Former NFL tight end Martellus Bennett played for five different teams over the course his 10 seasons, so it's safe to assume he knows a thing or two about players in the league and their f-the-field habits.
Bennett, who retired this f-season, estimates that 89% NFL players smoke weed and not just because they enjoy getting stoned and playing video games. While that might be the case for some, Bennett says guys in the league smoke weed because it serves as an alternative to opioid painkillers and other prescription drugs.
Medical marijuana is legal in a number jurisdictions where NFL teams are based, including California and Colorado, but weed remains on the NFL's banned substance list and two positive tests will result in a suspension. That said, NFL players can only be tested for marijuana and other drugs from April through August and once they pass that test they're good for a full year.
In a documentary for Uninterrupted last year, former NBA player Al Harrington, who became a cannabis entrepreneur after his 16-year NBA career, estimated that as many as 70% athletes in major sports smoke weed.
