Report: NFL offers to study marijuana for pain management with NFLPA

The NFL has formally reached out to the NFLPA to offer to jointly study marijuana's potential use as a pain management drug, Mark Maske of The Washington Post reports.

The NFL has taken a hard-line stance against marijuana over the years, including stricter testing thresholds and longer suspensions for positive tests than exist in other sports.

Now, a source told Maske that the NFL has written a letter to the players' union asking if there's interest in mutually working on research into marijuana's potential to manage chronic and acute pain.

Previously, the union has pushed for the NFL to take a less punitive approach to marijuana use among players, and has suggested the union is already involved in research regarding marijuana as a pain relief method.
