We sat in rapt attention while our patient, Jeff, described his brush with a suicide attempt. “I put the gun to my head and pulled the trigger . . . click. Nothing happened. The gun was empty. No bullets at all. I realized later that someone who cared about me more than I did about myself must have emptied the magazine.” Jeff, a former marine and firefighter, went on to recount how that experience served as a wake-up call. He needed to do something different, and fast. But what?

QUICK TAKE
  • Psychiatrists began testing whether psychedelic drugs, such as LSD and mescaline, could be used to treat mental health conditions in the mid-20th century.
  • Until the past several years, clinical trials of psychedelic drugs did not deliver meaningful results because they were too small and lacked proper controls.
  • Studies today are approaching the size and rigor required to finally show us whether psychedelics can treat conditions such as depression, anxiety, and PTSD.
