[PMID: 38783300 PMCID: PMC11112856 DOI: 10.1186/s12954-024-01024-8] [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: 02/15/2024] [Accepted: 05/15/2024] [Indexed: 05/25/2024] Open
Abstract
BACKGROUND Methylenedioxymethamphetamine (MDMA) is a popular drug worldwide and use is prevalent in Aotearoa New Zealand. Although associated with some significant harms, including fatalities, MDMA is ultimately less harmful than other commonly consumed drugs. We aimed to expand the understanding of MDMA harm and harm reduction strategies from a consumer perspective so that national harm reduction efforts can be better informed. METHODS We conducted 14 semi-structured focus group discussions including 60 people (aged 18-67, median = 21) who use MDMA in the Southern region of Aotearoa New Zealand to explore their thoughts and experiences regarding MDMA associated harm and harm reduction. Reflexive thematic analysis was conducted from a critical realist perspective. RESULTS Five themes were generated; (1) Mindset and setting matters; (2) Looking after your body and mind, not overdoing it; (3) Other substances increase risk and harm; (4) Trusted friends and peers are protective; and (5) Valid information is key for healthy self-determination; and one subtheme 5.1) Drug checking is essential harm reduction. CONCLUSIONS We discuss the implications for MDMA consumers and aim to inform national drug policy and the harm reduction practices of consumers and organisations, for the ultimate purpose of reducing MDMA-related harm in Aotearoa New Zealand.

Abstract
Workplace drug testing (WDT) is essential to prevent drug abuse disorders among the workforce because it can impair work performance and safety. However, WDT is limited by many challenges, such as urine adulteration, specimen selection, and new psychoactive substances (NPS). This review examined the issues related to WDT. Various scientific databases were searched for articles on WDT for drug detection published between 1986 (when WDT started) and January 2024. The review discussed the history, importance, and challenges of WDT, such as time of specimen collection/testing, specimen adulteration, interference in drug testing, and detection of NPS. It evaluated the best methods to detect NPS in forensic laboratories. Moreover, it compared different techniques that can enhance WDT, such as immunoassays, targeted mass spectrometry, and nontargeted mass spectrometry. These techniques can be used to screen for known and unknown drugs and metabolites in biological samples. This review assessed the strengths and weaknesses of such techniques, such as their validation, identification, library search, and reference standards. Furthermore, this review contrasted the benefits and drawbacks of different specimens for WDT and discussed studies that have applied these techniques for WDT. WDT remains the best approach for preventing drug abuse in the workplace, despite the challenges posed by NPS and limitations of the screening methods. Nontargeted techniques using high-resolution liquid chromatography-mass spectrometry (MS)/gas chromatography-tandem MS can improve the detection and identification of drugs during WDT and provide useful information regarding the prevalence, trends, and toxicity of both traditional and NPS drugs. Finally, this review suggested that WDT can be improved by using a combination of techniques, multiple specimens, and online library searches in case of new NPS as well as by updating the methods and databases to include new NPS and metabolites as they emerge. To the best of the author's knowledge, this is the first review to address NPS as an issue in WDT and its application and propose the best methods to detect these substances in the workplace environment.

Fitzgerald ND, Palamar JJ. Increases in the use of drug testing kits among nightclub and festival attendees in New York City who use ecstasy, 2017-2022. Drug Alcohol Rev 2024; 43:975-983. [PMID: 38408742 PMCID: PMC11052675 DOI: 10.1111/dar.13829] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Revised: 02/07/2024] [Accepted: 02/12/2024] [Indexed: 02/28/2024]
Abstract
INTRODUCTION Ecstasy (3,4-methylenedioxymethamphetamine [MDMA]) is a drug commonly used by people who attend electronic dance music (EDM) events at nightclubs and dance festivals. Drug checking has gained popularity in recent years to test for adulterants, but epidemiology studies are needed to estimate potential shifts in prevalence of drug checking to further inform harm reduction efforts. METHODS Adults entering randomly selected EDM events in New York City were surveyed in 2017 and 2022. Those reporting past-year ecstasy use were asked if they tested their ecstasy in the past year using a drug testing kit and whether they found out or suspected their ecstasy contained other drugs. We compared estimates between 2017 and 2022. RESULTS In 2017, an estimated 23.1% had tested their ecstasy, and this estimate increased to 43.1% in 2022 (86.6% increase, p = 0.006). Among those who tested their ecstasy, in 2017, 31.2% always tested their drug, and this increased to 60.6% in 2022 (94.2% increase, p = 0.026). In 2017, 59.6% of those who tested their ecstasy reported finding out or suspecting their drug was adulterated, which decreased to 18.4% in 2022 (69.1% decrease, p < 0.001). Suspected methamphetamine adulteration in particular decreased, from 21.9% in 2017 to 3.6% in 2022 (83.6% decrease, p = 0.007). DISCUSSION AND CONCLUSIONS The use of drug testing kits has increased among EDM event attendees who use ecstasy and, at the same time, among those who had tested their ecstasy, suspected adulteration has decreased. Continued interest in understanding ecstasy contents among this population suggests the need for formal drug checking services.

Metabolic profile of N-ethylhexedrone, N-ethylpentedrone, and 4-chloromethcathinone in urine samples by UHPLC-QTOF-HRMS. J Pharm Biomed Anal 2024; 241:115994. [PMID: 38309098 DOI: 10.1016/j.jpba.2024.115994] [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: 11/10/2023] [Revised: 01/08/2024] [Accepted: 01/18/2024] [Indexed: 02/05/2024]
Abstract
Forensic laboratories are constantly required to identify new drugs and their metabolites. N-ethylhexedrone (NEH, HEXEN), N-Ethylpentedrone (NEP), and 4-Chloromethcathinone (4-CMC, clephedrone) are synthetic substances structurally related to natural cathinone, alkaloid present in the leaves of the Catha edulis (Khat) plant. These synthetic cathinones (SC) are members of the heterogenous family of new psychoactive substances (NPS) that raised major concerns in scientific and forensic communities over the past years due to their widespread consumption. In this context, we investigated their metabolic profile using of UHPLC-QTOF-HRMS to elucidate the distribution of the parent drug and its metabolites in urine samples over time. Initially, both male and female volunteers were divided into three groups and eight subjects of each group were administered intranasally or orally with one SC (20-40 mg of NEH or NEP intranasal, 100-150 mg of 4-CMC oral). Urine samples were collected at 0-2 and 2-4 or 2-5 h. Urine (50 μL) was diluted 1:2 with acetonitrile/methanol (95:5) and injected into the UHPLC-QTOF-HRMS. Phase-I and phase-II metabolites were identified on the basis of fragmentation patterns and exact masses. Several phase-I and glucuronide-phase-II metabolites were identified in urine samples. Keto group reduction, hydroxylation and dealkylation were the common metabolic pathways identified for all cathinones and the presence of NEH-glucuronide, NEP-glucuronide and 4-CMC-glucuronide was also relevant. Significant is the slower metabolite formation for 4-CMC, which was detected at high concentrations in its original form even 5 h after administration, due to its long half-life and low intrinsic clearance compared to the other SCs. UHPLC-QTOF-HRMS demonstrated a considerable capability to semi-quantify the three synthetic cathinones and identify the target metabolites with high reliability. The introduction of new target compounds improves the efficiency of toxicological screening analysis on real samples and extends the window of detection of the SCs in biological matrices.

Abstract
BACKGROUND 3,4-Methylenedioxymethamphetamine (MDMA) is drug of high prevalence in Aotearoa New Zealand and is the primary drug analysed by legal drug checking services. We aimed to address the gap in literature pertaining to MDMA-related harm reduction behaviour and harm experiences within the country. METHODS An online survey was used to assess the harm reduction behaviours (e.g., limiting consumption, planning use, seeking information) of people who use MDMA, in addition to their use of reagent testing and the major national drug checking and harm reduction service, KnowYourStuffNZ. RESULTS In total, 915 people completed the survey (60.7% females, aged 18-65, median = 24, IQR = 20-28). Frequency of various MDMA-related harm reduction behaviours differed, although these were carried out relatively frequently by most participants. Those who reported experiencing harm (physical, psychological, spiritual, social) from MDMA, or another drug presumed to be MDMA, reported less frequent harm reduction behaviours than non-harmed consumers. Reagent testing of MDMA had been conducted by 42.3% of the sample. Approximately 27% of the sample had used KnowYourStuffNZ services. Of KnowYourStuffNZ clients, 95.9% reported learning about harm reduction, and 53.3% reported changing their behaviour because of the service. Reasons for not using the KnowYourStuffNZ service were primarily lack of availability in local area (32.8%) or at relevant events (51.8%), and lack of concern with substance quality (29.8%). MDMA harm was reported by 14.4% of the sample, whilst reported harm was more common from consumption of presumably non-MDMA substances, self-reported as being mistaken for MDMA. Harm was primarily physical or psychological. Potential MDMA dependence was apparent in 6.9% of the sample. CONCLUSIONS The findings highlight potential targets for harm reduction education and interventions and emphasize the need for greater availability of readily accessible drug checking services in Aotearoa New Zealand.

Structure-activity relationships for locomotor stimulant effects and monoamine transporter interactions of substituted amphetamines and cathinones. Neuropharmacology 2024; 245:109827.

Abstract
Substitutions to the phenethylamine structure give rise to numerous amphetamines and cathinones, contributing to an ever-growing number of abused novel psychoactive substances. Understanding how various substitutions affect the pharmacology of phenethylamines may help lawmakers and scientists predict the effects of newly emerging drugs. Here, we established structure-activity relationships for locomotor stimulant and monoamine transporter effects of 12 phenethylamines with combinations of para-chloro, β-keto, N-methyl, or N-ethyl additions. Automated photobeam analysis was used to evaluate effects of drugs on ambulatory activity in mice, whereas in vitro assays were used to determine activities at transporters for dopamine (DAT), norepinephrine (NET), and 5-HT (SERT) in rat brain synaptosomes. In mouse studies, all compounds stimulated locomotion, except for 4-chloro-N-ethylcathinone. Amphetamines were more potent stimulants than their β-keto counterparts, while para-chloro amphetamines tended to be more efficacious than unsubstituted amphetamines. Para-chloro compounds also produced lethality at doses on the ascending limbs of their locomotor dose-effect functions. The in vitro assays showed that all compounds inhibited uptake at DAT, NET, and SERT, with most compounds also acting as substrates (i.e., releasers) at these sites. Unsubstituted compounds displayed better potency at DAT and NET relative to SERT. Para-chloro substitution or increased N-alkyl chain length augmented relative potency at SERT, while combined para-chloro and N-ethyl substitutions reduced releasing effects at NET and DAT. These results demonstrate orderly SAR for locomotor stimulant effects, monoamine transporter activities, and lethality induced by phenethylamines. Importantly, 4-chloro compounds produce toxicity in mice that suggests serious risk to humans using these drugs in recreational contexts.

Abstract
Background Nightclub/festival attendees are a population with high rates of party drug use, but research is needed to determine whether there have been shifts in unintended drug exposure in this population (e.g., via adulterants) to inform prevention and harm reduction efforts. Methods Adults entering nightclubs and festivals in New York City were asked about past-year drug use in 2016 through 2022, with a subset providing a hair sample for testing. We focused on the 1943 who reported ecstasy use (of which 247 had a hair sample analyzed) and compared trends in self-reported drug use, drug positivity, and adjusted prevalence (adjusting for unreported use). Results MDMA positivity decreased from 74.4 % to 42.3 %, and decreases occurred regarding detection of synthetic cathinones ("bath salts"; a 100.0 % decrease), MDA (a 76.9 % decrease), amphetamine (an 81.3 % decrease), methamphetamine (a 64.2 % decrease), and ketamine (a 33.4 % decrease) (ps < .05). Although prevalence of MDA and synthetic cathinone use was comparable between self-report and adjusted report in 2022, gaps in prevalence were wider in 2016 (ps < .01). Adjusted prevalence of synthetic cathinone use decreased more across time than prevalence based on self-report (a 79.4 % vs. 69.1 % decrease) and adjusted report for MDA use decreased more than prevalence based on self-report (a 50.6 % vs. 38.9 % decrease). Conclusions Combining self-report and toxicology tests helped us determine that decreases in drug use/exposure were steeper regarding adjusted prevalence. Underreported drug exposure-possibly due to exposure to adulterants-appears to have had less of an effect on prevalence in 2022 than it did in 2016.

Abstract
A drug concoction called tusi has emerged in Latin America and in Europe and is now beginning to acquire popularity in the United States. "Tusi" is a phonetic translation of "2C," a series of psychedelic phenethylamines. The concoction is also sometimes referred to as "pink cocaine" as it typically comes in the form of pink powder. However, despite its name, the concoction rarely contains 2C series drugs. Multiple drug checking studies have found that the majority of tusi samples contain ketamine, often combined with 3,4-methylenedioxymethamphetamine (MDMA), methamphetamine, cocaine, opioids, and/or new psychoactive substances. The tusi phenomenon complicates the drug landscape because it has the potential to confuse both people who use it and researchers alike. People using may think the drug is 2C/2C-B, and they may also be unaware that the concoction tends to consist of ketamine and a wide variety of other drugs. Unintentional exposure to its contents can lead to increased risk of adverse effects. The tusi phenomenon also has the potential to complicate drug research as unknown exposure to drugs like ketamine and MDMA will lead to underreporting of use. A combination of self-report and toxicological testing may be needed to inform the most accurate estimates of use. Both researchers and people at risk for use need to be informed about this new concoction. Drug researchers need to be cognizant about the way they query use, and people at risk for using need to be educated about the possible contents of tusi and associated dangers.

Abstract
INTRODUCTION People who attend nightclubs and festivals are known for high prevalence of party drug use, but more research is needed on underreporting in this population, in part because unintentional drug exposure through adulterated drug products is common. We examined the prevalence of drug use in this population, based both on self-reporting and on hair test results, with a focus on the detection of underreported use. METHODS Adults entering nightclubs and festivals in New York City were asked about past-year drug use in 2019-2022 (n = 1,953), with 328 providing an analyzable hair sample for testing. We compared trends in self-reported drug use, drug positivity, and "corrected" prevalence, adjusting for unreported use, and delineated correlates of testing positive for ketamine and cocaine after not reporting use (discordant reporting). RESULTS Of the 328 who provided a sample, cocaine and ketamine were the most frequently detected drugs (55.2% [n = 181] and 37.2% [n = 122], respectively), but these were also the two most underreported drugs, with 37.1% (n = 65) and 26.4% (n = 65), respectively, testing positive after not reporting use. Between 2019 and 2022, positivity decreased for cocaine, ketamine, 3,4-methylenedioxy-metamfetamine, and amfetamine, and underreported exposure to cocaine and ketamine also decreased (P < 0.05). Underreporting of the use of these drugs was common, but we also detected underreported exposure to ethylone, fentanyl, 3,4-methylenedioxyamfetamine, metamfetamine, and synthetic cannabinoids. Prevalence of discordant reporting of cocaine use was higher among those testing positive for ketamine exposure (adjusted prevalence ratio = 2.63; 95% CI: 1.48-4.69) and prevalence of discordant reporting of ketamine use was lower post-coronavirus disease caused by the SARS-CoV-2 virus (adjusted prevalence ratio = 0.39; 95% CI: 0.16-0.91) and among those reporting cocaine use (adjusted prevalence ratio = 0.53; 95% CI: 0.32-0.89). DISCUSSION Underreporting of drug use was common, suggesting the need for researchers to better deduce intentional underreporting versus unknown drug exposure via adulterants. CONCLUSIONS Researchers should consider both self-report and toxicology results from biological samples when examining trends in use.

Abstract
Synthetic cathinones (SCs) are a group of new psychoactive substances often referred to as "legal highs" or "bath salts", being characterized by a dynamic change, new compounds continuously emerging on the market. This creates a lack of fast screening tests, making SCs a constant concern for law enforcement agencies. Herein, we present a fast and simple method for the detection of four SCs (alpha-pyrrolidinovalerophenone, N-ethylhexedrone, 4-chloroethcathinone, and 3-chloromethcathinone) based on their electrochemical profiles in a decentralized manner. In this regard, the voltametric characterization of the SCs was performed by cyclic and square wave voltammetry. The elucidation of the SCs redox pathways was successfully achieved using liquid chromatography coupled to (tandem) mass spectrometry. For the rational identification of the ideal experimental conditions, chemometric data processing was employed, considering two critical qualitative and quantitative variables: the type of the electrochemical platform and the pH of the electrolyte. The analytical figures of merit were determined on standard working solutions using the optimized method, which exhibited wide linear ranges and LODs suitable for confiscated sample screening. Finally, the performance of the method was evaluated on real confiscated samples, the resulting validation parameters being similar to those obtained with another portable device (i.e., Raman spectrometer).

Palamar JJ, Le A. Prevalence of self-reported adverse effects associated with drug use among nightclub and festival attendees, 2019-2022. DRUG AND ALCOHOL DEPENDENCE REPORTS 2023; 7:100149. [PMID: 37025564 PMCID: PMC10070077 DOI: 10.1016/j.dadr.2023.100149] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 02/18/2023] [Accepted: 03/20/2023] [Indexed: 06/19/2023]
Abstract
BACKGROUND Research investigating adverse effects from drug use has focused extensively on poisonings and mortality. This study focuses on drug-related adverse effects not necessarily resulting in hospitalization or death among a population known for high prevalence of party drug use-electronic dance music (EDM) nightclub and festival attendees. METHODS Adults entering EDM venues were surveyed in 2019-2022 (n = 1952). Those reporting past-month use of a drug were asked whether they had experienced a harmful or very unpleasant effect after use. We examined 20 drugs and drug classes with a particular focus on alcohol, cannabis, cocaine, and ecstasy. Prevalence and correlates of adverse effects were estimated. RESULTS Almost half (47.6%) of adverse effects involved alcohol and 19.0% involved cannabis. 27.6% of those using alcohol reported an adverse effect, while 19.5%, 15.0%, and 14.9% of participants reported an effect from use of cocaine, ecstasy, and cannabis, respectively. Use of less prevalent drugs, such as NBOMe, methamphetamine, fentanyls, and synthetic cathinones, tended to be associated with higher prevalence of adverse effects. The most consistent risk factor was younger age, while past-month use of a greater number of drugs was often a protective factor against adverse effects. For most drugs, taking too much was the most common perceived reason for the adverse effect, and visiting a hospital after use was most prevalent among those experiencing an adverse effect from cocaine (11.0%). CONCLUSIONS Adverse drug effects are common in this population and results can inform prevention and harm reduction in this population and the general population.

Dual-binding domain electrochemiluminescence biosensing platform with self-checking function for sensitive detection of synthetic cathinone in e-cigarettes. Biosens Bioelectron 2023; 224:114963. [PMID: 36603282 DOI: 10.1016/j.bios.2022.114963] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2022] [Revised: 11/25/2022] [Accepted: 11/27/2022] [Indexed: 11/30/2022]
Abstract
Current single signal electrochemiluminescence (ECL) sensors are susceptible to false positive or false negative phenomena due to experimental conditions. Therefore, sensors with "self-checking" function are attracting democratic attention. In quick succession, a highly sensitive single-cathode dual ECL signal aptasensor with self-checking function to improve the shortcomings mentioned above was designed. This aptasensor used In-based metal-organic framework (MIL-68) as load and stabilizer to effectively attenuate the aggregation-induced quenching (ACQ) effect of porphyrin derivatives (Sn-TCPP) while improve ECL stability. The introduction of cooperative-binding split-aptamers" (CBSAs) aptamers increased the specificity of the aptasensor and its unique double-binding domains detection accelerated the detection efficiency. When analyzing 3,4-methylenedioxypyrovalerone (MDPV), we could calculate two concentrations based on the strength of ECL 1 and ECL 2. If the concentrations are the same, the result would be obtained; if not, it should be retested. Depending on the above operation, the results achieve self-check. It was found that the designed aptasensor could quantify the concentration of MDPV between 1.0 × 10-12 g/L and 1.0 × 10-6 g/L with the limit of detection (LOD) of 1.4 × 10-13 g/L and 2.0 × 10-13 g/L, respectively (3 σ/slope). This study not only improves the detection technology of MDPV, but also explores the dual-signal detection of porphyrin for the first time and enriches the definition of self-checking sensor.

Abstract
BACKGROUND Synthetic cathinones are the most used novel psychoactive substances in Taiwan because they exhibit psychoactive effects similar to those of methamphetamine, inducing acute psychosis, violence, and self-harm. However, the differences in the clinical characteristics of patients with synthetic cathinone and methamphetamine intoxication admitted to psychiatric emergency departments (EDs) remain unclear. METHODS This study recruited patients with stimulant intoxication who were admitted to a psychiatric ED from April 2019 to May 2020. Sociodemographic, lifestyle, and psychopathological data were collected through face-to-face interviews and evaluated. Immunoassay tests and liquid chromatography-quadrupole time-of-flight mass spectrometry were performed to detect substances in urine specimens. The patients were matched by sex and age (in 5-year intervals). The associations between the 2 groups and physical complications were analyzed through logistic regression. RESULTS Twenty-four patients with synthetic cathinone intoxication were identified and matched with 48 patients with methamphetamine intoxication. The 2 groups exhibited similar clinical severity of psychotic symptoms and high risks of violence and self-harm. Both groups were predominated by unmarried patients, unemployed patients, and habitual smokers and drinkers. However, family histories of substance use and criminal records were less prevalent among the patients with synthetic cathinone intoxication, but they had a higher rate of physical complications (odds ratio, 8.55; 95% confidence interval, 2.15-34.03), compared with patients with methamphetamine intoxication. CONCLUSIONS Compared with patients intoxicated with methamphetamine, those intoxicated with synthetic cathinones may have similar tendencies toward psychosis, violence, and self-harm but higher risks of physical complications, which are prioritized in psychiatric EDs.

Perspectives of people in Philadelphia who use fentanyl/heroin adulterated with the animal tranquilizer xylazine; Making a case for xylazine test strips. DRUG AND ALCOHOL DEPENDENCE REPORTS 2022; 4:100074.

Abstract
Background Xylazine is an animal tranquilizer increasingly detected in those who have died of an opioid overdose in Philadelphia, PA and elsewhere. Despite an increasing presence of xylazine in the local fentanyl/heroin drug market and its association with ulcers, there are few perspectives about xylazine from people who use drugs and no data about the utility of a hypothetical xylazine test strip. Methods Between January to May 2021 in Philadelphia, PA, people who used fentanyl/heroin and had previously used fentanyl test strips were queried about xylazine and hypothetical xylazine test strips. Interviews were transcribed and analysis was conducted via conventional content analysis. Results Participants (7 spontaneously, 6 after probing, n = 13) discussed "tranq" (i.e., xylazine) in the fentanyl/heroin supply. None enjoyed tranq or wanted it in their fentanyl/heroin. Participants suspected xylazine saturation of the fentanyl/heroin market, disliked the sensation of the drug, and had safety concerns about xylazine exposure. Participants did not indicate concerns about overdose. All were interested in hypothetical xylazine test strips. While previous literature indicates that some people enjoy tranq in their fentanyl/heroin, our findings differed, with participants expressing concern about the consequences of undesired exposure. The interest expressed for xylazine test strips by people who use fentanyl/heroin is an important opportunity to center their voices in the development of innovations designed to mitigate the harms of unwanted adulterant exposure. Conclusions In the present study, people who use fentanyl/heroin indicated an interest to test their drug for the presence of xylazine prior to use.

Abstract
Synthetic cathinones are used as stimulants of abuse. Many abused drugs, including stimulants, activate nuclear factor-κB (NF-κB) transcription leading to increases in NF-κB-regulated pro-inflammatory cytokines, and the level of inflammation appears to correlate with length of abuse. The purpose of this study was to measure the profile of IL-1α, IL-1β, IL-6, CCL2 and TNF-α in brain and plasma to examine if drug exposure alters inflammatory markers. Male and female Sprague-Dawley rats were trained to self-administer α-pyrrolidinopentiophenone (α-PVP) (0.1 mg/kg/infusion), 4-methylmethcathinone (4MMC) (0.5 mg/kg/infusion), or saline through autoshaping, and then self-administered for 21 days during 1 h (short access; ShA) or 6 h (long access; LgA) sessions. Separate rats were assigned to a naïve control group. Cytokine levels were examined in amygdala, hippocampus, hypothalamus, prefrontal cortex, striatum, thalamus, and plasma. Rats acquired synthetic cathinone self-administration, and there were no sex differences in drug intake. Synthetic cathinone self-administration produced sex differences in IL-1α, IL-1β, IL-6, CCL2 and TNF-α levels. There were widespread increases in inflammatory cytokines in the brains of male rats compared to females, particularly for 4MMC, whereas females were more likely to show increased inflammatory cytokines in plasma compared to saline groups than males. Furthermore, these sex differences in cytokine levels were more common after LgA access to synthetic cathinones than ShA. These results suggest that synthetic cathinone use likely produces sex-selective patterns of neuroinflammation during the transition from use to abuse. Consequently, treatment need may differ depending on the progression of synthetic cathinone abuse and based on sex.

Abstract
In recent years, the availability and the consequent consumption of New Psychoactive Substances (NPS) have proliferated at an unprecedented rate, posing a significant risk to the public health and challenging the law enforcement efforts to tackle the black market. In particular, large availability on Internet and unmonitored shipping have facilitated the diffusion of NPS on national territories. In this scenario, the forensic activity based on the process of drug detection, including investigation, seizure, recognition and analytical identification is crucial to get insights into the drug black market transformation. In this study, we describe the results obtained from the analysis of hundreds of packages seized during the months of year 2020, and suspected to contain NPS because not reacting with standard field test kits. We focused on the analysis by GC-MS and HPLC-HRMS, and NPS in particular, trying to underline the most common molecules present on the Italian territory during the COVID-19 pandemic. NPS were identified in 92.6% of the samples. The most prevalent compounds were synthetic cathinones, and 3-MMC in particular, which alone accounted for 18.6% of the total cases. Other prevalent molecules were 5F-MDMB-PICA, 2-FDCK, 1cp-LSD and 1P-LSD. Fentanyl was never detected. The information obtained from drug seizures is crucial to publish national alerts, which are in turn important to assist the legislative effort to ban new compounds and the update of toxicological and analytical methods.

Abstract
BACKGROUND Drugs like ecstasy, cocaine, and counterfeit prescription pills can contain fentanyl. We examined knowledge about potential adulteration/contamination of such drugs among people attending electronic dance music (EDM) parties. METHODS Adults in New York City were surveyed entering randomly selected EDM parties during the summers of 2018 (n=1,029) and 2019 (n=559). Surveys assessed perceptions that: 1) ecstasy/Molly can contain adulterants more dangerous than MDMA, 2) cocaine can contain fentanyl, and 3) prescription pills from non-pharmacy sources can contain fentanyl. We compared prevalence of perceptions between 2018 and 2019. RESULTS Prevalence of agreeing that cocaine can contain fentanyl increased from 42.1% to 58.6%, a 39.2% increase (p=.003). Increases in agreement were not significant regarding ecstasy potentially containing adulterants (55.0% vs. 59.0%) and non-pharmacy prescription drugs potentially containing fentanyl (46.8% vs. 52.9%). Those reporting past-year ecstasy use in particular reported increased agreement that ecstasy can be adulterated (from 52.9% to 80.0%, a 51.2% increase; p<.001) and those reporting past-year cocaine use reported increased agreement that cocaine can be adulterated (from 48.2% to 70.7%, a 46.7% increase; p=.016). CONCLUSIONS Knowledge of potential adulteration or contamination of commonly used drugs in this high-risk scene is increasing. Continued education about possible drug contents is needed.

Abstract
3,4-Methylenedioxy-N-methylcathinone (methylone) is a new psychoactive substance with stimulant properties and potential for abuse. Despite its popularity, limited studies have examined relationships between brain concentrations of methylone, its metabolites, and pharmacodynamic effects. The goal of the present study was 2-fold: 1) to determine pharmacokinetics of methylone and its major metabolites-4-hydroxy-3-methoxy-N-methylcathinone (HMMC), 3,4-dihydroxy-N-methylcathinone (HHMC), and 3,4-methylenedioxycathinone (MDC)-in rat brain and plasma and 2) to relate brain pharmacokinetic parameters to pharmacodynamic effects including locomotor behavior and postmortem neurochemistry. Male Sprague-Dawley rats received subcutaneous methylone (6, 12, or 24 mg/kg) or saline vehicle (n = 16/dose), and subgroups were decapitated after 40 or 120 minutes. Plasma and prefrontal cortex were analyzed for concentrations of methylone and its metabolites by liquid chromatography-tandem mass spectrometry. Frontal cortex and dorsal striatum were analyzed for dopamine, 5-HT, and their metabolites by high-performance liquid chromatography-electrochemical detection. Brain and plasma concentrations of methylone and its metabolites rose with increasing methylone dose, but brain methylone and MDC concentrations were greater than dose-proportional. Brain-to-plasma ratios for methylone and MDC were ≥ 3 (range 3-12), whereas those for HHMC and HMMC were ≤ 0.2 (range 0.01-0.2). Locomotor activity score was positively correlated with brain methylone and MDC, whereas cortical 5-HT was negatively correlated with these analytes at 120 minutes. Our findings show that brain concentrations of methylone and MDC display nonlinear accumulation. Behavioral and neurochemical effects of systemically administered methylone are related to brain concentrations of methylone and MDC but not its hydroxylated metabolites, which do not effectively penetrate into the brain. SIGNIFICANCE STATEMENT: Behavioral and neurochemical effects of methylone are related to brain concentrations of methylone and its metabolite MDC but not its hydroxylated metabolites, 4-hydroxy-3-methoxy-N-methylcathinone and 3,4-dihydroxy-N-methylcathinone, which do not effectively penetrate into the brain. Methylone and MDC display nonlinear accumulation in the brain, which could cause untoward effects on serotonin neurons in vulnerable brain regions, including the frontal cortex.

Application of a simultaneous screening method for the detection of new psychoactive substances in various matrix samples using liquid chromatography/electrospray ionization tandem mass spectrometry and liquid chromatography/quadrupole time-of-flight mass spectrometry. RAPID COMMUNICATIONS IN MASS SPECTROMETRY : RCM 2021; 35:e9067. [PMID: 33656207 DOI: 10.1002/rcm.9067] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/29/2020] [Revised: 02/01/2021] [Accepted: 02/06/2021] [Indexed: 06/12/2023]
Abstract
RATIONALE Recently, new psychoactive substances (NPS) have emerged as a public health risk. Particularly, their chemical structures are modified to avoid detection. Synthetic NPS with effects similar to those of illegal drugs have been recently detected and synthesized worldwide, including MDMB-FUBINACA and APINAC, making it essential to rapidly and accurately detect NPS. METHODS Fourteen NPS with similar structures were selected and their structures identified using 1 H and 13 C NMR spectroscopy. Additionally, we proposed the fragmentation pattern of each compound using liquid chromatography/quadrupole time-of-flight mass spectrometry (LC/QTOF-MS). A simultaneous analytical method using liquid chromatography/electrospray ionization tandem mass spectrometry (LC/ESI-MS/MS) was also developed and applied to real samples to detect the 14 NPS. The method was validated based on the specificity, linearity, limit of detection (LOD), limit of quantification (LOQ), precision, accuracy, matrix effect, and stability according to international validation guidelines. RESULTS The established method was used to screen 65 different matrix samples using LC/ESI-MS/MS. By comparing the calculated product ion ratios with those of standards, 2C-B in one of the real samples and 5F-MDMB-PICA in 20 samples were identified. For re-confirmation of detected compounds, the fragmentation pattern of each compound was compared with that of each standard using LC/QTOF-MS. CONCLUSIONS In this study, LC/QTOF-MS data were used to elucidate the structures and fragmentation patterns of 14 NPS. A simultaneous method was developed using LC/ESI-MS/MS, which was applied to 65 real samples. The presented method and results can assist in ensuring the safety of public health from illegal adulteration.

Abstract
Stimulant-induced neurochemical changes may occur at different times for different brain regions or neurotransmitter systems. This study sought to examine the behavioral and neurochemical effects of extended access to α-pyrrolidinopentiophenone (α-PVP) and 4-methylmethcathinone (4MMC). Male and female Sprague-Dawley rats were trained to self-administer α-PVP (0.1 mg/kg/infusion) or 4MMC (0.5 mg/kg/infusion) through autoshaping, and then self-administered for 21 days during 1 h (short access; ShA) or 6 h (long access; LgA) sessions. Separate rats were assigned to a naïve control group. Amygdala, hippocampus, hypothalamus, prefrontal cortex (PFC), striatum, and thalamus were extracted, and tissue was analyzed with electrochemical detection and liquid chromatography mass spectrometry. Rats acquired self-administration of α-PVP and 4MMC, and LgA rats showed more escalation of self-administration than ShA rats. Synthetic cathinone administration produced several effects on neurotransmitters. LgA self-administration of α-PVP increased 5-HIAA levels in all brain regions, compared to control. In contrast, both LgA and ShA 4MMC self-administration decreased 5-HT and 5-HIAA levels in most brain regions. LgA exposure to both synthetic cathinones increased DOPAC levels in hypothalamus and striatum, and increased HVA levels in striatum compared to control. LgA self-administration of either synthetic cathinone produced region-specific increases in NE levels, whereas ShA self-administration lowered NE levels in select locations compared to control. These alterations in neurotransmitter levels indicate that synthetic cathinone use may produce differential neurochemical changes during the transition from use to abuse, and that 21 days of self-administration only models the beginning stages of dysregulated drug intake.

Abstract
The emergence of new psychoactive drugs in the market demands rapid and accurate tools for the on-site classification of illegal and legal compounds with similar structures. Herein, a novel method for the classification of synthetic cathinones (SCs) is presented based on their electrochemical profile. First, the electrochemical profile of five common SC (i.e., mephedrone, ethcathinone, methylone, butylone, and 4-chloro-alpha-pyrrolidinovalerophenone) is collected to build calibration curves using square wave voltammetry on graphite screen-printed electrodes (SPEs). Second, the elucidation of the oxidation pathways, obtained by liquid chromatography-high-resolution mass spectrometry, allows the pairing of the oxidation products to the SC electrochemical profile, providing a selective and robust classification. Additionally, the effect of common adulterants and illicit drugs on the electrochemical profile of the SC is explored. Interestingly, a cathodic pretreatment of the SPE allows the selective detection of each SC in presence of electroactive adulterants. Finally, the electrochemical approach is validated with gas chromatography-mass spectrometry by analyzing 26 confiscated samples from seizures and illegal webshops. Overall, the electrochemical method exhibits a successful classification of SC including structural derivatives, a crucial attribute in an ever-diversifying drug market.

Abstract
Background Synthetic cathinones are a category of psychostimulants belonging to the growing number of designer drugs also known as “Novel Psychoactive Substances” (NPS). In recent years, NPS have gained popularity in the recreational drug market due to their amphetamine-like stimulant effects, low cost, ease of availability, and lack of detection by conventional toxicology screening. All these factors have led to an increase in NPS substance abuse among the young adults, followed by spike of overdose-related fatalities and adverse effects, severe neurotoxicity, and cerebral vascular complications. Much remains unknown about how synthetic cathinones negatively affect the CNS and the status of the blood-brain barrier (BBB). Methods We used in vitro models of the BBB and primary human brain microvascular endothelial cells (hBMVEC) to investigate the effects of the synthetic cathinone, 4-methyl methcathinone (mephedrone), on BBB properties. Results We showed that mephedrone exposure resulted in the loss of barrier properties and endothelial dysfunction of primary hBMVEC. Increased permeability and decreased transendothelial electrical resistance of the endothelial barrier were attributed to changes in key proteins involved in the tight junction formation. Elevated expression of matrix metalloproteinases, angiogenic growth factors, and inflammatory cytokines can be explained by TLR-4-dependent activation of NF-κB signaling. Conclusions In this first characterization of the effects of a synthetic cathinone on human brain endothelial cells, it appears clear that mephedrone-induced damage of the BBB is not limited by the disruption of the barrier properties but also include endothelial activation and inflammation. This may especially be important in comorbid situations of mephedrone abuse and HIV-1 infections. In this context, mephedrone could negatively affect HIV-1 neuroinvasion and NeuroAIDS progression.

Abstract
Synthetic cathinones are phenylalkylamine compounds related to natural cathinone from Catha edulis leaves. Due to their sympathomimetic effects comparable to common illicit drugs, these substances are mainly drugs of abuse and constitute the second most frequently seized group of new psychoactive substances. In order to ensure their regulation and to promote public health, reliable analytical tools are required to track these substances. In the present study, we developed a CE hyphenated to laser-induced fluorescence detection method to demonstrate its suitability to perform fast and cost-effective synthetic cathinones analysis. Fourteen compounds including isobaric compounds and position isomers were selected to encompass the large panel of chemical structures. To separate the FITC-labeled analytes (presenting the same negative charge and close mass to charge ratios), MEKC separation mode was selected. Method selectivity was not suitable using common surfactants. In this context, alkyl polyethylene glycol ether surfactants were successfully used as neutral surfactant to overcome this analytical challenge. The effect of surfactant nature on separation performances and migration behaviors of the analytes was also studied. Optimal BGE composition included 75 mM borate buffer at pH 9.3 and 0.4 mM of C12E10 surfactant. Final MEKC separation conditions were proposed to analyze a large panel of synthetic cathinones. This method helped to reach a sensitivity with LOD from 0.1 to 0.4 nM (pg/mL order).

Abstract
Synthetic cathinone derivatives are commonly considered quasi-legal alternatives for stimulant drugs, such as cocaine and methamphetamine, but some derivatives are increasingly being detected in club drug formulations of Ecstasy or 'Molly' as substitutes for methylenedioxymethamphetamine (±-MDMA). Although several studies have evaluated the psychostimulant-like effects of synthetic cathinones, few cathinone compounds have been assessed for MDMA-like activity. In order to determine their likelihood of interchangeability with entactogenic club drugs, the discriminative stimulus effects of methcathinone, 4-fluoromethcathinone, 4-methylmethcathinone, 4-methylethcathinone, 3-fluoromethcathinone, pentedrone, and ethylone were assessed in Sprague-Dawley rats trained to discriminate 1.5 mg/kg racemic methylenedioxymethamphetamine (±-MDMA) from vehicle. Methamphetamine and the cathinones 4-fluoromethcathinone, 4-methylmethcathinone, 4-methylethcathinone, 3-fluoromethcathinone, pentedrone, and ethylone fully substituted for the discriminative stimulus effects of ±-MDMA. In contrast, methcathinone produced a maximum of only 43% ±-MDMA-appropriate responding and higher doses suppressed responding. Most, but not all of the cathinone compounds tested have discriminative stimulus effects similar to those of MDMA as well as psychostimulant-like effects; however, the potency of MDMA versus psychostimulant substitution varies substantially among the compounds, suggesting that a subset of synthetic cathinones are more MDMA-like than psychostimulant-like. These findings further highlight the highly-variable pharmacology of this class of compounds and suggest that those cathinones with MDMA-like effects may also have increased use as club drugs.

Abstract
BACKGROUND Adolescent patients with a substance use disorder (SUD) often fulfil the criteria for a co-occurring post-traumatic stress disorder (PTSD). However, it is not clear if these dual-diagnosed adolescents present with unique levels of substance use and how their substance use relates to PTSD symptom clusters. OBJECTIVE To investigate substance use in adolescents with co-occurring PTSD and SUD. Additionally, we explored how the use of specific substances is related to specific PTSD symptom clusters. METHOD We recruited n = 121 German adolescent SUD patients, in three groups: no history of traumatic events (TEs) (n = 35), TEs but not PTSD (n = 48), probable PTSD (n = 38). All groups were administered a trauma questionnaire and were asked to report their past-month substance use. RESULTS Adolescents with probable PTSD and SUD report a higher frequency of MDMA use than adolescents with no PTSD and no TE (PTSD vs. noTE: U = 510.5, p = .016; PTSD vs. TE: U = 710.0, p = .010). The use of MDMA was more frequent in adolescents with avoidance symptoms (X2 (1) = 6.0, p = .014). Participants report using substances at a younger age (PTSD vs. noTE: U = 372.0, p = .001; PTSD vs. TE: U = 653.5, p = .022) and PTSD symptom onset was on average 2.2 years earlier than first MDMA use (t (26) = -2.89, p = .008). CONCLUSIONS Adolescent SUD patients with probable PTSD are more likely to use MDMA than SUD patients without PTSD. The use of MDMA was associated with reported avoidance symptoms. The first age of MDMA use is initiated after PTSD onset. It is unclear whether the association of MDMA use with avoidance symptoms is due to efforts to reduce these symptoms or a result of regular MDMA use.

Abstract
Understanding the stability of analyzed drugs in biological samples is a crucial part for an appropriate interpretation of the analytical findings. Synthetic cathinones, as psychoactive stimulants, belong to a major class of new psychoactive substances. As they are subject to several degradation pathways, they are known to clinical and forensic toxicologists as unstable analytes in biological samples. When interpreting analytical data of synthetic cathinones in biological samples, analysts must be aware that the concentration of analytes may not accurately reflect the levels at the time they were acquired owing to many factors. This review provides (i) an overview of the current scientific knowledge on the stability of synthetic cathinones and/or metabolites in various human biological samples with a focus on factors that may deteriorate their stability-such as storage temperature, length of storage, matrix, pH, type of preservatives, concentration of analytes, and the chemistry of the analytes-and (ii) possible solutions on how to avoid such degradation. The PubMed database as well as Google Scholar was thoroughly searched to find published studies on the stability of synthetic cathinones since 2007 by searching specific keywords. A total of 23 articles met the inclusion criteria and were included in this review. Synthetic cathinones that carry methylenedioxy or N-pyrrolidine ring showed higher degradation resistance over other substituted groups. Acidification of samples pH plays a crucial role at increasing the stability of cathinones even with analytes that were frequently considered as poorly stable. This review also provides several recommendations for best practice in planning the experimental design, preservation, and storage conditions in order to minimize synthetic cathinones' degradation in human biological samples.

Abstract
Synthetic cathinones are the second most commonly seized new psychoactive substance family in Europe. These compounds have been related to several intoxication cases, including fatalities. Although the pharmacological effects, metabolism, and pharmacokinetics of cathinones have been studied, there is little information about the permeability of these compounds through the blood-brain barrier (BBB). This is an important parameter to understand the behavior and potency of cathinones. In this work, 13 selected cathinones have been analyzed in telencephalon tissue from Sprague-Dawley rats intraperitoneally dosed at 3 mg/kg. Our results revealed a direct relationship between compound polarity and BBB permeability, with higher permeability for the more polar cathinones. The chemical moieties present in the cathinone had an important impact on the BBB permeability, with lengthening of the α-alkyl chain or functionalization of the aromatic ring with alkyl moieties resulting in lower concentration in telencephalon tissue. Our data suggest that transport of cathinones is a carrier-mediated process, similar to cocaine transport across the BBB.

Abstract
Background Ecstasy (3,4-methylenedioxymethamphetamine [MDMA]), commonly referred to as Molly in the US, is commonly adulterated with drugs potentially more dangerous than MDMA. Synthetic cathinones ("bath salts") are common adulterants, and use of these compounds tends to be stigmatized. We investigated whether presenting information on the extent of ecstasy being adulterated with "bath salts" affects intentions to use. Methods A total of 1,025 adults entering electronic dance music parties were surveyed in 2018. Using an experimental posttest-only design with random assignment, half were randomly assigned to view a published Vice headline about ecstasy/Molly commonly being adulterated with "bath salts." Results Overall, 30.5% of the sample reported past-year ecstasy use, and before viewing the headline, 16.4% agreed that ecstasy/Molly commonly contains "bath salts." While controlling for pre-test knowledge of "bath salt" adulteration, viewing the headline reduced the odds of intention to use ecstasy/Molly only among non-past-year ecstasy users (Odd ratio [OR] = 0.54; p = .048). Viewing the headline increased the odds (OR = 1.81, p = .030) of past-year ecstasy users' intention to test their ecstasy for adulterants. Conclusions Knowledge that ecstasy is commonly adulterated may help reduce the risk for future use among non-recent users and increase the willingness of users to test their ecstasy. This information can be used to target those at risk for ecstasy/Molly use.

Abstract
Synthetic cathinones, commonly referred to as "bath salts," are powerful amphetamine-like psychostimulants, and new derivatives are constantly appearing in the illicit market to evade judicial consequences. To keep up with these new stimulant drugs, a low-sample-size liquid chromatography-tandem mass spectrometry method was validated to quantify 30 synthetic cathinones in postmortem blood including N-ethylpentylone and eutylone. Mixed mode cation exchange solid-phase extraction using 0.25 mL postmortem blood was performed followed by detection using a triple quadrupole mass spectrometer operating electrospray ionization in positive mode. The reversed-phase chromatographic separation was achieved in 16 min, resolving all isobaric compounds. The linear range of the calibration curve was 1-500 ng/mL (R 2 > 0.99) for all compounds. Limit of quantification (LOQ) and limit of detection were determined to be at 1 ng/mL. Both imprecision and bias were evaluated and had met all allowed criteria (CV and bias <20%). No matrix effect was observed with values ranging from -5.1 to 13.3% (CV 11.4-17.5%, n = 10). Extraction efficiency (84.9-91.5%) and process efficiency (86.1-102.6%) were satisfactory, except for 4-chloroethcathinone which was 63 and 64.9%, respectively. No carryover after the upper LOQ was detected. Neither endogenous nor exogenous interferences were observed. Both dilution integrity and stability (24 h) yielded acceptable results. This method was applied to 18 postmortem cases received between 2015 and 2019. Eight different synthetic cathinones were detected in selected postmortem cases within the past 5 years, showing a wide range of concentrations from 1.4 to >500 ng/mL. While ethylone and methylone were detected in 2015, cases between 2016 and 2017 were predominantly butylone, dibutylone, pentylone and N-ethylpentylone which had also exhibited a significant increase in 2018. To our knowledge, this method is the most comprehensive methodology for the determination of up-to-date synthetic cathinones currently available in whole blood.

Abstract
A bio-inspired nanodevice for the selective and sensitive fluorogenic detection of 3,4-methylenedioxypyrovalerone (MDPV), usually known as Cannibal drug, is reported. The sensing nanodevice is based on mesoporous silica nanoparticles (MSNs), loaded with a fluorescent reporter (rhodamine B), and functionalized on their external surface with a dopamine derivative (3), which specifically interacts with the recombinant human dopamine transporter (DAT), capping the pores. In the presence of MDPV, DAT detaches from the MSNs consequently, causing rhodamine B release and allowing drug detection. The nanosensor shows a detection limit of 5.2 μM, and it is able to detect the MDPV drug both in saliva and blood plasma samples.

Abstract
BACKGROUND AND OBJECTIVES Electronic dance music (EDM) party attendees who use ecstasy (3,4-methylenedioxymethamphetamine [MDMA], Molly) are at high risk for ingesting adulterant drugs, but little is known regarding trends in exposure. We sought to determine whether adulteration has shifted in recent years. METHODS Adults entering EDM events at nightclubs and dance festivals in NYC were surveyed in 2016 and 2019. We tested hair samples from a subsample of those reporting past-year ecstasy use using ultra-high performance liquid chromatography-tandem mass spectrometry. Differences in unreported drug exposure and suspected adulteration were compared between 2016 (n = 90) and 2019 (n = 72). RESULTS MDMA detection was stable at 72-74%. We detected decreases in unreported use of methamphetamine (from 22.2% to 5.6% [P = .003], an 74.8% decrease), new psychoactive substances (from 31.1% to 2.8% [P < .001], a 91.0% decrease), and synthetic cathinones in particular (from 27.8% to 2.8% (P < .001, an 89.9% decrease). Unreported ketamine exposure increased from 18.9% to 34.7% (P = .022, an 83.6% increase). We also detected decreases in participants' suspicion of their ecstasy being adulterated with methamphetamine (from 20.0% to 5.6% [P = .010], an 72.0% decrease) and "bath salts" (synthetic cathinones, from 8.9% to 1.4% [P = .044], an 84.3% decrease). DISCUSSION AND CONCLUSIONS Unknown exposure to adulterants among people who use ecstasy in the EDM scene is shifting. Monitoring of exposure to adulterants is needed to inform harm reduction. SCIENTIFIC SIGNIFICANCE This was among the first studies to examine unintentional exposure to drugs over time in this population and unintentional exposure to synthetic cathinones in particular appears to be declining.

Abstract
BACKGROUND AND OBJECTIVES Electronic dance music (EDM) party attendees are at high risk for drug use. However, little is known regarding the extent of underreporting of drug use in this population, in part, because use of synthetic drugs is often associated with unknown exposure to adulterant drugs. We estimated the extent of underreported drug use in this population by comparing self-reported use to hair toxicology results. METHODS Time-space sampling was used to survey adults entering EDM events at nightclubs and dance festivals in New York City from January through August of 2019. Seven hundred ninety-four adults were surveyed and 141 provided analyzable hair samples. We queried past-year use of >90 drugs and tested hair samples using ultra-high performance liquid chromatography-tandem mass spectrometry. We compared hair test results to past-year self-reported use and adjusted prevalence estimates by defining use as reporting use or testing positive. Correlates of discordant reporting, defined as testing positive after not reporting use, were estimated. RESULTS Prevalence of drug use increased when considering positive hair tests in estimates, with 43.8% of participants testing positive for at least one drug after not reporting use. For example, based on self-report, cocaine use prevalence was 51.1%, and increased by a factor of 1.6 to a prevalence of 80.0% when adding hair test results to self-report. Younger adults (ages 18-25), black and other/mixed race participants, those reporting "other" sexuality, and those with a college degree were at significantly higher risk for testing positive for drugs not reportedly used. Those who self-reported using more types of drugs were less likely to test positive after not reporting use (adjusted prevalence ratio = 0.53, 95% confidence interval = 0.41-0.68). CONCLUSIONS We detected underreporting of drug use, particularly cocaine and ketamine. More research is needed to determine whether this is driven by intentional underreporting or unknown exposure through adulterants.

Abstract
Intention and willingness to use drugs are proximal predictors of drug use; however, willingness to use requires more research to inform prevention efforts. This study examines willingness to use drugs among electronic dance music (EDM) party attendees, a population at high risk for drug use. Data were examined from a repeated cross-sectional study of 2,426 adult EDM party attendees surveyed entering nightclubs and festivals in New York City from 2017 to 2019 using time-space sampling. Trends and correlates of reporting whether participants would use ten different synthetic drugs if offered by a friend in the next thirty days were examined. Ecstasy (31.9%), powder cocaine (25.5%), LSD (20.0%), and opioids (16.4%) were most likely to be used if offered. Willingness to use powder cocaine, LSD, ketamine, amphetamine, tryptamines, and 2C series drugs significantly increased from 2017 to 2019, particularly powder cocaine (increasing from 19.1% to 34.2%, p <.001). Any or more recent use of each drug was associated with increases in willingness to use. Past drug use is a consistent predictor of willingness to use if offered, and willingness to use is increasing in this population. Findings can inform prevention efforts by allowing better targeting of those at risk for use.

Abstract
OBJECTIVE Electronic dance music (EDM) party attendees are a high-risk population for drug use and associated adverse effects. We examined trends in past-year drug use within this population to better inform prevention and harm reduction efforts. METHODS Each summer from 2016 through 2019, we used time-space sampling to survey a cross-section of adults entering EDM parties at randomly selected nightclubs and at dance festivals in New York City. Ns ranged from 504 (2019) to 1,087 (2016). We estimated log-linear trends in past-year use of 16 different synthetic drugs or drug classes. RESULTS Between 2016 and 2019, estimated past-year prevalence of use of ketamine increased from 5.9% to 15.3% (a 157.6% relative increase; P = .007), LSD use increased from 9.9% to 16.6% (a 67.7% relative increase, P < .001), powder cocaine use increased from 17.3% to 35.2% (a 103.5% relative increase, P < .001), and GHB use increased from 1.0% to 4.2% (a 311.8% relative increase; P = .002). Past-year use of >3 drugs increased from 12.7% to 20.5% (a 61.4% relative increase; P = .013); however, estimated past-year use of unknown powders decreased from 2.0% to 1.1% (a relative 44.7% decrease; P = .038) and ecstasy/MDMA/Molly use was stable across years (at 25.0 to 28.5 %; P = .687). CONCLUSIONS Reports of powder cocaine, LSD, ketamine, and GHB are becoming more prevalent among EDM party attendees. Prevention and harm reduction efforts are needed to address increasing use. Research is also needed to examine whether increasing media coverage of medical use of ketamine and other psychedelics affects prevalence of recreational use.

Abstract
BACKGROUND Drug use is prevalent among electronic dance music (EDM) party attendees, but research is needed to determine the extent of adverse drug-related outcomes in this population in order to better inform prevention and harm reduction efforts. METHOD 1029 adults were surveyed entering EDM parties in New York City in 2018. Those reporting past-year use of a drug were asked if they experienced a harmful or very unpleasant effect after use in which they were concerned about their immediate safety. They were also asked about co-use of other drugs and whether they sought help. RESULTS We estimate that a third (33.5%) of EDM party attendees have experienced a drug-related adverse effect in the past year. Two-thirds (67.8%) of adverse effects involved use of alcohol. Relative to use, adverse effects most commonly resulted from use of opioids (e.g., prescription opioid misuse, 41.2%) or alcohol (33.9%). Among those reporting an adverse effect, concomitant use of other drugs was common, particularly among users of LSD (56.5%), ketamine (56.3%), cocaine (55.7%), and ecstasy/MDMA/Molly (47.7%). Adverse effects resulting from synthetic cathinone ("bath salt") use were most likely to result in a hospital visit (57.1%). CONCLUSION Adverse effects from drug use are common among those in the EDM party scene and polydrug use appears to be a common risk factor. More research is needed, however, to determine the extent of event-specific adverse outcomes. Results can inform prevention and harm reduction efforts in this population.

"Flakka" use among high school seniors in the United States. Drug Alcohol Depend 2019; 196:86-90. [PMID: 30709657 PMCID: PMC6377311 DOI: 10.1016/j.drugalcdep.2018.12.014] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/26/2018] [Revised: 12/10/2018] [Accepted: 12/11/2018] [Indexed: 11/21/2022]
Abstract
BACKGROUND Use of synthetic cathinones, commonly referred to as "bath salts", has been associated with tens of thousands of emergency department visits in the US; however, few national studies have estimated prevalence of use and we know very little about use among adolescents. In this study we estimate prevalence and correlates of use of "Flakka" (alpha-PVP), a highly-potent "bath salt" associated with at least 80 deaths in the US. METHODS We analyzed data from the 2016/2017 Monitoring the Future study, which surveyed a nationally representative sample of high school seniors in the US (n = 3786). Bivariable and multivariable models were used to determine demographic and drug-related correlates of use. RESULTS Overall, 0.8% (95% CI: 0.5-1.2) of high school seniors in 2016/2017 is estimated to have used Flakka in the past year. Students whose parents have less than a high school education were at higher odds for use (aOR = 4.12, 95% CI: 1.00-16.94). Flakka users reported high prevalence of use of other drugs, particularly synthetic cannabinoids (85.6%), ketamine (72.3%), marijuana (59.1%), and GHB (47.5%). Flakka use was also associated with use of a higher number of other drugs and higher frequency of use of other drugs, with 51.7% using 4-12 other drugs and 22.4% using 4-12 other drugs >6 times. CONCLUSIONS Students who use multiple drugs are elevated risk for Flakka use, suggesting synthetic cathinone use alone is rare and the use of multiple substances may compound adverse effects of these drugs. Socio-economic disparities are concerning given reduced access to prevention and intervention.

Abstract
OBJECTIVES This study aims to examine patterns and first mentions of reported use of new or uncommon drugs across 13 years, among nationally representative samples in the United States. METHODS Participants (ages ≥12) in the National Surveys on Drug Use and Health (2005-2017, N = 730,418) were provided opportunities to type in names of new or uncommon drugs they had ever used that were not specifically queried. We examined self-reported use across survey years and determined years of first mentions. RESULTS From 2005 to 2017, there were 2,343 type-in responses for use of 79 new or uncommon synthetic drugs, and 54 were first-ever mentions of these drugs. The majority (65.8%) of mentions were phenethylamines (e.g., 2C-x, NBOMe), which were also the plurality of new drug mentions (n = 22; 40.7%). Mentions of 2C-x drugs in particular increased from 30 mentions in 2005 to 147 mentions in 2013. We estimate an upward trend in use of new or uncommon drugs between 2005 and 2017 (p < 0.001). CONCLUSION Although type-in responses on surveys are limited and underestimate prevalence of use, such responses can help inform researchers when new compounds are used. Continued surveillance of use of new and uncommon drugs is needed to inform adequate public health response.

Drug Use by Music Festival Attendees: A Novel Triangulation Approach Using Self-Reported Data and Test Results of Oral Fluid and Pooled Urine Samples. Subst Use Misuse 2019; 54:2317-2327. [PMID: 31398072 DOI: 10.1080/10826084.2019.1646285] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 10/26/2022]
Abstract
Background: Self-reported data are commonly used when investigating illicit substance use. However, self-reports have well-known limitations such as limited recall and socially desirable responding. Mislabeling or adulteration of drugs on the illicit market may also cause incorrect reporting. Objectives: We aimed to examine what could be gained in terms of illicit drug use findings among music festival attendees when including biological sample test results in the assessment. Methods: We included 651 attendees at three music festivals in Norway from June to August 2016. Self-reported drug use was recorded using questionnaires, and samples of oral fluid were analyzed to detect use of illicit drugs. In addition, we analyzed samples of pooled urine from portable toilets at each festival. Results: All methods identified cannabis, MDMA, and cocaine as the most commonly used drugs. Overall, 6.6% of respondents reported use of illicit substances during the previous 48 hours. Oral fluid testing identified a larger number of drug users as 12.6% tested positive for illicit drugs. In oral fluid testing, we identified ketamine and three new psychoactive substances (NPS) that had not been reported on the questionnaire. In pooled urine testing, we identified amphetamine and three additional NPS that were neither reported used nor found in oral fluid samples. Conclusions/Importance: Drug testing of biological samples proved to be an important supplement to self-reports as a larger number of illicit substances could be detected.
