Byrska B, Stanaszek R. Chemical composition of Ecstasy tablets seized in Poland between 2005 and 2020. Forensic Toxicol 2024:10.1007/s11419-024-00691-3. [PMID: 39017813 DOI: 10.1007/s11419-024-00691-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Accepted: 05/30/2024] [Indexed: 07/18/2024]
Abstract
PURPOSE The most commonly associated substance found in Ecstasy tablets is MDMA (3,4-methylenedioxymethamphetamine). In our study, we showed how the composition of psychoactive ingredients in Ecstasy tablets seized on the drug market in Poland has changed in the years 2005-2020. METHODS The study material consisted of nearly 20,000 single Ecstasy tablets seized by representatives of law enforcement (the police, prosecutors) from 2005 to 2020 and analysed by the Institute of Forensic Research, Krakow, Poland. The analysis of the tablets was carried out by gas chromatography-mass spectrometry (GC-MS), high-performance liquid chromatography with diode array detection (HPLC-DAD) and ultra-high-performance liquid chromatography with photodiode array detection (UHPLC-PDA). RESULTS Currently, new types of MDMA tablets are introduced onto the market, available in various colours and shapes. Our study showed that tablets sold on the street as Ecstasy have variable purity and sometimes contain little or no MDMA. The mean content of MDMA in one tablet seized in 2005-2011 decreased from 90 to 50 mg. In 2013, Ecstasy tablets with a very high MDMA content (average 195 mg per tablet) appeared on the market, but in the next 2 years, the MDMA content decreased again. From 2016, the average MDMA content began to rise again, ranging from 60 to 280 mg. CONCLUSION Tablets sold as Ecstasy also contained completely different psychoactive substances, including new psychoactive substances (NPS) (found in almost 20% of all examined tablets sold as Ecstasy) belonging to different chemical groups or their dangerous combinations (i.e. phenylethylamines, piperazines, tryptamines, cathinones, arylalkylamines, arylcyclohexylamines and piperidines). Such a large variety of psychoactive substances in Ecstasy tablets is associated with a high risk for users unaware of their composition.

Abstract
A new class of synthetic cannabinoids called OXIZIDs has emerged in recent years. This class consists of compounds with oxindole cores and hydrazide/hydrazone linker moieties and has often been described as being designed to circumvent a Chinese class-wide ban that was effective as of 1 July 2021. However, through hair testing of nightclub attendees in New York City-a high-risk population for recreational drug use-we have evidence suggesting exposures to an OXIZID called BZO-4en-POXIZID (4en-pentyl MDA-19) prior to the effective ban. Through analysis of 6 cm segmented hair samples from attendees collected in 2021, we detected five cases of exposure. Specifically, we detected a cluster of three cases based on hair samples collected on 20 June 2021, and then two additional cases from samples collected on 16 July 2021. Four of these hair samples were long enough to analyze two 6 cm hair segments (representing approximately two 6-month timeframes) and three of four of these cases tested positive for repeated exposure (for an estimated exposure over 6 months prior to hair collection). All cases included young adult females reporting past-year cannabis use but all tested negative for tetrahydrocannabinol exposure. Three cases also reported past-year use of cocaine, ecstasy, and/or ketamine, and four cases tested positive for exposure to cocaine, 3,4-methylenedioxymethamphetamine (MDMA), 3,4-methylenedioxyamphetamine (MDA), methamphetamine and/or eutylone. These subjects were exposed to BZO-4en-POXIZID-likely as an adulterant in other drugs, and these cases are among the first documented cases which occurred approximately half a year before the Chinese legislative ban.

Harm Reduct J 2023; 20:174. [PMID: 38053148 PMCID: PMC10698886 DOI: 10.1186/s12954-023-00905-8] [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: 04/05/2023] [Accepted: 11/17/2023] [Indexed: 12/07/2023] Open
Abstract
BACKGROUND Perception of drug adulteration has increased in Mexico, but there is little research on adulterants and toxicity. The aim of this study was to identify drug composition in an electronic music outdoor festival nearby Mexico City. METHODS The participants completed a questionnaire with demographic data, harm reduction strategies, drug-use patterns, history, and the drug they expected to find. We took a small sample of each substance and prepared it for drug checking. A two-section drug testing station was placed within the grounds of the festival. Interaction with participants occurred at the front part. Drug checking was conducted at the rear part. The service was free of charge, voluntary and confidential. Forty persons aged 22 to 48 years participated (mode = 28), of which 92.5% were male, most (82.5%) were single. Through the Substance Analysis Program of "ReverdeSer Collective," we conducted the testing with the attendants that provided 51 drug samples, following ethical and biosafety protocols. We used colorimetry, Fourier Transform Infrared Spectroscopy, and fentanyl immunoassay strips for sample analysis. RESULTS Substances of choice among attendants were psychostimulants (MDMA and other amphetamine-like drugs) and hallucinogens. Most samples contained what the users expected plus adulterants. Main adulterants were methylene-dioxy-ethyl-amphetamine, methylene-dioxy-propyl-amphetamine, hydroxyamphetamine, and the selective serotonin reuptake inhibitor venlafaxine. Fentanyl was present in 2 out of 4 cocaine samples and in 14 of the 22 confirmed MDMA samples. CONCLUSIONS Some of the adulterants found pose serious health risks, especially fentanyl, amphetamine-like substances, and venlafaxine. Therefore, it is urgent to monitor these adulterants at electronic music festivals and to implement prevention, treatment, and harm reduction public policies. Naloxone distribution and drug-assisted therapies should be part of government programs in Mexico.

DRUG AND ALCOHOL DEPENDENCE REPORTS 2023; 9:100198. [PMID: 38023341 PMCID: PMC10665664 DOI: 10.1016/j.dadr.2023.100198] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Accepted: 10/26/2023] [Indexed: 12/01/2023]
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.

Drug Alcohol Depend 2023; 252:110985. [PMID: 37826988 PMCID: PMC10688611 DOI: 10.1016/j.drugalcdep.2023.110985] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 09/19/2023] [Accepted: 09/28/2023] [Indexed: 10/14/2023]
Abstract
BACKGROUND Overdose deaths involving stimulants and opioids simultaneously have raised the specter of widespread contamination of the stimulant supply with fentanyl. METHODS We quantified prevalence of fentanyl in street methamphetamine and cocaine, stratified by crystalline texture, analyzing samples sent voluntarily to a public mail-in drug checking service (May 2021-June 2023). Samples from 77 harm reduction programs and clinics originated in 25 US states. Sample donors reported expected drug and physical descriptions. Substances were identified by gas chromatography-mass spectrometry. Negative binomial models were used to calculate fentanyl prevalence, adjusting for potential confounders related to sample selection. We also examined if xylazine changed donors' accuracy of detecting fentanyl. RESULTS We analyzed 718 lab-confirmed samples of methamphetamine (64%) and cocaine (36%). The adjusted prevalence of fentanyl was 12.5% (95% CI: 2.2%, 22.9%) in powder methamphetamine and 14.8% (2.3%, 27.2%) in powder cocaine, with notable geographic variation. Crystalline forms of both methamphetamine (Chisq=57, p<0.001) and cocaine (Chisq=18, p<0.001) were less likely to contain fentanyl: less than 1% of crystal methamphetamine (2/276) and no crack cocaine (0/53). Heroin was present in 6.6% of powder cocaine samples. Xylazine reduced donors' ability to detect fentanyl, with correct classification dropping from 92% to 42%. CONCLUSIONS Fentanyl was detected primarily in powder forms of methamphetamine and cocaine. Recommended interventions include expanding community-based drug checking, naloxone and fentanyl test strip distribution for people who use stimulants , and supervised drug consumption sites. New strategies to dampen variability in street drug composition are needed to reduce inadvertent fentanyl exposure.

Does chronic use of amphetamine-type stimulants impair interference control? - A meta-analysis. Neurosci Biobehav Rev 2023; 146:105020.

Abstract
In substance use and addiction, inhibitory control is key to ignoring triggers, withstanding craving and maintaining abstinence. In amphetamine-type stimulant (ATS) users, most research focused on behavioral inhibition, but largely neglected the equally important subdomain of cognitive interference control. Given its crucial role in managing consumption, we investigated the relationship between interference control and chronic ATS use in adults. A database search (Pubmed & Web of Science) and relevant reviews were used to identify eligible studies. Effect sizes were estimated with random effects models. Subgroup, meta-regression, and sensitivity analyses explored heterogeneity in effect sizes. We identified 61 studies (53 datasets) assessing interference control in 1873 ATS users and 1905 controls. Findings revealed robust small effect sizes for ATS-related deficits in interference control, which were mainly seen in methamphetamine, as compared to MDMA users. The differential effects are likely due to tolerance-induced dopaminergic deficiencies (presumably most pronounced in methamphetamine users). Similarities between different ATS could be due to noradrenergic deficiencies; but elucidating their functional role in ATS users requires further/more research.

Abstract
Sensors developed from nanomaterials are increasingly used in a variety of fields, from simple wearable or medical sensors to be used at home to monitor health, to more complicated sensors being used by border customs or aviation industries. In recent times, nanoparticle-based sensors have begun to revolutionize drug-detection techniques, mainly due to their affordability, ease of use and portability, compared to conventional chromatography techniques. Thin graphene layers provide a significantly high surface to weight ratio compared to other nanomaterials, a characteristic that has led to the design of more sensitive and reliable sensors. The exceptional properties of graphene coupled with its potential to be tuned to target specific molecules have made graphene-based sensors one of the most popular and well-researched sensing materials of the past two decades with applications in environmental monitoring, medical diagnostics, and industries. Here, we present a review of developments in the applications of graphene-based sensors in sensing drugs such as cocaine, morphine, methamphetamine, ketamine, tramadol and so forth in the past decade. We compare graphene sensors with other sensors developed from ultrathin two-dimensional materials, such as transition-metal dichalcogenides, hexagonal boron nitrate, and MXenes, to measure drugs directly and indirectly, in various samples.

Abstract
BACKGROUND AND AIMS Drug checking services provide people who use drugs with chemical analysis results of their drug samples while simultaneously monitoring the unregulated drug market. We sought to identify and synthesize literature on the following domains: (a) the influence of drug checking services on the behaviour of people who use drugs; (b) monitoring of drug markets by drug checking services; and (c) outcomes related to models of drug checking services. METHODS Systematic review. A systematic literature search was conducted in MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, PsycINFO, Scopus, Web of Science and Dissertations and Theses Global. Eligible studies were peer-reviewed articles and conference abstracts or grey literature, published in any language since 1990 and including original data on the domains. We assessed risk of bias for quantitative peer-reviewed articles reporting on behaviour or models of drug checking services using National Institutes of Health tools. RESULTS We screened 2463 titles and abstracts and 156 full texts, with 90 studies meeting inclusion criteria. Most (n = 65, 72.2%) were from Europe and used cross-sectional designs (n = 79, 87.7%). Monitoring of drug markets by drug checking services (n = 63, 70%) was the most reported domain, followed by the influence of drug checking services on behaviour (n = 31, 34.4%), including intent to use, actual use and disposal of the drug, and outcomes related to models of drug checking services (n = 17, 18.9%). The most common outcome measures were detection of unexpected substances (n = 50, 55.6%), expected substances (n = 44, 48.9%), new psychoactive substances (n = 40, 44.4%) and drugs of concern (n = 32, 36.5%) by drug checking services. CONCLUSIONS Drug checking services appear to influence behavioural intentions and the behaviour of people who use drugs, particularly when results from drug checking services are unexpected or drugs of concern. Monitoring of drug markets by drug checking services is well established in Europe, and increasingly in North America. Concerns about drug contents and negative health consequences facilitate the use of drug checking services; lack of concern; trust in drug sellers; lack of accessibility of drug checking services; and legal and privacy concerns are barriers to use.

Abstract
Polysubstance use makes up a majority of drug use, yet relatively few studies investigate the abuse-related effects of drug mixtures. Dose-addition analyses provide a rigorous and quantitative method to determine the nature of the interaction (i.e., supraadditive, additive, or subadditive) between two or more drugs. As briefly reviewed here, studies in rhesus monkeys have applied dose-addition analyses to group level data to characterize the nature of the interaction between the reinforcing effects of stimulants and opioids (e.g., mixtures of cocaine + heroin). Building upon these foundational studies, more recent work has applied dose-addition analyses to better understand the nature of the interaction between caffeine and illicit stimulants such as MDPV and methamphetamine in rats. In addition to utilizing a variety of operant procedures, including drug discrimination, drug self-administration, and drug-primed reinstatement, these studies have incorporated potency and effectiveness ratios as a method for both statistical analysis and visualization of departures from additivity at both the group and individual subject level. As such, dose-addition analyses represent a powerful and underutilized approach to quantify the nature of drug-drug interactions that can be applied to a variety of abuse-related endpoints in order to better understand the behavioral pharmacology of polysubstance use.

Impact of co-ingestion of ethanol on the clinical symptomatology and severity of patients attended in the emergency department for recreational drug toxicity. Am J Emerg Med 2021; 50:422-427. [PMID: 34482128 DOI: 10.1016/j.ajem.2021.08.046] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Revised: 08/16/2021] [Accepted: 08/18/2021] [Indexed: 11/27/2022] Open
Abstract
OBJECTIVE Investigate whether there are differences in the drugs involved, symptomatology and severity of drug intoxication in patients with co-ingestion of alcohol attended in hospital emergency departments (ED). METHOD Patients attended in 11 Spanish EDs due to drug intoxication were included. Sociodemographic and clinical characteristics were collected. A combined adverse event of cardiorespiratory arrest, need for intubation, and admission to intensive care or death was considered as the primary indicator of severity. The symptomatology and severity were compared adjusted for age, sex and type of drug based on whether or not ethanol had been co-ingested. RESULTS 3925 patients (alcohol co-ingestion: 2290, 58.3%) with a mean age of 33 (±11) years were included, and 25% were women. Co-ingestion of alcohol was observed in younger patients, in EDs in areas with high leisure tourism, on holidays and during the early morning hours. It was also more frequent in individuals intoxicated by amphetamine derivatives (66.2%) and cocaine (65.7%), and was more frequently associated with a reduction in consciousness (odds ratio [OR] = 2.13, 95% confidence interval [CI] 1.69-2.67) and agitation/aggressiveness (OR = 1.22, 95% = 1.04-1.43). A combined adverse event was observed in 114 patients (2.9%) with no differences between individuals co-ingesting or not ethanol (3.1% vs. 2.7%; OR = 1.11, 95% CI = 0.74-1.65). CONCLUSION Co-ingestion of alcohol is more frequent in individuals intoxicated by cocaine and amphetamines and predisposes a greater reduction in the level of consciousness or agitation, although there are no differences in the severity of the episodes of drug intoxication.

Abstract
OBJECTIVES Drug checking as a tool for harm reduction is offered in certain cities throughout Europe, the USA, and Australia, but in general, it is internationally still scarcely available and controversially discussed. This study aimed at investigating the potential impact of a drug-checking offer on Berlin nightlife attendees' illicit drug use and at identifying the encouraging and discouraging factors for using or refraining from such an offer. METHODS Using an online questionnaire, we conducted a cross-sectional survey in a Berlin party scene. A total of 719 people participated in the survey that took part in 2019. RESULTS The vast majority of participants (92%) stated that they would use drug checking, if existent. If the test revealed the sample to contain a high amount of active ingredient, 91% indicated to take less of the substance than usual. Two-thirds (66%) would discharge the sample if it contained an unexpected/unwanted agent along with the intended substance. If the sample contained only unexpected/unwanted substances and not the intended substance at all, 93% stated to discharge the sample. Additional brief counseling was stated to be useful. Participants showed a comparatively high substance use. CONCLUSIONS Drug checking as a harm reduction tool was highly accepted in the scene, and the majority of participants stated to align their consumption behavior accordingly, in a reasonable manner. A concomitant consultation would be appreciated, which may be used to direct educational information about harms and risks to users.

Abstract
Drug checking is a service for people who use drugs that includes product analysis and an individual interview including results feedback and harm reduction counselling. It uses different analytical methods but few studies demonstrate their value in current practice. The main objective of this work is to compare the analytical performance of IR spectroscopy to laboratory reference method in the context of drug checking in a harm reduction centre. The secondary objectives are to carry out a description of the people who use drugs requesting a product analysis, and to compare the assumed compositions of products purchased with their real compositions. During 2018, all requests for drug testing analysis were included for on-site analysis by IR spectrometry in a harm reduction center and verified by the reference method (UPLC-HRMS) at Bordeaux University Hospital Center. Socioeconomic and product data were also collected. One hundred and thirty-six samples were collected. The results obtained with IR and UPLC-HRMS were compared. IR spectrometry results did not match with reference method in 8 % (n=11) of cases, corresponding to blotters, cannabis and some psychoactive substances present in mixture or in small quantities. Among the products collected, only 5.1 % (n=7) did not correspond to the declared product, either alone or with adulterants. The IR spectrometer allows a simple and rapid detection of at least one molecule, most often the one of interest. However, it is limited to powder and tablet type matrices and is not suitable for blotters, cannabis, mixed or low content substances for which high resolution mass spectrometry remains the reference method.

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
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
BACKGROUND The increasing incidence of fatal opioid overdose is a public health crisis in Canada. Given growing consensus that this crisis is related to the presence of highly potent opioid adulterants (e.g., fentanyl) in the unregulated drug supply, drug checking services (DCS) have emerged as part of a comprehensive approach to overdose prevention. In Canada's largest city, Toronto, a network of DCS launched in 2019 to prevent overdose and overdose-related risk behaviors. This network employs mass spectrometry technologies, with intake sites co-located with supervised consumption services (SCS) at three frontline harm reduction agencies. The protocol and rationale for assessing the impact of this multi-site DCS network in Toronto is described herein. The aims of this study are to (1) evaluate the impact of DCS access on changes in and factors influencing overdose and related risk behaviors, (2) investigate the perceived capacity of DCS to prevent overdose, and (3) identify composition (qualitative and quantitative) trends in Toronto's unregulated drug supply. METHODS We will use a parallel-mixed-methods design with complementary data sources (including data from chemical analysis of drug samples, quantitative intake and post-test surveys, SCS, coroners, paramedic services, and qualitative interviews), followed by a meta-inference process wherein results from analyses are synthesized. RESULTS Whereas most DCS globally target "recreational drug users," in Toronto, this networked DCS will primarily target marginalized people who use drugs accessing frontline services, many of whom use drugs regularly and by injection. This evolution in the application of DCS poses important questions that have not yet been explored, including optimal service delivery models and technologies, as well as unique barriers for this population. Increasing information on the unregulated drug supply may modify the risk environment for this population of people who use drugs. CONCLUSIONS This study addresses evidence gaps on the emerging continuum of overdose prevention responses and will generate critical evidence on a novel approach to reducing the ongoing high incidence of drug-related morbidity and mortality in Canada and elsewhere.

Abstract
±3,4-Methylenedioxymethamphetamine (MDMA) is a synthetic, psychoactive drug that is primarily used recreationally but also may have some therapeutic value. At low doses, MDMA produces feelings of relaxation, empathy, emotional closeness, and euphoria. Higher doses can produce unpleasant psychostimulant- and hallucinogen-like adverse effects and therefore are usually not taken intentionally. There is considerable evidence that MDMA produces neurotoxicity and cognitive deficits at high doses; however, these findings may not generalize to typical recreational or therapeutic use of low-dose MDMA. Here, we systematically review 25 years of research on the cognitive effects of MDMA in animals, with a critical focus on dose. We found no evidence that doses of less than 3 mg/kg MDMA-the dose range that users typically take-produce cognitive deficits in animals. Doses of 3 mg/kg or greater, which were administered most often and frequently ranged from 5 to 20 times greater than an average dose, also did not produce cognitive deficits in a slight majority of experiments. Overall, the preclinical evidence of MDMA-induced cognitive deficits is weak and, if anything, may be the result of unrealistically high dosing. While factors associated with recreational use such as polydrug use, adulterants, hyperthermia, and hyponatremia can increase the potential for neurotoxicity, the short-term, infrequent, therapeutic use of ultra low-dose MDMA is unlikely to pose significant cognitive risks. Future studies must examine any adverse cognitive effects of MDMA using clinically relevant doses to reliably assess its potential as a psychotherapeutic.

Abstract
BACKGROUND Impurities in commonly used illicit drugs raise concerns for unwitting consumers when pharmacologically active adulterants, especially new psychoactive substances (NPS), are used. This study examines impurities detected in illicit drugs seized in one Australian jurisdiction. METHODS Queensland Health Forensic and Scientific Services provided analytical data. Data described the chemical composition of 9346 samples of 11 illicit drugs seized by police during 2015-2016. Impurities present in primary drugs were summarized and tabulated. A systematic search for published evidence reporting similar analyses was conducted. RESULTS Methamphetamine was the primary drug in 6608 samples, followed by MDMA (1232 samples) and cocaine (516 samples). Purity of primary drugs ranged from ∼30% for cocaine, 2-CB and GHB to >90% for THC, methamphetamine, heroin and MDMA. Methamphetamine and MDMA contained the largest variety of impurities: 22 and 18 variants, respectively. Drug adulteration patterns were broadly similar to those found elsewhere, including NPS, but in some primary drugs impurities were found which had not been reported elsewhere. Psychostimulants were adulterated with each other. Levamisole was a common impurity in cocaine. Psychedelics were adulterated with methamphetamine and NPS. Opioids were quite pure, but some samples contained methamphetamine and synthetic opioids. CONCLUSIONS Impurities detected were mostly pharmacologically active adulterants probably added to enhance desired effects or for active bulking. Given the designer nature of these drug cocktails, the effects of the adulterated drugs on users from possible complex multi-drug interactions is unpredictable. Awareness-raising among users, research into complex multi-drug effects and ongoing monitoring is required.

Abstract
Objectives: The content of substances sold and consumed as party drugs is often unknown. They may contain inactive, contaminated or unexpected ingredients, and the dosage of the active components may vary considerably. Obviously, these phenomena increase the chances of a wrong or delayed therapy. To illustrate this point, we report 3 cases of clozapine intoxication at a dance event where most likely clozapine tablets were sold as party drugs.Methods: The three cases were part of a prospective toxicology study at a nocturnal indoor dance event.Results: One patient had to be intubated after obstructive breathing with desaturation and bradycardia, while the 2 other patients presented with syncope and altered mental status. All patients recovered after 20 minutes to 8 hours. Systematic toxicological analysis of the blood samples revealed the presence of clozapine (73-244 ng/ml) and its metabolite norclozapine (9-59 ng/ml). A pill, found in a pocket of one patient, was identified as Leponex® 100 mg (clozapine). This neuroleptic drug is mainly prescribed for treatment-resistant schizophrenia. In clozapine-naive subjects, orthostatic hypotension, bradycardia and syncope have been reported with a single 25 mg oral dose. Serum clozapine concentrations of the 3 cases were below the defined therapeutic range (350-600ng/ml) and the clozapine:norclozapine ratios were suggestive for recent drug intake.Conclusion: Routine drug screening may be unable to detect the toxic agent(s) involved. Whenever unusual symptoms are observed in an intoxicated patient, blood and urine samples should be sent to a reference toxicology laboratory.

Variability in content and dissolution profiles of MDMA tablets collected in the UK between 2001 and 2018 - A potential risk to users? Drug Test Anal 2019; 11:1172-1182. [PMID: 31009168 DOI: 10.1002/dta.2605] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2018] [Revised: 04/10/2019] [Accepted: 04/15/2019] [Indexed: 11/07/2022]
Abstract
3,4-Methylenedioxymethamphetamine (MDMA, Ecstasy) tablets are widely used recreationally, and not only vary in appearance, but also in MDMA content. Recently, the prevalence of high-content tablets is of concern to public health authorities. To compare UK data with other countries, we evaluated MDMA content of 412 tablets collected from the UK, 2001-2018, and investigated within-batch content variability for a sub-set of these samples. In addition, we investigated dissolution profiles of tablets using pharmaceutical industry-standard dissolution experiments on 247 tablets. All analyses were carried out using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Our data supported other studies, in that recent samples (2016-2018) tend to have higher MDMA content compared to earlier years. In 2018, the median MDMA content exceeded 100 mg free-base for the first time. Dramatic within-batch content variability (up to 136 mg difference) was also demonstrated. Statistical evaluation of dissolution profiles at 15-minutes allowed tablets to be categorized as fast-, intermediate-, or slow-releasing, but no tablet characteristics correlated with dissolution classification. Hence, there would be no way of users knowing a priori whether a tablet is more likely to be fast or slow-releasing. Further, within-batch variation in dissolution rate was observed. Rapid assessment of MDMA content alone provides important data for harm reduction, but does not account for variability in (a) the remainder of tablets in a batch, or (b) MDMA dissolution profiles. Clinical manifestations of MDMA toxicity, especially for high-content, slow-releasing tablets, may be delayed or prolonged, and there is a significant risk of users re-dosing if absorption is delayed.

Behavioral economic analysis of the reinforcing effects of "bath salts" mixtures: studies with MDPV, methylone, and caffeine in male Sprague-Dawley rats. Psychopharmacology (Berl) 2019; 236:1031-1041. [PMID: 30267131 PMCID: PMC6440875 DOI: 10.1007/s00213-018-5046-x] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/19/2018] [Accepted: 09/19/2018] [Indexed: 10/28/2022]
Abstract
RATIONALE "Bath salts" preparations often contain combinations of synthetic cathinones (e.g., 3,4-methylenedioxymethcathinone [methylone], 3,4-methylenedioxypyrovalerone [MDPV]), and caffeine, and evidence suggests that mixtures of synthetic cathinones and caffeine (e.g., MDPV + caffeine or methylone + caffeine) can be more potent and/or effective reinforcers than predicted for an additive interaction. OBJECTIVE To use demand curve analyses to compare the reinforcing effectiveness of MDPV and methylone to mixtures of MDPV + caffeine and methylone + caffeine. METHODS Male Sprague-Dawley rats acquired methylone self-administration (0.32 mg/kg/inf) under a fixed ratio (FR) 1 schedule of reinforcement and generated full dose-response curves for methylone (0.01-1 mg/kg/inf) under an FR5 schedule of reinforcement. Demand curves were then obtained for methylone, MDPV, caffeine, and methylone + caffeine and MDPV + caffeine mixtures by increasing the FR across sessions according to the following series: 3, 10, 18, 32, 56, 100, 178, etc. RESULTS: Self-administration of methylone was rapidly acquired by 87.5% of rats and was maintained across a range of doses, producing an inverted U-shaped dose-response curve. Rank order demand for the individual constituents was MDPV > methylone > caffeine. Demand for the 3:1 (but not 10:1) methylone + caffeine mixture was greater than that for methylone alone, and demand for MDPV alone was similar to both MDPV + caffeine mixtures evaluated. CONCLUSIONS These studies provide additional evidence that although methylone is an effective reinforcer, combining methylone with caffeine results in an enhanced reinforcing effectiveness compared to methylone alone. Thus, abused "bath salts" preparations containing synthetic cathinones and caffeine may have higher abuse liability than preparations containing only synthetic cathinones.

Abstract
INTRODUCTION AND AIMS Ecstasy users in the electronic dance music scene are at high risk for using ecstasy adulterated with new psychoactive substances and/or methamphetamine. We examined self-reported testing of ecstasy among users in this scene. DESIGN AND METHODS We surveyed individuals (aged 18-40 years) entering electronic dance music parties in New York City in 2017. Past-year ecstasy users (n = 351) were asked if they had tested their ecstasy in the past year. We estimated prevalence and correlates of having tested one's ecstasy. RESULTS 23.1% reported having tested their ecstasy in the past year. Those with some college (adjusted prevalence ratio [aPR] = 0.49, P = 0.014) or a college degree (aPR = 0.41, P = 0.025) were less likely to test their ecstasy than those with a high school diploma or less. Using ecstasy pills (aPR = 1.89, P = 0.036) or crystals (aPR = 1.90, P = 0.006) ≥3 times in the past year was associated with increased likelihood of testing one's ecstasy, and purchasing from an unknown or untrustworthy dealer was associated with decreased likelihood (aPR = 0.63, P = 0.034) of testing one's ecstasy. Half (51.1%) of ecstasy users reported finding out or suspecting their ecstasy had contained a drug other than MDMA. Of these, 49.2% reported finding out their ecstasy contained methamphetamine or speed/amphetamine. Most ecstasy users reported that they would be less likely to use again upon learning their ecstasy contained 'bath salts' (54.8%) or methamphetamine (54.3%). DISCUSSION AND CONCLUSIONS Drug testing appears to help ecstasy users detect adulterants and results can help inform harm reduction efforts. Less frequent users in particular may require education about adulteration and drug-testing.

Abstract
The number of emerging novel stimulants modified based on beta-keto variations of amphetamine-like substances continues to rise. Dibutylone reports described in the medical and toxicological literature are limited, therefore little information is available in terms of quantitative confirmation or metabolism. During this study, authentic human specimens, including blood, urine, vitreous humor, oral fluid and liver were quantitatively and qualitatively analyzed for the presence of dibutylone and butylone, with paired case history and demographic information. Dibutylone concentrations were variable across all specimen types, specifically ranging from 10 to 1,400 ng/mL in postmortem blood specimens. The metabolic profile of dibutylone was mapped by in vitro incubation with human liver microsomes (HLM). Samples were analyzed using a SCIEX TripleTOF® 5600+ quadrupole time-of-flight mass spectrometer. Data processing was conducted using MetabolitePilot™. Authentic human specimens, including blood, urine, vitreous humor, oral fluid and liver, were utilized for in vivo verification of five HLM-generated metabolites in analytically confirmed cases of dibutylone use. Butylone was confirmed as a metabolite of dibutylone, but issues involving co-ingestion of these two novel stimulants or potential co-existence from synthesis lead to ineffectiveness as a true biomarker. Hydrogenation of the beta-ketone of dibutylone resulted in the most prominent metabolite found in human specimens, and its uniqueness to dibutylone over other stimulants leads to its classification as an appropriate biomarker for dibutylone ingestion. This is the first study to map the metabolic profile of dibutylone, including verification in authentic specimens, confirming metabolic conversion to butylone and identifying biomarkers more useful in forensic toxicological drug testing.

Abstract
Background: Nondisclosure of drug use on surveys is common, and many drug users unknowingly ingest adulterant or replacement drugs, which leads to underreporting of use of these drugs. Biological testing can complement survey research, and hair testing is an appealing method, as many drugs are detectable for months post-use. We examined willingness to donate a hair sample to be tested among those surveyed in a population at high risk for consuming adulterated drugs-electronic dance music (EDM) party attendees. Methods: We surveyed 933 adults entering EDM parties in New York City in 2017. Hair donation response rates and reasons for refusal were examined from this cross-sectional study. Results: A third (n = 312; 33.4%) provided a hair sample. Lack of interest (21.0%), lack of time (19.8%), not wanting a lock of hair cut (17.7%), and disinterest in having hair cut in public (13.8%) were the main reported reasons for refusal; 4.7% refused because they could not receive results. Past-year drug users were more likely to fear identification than nonusers (P < .001). Asian participants were at lower odds of providing a hair sample (adjusted odds ratio [aOR] = 0.53, 95% confidence interval [CI] = 0.32-0.87), and those reporting past-year use of LSD (aOR = 1.62, 95% CI = 1.11-2.35), opioids (nonmedical; aOR = 1.93, 95% CI = 1.25-2.99), and/or methamphetamine (aOR = 3.43, 95% CI = 1.36-8.62) were at higher odds of providing a sample than nonusers of these drugs. Conclusions: Only a third of participants provided a hair sample, and we found individual-level differences regarding willingness to provide a sample. Factors contributing to refusal should be considered to increase response rates and generalizability of results.

Abstract
BACKGROUND Neuroimaging studies imply that the regular use of ±3,4-methylenedioxymethamphetamine (MDMA), the major constituent of ecstasy pills, alters the brain's serotonergic system in a dose-dependent manner. However, the relevance of these findings remains unclear due to limited knowledge about the ecstasy/MDMA use pattern of real-life users. AIMS We examined the representativeness of ecstasy users enrolled in neuroimaging studies by comparing their ecstasy use habits with the use patterns of a large, international sample. METHODS A systematic literature search revealed 10 imaging studies that compare serotonin transporter levels in recreational ecstasy users to matched controls. To characterize the ecstasy use patterns we relied on the Global Drug Survey, the world's largest self-report database on drug use. The basis of the dose comparison were the Usual Amount (pills/session), Use Frequency (sessions/month) and Dose Intensity (pills/year) variables. RESULTS Both the average Usual Amount (pills/session) and Use Frequency (sessions/month) of neuroimaging study participants corresponded to the top 5-10% of the Global Drug Survey sample and imaging participants, on average, consumed 720% more pills over a year than the Global Drug Survey participants. CONCLUSIONS Our findings suggest that the serotonin brain imaging literature has focused on unusually heavy ecstasy use and therefore the conclusions from these studies are likely to overestimate the extent of serotonergic alterations experienced by the majority of people who use ecstays.

Abstract
Bath salts use is associated with high rates of abuse, toxicity, and death. Bath salt preparations often contain mixtures of drugs including multiple synthetic cathinones (eg, 3,4-methylenedioxypyrovalerone (MDPV) or 3,4-methylenedioxymethcathinone (methylone)) or synthetic cathinones and caffeine; however, little is known about whether interactions among bath salt constituents contribute to the abuse-related effects of bath salts preparations. This study used male Sprague-Dawley rats responding under a progressive ratio schedule to quantify the reinforcing effectiveness of MDPV, methylone, and caffeine, administered alone and as binary mixtures (n=12 per mixture). Each mixture was evaluated at four ratios (10 : 1, 3 : 1, 1 : 1, and 1 : 3) relative to the mean ED50 for each drug alone. Dose-addition analyses were used to determine the predicted, additive effect for each dose pair within each drug mixture. MDPV, methylone, and caffeine maintained responding in a dose-dependent manner, with MDPV being the most potent and effective, and caffeine being the least potent and effective of the three bath salts constituents. High levels of responding were also maintained by each of the bath salts mixtures. Although the nature of the interactions tended toward additivity for most bath salts mixtures, supra-additive (3 : 1 MDPV : caffeine, and 3 : 1 and 1 : 1 methylone : caffeine) and sub-additive (3 : 1, 1 : 1, and 1 : 3 MDPV : methylone) interactions were also observed. Together, these findings demonstrate that the composition of bath salts preparations can have an impact on both their reinforcing potency and effectiveness, and suggest that such interactions among constituent drugs could contribute to the patterns of use and effects reported by human bath salts users.

Abstract
BACKGROUND Amphetamine is the most prevalent prescription stimulant in the United States, both medically and nonmedically. Reliable data on nonmedical use is needed to continue to inform prevention. To determine whether adolescents accurately self-report nonmedical amphetamine use, we compared self-reports of nonmedical amphetamine use and nonmedical Adderall use in a national sample. METHODS We examined self-reported nonmedical Adderall and amphetamine use in a nationally representative sample of 24,740 high school seniors in the Monitoring the Future study (2010-2015). We examined prevalence and correlates of discordant responses among past-year Adderall users, defined as reporting past-year nonmedical Adderall use, but not reporting past-year nonmedical amphetamine use. RESULTS While 6.9% reported nonmedical Adderall use and 7.9% reported nonmedical amphetamine use, over a quarter (28.7%) of Adderall users reported no amphetamine use. Those at highest risk for Adderall use tended to be at lower odds of providing a discordant response. Older students (aged ≥18), black students, and those with parents of lower educational attainment were more likely to report no amphetamine use, despite reporting Adderall use. Lifetime use of various drugs was associated with decreased odds of providing a discordant response; however, only nonmedical opioid use was associated with significant decreased odds in multivariable models. Disapproval towards amphetamine use increased odds of providing a discordant response, while higher exposure to users decreased odds of providing a discordant response. CONCLUSION Prevalence of nonmedical amphetamine use may be underreported on some surveys, particularly among specific subpopulations. Future surveys must ensure accurate and consistent responses.

Abstract
Ecstasy (MDMA) has regained popularity in powder and crystalline form, known as Molly. However, it is unknown whether all Molly users are aware that Molly is ecstasy. A total of 1045 nightclub/festival-attending adults in New York City were surveyed about ecstasy/MDMA/Molly use in 2016. Users were asked if they agreed that "Molly is (or is supposed to be) ecstasy/MDMA." Of the 43.5% reporting lifetime use, 84.6% agreed that Molly is ecstasy, 9.5% disagreed, and 5.9% reported not knowing that Molly is ecstasy. Prevalence of use of other drugs (e.g., ketamine, opioids, methamphetamine, NBOMe, 2C series) was lowest among those not knowing that Molly is ecstasy, and highest among those not agreeing that Molly is ecstasy. Those not knowing that Molly is ecstasy were less likely to have used powder or crystal MDMA and less likely to have used in the past 12 months or to report intention to use again. Those disagreeing or not knowing that Molly is ecstasy were at over six times the odds of obtaining ecstasy from an unknown dealer, and those disagreeing were at four times higher odds of having suspected or found out that their ecstasy was adulterated. Results suggest that knowing or agreeing that Molly is ecstasy/MDMA can help indicate ecstasy-related risk.

[PMID: 28869878 DOI: 10.1016/j.drugpo.2017.07.030] [Citation(s) in RCA: 42] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2016] [Revised: 07/18/2017] [Accepted: 07/26/2017] [Indexed: 12/29/2022]
Abstract
BACKGROUND Ecstasy pills with MDMA as the main ingredient were introduced in many European countries in the 1980s, and were often linked to the rave and club scenes. However, use gradually levelled off, in part as a response to increased concerns about possible mental health consequences and fatalities. Extensive use of MDMA now seems to be re-emerging in many countries. In this study, we investigated the cultural and social meaning associated with MDMA use in Oslo, Norway, with an emphasis on how users distinguish MDMA crystals and powder from "old ecstasy pills". METHODS Qualitative in-depth interviews (n=31, 61,3% males) were conducted with young adult party-goers and recreational MDMA/ecstasy users (20-34 years old, mean age 26.2 years). RESULTS Research participants emphasised three important perceived differences between the MDMA crystals and ecstasy pills: (i) The effects of MDMA were described as better than ecstasy; (ii) MDMA was regarded as a safer drug; (iii) Users of MDMA crystals were described as more distinct from and less anchored in out-of-fashion rave culture than those using ecstasy. These differences were an important part of the symbolic boundary work MDMA users engaged in when justifying their drug use. CONCLUSION MDMA has re-emerged as an important psychoactive substance in Oslo's club scene. One important reason for this re-emergence seems to be its perceived differentiation from ecstasy pills, even though the active ingredient in both drugs is MDMA. This perceived distinction between MDMA and ecstasy reveals the importance of social and symbolic meanings in relation to psychoactive substance use. Insights from this study can be important in terms of understanding how trends in drug use develop and how certain drugs gain or lose popularity.

Abstract
BACKGROUND Data on both known and unknown drug use in the electronic dance music (EDM) scene is important to inform prevention and harm reduction. While surveys are the most common method of querying drug use, additional biological data can help validate use and detect unknown/unintentional use of drugs such as new psychoactive substances (NPS). We sought to determine the extent of both known and unknown use of various substances in this high-risk scene. METHODS We hair-tested 90 self-reported past-year ecstasy/MDMA/Molly users attending EDM parties in New York City during the summer of 2016 using UHPLC-MS/MS. Results were compared to self-reported past-year use. RESULTS Three quarters (74.4%) tested positive for MDMA, a third (33.3%) tested positive for an NPS, and 27.8% tested positive specifically for one or more synthetic cathinones (e.g., butylone, ethylone, pentylone, methylone, alpha-PVP). Half (51.1%) of participants tested positive for a drug not self-reported, with most testing positive for synthetic cathinones (72.0%), methamphetamine (69.0%), other NPS stimulants (e.g., 4-FA, 5/6-APB; 66.7%), or new dissociatives (e.g., methoxetamine, diphenidine; 60.0%). Attending parties every other week or more often, reporting higher-frequency ecstasy pill use, having tested one's ecstasy, and having found out one's ecstasy was adulterated, were risk factors for testing positive for synthetic cathinones and NPS in general. CONCLUSION Hair testing appears to be a valuable addition to drug epidemiology studies. Many EDM party attendees-even those who test their ecstasy-are unknowingly using NPS and/or other drugs. Prevention information and harm reduction may help reduce unknown/unintentional use.

Abstract
INTRODUCTION AND AIMS This study aimed to determine design features of a drug-checking service that would be feasible, attractive and likely to be used by Australian festival and nightlife attendees. DESIGN AND METHODS Web survey of 851 Australians reporting use of psychostimulants and/or hallucinogens and attendance at licensed venues past midnight and/or festivals in the past year (70% male; median age 23 years). RESULTS A drug-checking service located at festivals or clubs would be used by 94%; a fixed-site service external to such events by 85%. Most (80%) were willing to wait an hour for their result. Almost all (94%) would not use a service if there was a possibility of arrest, and a majority (64%) would not use a service that did not provide individual feedback of results. Drug-checking results were only slightly more attractive if they provided comprehensive quantitative results compared with qualitative results of key ingredients. Most (93%) were willing to pay up to $5, and 68% up to $10, per test. One-third (33%) reported willingness to donate a whole dose for testing: they were more likely to be male, younger, less experienced, use drugs more frequently and attend venues/festivals less frequently. DISCUSSION AND CONCLUSIONS In this sample, festival- or club-based drug-checking services with low wait times and low cost appear broadly attractive under conditions of legal amnesty and individualised feedback. Quantitative analysis of ecstasy pills requiring surrender of a whole pill may appeal to a minority in Australia where pills are more expensive than elsewhere.

Abstract
Hundreds of new psychoactive substances (NPS) have emerged in the drug market over the last decade. Few drug surveys in the USA, however, ask about use of NPS, so prevalence and correlates of use are largely unknown. A large portion of NPS use is unintentional or unknown as NPS are common adulterants in drugs like ecstasy/Molly, and most NPS are rapidly eliminated from the body, limiting efficacy of urine, blood and saliva testing. We utilized a novel method of examining prevalence of NPS use in a high-risk population utilizing hair-testing. Hair samples from high-risk nightclub and dance music attendees were tested for 82 drugs and metabolites (including NPS) using ultra-high performance liquid chromatography-tandem mass spectrometry. Eighty samples collected from different parts of the body were analyzed, 57 of which detected positive for at least one substance-either a traditional or new drug. Among these, 26 samples tested positive for at least one NPS-the most common being butylone (25 samples). Other new drugs detected include methylone, methoxetamine, 5/6-APB, α-PVP and 4-FA. Hair analysis proved a powerful tool to gain objective biological drug-prevalence information, free from possible biases of unintentional or unknown intake and untruthful reporting of use. Such testing can be used actively or retrospectively to validate survey responses and inform research on consumption patterns, including intentional and unknown use, polydrug-use, occasional NPS intake and frequent or heavy use.

Abstract
BACKGROUND New psychoactive substances (NPS) continue to emerge; however, few surveys of substance use ask about NPS use. Research is needed to determine how to most effectively query use of NPS and other uncommon drugs. OBJECTIVE To determine whether prevalence of self-reported lifetime and past-year use differs depending on whether or not queries about NPS use are preceded by "gate questions." Gate questions utilize skip-logic, such that only a "yes" response to the use of specific drug class is followed by more extensive queries of drug use in that drug class. METHODS We surveyed 1,048 nightclub and dance festival attendees (42.6% female) entering randomly selected venues in New York City in 2016. Participants were randomized to gate vs. no gate question before each drug category. Analyses focus on eight categories classifying 145 compounds: NBOMe, 2C, DOx, "bath salts" (synthetic cathinones), other stimulants, tryptamines, dissociatives, and non-phenethylamine psychedelics. Participants, however, were asked about specific "bath salts" regardless of their response to the gate question to test reliability. We examined whether prevalence of use of each category differed by gate condition and whether gate effects were moderated by participant demographics. RESULTS Prevalence of use of DOx, other stimulants, and non-phenethylamine psychedelics was higher without a gate question. Gate effects for other stimulants and non-phenethylamine psychedelics were larger among white participants and those attending parties less frequently. Almost one in ten (9.3%) participants reporting no "bath salt" use via the gate question later reported use of a "bath salt" such as mephedrone, methedrone, or methylone. CONCLUSION Omitting gate questions may improve accuracy of data collected via self-report.

Abstract
Molly has been the street name for powder or crystalline ecstasy (3,4-methylenedioxymethamphetamine [MDMA]) in the United States since the early 2000s; however, few studies have examined Molly use or included Molly in the definition of ecstasy/MDMA. Prevalence of self-reported ecstasy use is being underreported on surveys due to the lack of inclusion of "Molly," although Molly is often so adulterated with novel psychoactive substances such as synthetic cathinones ("bath salts") that the name "Molly" may no longer adequately represent ecstasy/MDMA. The author recommends that Molly use and Molly purity be further studied to more adequately inform prevention and harm reduction.

Abstract
A solid sensor obtained by embedding 1,2-naphthoquinone-4-sulfonate (NQS) into polydimethylsiloxane/tetraethylortosilicate/silicon dioxide nanoparticles composite has been developed to identify and determine amphetamine (AMP), methamphetamine (MAMP), 3,4-methylenedioxymetamphetamine (MDMA) and 3,4-methylenedioxyamphetamine (MDA). The analytes are derivatized inside the composite for 10 min to create a colored product which can be then quantified by measuring the diffuse reflectance or the color intensity after processing the digitalized image. Satisfactory limits of detection (0.002-0.005 g mL-1) and relative standard deviations (<10%) have been achieved. The proposed kit has been successfully validated and applied to the analysis of amphetamine-like drugs street samples. The kit allows the in-situ screening of the mentioned illicit drugs owing to its simplicity, rapidity and portability, with excellent sensor stability and at a very low-cost.
