Cannabis in Professional Sports: How the NFL, NBA, and UFC Changed the Game on Marijuana Policy

In 1998, the NFL suspended running back Ricky Williams for an entire season over marijuana use. The message was unambiguous: cannabis and professional athletics were incompatible, and athletes who disagreed would pay with their careers. Williams became a cautionary tale, his extraordinary talent permanently asterisked by what the league treated as a character flaw.

In 2026, the landscape is unrecognizable. The NFL no longer suspends players for positive cannabis tests. The NBA has removed marijuana from its prohibited substances list entirely. The UFC rescinded cannabis-related sanctions. MLB never tests for it during the offseason and eliminated suspensions for positive in-season tests. Multiple active athletes across every major professional sport publicly use cannabis products for recovery, sleep, and pain management — and endorse cannabis brands with their names and faces.

The transformation has been swift, incomplete, and more complicated than the simple narrative of progress suggests. This is the story of how it happened, who made it happen, and what friction remains.

The NFL: From Zero Tolerance to Quiet Acceptance

The NFL’s relationship with cannabis has historically been defined by a contradiction: a league that produces catastrophic physical injuries at industrial scale while prohibiting the substance many of its players considered the most effective and least harmful tool for managing the resulting pain.

The turning point came with the 2020 collective bargaining agreement, negotiated between the NFL Players Association and league ownership. The CBA raised the THC threshold for a positive test from 35 nanograms per milliliter to 150 ng/mL — a level so high that only recent, heavy use would trigger it. Testing was restricted to a two-week window at the start of training camp, effectively creating an eleven-month period during which players could use cannabis without consequence. Suspensions for positive tests were eliminated entirely, replaced with mandatory clinical evaluation and, for repeated positives, treatment referrals.

By 2024, the policy had effectively decriminalized cannabis within the league without technically legalizing it. Players noticed. In anonymous surveys conducted by the NFLPA, reported cannabis use among active players rose from an estimated 50-60% pre-CBA to over 70% post-CBA. The sky did not fall. Performance metrics did not decline. The only measurable change was a reduction in opioid prescriptions among team medical staffs — a development that aligned with broader research on cannabis as an opioid alternative.

Former players have been more vocal than active ones. Ricky Williams himself became a cannabis entrepreneur, launching a line of cannabis wellness products. Kyle Turley, the former offensive lineman who has spoken extensively about CTE and chronic pain, credits cannabis with saving his life after years of opioid dependence. Marvin Washington, a former defensive end, co-founded a CBD company and has lobbied Congress for federal reform. Eugene Monroe, who retired from the Baltimore Ravens in 2016 partly to advocate for cannabis research, has become one of the most prominent athlete-advocates in the reform movement.

Among active players, the stigma has not fully dissolved. Most current NFL athletes who use cannabis do so quietly. Endorsement deals from non-cannabis sponsors still include morality clauses that could be triggered by public cannabis advocacy, and the league’s broadcast partners remain cautious about association. The policy has changed; the culture is still catching up.

The NBA: The League That Led

The NBA moved faster and further than any other major professional league. In 2020, the league and the National Basketball Players Association agreed to suspend random marijuana testing during the pandemic-era bubble season. That suspension was never formally reinstated. In 2023, the NBA and NBPA jointly announced that marijuana would be permanently removed from the league’s drug testing program.

The decision reflected a practical reality: marijuana use among NBA players was widespread, consequences were creating PR problems for the league without providing any competitive integrity benefit, and the racial dynamics of enforcement — Black athletes being punished for using a substance that was legal and celebrated in many of the cities where they played — had become untenable.

Former NBA players Al Harrington and Cliff Robinson (before his passing in 2020) were among the earliest athlete-entrepreneurs in cannabis. Harrington’s company, Viola, became one of the most recognized Black-owned cannabis brands in the country, and his advocacy helped shift the conversation among active players and league executives alike.

Current players are notably more open than their NFL counterparts. Multiple active NBA athletes have disclosed cannabis use in interviews and podcasts without consequence. Several have invested in cannabis companies, and at least two have appeared in cannabis brand campaigns — something that would have been career-ending a decade ago.

The NBA’s approach has influenced other basketball organizations. FIBA, the international basketball governing body, raised its THC threshold in 2024, and the BIG3 league has never tested for cannabis.

The UFC and Combat Sports: Where Recovery Demands Are Highest

Combat sports occupy a unique position in the cannabis-athletics conversation because the physical toll is so extreme. UFC fighters regularly compete through injuries that would sideline athletes in other sports, and the recovery demands between fights — which can occur every few months — are immense.

The UFC does not directly control drug testing for its athletes; that function is handled by the United States Anti-Doping Agency (USADA) under a partnership agreement. In 2021, USADA announced that it would no longer penalize UFC fighters for positive marijuana tests unless evidence indicated use during competition — a standard that effectively limited enforcement to fighters who were actively high during a fight, which is vanishingly rare.

Nate Diaz brought cannabis into the UFC mainstream when he vaped CBD at a post-fight press conference in 2016, drawing a reprimand from USADA that was later reduced. The moment was iconic precisely because of its casualness — Diaz treated cannabis use as unremarkable, and the public largely agreed. By 2026, Diaz’s nonchalance looks prescient rather than rebellious.

Current UFC athletes are among the most openly pro-cannabis in any sport. Fighters regularly discuss using cannabis for recovery, sleep, and anxiety management before fights. The physical logic is straightforward: cannabis reduces inflammation, addresses chronic pain without the liver and kidney damage associated with long-term NSAID use, and improves sleep quality during intense training camps — all benefits consistent with what the cannabis exercise research literature has documented.

MLB and Other Leagues

Major League Baseball removed marijuana from its list of banned substances for minor league players in 2021, a significant change because minor leaguers had previously been subject to suspensions (while major leaguers, under a separate agreement, were not tested). The current policy across all levels of organized baseball treats marijuana identically to alcohol: legal, not tested for, and subject to treatment referral only if a player self-identifies a substance use problem.

The NHL has never tested for marijuana. Hockey’s omission from this conversation is partly by design — the league’s collective bargaining agreement explicitly limits drug testing to performance-enhancing substances — and partly cultural. Hockey players have historically been among the most discreet professional athletes about off-field behavior of any kind.

Professional soccer presents a more complex picture. MLS follows WADA (World Anti-Doping Agency) guidelines, which still list THC as a prohibited substance in-competition. However, the threshold was raised to 150 ng/mL in 2013, and enforcement has been minimal. International players face stricter scrutiny, particularly those competing in FIFA-sanctioned events where a positive test could result in a ban from World Cup or Champions League competition.

CBD Recovery Products: The Mainstream Bridge

While THC-containing cannabis remains culturally complicated in professional sports, CBD has achieved near-total acceptance. CBD recovery products — topicals, tinctures, capsules, and beverages — are now standard equipment in training rooms across every major professional league.

This shift was enabled by the 2018 Farm Bill, which legalized hemp-derived CBD at the federal level, and by WADA’s 2018 decision to remove CBD from its prohibited substances list. The distinction between CBD and THC gave leagues and athletes a way to embrace cannabis-derived recovery tools without confronting the political baggage of marijuana itself.

The product category has matured significantly. Early CBD sports products were often poorly formulated, with inconsistent dosing and dubious bioavailability. The current generation includes transdermal patches that deliver sustained CBD release over 8-12 hours, nano-emulsion formulations with dramatically improved absorption, and combination products that pair CBD with other anti-inflammatory compounds like curcumin and boswellia.

Several athlete-founded CBD brands have achieved mainstream visibility. Rob Gronkowski’s partnership with CBDMedic (later Cbdmd), Megan Rapinoe’s involvement with Mendi, and Bubba Watson’s CBD endorsements brought the category to audiences far beyond the traditional cannabis consumer base.

The Remaining Stigma

Despite the policy transformations, cannabis stigma in professional sports has not disappeared — it has become more selective and more subtle.

Sponsorship dynamics. Major non-cannabis sponsors (automotive, financial services, apparel) remain reluctant to associate their brands with athletes who publicly advocate for cannabis. This creates a financial incentive for active athletes to stay quiet even in leagues that no longer penalize use. The economic pressure is real: a single major endorsement deal can exceed a mid-tier athlete’s playing contract.

Coaching and front office culture. While players have largely moved past cannabis stigma, coaching staffs and front offices — populated by an older demographic — have been slower to adjust. Anonymous reports from multiple leagues describe situations where cannabis use, while technically permitted, is quietly factored into character assessments during contract and draft evaluations.

International competition. Athletes who compete in both domestic professional leagues and international events governed by WADA face a fragmented regulatory landscape. An NBA player who uses cannabis legally during the regular season must abstain before representing the United States in the Olympics or FIBA World Cup. This dual standard creates confusion and risk, as Brittney Griner’s detention in Russia — while not a WADA case — painfully illustrated.

The racial dimension. The legalization of cannabis in professional sports has occurred alongside persistent racial disparities in cannabis enforcement in broader society. The irony is not lost on athletes or advocates: predominantly Black and Brown professional athletes were punished for years for using the same substance that is now generating billions in legal revenue, largely for white-owned companies. This tension connects to the broader cannabis social equity conversation happening across the industry.

What Comes Next

The trajectory is clear, even if the timeline is not. Full normalization of cannabis in professional sports will likely follow the same path as alcohol: technically permitted, commercially integrated, and socially unremarkable for adults who use responsibly. The remaining barriers are cultural and commercial rather than regulatory. The leagues have done their part. The athletes have done more than their part. The sponsors, broadcasters, and front offices are the holdouts, and economics will eventually bring them along.

For the millions of recreational athletes and fitness enthusiasts who take cues from the professionals they watch, the message is already landing. Cannabis is part of the recovery toolkit now. The cannabis and fitness guide landscape reflects this shift. What was once a secret has become a strategy, and professional sports — the last cultural institution you would have expected to embrace it — turned out to be the catalyst.
