Abstract

This case report centres on the post-mortem distribution of the synthetic cannabinoid MDMB-CHMICA and its metabolites in the case of a 27-year-old man found dead after falling from the 24th floor of a high-rise building. Toxicological analysis of post-mortem samples confirmed, besides consumption of the synthetic cannabinoids MDMB-CHMICA (1.7ng/mL femoral blood) and EG-018, the abuse of THC (9.3ng/mL femoral blood), amphetamine (1050ng/mL femoral blood), MDMA (275ng/mL femoral blood), and cocaine. Regarding EG-018 and cocaine, only traces were detected in heart blood as well as in the brain (EG-018) and urine (cocaine), respectively, which is why no quantification was conducted in the femoral blood sample. It was concluded from femoral blood analysis that, at the time of death, the man was under the influence of the synthetic cannabinoid MDMB-CHMICA, THC, amphetamine and MDMA. Comprehensive screenings of all post-mortem specimens were conducted to elucidate the post-mortem distribution of MDMB-CHMICA and its metabolites. The MDMB-CHMICA concentrations ranged between 0.01ng/mL (urine) and 5.5ng/g (brain). Comparably low concentrations were detected in cardiac and femoral blood (2.1ng/mL and 1.7ng/mL, respectively) as well as in the psoas major muscle (1.2ng/g). Higher concentrations were found in the lung (2.6ng/g), liver (2.6ng/g), and kidney (3.8ng/g). Gastric content yielded a MDMB-CHMICA concentration of 2.4ng/g (1.1g absolute). Screening for MDMB-CHMICA metabolites resulted in the detection of mainly monohydroxylated metabolites in the blood, kidney, and liver specimens. Results indicated that monohydroxylated metabolites of MDMB-CHMICA are appropriate target analytes for detecting MDMB-CHMICA intake.
