For the purpose of measuring the degree of depression among drug addicts in Iran, the Beck Depression Inventory was administered to 50 addicts, 46 depressed non-addicts, and 48 normal controls. Statistical comparison of the BDI for the three groups yielded a significant difference between the addicts and the controls, whereas the difference between the addicts and the depressed non-addicts was not significant; this indicates that depression is one of the clinical symptoms of drug addiction in Iran.
