Sadly, the safest bet you can make in NFL football isn't which team will win on any given Sunday. It's how many will be diagnosed with degenerative brain disorders stemming from injuries sustained in the game.

"According to a recent study conducted by the Department of Veterans Affairs and Boston University shows 96% of former NFL players suffer from the neurodegenerative disease known as chronic traumatic encephalopathy (CTE). CTE is widely believed to stem from repetitive trauma to the head and can lead to conditions such as memory loss, depression and dementia."

That quote appears at the beginning of the short documentary film "When the Bright Lights Fade" (2016). Narrated by Grammy Award winning musician and marijuana advocate Melissa Etheridge, the film features former quarterback Jake Plummer, running back/fullback Reuben Droughns, wide receiver/tight end Nate Jackson and others sharing their stories in hopes of encouraging the NFL and the NFLPA and NFL fans to support research into cannabis as a potential treatment for CTE.

The film was produced by CW Botanicals - makers of Charlotte's Web hemp extract - and in association with The Realm of Caring - a Colorado-based research group that is planning to team up with Johns Hopkins Hopkins University and other research institutions to test the effectiveness of cannabis in treating CTE.
