My son is 26-year-old and I recently found out that he did Coke at my younger daughter‘s wedding and then did Coke on Christmas Eve and found out from his father that he did Coke with his father his father‘s girlfriend on New Year’s Eve. My son is in the process of breaking up with his girlfriend who is a very good influence on him and hanging out with one of his old classmates who I just found out sellls to him. I am in and out of town but I have been a constant in his life. He’s coming over for a visit in the next day or so but he doesn’t know that I’m going to address him about his cook use. I have talked to his father which I reamed out and his father admits he was wrong for doing Coke with his son but his father has had problems with drugs all his adult life . I am thinking about contacting the person I know who sold it to my son and threatening him as well my son and my ex-husband that if they ever give him Coke again I will turn the in, just not sure for safety reasons if that’s a good idea. Unfortunately my son has always idolized father and has evened pop pills as well as snorted pills with his father in the past. I have had my son arrested once because he use my car to go pick up some pills and we got into an argument about it and he punched my window and broke it so I had him arrested He did have to complete a rehab program but it doesn’t sound like it’s stuck He has a job goes to work but from what I understand his Coke habit is increasing. Not sure what to do about his idiotic father and my son any advice would be great.
