METHODS The prospective study was conducted from March 21, 2009 to March 21,2010, and comprised all patients referred to the seven addiction treatment centres in Birjand. Data was obtained through pre-designed questionnaires and it was analysed using SPSS 16. RESULTS Of the 700 substance users referred to the 7 centres and who volunteered to participate, 632 (90.3%) were males and 68 (9.7%) were females. The male/female ratio was approximatly 9.3/1. Mean age was 34+/-10.2 (range: 10-75) years. The type of drugs used included traditional drugs (n= 342; 48.9%) and newer modern drugs (n=314; 44.9 %). The mean age of the first experience with drugs was 21.91+/-7.1 (range=0-60) years. There was significant different between the type of drugs used and the place of residence (p<0.019), age (p<0.0001), martial status (p<0.0001), occupation (p<0.006) and education (p<0.017). CONCLUSION The prevalence of illicit drug addiction was quite high. There seemed to have been a change in the pattern of drug use and in the type of illegal drugs used in the study area, from traditional drugs to new and modern drugs. As such, identifying risk factors related to addiction and the prevention of addiction should be one of the most important health priorities for the authorities.
