Answers (2) The half life of Adderall is about 10 hours. This means that every 10 hours, half of the previous amount of Adderall in the body disappears. For example, if you took 10mg of Adderall at 12AM (midnight), at 10AM 5mg of Adderall will be left in your body. At 8PM, 2.5mg will be left, and so forth until there is 0mg left in your body. As a rough guide it takes about 5.5 half lives for a drug to be out of your system.
