Introduction: In addition to being the most accessible medical center in the community, the pharmacy is a center for storing and providing medicines and cosmetics that are directly related to people’s health. Therefore, observing environmental health issues in the pharmacy, which is managed by the pharmacist, is considered necessary. Objective: In this study, an attempt has been made to provide the necessary ground for improving the health status of pharmacies by examining the level of knowledge, attitude and practice of pharmacists active in community pharmacies and presenting it. Method: In this study, researcher-made questionnaires were designed and after reviewing its validity by experts and its reliability by Cronbach’s alpha test, were completed by pharmacists and the results were analyzed in SPSS program. Results: Examination of the data obtained from this study showed that the pharmacists in the study have the appropriate level of knowledge and attitude, but their performance in pharmacies is different. Discussion: Observation of the results of the study shows that due to the lack of appropriate practical training and the lack of strict rules by regulatory authorities, despite the appropriate level of knowledge of pharmacists, in practice do not consider themselves very obliged to observe health principles.
