 Finally, proponents of the anti-anti-doping view object morally to the practical implications of anti-doping regulations (especially with regard to policing the use of performance enhancing drugs). On this view, a ban on performance-enhancing drugs should not be imposed, even if justifiable in principle, because the implementation of such a ban would necessarily involve morally objectionable practices. Anti-anti-doping arguments criticise the fight against doping on the grounds that it costs too much (in both economic and moral terms) and secures insufficient benefit in terms of the promotion of compliance and the identification of non-compliance with anti-doping rules (Kayser et al., 2005, 2007). Advocates of this view may endorse principled objections to doping but believe that the institutional requirements for policing such a ban are not morally justifiable. Such an objection includes concerns that the institutional framework associated with anti-doping involves the violation of athletes’ rights (Tamburrini, 2013), that anti-doping policy too closely resembles a criminal justice system (Kornbeck, 2013), and that the normative assumptions that underpin anti-doping campaigns are morally problematic. Anti-anti-doping advocates propose alternative regulations that often involve the legalization of currently banned substances and methods (Pérez Triviño, 2013; Tamburrini, 2000b; Tamburrini and Tännsjö, 2005; Tännsjö, 2009) or the adoption of a harm-reduction approach (Kayser et al., 2005, 2007).
