The purpose of this study is to investigate the relationship between economic, social and demographic factors with the prevalence rate of drug use in the provinces of Iran during the period of 1386-1394. Due to the lack of reliable and sufficient data, a time series data for the prevalence rate is developed by using probit models and estimation of the probabilities of addiction for 10 age groups with different demographic characteristics in three groups of provinces (with high, medium, and low prevalence rates). Then, the panel data model was used to answer the research questions. The results of the first part of this study show that the prevalence rate of drug use in the Iran increased from about 3.7% in 2007 to about 4.5% in Year 2015. The results of the second part of the study show that the prevalence rate of addiction has a negative and significant relationship with per capita income; men education level, and has a positive and significant relationship with inflation and Gini coefficient. Also, the results indicate a positive and significant relationship between the prevalence rate of addiction and the poverty and unemployment (especially men unemployment). Another finding is the negative and significant relation between the prevalence of addiction and the real per capita government expenditure. Also, the positive relationship of the economic downturn with the prevalence rate is confirmed. This fact suggests that the rate of drug addiction is counter-cyclical in the country.

Expansion of foreign trade has important effects on energy intensity based on the structural conditions and economic nature of countries. In the present research the scale effect (the economy volume changing), the composite effect (the structure of economic activities changing) and the technical effect (productivity changing) resulting from the trade on the energy intensity of Iran economy, as one of the important economic-environmental indicators is investigated. For this purpose the empirical model of the research according to the economic theories by using the structural vector autoregression in 1353-1392 is modeled. The results of the model show that the trade expansion have positive scale and composite effects but negative technical effect on the energy intensity of Iran. Also the size of technical effect is bigger than the resultant of the two other effects. Therefore according to the results, increasing the volume of foreign trade has not energy intensive effect and there is evidence that energy intensity decreases from the total factors productivity channel (as an indicator of technical changes). Therefore the expansion of foreign trade in Iran is considered energy saving.
