what we told him and I will continue to tell him. I am terrified of opiates. I think they think they can control it.
It's hard. I can't force him to want to be sober or be in rehab but I can keep myself from enabling him.
This is such hard work. Hugs to you.
