Altered states: Can LSD contribute to mental health?

Faith Salie reports on how LSD and “magic mushrooms” are being studied for their ability to help patients conquer anxiety and depression without the psychedelia long associated with mind-altering drugs. Salie talks with author Ayelet Waldman, who microdosed LSD and overcame a deep depression, and with NYU professor Tony Bossis, who conducted a clinical trial of cancer patients treated for depression with a one-time dose of the psychedelic Psilocybin.
