Alcohol

For people age 21 and older, alcohol is a legal drug. Alcohol is a depressant, a drug that decreases the activity of the central nervous system. Alcohol increases circulation to the skin, decreases blood flow to internal organs, and lowers body temperature. Alcohol causes the kidneys to excrete more water, which can cause dehydration. As drinking continues, judgment and coordination become impaired, speech slurs, and reaction time lengthens. Respiration rate slows after an initial increase. High doses of alcohol can cause death by respiratory failure. The severity of these effects depends largely on blood alcohol concentration (BAC), a measurement of the amount of alcohol in the blood. A BAC of 0.30 or greater can cause unconsciousness, and a BAC of 0.50 can be fatal.

Alcohol is a factor in nearly 50 percent of fatal car crashes involving young people. Alcohol can contribute to harmful drug interactions. For example, when alcohol is combined with another depressant, the cumulative effects can slow the respiratory systems to the point of death. Alcohol consumed during pregnancy can lead to fetal alcohol syndrome, as shown in Figure 49-16.
