People have many questions about tobacco that can sometimes be hard to
answer. They include questions about tobacco, including cigarettes,
cigars, spit and other types of smokeless tobacco, and other tobacco
products; nicotine; addiction; and quitting. Many of those questions
are answered here. Here we also talk about how smoking and tobacco can
affect a person's health, including the heart, circulation, and lungs,
its effect on unborn babies, and how it affects the development of
cancer and other diseases.
Is there a safe way to smoke
cigarettes?
No. All cigarettes can damage the human body. Any smoking is
dangerous. Cigarettes are the only legal product whose advertised and
intended use -- smoking -- is harmful to the body and causes cancer.
Although some people try to make their smoking habit safer by
smoking fewer cigarettes, most smokers find that hard to do. Research
has found that even smoking as few as 1 to 4 cigarettes a day can lead
to serious health outcomes, including an increased risk of heart
disease and a higher risk of dying at a younger age.
Some people think that switching from high-tar and
high-nicotine cigarettes to those with low tar and nicotine makes
smoking safer, but this is not true. When people switch to brands with
lower tar and nicotine, they often end up smoking more cigarettes, or
more of each cigarette, to get the same nicotine dose as before.
Smokers have been led to believe that "light" cigarettes have
a lower health risk and are a good option to quitting. This is not
true. A low-tar cigarette can be just as harmful as a high-tar
cigarette because a person often takes deeper puffs, puffs more often,
or smokes them to a shorter butt length. Studies have not found that
the risk of lung cancer is any lower in smokers of "light" or low-tar
cigarettes.
Hand-rolled cigarettes, while reported to be a cheaper and
healthier way to smoke, are not safer than commercial brands. In fact,
lifelong smokers of hand-rolled cigarettes have been found to have an
increased risk of cancers of the larynx (voice box), esophagus (tube
that connects the mouth to the stomach), mouth, and pharynx (throat)
when compared with smokers of manufactured cigarettes.
"All natural" cigarettes are marketed as having no chemicals
or additives and rolled with 100% cotton filters. There is no proof
they are healthier or safer than other cigarettes, nor is there good
reason to think they would be. Smoke from these cigarettes, like the
smoke from all cigarettes, contains many carcinogens (agents that cause
cancer) and toxins that come from the tobacco itself, including tar and
carbon monoxide.
Herbal cigarettes, even though they do not contain tobacco,
also give off tar and carbon monoxide and are dangerous to your health.
The bottom line is there's no such thing as a safe smoke.
Is cigarette smoking really
addictive?
Yes. The nicotine in cigarette smoke causes an addiction to
smoking. Nicotine is an addictive drug (just like heroin and cocaine)
for 3 main reasons.
- When taken in small amounts, nicotine creates pleasant
feelings that make the smoker want to smoke more.
- Smokers usually become dependent on nicotine and suffer
physical and emotional (psychological) withdrawal symptoms when they
stop smoking. These symptoms include nervousness, headaches, and
trouble sleeping.
- Because nicotine affects the chemistry of the brain and
central nervous system, it can affect the mood and nature of the
smoker.
What does nicotine do?
In large doses nicotine is a poison and can kill by stopping a
person's breathing muscles. Smokers usually take in small amounts that
the body can quickly break down and get rid of. The first dose of
nicotine makes a person to feel awake and alert, while later doses
produce a calm, relaxed feeling.
Nicotine can make new smokers, and regular smokers who get too
much of it, feel dizzy or sick to their stomachs. The resting heart
rate for young smokers increases 2 to 3 beats per minute. Nicotine also
lowers skin temperature and reduces blood flow in the legs and feet. It
may play a role in increasing smokers' risk of heart disease and
stroke.
Many people mistakenly think that nicotine is the substance in
tobacco that causes cancer. This belief may cause some people to avoid
using nicotine replacement therapy when trying to quit. Although
nicotine is what gets (and keeps) people addicted to tobacco, other
substances in tobacco are responsible for its cancer-causing effects.
There is some early evidence from lab-based studies that nicotine may
help existing tumors to grow, but whether these results apply to people
is not yet known and more research is needed.
Why do people begin to smoke?
Most people begin smoking as teens, usually because of
curiosity and peer pressure. People with friends and/or parents who
smoke are more likely to take up smoking than those who don't.
The tobacco industry's ads and other promotions for its
products are another big influence in our society. The tobacco industry
spends billions of dollars each year to create and market ads that show
smoking as an exciting, glamorous, and healthy adult activity.
Who is most likely to become
addicted?
Anyone who starts smoking is at risk of becoming addicted to
nicotine. Studies show that cigarette smoking is most likely to become
a habit during the teen years. The younger a person is when he or she
begins to smoke, the more likely he or she is to develop nicotine
addiction. Almost 90% of adult smokers started at or before age 19.
How many people smoke cigarettes?
Among adults in the United States, cigarette smoking has
declined from about 42% of the population in 1965 to about 20.9% in
2005 (the latest year for which numbers are available). About 45
million adults currently smoke cigarettes. About 23.9% of men and 18.1%
of women were smokers. Education seems to affect smoking rates, as
shown by a steady decrease in the smoking rates in groups with a higher
level of education.
Is smoking common among young
people?
Yes. Tobacco use, including smoking cigarettes, using chew or
spit tobacco, and dipping snuff, is common among American youth,
according to the most recent government surveys.
Despite declines in recent years, about 1 in 3 male high
school students (32%) and 1 in 4 female high school students (25%) used
some type of tobacco in 2005. More than 1 in 5 students (23%) were
considered current cigarette smokers. Over half of these students
(about 55%) reported they had tried to quit smoking during the past
year. Cigar smoking was also common among high school students (about
14%).
Also, about 12% of middle school students used some form of
tobacco, with cigarettes (8%) being the most common.
Tobacco use is higher among male students for all products
except cigarettes, where the numbers for boys and girls are now about
the same.
Other problems have been linked to smoking. Studies have shown
that students who smoke are more likely to use other drugs, get in
fights, carry weapons, attempt suicide, and engage in high-risk sexual
behaviors.
What in cigarette smoke is
harmful?
Cigarette smoke is a complex mixture of chemicals produced by
the burning of tobacco and the additives. The smoke contains tar, which
is made up of more than 4,000 chemicals, including over 60 known to
cause cancer. Some of these substances cause heart and lung diseases,
and all of them can be deadly. You might be surprised to know some of
the chemicals found in cigarette smoke. They include:
- cyanide
- benzene
- formaldehyde
- methanol (wood alcohol)
- acetylene (the fuel used in welding torches)
- ammonia
Cigarette smoke also contains the poisonous gases nitrogen
oxide and carbon monoxide. The active ingredient that produces the
effect people are looking for is nicotine, an addictive drug.
Does smoking cause cancer?
Yes. Tobacco use accounts for about one- third of all cancer
deaths in the United States. Smoking causes about 87% of lung cancer
deaths. Smoking also causes cancers of the larynx (voice box), mouth,
pharynx (throat), esophagus (swallowing tube), and bladder, and
contributes to the development of cancers of the pancreas, cervix,
kidney, and stomach. It is also linked to the development of some types
of leukemia. Cigars, pipes, and spit and other types of smokeless
tobacco all cause cancers, too. There is no safe way to use tobacco.
How does cigarette smoke affect
the lungs?
Damage to the lungs begins early in smokers, and all cigarette
smokers have a lower level of lung function than non-smokers. This
continues to worsen as long as the person smokes. Cigarette smoking
causes many lung diseases that can be just as dangerous as lung cancer.
Chronic Bronchitis
Chronic bronchitis is a disease where the airways produce too
much mucus, forcing the smoker to cough it out. It is a common problem
for smokers. The lungs start to produce large amounts of mucus more and
more of the time. The airways become inflamed (swollen) and the cough
becomes chronic -- it doesn't get better or go away. Airways get
blocked by scars and mucus. Serious infections can also result.
Emphysema
Cigarette smoking is also the major cause of emphysema -- a
disease that slowly destroys a person's ability to breathe. Oxygen
reaches the blood by moving across a large surface area in the lungs.
Normally, thousands of tiny sacs make up this surface area. With
emphysema, the walls between the sacs break down and create larger but
fewer sacs. This decreases the lung surface area, which lowers the
amount of oxygen reaching the blood. Over time, the lung surface area
can become so small that a person with emphysema often must gasp for
breath.
Shortness of breath (especially when lying down), a chronic
mild cough (which is often dismissed as "smoker's cough"), feeling
tired, and sometimes weight loss are early signs of emphysema. People
with emphysema are at risk for many other problems linked to weak lung
function, including pneumonia. In later stages of the disease, patients
can only breathe comfortably with the help of an oxygen tube under the
nose. Emphysema cannot be reversed, but it can be slowed down --
especially if the person stops smoking.
Chronic Obstructive Pulmonary
Disease
More than 7 million current and former smokers suffer from
chronic obstructive pulmonary disease (COPD), the name used to describe
both chronic bronchitis and emphysema. COPD is the fourth leading cause
of death in America. More women die from COPD than men. Smoking is the
main risk factor for COPD. About 80% to 90% of COPD deaths are caused
by smoking. The late stage of chronic lung disease is one of the most
miserable of all medical conditions. It creates a feeling of gasping
for breath all the time -- much like the feeling of drowning.
Why do smokers have "smoker's
cough?"
Cigarette smoke has chemicals that irritate the air passages
and lungs. When a smoker inhales these substances, the body tries to
protect itself by making mucus and coughing. The early morning smokers
cough happens for many reasons. Normally, tiny hair-like formations
(called cilia) beat outward and sweep harmful material out of the
lungs. Cigarette smoke slows the sweeping action, so some of the
poisons in the smoke stays in the lungs and mucus stays in the airways.
While a smoker sleeps, some cilia recover and begin working again.
After waking up, the smoker coughs because the lungs are trying to
clear away the poisons that built up the previous day. The cilia will
completely stop working after they have been exposed to smoke for a
long time. Then the smoker's lungs are even more exposed and
susceptible than before, especially to bacteria and viruses in the air.
If you smoke but don't inhale,
is there any danger?
Yes. Wherever smoke touches living cells, it does harm. Even
if smokers don't inhale they are breathing the smoke as secondhand
smoke and are still at risk for lung cancer. Pipe and cigar smokers,
who often don’t inhale, are at an increased risk for lip, mouth,
tongue, and some other cancers.
Does cigarette smoking affect
your heart?
Yes. Smoking cigarettes increases the risk of heart disease,
which is the number one cause of death in the United States. Smoking,
high blood pressure, high cholesterol, physical inactivity, obesity,
and diabetes are all risk factors for heart disease, but cigarette
smoking is the biggest risk factor for sudden death from a heart
attack. Smokers who have a heart attack are more likely to die within
an hour of the heart attack than non-smokers. Cigarette smoke can harm
the heart at very low levels, even when the amount is too low to cause
lung disease.
How does smoking affect pregnant
women and their babies?
Pregnant women who smoke risk the health and lives of their
unborn babies. Smoking during pregnancy is linked with a greater chance
of miscarriage, premature delivery, stillbirth, infant death, low
birth-weight, and sudden infant death syndrome (SIDS). Up to 5% of
infant deaths would be prevented if pregnant women did not smoke.
When a pregnant woman smokes, she's smoking for two. The
nicotine, carbon monoxide, and other harmful chemicals enter her
bloodstream, pass directly into the baby's body, and keep it from
getting vital nutrients and oxygen it needs for growth.
Breast-feeding is a good way to feed a new baby, but if the
mother smokes it exposes the baby to nicotine and other poisons in the
smoke through breast milk. Nicotine could cause many unwanted symptoms
in the baby, such as restlessness, a rapid heartbeat, vomiting, or
diarrhea.
Some research has also suggested that children whose mothers
smoked while pregnant or who have been exposed to secondhand smoke,
even in small amounts, may be slower learners in school. They may be
shorter and smaller than children of non-smokers. They are also more
likely to smoke when they get older.
What are some of the short- and
long-term effects of smoking cigarettes?
Smoking causes many types of cancer, which may not develop for
years. But cancers account for only about half of the deaths linked to
smoking. Long-term, smoking is also a major cause of heart disease,
aneurysms, bronchitis, emphysema, and stroke, and it makes pneumonia
and asthma worse. Wounds take longer to heal and the immune system may
be less effective in smokers than in non-smokers. Smoking also damages
the arteries. Because of this, many vascular surgeons refuse to operate
on patients with peripheral artery disease (poor blood circulation in
the arms and legs) unless they stop smoking. And male smokers have a
higher risk of sexual impotence (erectile dysfunction) the longer they
smoke
The truth is that cigarette smokers die younger than
non-smokers. In fact, according to a study from the Centers for Disease
Control and Prevention (CDC) done in the late 1990s, smoking shortened
male smokers' lives by 13.2 years and female smokers' lives by 14.5
years. Men and women who smoke are much more likely to die during
middle age (between the ages of 35 and 69) than those who have never
smoked.
Smoking also causes many short-term effects, such as poor lung
function. Because of this, smokers often suffer shortness of breath and
nagging coughs. They often will tire easily during physical activity.
Some other common short-term effects include less ability to smell and
taste, premature aging of the skin, bad breath, and stained teeth
What are the chances that
smoking will kill you?
About half of all the people who continue to smoke will die
because of the habit. In the United States, tobacco causes nearly 1 in
5 deaths, killing about 440,000 Americans each year. Smoking is the
single most preventable cause of death in our society.
Based on current patterns, smoking will kill about 650 million
people alive in the world today. If these patterns continue,
tobacco-caused deaths worldwide are expected to increase from about 5
million per year today to about 10 million per year by the 2030s. Most
of these deaths will happen in developing countries.
What are the dangers of
environmental tobacco smoke?
Environmental tobacco smoke (ETS), also known as passive
smoking or secondhand smoke, occurs when non-smokers breathe in other
people’s tobacco smoke. This includes mainstream smoke (smoke that is
inhaled and then exhaled into the air by smokers) and sidestream smoke
(smoke that comes directly from the burning tobacco in cigarettes). ETS
contains the same harmful chemicals as the smoke that smokers inhale.
In fact, because sidestream smoke is formed at lower temperatures, it
has even larger amounts of some toxic and cancer-causing substances
than mainstream smoke.
There is strong evidence that ETS causes serious damage to
human health. ETS causes about 3,000 lung cancer deaths and about
35,000 deaths from heart disease each year in healthy non-smokers who
live with smokers. It can also affect non-smokers by causing asthma and
other respiratory problems, eye irritation, headaches, nausea, and
dizziness. Children whose parents smoke are more likely to suffer from
asthma, pneumonia, bronchitis, ear infections, coughing, wheezing, and
increased mucus production. Babies of parents who smoke have a greater
chance of dying of sudden infant death syndrome (SIDS). Pregnant women
exposed to ETS are at risk for having a low birth weight baby and may
also be at risk for pre-term delivery and miscarriage.
Breast Cancer
An issue that continues to be an active focus of scientific
research is whether secondhand smoke may increase the risk of breast
cancer. Both mainstream and secondhand smoke have about 20 chemicals
that, in high concentrations, cause breast cancer in rodents. Chemicals
in tobacco smoke reach breast tissue and are found in breast milk.
The evidence about secondhand smoke and breast cancer risk in
human studies is controversial, at least in part because the risk has
not been shown to be increased in active smokers. One possible
explanation for this is that tobacco smoke may have different effects
on breast cancer risk in smokers and in those who are just exposed to
smoke.
A report from the California Environmental Protection Agency
in 2005 concluded that the evidence regarding secondhand smoke and
breast cancer is "consistent with a causal association" in younger,
mainly premenopausal women. The 2006 US Surgeon General's report, The Health Consequences of
Involuntary Exposure to Tobacco Smoke, concluded that
there is "suggestive but not sufficient" evidence of a link at this
point. In any case, women should be told that this possible link to
breast cancer is yet another reason to avoid contact with secondhand
smoke.
Am I at risk for getting lung
cancer from smoke odors on clothing or from being in a room where
people have been smoking?
There are no reports in the medical literature of research on
the cancer-causing effects of cigarette odors, but the literature shows
that secondhand smoke can seep into hair, clothing, and other surfaces.
The unknown cancer-causing effects would probably be minimal compared
to direct secondhand smoke exposure, such as living in a household that
has a smoker.
What is being done to protect
people from the hazards of smoking?
Tobacco Labels
Both the public and private sectors have acted to help
decrease smoking-related deaths and illnesses in this country. Since
1966, the US Surgeon General's health warnings have been required on
all cigarette packages and, since 1987, on all spit or oral tobacco
products. Since 2001, the 7 major cigar manufacturers in the United
States have provided 5 health warnings that rotate on cigar labels.
These labels are much like those on cigarette packages.
Advertising
Congress banned cigarette advertising on TV and radio in 1971
and spit tobacco advertising in 1987. The American Legacy Foundation
and many states have made anti-smoking public service messages that are
featured on television, radio, and billboards.
Taxes
Taxes on cigarettes have risen in many states in recent years.
They have been shown to discourage young people from starting to smoke
and to encourage smokers to quit. State taxes on tobacco vary from as
low as 7 cents (in South Carolina) to up to $2.58 a pack (in New
Jersey).
Smoking Bans
Laws in all 50 states and the District of Columbia restrict or
do not allow smoking in certain public places. These laws range from
simple restrictions, such as designated areas in government buildings,
to laws that ban smoking in all public places and workplaces. Many
federal worksites, including the White House, are smoke-free. Smoking
is also banned on all domestic airplane flights.
Are menthol cigarettes safer
than other brands?
Menthol cigarettes are not safer than any other brand. In
fact, they may even be more dangerous. About one-fourth of all
cigarettes sold in the United States are flavored with menthol. These
cigarettes are especially popular among African Americans. The added
menthol produces a cooling sensation in the throat when the smoke is
inhaled. It also decreases the cough reflex and covers the dry feeling
in the throat that smokers often have. People who smoke menthol
cigarettes can inhale deeper and hold the smoke in longer.
A recent study showed that people who smoke menthol cigarettes
are less likely to try to quit and are less likely to be successful
when they do try. This study proposed that menthol smokers might want
to switch to non-menthol cigarettes before trying to quit in order to
improve their chances of quitting smoking.
Are spit tobacco and snuff safe
alternatives to cigarette smoking?
There are many terms used to describe tobacco that is put in
the mouth , such as spit, oral, smokeless, chewing, and snuff tobacco.
The use of any kind of spit or smokeless tobacco is a major health
risk. It is a less lethal substitute for smoking cigarettes but, less
lethal is a far cry from safe.
The amount of nicotine absorbed is usually more than the
amount delivered by a cigarette. Overall, people who dip or chew get
about the same amount of nicotine as regular smokers. The most harmful
cancer-causing substances in spit tobacco are tobacco-specific
nitrosamines which have been found at levels 100 times higher than the
nitrosamines that are allowed in bacon, beer, and other foods. These
carcinogens cause lung cancer in experimental animals, even when
injected, not inhaled.
The juice from the smokeless tobacco is absorbed directly
through the lining of the mouth. This causes sores and white patches
(called leukoplakia) that often lead to cancer of the mouth.
People who use spit and other types of smokeless tobacco
greatly increase their risk of other cancers including those of the
pharynx (throat). Other effects of spit tobacco use include chronic bad
breath, stained teeth and fillings, gum disease, tooth decay, tooth
loss, tooth abrasion, and loss of bone in the jaw. Users may also have
problems with high blood pressure and may be at increased risk for
heart disease.
What is snus? Is it safe?
Snus (sounds like "snoose") is a type of moist snuff first
used in Sweden. It is often flavored with spices or fruit, and is
usually packaged in thin bags much like tea bags. It is also sold
loose, as a moist powder. Like snuff and other spit tobaccos, snus is
held between the gum and mouth tissues where the juice is absorbed into
the body.
Because it is heated during processing, Swedish snus has fewer
tobacco-specific nitrosamines (see previous question) that are known to
cause cancer. Snus users in Sweden have lower rates of several types of
cancer than Swedish smokers. Because of this, some people believe snus
is "safe." However, snus users have a higher risk of cancer of the
pancreas than non-users. They also get sores or spots in the mouth
(lesions) where the snus is held. It appears that snus users may have
mouth cancer more often than non-users, though more study needs to be
done to confirm this.
Since US tobacco sellers are not required to list what is in
their products, it would be hard to know how the US versions of snus
might compare to the Swedish versions without doing studies here. Since
snus has just been introduced, it is uncertain what other problems it
might cause.but, snus is not a safe alternative to smoking.
What are the health risks of
smoking pipes or cigars?
Many people view cigar smoking as more "civilized" and
"sophisticated," as well as less dangerous than cigarette smoking. Yet
a single large cigar can contain as much tobacco as an entire pack of
cigarettes.
Most of the same cancer-causing substances found in cigarettes
are found in cigars. Most cigars have as much nicotine as several
cigarettes. When cigar smokers inhale, nicotine is absorbed as quickly
as it is with cigarettes. For those who do not inhale, it is absorbed
more slowly through the lining of the mouth. Both inhaled and
non-inhaled nicotine are highly addictive.
Smoking cigars causes cancers of the lung, oral cavity (lip,
tongue, mouth, throat), larynx (voice box), esophagus (swallowing
tube), and probably cancers of the bladder and pancreas. Cigar smokers
have a greater risk of dying from cancer of the mouth, larynx, or
esophagus than non-smokers. The risk of death from lung cancer is not
as high as it is for cigarette smokers, but is still many times higher
than the risk for non-smokers.
Cigar smokers who inhale deeply and smoke several cigars a day
are also at increased risk for heart disease and chronic lung disease.
Pipe smokers have an increased risk of dying from cancers of
the lung, throat, esophagus, larynx, pancreas, and colon and rectum.
They also have an increased risk of dying of heart disease, stroke, and
chronic lung disease. The level of these risks seems to be about the
same as that for cigar smokers.
Smoking cigars or pipes is not a safe alternative to smoking
cigarettes.
What about more "exotic" forms
of smoking tobacco, such as clove cigarettes, bidis, and hookahs?
Many forms of flavored tobacco have become popular in recent
years, especially among younger people. Clove cigarettes (kreteks),
bidis, and, more recently, hookahs, often appeal to those who want
something a little different. They also give young people another way
to experiment with tobacco. The false image of these products as clean,
natural, and safer than regular cigarettes seems to attract some young
people who may otherwise not start smoking. But these products carry
many of the same risks of cigarettes and other tobacco products and
each has its own additional problems linked to it.
Clove Cigarettes
Clove cigarettes, also called kreteks, are imported mainly
from Indonesia and contain 60% to 70% tobacco and 30% to 40% ground
cloves, clove oil, and other additives. The chemicals in cloves have
been linked to asthma and other lung diseases.
Users often have the mistaken notion that smoking clove
cigarettes is a safe alternative to smoking tobacco. But they are a
tobacco product with the same health risks as cigarettes. In fact, they
have been shown to deliver more nicotine, carbon monoxide, and tar than
regular cigarettes.
Bidis
Bidis or "beedies" are flavored cigarettes imported mainly
from India. They are hand-rolled in an unprocessed tobacco leaf and
tied with colorful strings on the ends. Their popularity has grown in
recent years in part because they come in many candy-like flavors such
as strawberry, vanilla, and grape, they usually cost less than regular
cigarettes, and they often give the smoker an immediate buzz.
Even though bidis contain less tobacco than regular
cigarettes, they deliver higher levels of nicotine (the addictive
chemical in tobacco) and other harmful substances such as tar and
carbon monoxide. Because they are thinner than regular cigarettes, they
require about 3 times as many puffs per cigarette. They are also
unfiltered. Bidis appear to have all of the same health risks of
regular cigarettes, if not more. Bidi smokers have much higher risks of
heart attacks, chronic bronchitis, and some cancers than non-smokers.
Hookah
Hookah (or narghile) smoking, started in the Middle East,
Users burn flavored tobacco (called shisha) in a water pipe and inhale
the smoke through a long hose. It has recently become popular among
young people, especially around college campuses. Hookah smoking is
usually a social event that allows the smokers to spend time together
and talk as they pass the pipe around. It is marketed as being a safe
alternative to cigarettes because the percentage of tobacco in the
product smoked is low. This claim for safety is false. The water does
not filter out many of the toxins. In fact, hookah smoke contains more
toxins such as nicotine, carbon monoxide, tar, and other hazardous
substances than cigarette smoke. Several types of cancer have been
linked to hookah smoking. Hookah use is also linked to other unique
risks not linked with cigarette smoking. For example, infectious
diseases can be spread by sharing the pipe or through the way the
tobacco is prepared.
All forms of tobacco are dangerous. Even if the health risks
were smaller for some tobacco products as opposed to others, all
tobacco products contain nicotine, which can lead to increased use and
addiction. Tobacco cannot be considered safe in any amount or form.
What can I do to help with any
damage that may have occurred because of smoking?
If you have used tobacco in any form, now or in the past, tell
your health care provider so he or she can be sure that you have
appropriate preventive health care. It is well known that tobacco use
puts you at risk for certain health-related illnesses. This means part
of your health care should focus on related screening and preventive
measures to help you stay as healthy as possible. For example, you will
want to be sure that you regularly check the inside of your mouth for
any changes and have an oral exam by your doctor or dentist if you find
any changes or problems. The American Cancer Society recommends that
periodic check-ups should include oral cavity (mouth) exams. By doing
this tobacco users may be able to find oral changes and leukoplakia
(white patches on the mouth membranes) early. This may help prevent
oral cancer.
You should also be aware of any of the following:
-
any change in a cough (for example, you cough up more
mucus than usual)
-
a new cough
-
coughing up blood
-
hoarseness
-
trouble breathing
-
wheezing
-
headaches
-
chest pain
-
loss of appetite
-
weight loss
-
general fatigue (feeling tired all the time)
-
repeated respiratory infections
Any of these could be signs of lung cancer or a number of
other lung conditions and you should report any symptom to your doctor
as soon as possible. Although these can be signs of a problem, many
lung cancers do not cause any noticeable symptoms until they are
advanced and have spread to other parts of the body.
Remember that tobacco users have an increased risk for other
cancers too, depending on the way they use tobacco. You can learn more
about the types of cancer you may be at risk for by reading the
American Cancer Society document that discusses the way you use tobacco
(i.e., Cigar
Smoking). Other risk factors for these cancers may
be more
important than your use of tobacco, but you should know the additional
risks that might apply to you.
If you have any health concerns that may be related to your
tobacco use, please see your health care provider as soon as possible.
Taking care of yourself and getting treatment for small problems will
give you the best chance for successful treatment. The best way,
though, to take care of yourself and decrease your risk for
life-threatening lung problems is to quit using tobacco.
How does tobacco use affect the
economy?
The tobacco industry is one of the most profitable businesses
in the country, making billions of dollars every year. But the costs of
smoking are far higher than the income from cigarette sales.
-
Smoking causes more than $167 billion each year in
health-related costs, including the cost of lost productivity caused by
deaths from smoking.
-
Smoking-related medical costs totaled more than
$75.5 billion in 1998 and accounted for 8% of personal health care
medical expenditures.
-
Death-related productivity losses from smoking
among workers cost the US economy more than $92 billion yearly (average
for 1997-2001).
-
For each pack of cigarettes sold in 1999, $3.45 was
spent on medical care caused by smoking, and $3.73 lost in
productivity, for a total cost to society of $7.18 per pack.
Can quitting really help a
lifelong smoker?
Yes. It is never too late to quit using tobacco. The sooner
smokers quit, the more they can reduce their chances of getting cancer
and other diseases. Within minutes of smoking the last cigarette, the
body begins to restore itself.
20 minutes After
Quitting
Your heart rate and blood pressure drop.
(Effect of Smoking on Arterial Stiffness and Pulse Pressure
Amplification, Mahmud, A, Feely, J. 2003. Hypertension:41:183.)
12 hours After
Quitting
The carbon monoxide level in your blood drops to normal.
(US Surgeon General's
Report, 1988, p. 202)
2 weeks to 3
Months After Quitting
Your circulation improves and your lung function increases.
(US Surgeon General's
Report, 1990, pp.193, 194,196, 285, 323)
1 to 9 Months
After Quitting
Coughing and shortness of breath decrease; cilia (tiny hair-like
structures that move mucus out of the lungs) regain normal function in
the lungs, increasing the ability to handle mucus, clean the lungs, and
reduce the risk of infection.
(US Surgeon General's
Report, 1990, pp. 285-287, 304)
1 Year After
Quitting

Are there some benefits of
quitting that I'll notice right away?
Kicking the tobacco habit offers some benefits that you'll
notice right away and some that will develop slowly over time. These
benefits can improve your day-to-day life a lot.
-
Food will taste better.
-
Your sense of smell returns to
normal.
-
Your breath, hair, and clothes smell better.
-
Your teeth and fingernails stop yellowing.
-
Ordinary activities no longer leave you out of breath (for
example,
climbing stairs or doing light housework).
Quitting also helps stop the damaging effects of tobacco on
how you look, including premature wrinkling of your skin and gum
disease.
Suppose I smoke for a while and
then quit?
Smoking begins to cause damage right away and is highly
addictive. Some studies have found nicotine to be as addictive as
heroin, cocaine, or alcohol. It’s the most common form of drug
addiction in the United States. It’s much better to never start smoking
cigarettes -- and become addicted to nicotine -- than it is to smoke
with the thought of quitting later. Like alcohol, heroin, and cocaine,
nicotine creates a tolerance in the body. This makes it hard to quit,
but with the right support it can be done.
When an ex-smoker smokes a cigarette, even years after
quitting, the body reacts in the same way as it did when the person was
smoking, which can cause the person to want to smoke again. Don't think
you can smoke for a short while and quit when you want to; it's seldom
that easy.
How do people quit smoking?
Quitting smoking is not easy, and some people try many times
before succeeding. There are many ways to quit smoking. For example,
some have been successful by stopping "cold turkey," by taking part in
the Great American Smokeout®, or by using other
methods.
There's no single best way to quit. Quitting for good may mean
using many methods, including step-by-step manuals, self-help classes
or counseling, toll-free telephone-based counseling programs, and/or
using medicines like nicotine replacement therapies (see next
question). Smokers may also need to make changes in their daily routine
to help them break their smoking habits.
What are nicotine replacement
therapies?
Nicotine replacement therapies (NRTs) are medicines that help
decrease or stop a smoker's withdrawal symptoms by giving controlled
doses of nicotine without the other harmful chemicals of cigarette
smoke. NRTs are available as patches, gums, inhalers, nasal sprays, or
lozenges. The Food and Drug Administration (FDA) has approved all of
these products to help people quit smoking. Patches, gums, and lozenges
are available over-the-counter, but you will need a doctor’s
prescription for inhalers and nasal sprays.
These products work by helping smokers control their physical
responses as they quit. For best results, smokers should use NRTs along
with behavioral change programs that are designed to help smokers break
their psychological (mental) dependence on cigarettes. For more
information on such programs, call the American Cancer Society at
1-800-ACS-2345.
Not everyone can use nicotine replacement therapy. People with
certain medical conditions and pregnant women should use it only with a
doctor's supervision. It is always a good idea to get your doctor's
input and support when you decide to quit smoking.
The best time to start NRT is when you begin to try to quit.
Many smokers ask if it is possible to start a program of nicotine
replacement while you are still smoking. There is some research on
smokers using NRT while still smoking, but the results are still too
early to say for certain if this is dangerous to your health. The most
important thing is to make sure that you are not overdosing on
nicotine, which can affect your heart and blood circulation. It is
safest to be under a doctor's care if you wish to try smoking and using
NRT while you are tapering cigarette smoking.
For more information, see the American Cancer Society
document, Guide
to Quitting Smoking.
Are there other medicines or
vaccines to help smokers quit?
Yes. Some medicines that don't have nicotine have already been
approved to help with quitting smoking.
Bupropion (Zyban®), was first used as
an antidepressant, and later approved by the FDA to help people quit
smoking. This medicine does not contain nicotine and is available only
with a doctor's prescription. It affects chemicals in the brain that
are related to nicotine craving. It can be used alone or together with
nicotine replacement.
Newer medicines may help smokers (or former smokers) by
stopping them from getting physical pleasure from smoking. The
medicines seem to work by stopping nicotine from stimulating the brain,
either by blocking the brain receptors that nicotine normally attaches
to, or preventing it from reaching the brain altogether (as in the case
of the vaccines -- see below).
One such medicine, varenicline (Chantix®),
is FDA-approved for help with quitting. Varenicline is a pill taken
twice a day. Once in the body, it attaches to nicotine receptors in the
brain, reducing the pleasurable effects of smoking and helping to
reduce nicotine withdrawal symptoms. Many studies have shown
varenicline can more than double the chances of quitting smoking.
Because varenicline is a newer drug, there is no research supporting
its safety in using it with nicotine replacement products at the same
time.
Other medicines still being studied include rimonabant, which
is also a pill, and vaccines that are given as a series of injections.
Early tests of these new treatments have been promising. They seem to
be safe, and may help some smokers quit or stay quitters. But larger
studies are needed to show these treatments are effective before the
FDA can approve them for use. Many large studies of these treatments
are now under way. If they prove effective, one or more of these drugs
could be approved within the next few years.
It is not likely that any one of these drugs will work in
every person, however, and using different quitting aids at the same
time is still the best way to increase your chances of success. For
more information on quitting and medicines that can be used, see Guide
to Quitting Smoking.
Where can I go for help?
It is hard to stop smoking, but you can do it! About 45.7
million Americans have quit smoking for good, and now there are more
former smokers than current smokers. Many organizations offer
information, counseling, and other services on how to quit, as well as
information on where to go for help. Other good resources for finding
help include your doctor, dentist, local hospital, or employer.
