Smoking rates have been falling substantially over the last 50 years, particularly in high income countries, with the rate of tobacco use now at 19.7% in the U.S in 2018. In contrast, this rate remains stubbornly high (36.7%) in people with mental health issues.
Some people believe smoking offers mental health benefits, such as reducing stress and anxiety. In one study, it was not just smokers who thought this but also mental health practitioners. Around 40–45% of mental health professionals assumed that smoking cessation would not be helpful to their patients.
