Any time is the right time to stop smoking.
A host of stop-smoking aids can boost your
odds of success.
In the old days, when smoking was just a bad
habit, willpower was the only way to shuck it.
But sheer willpower didn’t work well then,
and it doesn’t work any better today, even
when almost everyone knows the health hazards
of smoking.
Fortunately, there’s no need to go it
alone. Smokers who want to quit can now choose
from a variety of tools that double or triple
their chances of succeeding. The best approach
uses medication to quell cravings for nicotine
along with some sort of support or counseling
to break the patterns that make a smoker reach
for a cigarette.
Know the enemy
Smokers tend to underestimate the hazards of
smoking, the benefits of quitting, and the barriers
to quitting, says Dr. Nancy A. Rigotti, an associate
professor of medicine at Harvard Medical School
and director of the Tobacco Research and Treatment
Center at Massachusetts General Hospital.
Hazards: Most people
know that smoking increases the chances of developing
lung cancer. But many aren’t fully aware
it’s also a key cause of heart attack,
stroke, and other cardiovascular problems. Smoking
also contributes to many types of cancer besides
lung cancer, as well as emphysema and other breathing
problems, tooth and bone loss, ulcers and acid
reflux, sleeping problems, and a host of other
ills.
Benefits: Quitting
improves the chances of living longer, reduces
the odds of developing the problems listed above,
and slows the spread of tobacco-related diseases.
These benefits hold true even if you stop smoking
after age 65 or if you’ve already developed
a smoking-related illness. For example, smokers
who quit after having a heart attack tend to
live longer than those who keep smoking.
Barriers: Many things
get in the way of stopping smoking. The two biggest
barriers are the physical addiction to nicotine
and the psychological addiction to the habit
of smoking. Others include stress, a mistaken
belief that it’s too late to stop, and
the influence of other smokers.
Tools for quitting
When a panel appointed by the U.S. Public Health
Service reviewed smoking cessation methods, it
made two clear recommendations: Use medicine,
and get counseling and support.
Nicotine is a powerfully addictive substance.
It stimulates the brain’s “reward
center,” creating a sense of pleasure and
alertness. Yet these feelings fade as the body
washes nicotine from the system. They’re
replaced by other sensations that aren’t
so pleasurable (see Withdrawal symptoms),
which nudge a smoker to light up again. Smoking
is basically an effort to keep the brain in its
nicotine comfort zone.
Withdrawal
symptoms
Falling blood levels of nicotine cause
a wide range of symptoms:
- headache
- nausea
- falling heart rate and blood pressure
- fatigue, drowsiness, or insomnia
- irritability
- difficulty concentrating
- anxiety
- increased hunger
- craving for sweets
- craving for tobacco

Easing the craving for nicotine is a key part
of stopping smoking. Several aids can do this
(see Stop-smoking aids). Nicotine patches,
gum, lozenges, nasal spray, and cigarette-shaped
inhalers deliver enough nicotine to satisfy the
body without the tar, carbon monoxide, and other
harmful chemicals found in cigarette smoke. An
antidepressant known as bupropion (Zyban, Wellbutrin)
also alleviates the symptoms of nicotine withdrawal,
even in people who aren’t depressed. Combining
bupropion and nicotine replacement may work the
best of all.

Nicotine replacement is safe, even after a heart
attack. Just as important, patches, gum, and
other nicotine delivery systems are safer than
continued smoking. They don’t increase
the clotting potential of blood or damage the
fragile but important lining of blood vessels,
as smoking does.
By itself, nicotine replacement isn’t
enough. Two thousand years ago, the Roman poet
Ovid wrote, “Nothing is stronger than habit.” Although
he was speaking about love, his words apply perfectly
to smoking. Over time, smokers link having a
cigarette with other activities or feelings.
For some, the smell of coffee or the sound of
a rustling newspaper triggers the urge to smoke.
For others it’s getting into the car, finishing
a meal, or feeling stressed.
Breaking these ingrained links is essential
to successfully stop smoking. Here’s where
counseling and social support come in. These
can help you figure out your smoking cues, devise
plans to break the link between cues and the
act of lighting up, learn to identify and cope
with the symptoms of withdrawal, and anticipate
situations and problems that might make you start
smoking again.
The most effective — and most expensive — way
to do this is by working one-on-one with a smoking
cessation counselor. Group counseling or support
groups run by hospitals, national organizations,
and state or local health departments work almost
as well. Counseling from a telephone quit line
is helpful. And a growing number of people are
finding virtual counseling and support via the
Internet. (See More information.)
A plan
If you want to stop smoking, a game plan will
help you succeed. Here are some steps to consider:
- Pick a “quit day.” Look
at your calendar and decide on a good day to
quit.
- Prepare for it. Choose
a method for controlling nicotine cravings
that you think will best fit you. Talk with
a smoking cessation counselor about strategies
for coping with tobacco triggers.
- Talk to your doctor. Smoking
speeds up how quickly the body processes some
medications. Quitting may mean you’ll
need a lower dose of some drugs.
- The day before. Toss
out cigarettes, lighters, ashtrays, and other
smoking paraphernalia.
- Quit day and beyond. If
you’ve chosen to use some sort of nicotine
replacement, start it up. Keep busy, so you
don’t dwell on the important change you’re
making. When the urge to smoke creeps up on
you, chew some gum, chomp on a carrot stick,
drink a glass of water, or breathe deeply for
a minute or so. Use the habit-breaking tips
you’ve learned.
- Get moving. Starting
an exercise program, or exercising more, can
help you avoid the weight gain that often follows
quitting. It can also burn off quitting-related
restless energy and low moods.
- Seek support. Get
help from a counselor, doctor, friends, or
others who can give you moral and physical
support.
Slip, don’t slide
There’s an important distinction between
a slip (a mistake) and a slide (a relapse). You
slip when you smoke once or twice after your
quit date. You relapse when you go back to your
former smoking pattern. Slipping is common and
doesn’t make you a smoker again. If you
slip, try to figure out what went wrong and how
to fix it the next time. Above all, don’t
let one slip lead to another cigarette, then
another...
The same holds true for a return to smoking.
It’s not a catastrophic failure. You may
have to quit two, three, or even more times before
you stop smoking for good. Not succeeding may
just mean you need more help.
“I see lots of people who tell me they
can’t quit even though they’ve tried
everything,” says Dr. Rigotti. “But
most haven’t tried counseling, which is
enormously helpful, especially when combined
with other approaches.”
