"If you are after their psychotherapeutic effects, you would be wise to only take them under the supervision of a trained and experienced therapist who you respect and trust."
In what countries is this possible? Are these licensed therapists in the traditional sense, or something more like a shaman (for lack of a better name)?
It is possible in more countries than you might expect.
I strongly recommend reading The Secret Chief Revealed,[1] for a taste of how this has been done even in countries where prohibition rages, like the US.
You would also profit from following the links. reading up on, and perhaps contacting the various people and organizations listed in the Wikipedia article on Psychedelic Therapy.[2]
