Hemp is helping.

Former Denver Broncos quarterback Jake Plummer says he is taking CBD oil, also known as cannabidiol oil, and it is easing the daily pain he suffered from a decade playing in the NFL.

He is one in a growing group of professional athletes who say they need safer and more natural ways to manage the pain that comes with their careers.

CBD is compound of cannabis that does not have THC. THC is the substance in marijuana that gives the feeling of euphoria or a "high."

Plummer is from Boise and went to Capital High before moving on to an NFL career. He is part of group of former and current NFL players asking the league to back research on CBD's effectiveness managing and preventing pain. They say the prescription drugs players take -- like opioids -- are far more dangerous and addictive.

"It is a real problem for players," Plummer said. "They may not be getting them in the locker room, but they can find those opioids everywhere, and they are terrible for you."

He says players reach for something when they are dealing with pain or injuries, and he feels a natural option is better.

"CBD grows in the earth. It is not addictive." Plummer said. "It helps your body instead of hurting it."

Eugene Monroe, a current player with the Baltimore Ravens, is helping pay for research into the cannabidoil out his own pocket. Plummer says a lot of players who have not come forward publicly are taking and benefiting from it.
