Psychedelic-assisted therapy is fast becoming a promising area of mental health and spiritual healing around the globe. As society begins to integrate psychedelics into health care and wellness communities, the need for educated and trained professionals is expanded. California Institute of Integral Studies (CIIS) has been a leader in the field of consciousness studies and psychology for more than 55 years. In 2015, our impact and prominence expanded when we created the first-ever university-affiliated Psychedelic-Assisted Therapies and Research Certificate Program.
