NEW YORK (Reuters Health) - Teens who smoke heavily may be putting themselves at increased risk of anxiety disorders, a team of researchers report.
The investigators found that teens who smoked more than one pack a day were nearly seven times as likely as those who smoked less or did not smoke to have agoraphobia--or a fear of public places and open spaces--in young adulthood.
These teens were also more than 15 times as likely to have panic disorder and nearly 6 times as likely to have generalized anxiety disorder. The findings remained despite age, gender, parental smoking, education and other factors, according to the report in the November 8th issue of The Journal of the American Medical Association (news - web sites).

Researchers interviewed nearly 700 adolescents and their mothers. The young adults were interviewed at an average age of 16 and again 6 years later at an average age of 22 years.
About 31% of 39 individuals who reported smoking at least 20 cigarettes a day in the first interview had anxiety disorders in the next interview, compared with 9% of those who were not heavy smokers.
Scientists have been investigating the link between smoking and anxiety disorders for some time, but it has not been clear whether smoking causes anxiety or anxiety makes people more likely to smoke, according to Dr. Jeffrey G. Johnson, from Columbia University in New York City and colleagues.

The current research may shed light on the issue by showing that adolescents who reported anxiety disorders in the first interview did not appear to be at higher risk of smoking in the second interview.
The findings may also help persuade adolescents to quit or not to begin smoking, the authors suggest. ``We believe that many young people may decide not to start smoking if they realize that developing a smoking habit may contribute to the development of severe anxiety disorders,'' Johnson told Reuters Health.

``This study is important because it highlights how cigarette smoking may rapidly and negatively affect a teen's emotional health--perhaps even before any of the widely known physical effects such as cancer may occur,'' Dr. Alan I. Leshner, director of the National Institute on Drug Abuse, said in a prepared statement.
As to how smoking might cause anxiety disorders, the researchers note that breathing problems have been linked by earlier research to panic disorders. The current findings suggest that by impairing breathing, smoking may raise the risk of these disorders.
