Speaking from Nimbliez better half..., after spending years trying to finding something for A.D.D. I have come to the conclusion that there is absolutely NO hope for someone with ADD, Do not ask your doctor these questions. Do not grow herb at your parent's house. Wait till your at least 25 when your brain has reached full development and smoke for enjoyment. It doesn't help anything to aleviate the symptoms of ADD. You'll have it for the rest of your life, so enjoy it to the best of your abilities.
PS Einstine was ADHD (attention deficit hyperactive disorder), we're smart, we're creative, just go for it.
