Alcohol is a depressant and acts as a sedative to the brain. Although many people feel stimulation when drinking, this is indirect. Even a small amount of alcohol causes depression of those parts of the brain that control judgment, self-control and inhibition. The release from inhibition causes the feeling of stimulation. As greater amounts of alcohol enter the system, the parts of the brain controlling coordination and physical reflexes become depressed.
Regardless of the source, when alcohol enters the blood system the effects are the same. One standard-size drink, whether it is a 12-ounce beer, a 5-ounce glass of wine, or a cocktail, equals 1 ounce of pure alcohol. Many people think a beer contains less alcohol than a standard mixed drink. This is because it usually takes longer to drink beer than it does a cocktail. And beer is much more filling. Also, cocktails sometimes are mixed stronger than a standard drink, making them equal to two normal servings of beer or wine.
