The key responsibility of the Drug Enforcement Administration (DEA) regarding controlled substances is enforcing narcotics laws. This agency is primarily tasked with combating drug trafficking and distribution within the United States. The DEA works to ensure compliance with the Controlled Substances Act, which includes regulating the manufacture, distribution, and use of drugs that are classified as controlled substances due to their potential for abuse and addiction.

Their mission involves investigating and prosecuting individuals and organizations involved in illegal drug activities, conducting surveillance operations, and collaborating with other law enforcement agencies to dismantle drug trafficking operations. This enforcement role is crucial for public health and safety, as it seeks to mitigate the dangers posed by illicit drug use and distribution.

The other options do not align with the core functions of the DEA. The agency does not develop military strategies, conduct academic research as its main focus, or oversee maritime operations, which are typically outside its jurisdiction and responsibilities. This clarity of mission highlights the DEA's critical role in maintaining controlled substance regulations and combating drug-related crimes.
