Laws and regulations define which professionals can write prescriptions, how they are stored, and how controlled substances are tracked.
State and Federal Oversight
Boards of medicine, pharmacy boards, and agencies such as the DEA set rules. Electronic prescribing for controlled substances is increasingly mandated to improve oversight.
