From all of 35580 patients, 346 patients (0.97%) that 71% of them were male died and the causes of their poisoning were intentional, incorrect use, accidental, unknown and occupational in 57.5%, 35%, 5%, 2% and 0.5% of cases respectively. The most common causes of death induced by poisoning were as follows: opiate compounds (39.5%), drugs (21.7%), pesticides (17.3%), unknown (7.8%), depilatory compounds (6.6%), alcohol (3%), cyanide and carbon monoxide (2.6%), bites (0.6%), corrosive agents (0.6%) and poisonous plants (0.3%). About 16.5% of dead cases were in emergency or before reaching to the hospital.
