Adderall is a form of speed and is addictive. Adderall revs you up; pot calms you down.
Adderall side effects: For some people it will make them a zombie, and some people will want to clean a house or build an entire structure while on adderall. Sleepless nights and lack of appetite are sure to come with adderall when starting out, after a while he will adjust to it and lessen side effects. Adderall likes to leave a bad taste in the mouth and some people's sexual drive increases because it is amphetamine. I was on Ritalin as a child, and put on Adderall when I was around 15. It gave me the zombie effect, but people say that means the drug was meant for people like me. (ADD)
Smoking pot may in fact increase the feeling the Adderall gives him, but it will also help him eat and sleep if he's having trouble with either. The biggest problem with these 2 together are the long term effects. Taking the biggest upper a Dr can prescribe and then adding a downer with that isn't the best idea, but I did it. (I don't have the best ideas)
