It is the nicotine in the tobacco that is addictive. This chemical is
absorbed by the brain where it changes the brain chemistry and affects
your mood. The interior of your lungs contains a very large surface
area designed to absorb oxygen into the blood stream. This same area
also absorbs nicotine very well giving the smoker a sudden rush of
nicotine. The nicotine is carried directly to the brain with each puff.
The
mid-brain is the area of your brain that controls your moods and
emotions; it is this area of the brain that nicotine targets. The
presence of nicotine causes a relaxing pleasant feeling, however the
absence of nicotine causes mood swings including irritability, anxiety
and cravings. A nicotine replacement system such as nicotine gum can
help alleviate these feelings.
Every time a smoker smokes the rush
of nicotine immediately affects the brain, this helps to reinforce the
smoking habit. When a person is trying to quit smoking they have to deal
with the physical nicotine addiction as well as the psychological
addiction to the act of smoking. For most people it is the habit of
smoking that is harder to break than the physical addiction to nicotine.
Most
smokers have many psychological triggers linked to smoking. Some of
the more common ones are driving, talking on the phone and right after a
meal. These are so strong that people have been known to reach for a
cigarette during these times up to several years after they have quit.
Stressful situations will frequently trigger strong cravings as well.
Despite
the fact that nicotine is always addictive the level of physical
addiction can vary dramatically from one person to the next. There seems
to be a genetic link to this. Some people metabolize nicotine far
faster than others; these people will have a much stronger physical
addiction than someone whose body metabolizes it slower. There is an
enzyme created in the liver that breaks down the nicotine. People with
lower amounts of this enzyme are less likely to smoke and if they do
smoke they are more likely to be light smokers.
It is possible
that there is even a genetic link to the psychological addiction. There
is evidence that how you handle stress is at least partially controlled
by genetics. Since smoking is often used to help people handle stress
your genes could influence this side of the smoking habit.
Despite
all of this it is possible to quit smoking, more and more people are
kicking the habit every day. For some people it is fairly easy to quit
where as others will find it very difficult and will probably try and
fail several times before they are able to quit for good. There are
medical treatments as well as counseling and therapy to help with all
aspects of quitting.
Just like any other habit the longer you have
been doing it the harder it is to quit. Young smokers may find it
easier to quit since the habit is not as ingrained as in some one that
has been smoking for twenty or more years. People who have been smoking
longer though are frequently more aware of the cost of smoking and can
be far more motivated to quit.
