BackgroundComprehending the toxic effects of substances co-detected in bodily fluids presents a formidable challenge. The combined toxic effect of carbon monoxide and methamphetamine remains a rarely discussed issue within the realm of scholarly literature. The main objective of this research is to delve into the potential intricacies of death mechanisms, unraveling the profound impact of both CO and methamphetamine on the heart.Case presentationThe cause and mechanism of death of a young man with toxic levels of CO–Hb and low-dose methamphetamine in his bloodstream were discussed in conjunction with the literature in this study. Methamphetamine levels of 30 ng/mL (0.03 mg/L) and 25.8% CO–Hb were detected in the blood of a 25-year-old individual who was found dead and without any disease.ConclusionsAlthough the amounts of methamphetamine and CO–Hb in the blood were not in the deadly range, it was determined that death occurred as a result of the combined action of these substances. In the present case, it was considered that death occurred as a result due to the combined cardiac effect of methamphetamine and CO, before the lethal blood CO level was reached.
