Life-threatening intoxications related to persistent MDMA (3,4-methylenedioxymethamphetamine) concentrations

As shown in these two cases, plasma MDMA concentrations measured 3/5 days after the substance's consumption were particularly high suggesting whether a consumption of a large amount and/or a saturation of the hepatic/renal elimination mechanism. Therefore, since MDMA excretion from plasma can be delayed, complete toxicology screening including the measurement of MDMA concentrations should be considered in the presence of any suspicion of MDMA intoxication.
