WNBA Moves to Drop Cannabis Testing in New Labor Agreement

The Women's National Basketball Association has agreed in principle to eliminate marijuana testing for players as part of a new collective bargaining agreement with its union, according to reports on the ongoing labor negotiations.

The policy shift would make the WNBA the latest major sports league to abandon cannabis restrictions for athletes. The league's decision comes after years of similar moves by the NBA, NFL, and Major League Baseball—all of which have dramatically scaled back or eliminated marijuana testing since 2020.

Details emerged from sources close to the CBA negotiations between the league and the Women's National Basketball Players Association. The agreement, which still requires formal ratification, represents a significant departure from the league's previous stance on cannabis use.

Following the Major Leagues

The numbers tell the story: In 2020, the NBA suspended random marijuana testing during its pandemic bubble season and never reinstated it. The NFL followed in 2021, raising its THC threshold tenfold and eliminating suspensions for positive tests. MLB removed cannabis from its banned substances list in 2019 for minor league players and later extended the policy to the majors.

These policy changes reflect broader shifts in both public opinion and state laws. With 38 states now allowing medical marijuana and 24 permitting adult-use cannabis, leagues have faced mounting pressure to reconsider policies that penalize athletes for using a substance that's legal in most of the country.

The WNBA's move is particularly notable given the league's history of strict testing protocols. Unlike some professional sports organizations that only tested with cause or during specific periods, the WNBA maintained year-round testing programs.

The Business Case

Market watchers note that cannabis policy changes in professional sports often correlate with broader business considerations. Several WNBA players have publicly advocated for cannabis law reform and medical marijuana access, including former All-Star Brittney Griner, whose detention in Russia over cannabis cartridges brought international attention to marijuana laws.

The timing also aligns with the league's recent growth trajectory. The WNBA secured a new media rights deal in 2024 worth $2.2 billion over 11 years—a massive increase from its previous $60 million annual agreement. That financial momentum may have given the players' union additional leverage in CBA negotiations.

For players, the policy change could mean more than just avoiding suspensions. Many athletes have cited cannabis as a preferred alternative to opioid painkillers for managing injuries and chronic pain—a concern that's particularly relevant in a high-contact sport like basketball.

What's Next

The CBA agreement still needs formal approval from both the league's board of governors and the players' union membership. If ratified, the new policy would likely take effect at the start of the next WNBA season.

The move could also influence other sports leagues still maintaining cannabis restrictions, particularly international organizations and college athletics programs. The NCAA modified its marijuana policies in 2022, raising THC thresholds and reducing penalties, but still maintains testing protocols that many consider outdated.

Whether the WNBA will go further—potentially allowing CBD sponsorships or partnerships with cannabis companies—remains unclear. But the initial policy change signals that women's professional basketball is ready to align with the evolving legal and cultural landscape around marijuana.
