Studies in multiple countries have identified an association between smoking and mental health, including a recent Canadian analysis linking smoking with a number of mental health problems, such as anxiety, mood disorders and depression.iii Figure1.13 shows self-reported ratings of mental health by smoking status. While the proportion of respondents who reported “excellent” or “very good” mental health was high overall, it was significantly lower among current smokers (65%a) than former (71%b) or never (77%c) smokers.25
