Four-time Iditarod champion Lance Mackey found himself at the center of a cannabis controversy after the Anchorage Daily News reported that Mackey is giving his dogs CBD oil, which he says improves their recovery time.

Mackey, who is currently racing in fifth place, told the newspaper the race’s head veterinarian, Stuart Nelson, asked him not to give CBD oil to his dogs, but Mackey declined because CBD oil is not among the list of banned substances in the Iditarod rule book.

Short for cannabidiol, CBD is a non-intoxicating molecule found in hemp and marijuana. Both are cannabis plants, but only marijuana has enough of the compound THC to get users high.
