This study is an investigation of the views of medical students (N=15) and physicians (N=14), in Turkey, on conscientious objection through elaboration on their experiences in medical practice within the framework of conscientious objection, and evaluation of the data from an ethical perspective. The data received from in--depth interviews were evaluated by using the thematic content analysis method. They were then divided into contexts and themes as follows: "Refusal to provide healthcare services," "scope of conscientious objection," and "impact of conscientious objection (in case of legal entitlement)." The opinions of our research participants suggest that conscientious objection has become widespread in medical practices. It is argued that the tendency of healthcare providers and patients to find temporary resolutions to ethical dilemmas only complicates such resolutions. It is imperative, therefore, to set a rational limit on conscientious objection so as to prevent the adoption of an attitude shaped completely by the personal beliefs of the physician or the patient.
