Introduction: Despite the well-documented benefits of smoking cessation interventions, the implementation and success of these programs in primary care settings often encounter significant barriers. A primary care provider’s personal smoking status has been identified as a potential barrier to tobacco treatment delivery. The aim of this qualitative study is to explore the experiences and perspectives of primary care providers regarding their role in delivering smoking cessation interventions to patients based on their personal smoking status. Specifically, the study seeks to examine providers’ thoughts, emotions, and behaviors concerning their own smoking behavior and to understand their attitudes and actions when supporting patients who smoke and to explore their perspectives on the effectiveness of training programs designed to promote tobacco treatment. Materials and Methods: Semi-structured interviews were conducted with 22 primary care providers from six public primary care units in the Central Macedonia Region, Greece. Thematic analysis was used to analyze data. Results: Healthcare providers who are current smokers may face unique challenges in effectively counseling patients on smoking cessation. On the contrast, non-smoking and especially previous smoking healthcare providers were noted to exhibit greater confidence and efficacy in delivering cessation support, often serving as role models for patients aiming to quit smoking. Participating in structured cessation training programs often led healthcare professionals to reflect and reevaluate their own smoking behaviors. Conclusions: Personal smoking status of primary care providers impacts the delivery of tobacco treatment, affecting their credibility and effectiveness in providing cessation support. Educational programs positively impact attitudes and behaviors, underscoring their importance in improving both PCPs’ professional effectiveness and personal health outcomes. These findings suggest that addressing PCPs’ smoking habits and enhancing training opportunities are critical for optimizing smoking cessation services.
