Psychedelics, substances like LSD and psilocybin mushrooms that cause altered states of consciousness, often remind people of hippies in the 1960s. But more researchers are looking into their potential benefits for our well-being. Scientists say psychedelics – which are illegal for recreational use in Canada – could have massive implications on how we treat and heal from major mental health disorders like PTSD, depression and anxiety. Garvia speaks with Dr. Monnica Williams, clinical psychologist and associate professor at the University of Ottawa, where she is the co-director of the new master’s program in psychedelics and consciousness studies. They discuss the latest research and whether psychedelics will, and should, become mainstream.
