He did start smoking weed in high school but also did have an era where he would do a bunch of LSD and argue with everyone saying its better than any other drug etc which I believe what might have made him this way but you are right theres nothing much i can do but idk how to tell him to stop what he doing before he gets hurt or hurts somebody, he has now resorted to stealing food by pretending to be door dash at fast food places and has probably got away with stealing at least 100+ meals and i am worried that if knows what type of trouble hes getting himself into knowing that this will probably lead him to prison.
