So, Medical professionals feel free to chime in... I have seen yes, and seen no as an answer to this question. While taking Concerta XL, can you test a positive for amphetamines on a 5 panel drug screen? I was told to tell them I was on the med, in case I tested positive. I didnt get that job, which was just waiting on the drug screen. I dont know what the results of the test were, except I never heard back from the employer. Leads me to think I was positive. Any thoughts?
