The prevalence of substance abuse (SA) among youth has increased in recent years. However, limited data exist about SA among medical sciences students. Therefore, this study assessed SA prevalence and contributing factors among medical sciences students. This cross-sectional study was conducted in 2019. Participants were 238 medical sciences students randomly selected from Kashan University of Medical Sciences, Kashan, Iran. The data collection instrument was the SA prevalence assessment questionnaire developed by the Mental Health Center of the Ministry of Health of Iran. Data were analyzed using the SPSS (v. 22.0) software. The most commonly abused substances were waterpipe tobacco (31.9%), cigarettes (20.2%), and alcoholic beverages (10.5%). Most participants with a history of SA had started SA before entering university. The prevalence rates of waterpipe tobacco smoking, cigarette smoking, and alcohol consumption were 9.2%, 8.8%, and 4.2% in the past month and 16.4%, 18.1%, and 7.6% in the past year, respectively. The prevalence of SA among dormitory students and students with lower grade point averages was significantly higher than among non-dormitory students and students with higher grade point averages. The onset age of SA was mainly before eighteen years, so strategies are needed to reduce SA in secondary schools. Moreover, strategies are needed to prevent and reduce SA at universities, particularly among dormitory students and students with lower grade point averages. University authorities should use effective educational and counseling programs to prevent student SA.

Internet addiction is one of the problems that has arisen with the advancement of technology, which has negative effects on people's physical and mental health. This study aimed to investigating the effect of using the internet and social networks in students of Kashan University of Medical Sciences.

In this cross-sectional study, 238 students of Kashan University of Medical Sciences were selected by stratified random method in 2019. To collect data, a standard questionnaire prepared by the professors and experts of the mental health center of the Ministry of Health was used. The data was analyzed through SPSS and using chi-square test.

The findings showed that 16.1% of students were addicted to social networks, which was 18.4% and 12.7% among women and men, respectively. Also, it can be mentioned that male students use more online and offline computer games than female students (P<0.05). The rate of use of dormitory students for searching news and surfing the web and downloading movies and music was more than students of living at home (P<0.05), also.

Considering that 16.1% of students devote at least 8 hours of their time daily to use the internet, this can be a reason for their academic failure. Hence, it is necessary to hold educational workshops about the advantages and disadvantages of internet.
