In August of last year, as part of my year-long psychedelic-assisted therapy training program at CIIS, I volunteered at a legal psilocybin (the active ingredient in magic mushrooms) retreat center in Amsterdam called Synthesis. Of 4 facilitators, I was the only female facilitator, and one of 2 licensed therapists. 15 participants took a high dose of psilocybin during a 3-day retreat in a beautiful renovated church in the small beach town of Zandvoort.
