Baltimore Ravens offensive tackle Eugene Monroe urged NFL players to donate to marijuana research on Tuesday morning, a day after an NFL official acknowledged a link between football-related head trauma and chronic traumatic encephalopathy.

Monroe tackled the issue on Twitter:

If 100 players gave 1,000 for research. Or 200 gave 500, We can get Realm of Carings initiative in conjunction with John Hopkins U started — Eugene Monroe (@TheSeventyFifth) March 15, 2016

Many of you will triple that expense this weekend in Miami — Eugene Monroe (@TheSeventyFifth) March 15, 2016

Realm of Caring Foundation is an organization committed to researching the health benefits of marijuana and educating the public about this form of therapy. Monroe told CNN last week that the NFL needs to change its stance on marijuana and take a look at the drug's possible benefits as it relates to pain relief and possibly concussions.

Monroe tweeted that he has donated $10,000 to marijuana research and will give more if "nobody steps up."

Let's put our hard earned money towards our health and wellness futures — Eugene Monroe (@TheSeventyFifth) March 15, 2016

If I'm a fan, I'm pissed at the time I wasted listening to Goodell lie to me at the Super Bowl. As a player I sure am — Eugene Monroe (@TheSeventyFifth) March 15, 2016

Monroe sent out 37 tweets over a two-hour period Tuesday morning on topics ranging from marijuana research to the NFL official acknowledging a connection between head trauma and brain disorders. For years, NFL commissioner Roger Goodell and other league representatives have avoided taking a position, repeating that the league would let the medical community decide.
