Recreational use of synthetic cannabinoid receptor agonists—so-called “Spice” products—became very popular during the last few years. Several reports on clinical symptoms and poisonings were published. Unfortunately, most of these reports do not contain any analytical data on synthetic cannabinoids in body fluids, and no or only a limited number of cases were reported concerning driving under the influence (DUI) of this kind of drugs. In this article, several cases of DUI of synthetic cannabinoids (AM-2201, JWH-018, JWH-019, JWH-122, JWH-210, JWH-307, MAM-2201 (JWH-122 5-fluoropentyl derivative), and UR-144) are presented, focusing on analytical results and signs of impairment documented by the police or the physicians who had taken the blood sample from the suspects. Consumption of synthetic cannabinoids can lead to impairment similar to typical performance deficits caused by cannabis use which are not compatible with safe driving. These deficits include centrally sedating effects and impairment of fine motor skills necessary for keeping the vehicle on track. Police as well as forensic toxicologists and other groups should become familiar with the effects of synthetic cannabinoid use, and be aware of the fact that drug users may shift to these “legal” alternatives due to their nondetectability by commonly used drug screening tests based on antibodies. Sophisticated screening procedures covering the complete range of available compounds or their metabolites have to be developed for both blood/serum and urine testing.

We present a case study on a man who suffered from diabetic ketoacidosis, probably following consumption of synthetic cannabinoids. In blood from a femoral vein AB-CHMINACA, AB-FUBINACA, AM-2201, 5F-AMB, 5F-APINACA, EAM-2201, JWH-018, JWH-122, MAM-2201, STS135 and THJ 2201 could be detected by LC-MS/MS. Diagnosis of ketoacidosis as cause of death was carried out using biochemical measurements of glucose and lactate concentrations in vitreous humour (sum formula: 463 mg/dl) and cerebrospinal fluid (sum formula: 506 mg/dl), of acetone (163 mg/l in femoral venous blood) and of HbA1c (98 mmol/mol). Death due to hyperglycaemia could have been induced by skipping of insulin doses due to his intoxicated state or by the cannabinoids which were described to be able to produce hyperglycaemia themselves.

Unter plotzlichen Todesfallen versteht man den Tod innerhalb von 24 h nach Auftreten von Krankheitssymptomen. Spezielle Fallgruppen sind Todesfalle am Arbeitsplatz, im offentlichen Gewahrsam, im Strasenverkehr, beim Sport, wahrend der Schwangerschaft, im Krankenhaus und in der arztlichen Praxis. Plotzliche Todesfalle bei kardiovaskularen Grundleiden stehen dabei im Vordergrund. Neben der klassischen Morphologie spielen heute auch molekularbiologische Techniken fur die Klarung der Todesursache eine Rolle („molekulare Autopsie“). Postmortal-biochemische Untersuchungen) sind von Bedeutung bei funktionellen Todesursachen. Der plotzliche Kindstod ist definiert als plotzlicher Tod im Sauglingsalter, der nach Uberprufung der Vorgeschichte, Untersuchung der Todesumstande und den Ergebnissen der Obduktion ungeklart bleibt. Er ist eine wichtige Differenzialdiagnose zu spurenarmen gewaltsamen Todesfallen.

Aufgrund des Erfahrungsschatzes in der Erhebung, Protokollierung und Dokumentation von Verletzungsbefunden sind Rechtsmediziner seit altersher auch mit der Untersuchung Lebender nach rechtserheblichen Korperverletzungen befasst (Beweismittelsicherung am Lebenden), damit sich entsprechend erhobene Befunde und ihre Beurteilung im weiteren Verfahrensablauf als tragfahig erweisen. Das rechtsmedizinische Untersuchungsspektrum inkl. Asservation nach Sexualdelikten ist weitgehend normiert. Bei Kindesmisshandlung steht die Abgrenzung von haufig behaupteten akzidentellen Verletzungen im Vordergrund. Selbstbeschadigungen weisen typische Verletzungscharakteristika auf. In den letzten Jahren spielt die forensische Altersdiagnostik bei Lebenden eine zunehmende Rolle. Aufgabe eines Altersgutachtens ist eine Aussage zum chronologischen Alter aufgrund des physischen Entwicklungszustandes eines Individuums, welcher als biologisches Alter bezeichnet wird.

In cases of suicide at the wheel mostly velocity is used to cause death by a single occupant vehicle crash against a fixed roadside object or collision with other vehicles. A further well known mode of death is e.g. carbon monoxide poisoning. In the recent years several cases of vehicle assisted ligature strangulation resulting even in decapitation have been reported. However, cars are also used in rare cases just as places for a suicide by hanging or ligature strangulation. Not only forensic pathologists but also police officers have to be aware of this rare type of suicide to avoid unnecessary investigations.
