The anti-doping policies of the World Anti-Doping Agency (WADA) aim to promote a level playing field and protect the health of the athlete. Anti-doping policy discourages research using performance enhancing drugs (PEDs) or methods and prohibits athlete support personnel, including healthcare providers, from providing advice, assistance, or aid to an athlete or others seeking to use, or using PEDs until harm has occurred. Athletes are individually responsible for the presence of a prohibited substance in their bodies and face sanction regardless (...) of knowledge or intent. I will argue (i) that WADA policies fail to meet the epistemic and control conditions needed to adequately assign individual responsibility and (ii) that transferring responsibility for use of PEDs solely to the athlete results in harm. WADA is drifting perilously close to the morally impermissible ‘doing of harm’ to athletes by initiating or sustaining a causal sequence of events that can result in harm. (shrink)
