Regular release Adderall is usually gone from a person's system in  24 to 36 hours. The extended release Adderall is usually out of a  person's system in 60 to 78 hours. Thiâ¦s can vary from person to  person depending on how quickly their body metabolizes the  medication.
Dextroamphetamine, the main component of Adderall, has a half-life of 10-12 hours according to the FDA [1]. For the drug to drop to negligible levels in your body, it takes over 2 days. The livers of different people break down the drug at different speeds, so Adderall exits some bodies more quickly. Hence, for some people the drug might be detected in a urine test even on day 3.
