Most races in their rules state some sort of zero-tolerance policy. Id be very surprised if the Georgia Death Race didn't have something like the below as part of their rules. Not that I really care about what happened, but if the Georgia Death race rules stated something like the below and weed was smoked its very possible that he could've been in violation. But as there were no tests we wont know.
The Western States Endurance Run has a zero-tolerance policy regarding the use of performance enhancing drugs (PEDs). Any athlete who has been determined to have violated anti-doping rules or policies, whether enforced by the International Association of Athletics Federations (
IAAF), the World Anti-Doping Agency (
WADA), U.S. Anti-Doping Agency (
USADA), or any other national sports federation is ineligible for entry into the Western States Endurance Run. The Western States Endurance Run reserves the right to conduct pre and post-competition testing for any and all performance-enhancing drugs (PEDs) listed on the current WADA Prohibited List. Any athlete who refuses to submit to anti-doping controls, if selected for testing, shall be disqualified and subject to a lifetime ban from the Western States Endurance Run.
