Quit smoking, be happier

Not only does their health improve, but people who quit smoking get a boost in their quality of life, new research finds. Three years after stopping, study participants who had quit reported fewer stressors and improved mood compared to those who continued smoking. Researchers from Wisconsin School of Medicine's Center for Tobacco Research and Intervention followed the participants for three years and tested their blood to see if they had actually quit. They asked about self-regard, standard of living, relationships, friendships and other measures of quality of life.
