The aim of the Clean Air For All Project was to establish procedures to assess and treat nicotine dependence in patients admitted to mental health units in the Sydney South West Area Health Service. The results of the project demonstrated that, with the support of staff in mental health units, patients who smoke can successfully use nicotine replacement therapy to deal with their nicotine dependence while an inpatient. The project was funded under the NSW Health Promotion Demonstration Research Grants Scheme.
