What is a controlled substance?

What is a controlled substance?

• A. Are chemicals or drugs that have been determined to have enough effect on the body and mind of an individual.
• B. Substances regulated for medical use
• C. Substances used only in laboratories
• D. Substances that are harmless

Answer: (B)

Controlled substances are drugs or chemicals that are regulated by law because they have medical use but also a high potential for abuse and harm. The defining idea is regulatory control: they may require prescriptions, secure storage, and detailed record-keeping to prevent diversion and misuse. That’s why the statement that they are substances regulated for medical use is the best fit. Simply saying a substance has effects on the body and mind describes many drugs, not their legal status. Substances used only in laboratories ignore medical use and regulation, and labeling something as harmless contradicts the purpose of control.
