What is one of the main responsibilities of the DEA?

The primary responsibility of the DEA, or Drug Enforcement Administration, revolves around the prevention of diversion and abuse of controlled substances. This encompasses the enforcement of the Controlled Substances Act, which regulates the manufacture, distribution, and dispensing of controlled substances to ensure they are used safely and effectively. The DEA works to combat the illegal drug trade and establishes regulations to limit access to drugs that have a high potential for abuse or addiction. By monitoring and controlling the substances classified within various schedules, the DEA aims to minimize the risk of substance abuse while allowing for legitimate medical use.

The other options relate to aspects outside the main scope of the DEA's responsibilities. While over-the-counter drugs are regulated, they fall under the jurisdiction of the FDA rather than the DEA. Regulating insurance policies for pharmacies does not align with the DEA's mission, as it typically involves state or other federal agencies. Providing pharmaceutical education, while important, is not a core function of the DEA; instead, education might be more within the purview of professional organizations or educational institutions.
