Our study showed a gradually increasing numbers of adverse drug cases in forensic identification year by year with a slight female predominance (20/33 cases, 60.6%). Of the 33 victims, nearly two-thirds (21/33, 63.6%) were due to hospital errors including only one case of drug overdose (1/21, 4.8%), whereas the rest were not related to the hospital errors. Eight cases (8/33, 24.2%) were caused by illegal medical practitioners due to improper use of medication.
