Tobacco smoke is enormously harmful to your health. There’s no safe way
to smoke. Replacing your cigarette with a cigar, pipe, or hookah won’t help you
avoid the health risks associated with tobacco products.
Cigarettes contain about 600 ingredients. When they
burn, they generate more than 7,000 chemicals, according to the American Lung Association. Many of those chemicals are
poisonous and at least 70 of them can cause cancer. Many of the same
ingredients are found in cigars and in tobacco used in pipes and hookahs.
Cigars have a higher level
of carcinogens, toxins, and tar than cigarettes.
When using a hookah pipe, you’re likely to inhale more
smoke than you would from a cigarette. Hookah smoke has many toxic compounds
and exposes you to more carbon monoxide than cigarettes do. Hookahs also
produce more secondhand smoke. Smoking is one of the leading causes of preventable death.
NICOTINE
One of the ingredients in tobacco is a mood-altering drug called nicotine.
Nicotine reaches your brain in mere seconds. It’s a central nervous system
stimulant, so it makes you feel more energized for a little while. As that
effect subsides, you feel tired and crave more. Nicotine is habit forming.
Smoking increases risk of macular degeneration, cataracts,
and poor eyesight. It can also weaken your sense of taste and sense of smell,
so food may become less enjoyable.
Your body has a stress hormone called corticosterone,
which lowers the effects of nicotine. If you’re under a lot of stress, you’ll
need more nicotine to get the same effect.
Physical withdrawal from smoking can impair your
cognitive functioning and make you feel anxious, irritated, and depressed.
Withdrawal can also cause headaches and sleep problems.
When you inhale smoke, you’re taking in substances that can damage your
lungs. Over time, your lungs lose their ability to filter harmful chemicals.
Coughing can’t clear out the toxins sufficiently, so these toxins get trapped
in the lungs. Smokers have a higher risk of respiratory infections, colds, and
flu.
In a condition called emphysema, the air sacs in your
lungs are destroyed. In chronic bronchitis, the lining of the tubes of the
lungs becomes inflamed. Over time, smokers are at increased risk of developing
these forms of chronic obstructive pulmonary disease (COPD). Long-term smokers
are also at increased risk of lung cancer.
Withdrawal from tobacco products can cause temporary
congestion and respiratory pain as your lungs begin to clear out.
Children whose parents smoke are more prone to
coughing, wheezing, and asthma attacks than children whose parents don’t. They
also tend to have more ear infections. Children of smokers have higher rates of
pneumonia and bronchitis.
DIGESTIVE SYSTEM
Smokers are at great risk of developing oral problems. Tobacco use can
cause gum inflammation (gingivitis) or infection (periodontitis). These
problems can lead to tooth decay, tooth loss, and bad breath.
Smoking also increases risk of cancer of the mouth,
throat, larynx, and esophagus. Smokers have higher rates of kidney cancer and
pancreatic cancer. Even cigar smokers who don’t inhale are at increased risk of
mouth cancer.
Smoking also has an effect on insulin, making it more
likely that you’ll develop insulin resistance. That puts you at increased risk
of type 2 diabetes. When it comes to diabetes, smokers tend to develop
complications at a faster rate than nonsmokers.
Smoking also depresses appetite, so you may not be
getting all the nutrients your body needs. Withdrawal from tobacco products can
cause nausea.
SEXUALITY
Restricted blood flow can affect a man’s ability to get an erection.
Both men and women who smoke may have difficulty achieving orgasm and are at
higher risk of infertility. Women who smoke may experience menopause at an
earlier age than nonsmoking women. Smoking increases a woman’s risk of cervical
cancer.
Smokers experience more complications of pregnancy,
including miscarriage, problems with the placenta, and premature delivery.
Pregnant mothers who are exposed to secondhand smoke
are also more likely to have a baby with low birth weight. Babies born to
mothers who smoke while pregnant are at greater risk of low birth weight, birth
defects, and sudden infant death syndrome (SIDS). Newborns who breathe
secondhand smoke suffer more ear infections and asthma attacks.
AUTOIMMUNE DISEASE
The immune system is the body’s way of protecting itself from
infection and disease. Smoking compromises the immune system, making smokers
more likely to have respiratory infections.
Smoking also
causes several autoimmune diseases, including Crohn’s disease and rheumatoid
arthritis. It may also play a role in periodic flare-ups of signs and symptoms
of autoimmune diseases. Smoking doubles your risk of developing rheumatoid
arthritis.
SMOKING AND CANCER
Smoking can cause cancer
almost anywhere in your body:
·
Bladder
·
Blood (acute myeloid
leukemia)
·
Cervix
·
Colon and rectum
(colorectal)
·
Esophagus
·
Kidney and ureter
·
Larynx
·
Liver
·
Oropharynx (includes
parts of the throat, tongue, soft palate, and the tonsils)
·
Pancreas
·
Stomach
·
Trachea, bronchus, and
lung
Smoking also increases the risk of dying from cancer and other diseases in cancer patients and survivors
