An Accidental Fatal Intoxication with Methoxetamine

This paper reports an unintentional death involving the administration of methoxetamine [2-(3-methoxyphenyl)-2-(ethylamino)-cyclohexanone] and offers some reference values from living drug abusers. Methoxetamine is a new recreational drug with a similar structure to ketamine. The deceased was a 26-year-old male with a history of drug abuse; he was found lying on the floor in his apartment. Several red-line plastic bags were found, one of which was labeled 2-(3-methoxyphenyl)-2-(ethylamino)-cyclohexanone and another labeled Haze. In four cases from living subjects with unknown doses, concentrations of methoxetamine were found from 0.13 to 0.49 g/g. In three of the cases, the blood samples also contained natural or synthetic cannabinoids. In the autopsy case, a considerably higher concentration of methoxetamine, 8.6 g/g, was found in femoral blood. In addition, tetrahydrocannabinol and the three different synthetic cannabinoids AM-694, AM-2201, and JWH-018, were present in femoral blood. The circumstances and the high femoral blood concentration of methoxetamine point toward an unintentional, acute fatal intoxication with methoxetamine, although the presence of the three synthetic cannabinoids may have contributed to the death.
