Abstract

Introduction: Synthetic cannabinoids are an emerging clinical and public health concern. The current study aimed to determine: (1) The characteristics and circumstances of death of all recorded cases of synthetic cannabinoid-related sudden or unnatural death in Australia, (2) The toxicology of cases and (3) Their major organ pathology.

Methods: Retrospective study of all cases in Australia in which synthetic cannabinoid use was a mechanism contributory to death (n  =  55) retrieved from the National Coronial Information System (2000–2017). Information was collected on cause of death, demographics, drug use history, circumstances of death, toxicology and major organ pathology.

Results: The mean age was 37.2 years and 91.1% were male. Causes of death comprised of accidental toxicity (38.2%), accidental toxicity/cardiovascular disease (9.1%), natural disease (20.0%), suicide (10.9%) and traumatic accident (10.9%). The most common clinical presentation proximal to death was sudden collapse (25.5%). Cardiovascular disease was prominent: severe atherosclerosis (20.0%), myocardial replacement fibrosis (18.0%), cardiomegaly (12.0%). The most frequent synthetic cannabinoids were the indazolecarboxemides (61.8%), most commonly AB-CHMINACA (38.2%). The most frequent other substances were alcohol (34.5%) and Δ9-THC (23.6%).

Conclusions: AB-CHMINACA was the most commonly seen synthetic cannabinoid. There was a high representation of relatively older decedents and of older males in particular. While acute toxicity was the most common cause of death, cardiovascular disease was prominent.
