These athletes suffered life-changing injuries. Then, they turned to psychedelics.

A number of athletes – former and or current – are openly talking about using psychedelics to treat various conditions.

Daniel Carcillo wanted two things in life: to play hockey and to be a father. The Canadian started ice skating aged three and got his start in professional ice hockey as soon as he graduated high school. By 20 he’d broken into the NHL and over the next decade would play for the Philadelphia Flyers, New York Rangers and Los Angeles Kings. By 30, he was a two-time Stanley Cup winner with the Chicago Blackhawks and, in 2015, had retired from the sport, poised to enjoy retirement with his wife and three children, he says. By age 31, he was suicidal. After seven diagnosed concussions, Carcillo tells CNN that he was suffering from “dementia-like” symptoms, along with depression, anxiety and headaches, so much so that even a day out with his kids felt torturous.
