C. Most other adults drink lightly and
occasionally; a small number of heavy drinkers,
about 7% of adults, consume more than half of
all the alcohol in the United States. Overall,
college students drink more alcohol and are
more likely to binge drink than young adults
who are not in college, but nonstudents are
more likely to be dependent on alcohol.

True. Women usually have a higher
percentage of body fat than men and a
less active form of a stomach enzyme
that breaks down alcohol. Both factors
cause them to become intoxicated
more quickly and to a greater degree.

True. Consuming a number of drinks
over a period of several hours is likely to
cause intoxication, followed by a
hangover; chugging the same amount
in an hour or less can be lethal.

55% adult Americans (age 18 and older) currently drink
14% are former drinkers
31% are lifetime abstainers
Of those who drink:
› 79% are light drinkers
› 14% are moderate drinkers
› 7% are heavy drinkers
› 3.5% are dependent on alcohol
› 4.3% classified as alcohol abusers
Social, economic and medical costs of alcohol abuse are
estimated at over $180 billion per year
Between 20 and 40 percent of all hospital beds are occupied by
people being treated for medical, psychiatric, and traumatic
complications of alcohol use.
Alcohol is responsible for about 85,000 deaths per year
Alcohol is the third leading actual cause of death among
Americans
Alcohol is the leading cause of death among people aged 1524.
Alcohol is the number one drug of abuse.

Within minutes after alcohol is consumed it enters the
bloodstream and nerve cells are numbed.
Nerve messages are slowed to all parts of the body.
Alcohol acts as a relaxant when one or two drinks are
taken.
When larger amounts of alcohol are consumed, the
nerve centers in the brain that govern judgment,
memory, speech, reaction time, coordination,
muscular control, and brain activity are impaired.
The depressive effects of alcohol intensify as the
concentration of alcohol in the blood increases.

20% is rapidly absorbed from the stomach into the
bloodstream
75% is absorbed in the upper small intestines
Remaining is absorbed along the gastro-intestinal
track into the bloodstream
Rate of Absorption
› Carbonation increases rate of absorption
› Artificial sweeteners in drink mixers increase rate of
absorption
› Food in the stomach slows the absorption
› Drink of high concentration slows absorption
› Eventually all the alcohol ingested will be absorbed

Easily moves through most biological membranes
Main site for metabolism is the liver though small
amount is metabolized in the stomach.
2-20% of ingested alcohol is not metabolized but is
excreted unchanged by the lungs, kidneys, and
sweat glands.
› Excreted alcohol causes the breath to smell
› The basis for breath and urine analysis
The body can metabolize about ½ ounce
of alcohol per hour for an average-sized
person.

Blood Alcohol Concentration (BAC) is the
ratio of alcohol in a person’s blood to the
person’s total amount of blood. BAC is
expressed as a percent.
BAC is a measure of intoxication and can
be measured through:
› Urine
› Breath
› Blood samples
©2008 McGraw-Hill Companies. All Rights Reserved.
ChapterTen
13
BAC is determined by:
Amount of time of metabolism
Body weight
Percentage of body fat
higher body fat = higher BAC than more muscular
person of the same weight because fat has fewer blood
vessels
Gender
because of less active stomach enzyme in women,
women are generally smaller and contain more body fat
and hormonal fluctuations during certain times of
menstrual cycle

Age

Less alcohol consumed than can metabolize in
an hour = BAC remains low
› This is how people can consume large amounts over
a long period of time without becoming noticeably
drunk however consider long-term hazards
More alcohol consumed than can metabolize
in an hour = BAC steadily increases
› Person will get more and more drunk
Time is essential to BAC
› Several drinks over several hours results in intoxication
and hangover
› Several drinks in an hour could be lethal

Dependant on the individual.
Alcohol is a Central Nervous System
depressant
At any given BAC, the effects are more pronounced
when the BAC is rapidly increasing than slowly
increasing, steady or decreasing
Low Concentrations .03% -.05%.
› Relaxed, jovial, light-headedness, mild euphoria
Higher Concentrations 0.1% -0.2%.

Dose-response function
› Relationship between the amount of alcohol
or drug consumed and the type and
intensity of the resulting effect
Higher doses are associated with a much
greater probability of auto crashes
Driving with a BAC of 0.14% is more than 40
times more likely to be involved in a crash.
Greater than 0.14% the risk of fatal crash is
estimated to be 380 times higher
Younger drivers result in significant
impairment with BACs as low as 0.02%

each year as a result of alcohol abuse
Alcohol use contributes to over 50% of all murders,
assaults, and rapes. Alcohol is frequently found in the
bloodstream of perpetrators and victims.
The majority of people who attempt suicide have
been drinking, about half of all successful suicides
are alcoholics.
Alcohol use triples the chances of fatal injuries during
leisure activities such as swimming and boating.
More than half of all fatal falls and serious burns
happen to people who have been drinking.

Alcohol poisoning can result from Binge Drinking
Binge Drinking is drinking 5 or more drinks in a
row
› Drinking large amounts of alcohol over a short
period of time can rapidly increase BAC into the
lethal range
Alcohol Poisoning happens as a result of drinking
more alcohol than the body can process.
› Alcohol poisoning can be caused in situations
with inexperienced drinkers, drinking games,
competitions, young drinkers

Binge drinkers can be…
› College students, high school students,

Alcohol alone or in combination with other
drugs is responsible for more toxic Overdose
deaths than any other drug
Death is caused by Central Nervous System
and respiratory depression or by inhaling
fluid or vomit into the lungs
The amount of alcohol it takes to make a
person unconscious is dangerously close to a
fatal dose.

Heavy drinking can result in severe Central
Nervous System depression resulting in

Death from alcohol overdose occurs due to
respiratory failure because of effects on the

Alcohol and Sexual Decision Making
› Frequent binge drinkers are 5 times more likely to engage in
unplanned sexual activity and 5.5 times more likely to have
unprotected sex than non-binge drinkers
› Heavy drinkers are more likely to have multiple sex partners
and to engage in other forms of high-risk sexual behavior
› Rates of STDs and unwanted pregnancies are higher
among people who drink moderately or excessively
› Women who binge drink are at increased risk for rape and
other forms of nonconsensual sex.
› Laws state a person who is very drunk or passed out cannot
consent to sex. If you have sex with a person who is drunk
or unconscious, you are committing sexual assault.

Using Alcohol with other drugs
› Increases effects with both drugs potentially leading to
coma, respiratory depression, and death
Barbiturates, valium-like drugs, narcotics (codeine) and
OTC antihistamines (Benadryl)
› 3 or more drinks per day cause OTC pain relievers like
aspirin, ibuprofen, or acetaminophen to increase risk of
stomach bleeding or liver damage
› Antibiotics and diabetes medications can also interact
dangerously
› When cocaine and alcohol are used together, a toxic
substance called cocaethylene is formed; responsible for
more than half of cocaine-related deaths
