Contributor(s): Dr John William Devine, Dr Vanessa Heggie, Professor David Papineau | World-class athletes push themselves beyond normal limits and transform their bodies through training and diet. But in the wake of various scandals across the world of sport, we know pharmaceuticals can also play a role. Doping is considered a form of cheating, but should it be? And with the arrival of ‘smart drugs’, this is no longer only a worry for sports. Can we ensure a level playing field, in sports and beyond, or will the advances in drug development always outpace regulation? We explore the philosophy behind all things doping, competing, and cheating. John William Devine is Lecturer in Sports Ethics and Integrity at Swansea University.
