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."
