Prego-Meleiro P, Recalde-Esnoz I, Sordo L, Del Castillo H, García-Ruiz C, Montalvo G, López-Cuadrado T. Drug-facilitated sexual assault in youth nightlife contexts in Spain. Public Health 2024; 233:157-163. [PMID: 38901300 DOI: 10.1016/j.puhe.2024.05.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2023] [Revised: 04/10/2024] [Accepted: 05/17/2024] [Indexed: 06/22/2024]
Abstract
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.

Abstract
This cross-sectional study aimed to assess the association between drugs and alcohol intake and sexual abuse in adolescents, otherwise defined as Drug Facilitated Sexual Assault (DFSA). We considered the survivors who accessed care at the Centre "Soccorso Violenza Sessuale" (SVS - Sexual Violence Relief Centre) in Turin (Italy), between May 2003 and May 2022. We found that 973 patients aged 13-24 among which 228 were victims of DFSA. Epidemiological and anamnestic aspects of the episode of sexual violence were examined, with a specific focus on investigating the alcohol and/or drug intake as reported by the victim, along with the results of the toxicological analysis. the study further accounts for the variations caused by the COVID-19 pandemic on DFSA-related accesses. Our findings show that 23% of adolescents accessing care at SVS were subjected to DFSA. Six out ten adolescents knew their aggressor, at times a partner (10%) oran acquaintance (43%). In 12% of cases violence was perpetrated by a group of people (12%). Almost 90% of young victims described alcohol consumption, while 37% reported drug use at the time of the assault. Alcohol taken alone or in combination with other substances was the most detected drug in our sample throughout the period considered. Given the large use of psychoactive substances among adolescents, it is imperative to implement harm reduction strategies alongside educational activities aimed at fostering awareness about consent. Health personnel should be trained to manage the needs of victims of DFSA clinically and forensically.

Abstract
Since the last two decades, the scientific community has made an effort to analyze drug-facilitated sexual assault (DFSA). However, a lack of understanding remains about the DFSA problem, particularly concerning the opportunistic variant. Facing this situation, a systematic review of the term DFSA is carried out from its first appearance in the scientific databases consulted (Web of Science, Scopus, and PubMed) to the current day. The search resulted in 773 publications, reduced to a final study sample composed of 19 articles. Eligible studies for this review had to meet certain inclusion criteria, in addition to providing information on DFSA prevalence, DFSA victim profile, DFSA offender profile, involved drugs, or contextual information about the assault. The results demonstrated that the assailants are men, who mostly know victims before the assault. The victims are young women under 30 years old. Alcohol is the drug involved in most DFSA cases, prevailing a voluntary use. Most assaults occur in private spaces, particularly the aggressors' own homes. Furthermore, there is a detected need for a standard definition of DFSA to allow the different actors involved in dealing with sexual violence to work effectively together, and, at the same time, it is detected that the available studies overrepresent proactive DFSA and underestimate opportunism, the most common modus operandi involved in DFSA cases.

Synthetic cathinones in drug-facilitated sexual assault: A case report involving the novel generation substituted cathinone N-ethylpentedrone and a review of the literature. Forensic Sci Int 2024; 359:112030. [PMID: 38657324 DOI: 10.1016/j.forsciint.2024.112030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Revised: 04/05/2024] [Accepted: 04/17/2024] [Indexed: 04/26/2024]
Abstract
The use of 3,4-methylenedioxymethamphetamine (MDMA) in drug-facilitated sexual assault (DFSA) is not uncommon. Indeed, the effects associated with the use of this substance may lead to disinhibition. Several synthetic cathinones, such as mephedrone or methylone, also possess marked entactogenic properties. This manuscript aims to (i) report a DFSA case involving a novel cathinone derivative, namely N-ethyl-pentedrone (NEPD) and (ii) review previously reported DFSA cases involving synthetic cathinones. Using liquid chromatography-high-resolution mass spectrometry (LC-HRMS), NEPD was detected in both plasma and urine collected from a 36-year-old male who had been victim of DFSA. Furthermore, an exhaustive, non-period-specific English-language literature search was performed using several different electronic databases to identify DFSA cases involving synthetic cathinones. Overall, five synthetic cathinones have been associated with DFSA:methylenedioxypyrovalerone, 4-methylethcathinone, α -pyrrolidinopentiophenone, mephedrone, α -pyrrolidinohexiophenone, and methylone, which appears to be the most frequently reported. Methylone is the β-keto analog of MDMA, with which it shares substantial pharmacological similarities. Indeed, the pharmacological effects of methylone are similar to those associated with MDMA. By contrast, little is known regarding NEPD's pharmacological effects in humans. Based on subjective reports, NEPD can produce both positive and negative effects in human. Unlike what is reported in the case of methylone or mephedrone, only a small minority of NEPD users report slightly entactogenics effects. Such properties theoretically make NEPD more suitable for use in a chemsex context than in DFSA context; even though, the boundary between these two specific forms of sexualized drug use can sometimes appear tenuous.

Abstract
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.

Abstract
Analyzing urine is common in drug-facilitated sexual assault cases if the analysis of blood is not optimal. The efficient enzymatic pretreatment of urine is important for cleaving glucuronides and improving the detection of the parent drug. The aim was to investigate the efficiency of three β-glucuronidases on eleven glucuronides relevant to DFSA at different incubation periods and temperatures. Human drug-free urine was fortified with 11 glucuronides, hydrolyzed with either β-glucuronidase/arylsulfatase (Helix Pomatia), recombinant β-glucuronidase B-One™ or recombinant β-glucuronidase BGTurbo™ and incubated for 5, 10, 60 min, 18 h and 24 h at 20 °C/40 °C/55 °C before UHPLC-MS/MS analysis. The stability of 141 drugs and metabolites relevant to DFSA was investigated by incubating fortified urine under the same hydrolysis conditions. B-One™ showed efficient hydrolysis (>90%) of most glucuronides in 5 min at all temperatures, while BGTurbo™ showed a similar efficiency (>90%), but the optimal temperature (20-55 °C) and incubation time (5-60 min) varied among analytes. The β-glucuronidase/arylsulfatase had the lowest efficiency and required the longest incubation (24 h) at 40-55 °C. The stability of 99% of 141 drugs and metabolites was not affected by incubation at 20-55 °C for 24 h. Recombinant enzymes show promising results for the simple and efficient hydrolysis of a broad panel of glucuronides relevant for DFSA.

Abstract
Drug facilitated-crime or chemical submission (DFC/CS) is defined as the concealed or forced administration of psychoactive substances to a victim for criminal purposes. This is a national program set up in the early 2000 s in the form of a prospective multicenter survey, the results of which this manuscript presents. Over this 19-year period, 5487 cases were collected, analyzed and classified into 54 % of suspected cases, 29 % of chemical vulnerability (CV) cases and 17 % of proven DFC/CS cases. In the overall data, the most prevalent victims were female (81 %), with an average age of 27 years. Sexual assault was the most frequent aggression (77 %), followed by theft (14 %). Victims of proven DFC/CS cases were from of all ages including children and elderly. In 934 victims of DFC/CS, 100 various psychoactive substances were detected mostly represented by benzodiazepines and z-drugs (55 %), various sedatives including antihistamines (16 %) and non-therapeutic substances (16 %). Gamma-hydroxybutyric acid (GHB) was found in 4 % cases. In CV cases, alcohol (90 %) and cannabis (32 %) intake were mainly involved. In France, despite prevention messages, DFC/CS has been an epidemic for many years and has been proven by our national study. This national program has the aim to identifying the substances used but unfortunately not the goal to fight against this phenomenon. Since 2009, we observed a new modus operandi of the aggressors who pose as taxi drivers facilitating the reception of the victims leaving nightclubs. We can emphasize that GHB is not the "date rape drug" but rather the benzodiazepine class is.

Abstract
A simple and highly efficient ultrasound assisted membrane-assisted solvent extraction (MASE) pre-treatment method for urine has been developed and validated for the simultaneous determination of twenty-two drugs involved in drug-facilitated sexual assaults (DFSAs) by liquid chromatography-tandem mass spectrometry. MASE was performed with 4.0 mL of urine (pH adjusted at 12), 400 μL of hexane as an organic solvent inside the polypropylene membrane, and ultrasonication (45 kHz, 120 W) for 10 min. A pre-concentration factor of 40 was achieved after evaporation (N2 stream) and re-dissolution in 100 µL of methanol. Analytes were separated using a Zorbax Eclipse Plus C18 column under gradient elution with aqueous 10 mM NH4HCO3 (pH 8.0) and methanol as mobile phases. Matrix-matched calibrations allowed the assessment of DFSA drugs of quite different octanol-water partition coefficients (Ko/w), from 1.32 101 for pregabalin to 2.45 105 for clomipramine (Log P values from 1.12 (pregabalin) to 5.39 (clomipramine)). The limit of detection (LOD) was between 0.0075 to 0.37 µg L-1, with analytical recoveries ranging from 73 to 103%, and relative standard deviations (RSDs) within the 2-20% range. The applicability of the method was demonstrated after analysing urine samples under forensic investigation.

Gamma-hydroxybutyrate (GHB), 1,4-butanediol (1,4BD), and gamma-butyrolactone (GBL) intoxication: A state-of-the-art review. Regul Toxicol Pharmacol 2023; 142:105435.

Abstract
γ-hydroxybutyrate (GHB) is synthesized endogenously from γ-aminobutyric acid (GABA) or exogenously from 1,4-butanediol (butane-1,4-diol; 1,4-BD) or γ-butyrolactone (GBL). GBL, and 1,4-BD are rapidly converted to GHB. The gastric absorption time, volume of distribution, and half-life of GHB are between 5 and 45 min, 0.49 ± 0.9 L/kg, and between 20 and 60 min, respectively. GHB and its analogues have a dose-dependent effect on the activation of GHB receptor, GABA-B, and GABA localized to the central nervous system. After ingestion, most patients present transient neurological disorders (lethal dose: 60 mg/kg). Chronic GHB consumption is associated with disorders of use and a withdrawal syndrome when the consumption is discontinued. GHB, GBL, and 1,4-BD are classified as narcotics but only the use of GHB is controlled internationally. They are used for drug facilitated (sexual) assault, recreational purposes, slamsex, and chemsex. To confirm an exogenous intake or administration of GHB, GBL, or 1-4-BD, the pre-analytical conservation is crucial. The antemortem cutoff doses for detection are 5 and 5-15 mg/L, with detection windows of 6 and 10 h in the blood and urine, respectively Control of GHB is essential to limit the number of users, abuse, associated risks, and death related to their consumption.

Melchior SE, Nielsen MKK, Oropeza AR, Banner J, Johansen SS. Detection of scopolamine in urine and hair in a drug-facilitated sexual assault. Forensic Sci Int 2023; 347:111678. [PMID: 37030199 DOI: 10.1016/j.forsciint.2023.111678] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Revised: 03/16/2023] [Accepted: 04/03/2023] [Indexed: 04/08/2023]
Abstract
The use of the drug scopolamine in drug-facilitated crimes is known. Nevertheless, given the high potency of the drug and its rapid metabolism, analysis in blood and urine may not be sufficient for drug detection in late crime declaration, especially following a single-dose administration in drug-facilitated sexual assault (DFSA) cases. Hair may constitute an essential supplemental matrix extending the drug detection window in such cases. This case report presents quantitative data on scopolamine findings in urine and hair in a DFSA case. A young female had consumed several alcoholic drinks at a party venue when her behaviour became noticeably peculiar. Later, she woke up next to an unknown man and had no recollection of the night's events. Blood and urine samples were collected 18 h after the incident. The initial toxicological target screening using UHPLC-TOF-MS detected scopolamine in the hydrolysed urine sample, and quantification yielded 41 µg/L scopolamine in urine, while blood was negative. Segmental hair analysis using multitarget UHPLC-MS/MS was performed on three washed 2-cm segments of hair collected five weeks after the incident, yielding 0.37 pg/mg scopolamine only in the relevant hair segment. This case report provides novel insight into the concentration in hair following a single exposure of scopolamine and the feasibility of detecting scopolamine in hair by comparison to published toxicological findings.

Abstract
Sexual assault casework requires the collaboration of multiple agency staff to formalise an investigative pipeline running from crime scene to court. While the same could be said of many other forensic investigations, few require the additional support of health care staff and the combined forensic involvement of body-fluid examiners, DNA experts and analytical chemists. The sheer amount of collaborative effort between agencies is laid out through a detailed examination of the investigative workflow from crime scene to courtroom with each step in the pipelines detailed and discussed. Beginning with a review of sexual assault legislation in the United Kingdom this article details how sexual assault investigations are initiated by police and supported by sexual assault referral centre (SARC) staff who are often the first responders providing primary healthcare and patient support to victims while simultaneously collecting and assessing forensic evidence. Detailing the myriad of evidential material that can be documented and collected at the SARC, the review identifies and categorises key forensic tests to first detect and identify body-fluids recovered from evidence through to the secondary analysis of DNA to help identify the suspect. This review also focusses on the collection and analysis of biological material used to support the allegation that the sexual activity was non-consensual and provides a breakdown of common marks and trauma as well as a review of common analytical methods used to infer Drug Facilitated Sexual Assault (DFSA). The culmination of the investigative pipeline is discussed by reviewing the Rape and Serious Sexual Assault (RASSO) workflow used by the Crown Prosecution Service before providing our thoughts on the future of forensic analysis and possible changes to the described workflows.

Abstract
Gamma-hydroxybutyric acid (GHB) is a common drug of abuse, and the detection of a consumption or administration is a longstanding research objective in clinical and forensic toxicology. However, until now, the short detection window of GHB could not be enlarged by the use of GHB metabolites. Therefore, new biomarkers for the detection of a GHB intake are needed. In analogy to phosphatidylethanols as long-time biomarkers of ethanol, phospholipids with GHB might represent a promising compound class. While the availability of reference compounds often represents a bottleneck in clinical and forensic toxicological research, two phospholipids-phosphatidyl-GHB (16:0/18:1) and its isomer phosphatidyl beta-hydroxybutyric acid (16:0/18:1)-were successfully synthesized by a new highly versatile synthetic route. Structural characterization data, together with 1 H-, 13 C-, and 31 P-NMR and high-resolution mass spectrometry (HRMS) spectra, are reported. Subsequently, a HPLC-MS/MS method was established for the determination of both compounds (limits of detection [LOD] ≤ 2 ng/ml), and the formation of these metabolites was investigated in two in vitro experiments. The formation of phosphatidyl-GHB (16:0/18:1) was observed in an incubation experiment by converting phosphatidylcholine (16:0/18:1) and GHB with phospholipase D and in whole blood samples spiked with 50 mM GHB, respectively. Therefore, phosphatidyl-GHB (16:0/18:1) might represent a valuable new metabolite of GHB with the potential for an extension of the detection window as GHB biomarker.

Abstract
A cross-sectional study was conducted that describes the characteristics of sexual violence episodes related to the intake of alcohol and drugs observed among women that turned to the "Centro Soccorso Violenza Sessuale" (SVS) of the Sant'Anna Hospital in Turin between 1 January 2008, and 31 December 2017. Two hundred twenty-two patients were enrolled, 25 of which were minors, 141 were Italians, and most of them knew their aggressor and were raped in a private home. One hundred and fifty-five of them declared to the healthcare personnel to have taken alcoholic substances and/or drugs in conjunction with the event (86 reported having drunk alcohol, 36 having taken drugs and 33 disclosed both alcohol and drug abuse). If the woman knew her abuser, alcohol consumption was described as voluntary in more than 80% of cases, while in relation to drugs the consumption was equally voluntary or fraudulent. About 73% of women who reported having drunk alcohol just had amnesia or amnesia related to other symptoms, while amnesia was present in about 63% of women who reported only drug use. Physicians observed physical injuries on 156 women. Patients who reported to have assumed alcohol presented a significantly higher risk to suffer any physical injury and have a significantly increased risk to suffer injuries to their head and/or neck. The results obtained underline how even in Northern Italy alcohol intake represents the most widespread psychoactive substance in case of drug-facilitated sexual assault. There is therefore a need to promote education and prevention campaigns among citizens, especially among the youngest.

Abstract
Drug-facilitated sexual assault is a form of sexual violence against an individual incapacitated by alcohol and/or drugs consumed voluntarily or covertly administered. The purpose of this study was to evaluate toxicological results and the associated demographics of sexual assault-related cases submitted to Houston Forensic Science Center from 2014 to 2020. In total, 1240 samples (1230 cases) were tested during the six-year period that consisted of blood, urine, or both specimens. Blood was analyzed for ethanol by dual-column headspace gas chromatography with flame ionization detection. Drug screen analysis was performed preferably on urine specimens using enzyme-linked immunosorbent assay. Positive screening results were confirmed upon request only due to laboratory policy. A total of 22% (n = 176) of requested samples were confirmed positive. Ethanol was the most prevalent substance detected, present in 17% of the samples (n = 212), followed by 11-nor-9-carboxy-delta-9-tetrahydrocannabinol (THC-COOH) (n = 118). The combination of ethanol and THC-COOH was the most frequent one found (n = 17) in cases positive for two or more drugs (n = 101). Demographic data showed the majority of DFSA victims were white (25%) females (72%) with an average age of 27 years old (n = 348). Almost 90% of cases where the presence of drugs was confirmed resulted in no charges being made, either due to lack of suspect information or unknown reasons by the laboratory.

Abstract
The incidence of drug-facilitated sexual assault (DFSA) has dramatically increased in the last decades. Forensic analytical scientists continuously seek new methods and specimens to prove the incidence of intoxication for the judiciary system. Factors influencing sample selection include the ease of obtaining the samples and the window of detection of the drugs, among others. Both conventional (blood, urine) and non-conventional specimens (hair, nails, fluids) have been proposed as suitable in DFSA cases. Reported sample treatments include a variety of liquid-liquid and solid-phase extraction as well as dilute-and-shoot procedures and microextraction techniques. Regarding analysis, liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) has emerged as the preferred confirmatory technique, due to its sensitivity, selectivity, and wide-scope applicability. In this review, we critically discuss the most common specimens and sample treatments/analysis procedures (related to LC-MS/MS) that have been reported during the last ten years. As a final goal, we intend to provide a critical overview and suggest analytical recommendations for the establishment of suitable analytical strategies in DFSA cases.

Abstract
The expanding and dynamic market of new psychoactive substances (NPSs) poses challenges for laboratories worldwide. The retrospective data analysis (RDA) of previously analyzed samples for new targets can be used to investigate analytes missed in the first data analysis. However, RDA has historically been unsuitable for routine evaluation because reprocessing and reevaluating large numbers of forensic samples are highly work- and time-consuming. In this project, we developed an efficient and scalable retrospective data analysis workflow that can easily be tailored and optimized for groups of NPSs. The objectives of the study were to establish a retrospective data analysis workflow for benzodiazepines in whole blood samples and apply it on previously analyzed driving-under-the-influence-of-drugs (DUID) cases. The RDA workflow was based on a training set of hits in ultrahigh-performance liquid chromatography–quadrupole time-of-flight–mass spectrometry (UHPLC-QTOF-MS) data files, corresponding to common benzodiazepines that also had been analyzed with a complementary UHPLC–tandem mass spectrometry (MS/MS) method. Quantitative results in the training set were used as the true condition to evaluate whether a hit in the UHPLC-QTOF-MS data file was true or false positive. The training set was used to evaluate and set filters. The RDA was used to extract information from 47 DBZDs in 13,514 UHPLC-QTOF-MS data files from DUID cases analyzed from 2014 to 2020, with filters on the retention time window, count level, and mass error. Sixteen designer and uncommon benzodiazepines (DBZDs) were detected, where 47 identifications had been confirmed by using complementary methods when the case was open (confirmed positive finding), and 43 targets were not reported when the case was open (tentative positive finding). The most common tentative and confirmed findings were etizolam (n = 26), phenazepam (n = 13), lorazepam (n = 9), and flualprazolam (n = 8). This method efficiently found DBZDs in previously acquired UHPLC-QTOF-MS data files, with only nine false-positive hits. When the standard of an emerging DBZD becomes available, all previously acquired DUID data files can be screened in less than 1 min. Being able to perform a fast and accurate retrospective data analysis across previously acquired data files is a major technological advancement in monitoring NPS abuse.

Abstract
The best evidence provided in the literature worldwide suggests the importance of harmonizing the investigation in drug-related fatalities. In this study, the application of a multidisciplinary approach in eight cases of drug-related deaths is presented. Although death scene findings could be highly suggestive of drug intoxication, external examination and toxicological screening test alone are insufficient. There are several variables, and it is not always easy to give the proper interpretation of the drug detection. A complete autopsy is necessary to correctly complete organ and tissues sampling for further histological and toxicological studies and obtain body fluids. The use of peripheral blood is recommended to avoid artifacts. The collection of many specimens is warranted to get more responses. The sampling aims to provide a picture of the distribution of the substance in the body. The sample and the selection of the drugs and the matrices to investigate are case-dependent. The presented diagnostic algorithm provides the coroner with all the elements to investigate drug-related deaths and cooperate with toxicologists. Toxicological forensic diagnosis is still extremely heterogeneous in regional and national contexts. Funding for method development, research, networking, facilities, and technologies improvement is mandatory to standardize the toxicological investigation.

Abstract
Drug-facilitated sexual assault (DFSA) is a crime where the victim is unable to provide sexual consent due to incapacitation resulting from alcohol or drug consumption. Due to the large number of substances possibly used in DFSA, including illicit, prescription and over-the-counter drugs, DFSA faces many toxicological challenges. Benzodiazepines (BZDs) are ideal candidates for DFSA, as they are active at low doses, have a fast onset of action and can be easily administered orally. The last decade has seen the emergence of designer benzodiazepines (DBZDs), which show slight modifications compared with BZDs and similar pharmacological effects but are not controlled under the international drug control system. DBZDs represent an additional challenge due to the number of new entities regularly appearing in the market, their possibly higher potency and the limited knowledge available on their pharmacokinetic and pharmacodynamics properties. Many BZDs and DBZDs have a short half-life, leading to rapid metabolism and excretion. The low concentrations and short time windows for the detection of BZD in body fluids require the use of highly sensitive analysis methods to enable the detection of drugs and their respective metabolites. This review discusses the current state of the toxicological analysis of BZDs and DBZDs in forensic casework and their pharmacokinetic properties (i.e., absorption, distribution, metabolism, and elimination), as well as their analysis in biosamples typically encountered in DFSA (i.e., blood, urine and hair).

Comparison of Two Immunoassay Screening Methods and a LC-MS/MS in Detecting Traditional and Designer Benzodiazepines in Urine. Molecules 2021; 27:molecules27010112. [PMID: 35011344 PMCID: PMC8746686 DOI: 10.3390/molecules27010112] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2021] [Revised: 12/17/2021] [Accepted: 12/21/2021] [Indexed: 12/02/2022] Open
Abstract
Sensitive and specific immunoassay screening methods for the detection of benzodiazepines in urine represent an important prerequisite for routine analysis in clinical and forensic toxicology. Moreover, emerging designer benzodiazepines force labs to keep their methodologies updated, in order to evaluate the reliability of the immunochemical techniques. This study aimed at evaluating the sensitivity and specificity of two different immunoassay methods for the detection of benzodiazepines in urine, through a comparison with the results obtained by a newly developed liquid chromatographic tandem mass spectrometric (LC-MS/MS) procedure. A cohort of authentic urine samples (N = 501) were processed, before and after a hydrolysis procedure, through two immunoassays and an LC-MS/MS method. The LC-MS/MS target procedure was optimized for monitoring 25 different molecules, among traditional and designer benzodiazepines, including some metabolites. At least one of the monitored substances was detected in 100 out of the 501 samples. A good specificity was observed for the two immunoassays (>0.99), independently of the cut-offs and the sample hydrolysis. The new kit demonstrated a fairly higher sensitivity, always higher than 0.90; in particular, a high cross-reactivity of the new immunoassay was observed for samples that tested positive for lorazepam and 7-aminoclonazepam. The two immunoassays appeared adequate to monitor not only traditional benzodiazepines but also new designer ones.

Abstract
The aim of this work was to develop a new method for the determination of selected substances from the date-rape drugs group: ketamine, benzodiazepines and cocaine. The method is based on the dried blood spot method which seems to be a suitable tool in the analysis of tested substances. The extraction process based on microwave-assisted extraction was optimized to enable optimal conditions for the isolation of a wide range of analytes from blood samples collected on DBS cards. The extraction with ethyl acetate with a buffer of pH = 9 carried out at a temperature of 50 °C for 15 min ensured high extraction efficiency of the tested analytes. The optimized method was validated. Limits of detection (LOD = 4.38–21.1 ng/mL) and quantification (LOQ = 14.6–70.4 ng/mL), inter- and intra-day precision (CV = 1.37–13.4% and 3.39–14.8%, respectively), recovery (RE = 93.0–112.4%) and matrix effect (ME = 98.4–101.6%) were determined. The validation results indicate the possibility of using the proposed method in the analysis of real blood samples collected from victims of sexual assault.

Ethanol enhanced MDPV- and cocaine-induced aggressive behavior in mice: Forensic implications. Drug Alcohol Depend 2021; 229:109125. [PMID: 34763230 DOI: 10.1016/j.drugalcdep.2021.109125] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2021] [Revised: 09/10/2021] [Accepted: 09/30/2021] [Indexed: 11/20/2022]
Abstract
BACKGROUND Reports concerning the causal link between aggressive behavior and use and abuse of different substances (i.e., alcohol, MDPV) can be found in the literature. Nonetheless, the topic concerning the effects of acute ethanol administration on MDPV and cocaine induced aggressive behavior has yet to be thoroughly investigated. The aim of this study was to investigate such synergistic effects. MATERIALS AND METHODS A total of 360 male mice were employed in the study. Ethanol was diluted with saline solution and administered 10 min before MDPV or cocaine injection via oral gavage needles. Similarly, MDPV and cocaine were dissolved in saline solution and administered by intraperitoneal injection. Different associations of specific drug doses were then tested. To investigate the acute effects of MDPV and cocaine and their interaction with ethanol on aggression in mice, a resident-intruder test was used. RESULTS Ethanol alone was ineffective at dosages of 0.05 g/kg and 0.25 g/kg but increased the aggressiveness of the mice at 0.125 g/kg. Similarly, the injection of both cocaine alone and MDPV alone did not significantly increase the aggressiveness of the mice; conversely, the combination of ethanol and cocaine and ethanol and MDPV enhanced aggression at specific ethanol dosages (0.05 g/kg and 0.125 g/kg). CONCLUSION This study demonstrated that acute ethanol administration enhances MDPV- and cocaine-induced aggressive behavior in mice. This aggressive response is particularly enhanced when MDVP and cocaine are coupled with specific ethanol dosages, proving that psychostimulant drugs may act synergistically under certain conditions.

Development of a New LC-MS/MS Screening Method for Detection of 120 NPS and 43 Drugs in Blood. SEPARATIONS 2021.

Abstract
In the last few years, liquid chromatography coupled with mass spectrometry (LC/MS) has been increasingly used for screening purposes in forensic toxicology. These techniques have the advantages of low time/resource-consuming and high versatility and have been applied in numerous new multi-analytes methods. The new psychoactive substance (NPS) phenomenon provided a great impulse to this wide-range approach, but it is also important to keep the attention on “classical” psychoactive substances, such as benzodiazepines (BDZ). In this paper, a fully validated screening method in blood for the simultaneous detection of 163 substances (120 NPS and 43 other drugs) by a dynamic multiple reaction monitoring analysis through LC-MS/MS is described. The method consists of a deproteinization of 200 µL of blood with acetonitrile. The LC separation is achieved with a 100 mm long C18 column in 35 min. The method was very sensitive, with limits of quantification from 0.02 to 1.5 ng/mL. Matrix effects did not negatively affect the analytical sensitivity. This method proved to be reliable and was successfully applied to our routinary analytical activity in several forensic caseworks, allowing the identification and quantification of many BDZs and 3,4-methylenedioxypyrovalerone (MDPV).

Abstract
Endogenous nature of GHB represents a critical issue for forensic toxicologists, especially in alleged sexual assaults. Therefore, discrimination between physiologically and additional amounts from exogenous sources of such a substance must be effective and reliable in order to avoid severe misinterpretation. This study aimed to quantify the GHB baseline concentrations in chest and pubic hairs collected from 105 healthy volunteers, non-consumers of any drugs of abuse. The final scope was to investigate if these keratin matrices could represent valid alternative to scalp hair when not available. Moreover, we also evaluated the age and gender influences on the GHB baseline levels. 25 mg of hair were incubated overnight with NaOH at 56 °C. After acidification with H2SO4, the solution was liquid-liquid extracted with ethyl acetate and a trimethylsilyl derivatization was then achieved. Analysis was performed in gas chromatography-mass spectrometry in single ion monitoring mode (m/z 233, 234, 147 for GHB; m/z 239, 240 and 147 for GHB-d6). The endogenous amount in "blank" hair was estimated by the standard addition method (0.301 for chest hair and 0.235 ng/mg for pubic hair). GHB concentration ranged from 0.205 to 1.511 ng/mg for chest hair and from 0.310 to 1.913 ng/mg for pubic hair. These values were consistent with previous studies on scalp hair and on pubic hair. Unfortunately, research on chest hair is not available in literature. T-Test and Linear Regression highlighted no statistically significant differences for the two matrices and for all age/gender sub-groups. However, further studies are required to estimate a reliable cut-off value for these keratin matrices. For the first time, we demonstrated the suitability of chest and pubic hair to detect endogenous levels of GHB.

Abstract
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.

Increasing awareness of the severity of female victimization by opportunistic drug-facilitated sexual assault: A new viewpoint. Forensic Sci Int 2020; 315:110460.

Abstract
The victimization of women by opportunistic drug-facilitated sexual assault in leisure contexts was studied in this work by applying a novel approximation. A multifocal analytical strategy based on an intersectional gender-sensitive approach was used to analyse the evidence coming from both forensic case studies and contextual studies about sexual interrelation and drug use. The process of victimization comprises social changes affecting consumption patterns and sexual interaction, intersecting in the hegemonic recreational nightlife model. However, victims experience a range of situations that make it difficult for them to self-acknowledge themselves as such. Widespread myths about the victimization process add to the social questioning faced by victims, stemming from gender-based double standards which condition the expected female behaviors regarding the use of drugs and sexual interaction. The victims usually experience amnesia, lack of injuries and emotional harm, which make difficult the self-acknowledgement as a victim of sexual assault and the reporting of the episode suffered. Consequently, it is an urgent public health need to implement a new viewpoint about the victimization of women by opportunistic drug-facilitated sexual assault in leisure contexts, able to increase awareness of the severity of this form of sexual violence. Society must recognize the existence of this problem within itself to help victims to acknowledge themselves as such, lodge a complaint and seek adequate help. The lack of this social support feeds the perpetuation of the victimization process, which exacerbates the risk of locking victims into spirals of cyclical re-victimization and favors both the underreporting as well as inadequate coping strategies. In addition to focusing on the need to increase awareness of the severity of female victimization by opportunistic drug-facilitated sexual assault in leisure contexts, other recommendations include the use of the term "take advantage", the development of specific criminal approaches, and the in-depth knowledge of the phenomenon via victimization surveys. These steps are necessary for developing well-targeted and evidence-based preventive measures consistent-with-reality.

Abstract
Abstract
Gamma-hydroxybutyric acid (GHB), usually reported as rape drug in drug-facilitated sexual assaults (DFSA), is an endogenous substance in human body and is also found in many beverages. This may lead to data misinterpretation in forensic cases. Herein, we aimed to collect evidence about natural GHB presence in 13 energy drinks (ED). After a liquid–liquid extraction with acidic ethyl acetate, samples were derivatized with BSTFA 1% TMCS. Analyses were carried out by a GC–MS system in SIM mode (GHB, 233, 234, 143 and 147 m/z; GHB-d6, 239, 240, 120 and 206 m/z). GHB was present in all the samples at very low concentrations ranging from 98 to 197 ng/mL. Thus, GHB presence in ED is not exclusively related to exogenous addition. Since the GHB levels are far lower than the minimum active dose (i.e., 0.5 g), it is not expected to induce any effect.

Abstract
In last years, international and national Institutions have been completely focused on the new psychoactive substances (NPS) phenomenon. Many contrast policies have been planned in order to control their spread. Even scientific entities, such as our Forensic Toxicology Division, have spent time and resources for NPS identification in biological (from clinical and forensic caseworks) and non-biological (seized material) samples. Last reports show a low prevalence of NPS across the Europe and Italy, while the classical drugs are still the main cause of drug-related deaths. In particular, a worrisome datum is represented by the increasing number of deaths due to heroin. Seen these statistics, is the NPS phenomenon overestimated? Is the interest in classical drugs decreased? Were we diverted by NPS?
