Logistic regression indicated that the factors affecting depression included type of abused drugs, income, duration of treatment, and place of residence.

Conclusions: Concerning the abovementioned points, it seems that depression is one of the common problems of substance use disorder. Considering the mental problems of substance abusers, appropriate therapies have an essential role in their treatment.
