Adderall contains a mixture of amphetamine salts used most often for the treatment of ADD/ADHD and narcolepsy, but is used for other conditions too.
Amphetamines (commonly called uppers) are synthetic drugs that make the user feel more alert and energetic while suppressing appetite and fatigue.
First of all, the right spelling of the medication is Adderall (Aderoll is a common misspelling). 120 pounds is a weight of a slim adult person. Adults may start with 10 or even 20 mg of Adderall, gradually increasing the dose week by week if necessary up to 120 or even 160 mg per day in total. A daily dose of Adderall has to be divided into equal parts and taken every several hours to maintain the attention at a higher level, or taken once a day if it does not exceed 60 mg. It has been shown that the higher tolerated dose, the better the response. However, you should never exceed the dose recommended to you by your doctor.
I do not condone using any kind of pills to get high as it is highly addictive and can cause major withdrawals that are terrible. I used to take pills such as lortab, vicodin, and xanax to get high and ended up becoming dependent on them. I had the worst withdrawals ever that made me never want to take a pill again. Cold sweats, diarrhea, vomiting, my whole body was in awful pain. I suggest if you would like the high feeling, just don't do it every day so you don't become addicted to it. Also, the more you take the more tolerance you build and you wont feel high anymore from it. For recreational use, do it minimally if you must. Best of luck to you!
