Established in 1973, the DEA aims to combat drug trafficking and abuse through investigations, intelligence sharing, and collaboration with other law enforcement agencies. The DEA also regulates the legal production and distribution of controlled substances, ensuring that medications are used safely and effectively. It plays a crucial role in addressing issues related to illegal drugs, including opioids, cocaine, and methamphetamine, while promoting public health and safety.
