Marijuana could soon be accepted medicine in the NFL.

During an a recent interview with ESPN, National Football League Commissioner Roger Goodell indicated that the future of medicine in the NFL could eventually lend itself to an amendment of the league’s drug policies, allowing players the use of medical marijuana.

"I don't know what's going to develop as far as the next opportunity for medicine to evolve and help either deal with pain or help deal with injuries, but we will continue to support the evolution of medicine," he said.

Regardless of marijuana’s newfound legal status in many states across the nation, many sports insiders say the league is not likely to consider lifting its ban on the substance until at least 2021 -- when the league’s collective bargaining agreement is set to expire, giving players the opportunity to renegotiate policy.

Yet, recent statements by Goodell, reportedly the first made on behalf of the NFL in regards to marijuana since legalization of the leaf occurred in Colorado and Washington in 2012, suggest the nation’s most highly revered sports league is at least engaged in progressive thinking.

Past reports seemed to point towards league officials remaining steadfast in their efforts to keep marijuana out of football. "The NFL's policy is collectively bargained and will continue to apply in the same manner it has for decades," said league representative Greg Aiello. "Marijuana remains prohibited under the NFL substance abuse program."

However, sports experts say the collective bargaining agreement will not keep the league from loosening its policies surrounding marijuana if or when they decide it is appropriate to do so. According to Pro Football Talk, the current ban is only associated with “illegal use” of marijuana, which could make it relatively easy for the league to give players a free pass in the case of medical marijuana.
