Smoking gun: cigarettes are addictive and deadly. So why are teens still smoking? (Close Up: Nicotine).

If you're looking for the Robinson

Rams baseball team during fourth period lunch, don't bother searching the cafeteria or the practice diamond. On most afternoons, you'll find a handful of the top players from Robinson Secondary School in Fairfax, VA, huddled in a friend's nearby basement. They eat pizza. They play Tony Hawk video games. And always--always--they smoke cigarettes.

"Kids hanging out. Whether it's a party or lunch, there are going to be smokes," says Kevin McNamara, an 18-year-old Robinson senior and a regular attendee at the basement brunch. Kevin is a star member of the school's golf team. He was also the Rams' ace pitcher until he tore a ligament in his knee.

And, until recently, he smoked two packs a day.

"Kevin's story is not unusual," says Dr. Bill Corrigall, Director of NIDA's Nicotine and Tobacco Addiction Program. "Many teens and even pre-teens begin to experiment with smoking, but soon find they are smoking regularly--they're addicted."

"I WANT TO QUIT"

"I used to be able to run a mile in under six minutes. Now I'm lucky to make it in eight. And I'm wheezing all the way," says Kevin, who's cut his daily use down to ten cigarettes. "I want to quit. But it's not that easy."

More than ever, teens find that the best way to stop smoking is to never start at all. Teen smoking rates have steadily fallen since 1996, according to a NIDA-funded study.

That's the good news. The bad news, experts say, is that teen smoking numbers are still too high. Each day, more than 3,000 children and adolescents become cigarette smokers, notes the Centers for Disease Control and Prevention. That's more than 1 million teens a year. Roughly one-third of them will die from a smoking-related illness.

"There's hard evidence that smoking leads to addiction, health problems, and death," says Dr. Eric Moolchan, director of NIDA's Teen Tobacco Addiction Treatment Research Clinic. "Teens have a choice: They can become victims, or they can stop before they go too far. Better yet, they never have to start at all."

"I MUST HAVE BEEN CRAZY"

Even those who are well aware that smoking kills find cigarettes hard to resist. Sarah Millermon, an 18-year-old from Stockton, CA, knows the dangers of cancer first-hand.

When she was a baby, she developed leukemia, a blood-related cancer. She underwent chemotherapy until she was two. And, while she's been cancer-free ever since, the prospect of a relapse is never far from her mind.

Still, as a teen, Sarah went on to smoke a pack a day, putting herself at risk for cancer of the lungs, mouth, esophagus, larynx, stomach, pancreas, kidney, and bladder.

"When you're addicted to cigarettes, you can rationalize anything," says Sarah, who hasn't smoked in three months. "I'd tell myself: `Well, I beat cancer once. I can do it again.' Now I look back and think I must have been crazy."

"I HORRIBLE THING TO SEE"

Unlike Sarah, some teens see the ravaging effects of cancer and vow never to pick up a cigarette. Ashley Sobrinski, a 14-year-old from Ocean City, NJ, watched her grandfather succumb to lung cancer.

"It's a horrible thing to see," she says. "The cancer just took over his body." He began smoking as a teenager in the Navy. Ashley understands how a teen in the 1940s might have been tricked into taking up cigarettes. But she can't see how today's teens fall for it.

"With all the information that's out there, with all the people who have died from smoking, it just puzzles me that kids keep doing it" she says. "You know that if you put that cigarette in your mouth, it might kill you. But you do it anyway. That just doesn't make sense."

CIGARETTES: HOW THEY LOOK AND HURT

Cigarette smoke contains more than 4,000 chemicals, including toxins like ammonia. But the chief culprit in cigarettes is nicotine, a powerfully addictive drug.

With every puff of a cigarette, nicotine alters how your brain functions. Like cocaine and herein, nicotine stimulates the release of a molecule called dopamine, located in parts of the brain that are involved in addictive behaviors. Although a user does not get the high from cigarettes that one might get from drugs like cocaine and heroin, make no mistake: nicotine affects your brain.

Nicotine "primes" the brain for addiction. You can begin to crave cigarettes more than anything else. "Smoking becomes your sole focus," says Dr. Cindy Miner, the Chief of NIDA's Science Policy Branch. "Nothing else is as pleasurable as it used to be."

Indeed, your brain becomes so used to the presence of nicotine that, when you try to quit, it rebels and craves more.

But addiction may be just the tip of the iceberg when it comes to risks from smoking. When you inhale, cigarette smoke and the chemicals it carries are absorbed by the lungs and quickly move into the bloodstream, where they circulate through your heart to your brain and the Pest of your body. Your lungs fill with chemical deposits.

"You're taking tar into your lungs and there's no way to clear out all that debris," says Miner. "Suddenly you find that you are gasping for breath on the soccer field."

Research suggests that nicotine is even more harmful to the developing heart, lungs, and brains of teens. "The younger you start, the more likely you will get hooked," Miner says. "The younger you get hooked, the more cigarettes you will smoke. And the more cigarettes you smoke.... Well, we know where that leads."

By Any Other Name

As if cigarettes aren't bad enough, there are other hazardous tobacco products, Because of they look or smell or how they're used, some people might think they're not as addictive or harmful as cigarettes. But here's the truth:

* Chewing tobacco: Spit, snuff, dip, smokeless. The amount of nicotine in one pinch of dip can be five times as high as in a cigarette. Plus, dip comes with its own health risks. From the toxins in the juice created, chewers can develop painful lesions on their tongue, as well as cancer of the esophagus, pharynx, larynx, and stomach. Perhaps worst of all are cancers of the mouth and tongue, which often require surgery to remove parts of a user's face. These cancers from chewing tobacco often occur earlier rather than later, in a user's life.

* Cigars: Cigars are puffed and not inhaled, but the smoke still gets into the lungs and does just as much damage as cigarettes, and cigar smokers risk the same oral cancer and other irritation problems as people who chew tobacco. Also, a cigar delivers nicotine. In fact, it delivers about four times as much nicotine as a cigarette.

* Bidis: These hand-relied cigarettes from India (pronounced "beedees") are often packaged in cinnamon, orange, and chocolate flavors to appeal to kids. But don't let the taste fool you. Bidis are generally unfiltered and can have 28 percent higher nicotine concentration levels than cigarettes.
