How long will adderall (dextroamphetamine and racemic amphetamine) make you test possitive for amphetime?

Depends: Depends on your body, the preparation u r using (e.g., xr), the amounts u use daily and possibly your liver and kidney function, and the type of drug test (whether urine, blood, sweat, saliva or hair). If you have an addiction problem, please seek help for same asap rather than worrying about how to get a clean drug test. Life is too short to live it in the haze of addiction.
