title: Drug Abuse among University Students of Rafsanjan, Iran.
abstract: OBJECTIVE
  The present study aimed to determine the frequency of drug abused in a sample of university students in Rafsanjan, Iran.
  
  
  METHODS
  In this cross-sectional study, 1,260 students volunteered (311 males and 949 females) with mean age of 21.35 years. Data were collected by a self-administrated questionnaire regarding drugs abuse and demographic information.
  
  
  RESULTS
  Benzodiazepines were the most common abused drugs which were reported in 94 students (7.4%). Other agents studied were cigarette and tobacco (159, cases 12.6%), alcoholic drinks (60 cases, 4.7%), and opiates (42 cases, 3.3%). Forty-three students (3.4%) had used methylphenidate in the last 6 months. Of this, 39 (90.6%) experienced insomnia. All students who abused methylphenidate indicated that the reason for this behavior was to raise alertness and conscious levels.
  
  
  CONCLUSIONS
  The pattern of drug abuse among the students here seems similar to other reports from Iranian universities.
