USA - Cannabis oil to prevent frostbite in sled dogs in Alaska races

According to The Anchorage Daily News, Lance Mackey of Fairbanks, a well-known musher in the Iditarod Trail section of Alaska, gives his dogs CBD oil during the race, which he says improves their recovery time from prone to frostbite. Mackey told the newspaper that Chief Veterinary Officer Stuart Nelson asked him not to give CBD oil to his dogs, but he refused because CBD oil is not on the Iditarod’s prohibited list of substances.
CBD is a non-intoxicating molecule found in hemp and marijuana. Both are cannabis plants, but only marijuana has enough THC to give consumers an intoxicating effect. The CBD pet market has grown, with some significant health benefits in treating seizures and managing pain, but the federal government has yet to establish regulation for the substance.
Mackey is a cancer survivor who has used medical marijuana since 2007 during his four-year successful battle with the disease.
The Iditarod banned marijuana use by mushers in 2010, a ban Mackey says was motivated by envy over his championship successes. Mackey won his fourth championship in 2011, after marijuana was banned, in a nearly 1,000-mile (1,609-kilometer) race through Alaska.
