In Iran, the situation is worse, and there is one drug addict per 100 people. The research method in this study is analytical descriptive. The study population consisted of all rehabilitated addicted men and women who were spending their time in prison. Total sample size were 134 people (99 men and 35 women). A special designed questionnaire used to collect data, which included socio-demographic characteristics. The validity of the questionnaire has content validity and for reliability, Cronbach ? was used which was 0.78. The formal years of education was 4.3 year. The average age of the first drug use was 12 years for men and 22 years for women. Sixty-nine point seven percent of men used drugs with their friends and 31.4% of women used drug with their husbands. The men more than women, single men more than married women, and illiterates or poor literates were more at risk. Most men blamed bad friends and women blamed physical and psychological problems as the cause of addiction. The singles got addicted due to bad friends and married individuals were addicted due to emotional distress. The majority of age group (27-13 years), got addicted due to bad friends and older groups addicted due to emotional distress. In other words, the older the person gets, the influence of bad friends decreases, and the effect of psychological distress due to conflict and adversity increases.
