Intoxication is the temporary state of being impaired, both physically and mentally, from drinking too much alcohol or from using certain drugs. The word intoxication is most commonly used as a synonym for alcoholic drunkenness, but many drugs, both illegal and prescription, can produce a temporary state of mental and physical impairment, including heroin, marijuana, Ecstasy, LSD, opioid painkillers, GHD, ketamine, hashish, and so forth. The degree of intoxication depends upon which drug is used and in what amounts. Even inhaling certain household substances, such as glue or gasoline, can produce short periods of intoxication. There is actually such a thing as water intoxication, which occurs from drinking too much water in too short a time, but it is rare.
