It depends what you're going for. Maps.org's research with MDMA-assisted psychotherapy for PTSD had incredible results. If you do it recreationally with a partner you'll become physical-intimate with, you'll be able to distract yourself away from yourself more - if doing it solo with guidance and support of someone else, you'll more be able to focus and process on thoughts/feelings/memories that come up. There's benefit and space for both.
