Which of the following is NOT a type of CNS Depressant mentioned?

Amphetamines are classified as central nervous system (CNS) stimulants, not depressants. CNS depressants are substances that slow down brain activity and can lead to effects such as sedation, relaxation, and decreased inhibition.

Barbiturates, alcohol, and benzodiazepines all fall under the category of CNS depressants. Barbiturates can be prescribed for anxiety or sleep disorders, alcohol is widely known for its depressant effects, and benzodiazepines are commonly used for anxiety relief and sedation. Since amphetamines serve to increase alertness and energy levels, they do not fit the definition of CNS depressants, making this choice the correct answer.
