RESUMO
OBJECTIVES: This study aimed to provide epidemiological information on drug-facilitated sexual assault in Spanish youth partying, with a focus on prevalence rates and associated sociodemographic factors. STUDY DESIGN: Cross-sectional study. METHODS: Quota sampling was used to recruit 1601 young people aged 18-35 years in Spain from a digital panel. A validated questionnaire on drug-facilitated sexual assault was used to assess five types of lifetime victimisation experiences while partying. Chi-square and the exact Fisher tests were used to describe the prevalence of victimisation, drug use patterns, and perpetrator profiles. Generalised ordered logistic regression was used to explore factors associated with victimisation, analysed by gender. RESULTS: Half of young women and one-quarter of young men had experienced drug-facilitated sexual assault in their lifetime. Female victimisation due to touching and kissing was notably high, whereas men comprised almost half of the victims of more invasive DFSA experiences involving masturbation, penetration, and oral sex. Opportunism prevailed as the assault tactic, consisting of taking advantage of the victims' incapacity derived from voluntary alcohol use. Among women, risk of victimisation was associated with a lower education level, foreign-born status, and being non-heterosexual. Male victimisation risk was highest among non-heterosexual men. CONCLUSIONS: Drug-facilitated sexual violence in youth nightlife contexts is a serious public health issue in Spain, which requires urgent action. Most assaults involve taking advantage of victims who are incapacitated by the effects of voluntary alcohol consumption. This sexual violence primarily affects women with lower educational levels or those who are foreign-born and non-heterosexual men and women.

INTRODUCTION: Proactive drug facilitated crime (DFC) is the administration of psychoactive substances (PAS) for criminal purposes without the victim's knowledge or by force. In Paris, France, patients who report suspected proactive DFC to the police are examined at the Department of Forensic Medicine (DFM) of the Hôtel-Dieu Hospital. Preventively blood and urine samples are collected but not systematically analyzed by the judicial authority. We aimed to assess the proportion of probable proactive DFC in patients examined at the Hôtel-Dieu DFM following a police report for suspected proactive DFC. METHOD: Blood and urine samples were collected from 100 patients. Toxicological analyses were performed by the toxicology laboratory of the Lariboisière Hospital. The results were correlated with the clinical data collected at the initial and follow-up consultations. RESULTS: At least one PAS was detected in 86% of the cases (voluntary or involuntary intake). After correlation with clinical data, 32% of the cases were classified as probable proactive DFC. In these cases, 49% of the substances identified were illicit substances (amphetamines, MDMA, etc.); 16% were benzodiazepines and related substances; 16% were antihistamines and sedatives; 14% were opioids; and 5% were antidepressants and anti-epileptics. In 90% of the cases, patients reported a voluntary ethanol consumption in the hours prior to the suspected proactive DFC. CONCLUSION: Toxicological analyses revealed a high proportion of both probable proactive DFC and probable opportunistic DFC. Our results indicate the need to perform systematical toxicological analysis in cases of suspected DFC.

Criminal practices in which an individual becomes vulnerable and prone to sexual assault after ingesting drinks spiked with doping substances have become a social concern globally. As forensic protocols require a multi-tiered strategy for chemical evidentiary analysis, the backlog of evidence has become a significant problem in the community. Herein, a fast, sensible, and complementary dual analytical methodology was developed using a single commercial paper substrate for surface-enhanced Raman spectroscopy (SERS) and paper spray mass spectrometry (PS-MS) analysis to identify psychotropic substances added to alcoholic beverages irrefutably. To study and investigate this criminal practice, pharmaceutical formulations containing distinct psychotropic substances (zolpidem, clonazepam, diazepam, and ketamine) were added to drinks typically consumed at parties and festivals (Pilsen beer, açaí Catuaba®, gin tonic, and vodka mixed with Coca-Cola Zero®). A simple liquid-liquid extraction with a low-temperature partitioning (LLE-LTP) procedure was applied to the drinks and effectively minimized matrix effects. As a preliminary analysis, SERS spectra combined with Hierarchical Clustering Analysis (HCA) provided sufficient information to investigate the samples further. The presence of the protonated species for the psychotropic substances in the spiked drinks was readily verified in the mass spectra and confirmed by tandem mass spectrometry. Finally, the results demonstrate the potential of this methodology to be easily implemented into the routine of forensic laboratories and to be further employed at harm reduction tends at parties and festivals to detect contaminated beverages promptly and irrefutably as an efficient tool to prevent such crimes.

Introducción: el empleo de drogas psicoactivas para facilitar una agresión sexual ha adquirido gran relevancia en estos últimos años. El objetivo del presente trabajo es ayudar a visibilizar este tipo de situaciones, estableciendo los criterios diagnósticos y así poder determinar la incidencia real de este tipo de delitos. Material y métodos: se ha realizado un estudio descriptivo retrospectivo de las víctimas de violencia sexual mediante el empleo de sustancias psicoactivas, atendidas por los médicos forenses del Instituto de Medicina Legal y Ciencias Forenses de Alicante, en los años 2016 a 2020. Resultados: de los 702 casos estudiados de víctimas de violencia sexual, en 95 casos (13,5%) se cumplían los criterios de sospecha de sumisión química o delitos facilitados por sustancias psicoactivas. El perfil de la víctima es mujer (94,7%), de edad media 24,7 años. En la mayoría de los casos la violencia sexual fue cometida por un único agresor (80,6%), varón, conocido o recién conocido por la víctima y generalmente los hechos ocurrieron en fin de semana (54,8%). La víctima había consumido voluntariamente alcohol solo, o en combinación con drogas y/o medicamentos, inmediatamente antes de los hechos en la mayoría de los casos (88,5%). La situación de vulnerabilidad que genera este consumo puede ser aprovechado por el agresor para agredirla sexualmente (sumisión química oportunista). Los análisis químico-toxicológicos de las muestras analizadas en la sangre y la orina fueron positivos en un 85,3% de los casos. En casi la mitad de los casos fueron positivos a más de una sustancia (46,3%). Las más frecuentes encontradas fueron: alcohol (54,7%), cannabinoides (37,9%), benzodiacepinas (22,1%), cocaína (15,8%) y éxtasis (8,4%). En la mitad de los casos (50,5%), se obtuvieron hallazgos toxicológicos positivos inesperados de sustancias psicoactivas, que la víctima no admitía haber consumido voluntariamente.(AU)
Introduction: The use of psychoactive drugs to facilitate sexual assault has acquired great relevance in recent years. The objective of this work is to help make this type of situation visible, establishing diagnostic criteria and thus being able to determine the real incidence of this type of crime. Materials and methods: In order to determine the frequency and characteristics of victims of sexual assault with suspected chemical submission (SSQ), a retrospective descriptive study of sexual assaults facilitated by psychoactive substances has been carried out at the Institute of Legal Medicine and Forensic Sciences of Alicante in the years 2016-2020. Results: Among 702 cases studied, 95 (13.5%) met the criteria for inclusion in the probable DFSA (drug-facilitated sexual assault) group. The profile of the victim was a woman (95.4%) around 24 years old. In most cases, the sexual violence was committed by a single male aggressor, recently met or known by the victim, and generally these events happen on weekends. The victim had voluntarily consumed alcohol, drugs or psychotropic drugs immediately before the events in most cases (88,5%). This vulnerable state of the victim was used by the aggressor to sexually assault her (opportunistic DFSA). The toxicological analyses performed on blood and/or urine were positive in 85.3%. In almost half of them (46.3%), there was more than one substance found in the toxicological analyses. The most frequent substance found were: alcohol (54.7%), cannabinoids (37,9%), benzodiazepines (22.1%), cocaine (15.8%) and ecstasy or MDMA (8.4%). In half of the cases (50.5%), unexpected positive toxicological findings were obtained for psychoactive substances that the victim did not admit to having consumed voluntarily.(AU)

Antecedentes y objetivos: la escopolamina se emplea de forma subrepticia para cometer actos ilícitos. El número de casos de sospecha de consumo de esta sustancia en los servicios sanitarios de urgencias parece haber aumentado en los últimos años. No existe una clara y rigurosa relación con el número de casos descritos en la literatura científica, debido a la dificultad que supone su detección en los sujetos que se encuentran bajo sus efectos. Se plantea la profundización sobre la sumisión química, al describirse un caso clínico registrado en el Servicio de Urgencias del Hospital Central de la Defensa Gómez Ulla y una mejora del abordaje de este tipo de casos desde el triaje. Material y método: el estudio del caso registrado se ha basado en la descripción del método de detección analítico de la escopolamina y se ha apoyado en una revisión bibliográfica empleando distintas bases especializadas en referencia a intoxicación por escopolamina y su empleo en actos delictivos. Resultados: se identificó escopolamina. Al ser una sustancia cuya detección es tiempo-dependiente, el Hospital Central de la Defensa Gómez Ulla estableció un protocolo junto con el Instituto de Toxicología de la Defensa en 2018, a fin de realizar analíticas de identificación de sustancias empleadas en los casos de sospecha de sumisión química. Conclusiones: se plantea la necesidad de establecer protocolos de tipo multidisciplinar adecuados en los servicios de urgencias, estableciendo un diagnóstico diferencial en casos con alteraciones en el nivel de consciencia, al existir la posibilidad de intoxicación por escopolamina y sospecha de sumisión química, ya que la detección de la sustancia es tiempo-dependiente.

Antecedents and objectives: Scopolamine is used to commit illegal acts. The number of suspected cases of this substance in the Emergency Services seems to have increased in recent years. There is no clear and rigorous relationship with the number of cases described in the scientific literature, due to the difficulty of its detection in subjects who are under its effects. A further study on Chemical Submission is proposed, by describing a clinical case registered in the Emergency Service of the Gómez Ulla Central Defense Hospital and an improvement in the approach to this type of cases from triage. Material and methods: The study of the registered case has been based on the description of the analytical method and supported by a bibliographic review using different specialized bases in reference to Escopolamine poisoning and its use in criminal acts. Results: Being a substance whose detection is time-dependent, the Gómez Ulla Central Defense Hospital established a protocol together with the Defense Toxicology Institute in 2018 in order to carry out identification analyzes of substances used in cases of Suspected Submission Chemistry. Conclusions: The need to establish appropriate multidisciplinary protocols in the Emergency Services arises. Propose a differential diagnosis in cases with alterations in the level of consciousness, as there is the possibility of scopolamine intoxication and suspicion of Chemical Submission, since the detection of the substance is time-dependent.

In recent years, a significant number of investigations have discovered up to 200 000 unsubmitted sexual assault kits (SAKs) in the US. While the public outcry was largely directed towards DNA analysis, the SAKs also contained biological specimens specifically designated for toxicological analysis. Due to the sensitivity of analytes in potential drug facilitated sexual assaults, the preservation and maintenance of the specimens is crucial in providing accurate toxicological measurements. The investigations into the unsubmitted SAKs have identified subjective law enforcement officer (LEO) rationale for the unsubmitted kits, however the impact on toxicological specimens has not been examined. This brief review of policies and guidelines with respect to forensic specimens has identified potential sources of evidentiary degradation, despite the use of chemical preservatives. With respect to temperature-controlled environments, the variation in SAK submission policies established throughout the US are potentially detrimental to the preservation of toxicological evidence. Degradation as a result of time-delayed collection and poorly maintained storage temperatures plays a crucial role for/in the interpretation of qualitative and quantitative toxicological results. This review finds these delays can be addressed through modernisation of facilities; electronic tracking of unsubmitted SAKs; mandated transfer of biological evidence within 72 h; and documentation of temperature within the chain of custody or other records. Without identifying the range of temperatures in which the evidence was exposed, forensic toxicologists may unintentionally provide erroneous interpretations of toxicological analyses - potentially casting doubt on the survivor's recall of events and negatively impacting future sexual assault investigations.
RESUMO
An infrared spectroscopy (IR) based methodology has been developed to determine γ-butyrolactone (GBL) in adulterated beverages. The proposed method permits the direct screening of GBL in beverages and involves a minimum sample treatment requiring less than 2 min for quantitative determination of GBL. Sensitivity of IR method was improved by using liquid-liquid extraction (LLE) providing detection limits of 0.023 mg g-1. Accuracy of the proposed methodology was evaluated through the analysis of soft beverages and alcoholic cocktails spiked with GBL at concentration levels ranging from 0.075 to 10 mg g-1 providing recovery values from 91 to 100%. GBL was determined in twelve blind-spiked beverages, including from mineral water to wine and cocktails. Results obtained were statistically comparable to those provided by a liquid chromatography (LC) reference methodology and consistent with the spiked values. Therefore, the use of LLE-FTIR allowed a simple, sensitive and quantitative determination of GBL in soft beverages and alcoholic cocktails, thus evidencing its use for sex submission intention.

Drug-facilitated sexual assault (DFSA) and drug-facilitated crime (DFC) constitute a mode of violence that is generally unknown to the population and may go unnoticed by health professionals. The aim of this systematic review was to analyze the victims of DFC, compiling their sociodemographic characteristics, the toxic substances used and their biological matrices and modes of action, in order to identify the substances that are commonly put to criminal use. The aim would be to establish political and health strategies that inform and warn people about possible criminal social behaviors consequent danger to health. This systematic review was conducted following the PRISMA guidelines. Alcohol, benzodiazepines and cocaine were among the most commonly detected substances. In most of the hospitals, immunoassays, liquid chromatography (LC-MS), or gas chromatography-mass spectrometry (GC-MS) analyses were used to identify the substances, while the most frequently used biological matrices were blood and urine. From a judicial point of view, the instrumental protocols and techniques followed for the detection of toxics in different biological matrices must guarantee the reliability and validity of the results for use in a court of law. The recommendations of international organizations should be followed and must be called upon to strengthen their respective national laws against this chemical submission (CS) phenomenon.

Chemical Submission (CS) is considered a danger to health and a form of violence. There are different forms of proactive CS (involuntary consumption of psychoactive substances) and opportunistic CS (voluntary consumption), with criminal intent, usually theft, submission, or sexual assault. The objective of this work is to describe the characteristics of cases of suspected CS in adults older than 65 years treated in the Emergency Department of the San Carlos Clinical Hospital and the results of the toxicological analysis performed by the INTCF in Madrid (April 1, 2015-2019). There were 12 (8%) cases of suspected CS, with a mean age of 75 (SD 8) years, of which 8 (66.7%) men, with two different profiles, all associated with theft, and in 3 (25%) possible sexual assault. In 9 (75%) cases, benzodiazepines and / or usual drugs were identified. CS is a problem to consider in Emergency Departments and is not exclusive to the young population.

In order to better understand risk factors associated with drug-facilitated sexual assault (DFSA), this study examined complainant-specific and contextual factors, as well as the toxicological profile of DFSA in Victoria, Australia. Clinical files and toxicological analysis results collected by the Victorian Institute of Forensic Medicine (VIFM) for all cases of alleged DFSA in Victoria that occurred between 1st January 2011 - 31st December 2013 were reviewed. Two hundred and four cases of alleged DFSA were identified; complainants were predominately female (93%), and their median age was 26 years (range = 18-54). Self-reported premorbid depression (21.1%) and drug and alcohol abuse (9.8%) were four and two times higher than 12-month prevalence rates in Australia, respectively. All assailants were male, half were known to the complainant and half of alleged assaults occurred in private residences. Most (93.6%) complainants reported voluntary consumption of psychoactive substances prior to the alleged DFSA. Alcohol was the most commonly self-reported substance consumed (n = 164; 64%) and concomitant use of alcohol, prescription and illicit drugs was also commonly self-reported (24%). There were 14 cases that produced a positive toxicology result where the complainant did not report voluntary consumption, which suggests these drugs may have been used covertly to facilitate sexual assault. The results of this study indicate that Females in their mid-20's who exhibit higher rates of mental health concerns represent a sub-group of the Australian population with increased vulnerability to DFSA, which typically occurs in a familiar setting in the context of voluntary alcohol and other substance use.

PURPOSE: A systematic review was undertaken to determine the current global prevalence of drug-facilitated sexual assault (DFSA) reported in adults in order to identify trends in the toxicology findings in DFSA around the world over the past 20 years. METHODS: Databases PubMed, PsycINFO and Scopus were systematically searched using the terms: "drug-facilitated sexual assault", "chemical submission", "date rape", "rape drugs" and "drink-spiking" to identify relevant studies for inclusion in the review. This study focused on adult victims of suspected DFSA aged 16 years and above in which toxicology results were reported. RESULTS: The majority of studies included were published in the United States, followed by the United Kingdom, with only a single study dedicated to this area in both Australia and Europe. Epidemiology, prevalence rates, and toxicology for DFSA appear broadly commensurate across different continents, although there are some differences in how "drug-facilitated sexual assault" is defined, as well as differences in the sensitivity of toxicological analyses. Nonetheless, alcohol is the most commonly detected substance and co-occurrence with other drugs is common. Aside from alcohol there was no other specific drug category associated with DFSA. Cannabinoids and benzodiazepines were frequently detected, but a lack of contextual information made it difficult to establish the extent that these substances contributed to suspected cases of DFSA. CONCLUSIONS: This comprehensive review suggests that alcohol intoxication combined with voluntary drug consumption presents the greatest risk factor for DFSA, despite populist perceptions that covert drink-spiking is a common occurrence. There is a need to develop policies that encourage early responders to suspected DFSA (e.g., law enforcement agencies, medical staff, support agencies, etc), to collect detailed information about the individual's licit and illicit drug consumption history, in order to assist in providing appropriate and more thorough contextual information.

Between January 17, 2003 and August 29, 2003, the Emergency Department admitted a patient who had been surreptitiously intoxicated and robbed of his valuables every Friday. The first cases were considered anecdotal, but criminal activity was rapidly suspected. The cohort includes 16 male Asian patients aged 28-50 years. All the victims had just arrived in Brussels through one of the main rail station of the town and were admitted via the emergency ambulance service from different locations in the centre of Brussels around the CHU Saint-Pierre Hospital. Haemodynamic parameters upon admission were within normal limits. The Glasgow Coma Scale was equal or higher than 9/15 in 14 of the 16 victims. Toxicology screening obtained in 12 patients revealed the presence of flunitrazepam, which was further quantified at levels ranging from 21 to 75 µg/l. One of the Japanese patients, who returned to Belgium afterwards for professional reasons, was approached by the police and accepted to press charges. This allowed the police to investigate and send undercover agents to the railway station on Friday afternoons and evenings. They found a person who was offering welcome cookies to Asian travellers. He arrived from Amsterdam and returned once his crime was committed. Flunitrazepam is well known as a rape drug. We report a series of victims in whom flunitrazepam was used to facilitate robbery.
