The NFL and NFLPA are formally discussing the possibility of raising the threshold for a positive marijuana test, according to Mike Garafolo of FOX Sports.
Under current policy, levels of THC, the active ingredient in marijuana, must be above 15 nanograms per milliliter to trigger a positive test. According to Garafolo and ProFootballTalk, Browns receiver Josh Gordon's "A" sample tested at 16 ng/ml.
Gordon was suspended by the league for one year.
The World Anti-Doping Agency, which oversees Olympic drug testing, raised its threshold for a positive test from 15 ng/ml to 150 ng/ml last summer.
