Whoever wrote this article seems to have little knowledge of the drug and just google searched and posted the first things they found. Also the word “psychogenic” is an incorrect use of that word. The word you were looking for was “psychotropic” or “psychoactive”. Also MDMA=XTC Molly=MDMA (most of the time) XTC=pressed pill containing MDMA, but can contain other substances. When first introduced people refereed to any form of MDMA as XTC. The term molly is relatively new and has caused quite a lot of confusion. In short MDMA is XTC and Molly, but Molly and XTC tablets might not be MDMA.
