Methylphenidate is a psychostimulant drug approved for treatment of attention-deficit hyperactivity disorder, Postural Orthostatic Tachycardia Syndrome, and narcolepsy. Ritalin is it's brand name. Methylphenidate and amphetamine have been investigated as a chemical replacement for the treatment of cocaine dependence. If you were treated with Ritalin for cocaine consuption, a drug test will no show it a a false positive for cocaine.
It is hard to find a drug test that doesn't test for opiates. however my friend is joining the NAVY and he tells me that during his DET meetings they only test for amphetamines cocaine and marijuana. so to answer your question it is most likely probable that a drug test will test for opiates, marijuana cocaine and amphetamines
