The findings indicate that while single-substance use of alcohol or cannabis had limited impact on hemoglobin and lipid profiles, dual use was associated with elevated hemoglobin and marked liver enzyme abnormalities. Elevated AST, GGT, and bilirubin in substance users, particularly dual users, suggest potential hepatic stress, warranting targeted public health interventions and monitoring. It is recommended that routine liver function screening be incorporated into healthcare services for individuals with a history of alcohol and cannabis use to enable early detection and management of hepatic impairment.
