What is a psychoactive substance?

• A. Drug paraphernalia
• B. Psychoactive substance
• C. Inhalant
• D. Controlled substance

Answer: (B)

The idea being tested is what makes a substance psychoactive: it is any chemical that, once inside the body, changes brain activity enough to alter mood, perception, thinking, or behavior. A psychoactive substance is exactly that kind of agent—the one that produces mind-altering effects. This includes a wide range of substances, whether legal or illegal, because the key feature is the effect on mental processes, not how it’s used or its legal status. Drug paraphernalia are items used with drugs, not the drugs themselves; an inhalant refers to a route of administration (inhalation) and can be psychoactive but isn’t the definition of a psychoactive substance; a controlled substance is a legal category, not a description of the substance’s brain effects.
