A recent paper published in The American Journal of Psychiatry has found a gene that might explain the high rate of smoking cessation failure among heavy smokers.  Thousands of smokers with and without the gene were compared, revealing that individuals with the high-risk gene took two years longer to quit.  However, being condemned with the high-risk gene doesn’t make it impossible to quit.  The same study shows that this gene also makes heavy smokers three times more likely to respond to smoking cessation therapy.
