Smoking is the world's leading cause of cancer and death worldwide.People with mental illness may use smoking to try to alleviate symptoms, for example, using smoking to relax when they feel anxious;A cochrane review of smoking cessation treatments for people with current and historical depression found that adding psychosocial mood management to usual smoking cessation treatment (e.g., nicotine replacement therapy) increased cessation rates when compared to usual smoking treatment alone (risk ratio: 1.47; 95% CI: 1.13–1.92). In the United Kingdom, people with depression/anxiety can access psychological therapy services, known as ‘Improving Access to Psychological Therapies’ (IAPTs), in which service users receive evidence‐based therapies to improve mood and well‐being. IAPT receives over 1.5 million referrals a year,Qualitative studies embedded within randomized‐controlled trials (RCTs) provide the potential to gain new understandings of participant experiences of an intervention and inform the development of future interventions.Acceptability of the integrated smoking cessation treatment.Views of psychological well‐being practitioners' (PWPs') ability to deliver the smoking cessation treatment.Positive and negative impacts of smoking cessation treatment.
