Research has shown individuals with a mental illness are about twice as likely to smoke as others who do not suffer from mental health issues 3. Evidence also suggests that together with a higher prevalence of smoking among people with a mental illness such individuals additionally smoke a higher number of cigarettes 4.
It is very difficult to establish a causal relationship between smoking and mental health because many people begin smoking before they are diagnosed with a mental health illness. It has so far not been possible to determine whether smoking increases the risk of developing a mental disorder or having a mental disorder increases the risk of smoking. People with mental health disorders may view smoking as a coping mechanism for some of the side effects of their mental illness.
Promoting smoking cessation has historically not been seen as a priority by mental health workers, despite the potential consequences of smoking for a patient’s physical health. A ‘smoking culture’ therefore developed around many mental health settings, with smoking not being challenged by staff for a wide variety of reasons. Nevertheless, we know that smokers with mental disorders are just as likely to want to quit as those without.
