Individuals with mental disorders exhibit a notably heightened dependence on tobacco, approximately twice as high as that of the general population. The long-term effects of nicotine consumption include an exacerbation of depressive symptoms and a decline in mental health, which can be considered additional risk factors for the vulnerable population of smokers with preexisting mental disorders. Successful smoking cessation is associated with an increase in mental health, comparable or superior to that of pharmacological antidepressant treatments. However, smoking is frequently disregarded within the realm of psychotherapeutic care, unlike in the treatment of other substance use disorders. Smoking may hinder patients' recovery and responsiveness to psychotherapy, potentially distorting improvements in symptom severity or negative affect. Integrating smoking cessation initiatives into standard psychotherapeutic interventions thus holds significant potential and may be considered essential for long-term mental health. The current study's objective is to assess the potential of a guideline-based smoking cessation intervention within an outpatient psychotherapeutic setting concerning changes in smoking intensity, nicotine dependence, and mental health outcomes among patients with a mental disorder adjunct to concurrent psychotherapy. This trial aims to bridge the gap between the state of research in light of evidence of the positive effects of successful smoking cessation and the actual practical provision of care in Germany.en150 PsychologieAdjuvant treatment optionsCognitive behavioral therapyNicotine dependenceShort-term treatmentSmoking cessationSubstance use disordersRauchentwöhnungNikotinabhängigkeitArticlehttps://doi.org/10.1186/s13063-025-08781-2urn:nbn:de:hbz:467-29136
