Which activity requires a separate registration from the DEA?

In the context of the DEA regulations, all activities related to controlled substances require a separate registration. Each of the activities listed is regulated to ensure that those who handle controlled substances are properly authorized to do so, maintaining a legal framework for safety and monitoring.

Distributing controlled substances requires a separate registration because it involves transferring these substances from one entity to another, and it's essential that the distributor adheres to specific regulations to prevent diversion and misuse.

Research involving controlled substances also necessitates a separate registration. This is crucial because research on controlled substances can lead to increased potential for abuse or misuse, and it is important to have oversight on who is conducting these studies and under what conditions.

Manufacturing controlled substances requires its own registration as well. This activity not only entails the production of drugs but comes with significant responsibilities regarding compliance, safety, and reporting. Manufacturers must meet stringent requirements to ensure that production does not contribute to illegal distribution.

Thus, all these activities—distributing, researching, and manufacturing controlled substances—mandate separate registrations with the DEA, reinforcing the importance of regulation and oversight in handling controlled substances.
