The NFL adjusted their marijuana policy earlier this year, raising the threshold of testing positive from 15 nanograms to 35 nanograms of spent THC carboxy for every milliliter of pee. While the increase no-doubt helps some athletes who prefer to use cannabis instead of pharmaceutical drugs to treat pain, the league falls far behind other sports when it comes to cannabis tolerance.
The threshold does make it easier to toke up during the off-season, but the increase of 20 nanograms doesn’t equate to a free ticket to get high all the time.
