Binge drinking represents a conscious effort to consume multiple alcoholic beverages within a short period of time with the goal of intoxication. Sometimes, the goal is a euphoric state. Some drinkers imbibe to unconsciousness.
For statistical purposes, a “drink” represents a 12-ounce beer (5 percent alcohol), an 8-ounce malt liquor (7 percent alcohol), a 5-ounce serving of wine (12 percent alcohol) or a 1.5-ounce serving of whiskey (80 proof or 40 percent alcohol).
Blood alcohol level (BAC) is expressed in milligrams of alcohol per 100 milliliters of blood. A BAC of 0.2 means that 0.2 percent of blood volume is alcohol. In the U.S., a BAC of 0.08 or above defines intoxication. Certain effects of alcohol appear at a lower BAC: relaxation, sleepiness, mild impairment of coordination. As BAC increases, a drinker may become aggressive, leading to a risk of injury to self or others. Judgment may deteriorate. Memory and coordination will be impaired. Driving skills will deteriorate.
Dr. Clif CleavelandA blood alcohol level of 0.08 or above defines “driving under the influence” for ages 21 and older. Any blood alcohol level for drivers under age 21 qualifies as DUI.
When the BAC exceeds 0.3, a drinker may lose consciousness. If he should vomit while unconscious, he may aspirate and die. Vital functions of circulation and respiration decline. Blood sugar may fall to a dangerous level. Fifty percent of adults will die if BAC reaches 0.4 or above. Because alcohol in the digestive tract will continue to be absorbed after consciousness is lost, a lethal BAC may be reached an hour or longer following the last drink.
