The aim of this project is to develop and deliver comprehensive guidelines and implementation suggestions to support people with mental health issues (MHIs) to stop smoking. Smoking rates for people with neurotic disorders are twice that of the general population, while for psychotic disorders the rate is three times higher. Yet quit rates for this population remain low for complex reasons that go beyond life conditions to include misconceptions and a lack of knowledge and skills relating to cessation support. This evidence to action project will identify and synthesise existing evidence and generate new learning through focus groups with people with MHIs and collaborative workshops with a range of partners. Guidelines that inform stop smoking support will be circulated across the Lothians to help tailor cessation interventions so that they improve the quit rates of people with MHIs.
