Ravens tackle Eugene Monroe donated the remaining money needed to fund studies on Cannabinoids and its potential benefits to NFL players.

Monroe, the only active player involved in the campaign, ” When the Bright Lights Fade,” earlier had contributed $10,000 to the cause. On Thursday, he contributed another estimated $60,000 to the studies.

The campaign, led by Colorado hemp producer CW Botanicals and its partnering nonprofit the Realm of Caring, plans to see if Cannabinoids, a nonpsychoactive compound from cannabis, is a viable alternative to the potent prescription painkillers players currently receive by teams, and to eventually examine its potential benefits in alleviating symptoms of concussions and chronic traumatic encephalopathy (CTE).
