Religiousness is rarely studied in relation to doping behaviors in sport. In this study, we sampled 27 weightlifting/powerlifting athletes from Bosnia and Herzegovina. Using the originally developed questionnaire and by means of Spearman's correlation, we interpreted data and discussed relationships between (a) social, religious, sport, and educational factors, and (b) substance use criteria, including cigarettes, alcohol, analgesics, nutritional supplementation, and doping behaviors. In conclusion, we found (1) that religiousness can be considered as a potential protective factor against doping, but also (2) that religious subjects tend to deny and underestimate the doping behaviors in their sport. Both of these findings should be extensively studied in future investigations.
