Performance-enhancement: A common perception of marijuana is that its use impairs physical activity, including exercise performance. While the effects of marijuana can decrease hand-eye coordination and distort spatial perception, there are other effects that can be performance enhancing for some athletes and sport disciplines. Cannabis can cause muscle relaxation and reduce pain during post-workout recovery. It can also decrease anxiety and tension, resulting in better sport performance under pressure. In addition, cannabis can increase focus and risk-taking behaviors, allowing athletes to forget bad falls or previous trauma in sport, and push themselves past those fears in competition.
