Depends: A single standard dose of Adderall (dextroamphetamine and racemic amphetamine) is usually completely eliminated after 1 day; the half life is 10 hours approx so half of the dose gets removed in every 10 hours.

About one week: Adderall (dextroamphetamine and racemic amphetamine) can be detected on a urine drug test up to one week since the last dose. Usually, it's more like three to five days, depending on the dose. A higher dose takes longer to clear. One week is about the longest.
