Introduction: 'Body packer' syndrome with severe intoxication or sudden death may happen in persons who smuggle drugs in their body cavities. In case of lethal outcome when carrying cocaine, it is important, but sometimes difficult to determine whether death was due to intoxication or due to other causes. Therefore, it is necessary not only to quantify cocaine and its metabolites in biological material, but also based on their distribution in body fluids and tissues to conclude whether it is acute intoxication. We described a well-documented case of fatal poisoning in a body packer and post mortem distribution of the drug in biological samples.
Case Report: A 26-year-old man was brought to hospital with no vital signs. Resuscitation measures started at once, but with no success. Autopsy revealed 66 packets of cocaine in his digestive tract, one of which was ruptured. Hyperemia of the most of all internal organs and pulmonary and brain edema were found. High concentrations of cocaine, its metabolites benzoylecgonine and ecgonine methyl ester, as well as cocaine adulteration levamisole were proven in the post mortem blood and tissues by liquid chromatography-mass spectrometry (LC-MC) method with selective-ion monitoring.
Conclusion: The ratio of cocaine and its metabolites concentrations in the brain and blood obtained by LC-MS method can be used for forensic confirmation of acute intoxication with cocaine.

Infantile occult exposure to cocaine in domestic environments represents a complex clinical and medico-legal problem, which can be associated with abuse and neglect and with potential short- and long-term health risks for children. The authors present a retrospective study on 764 children under 14 years old who accessed the Emergency Department of IRCCS Meyer from 2016 to 2023 and were included in the GAIA (Child and Adolescent Abuse Group) protocol for suspected maltreatment and abuse, and for which a urine toxicology analysis was performed. The aim is to discuss the medico-legal implications and highlight the need for a thorough evaluation and management of such situations.

Probe Electrospray Ionization (PESI) is an atmospheric pressure ionization method that can be directly coupled with a mass spectrometer to allow ultrafast analyses without chromatographic separation and with minimal sample preparation. Using the particular case of cocaine and its metabolites in human oral fluid, the main objective of the present study was to test the feasibility of a new hybrid system combining a PESI source and a quadrupole time-of-flight (QTOF). The best results were obtained for a sample preparation with a simple dilution of 100 µL of oral fluids in an ethanol / 10 mM ammonium formate buffer (50/50) and 10 µL deposited on a dedicated sample plate and introduced into the PESI source.

Introduction: Qualitative analysis of cocaine in urine is a common practice in emergency settings. However, positive results from urine screening tests do not necessarily indicate recent exposure. In this context, plasma is considered a more appropriate option due to its shorter detection window and better correlation with symptomatology.
