SO I've got a recently turned 17 year old that I've just found out is sneaking around and smoking the devils lettuce he's getting from a friend ( the friend may be getting it from his parents, unconfirmed). He has a problem with alcohol we found out about last year, as far as I know he hasnt had any since( he almost killed himself with it) . How do I go after this? Confronting him about things in a harsh way makes him just retract and lean into it harder, having discussions with him he just ignores. I'm his step dad, been in the picture since he was 1, but his dad, sister and now him seems to be highly susceptible to addiction. as soon as she moved out, she got into weed and within a year we were putting her into rehab for meth. Her dad did the things when he was young. just worried about pushing him into this stuff...Thanks in advance!
