Not all drugs are considered controlled substances. Examples of drugs that are not controlled substances are Donepezil, Xylazine, and Atropine.

Listed chemicals: Chemicals that may be used to manufacture controlled substances. Listed chemicals are regulated in order to prevent the illicit manufacture of controlled substances

Precursor chemicals: Compounds that are required in the synthetic or extraction processes of drug production, and become incorporated into the drug molecule. Not used in the production of cocaine or heroin. The California Department of Justice considers these substances able to produce controlled substances.
