A widely held belief among smokers is that the habit relieves psychological symptoms. However, a new meta-analysis of 26 prospective international studies challenges this assumption. After a median follow-up of 6-12 months, smoking cessation significantly decreased anxiety, depression, and stress while increasing psychological quality of life, compared with continued smoking. Cessation of smoking resulted in an effect similar to drug therapy for depression in the general population.
