Tobacco Addiction

What is Tobacco Addiction?
When people are addicted, they have a complusive need to
seek out and use a substance even when they understand the
harm it can cause. Tobacco products-cigarettes, cigars or pipes
and smokeless tobacco-all can lead to addiction. Everyone
knows that smoking is bad for you, and most people that do it
want to quit. Fact is that nearly 35 millon people try to quit each
year, but eventually they relapse.
What happens when someone uses
tobacco for long periods of time?
Long-term use of nicotine frequently leads to
addiction. Research is just beginning to document all
of the changes in the brain that accompany nicotine
addiction. The way that nicontine is absorbed and
metabolized by the body enhances its addictive
potential. Each inhalation brings a rapid distrubution
of nicotine to the brain peaking within 10 seconds and
then the disappearing quickly, along with
the associated pleasureable feelings.
Tobacco Use
Tobacco use leads most commonly to
diseases affecting the heart and lungs,
with smoking being a major risk factor
for heart attacks, strokes, chronic
obstructive pulmonary disease.
What happens when you smoke
tobacco?
When smoking tobacco, the user inhales tar, nicotine,
carbon monoxide, and 200 known poisons into the lungs.
The nicotine in cigarettes is powerfully addictive. All forms
of tobacco, including cigars, pipe tobacco, snuff, and
chewing tobacco, contain the addictive drug nicotine and
can also cause cancer. Like cocaine, heroin, and
marijuana, nicotine increases levels of the neurotransmitter
dopamine, which affects the brain pathways that control
reward and pleasure. For many tobacco users, long-term
brain changes induced by continued nicotine exposure
result in addiction — a condition of compulsive drug
seeking and use, even in the face of negative
consequences.
