Substance use disorder is one of the main mental health problems in Iran. In this paper, the six-monthly counts of deaths due to substance abuse in Iran at provincial level between March 21, 2005, and March 20, 2014, were modeled using a log-Gaussian Cox point process model. By assuming population density as the exposure variable, the considered model incorporated known and unknown influential factors in order to describe spatio-temporal variations in the relative risk of substance abuse mortality. We found evidence of spatial heterogeneity and inequality by gender in deaths related to substance abuse across Iran. This study provides the first evidence in Iran on the spatio-temporal heterogeneity in mortality caused by substance use disorders.
