Will adderall xr show up as crystal meth in urinalysis?

On a drug test they test for Amphetamine, both Adderall and Methamphetamine are under this category. Unfortunately, they can't distinguish what type of amphetamine and normally assume the worst; just remember if you fail for amphetamine that means you fail for all drugs classified as amphetamines. Also amphetamines will only show up in urine for 2-4 days! Large quantities of Vitamin C and other acidic nutrients will help cut down this time.
