In the early 1970’s, as part of its efforts to increase treatment for substance use disorder and reduce the stigma surrounding such treatment, the federal government enacted the Drug Abuse Office and Treatment Act of 1972. That Act included a statutory provision for the confidentiality of patient records, now codified at 42 U.S.C. § 290dd-2. This section provides the legal basis for regulations first adopted in 1975 that supplement and expand on the confidentiality provisions of 42 U.S.C. § 290dd-2. These regulations, known colloquially as “42 C.F.R. Part 2” or just “Part 2”, provide increased protection for the records of patients receiving treatment for substance use disorder. Subsequent amendments over the years to both 42 U.S.C. § 290dd-2 and 42 C.F.R. Part 2 served to modernize, clarify, and expand upon the protections granted by the original provisions.
