The Confidentiality of Substance Use Disorder Patient Records (42 CFR Part 2, commonly known as “Part 2”) is a federal regulation enacted to encourage substance abusers to seek treatment without the fear of stigmatization or criminal prosecution. The regulations were updated and modernized in 2017 to reflect a need to better align Part 2 with the U.S. health care delivery system while retaining important privacy protections.
