Chemical castration laws, such as one recently adopted in the U.S. State of Louisiana, raise challenging ethical concerns for physicians. Even if such interventions were to prove efficacious, which is far from certain, they would still raise troubling concerns regarding the degree of medical risk that may be imposed upon prisoners in the name of public safety as well as the appropriate role for physicians and other health care professionals in the administration of pharmaceuticals to competent prisoners over the inmates' unequivocal objections. This paper argues that the concerns raised by chemical castration are grave enough that, until they are adequately addressed by policymakers, physicians ought not to participate in the process.
