Doping Among Amateurs: MMA Shatters Records with the Highest Rate of Positive Tests

Doping in amateur sports is no longer just a shadow lurking behind professional arenas—it’s turning into a spotlight, especially in the world of MMA. Recent revelations point to a stunning surge in positive doping tests, with MMA racers smashing previous records by a mile. The Agence française de lutte contre le dopage (AFLD) revealed in its 2025 report that out of over 11,000 samples taken from amateur and emergent sports, a significant percentage relates to mixed martial arts (MMA). These disciplines, known for their demand in both endurance and physical strength, are seeing an alarming rise in substance abuse, casting serious doubts on the integrity of the sport at grassroots levels. In fact, MMA’s ratio of positive tests to total samples stands massively higher than many other sports, an unsettling trend that raises urgent questions about anti-doping effectiveness and performance enhancement tactics outside the professional spotlight.

While rugby and football have been historically scrutinized for doping issues—check out the latest dynamics via Rugby World Cup 2023 data—the amateur MMA circle is eclipsing others with this unprecedented rate of positive tests. The issues stretch beyond just the sport; they reveal loopholes in monitoring emerging fields like crossfit and hyrox, which share a culture heavily influenced by muscle-building and supplementation, often blurring the lines between legal nutrition and banned substances.

Record Rates of Positive Tests in Amateur MMA Challenge Sports Integrity

The latest statistics from AFLD reveal 181 doping controls in MMA amateurs, with 12 recorded positive tests—a ratio that towers over other disciplines in the amateur arena. Such numbers place MMA at the forefront of the doping debate among amateurs, forcing stakeholders to rethink anti-doping strategies beyond elite competitions. This landscape shift is echoed globally as agencies like the International Mixed Martial Arts Federation (IMMAF) partner with the International Testing Agency (ITA) to bolster screening and detection, referencing the critical need for rigorous controls both in-competition and out-of-competition.

The Growing Challenge of Drug Use in Emerging Sports Scenes

What sets sports like MMA, crossfit, and hyrox apart is their integration of strength, endurance, and the rising culture of supplementation. The AFLD’s report noted an increase in doping control focus on amateurs, with controls for non-national or international level athletes rising to nearly 30% in 2026. This reveals a strategic pivot—hitting harder where it previously lacked muscle. As BĂ©atrice Bourgeois of AFLD pointed out, doping is no longer confined to professional competition; instead, it’s hiding “everywhere,” often rationalized as a harmless enhancement or aesthetic aid.

The types of substances flagged are telling: anabolic agents top the list at 23%, followed by cannabinoids (22%), diuretics and masking agents (21%), and stimulants (17%). This range highlights how varied and accessible doping substances have become, creating a dangerous playground for amateurs craving a competitive edge or body transformations.

Widening the Anti-Doping Net: How AFLD is Targeting Amateur Sports and Emerging Disciplines

With access to doping substances reportedly “extremely easy,” authorities are deepening their efforts in amateur sports, including MMA’s most vulnerable platforms. The AFLD’s intensified attention shines a light on sports historically less monitored, such as crossfit and hyrox, where doping threats merge with the culture of dietary supplements and muscle enhancement. This evolution in oversight seeks to maintain sports integrity and stall the creeping normalization of performance enhancement through illicit means.

Moreover, as cases pile up with sanctions sometimes extending four years or more, there’s an inherent call to arms for better education, testing methods, and cultural change within amateur ranks. This is a battle not just against substances, but against an attitude that undermines fair competition at all levels.

For those tracking similar challenges in other sports, the ongoing sanctions in rugby remind us of the broader landscape.
