INTRODUCTION: With increased use, the number of cocaine-related deaths has increased. We aimed to determine: (i) the toxicological profile of cocaine, metabolites and adulterants amongst three groups of cocaine-related fatalities in which cocaine and/or metabolites were present in blood: (a) fatal toxicity, where cocaine only (CO) was present (n = 48), (b) multiple drug toxicity (MDT) where other drugs were present (n = 604), and (c) a comparison group of death from traumatic injury (TI, n = 232); (ii) the acute clinical presentation by group; and (iii) cardiovascular disease by group.
METHODS: Retrospective study of cocaine-related deaths in Australia, 2000-2021, from the National Coronial Information System.
RESULTS: The parent drug cocaine was significantly more common, and had a higher median concentration, amongst the CO group (97.9%, 1.550 mg/L) than the MDT (68.9%, 0.09 mg/L) and TI (70.7%, 0.05 mg/L) groups respectively. Similarly large ratios between CO, MDT and TI were seen for benzoylecgonine (2.100, 0.510, 0.240 mg/L), methylecgonine (1.350, 0.140, 0.070 mg/L), lignocaine (1.200, 0.200, 0.150 mg/L) and levamisole (0.230, 0.045, 0.025 mg/L). The two toxicity groups had significantly higher proportions than the TI group for reports of sudden collapse, seizure, acute psychosis, hyperthermia and vomiting. In addition, CO had higher proportions than MDT and TI of sudden collapse. CO had significantly higher proportions of cardiomegaly and coronary artery disease than the TI group.
DISCUSSION AND CONCLUSIONS: Compared to MDT and TI cases, CO cases had higher cocaine concentrations, higher concentrations of adulterants, higher levels of cardiovascular disease and were more likely to suddenly collapse.
