My 18 year old son smokes weed and openly discusses it. While I hate that he does this I’ve always been grateful to at least know what’s going on. There has been some recent changes in his behavior that have me very concerned he is doing more than just marijuana. Symptoms include: Not changing his clothes for 2 week straight Tiny red bumps all over both of his legs that are scabbed over (30 on each leg) Decrease in appetite Extreme lazyness and lack of social interaction Sudden Aggressive behavior He spent about an hour in the shower the other day and when he got out the picture attached was in my toilet. It was very tar like and hard to clean. I had to scrub the toilet for about 10 minutes before I got it out. He doesn’t have injection marks anywhere that I can see and has never been able to swallow pills. Help me! Does this sound like he might be doing something other than weed? If so what could it be?
