Having written about endocannabinoids as the likely source of runners high, I wanted to draw people’s attention to this report, which talks (in the middle third) about the use of exogenous cannabinoids by athletes.
If runner’s high is not enough, why do people exercise on THC, the active ingredient in cannabis? It is not unusual for athletes, like other social groups that follow common routines, to combine popular lifestyle activities like alcohol (beer after racing) and food consumption (pre-race pasta parties), with others in the clan. The same appears true of cannabis use, enhancing leisure and social activities such as getting together for a run or race.

Even the first bit (on nicotine as a possible performance-enhancing drug) is interesting, with an appropriate emphasis on tobacco’s dangers. The bit on marijuana, viewed largely through the lens of its possible beneficial effects both during and after exercise, made for a nice contrast.
