Before disposal, expired Schedule II controlled substances must be reported to which organization?

The correct answer is reporting expired Schedule II controlled substances to the DEA (Drug Enforcement Administration). The DEA is the federal agency responsible for regulating controlled substances, and this includes overseeing the disposal of such drugs. Expired or unused controlled substances must be managed in a way that prevents misuse, diversion, or environmental harm.

Before disposal, the DEA requires that these substances be reported to ensure that they are handled according to established regulations and that there is accountability in the disposal process. This reporting is vital for maintaining the integrity of controlled substance regulations and protecting public health.

The other organizations listed do not have the same regulatory role concerning the management and disposal of controlled substances. The FDA (Food and Drug Administration) is primarily focused on the safety and efficacy of drugs, while WHO (World Health Organization) deals with international public health issues, and NABP (National Association of Boards of Pharmacy) oversees pharmacy practice but does not have direct authority over controlled substance disposal. Thus, the DEA is the appropriate agency in this scenario.
