I took an "ecstasy" tablet once (2 actually) that I believe was PMA, not MDMA. Para-Methoxyamphetamine. I had such bad anxiety and tightness throughout my body along with severe anxiety. I felt at times that I was likely going to die, which of course was pretty much nonsense. However, there are dangerous cuts/imposters out there that can indeed be quite harmful.
