Alcohol and College Students
• Approximately 85% of college students consume alcohol
• 1/3 of college students are heavy drinkers
• College drinkers spend more on alcoholic beverages than on soft drinks and textbooks combined

Binge Drinking and College Students
• Binge drinking – 5 drinks in a row for men, 4 drinks in a row for women on a single occasion
• According to the Harvard School of Public Health, 2001:
• 44.8% of students were binge drinkers
• 22.8% were frequent drinkers (binge drink 3 or more times in a 2-week period)
• Frequent binge drinkers are 16 times more likely to miss class, 8 times more likely to get behind in their school work

The Chemical Makeup of Alcohol
• Ethyl alcohol or ethanol – the intoxicating substance
• Fermentation – yeast organisms break down plant sugars, yielding ethanol and carbon dioxide
• Distillation – alcohol vapors from the fermented mash are collected and mixed with water
• Proof – the measure of percentage of alcohol; the alcohol percentage is 50% of the given proof:
• 100 proof vodka is 50% alcohol by volume

Blood Alcohol Concentration (BAC)
• BAC – the ratio of alcohol to total blood volume
• Despite individual differences, alcohol produces some general behavioral effects depending on BAC
• Learned behavioral tolerance – person learns to modify their behavior to appear sober despite a high BAC

Absorption and Metabolism
• Alcohol molecules are sufficiently small and fat-soluble to be absorbed throughout the entire gastrointestinal system
• Factors that influence how quickly body absorbs alcohol:
• Alcohol concentration in beverage
• Amount of alcohol consumed
• Amount of food in stomach
• Pylorspasm
• Mood

Alcohol Poisoning
• Death from alcohol poisoning can be caused by central nervous system and respiratory depression or inhalation of vomit or fluid into the lungs
• The amount of alcohol that causes someone to “pass out” is dangerously close to the “lethal dose”
• Signs of alcohol poisoning:
• Unable to be aroused
• Weak, rapid pulse
• Unusual or irregular breathing pattern
• Cool, damp, pale, bluish skin

Women and Alcohol
• Women have different body fat composition than men
• Women have half the amount of alcohol hydrogenase, the enzyme that breaks down alcohol; if a woman and a man drink the same amount of alcohol, the woman will have a BAC that is 30% higher

Immediate Effects
• The primary action of alcohol is to depress the central nervous system
• Diuretic – results in fluid being drawn out of cerebrospinal fluid and leads to mitochondrial dehydration
• Alcohol irritates the gastrointestinal system
• Hangover
• Congeners – forms of alcohol that are metabolized slower than ethanol and more toxic
• Drug interactions

Long-Term Effects
• Effects on the nervous system
• Cardiovascular effects• Antithrombotic effect
• Liver disease – alcoholic hepatitis and cirrhosis
• Cancer
• Irritant to gastrointestinal system
• Inflammation of the pancreas
• Block absorption of calcium
• Interferes with immunity

Alcohol and Pregnancy
• Fetal alcohol syndrome (FAS) – alcohol consumed during the first trimester may affect organ development, alcohol consumed during the last trimester may affect the central nervous system development
• Fetal alcohol effects (FAE) – children with a history of prenatal alcohol exposure but with fewer than the full physical or behavioral symptoms of FAS

Drinking And Driving
• Approximately 41% of traffic fatalities in 2002 were alcohol related
• According to the College Alcohol Study, 20% of nonbingers, 43% of occasional bingers, and 59% of frequent bingers reported driving while intoxicated

Alcohol Abuse and Alcoholism
• Alcohol abuse – interferes with work, school, or social and family relationships or entails any violation of the law
• Alcoholism – when personal and health problems related to alcohol use are severe and stopping alcohol consumption results in withdrawal symptoms
Copyright © 2006 Pearson Education, Inc., publishing as Benjamin Cummings
The Causes of Alcohol Abuse and Alcoholism
• Biological and family factors:
• Type 1 alcoholics – drinkers that had at least one parent of either sex that was a problem drinker
• Type 2 alcoholics – seen in males only, biological sons of alcoholic fathers
• Social and cultural factors:
• Social pressure
• Family attitude toward drinking
Copyright © 2006 Pearson Education, Inc., publishing as Benjamin Cummings
Effects of Alcoholism on the Family
• Children in alcoholic dysfunctional families generally assume at least one of the following roles:
• Family hero
• Scapegoat
• Lost child
• Mascot

Costs to Society
• Half of all traffic accidents are attributable to alcohol
• In1998, alcohol related costs to society were $184.6 billion when health insurance, criminal justice costs, treatment costs, and lost productivity were factored in
• Responsible for 25% of nation’s medical costs and lost earnings
• 50% of all child abuse cases are the result of alcohol-related problems

Women and Alcoholism
• Trend is for women, especially college-age women to drink more heavily
• Some studies suggest that there are almost as many female as male alcoholics
• Women get addicted faster with less alcohol
• Female alcoholics have death rates 50–100% higher than male alcoholics

Recovery
• The family’s role
• Treatment programs:
• Private treatment facilities
• Family therapy, individual therapy, and group therapy
• Alcoholics Anonymous (AA)
• Al-Anon
• Alateen
Copyright © 2006 Pearson Education, Inc., publishing as Benjamin Cummings
Relapse
• Approximately 60% of alcoholics relapse within the first three months of treatment
• A comprehensive approach is needed – drug therapy, group support, family therapy, and personal counseling designed to improve living and coping skills is usually the most effective course of treatment
