False. Alcohol is a central nervous system depressant, not a stimulant. It slows down the brain and the body's systems. Many people think alcohol is a stimulant because it seems to increase energy levels and reduce inhibitions. However, this is only temporary, and alcohol actually has the opposite effect once it starts to be metabolized by the body. Alcohol consumption can lead to drowsiness, slowed reaction times, and impaired judgment. In large enough quantities, alcohol can cause blackouts, coma, and even death. So while it may seem like alcohol is a stimulant at first, in reality it is a dangerous depressant that should be avoided.
