Perinatal History

The Department of Alcohol and Drug Programs (ADP), Office of Perinatal Substance Abuse (OPSA) was established in 1990 by Assembly Bill 3010 to develop a coordinated state strategy to address the substance abuse treatment needs of pregnant and parenting women.

In the early 1990s, OPSA released the Perinatal Substance Exposure Study, leading to the development of the Perinatal Services Network (PSN). The perinatal guidelines were first released in 1993. All perinatal treatment programs receiving public funds must adhere to the guidelines.
