Cigarette smoking poses significant health burdens for people with mental illness. They die sooner than they should, and smoking is a major contributor to their high rates of morbid chronic physical health conditions and early mortality, compared to the general population. Family carers provide important support to people with mental illness. However, family carers' perspectives of smoking by their family members with mental illness are largely absent from the research literature and from practice, despite smoking rates remaining high and quit rates remaining low for this population.
