He started smoking marijuana when he was 12. But now all he do is sleep & he is getting a lot darker! He sleeps from 10 in the morning until like 9 at night! He always look drowsy & out of it.. I told my mom that I think he is doing a lot more than smoking weed. It’s even getting to the point of him stealing money from my mother & my sisters. He stays out all night & when he comes in the house he looks very drowsy & zoned out and goes straight to sleep & he sleeps all day & then he will leave out at like 9 at night! I wanted to know what drug are these symptoms affiliated with & how can I help him?
