Okay, you can be personally excited about therapeutic MDMA possibilities without making up a "gold standard’.
The study I’ve linked to above is specifically for psilocybin treating PTSD with an 80% efficacy rate after one entirely safe dose for 6 to 12 months.
The link you’ve supplied, as far as I can tell, does not report conclusive results for MDMA treating PTSD.
MDMA is not a gold standard, it’s one non-standardized psychedelic therapeutic possibility that is physiologically more dangerous with fewer studies, more risks and more time commitment, therapeutic prerequisites and necessary conditions than psilocybin, without the resulting necessary controlled and conclusive clinical trials providing evidence of effective treatment.
I stand by my original point of seeing little reason to focus on more dangerous, less effective therapies when we already have a completely safe, simpler and so far more effective therapy according to conclusive controlled studies and patient testimony.
