    smoking


    When
    your parents were young, people could buy cigarettes and smoke pretty
    much anywhere - even in hospitals! Ads for cigarettes were all over the
    place. Today we're more aware about how bad smoking is for our health.
    Smoking is restricted or banned in almost all public places and
    cigarette companies are no longer allowed to advertise on buses or
    trains, billboards, TV, and in many magazines.

    Almost
    everyone knows that smoking causes cancer, emphysema, and heart
    disease; that it can shorten your life by 14 years or more; and that the
    habit can cost a smoker thousands of dollars a year. So how come
    people are still lighting up? The answer, in a word, is addiction.

    Once You Start, It's Hard to Stop
    Smoking's
    a hard habit to break because tobacco contains nicotine, which is
    highly addictive. Like heroin or other addictive drugs, the body and
    mind quickly become so used to the nicotine in cigarettes that a person
    needs to have it just to feel normal.


    Almost
    no smoker begins as an adult. Statistics show that about nine out of
    10 tobacco users start before they're 18 years old. Some teens who
    smoke say they start because they think it helps them look older (it
    does - if yellow teeth and wrinkles are the look you want). Others
    smoke because they think it helps them relax (it doesn't - the heart
    actually beats faster while a person's smoking). Some light up as a way
    to feel rebellious or to set themselves apart (which works if you want
    your friends to hang out someplace else while you're puffing away).
    Some start because their friends smoke - or just because it gives them
    something to do.


    Some
    people, especially girls, start smoking because they think it may help
    keep their weight down. The illnesses that smoking can cause, like
    lung diseases or cancer, do cause weight loss - but that's not a very
    good way for people to fit into their clothes!

    Another
    reason people start smoking is because their family members do. Most
    adults who started smoking in their teens never expected to become
    addicted. That's why people say it's just so much easier to not start
    smoking at all.

    The
    cigarette ads from when your parents were young convinced many of them
    that the habit was glamorous, powerful, or exciting - even though it's
    essentially a turnoff: smelly, expensive, and unhealthy. Cigarette ads
    from the 1940s even showed doctors recommending cigarettes as a way to
    relax!

    Cigarette
    ads still show smokers as attractive and hip, sophisticated and
    elegant, or rebellious and cool. The good news is that these ads aren't
    as visible and are less effective today than they used to be: Just as
    doctors are more savvy about smoking today than they were a generation
    ago, teens are more aware of how manipulative advertising can be. The
    government has also passed laws limiting where and how tobacco
    companies are allowed to advertise to help prevent young kids from
    getting hooked on smoking.

    How Smoking Affects Your Health
    There
    are no physical reasons to start smoking - the body doesn't need
    tobacco the way it needs food, water, sleep, and exercise. In fact,
    many of the chemicals in cigarettes, like nicotine and cyanide, are
    actually poisons that can kill in high enough doses. The body's smart
    and it goes on the defense when it's being poisoned. For this reason,
    many people find it takes several tries to get started smoking:
    First-time smokers often feel pain or burning in the throat and lungs,
    and some people feel sick or even throw up the first few times they try
    tobacco.


    The
    consequences of this poisoning happen gradually. Over the long term,
    smoking leads people to develop health problems like cancer, emphysema
    (breakdown of lung tissue), organ damage, and heart disease. These
    diseases limit a person's ability to be normally active - and can be
    fatal. Each time a smoker lights up, that single cigarette takes about 5
    to 20 minutes off the person's life.


    Smokers
    not only develop wrinkles and yellow teeth, they also lose bone
    density, which increases their risk of osteoporosis (pronounced:
    ahs-tee-o-puh-row-sus, a condition that causes older people to become
    bent over and their bones to break more easily). Smokers also tend to
    be less active than nonsmokers because smoking affects lung power.
    Smoking can also cause fertility problems in both men and women and can
    impact sexual health in males.

    The
    consequences of smoking may seem very far off to many teens, but
    long-term health problems aren't the only hazard of smoking. Nicotine
    and the other toxins in cigarettes, cigars, and pipes can affect a
    person's body quickly, which means that teen smokers experience many of
    these problems:


    Bad skin. Because smoking restricts blood vessels, it can prevent
    oxygen and nutrients from getting to the skin - which is why smokers
    often appear pale and unhealthy. An Italian study also linked smoking
    to an increased risk of getting a type of skin rash called psoriasis.

    • Bad breath. All those cigarettes leave smokers with a condition called halitosis, or persistent bad breath.

    Bad-smelling clothes and hair. The smell of stale smoke tends to
    linger - not just on people's clothing, but on their hair, furniture,
    and cars. And it's often hard to get the smell of smoke out.


    Reduced athletic performance. People who smoke usually can't compete
    with nonsmoking peers because the physical effects of smoking - like
    rapid heartbeat, decreased circulation, and shortness of breath -
    impair sports performance.


    Greater risk of injury and slower healing time. Smoking affects the
    body's ability to produce collagen, so common sports injuries, such as
    damage to tendons and ligaments, will heal more slowly in smokers than
    nonsmokers.


    Increased risk of illness. Studies show that smokers get more colds,
    flu, bronchitis, and pneumonia than nonsmokers. And people with certain
    health conditions, like asthma, become more sick if they smoke (and
    often if they're just around people who smoke). Because teens who smoke
    as a way to manage weight often light up instead of eating, their
    bodies lack the nutrients they need to grow, develop, and fight off
    illness properly.

    Smoking Is Expensive
    Not
    only does smoking damage health, it costs an arm and a leg. Depending
    on where you live, smoking a pack of cigarettes a day can cost about
    $1,800 dollars a year. That adds up. It's money you could save or spend
    on something for yourself.

    Kicking Butt and Staying Smoke Free
    All
    forms of tobacco - cigarettes, pipes, cigars, and smokeless tobacco -
    are hazardous. It doesn't help to substitute products that seem like
    they're better for you than regular cigarettes - such as filter or
    low-tar cigarettes.

    The
    only thing that really helps a person avoid the problems associated
    with smoking is staying smoke free. This isn't always easy, especially
    if everyone around you is smoking and offering you cigarettes. It may
    help to have your reasons for not smoking ready for times you may feel
    the pressure, such as "I just don't like it" or "I want to stay in
    shape for soccer" (or football, basketball, or other sport).

    The
    good news for people who don't smoke or who want to quit is that
    studies show that the number of teens who smoke is dropping
    dramatically. Today, only about 22% of high school students smoke, down
    from 36% just 7 years ago.

    If
    you do smoke and want to quit, there's more information and support
    out there than ever. Different approaches work for different people -
    for some, quitting cold turkey is best, whereas others find that a
    slower approach is the way to go. Some people find that it helps to go
    to a support group especially for teens; these are sometimes sponsored
    by local hospitals or organizations like the American Cancer Society.
    And the Internet offers a number of good resources. Check out some of
    these by clicking on the Resources tab to the right of this article.
    When quitting, it can be helpful to realize that the first few days are
    the hardest, and it's normal to have a few relapses before you manage
    to quit for good.

    Staying
    smoke free will give you a whole lot more of everything - more energy,
    better performance, better looks, more money in your pocket, and, in
    the long run, more life to live
