WASHINGTON People with hostile or aggressive personality traits may have genetic tendencies that make them "born to smoke," researchers reported yesterday.
Brain-imaging studies suggest that the same genetic variations that give people hostile personality traits may also make them more likely to become addicted to nicotine, the team at the University of California Irvine reported.
"We call this brain response a 'born to smoke' pattern," said Dr. Steven Potkin, a professor of psychiatry and a brain-imaging specialist.
Potkin's team was following up on evidence suggesting that people with hostile personality traits are more likely to become addicted to cigarettes and have trouble kicking the habit. Reuters
