Smoking is the leading preventable cause of death in the Netherlands. People with a low socioeconomic position (SEP) often make much less use of policies and measures to quit smoking. They have more difficulty quitting smoking and experience greater health consequences from smoking. For example, they are more likely to suffer from a chronic disease such as COPD as a result of smoking. People are caught in a vicious cycle of chronic problems, chronic stress, and unhealthy behavior/addictions, and find it difficult to break free. Additionally, anti-smoking campaigns and smoking cessation assistance for this group often have less success. A more person-centered approach was needed: a self-help group for quitting smoking established in co-creation with the participants of this group and local healthcare professionals.
