No banned substances found at Milan-Cortina Winter Olympics for first time in 28 years

The 2026 Milan-Cortina Winter Olympics have achieved a significant milestone in Olympic anti-doping history: no athlete has tested positive for banned substances during the Games, marking the first such occurrence in 28 years.

Anti-doping officials collected more than 3,000 samples from nearly 2,000 athletes throughout February's Winter Games in Italy, with zero anti-doping rule violations reported during the competition period. This achievement represents the first Winter Olympics since Nagano 1998 to record no positive tests during the event itself.

The clean slate stands in stark contrast to previous Olympic cycles. Following the 2012 London Olympics, 31 medals were eventually withdrawn and 46 others reallocated due to positive doping tests discovered through retrospective analysis. The situation became even more complex after the McLaren report, commissioned by the World Anti-Doping Agency (WADA), exposed Russia's state-sponsored doping program operating from 2011 to 2015, affecting both the 2012 Summer Olympics and 2014 Winter Olympics.

However, anti-doping experts caution against declaring these Games definitively "clean." Olympic samples are preserved for 10 years to enable retrospective testing as new detection methods develop, meaning potential violations could still emerge in the future.

Enhanced Pre-Competition Testing Strategy

The absence of positive tests during Milan-Cortina reflects a fundamental shift in anti-doping strategy, with significantly increased testing in the months preceding major competitions.

The International Testing Agency (ITA) confirmed that 92% of Olympic participants underwent at least one test during the six months prior to the Games. Benjamin Cohen, the ITA's director general, described this as "our most extensive program ever implemented."

This comprehensive pre-Games approach did yield one notable case. Italian biathlete Rebecca Passler received a provisional suspension from Italy's anti-doping agency after testing positive for "Letrozole metabolite bis, methanol" on February 2, just four days before competition began. Letrozole, primarily used to treat breast cancer by reducing estrogen levels, is prohibited in sports.

Following an appeal, Passler was cleared to compete in the Games, though WADA indicated this was a provisional decision pending a formal hearing by Italy's National Anti-Doping Organisation (NADO).

"The approach has fundamentally changed," Cohen explained to BBC Sport. "Previously, we only tested athletes upon arrival at the Olympic Games. Today's system involves continuous monitoring throughout an extended period, particularly during the critical qualification phase when athletes are most motivated to gain advantages. This wasn't standard practice two decades ago, and athletes now understand this reality, which likely contributes to the declining positive tests during Olympic competition."

Lessons from Past Injustices

The enhanced testing protocols aim to prevent situations like the one experienced by Britain's four-man bobsled team at Sochi 2014. John Jackson, Bruce Tasker, Stuart Benson, and Joel Fearon initially finished fifth, behind two Russian crews later disqualified for doping violations.

The British team finally received their bronze medals nearly six years later at a Team GB celebration in 2019—a bittersweet moment that highlighted the broader consequences of delayed justice in anti-doping cases.

"The question of whether I feel like an Olympic medallist remains complex," Jackson reflected to BBC Sport. "We never experienced that podium moment that defines Olympic achievement. Beyond personal recognition, we missed crucial funding opportunities for our sport and potential sponsorship deals. More significantly, other athletes may have been forced to retire because they couldn't meet funding benchmarks due to these delayed results. The ripple effects extend far beyond individual competitors."

Calls for Stronger Deterrents

Despite acknowledging the progress made by WADA and the ITA, Jackson believes current anti-doping measures remain insufficient to eliminate cheating entirely. He advocates for more severe consequences to create effective deterrents.

"Lifetime bans should be the standard," Jackson argued. "Great Britain previously implemented such policies, and I believe only through significantly more severe consequences can we hope to eradicate doping completely. The current system still allows determined cheaters to stay ahead of detection methods."

The Milan-Cortina results suggest that enhanced pre-competition testing and improved detection capabilities are making a measurable impact on Olympic integrity. However, the ongoing preservation of samples for retrospective analysis serves as a reminder that the final assessment of these Games' cleanliness may not be possible for years to come.
