3 to 4 days: The half life of elimination for Adderall (dextroamphetamine and racemic amphetamine) is about 14 hours. This means that it takes 14 hours for the body to eliminate half of whatever is present. Let's say you start at a level of "100" in 14 hours, the level will be "50". In *another* 14 hours, the level will be "25. And in another *14* hours, it will be "12.5" and so on. Levels will be negligible in 3 to 4 days.
