Steven Cantwell Receives Second Doping Violation
USADA imposed a 10-year ban on para-snowboarder Steven Cantwell for a second doping violation after he refused to provide a sample during an out-of-competition test in April 2026.
Steven Cantwell of Dillon, Colo., a para-snowboarder, has been handed a 10-year ineligibility period by the U.S. Anti-Doping Agency (USADA) for his second anti-doping rule violation. The sanction follows Cantwell’s refusal to provide a sample during an out-of-competition test on April 30, 2026, which constitutes a violation under the World Anti-Doping Code and related policies. The standard penalty for a first refusal is four years, but Cantwell’s prior violation—stemming from the presence of a prohibited substance in a 2025 sample—resulted in an increased sanction between eight and 10 years.
Cantwell’s 10-year ban will begin after the completion of his six-year suspension for his first violation, which was imposed for the presence of dehydrochlormethyltestosterone (DHCMT) and his admission of testosterone use. Though Cantwell notified USADA of his retirement on May 7, 2026, his period of ineligibility will remain in effect until he returns from retirement and serves the remainder of his sanctions. Additionally, all competitive results from April 30, 2026, onward have been disqualified, including the forfeiture of any medals, points, and prizes earned during that period.
USADA emphasized its commitment to educating athletes and support personnel about anti-doping rules, prohibited substances, and the risks associated with supplements and performance-enhancing drugs. The agency provides resources such as the Global Drug Reference Online (GlobalDRO.com), a drug reference hotline, and educational materials including guides on nutrition, supplements, and clean sport protocols. USADA also conducts outreach sessions with National Governing Bodies and distributes advisories to promote awareness of doping risks.
The agency reiterated its role in preserving the integrity of sport through testing, results management, and research initiatives. USADA encourages reporting of suspected doping violations through multiple channels, including the USADA Play Clean Tip Center, email, phone, or mail. As the official anti-doping agency for the U.S. Olympic and Paralympic Movement, USADA underscored its dedication to protecting clean athletes and ensuring fair competition.
