A<unk>  is a substance that depresses the central nervous system (CNS), resulting in calmness, relaxation, reduction of anxiety, sleepiness, and slowed breathing, as well as slurred speech, staggering gait, poor judgment, and slow, uncertain reflexes.<unk> s may be referred to as tranquilizers, depressants, anxiolytics, soporifics, sleeping pills, or<unk> -hypnotics. This, however, may be inaccurate as<unk> s are a type of depressant as are tranquilizers which are mild in their action compared to that of<unk> s. Also,<unk> s only act as hypnotics (sleep-inducing drugs)in relatively high doses.<unk> s can be abused to produce an overly-calming effect (alcohol being the classic and most common sedating drug). At high doses or when they are abused, many of these drugs can cause unconsciousness (see hypnotic) and even death.
