Working While Under the Influence of Performance-Enhancing Drugs: Is One 'More Responsible'?

In his paper "Diminishing and Enhancing Free Will", Walter Glannon (2011) uses the example of a surgeon who takes drugs to enhance her or his capabilities. He concludes that "the surgeon would be responsible for performing more surgeries, but not more responsible for performing them", and argues that an increase in the content of responsibility doe not entail an increase in the degree of responsibility. The question of whether the degree of responsibility can be affected by the use of performance-enhancing substances is fundamental in ethics and law because it impacts directly on the normative practices and legal consequences associated with enhancement (Downie et.al. in press)
