This Clinical Best Practice Guideline (BPG) is to replace the RNAO (2007) BPG Integrating Smoking Cessation into Daily Nursing Practice (Second Edition). This BPG provides direction to nurses and other health-care providers to support individuals who use tobacco in all care settings. The implementation of the evidence-based recommendations provided in this BPG will enhance the health-care providers' provision of quality care to clients who use tobacco and also improve clinical outcomes.

The BPG provides evidence-based best practice recommendations in three areas:

• Practice recommendations: directed primarily to nurses and other health-care providers on the interprofessional teams who provide direct care to people in health system settings
• Education recommendations: directed to those responsible for staff and student education, such as educators, quality improvement teams, managers, administrators, and academic and professional institutions.
• System, organization, and policy recommendations: directed primarily to managers, administrators, and policy-makers who are responsible for developing policy or securing the supports required within health-care organizations that enable the implementation of best practices.

For optimal effectiveness, recommendations in these three areas should be implemented together to improve tobacco interventions and to enhance the inter-professional team's ability to partner for the purpose of improving health.
