Smoking is one of the worst things kids or adults can do to their bodies. Yet every single day nearly 4,400 kids between the ages 12 and 17 start smoking. Why? There's more than just one simple answer. Some kids may start smoking just because they're curious. Others may like the idea of doing something dangerous - something grown-ups don't want them to do. Still others might have grown up around lots of people who smoke and they might think it's the way to act like an adult.
You've probably heard that smoking and tobacco use can cause cancer and heart disease. That's true, but sometimes kids can't really think that far into the future to worry about an illness they might not get for 20 years. So let's talk about the problems that might affect kids more quickly:
bad breath
yellow teeth
smelly clothes
more colds and coughs
difficulty keeping up with friends when playing sports
empty wallet - cigarettes and tobacco products are very expensive!
Let's find out more about cigarettes and tobacco.
What Are Smoking and Smokeless Tobacco?
Tobacco (say: tuh-ba-ko) is a plant that can be smoked in cigarettes, pipes, or cigars. It's the same plant that's in smokeless tobacco, known as dip, chew, snuff, spit, or chewing tobacco. Smokeless tobacco is not lit and breathed in like tobacco in cigarettes, pipes, and cigars. Instead, smokeless tobacco is put between the lip and gum and sucked on inside the mouth.
Tobacco contains nicotine (say: nih-kuh-teen), a chemical that causes a tingly or good feeling - but that feeling only lasts for a little while. Nicotine is also addictive (say: uh-dik-tiv). That means that if you start to use nicotine, your body and mind will become so used to it that you'll need to have it just to feel OK.
Anyone who starts smoking could become addicted to it. If you're addicted to something, it's very hard to stop doing it, even if you want to. That's why so many adults have a hard time quitting smoking.
Why Is It So Bad for You?
Cigarettes and smokeless tobacco kill hundreds of thousands of Americans every year. You know those rubber bracelets that were created to bring attention to different causes? The Campaign for Tobacco-Free Kids created a red one with the number 1,200 on it. Why 1,200? That's the number of people who die each day due to smoking.
The nicotine and other poisonous chemicals in tobacco cause lots of diseases, like heart problems and some kinds of cancer. If you smoke, you hurt your lungs and heart each time you light up. It also can make it more difficult for blood to move around in the body, so smokers may feel tired and cranky. The longer you smoke, the worse the damage becomes.
The Other Cost of Smoking
Using tobacco eats up a lot of money, too. A pack of cigarettes costs $4, on average. That means, even if you buy just one pack a week, you'll spend $208 in a year. Some people smoke a pack a day, which adds up to $1,460! That's a lot of CDs, computer games, and clothes.
What's It Like?
Usually, people don't like smoking or chewing tobacco at first. Your body is smart, and it knows when it's being poisoned. When people try smoking for the first time, they often cough a lot and feel pain or burning in their throat and lungs. This is your lungs' way of trying to protect you and tell you to keep them smoke free. Also, many people say that they feel sick to their stomachs or even throw up. If someone accidentally swallows chewing tobacco, they may be sick for hours. Yuck.
What if My Friend Smokes?
If you have a friend who smokes or uses tobacco, you can help him or her by encouraging the person to quit. Here are some reasons you can mention:
It will hurt his or her health.
It will make his or her breath stinky.
It will turn his or her teeth yellow.
It will give him or her less endurance when running or playing sports.
It's expensive.
It's illegal to buy cigarettes when you're underage.
If you think it will help, you could print out articles like this one for your friend. He or she may be interested in learning more about the dangers of smoking. But the person also could be a little angry. No one likes to hear that they're doing something wrong. If your friend gets upset, don't push it too much. In time, he or she may realize you are right.
In the meantime, it could help to talk with a parent or a school counselor to say you're worried about your friend. When your friend is ready, a grown-up can help him or her quit for good. If your friend decides to quit, support him or her

Smoking, inhalation and exhalation of the fumes of burning tobacco. Leaves of the tobacco plant are smoked in various ways. After a drying and curing process, they may be rolled into cigars or shredded for insertion into smoking pipes. Cigarettes, the most popular method of smoking, consist of finely shredded tobacco rolled in lightweight paper. About 46 million people in the United States smoke an estimated 420 billion cigarettes each year.
Until the 1940s smoking was considered harmless, but laboratory and clinical research has since confirmed that tobacco smoke presents a hazard to health. Smoke from the average cigarette contains around 4,000 chemicals, some of which are highly toxic and at least 43 of which cause cancer. Nicotine, a major constituent of tobacco smoke, is both poisonous and highly addictive. According to the American Cancer Society, smoking is the most preventable cause of death in America today.
II History
Printer-friendly version of section | Edit this section
European explorers who arrived in the Western Hemisphere in the 1500s observed Native Americans smoking tobacco plant leaves in pipes. The colonists who followed them grew tobacco plants as a cash crop for export, and smoking became part of European culture by the 1600s. Most tobacco was consumed in pipes and cigars or as snuff (finely pulverized tobacco inhaled into the nostrils). This pattern changed by the early 20th century, by which time smokers consumed more than 1,000 cigarettes per capita each year in the United States and some European countries. The general attitude of society was that smoking relieved tension and produced no ill effects. During World War II (1939-1945) American physicians endorsed sending soldiers tobacco, and cigarettes were included in the field ration kits of U.S. armed forces personnel until 1975.
Some scientists noticed, however, that lung cancer, which was rare before the 20th century, had increased dramatically since about 1930. The American Cancer Society and other organizations initiated studies comparing deaths among smokers and nonsmokers over a period of several years. All such studies found increased mortality among smokers, both from cancer and other causes. In addition, experimental studies in animals showed that many of the chemicals contained in cigarette smoke are carcinogenic.

In 1962 the U.S. government appointed a panel of ten scientists to study the available evidence concerning the health effects of smoking. Their conclusions were included in the 1964 surgeon general’s report, which stated that “cigarette smoking is a health hazard of sufficient importance in the United States to warrant appropriate remedial action.” Smoking in adults, measured as an average number of cigarettes smoked per year, began to decline steadily after the 1964 report and has fallen more than 40 percent since 1965.
III Health Effects of Smoking
Printer-friendly version of section | Edit this section
About 442,000 people in the United States die each year from illnesses caused by cigarette smoking. Smoking accounts for nearly 90 percent of lung cancer deaths. Additionally, smokers are at increased risk for cancer of the larynx, oral cavity, esophagus, bladder, kidney, and pancreas.
One-third of smoking-related deaths are caused by coronary heart disease or chronic airway obstruction. Smoking also increases the risk of stroke by 50 percent—40 percent among men and 60 percent among women. Other research has shown that mothers who smoke give birth more frequently to premature or underweight babies, probably because of a decrease in blood flow to the placenta. Babies born to mothers who smoke during pregnancy are also at increased risk for sudden infant death syndrome.
Cigar and pipe smoke contains the same toxic and carcinogenic compounds found in cigarette smoke. A report by the National Cancer Institute concluded that the mortality rates from cancer of the mouth, throat, larynx, pharynx, and esophagus are approximately equal in users of cigarettes, cigars, and pipes. Rates of coronary heart disease, lung cancer, emphysema, and chronic bronchitis are elevated for cigar and pipe smokers and are correlated to the amount of smoking and the degree of inhalation.
Studies have found that cigarettes are addictive because an unknown component of tobacco smoke appears to destroy an important brain enzyme known as monoamine oxidase B (MAO B). The enzyme is vital for breaking down excess amounts of dopamine, a neurotransmitter that triggers pleasure-seeking behavior. Smokers have decreased levels of MAO B and abnormally high levels of dopamine, which may encourage the smoker to seek the pleasure of more tobacco smoke.
Even nonsmokers are at risk from smoking. Recent research has focused on the effects of environmental tobacco smoke (ETS)—that is, the effect of tobacco smoke on nonsmokers who must share the same environment with a smoker. The United States Environmental Protection Agency (EPA) estimates that exposure to ETS, which contains all the toxic agents inhaled by a smoker, causes 3,000 lung cancer deaths and an estimated 35,000 deaths from heart disease per year among nonsmokers. Secondhand smoke can aggravate asthma, pneumonia, and bronchitis, and impair blood circulation.
The smoking habit and addiction to nicotine usually begin at an early age. In the United States, more than 90 percent of adults who smoke started by age 21, and nearly half of them were regular smokers by the age of 18. Despite increasing warnings about the health hazards of smoking and widespread bans on smoking in public places, smoking remains common among teenagers and young adults. In 2001 surveys of students in grades 9 through 12 found that more than 38 percent of male students and nearly 30 percent of female students smoke. Although black teenagers have the lowest smoking rates of any racial group, cigarette smoking among black teens increased 80 percent in the late 1990s. Advertisements aimed at a young audience are largely blamed for this new generation of smokers.
IV Quitting Smoking
Printer-friendly version of section | Edit this section
Studies of former smokers show that their risk of dying from smoking-related disease decreases with each year of abstinence. According to the World Health Organization (WHO), smokers who quit smoking before the age of 50 reduce their risk of life-threatening disease by half after just one year, compared with those who continue smoking.
Other benefits of quitting smoking include more disposable income, admission to social activities and institutions that ban smoking, and often, lower health insurance premiums. Nonetheless, to quit smoking is difficult, most likely because smokers crave the effect of the nicotine in the smoke. The U.S. surgeon general declared nicotine an addictive drug comparable to other addictive substances, including cocaine, heroin, and alcohol, in its ability to induce dependence. Overall, tobacco smoking causes about 20 times the number of deaths in the United States than all other addictive drugs combined.
Smoking cessation methods are plentiful, and many books and products are available to help an individual stop smoking. Many smokers turn to group help because of the support and understanding provided by other former smokers or people trying to quit. Most successful group-help techniques involve a challenge and reward system that also bolsters the self-discipline of the former smoker.
A number of nicotine replacement products are available to help a person quit smoking. Nicotine patches are small, nicotine-containing adhesive disks that must be applied to the skin. The nicotine is slowly absorbed through the skin and enters the bloodstream. Over time, a smoker uses nicotine patches containing smaller and smaller doses of nicotine until eventually the craving for nicotine ends. Nicotine gum works in a similar manner, providing small doses of nicotine when chewed. A nicotine nasal spray is a physician-prescribed spray that relieves cravings for a cigarette by delivering nicotine to the nasal membranes. Also available by prescription, the nicotine inhaler looks like a cigarette; when puffed, the inhaler releases nicotine into the mouth.
An approach combining three different smoking cessation therapies has found remarkable success. This approach combines an antidepressant drug called bupropin, marketed under the brand name Zyban, with a nicotine replacement product and counseling. While less than 25 percent of smokers who use nicotine replacement products alone remain smoke-free for more than a year, 40 to 60 percent of smokers using this combination approach achieved this milestone.

In the United States, the first direct action to curb smoking after the U.S. surgeon general’s 1964 report on smoking was the mandate of a warning on cigarette packages by the Federal Trade Commission. This warning took effect in 1964 and was strengthened in 1969 to read: “Warning: The Surgeon General Has Determined That Cigarette Smoking Is Dangerous to Your Health.” A stronger sequence of four alternative warnings was developed in 1984. In 1971 all cigarette advertising was banned from radio and television, and cities and states passed laws requiring nonsmoking sections in public places and workplaces.
This trend has continued and smoking is now banned at the federal and state levels in most government buildings and in many private businesses. As of February 1990 federal law banned smoking on all domestic United States airline flights under six hours in duration. By 1998 more than 90 percent of nonstop flights between the United States and all foreign countries were also smoke free.
In 2002 President George W. Bush signed into law the Safe and Drug-Free Schools and Communities Act. The law bans smoking within any indoor facility used for childhood education. By 2003 a number of states (including New York, Connecticut, Maine, and California) and cities (including Boston, Massachusetts and Austin, Texas) passed laws banning smoking in all bars, restaurants, and clubs.
The tobacco industry has been increasingly criticized for its role in encouraging smoking, particularly in young people. Various lawsuits have been brought against tobacco companies to reclaim damages due to disease or death associated with smoking. The first major successful suit occurred in March 1996 when the Liggett Group, a consortium of companies, agreed to pay damages to five states. An onslaught of litigation against the tobacco industry followed. In part to avoid potentially ruinous lawsuits filed by states, in 1998 the tobacco industry and attorneys general from 46 U.S. states agreed to a $206-billion settlement. The settlement, to be paid over 25 years, will be used to compensate states for the costs of treating smoking-related illness, to finance nationwide antismoking programs, and to underwrite health care for uninsured children.

The tobacco industry must also contend with a barrage of lawsuits filed by individual smokers and their families seeking damages for smoking-related health problems and deaths. Across the United States, such lawsuits have had mixed results. In several cases, juries have cleared the tobacco companies of all responsibility. While several other cases have resulted in large awards for the plaintiffs, few hold up under the appeals process.
Tobacco industry representatives long denied that nicotine is addictive and that there is a link between smoking and poor health. In recent years, however, cigarette makers have faced increased pressure from smoking-related lawsuits and federal regulators to accept prevailing scientific opinions about the health risks of smoking. In late 1999 Philip Morris, now known as Altria, the nation’s largest cigarette maker, publicly acknowledged that smoking is addictive and causes serious health problems. This latest admission was considered a way to make it more difficult for those who have recently started smoking to claim they were unaware of the dangers if they choose to sue cigarette companies. In 2003 an Illinois judge ordered Philip Morris to pay $10.1 billion in damages for using misleading advertising campaigns suggesting that cigarette brands marketed as “low tar” or “light” are safer than regular brands. Numerous scientific studies prove that the use of low-tar cigarettes do not reduce the risk of developing smoking-related disease, and the judge found that Philip Morris intentionally disregarded consumer rights by spreading disinformation.

Nicotine: A Powerful Addiction
If you have tried to quit smoking, you know how hard it can be. It is hard because nicotine is a very addictive drug. For some people, it can be as addictive as heroin or cocaine.
Quitting is hard. Usually people make 2 or 3 tries, or more, before finally being able to quit. Each time you try to quit, you can learn about what helps and what hurts.
Quitting takes hard work and a lot of effort, but you can quit smoking.
--------------------------------------------------------------------------------
Good Reasons for Quitting
Quitting smoking is one of the most important things you will ever do.
You will live longer and live better.
Quitting will lower your chance of having a heart attack, stroke, or cancer.
If you are pregnant, quitting smoking will improve your chances of having a healthy baby.
The people you live with, especially your children, will be healthier.
You will have extra money to spend on things other than cigarettes.
--------------------------------------------------------------------------------
Five Keys for Quitting
Studies have shown that these five steps will help you quit and quit for good. You have the best chances of quitting if you use them together.
1. Get ready.
2. Get support.
3. Learn new skills and behaviors.
4. Get medication and use it correctly.
5. Be prepared for relapse or difficult situations.
1. Get Ready
Set a quit date.
Change your environment.
1.Get rid of ALL cigarettes and ashtrays in your home, car, and place of work.
2.Don't let people smoke in your home.
Review your past attempts to quit. Think about what worked and what did not.
Once you quit, don't smoke—NOT EVEN A PUFF!
2. Get Support and Encouragement
Studies have shown that you have a better chance of being successful if you have help. You can get support in many ways:
Tell your family, friends, and co-workers that you are going to quit and want their support. Ask them not to smoke around you or leave cigarettes out.
Talk to your health care provider (for example, doctor, dentist, nurse, pharmacist, psychologist, or smoking counselor).
Get individual, group, or telephone counseling. The more counseling you have, the better your chances are of quitting. Programs are given at local hospitals and health centers. Call your local health department for information about programs in your area.
3. Learn New Skills and Behaviors
Try to distract yourself from urges to smoke. Talk to someone, go for a walk, or get busy with a task.
When you first try to quit, change your routine. Use a different route to work. Drink tea instead of coffee. Eat breakfast in a different place.
Do something to reduce your stress. Take a hot bath, exercise, or read a book.
Plan something enjoyable to do every day.
Drink a lot of water and other fluids.
4. Get Medication and Use It Correctly
Medications can help you stop smoking and lessen the urge to smoke.
The U.S. Food and Drug Administration (FDA) has approved five medications to help you quit smoking:
1.Bupropion SR—Available by prescription.
2.Nicotine gum—Available over-the-counter.
3.Nicotine inhaler—Available by prescription.
4.Nicotine nasal spray—Available by prescription.
5.Nicotine patch—Available by prescription and over-the-counter.
Ask your health care provider for advice and carefully read the information on the package.
All of these medications will more or less double your chances of quitting and quitting for good.
Everyone who is trying to quit may benefit from using a medication. If you are pregnant or trying to become pregnant, nursing, under age 18,
smoking fewer than 10 cigarettes per day, or have a medical condition, talk to your doctor or other health care provider before taking medications.
5. Be Prepared for Relapse or Difficult Situations
Most relapses occur within the first 3 months after quitting. Don't be discouraged if you start smoking again. Remember, most people try several times before they finally quit. Here are some difficult situations to watch for:
Alcohol. Avoid drinking alcohol. Drinking lowers your chances of success.
Other Smokers. Being around smoking can make you want to smoke.
Weight Gain. Many smokers will gain weight when they quit, usually less than 10 pounds. Eat a healthy diet and stay active. Don't let weight gain distract you from your main goal—quitting smoking. Some quit-smoking medications may help delay weight gain.
Bad Mood or Depression. There are a lot of ways to improve your mood other than smoking.
If you are having problems with any of these situations, talk to your doctor or other health care provider.
--------------------------------------------------------------------------------
Special Situations or Conditions
Studies suggest that everyone can quit smoking. Your situation or condition can give you a special reason to quit.
Pregnant women/new mothers. By quitting, you protect your baby's health and your own.
Hospitalized patients. By quitting, you reduce health problems and help healing.
Heart attack patients. By quitting, you reduce your risk of a second heart attack.
Lung, head, and neck cancer patients. By quitting, you reduce your chance of a second cancer.
Parents of children and adolescents. By quitting, you protect your children and adolescents from illnesses caused by second-hand smoke.
--------------------------------------------------------------------------------
Questions to Think About
Think about the following questions before you try to stop smoking. You may want to talk about your answers with your health care provider.
1. Why do you want to quit?
2. When you tried to quit in the past, what helped and what didn't?
3. What will be the most difficult situations for you after you quit? How will you plan to handle them?
4. Who can help you through the tough times? Your family? Friends? Health care provider?
5. What pleasures do you get from smoking? What ways can you still get pleasure if you quit?
What is Secondhand Smoke?
Secondhand smoke (SHS), sometimes referred to as environmental tobacco smoke (ETS), is a mixture of the smoke given off by the burning ends of a cigarette, pipe, cigar, bidis, and kreteks (sidestream smoke) and the smoke emitted at the mouthpiece and exhaled from the lungs of smokers (mainstream smoke).1,2
The widespread practice of smoking in buildings exposes nonsmoking occupants to combustion by-products under conditions where airborne contaminant removal is slow and uncertain. Over the past two decades, medical science has shown that nonsmokers suffer many of the diseases of active smoking when they breathe secondhand smoke.
Environmental Tobacco Smoke contains at least 250 chemicals known to be toxic or cause cancer. Unfortunately, the general public’s exposure to secondhand smoke is much higher than most people realize.
--------------------------------------------------------------------------------
Working to Reduce Secondhand Smoke Exposure
In January 2000, the U.S. Department of Health and Human Services launched Healthy People 2010, a comprehensive, nationwide health promotion and disease prevention agenda. Healthy People 2010 contains 467 objectives designed to serve as a road map for improving the health of all people in the United States during the first decade of the 21st century.
Several of these objectives relate to tobacco use and exposure to secondhand smoke. One objective is to reduce nonsmoker exposure to secondhand smoke from 65% to 45% nationwide by 2010.
