Adderall is a methamphetamine. Yes, adderall can show up on a urine analysis for almost a week after taking it. But that depends on the detection level of the test. I've been prescribed adderall for almost 13 years now and I've had UA's done before for health reasons. If UA they ordered is a high detection one, it will definitely show up. If the test is a cheaper low detection one, it may not show up at all. Your weight, the amount you took, when you took it, etc is also a factor in detection. A lot of employers don't want to shell out the money for a higher detection test, but law enforcement, doctors, and courts will.
Adderall shows positive for "amphetamine" not methamphetamine" ... Two separate metabolytes are tested for
