Thanks for the reponses. I plan to bring both bottles and a copy of each prescription to the test. However, that is not my question.
FYI, ritalin is not an amphetamine.
I have a prescriptions to take Clonazepam and Ritalin and a drug screen coming up before clinicals rotations. Two questions: First, are either of these drugs that they will be screening for? Second, could either one give me a false positive for something else, especially the Ritalin?
