Gordon Wasson and Albert Hofmann. For the past four years, he has been coordinating the first academic course in psychedelic studies in France. Vincent Verroust is involved in the recognition of the therapeutic value of psychedelics in France. He took an active part in the creation of a working group for the resumption of clinical trials with psilocybin, gathering researchers from different public hospitals, and he assists various doctors and students in their discovery of the field. He is the founder and a board member of the French Psychedelic Society, a NGO of scientific mediation aimed at the general public, health professionals, journalists and politicians, which advocates for the reasoned integration of psychedelics in the society and which brings together activists as well as patients, doctors, and researchers from different disciplines.
