This study aims to identify the use of social networking sites by Jordanian university students to spread health awareness about the dangers of drugs. This study followed the descriptive analytical approach, and a questionnaire was developed to match the study dimensions. The study population consisted of students from the University of Jordan, who were randomly selected (600 males and females). The study showed a significant effect of the University of Jordan students' use of social networking sites in spreading awareness about the danger of drugs. Also, there was a statistically significant difference at [alpha] = 0.05 for the Jordanian university students' use of social networking sites in spreading awareness about drug dangers. In addition, there were differences in the respondents' answers to the questionnaire due to the gender variable in favor of males. Furthermore, the results showed no differences according to the school year variable. In light of the current results, the study confirms the need to use social media to spread health awareness about the dangers of drugs, especially among students, because of the great damage to their health and society. Especially, university students are the educated group in society, and they have the role of educating others, not drug addiction.
