Will mdma or mda test positive as opiates?

No, MDMA and MDA are not similar to opiates at all and will not break down in the human body to anything resembling an opiate, thus they will not test positive for opiates. However, they can test positive for amphetamines. MDMA stands for methylenedioxymethamphetamine and MDA stands for Methylenedioxyamphetamine...Go figure... And further complicating the matter, Extacy pills are nortoriously impure, so it is possible that what you thought contained MDMA or MDA had other stuff in it, possible an opiate or another testable drug.
