MDMA will probably be regularly used for psycholytic therapy within the next decade and likely see legalization in the same cities that're legalizing psychedelics right now. It has a lot of potential for treating PTSD, trauma and anxiety, and most of the danger is around impure pressings, exhaustion, water toxicity, etc.

Personally, it helped me a lot with learning how to open up to and trust people. I used to think I was an introvert, but I really just had severe social anxiety from a difficult upbringing.
