Neonatal abstinence syndrome: reconstructing the evidence.

Neonatal abstinence syndrome (NAS) is the term used to describe the presence of withdrawal symptoms in neonates exposed prenatally to opiates. Much of what is known about NAS is based on the biomedical model of illness. There is less consideration of the social, historical, and political influences on knowledge development about the NAS phenomenon. Social construction presents an alternate framework within which to consider the diagnosis of NAS and on which to strengthen theoretical foundations, expand research programs, and improve practice.
