From my experience of dealing with people that I have thought to be sociopaths when they describe their experiences on MDMA they usually describe them as feeling really good and feeling really good about themselves but without developing or expanding their empathetic connection to others.
This. I've had two ex-partners who fall somewhere down that spectrum (one diagnosed) and they both really enjoyed MDMA (one having abused it in the past and one bordering on unhealthy regularity).
They just enjoy feeling really good.
My most recent ex also really enjoyed psychedelics, but as far as I could tell she had qualitatively very different experiences from me - not so much of the psychedelic/mystical/connecting aspects and more of recreational enjoyment and to some limited extent self-exploration. Her deepest realization was that she appreciated hanging out with her childhood friend. She never had a bad or dark trip or any of the anxiety.
I think it's a mistake to believe that these things affect different psyches similarly.
