Heroin is best categorized as which type of drug?

• A. Stimulant
• B. Inhalant
• C. Depressant
• D. Hallucinogen

Answer: (C)

Drugs are grouped by how they affect the central nervous system. Heroin slows brain activity and body functions, producing sedation, drowsiness, relaxation, analgesia, and often slowed breathing. These depressant effects come from heroin’s action on opioid receptors, which dampen neural activity and respiration. That slowing of essential bodily functions is what defines a depressant. Stimulants would increase alertness and energy, which heroin does not do. Inhalants are a separate category involving inhalation of volatile substances, and hallucinogens alter perception and thought rather than simply slowing the body. So the best fit for heroin is a depressant.
