What is the half life of Adderall?

The half life of Adderall is about 10 hours.
This means that every 10 hours, half of the amount of Adderall in the body is removed, then in the next 10 hours half of the remaining Adderall is removed and that continues until it is all cleared.
It takes 5.5 elimination half lives for a medicine to be cleared from your system, therefore Adderall will be in your system at least 55 hours (5.5 x 10hrs).
Elimination of drugs can also be affected by other factors, so elimination may vary according to individual circumstances.
