I'm not sure it's completely a good idea. If I had a local access to clean legal ketamine, I know I would be in deep trouble. Dealing with un-reliable shaddy people helped me to get away from ket. Maybe make ket infusions under medical supervision for suicidal people more available and affordable?
For the MDMA, I did so much I lost the magic and it turned into nausea and anxious come-ups. But I'm not against the idea of legalizing the use under the supervision of a therapist.
But I'm totally for having more access to medecines like iboga, aya, bufo, cacti and kambo, with providers checked and having medical knowledge.
And, make it affordable, not just a "in" thing for the richs. All classes in society should have a chance to heal.
