These hair tests are very accurate, usually. I have never seen Adderall (dextroamphetamine and racemic amphetamine) do this. But, perhaps you could google that. It definitely is not the marijuana. The most common HIV meds also would not do this. I googled this and there is some discussion about dental anesthesia, the common antibiotic amoxicillin. Request a urine test which will be negative and then ask for explanation.
