Study: Marijuana High linked to Runners High.
It seems the common theory that "runner's high" is due to increased endorphin levels may not be entirely true. Scientists in Georgia and California discovered high levels of anandamide in people who ran or cycled at a moderate or intense pace for about an hour. Anandamide is a cannibinoid- the same as THC, the psychoactive substance found in marijuana. What is interesting is that it is believed that the body releases cannibinoids to help it cope with the prolonged stress and pain of moderate or intense exercise. It seems that the medical advantages of THC and other cannibinoids are being consistently proven in the medical field. Of course, if one has the strength to exercise at an intense level, it would surely be the healthiest and most natural way to help relieve pain and stress.
