Which drug is a CNS Depressant?

Answer: C — Barbiturates

Barbiturates are a class of drugs that act as central nervous system depressants, meaning that they slow down brain activity. This can result in sedation, relaxation, and a decrease in anxiety. Marijuana (A), Codeine (B), and Nicotine (D) do not have depressant effects on the central nervous system. Marijuana is classified as a hallucinogen, Codeine is a pain reliever, and Nicotine is a stimulant. It is important to know the effects and classifications of different drugs in order to accurately identify which drug is a CNS depressant.
