It is very unlikely for a child to grow out of their ADHD symptoms, but this does not mean your son is doomed to the life he is currently choosing to lead. Judging by his school work he has the ability to do more with his life than smoke weed. From your post it seems as though he is no longer on Ritalin. I wonder why this is? Were his symptoms more controlled on Ritalin? A known side effect of Ritalin is a decreased appetite and therefore weight loss; he can take a supplement such as Ensure to keep his nutrition up. I would strongly suggest he see a psychologist to find a coping strategy other than grass. Most people with ADHD fear the thought of having to study after school as it is such a difficult task for them; however, they do very well at Technikons where the study is more practically focused. The short term goal is to get to the bottom of his grass smoking and replacing it with a healthier coping strategy.
