The capacity to treat pain has never been greater; but, as you will read in the articles that follow, the problem of undertreated and neglected pain in the United States persists. Deep-seated perceptions and practices undergird this strong and well-documented pattern of neglect. Among the reasons frequently noted for the inadequacy of treatment for pain, however, is that the legal system actually penalizes effective interventions to relieve pain while it leaves neglect of pain unthreatened. It is the mission of the American Society of Law, Medicine & Ethics (ASLME) to explore areas, such as this one, where developments in medicine directly encounter the law and, in turn, create ethical issues for clinicians, regulators, patients, and lawyers.

This special issue of the Journal of Law, Medicine & Ethics is part of a multi-year project in which ASLME, with the wonderful support of the Mayday Fund, has worked to address legal and regulatory barriers to effective pain relief.
