Which substance is NOT classified as a CNS depressant?

• A. Alcohol
• B. Xanax
• C. Nembutal
• D. Benzedrine

Answer: (D)

Benzedrine is classified as a central nervous system (CNS) stimulant rather than a depressant. It was historically used to treat conditions such as attention disorders and narcolepsy due to its stimulating effects, which increase alertness and energy levels. This contrasts sharply with substances like alcohol, Xanax (a benzodiazepine), and Nembutal (a barbiturate), all of which are known for their CNS depressant properties, leading to effects such as reduced anxiety, sedation, and impaired motor coordination. Understanding the classification of substances by their effects on the CNS is crucial for recognizing how they can impact an individual’s behavior and health, especially in the context of substance use and treatment in clinical settings.
