ScienceDaily (Oct. 23, 2008) — Young people with ADHD are not only at increased risk of starting to smoke cigarettes, they also tend to become more seriously addicted to tobacco and more vulnerable to environmental factors such as having friends or parents who smoke, according to a study from Massachusetts General Hospital reseachers.

The report in the Journal of Pediatrics also found that individuals with more ADHD-related symptoms, even those who don't have the full syndrome, are at greater risk of becoming dependent on nicotine than those with fewer symptoms.

"Knowing that ADHD increases the risk of more serious nicotine addiction stresses the importance of prevention efforts aimed at adolescents and their families," says Timothy Wilens, MD, director of the Substance Abuse Program in the MGH Pediatric Psychopharmacology Department, who led the study. "It also gives us clues about how the neurotransmitter systems involved in ADHD and tobacco use may be interacting."
