摘要:Smoking is the leading preventable cause of morbidity and mortality and has been linked with diseases such as cancer and cardiovascular diseases. The case of a 50-year-old woman with breast cancer, who suffered a stroke the previous month and is in treatment for depression and wants to quit smoking, is analyzed. She smoked 10 cigarettes a day and had never quit smoking. She received six sessions of a cognitive-behavioral psychological intervention to quit smoking. She stopped smoking and remained abstinent through the 1-year follow-up, showing a clear physical improvement and a significant reduction of depressive symptomatology (from 24 on the Beck Depression Inventory–II [BDI-II] before treatment to 1 at the 12-month follow-up). This indicates that, in many cases, smoking cessation produces an improvement not only in physical health but also in mood.
