Depressants are drugs that inhibit the function of the central nervous system and are among the most widely used and abused drugs in the world. These drugs operate by affecting neurons in the central nervous system, which leads to symptoms such as drowsiness, relaxation, decreased inhibition, anesthesia, sleep, coma, and even death. The most commonly abused depressants are alcohol, opiates, and benzodiazepines.
