I am currently on probation and give urine samples once a week. I also am taking Adderall.  The drug screen that is used on the samples I submit test for: 1) THC 2) Cocaine 3) Benzodiazapine 4) Opiates 5) OxyContin 6) Amphetamine 7) Meth   The Adderall flags both the Amphetamine and Meth test strips.  They had to send my test to a lab for further analysis due to my addamance that I had not consumed any illegal drugs.  My doctor told me that when a person consumes Amphetamines, that the body metabolizes them into Meth Amphetamines.  Being a recovering addict and doctor who treats addicts, I have full confidence in his knowledge on the subject.
