I'm not saying there's anything wrong with this method of therapy but it reminds me of the time a relative went to a licensed therapist who did past life regression hypnotism. (And it's well documentation that there is something wrong with that!)

A licensed therapist who does psychedelics is someone outside the norms of society while at the same time carrying a license that carries the implicit promise of following society's rules. It just strikes me as "weird" to seek that out.
