and how alcohol affects the brain and nervous system. As you study the powerpoint, look for answers to

• One problem with drinking even moderate amounts is that the effect is deceptive. A person may feel he is better coordinated and more alert after a few drinks, when actually he is less coordinated and his judgment is impaired.

• A wise drinker will never take a drink when he thinks he needs one. He does not want to become dependent on the effects of alcohol. Perhaps he has known persons who have become alcoholics…….

• Some drinkers are wiser than others. They have taken the trouble to learn how much they can safely drink.

• A wise drinker eats while he drinks. He knows the food in his stomach slows down the passage of alcohol into the blood stream.

• Alcoholism is a medical and social problem. The alcoholic must want to be helped. He must seek help from medical and social service agencies.

• He must learn never again to touch alcoholic beverages. For him, one drink invariably leads to a bout of excessive drinking.

• Throughout the world alcoholism causes millions of broken homes.

• Industry suffers a loss of many millions of dollars a year in absenteeism and lowered efficiency because of excessive use of alcoholic beverages

• Today, many different kinds of alcoholic beverages are available. Americans spend over a hundred million dollars on them.

• Fortunately, most drinkers do not misuse alcohol. They are aware that it is a drug, and that like all drugs it must be used carefully, and moderately, to avoid disastrous consequences.
