What category of drugs includes substances like alcohol and sedatives?

The correct answer is depressants, which is a category of drugs that specifically includes substances that slow down brain function and neural activity. Drugs classified as depressants, such as alcohol and sedatives, can induce relaxation, drowsiness, or a decrease in anxiety. These substances are known to reduce the body's basic functions, leading to a calming effect.

Understanding this classification is crucial because depressants can significantly impact driving ability and judgment, increasing the risk of accidents. It’s important to recognize the effects of these drugs on coordination and alertness, as they can impair one's ability to respond appropriately in various situations, especially while operating a vehicle.
