Seven first responders from across the US traveled to Mexico seeking a therapy they hoped would transform their lives. Over the course of three days a team would guide them through ceremonies with psilocybin, the psychedelic 5-MeO-DMT and tobacco. The retreat ... offered a chance at healing that had eluded the first responders through years of counseling, medication and meditation. The US is in the midst of a mental health crisis, and it is particularly acute among first responders including police, firefighters and paramedics " who are at greater risk of post-traumatic stress disorder (PTSD), depression and suicide. A wide body of peer-reviewed research from scientists across the world has found that supervised use of psychedelics, such as psilocybin, can be a powerful tool to treat symptoms of depression, PTSD and other conditions. During the days-long event, [Angela Graham-Houweling] took psilocybin and later five doses of 5-MeO-DMT, a powerful psychedelic. The ... session was grueling, she said, describing it as one of the most difficult things she'd ever done. She felt a sense of tranquility and a less frantic, reactive brain. "Two weeks [later] I still was able to be calm with [my son] and everyone. I remember thinking: 'Wow, is this how everyone else gets to feel all the time?'" That sense of peace and the tools Graham-Houweling gained during the retreat, such as practicing mindfulness and staying aware of her emotional state, changed her. She felt better.
