Alcoholism,
also known as “alcohol dependence,” is a disease that includes four symptoms:
- Craving: A strong need,
or compulsion, to drink.
- Loss of control: The
inability to limit one’s drinking on
any given occasion.
- Physical dependence:
Withdrawal symptoms, such as nausea, sweating,
shakiness, and anxiety, occur when alcohol
use is stopped after a period of heavy drinking.
- Tolerance: The need
to drink greater amounts of alcohol in order
to “get high.”
People who are not alcoholic sometimes do
not understand why an alcoholic can’t
just “use a little willpower”
to stop drinking. However, alcoholism has
little to do with willpower. Alcoholics are
in the grip of a powerful “craving,”
or uncontrollable need, for alcohol that overrides
their ability to stop drinking. This need
can be as strong as the need for food or water.
Although
some people are able to recover from alcoholism
without help, the majority of alcoholics need
assistance. With treatment and support, many individuals
are able to stop drinking and rebuild their lives.
Many
people wonder why some individuals can use alcohol
without problems but others cannot. One important
reason has to do with genetics. Scientists have
found that having an alcoholic family member makes
it more likely that if you choose to drink you
too may develop alcoholism. Genes, however, are
not the whole story. In fact, scientists now believe
that certain factors in a person’s environment
influence whether a person with a genetic risk
for alcoholism ever develops the disease. A person’s
risk for developing alcoholism can increase based
on the person’s environment, including where
and how he or she lives; family, friends, and
culture; peer pressure; and even how easy it is
to get alcohol.
How can
you tell whether you may have a drinking problem?
Answering the following four questions can help
you find out:
- Have you ever felt you
should cut down on your drinking?
- Have people annoyed you
by criticizing your drinking?
- Have you ever felt bad
or guilty about your drinking?
- Have you ever had a drink
first thing in the morning (as an “eye
opener”) to steady your nerves or get
rid of a hangover?
One “yes”
answer suggests a possible alcohol problem. If
you answered “yes” to more than one
question, it is highly likely that a problem exists.
In either case, it is important that you see your
doctor or other health care provider right away
to discuss your answers to these questions. He
or she can help you determine whether you have
a drinking problem and, if so, recommend the best
course of action.
Even if you answered
“no” to all of the above questions,
if you encounter drinking-related problems with
your job, relationships, health, or the law, you
should seek professional help. The effects of
alcohol abuse can be extremely serious—even
fatal—both to you and to others.

Crack and Cocaine
Cocaine is a powerfully addictive stimulant drug.
The powdered, hydrochloride salt form of cocaine
can be snorted or dissolved in water and injected.
Crack is cocaine that has not been neutralized
by an acid to make the hydrochloride salt. This
form of cocaine comes in a rock crystal that can
be heated and its vapors smoked. The term “crack”
refers to the crackling sound heard when it is
heated.*
Regardless
of how cocaine is used or how frequently, a user
can experience acute cardiovascular or cerebrovascular
emergencies, such as a heart attack or stroke,
which could result in sudden death. Cocaine-related
deaths are often a result of cardiac arrest or
seizure followed by respiratory arrest.
Health
Hazards
Cocaine is a strong central nervous system stimulant
that interferes with the reabsorption process
of dopamine, a chemical messenger associated with
pleasure and movement. The buildup of dopamine
causes continuous stimulation of “receiving”
neurons, which is associated with the euphoria
commonly reported by cocaine abusers.
Physical
effects of cocaine use include constricted blood
vessels, dilated pupils, and increased temperature,
heart rate, and blood pressure. The duration of
cocaine’s immediate euphoric effects, which
include hyper stimulation, reduced fatigue, and
mental clarity, depends on the route of administration.
The faster the absorption, the more intense the
high. On the other hand, the faster the absorption,
the shorter the duration of action. The high from
snorting may last 15 to 30 minutes, while that
from smoking may last 5 to 10 minutes. Increased
use can reduce the period of time a user feels
high and increases the risk of addiction.
Some users
of cocaine report feelings of restlessness, irritability,
and anxiety. A tolerance to the “high”
may develop—many addicts report that they
seek but fail to achieve as much pleasure as they
did from their first exposure. Some users will
increase their doses to intensify and prolong
the euphoric effects. While tolerance to the high
can occur, users can also become more sensitive
to cocaine’s anesthetic and convulsant effects
without increasing the dose taken. This increased
sensitivity may explain some deaths occurring
after apparently low doses of cocaine.
Use of cocaine
in a binge, during which the drug is taken repeatedly
and at increasingly high doses, may lead to a
state of increasing irritability, restlessness,
and paranoia. This can result in a period of full-blown
paranoid psychosis, in which the user loses touch
with reality and experiences auditory hallucinations.
Other complications
associated with cocaine use include disturbances
in hearth rhythm and heart attacks, chest pain
and respiratory failure, strokes, seizures and
headaches, and gastrointestinal complications
such as abdominal pain and nausea. Because cocaine
has a tendency to decrease appetite, many chronic
users can become malnourished.
Different
means of taking cocaine can produce different
adverse effects. Regularly snorting cocaine, for
example, can lead to loss of sense of smell, nosebleeds,
problems with swallowing, hoarseness, and a chronically
runny nose. Ingesting cocaine can cause severe
bowel gangrene due to reduced blood flow. People
who inject cocaine can experience severe allergic
reactions and, as with any injecting drug user,
are at increased risk for contracting HIV and
other bloodborne diseases.
Added
Danger: Cocaethylene
When people mix cocaine and alcohol consumption,
they are compounding the danger each drug poses
and unknowingly forming a complex chemical experiment
within their bodies. Research has found that the
human liver combines cocaine and alcohol and manufactures
a third substance, cocaethylene, that intensifies
cocaine’s euphoric effects, while potentially
increasing the risk of sudden death.
