Drug Enforcement Administration (DEA)
The US federal agency responsible for enforcing controlled substance laws, classifying drugs into schedules, and investigating illegal manufacture and distribution. The DEA works alongside the FDA — the FDA evaluates medical utility while the DEA assesses abuse potential and assigns schedules.
Technical Context
The DEA's 8-factor analysis for scheduling decisions evaluates: (1) actual or relative potential for abuse, (2) scientific evidence of pharmacological effect, (3) current state of scientific knowledge, (4) history and current pattern of abuse, (5) scope, duration, and significance of abuse, (6) risk to public health, (7) psychic or physiological dependence liability, (8) whether the substance is an immediate precursor of a controlled substance. The FDA provides the HHS Secretary's scientific and medical evaluation (including abuse potential assessment) to the DEA, which makes the final scheduling decision. DEA registration is required for: manufacturers, distributors, researchers, practitioners prescribing, and pharmacies dispensing controlled substances. Registration involves background checks, facility inspections, and ongoing compliance monitoring.
