I don't have PTSD, but I do have depression, anxiety, and unofficially, I probably lie on the autism spectrum.
Can I prove anything with my sample size of one with plenty of confounding variables? Of course not. But does it make me personally believe the studies that have indicated it can be a good treatment for mental disorders are valuable and true? Absolutely.
I strongly believe that safe, controlled administration of pure, clean MDMA is something every adult should have the opportunity to legally try, especially in cases where evidence supports benefit to a psychological condition. And more research should happen. The mindset of "all drugs are heroin" has got to go.
I'm not advocating people taking pills they bought on the street, but I do support legalising of drugs that, when pure and controlled in dose like pharmaceutical medicine, don't cause a significant number of deaths or violence - such as MDMA and marijuana.
I strongly support destigmatization of drugs and more research, and the breakdown of the black and white border of "the government decides which drugs are good and which drugs are evil and everything else is for violent crackheads."
I'll probably do it again. I just wish there were more studies so I could know how often is safe and optimal to take it.
(For the pedants: the positive test for the presence of MDMA does not prove that the substance isn't adulterated, but it's certainly better than a negative result.)
In my experience I had blue mondays way worse on my first 3 times, and then I've got to the point where I am no longer blue on the days after. That would be my 6 times over a 5 year period.
The 6 weeks number is more a rule of thumb. For some it's longer, for others shorter. In the beginning, it may not matter, but if you browse drug forums for a while, you'll see the pattern 'don't do it too often' emerge.
6 times over a 5 year period looks quite safe. I have some friends who have used MDMA more than that and some of them started to have longer 'sad' or 'depressed' periods, sometimes stretching into months. Again, it would be great if there was an authoritative manual for all of this, but I don't think something like that exists.
While I think MDMA-assisted psychotherapy is extremely promising, MDMA itself is definitely not risk free (especially when obtained from unregulated and adulterated sources); and various complications can and do occur.
Were you alone or with friends? Home or out?
Ironically enough, heroin is one of the few of these banned substances that is actually approved normally for medical use [0] (Not in the USA actually, according to this reference).
The name "Heroin" itself, was a trademark of the Bayer corporation [1]
The Phase 2 trials have showed that 63% no longer meets the criteria of PTSD 2 months after the last MDMA session, as compared to 25% for the placebo.
As for how long your results may last, another study conducted by MAPS after 2.5 years found that the effects have generally still persisted.
