The NFL sent a letter to the NFL Players Association this week offering to work hand in hand on a study that looks into the use of marijuana as a pain-management tool. According to the Washington Post, the NFLPA is already conducting its own study and has not yet responded to the NFL's offer.
"We look forward to working with the Players Association on all issues involving the health and safety of our players," Joe Lockhart, the NFL's executive vice president of communications, said in a statement.
This, of course, is not nearly the first time the issue of marijuana as a pain reliever has come up for the NFL.
