Athletes should be permitted to use performance-enhancing drugs under strict medical supervision. The current ban is morally incoherent and practically unsustainable. The line between banned substances and legal aids like caffeine, creatine, or LASIK surgery is arbitrary, not principled. If a coffee sharpens a cyclist's reflexes and surgery sharpens a baseball player's vision, why is one allowed and the other punished?

Regulation would eliminate the dangerous black market that has already cost lives through contaminated products and coerced, secretive use. Under transparent rules, doctors would monitor liver, heart, and hormone levels, catching damage early rather than after careers end in scandal.

Most importantly, adults own their bodies. Professional athletes are not children; they sign contracts assuming sophisticated risks every game. Forbidding them from optimizing their own physiology while permitting other bodily modifications treats them as wards of the state. Freedom, safety, and consistency all point in the same direction: legalize, regulate, and let athletes compete.

Performance-enhancing drugs should not be allowed in professional sport because they undermine both fairness and athlete welfare. Sport is meaningful only when competitors succeed within shared rules; permitting drugs would reward access to stronger substances, better medical supervision, and greater financial resources rather than talent, discipline, and training. It would also create coercive pressure: even athletes who preferred to compete naturally would feel compelled to use drugs simply to remain competitive.

The health risks are substantial, including heart disease, hormonal damage, infertility, psychological disorders, and potentially fatal complications. Legalization would not eliminate danger; it could normalize escalating doses and encourage younger athletes to imitate professionals. Moreover, professional sports have a responsibility to model excellence without sacrificing long-term health. Effective testing and transparent medical oversight can be improved, but the basic prohibition should remain. Competition should challenge the limits of human preparation, not turn pharmacological risk into an unwritten requirement for participation.

DeepSeek V4 Flash
Side B65%Side B presents a more coherent and persuasive case by grounding the argument in the fundamental principles of fairness and the coercive pressure that legalization would create, which directly addresses the unique nature of competitive sport. Side A's points about arbitrary lines and bodily autonomy are relevant but less compelling when weighed against the systemic risks to the integrity of competition and athlete welfare.
GLM 5.2
Side B72%Side B's argument about coercive pressure effectively counters Side A's autonomy claim, showing that legalization would make drug use a de facto requirement rather than a free choice. Side B also persuasively distinguishes pharmacological enhancement from legal aids by highlighting escalating health risks and the downstream effects on youth athletes, while Side A's analogy to caffeine and LASIK, though rhetorically appealing, underplays the qualitatively greater dangers of PEDs.
GPT-5.6 Terra
Side B72%Side B more persuasively explains that legalization would create coercive pressure on athletes to use drugs and could amplify health harms rather than merely regulate them away. Its fairness argument also directly addresses unequal access to drugs and medical supervision, while Side A's analogy to caffeine and surgery does not establish that all enhancements carry comparable risks or competitive effects.
Gemini 3.5 Flash-Lite
Side B85%Side B presents a stronger, more coherent case by focusing on the core principles of competitive fairness and the prevention of coercive pressure in sports. While Side A raises valid points about bodily autonomy and the inconsistency of current regulations, Side B successfully argues that legalizing PEDs would transform sport into a contest of pharmacological access rather than natural talent and discipline.
Grok 4.3
Side B72%Side B presents a more coherent and persuasive case by grounding opposition in the core purpose of sport—fair competition based on talent and training rather than resource access—while logically extending health risks to include coercive effects on non-users and younger athletes. Side A's arguments on arbitrariness and bodily autonomy are relevant but weaker, as they overlook how professional leagues inherently impose rules to preserve integrity and do not fully address how regulation would prevent escalation or unequal access. Side B's emphasis on modeling natural excellence aligns better with plausible long-term outcomes for athlete welfare and public trust.
Haiku 4.5
Side B72%Side B more effectively addresses the core tension in Side A's argument: legalization would not eliminate coercion but institutionalize it, as athletes would face mandatory drug use to remain competitive regardless of personal choice. While Side A makes valid points about arbitrary distinctions and bodily autonomy, Side B's emphasis on structural fairness (rewarding talent over pharmaceutical access) and the normalization of escalating health risks presents a more compelling case for why regulation cannot solve the problems legalization creates. Side A underestimates how competitive pressure would override individual consent even in a regulated framework.
LongCat 2.0
Side B85%Side B presents a more comprehensive argument by effectively countering Side A's bodily autonomy claim with the reality of coercive pressure in competitive sports, while also addressing systemic fairness and the broader societal impact on youth that Side A ignores.
