Thanks, ChickenNoodleSoup, for the detailed and thoughtful post. I've had a fair amount of psychedelic experiences in my life as well that I never discussed with a therapist. The last T I saw had an interest in this and told me that he also explored quite a bit when he was younger, but I never talked with him about mine too much as most happened long before I saw him, and a bit after stopping therapy. I agree that a conventional one-hour therapy session may not be appropriate for an active experience but, as you say, could be used for integration.

I'm interested in this because there is so much research going on in this area these days and a lot of initiatives to develop clinical settings, practice and follow-up for it legally. They definitely don't aim to be like a normal psychotherapy session, including extended time, in some cases, they have two therapists assisting instead of just one, and much more emphasis in setting. There are also more unorthodox approaches, e.g. when the therapist would also take the drug with the client, so it is not a one-sided experience (I believe those Ts don't run sessions like that too often, or at least I would hope!). I did a retreat once with a group and a mix of scientific/clinical and shamanic practitioners, and the retreat center also offered follow-up integration work afterward in private, but that's not exactly psychotherapy. I really liked the group aspect though, doing it with multiple people and having varied perspectives. Also liked that they required a thorough physical before attending the retreat and attestation from a doctor that there wouldn't be any known physical or psychiatric contraindications.
