What does the US Drug Enforcement Administration (DEA) regulate?

The US Drug Enforcement Administration (DEA) primarily regulates manufacturers and prescribers of controlled substances. This includes enforcing the controlled substances laws and regulations to prevent drug abuse and misuse. The DEA categorizes drugs into schedules based on their potential for abuse, medical use, and safety or dependence liability. Thus, it has the authority to oversee the production, distribution, and prescribing of these substances to ensure they are used safely and legally.

The other options do not fall under the DEA's jurisdiction. Pharmaceutical marketing practices are typically regulated by the FDA and the Federal Trade Commission. Homeopathic remedies, while they may be subject to some federal regulations, do not have the same level of oversight from the DEA as controlled substances do. Similarly, although generic drug formulations are regulated by the FDA to ensure safety and efficacy, they do not involve controlled substance regulations as established by the DEA. Therefore, the specific focus on controlled substances captures the core responsibility of the DEA.
