Not the OP, but he’s not joking — it’s an area with an increasing amount of interest and research, although obviously tremendously hampered by the legal issues. I don’t have any links, but you can find plenty on google.

There are also studies using it to treat PTSD in veterans.

MDMA was originally used as a couples therapy drug in the early 20th century. It is a heart opening medicine that gently removes your ego. It is very powerful and beautiful. All about set and setting.

I don't have links (sorry) but a few prominent people in the psychedelics-for-therapy crowd often share anecdotes about these drugs helping people to shed ego, communicate better, and generally build bonds better. There are real accounts of this, but many if not all are anecdotal due to how limited data is and how informal data capture is.

A great place to look is Tim Ferriss' podcast episodes about psychedelic therapy. He has two I can think of, and one has a few great anecdotes. From him you'll find many others. Gabor Maté is a good one to check out. He uses psychedelics extensively in therapy and has for quite some time.

One woman I listened to (I believe on Tim's podcast) detailed how her and her husband would take MDMA (I believe) every year or so and talk things out. Whether things were good or bad. She describes herself as the last kind of person you'd expect to see taking illegal drugs, but here she is, and she believes it has made her marriage far better than it would have been without them.

There are countless similar stories.
