How many groups of controlled substances are there?

The correct answer is based on the classification of controlled substances as defined by the Drug Enforcement Administration (DEA) in the United States. There are five distinct schedules of controlled substances, each indicating a different potential for abuse, accepted medical use, and the degree of regulation required.

Schedule I substances have the highest potential for abuse and lack accepted medical use, while Schedule V substances have the lowest potential for abuse and are more commonly prescribed for medical purposes. This classification system is crucial for healthcare professionals, including hospital corpsmen, who must understand the regulations and risks associated with various medications to ensure proper handling and administration.

Understanding that there are five schedules helps in recognizing the potential risks and legal implications of prescribing and administering these substances within medical practice. Each schedule is strictly regulated, influencing factors such as prescription requirements, storage, and record-keeping, all of which are essential for maintaining compliance with federal laws.
