The United States Drug Enforcement Administration (DEA) maintains lists regarding not only the classification of illicit drugs (see DEA Schedules). It also maintains List I of chemicals and List II of chemicals, which contain chemicals which are used to manufacture the controlled substances/illicit drugs. The lists are designated within The Controlled Substances Act, 21 U.S.C. § 802, Definition 34 (list I) and 35 (list II). Although the list is designated by the U.S. Attorney General, the list is considered a DEA list because the DEA publishes and enforces the list.
