Once You Start, It's Hard to Stop
Smoking is 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.
People start smoking for a variety of different reasons.
Some think it looks cool. Others start because their family members or friends smoke. Statistics show that about 9 out of 10 tobacco users start before they're 18 years old. 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.
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.
Almost everyone knows that smoking causes cancer, emphysema, and heart disease; that it can shorten your life by 10 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.
The consequences of smoking may seem very far off, 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-smelling clothes and hair.
Reduced athletic performance.
Greater risk of injury and slower healing time.
Increased risk of illness.
