Theaimof the questionnairewasto obtain information on substance abuse and socioeconomic information. Logistic regression model and Chi-square, or Fisher exact test were used for statistical analysis using SPSS; and P < 0.05 was considered statistically significant. Results: The highest frequency of one time and more than one time drug usage among students pertained to hookah 41.1 and 31.1, cigarette 17.5 and 8.1, alcohol 10.8 and 7.5, Opiates 4.1 and 0.8, hashish, bang or marijuana 1.9 and 0.7, stimulants and hallucinogens 3.4 and 0.8, and glue and lighter gas 0.8 and 0.7, respectively. Based on the results in logistic regression models, male gender (AOR:3.02), mathematical physics (AOR:1.8), hookah and alcohol experience (AOR:14.4 and 3.4) for regular smoking in Model 1; male gender(AOR:2.7), cigarette and hookah experience (AOR:3.2 and 7.6) for ever use of alcohol in Model 2; and male gender (AOR:2.5), mathematics course studding (AOR:1.6), poor educational condition (AOR:1.7), high level of father education (AOR:3.9), and tranquilizer experience (AOR:5.8) for ever use of illicit drugs in Model 3 were considered as predicting factors. For all the abovementioned, p-values were less than 0.05. Conclusions: In the present study, it was found that drug abuse is at a warning rate. The findings pointed to the need for interventional plans to improve adolescents' health with regards to substance abuse. Conducting more studies on this population is necessary to approve the observed results of the present study. © 2017, Iranian Journal of Psychiatry and Behavioral Sciences.
