My son failed a drug test for MDMA which he was told is ectasy, but he is adamant he did not take it. He is being pressurised into a 14 day answer and we need medical professional advice as to what else could have caused it, do you have anyone we can consult?
Keith Borers in the UK can run those tests for you

However this will be expensive and from my knowledge of MDMA. It is the active ingredient in ecstacy and is often taken as a stand alone substance. There isn't really any other cause for it
