Study: Teen Smoking Stunts Lung Growth

Smoking even a few cigarettes a day appears to stunt the growth of teenagers’ lungs, a Harvard University study has found.

Previous research has shown that youngsters who smoke are more likely to have coughs, asthma and bronchitis.

Now, experts have found that teenage smoking actually seems to make boys’ and girls’ lungs grow more slowly than usual, so they hold less air.

The results were published in today’s issue of the New England Journal of Medicine.
