polydrug

Combined-substance impairment: two or more drugs, or alcohol plus a drug, acting together (e.g., ethanol with benzodiazepines, cannabis with opioids), and the additive or synergistic interaction effects on driving. Defined by the COMBINATION itself, distinct from every single-substance tag — alcohol, cannabis, opioids, illicit_drugs, prescription_meds — which each address one agent in isolation.
