Doctor
on Call: Smoking
by Jeffrey Rehm, MD
This month
I would like to discuss one of my favorite topics: smoking. I know
this is parenting magazine and the discussion should center around
children and family health. What if I were to say smoking is a childhood
disease with adult manifestations and it affects the whole family?
Then it would pertain to this magazine.
The average
age children begin to smoke is about 12 years old. In some states,
nine years old is the average. It does not take long for a person
to be addicted to nicotine in the cigarettes. Unfortunately, nicotine
is naturally found in our brain as a neurotransmitter. Within our
brain are nicotine receptors which, when stimulated, release dopamine
(another neurotransmitter) into the mesolimbic area of the brain
giving the person a calming or stimulating effect. Once additional
nicotine is introduced from smoking, nicotine receptors within our
brain expand and clamor for more nicotine soon establishing an addiction.
To date, nicotine appears to be the most addictive substance known
(including cocaine). Although nicotine is the addictive substance
in cigarette smoke, nicotine itself causes relatively few health
risks.
Within cigarette
smoke over 60 carcinogens and over 200 toxins are found! This bad
stuff includes ammonia, arsenic, cadmium, carbon monoxide, formaldehyde,
hydrogen cyanide and toluene. The top four causes of death in the
United States are related to cigarette smoking: coronary heart disease,
strokes, cancer, and COPD (emphysema, asthma and chronic bronchitis).
In fact, a lifelong smoking woman will have a shorter life by 14
years (12 years for a man). I think almost everyone agrees that
cigarette smoking is linked to lung cancer (about 90% of the risk
of lung cancer is due to cigarette smoking), but did you know that
smoking is related to oral cavity/pharyngeal, laryngeal, esophageal
pancreatic, kidney, bladder, cervical cancer and leukemia? Smoking
is also related to adverse surgical outcomes, increased risk of
hip fractures, osteoporosis, peptic ulcer disease, decreased fertility
rates and pregnancy complications.
If the above
all pertains to the individual smoker, what about the smoker's family?
Second hand smoke risks are real and include increased risk of sudden
infant death syndrom (SIDS), increased risk of asthma and poorly
controlled asthma, increased risk of childhood middle ear infections,
increased risk of childhood respiratory infections and also lung
cancer.
The best way to prevent all of these dreadful complications of smoking
is never to start. It's very important to talk to children about
not smoking. Most young children find cigarette smoke irritating
and tend to be fairly receptive to the idea smoking is bad for you.
Teenagers may be a different story. Smoking is still seen in the
movies and may be perceived as "cool" so that may be a
reason for trying cigarettes. It may take very few cigarettes to
become addicted for life.... Discussing smoking with teenagers has
been found to be helpful; therefore, I would encourage it.
If someone
is a smoker, it is beneficial to try to stop. Stopping smoking requires
two elements: behavior modification and medication intervention
to improve success. Behavior modification requires changes in habits.
Start small, by for example, not smoking when having morning coffee.
Medication intervention includes nicotine replacement therapies,
Wellbutrin (Zyban) and Varenicline (Chantix). The latter is a new
medication with the best success to date.
Remember, it's
important to realize that it is a and then stop this pediatric disease.
