Alcohol is the most
commonly used recreational drug. Taken in moderation, it
can be compatible with a healthy lifestyle. But alcohol
abuse causes problems that reach far beyond drinkers
themselves. Alcoholism has defined as "the nations'
number one health problem" a major cause of
disrupted family life, automobile and industrial
accidents, poor job performance, and increasing crime
rates.Cirrhosis of the liver, almost invariably a result of alcohol abuse, is the seventh leading cause of death. In addition, alcohol has been implicated as a contributor to 50 percent of fatal automobile accidents, 53 percent of fire deaths, 45 percent of drownings, 22 percent of home accidents, and 36 percent of pedestrian accidents. Violent crimes attributed to alcohol abuse include 64 percent of murders, 41 percent of assaults, 34 percent of rapes, 30 percent of suicides, and 60 percent of child abuse. The financial toll of alcohol abuse is heavy, too. The pregnant woman who drinks heavily risks giving birth to a child with fetal alcohol syndrome (FAS) a pattern of physical and mental defects that may include malformed facial characteristics, growth deficiency, heart defects, poor neurological coordination, and mental retardation. FAS has become a problem of large proportion, since there are millions of alcoholic women of childbearing age. Studies looked at data pregnancies and found that consumption of at least one to two drinks daily was associated with a substantially increased risk of producing a growth-retarded infant. Even though an occasional drink may not cause a problem, alcohol has no positive effects on pregnancy to recommend it, and thus pregnant women, or those who wish to get pregnant, are advised not to drink at all. Finally, heavy drinkers, especially those who also smoke cigarettes, are at an unusually high risk for oral cancer and cancers of the larynx and esophagus. Is it safe to drink at all? For some people, light to moderate drinking does not seem to have any serious effect. The problem is knowing how much is harmless for whom. Some people, for example, can develop cirrhosis of the liver with only one drink per day, while ten drinks per day will not lead to cirrhosis in others (although this amount may have other serious consequences). At what point does social drinking become alcoholism? For those who still want to enjoy an occasional drink, there is much that can be done to promote a healthy, positive attitude toward alcohol. The following suggestions for keeping alcohol use moderate are especially important for parents of teenagers and young adults. |

| Since alcohol so easily permeates every cell and
organ of the body, the physical effects of chronic
alcohol abuse are wide-ranging and complex. Large doses
of alcohol invade the body's fluids and interfere with
metabolism in every cell. Alcohol damages the liver, the
central nervous system, the gastrointestinal tract, and
the heart. Alcoholics who do not quit drinking decrease
life expectancy by 10 to 15 years. Alcohol also can impair vision, impair sexual function, slow circulation, cause malnutrition, cause water retention (resulting in weight gain and bloating), lead to pancreatitis and skin disorders (such as middle-age acne), dilate blood vessels near the skin causing "brandy nose," weaken the bones and muscles, and decrease immunity. The liver breaks down alcohol in the body and is therefore the chief site of alcohol damage. Liver damage may occur in three irreversible stages. Fatty Liver. Liver cells are infiltrated with abnormal fatty tissue, enlarging the liver. Alcoholic Hepatitis. Liver cells swell, become inflamed, and die, causing blockage. (Causes between 10 and 30 percent mortality rate.) Cirrhosis. Fibrous scar tissue forms in place of healthy cells, obstructing the flow of blood through the liver. Various functions of the liver deteriorate with often fatal results. (Found in 10 percent of alcoholics.) A diseased liver: Cannot convert stored glycogen into glucose, thus lowering blood sugar and producing hypoglycemia. Inefficiently detoxifies the bloodstream and inadequately eliminates drugs, alcohol, and dead red blood cells. Cannot manufacture bile (for fat digestion), prothrombin (for blood clotting and bruise prevention), and albumin (for maintaining healthy cells). Alcohol in the liver also alters the production of digestive enzymes, preventing the absorption of fats and proteins and decreasing the absorption of the vitamins A, D, E, and K. The decreased production of enzymes also causes diarrhea. |

| Alcohol profoundly disturbs the structure and
function of the central nervous system, disrupting the
ability to retrieve and consolidate information. Even
moderate alcohol consumption affects cognitive abilities,
while larger amounts interfere with the oxygen supply to
the brain, a possible cause of blackout or temporary
amnesia during drunkenness. Alcohol abuse destroys brain
cells, producing brain deterioration and atrophy, and
whether the organic brain damage and neuropsychological
impairment linked to alcohol can be reversed is unknown.
Alcohol also alters the brain's production of RNA (a
genetic "messenger"), and serotonin,
endorphins, and natural opiates whose function may be
linked to the addictive process. A neurological disorder called Wernicke-Korsakoff's syndrome results from vitamin B deficiencies produced by alcoholism and the direct action of alcohol on the brain. Symptoms of this condition include amnesia, loss of short-term memory, disorientation, hallucinations, emotional disturbances, double vision, and loss of muscle control. Other effects include mental disorders such as increased aggression, antisocial behaviour, depression, and anxiety. |

| Large amounts of alcohol may inflame the mouth, esophagus, and stomach, possibly causing cancer in these locations, especially in drinkers who smoke. Alcohol increases the stomach's digestive enzymes, which can irritate the stomach wall, producing heartburn, nausea, gastritis, and ulcers. The stomach of a chronic drinker loses the ability to adequately move food and expel it into the duodenum, leaving some food always in the stomach, causing sluggish digestion and vomiting. Alcohol may also inflame the small and large intestines. | |||
| Moderate daily drinking may be good for the heart, but for many the risks outweigh the benefits. Even one binge may produce irregular heartbeats, and alcohol abusers experience increased risk of high blood pressure, heart attacks, heart arrhythmia, and heart disease. Alcohol may cause cardiomyopathy (a disease of the heart muscle). Cessation of drinking aids recovery from this condition. | |||
| Three to 6 days after a heavy drinker (drinking a fifth of liquor a day) completely stops drinking, alcohol is finally gone from the body, and acute and life-threatening effects may occur. Withdrawal phenomena include sleep disorders such as insomnia, visual and auditory hallucinations, disorientation, alcoholic convulsions, epileptic seizures of the grand mal type, and delirium tremens accompanied by acute anxiety and fear, agitation, fast pulse, fever, and extreme perspiration. Consequently, alcoholics who decide to quit drinking should do so under competent medical supervision. | |||
