Have you ever wondered why some people find it so much
easier to stop smoking than others? New research shows that vulnerability to
smoking addiction is shaped by our genes. A study from the Montreal
Neurological Institute and Hospital - The Neuro, McGill University shows that
people with genetically fast nicotine metabolism have a significantly greater
brain response to smoking cues than those with slow nicotine metabolism.
Previous research shows that greater reactivity to smoking cues predicts
decreased success at smoking cessation and that environmental cues promote
increased nicotine intake in animals and humans.
