I have inattentive ADD. To be honest, smoking pot makes me feel even more ADDish than I usually do. Actually, 'attention deficit disorder' is kind of a misnomer, since most people with ADD can focus extremely well, just on all the wrong things. When I'm stoned, that's compounded. I'm easily distracted by shiny objects, and if I go into work even a day after being stoned, I'm constantly forgetting things and losing track of what I'm supposed to be doing.

I know there are people who will read this thread and think that they'd like to use pot to treat their ADD, but at least for me, adderall helps me keep my focus whereas weed would make me lose it. I'll admit it might be helpful for people with the hyperactive variety, but be aware that it can definitely make things worse.
