Which of the following is NOT a CNS depressant?

CNS depressants slow down brain activity and nervous system functioning, leading to effects like drowsiness, slower reflexes, impaired coordination, and often reduced respiration. Alcohol fits this pattern by dampening neuronal activity across the CNS. Xanax, a benzodiazepine, also depresses CNS activity by enhancing inhibitory GABA signals. Benzedrine, however, is a stimulant; it increases alertness, energy, and CNS activity rather than slowing it down. That’s why it’s the correct choice for “NOT a CNS depressant.” Nebula isn’t recognized as a standard CNS depressant in clinical pharmacology, so the key distinction remains: stimulants elevate CNS activity while depressants diminish it.
