Prevalence and Correlates of Past Year Ecstasy/MDMA Use in the United States

OBJECTIVES

3,4-Methylenedioxymethamphetamine (MDMA) (also known as "ecstasy" or "Molly") has regained attention in recent years for its efficacy in treating posttraumatic stress disorder, and the drug was granted breakthrough therapy designation for such use by the US Food and Drug Administration in 2017. However, little is known about the current epidemiology of recreational ecstasy/MDMA use.

METHODS

We estimated past-year prevalence and correlates of ecstasy/MDMA use based on a representative sample of noninstitutionalized US individuals 12 years or older from the 2015-2020 National Survey on Drug Use and Health (N = 315,661).

RESULTS

An estimated 0.9% (95% confidence interval [CI] = 0.9-1.0) of individuals used ecstasy/MDMA in the past year. Compared with those ages 35-49 years, all younger age groups were at increased odds for use, while those older than 50 years (adjusted odds ratio [aOR] = 0.14, 95% CI = 0.08-0.23) were at low odds for use. Compared with heterosexual men, those identifying as bisexual women (aOR = 1.32, 95% CI = 1.02-1.72) were at increased odds for use, and compared with White individuals, those identifying as Asian (aOR = 1.92, 95% CI = 1.42-2.59), Black (aOR = 1.70, 95% CI = 1.41-2.06), or multiracial (aOR = 1.61, 95% CI = 1.19-2.16) were at increased odds for use. Past-year use of other drugs (e.g., cannabis, ketamine), prescription drug misuse (e.g., pain relievers, stimulants), nicotine dependence (aOR = 1.21, 95% CI = 1.00-1.45), and alcohol use disorder (aOR = 1.41, 95% CI = 1.25-1.58) were also associated with increased odds for use.

CONCLUSIONS

While use of ecstasy/MDMA continues to be relatively rare, findings from this study can help inform prevention and harm reduction strategies, especially among certain subpopulations that are at high risk for use.

Evaluating the sensitivity, stability, and cross-reactivity of commercial fentanyl immunoassay test strips

Illicit fentanyl has flooded the United States' drug market, increasing the risk of overdose and poisonings throughout the general population and accidental exposure among law enforcement officers confiscating the increasing number of seizures. Fentanyl test strips (FTS) are used to obtain presumptive information about the presence of fentanyl in a suspected sample. However, their adoption by law enforcement personnel and seized-drug analysts has been limited because most products are advertised for urine testing, not for assays using water solutions. This study presents an evaluation of four commercial FTS: Rapid Response from BTNX, Inc.; T-Dip Fentanyl (FTY) Urine Dip Cards obtained from Amazon.com; Premier BioDip FYL10 from Premier Biotech Inc.; and MobileDetect Fentanyl strips from DetectaChem, Inc. Performance characteristics curves were used to compare the products' sensitivity, showing that all can reliably detect fentanyl in aqueous solutions at concentrations below 1 μg/mL, with some of the tests able to reliably detect the drug at 200 ng/mL. A stability study demonstrates the performance of all four FTS brands was only slightly affected after 30 days of storage at two extreme environmental conditions. Fentanyl-related substances are also evaluated using the Rapid Response FTS, which showed high cross-reactivity with para-fluorofentanyl and acetylfentanyl, but lower with ortho-chlorofentanyl, carfentanil, and 4-ANPP. Users should be aware that FTS may give false-negative results even when potentially dangerous levels of carfentanil are present. When testing other common drugs, adulterants, and diluents frequently encountered in seized tablets, concentration-dependent results were obtained and multiple instances of false positives were recorded.

Virtual overdose monitoring services and overdose prevention technologies: Opportunities, limitations, and future directions

Overdose mortality has continued to rise in North America and across the globe in people who use drugs. Current harm reduction strategies such as supervised consumption sites and naloxone kit distribution have been important public health strategies implemented to decrease the harms associated with illicit drug use however have key limitations which prevent their scalability. This is represented in statistics which indicate that the vast majority of overdose mortality occur in individuals who use drugs by themselves. To address this, virtual overdose monitoring services and overdose detection technologies have emerged as an adjunct solution that may help improve access to harm reduction services for those that cannot or choose not to access current in-person services. This article outlines the current limitations of harm reduction services, the opportunities, challenges, and controversies of these technologies and services, and suggests avenues for additional research and policy development.

Phentermine involvement in fatal drug overdoses in Tennessee, 2019-2022

INTRODUCTION

Phentermine, one of the most-commonly prescribed pharmaceuticals for weight-loss in the United States (US), has appeared on toxicology and listed as a cause of death in fatal drug overdoses in the state of Tennessee. This study aims to evaluate phentermine's involvement in fatal drug overdoses in the state of Tennessee.

METHODS

We used Tennessee State Unintentional Drug Overdose Reporting System (SUDORS) data and controlled substances monitoring program data (CSMD) to evaluate demographics, prescription history and co-occurring substances on toxicology in phentermine-positive cases compared with all other SUDORS cases from January 1, 2019 to June 30, 2022. A subset of these cases which listed phentermine as a cause of death was also assessed.

RESULTS

We identified 51 phentermine-positive cases, with a subset of 20 that listed phentermine as a cause of death. When compared to all SUDORS cases, a higher proportion of cases that listed phentermine as a cause of death were White race, females, and aged 35-44. Additionally, in all phentermine-positive cases, 41% (21) of decedents had not had a phentermine prescription dating back to 2012 and 20% (Lee et al., 1998) did not have one within the last 30 days. While there was a slight decline each year in the number of phentermine-positive cases, the number of cases that listed phentermine as a cause of death remained relatively consistent, with 95% (19) of cases having different prescriptions and/or illicit drugs listed as a cause of death along with phentermine.

CONCLUSION

Phentermine was listed as a cause of death in 20 fatal drug overdoses in TN. Our findings suggest there may be differences in the characteristics of these decedents when compared to all SUDORS decedents, including distribution of age, gender, and race. We also found a large presence of other prescription and illicit drugs in toxicology and cause of death along with phentermine, as well as evidence of use of the drug without a prescription. Given the lack of currently available data about non-prescribed phentermine use and its involvement in fatal drug overdoses elsewhere, a need exists to both expand surveillance capabilities and broaden research to better inform policies governing this drug in the US and internationally.

"They sent it away for testing and it was all bunk": Exploring perspectives on drug checking among steroid consumers in Queensland, Australia

INTRODUCTION

Research supports the feasibility and acceptance of drug checking among nightlife and festival attendees. Interest in expanding drug checking to other groups of people who use drugs, including those who inject drugs, has grown. However, understanding the acceptability and feasibility of drug checking among specific cohorts, like anabolic-androgenic steroids (AAS) consumers, remains a research gap. This study explores AAS consumers' perspectives on drug checking and service preferences, aiding the preparation for drug checking delivery in Queensland, Australia.

METHODS

A purposive sampling technique was used to recruit 15 AAS consumers (9 males, 6 females; Mage = 36.80 years, SD = 6.12) from Australia. One-on-one semi-structured qualitative interviews were conducted with questions exploring participants' views on drug checking/testing and their preferences for AAS analysis. Thematic analysis was conducted with final themes established through iterative consensus.

RESULTS

Consumers expressed frustration with the prevailing stereotypes, social stigma, and the perception of criminality associated with the use of AAS. There was a strong dependence on personal connections and trusted suppliers, with coaches exerting significant influence. Participants expressed concerns about the widespread availability of counterfeit products and underground operations. The act of using unknown AAS was likened to a game of Russian roulette, underscoring the importance of obtaining accurate information and access to reliable drug checking services. Consumers expressed a preference for a web-based platform that enables individuals to access their own test results while contributing to a comprehensive database of brand-specific testing outcomes.

DISCUSSION

AAS consumers recognise the significance of monitoring their AAS use and seek a service that can not only assist them in making informed decisions regarding AAS usage but also potentially contribute to the knowledge of the wider AAS-consuming community. These findings underscore the importance of tailored education, drug checking services, and harm reduction measures to address the diverse needs of AAS consumers.

COVID-19 control accelerates the decline in illegal drug use in China

This work illustrates the accelerated decline in illegal drug use during the COVID-19 pandemic in China. We first reviewed the global effects of the COVID-19 pandemic on the situation of illegal drugs. We then compared the data of the pre-pandemic (2016-2019) and pandemic period (2020-2022) for drug seizures, individuals identified as using drugs, registered and newly discovered illegal drug users and the number of community-treated drug users to demonstrate the fast decline in the use of illegal drugs in China. We then discussed the possible reasons and additional considerations for these changes. Overall, the COVID-19 controls in China, such as all-staff nucleic acid testing and ID-based dynamic monitoring, substantially reduced illegal drug use. Being wary of a possible rebound in drug use and preventing new types of drug crimes are still essential in post-COVID China.

Attitudes and beliefs about Vermont's 2021 buprenorphine decriminalization law among residents who use illicit opioids

BACKGROUND

In July 2021, Vermont removed all criminal penalties for possessing 224mg or less of buprenorphine.

METHODS

Vermont residents (N=474) who used illicit opioid drugs or received treatment for opioid use disorder in the past 90 days were recruited for a mixed-methods survey on the health and criminal legal effects of decriminalization. Topics assessed included: motivations for using non-prescribed buprenorphine, awareness of and support for decriminalization, and criminal legal system experiences involving buprenorphine. We examined the frequencies of quantitative measures and qualitatively summarized themes from free-response questions.

RESULTS

Three-quarters of respondents (76%) reported lifetime use of non-prescribed buprenorphine. 80% supported decriminalization, but only 28% were aware buprenorphine was decriminalized in Vermont. Respondents described using non-prescribed buprenorphine to alleviate withdrawal symptoms and avoid use of other illicit drugs. 18% had been arrested while in buprenorphine, with non-White respondents significantly more likely to report such arrests (15% v 33%, p<0.001).

CONCLUSION

Decriminalization of buprenorphine may reduce unnecessary criminal legal system involvement, but its health impact was limited by low awareness at the time of our study.

Police seizure of drugs without arrest among people who use drugs in Vancouver, Canada, before provincial 'decriminalization' of simple possession: a cohort study

BACKGROUND

Several jurisdictions in Canada have recently considered decriminalizing possession of illicit drugs for personal use (henceforth, simple possession) as part of their responses to the ongoing drug toxicity/overdose crisis. In this context, we sought to examine an early implementation case of a de facto depenalization policy of simple possession offences in Vancouver, Canada, that was enacted in 2006. Specifically, we characterized experiences of people who use drugs (PWUD) whose drugs were discretionally seized by police without arrest.

METHODS

Data were derived from three prospective cohorts of community-recruited PWUD in Vancouver over 16 months in 2019-2021. We conducted multivariable generalized estimating equations analyses to determine the prevalence of and factors associated with drug seizure. Sub-analyses used data collected in 2009-2012 and examined the trends over time.

RESULTS

Among 995 participants who were interviewed in 2019-2021, 63 (6.3%) had their drugs seized by police at least once in the past 6 months. In multivariable analyses, factors significantly associated with drug seizure included: homelessness (adjusted odds ratio [AOR]: 1.98; 95% confidence interval [CI] 1.09-3.61), working in the unregulated drug market (AOR: 4.93; 95% CI 2.87-8.49), and naloxone administration (AOR: 2.15; 95% CI 1.23-3.76). In 2009-2012, 67.8% reported having obtained new drugs immediately after having their drugs seized by police. Odds of drug seizure were not significantly different between the two time periods (2019-2021 vs. 2009-2012) (AOR: 0.93; 95% CI: 0.64-1.35).

CONCLUSIONS

Despite the depenalization policy, the Vancouver Police Department has continued to seize illicit drugs from PWUD, even in cases where no arrest occurred. This policing practice may create health and safety risks for PWUD as it forces PWUD to increase the engagement with the unregulated illicit drug market. Our findings support calls for abolishing this often-undocumented discretionary policing practice that may exacerbate ongoing health inequities and interfere with peer-based overdose prevention efforts.

Molecular Docking Assessment of Cathinones as 5-HT2AR Ligands: Developing of Predictive Structure-Based Bioactive Conformations and Three-Dimensional Structure-Activity Relationships Models for Future Recognition of Abuse Drugs

Commercially available cathinones are drugs of long-term abuse drugs whose pharmacology is fairly well understood. While their psychedelic effects are associated with 5-HT2AR, the enclosed study summarizes efforts to shed light on the pharmacodynamic profiles, not yet known at the receptor level, using molecular docking and three-dimensional quantitative structure-activity relationship (3-D QSAR) studies. The bioactive conformations of cathinones were modeled by AutoDock Vina and were used to build structure-based (SB) 3-D QSAR models using the Open3DQSAR engine. Graphical inspection of the results led to the depiction of a 3-D structure analysis-activity relationship (SAR) scheme that could be used as a guideline for molecular determinants by which any untested cathinone molecule can be predicted as a potential 5-HT2AR binder prior to experimental evaluation. The obtained models, which showed a good agreement with the chemical properties of co-crystallized 5-HT2AR ligands, proved to be valuable for future virtual screening campaigns to recognize unused cathinones and similar compounds, such as 5-HT2AR ligands, minimizing both time and financial resources for the characterization of their psychedelic effects.

Effectiveness of a Web-Based Intervention for Preventing Substance Use in Young Adults in Taiwan: Quasi-Experimental Study

BACKGROUND

Substance use has been one of the most alarming public health problems worldwide, particularly among younger generations.

OBJECTIVE

This study evaluated the effectiveness of a web-based substance use prevention intervention targeted at adults aged 20-29 years.

METHODS

The intervention materials comprised 5 sets of infographics and 1 animation, all of which focused on mixed themes: (1) the concept of substance use and its harmful effects on health; (2) misinformation regarding new psychoactive substances; (3) regulation of illicit drugs, particularly marijuana; (4) the brain disease model of addiction; (5) critical thinking skills that improve health literacy; and (6) decision-making and communication skills that help people refuse illegal drugs. The study assigned eligible participants into experimental and control groups on the basis of the parity of their participant numbers. These participants completed web-based baseline and follow-up questionnaires that assessed their knowledge, behavioral intention, self-efficacy, and life skills related to substance use prevention. Knowledge was assessed using 8 questions concerning understanding of substance use harms and the regulation of illicit drugs. Behavioral intention and self-efficacy were assessed using 5-point Likert-type scales. Participants' ability to apply life skills to avoid substance use was assessed using 3 testing scenarios regarding substance use. The study used generalized estimating equations to examine the intervention's effectiveness.

RESULTS

A total of 1065 participants (539 control and 526 experimental) completed the intervention and questionnaires in 2019. The average ages of the experimental and control groups were 25.68 (SD 2.71) and 25.66 (SD 2.69) years, respectively. The study observed no significant differences in the demographic variables between the 2 groups. The results of the generalized estimating equation analyses indicated that the intervention significantly improved participants' knowledge (P<.001), behavioral intention (P<.001), and self-efficacy (P<.001) but not their life skills (P=.61) related to substance use prevention. Participants in the experimental group responded to a satisfaction survey with positive feedback on the intervention.

CONCLUSIONS

The web-based intervention was effective in improving participants' knowledge, behavioral intention, and self-efficacy concerning substance use prevention. The findings support continued efforts to use web-based interventions to prevent substance use among young adults.

Smart Multiplex Point-of-Care Platform for Simultaneous Drug Monitoring

Recently, illicit drug use has become more widespread and is linked to problems with crime and public health. These drugs disrupt consciousness, affecting perceptions and feelings. Combining stimulants and depressants to suppress the effect of drugs has become the most common reason for drug overdose deaths. On-site platforms for illicit-drug detection have gained an important role in dealing, without any excess equipment, long process, and training, with drug abuse and drug trafficking. Consequently, the development of rapid, sensitive, noninvasive, and reliable multiplex drug-detecting platforms has become a major necessity. In this study, a multiplex laser-scribed graphene (LSG) sensing platform with one counter, one reference, and three working electrodes was developed for rapid and sensitive electrochemical detection of amphetamine (AMP), cocaine (COC), and benzodiazepine (BZD) simultaneously in saliva samples. The multidetection sensing system was combined with a custom-made potentiostat to achieve a complete point-of-care (POC) platform. Smartphone integration was achieved by a customized application to operate, display, and send data. To the best of our knowledge, this is the first multiplex LSG-based electrochemical platform designed for illicit-drug detection with a custom-made potentiostat device to build a complete POC platform. Each working electrode was optimized with standard solutions of AMP, COC, and BZD in the concentration range of 1.0 pg/mL-500 ng/mL. The detection limit of each illicit drug was calculated as 4.3 ng/mL for AMP, 9.7 ng/mL for BZD, and 9.0 ng/mL for COC. Healthy and MET (methamphetamine) patient saliva samples were used for the clinical study. The multiplex LSG sensor was able to detect target analytes in real saliva samples successfully. This multiplex detection device serves the role of a practical and affordable alternative to conventional drug-detection methods by combining multiple drug detections in one portable platform.

Substance use, harm reduction attitudes and behaviors among attendees of nature rave parties in Israel

BACKGROUND

Few studies have analyzed harm reduction behaviors and attitudes among rave party attendees. Since the late 1980s, there has been a large Israeli rave scene, also known as 'Nature Parties'. However, only a few studies have been conducted among nature party attendees and almost all of them are from a qualitative perspective. This study's aim was to fill the gap and conduct quantitative research to investigate the patterns of substance use, harm reduction attitudes and behaviors among Israeli nature rave party attendees.

METHODS

A cross-sectional online survey recruited 1,206 people who reported having attended nature rave parties. All of the participants were aged 18-60 years (M = 29.9; SD = 7.4), and 770 (64%) were male.

RESULTS

The most common illicit substances used at Israeli nature rave parties in the past year were cannabis (62.2%), followed by LSD (41.4%), MDMA (31.7%), mushrooms/psilocybin (23.9%), ketamine (19.6%) and cocaine (17.2%). A significant but weak association was found between harm reduction behaviors and attitudes toward harm reduction interventions (r = .26, p < .001) and attitudes toward drug testing kits (r = .33, p < .001). It seems that although we found higher positive harm reduction attitudes, it is harder to implement harm reduction behaviors. Logistic regressions demonstrated stronger associations with high harm reduction behaviors and higher levels of positive attitudes toward drug testing kits (OR = 4.53; CI 2.97-6.90; p < .001), higher levels of positive attitudes toward harm reduction interventions (OR = 4.06; CI 2.62-6.29; p < .001), marital status of widower/divorced (OR = 2.22; CI 1.49-3.32; p < .001), using MDMA (OR = 1.63; CI 1.19-2.23; p <  = .01) and using LSD (OR = 1.41; CI 1.03-1.94; p <  = .05).

CONCLUSIONS

Formal harm reduction policies and interventions are needed for Israeli nature rave parties in addition to prevention and information programs, which are also very rare. Future studies should examine the subjects of harm reduction attitudes and behaviors among the public, policy makers and professionals.

Prevalence and predictors of tobacco, alcohol and illicit drug experimentation among Tunisian middle and high school-adolescents

OBJECTIVES

Psychoactive substance experimentation among Tunisian adolescents remains one of the most threatening public health concerns. In spite of this, little is known about the prevalence and predictors of these behaviors in the Tunisian context. This study aims to assess the prevalence of tobacco, alcohol and illicit drug experimentation and its predictive factors among adolescents in the delegation of Nfidha, Sousse governorate, Tunisia.

METHODS

We conducted a cross sectional study in middle and high schools in the delegation of Nfidha, Sousse governorate, Tunisia, during the first trimester of the 2019-2020 school year using an anonymous questionnaire self-administered to a randomly drawn representative sample of 1,352 pupils. Data collected included socio-demographic characteristics, substance experimentation among school-adolescents, academic performance as well as family and peer' factors.

RESULTS

Tobacco was the most commonly experimented substance with a prevalence rate of 17.5 % (CI 95 %: 14.8-18.8 %). The prevalence of alcohol and illicit drugs use were 3.3 % [CI 95 %: (2.1-3.9 %)] and 2 % [CI 95 %: (1.1-2.6 %)] respectively. Being male (Adjusted (AOR)=4.09, p<0.001), being a high school pupil (AOR=2.81, p<0.001), having experiencing academic failure (AOR=1.60, p=0.007) and having a father and siblings who use tobacco (AOR=1.72, p=0.002; AOR=2.03, p=0.001 respectively) were the predictors of tobacco experimentation in the multivariate logistic regression analysis. Additionally, being male (AOR=8.40, p<0.001), having experienced academic failure (AOR=2.76, p=0.017) as well as having a father and siblings who use alcohol (AOR=5.90, p<0.001; AOR=3.03, p=0.045 respectively) and having experienced tobacco (AOR=4.28, p<0.001) were the determinants of alcohol experimentation. Similarly, having a history of academic failure (AOR=3.44, p=0.041), having peers who use illicit drugs (AOR=3.22, p=0.028), having a history of tobacco and alcohol experimentation (AOR=6.52, p<0.001; AOR=3.49, p=0.046 respectively) were the predictors of illicit drug experimentation among adolescents.

CONCLUSIONS

A substantial number of socio-demographic and environmental factors have been identified as being involved in experimentation with psychoactive substance during adolescence. Therefore, further prevention programs targeting not only adolescents, but also all risk factors are needed.

The impacts of COVID-19 measures on drug markets and drug use among a cohort of people who use methamphetamine in Victoria, Australia

BACKGROUND AND AIMS

Few studies of the impacts of the coronavirus disease 2019 (COVID-19) public health measures on drug markets and drug use patterns have used longitudinal data. We aimed to examine whether COVID-19 measures were associated with increases in methamphetamine price, decreases in methamphetamine use frequency and subsequent changes in secondary outcomes of other drug use frequency in metropolitan Melbourne and regional Victoria.

DESIGN

Longitudinal analysis framework was used from a longitudinal cohort of people who use methamphetamine.

SETTING

Victoria state, Australia.

PARTICIPANTS

One hundred eighty-five VMAX study participants who reported a methamphetamine purchase after the onset of the pandemic were used for the price paid analysis. Methamphetamine or other drug use frequency analysis was performed using 277 participants who used methamphetamine during the pandemic or in the year before the pandemic.

MEASUREMENTS

Price paid per gram of methamphetamine derived from the most recent purchase price and most recent purchase quantity. Frequency of methamphetamine and other drug use measured as the average number of days per week used in the last month.

FINDINGS

Compared with pre-COVID-19 period, methamphetamine prices increased by AUD351.63 (P value <0.001) and by AUD456.51 (P value <0.001) in Melbourne and regional Victoria, respectively, during the period in which the most intense public health measures were implemented in Victoria. Although prices decreased after harder restrictions were lifted (by AUD232.84, P value <0.001 and AUD263.68, P value <0.001, in Melbourne and regional Victoria, respectively), they remained higher than pre-COVID-19 levels. A complementary 76% decrease was observed in relation to methamphetamine use frequency in regional Victoria (P value = 0.006) that was not offset by any changes in the frequency of use of other drugs such as alcohol, tobacco or other illicit drugs.

CONCLUSION

COVID-19 public health measures in Victoria state, Australia, appear to have been associated with major price changes in the methamphetamine market and decreased frequency of use of the drug.

Festivals following the easing of COVID-19 restrictions: Prevalence of new psychoactive substances and illicit drugs

The market for illicit drugs and new psychoactive substances (NPS) has grown significantly and people attending festivals have been identified as being at high risk (high extent and frequency of substance use). Traditional public health surveillance data sources have limitations (high costs, long implementation times, and ethical issues) and wastewater-based epidemiology (WBE) can cost-effectively support surveillance efforts. Influent wastewater samples were analyzed for NPS and illicit drug consumption collected during New Year period (from 29-Dec-2021 to 4-Jan-2022) and a summer Festival (from 29-June-2022 to 12-July-2022) in a large city in Spain. Samples were analyzed for phenethylamines, cathinones, opioids, benzodiazepines, plant-based NPS, dissociatives, and the illicit drugs methamphetamine, MDA, MDMA, ketamine, heroin, cocaine, and pseudoephedrine by liquid chromatography mass spectrometry. High consumption rates of specific NPS and established illicit drugs were identified at the peak of each event. Furthermore, a dynamic change in NPS use (presence and absence of substances) was detected over a period of six months. Eleven NPS, including synthetic cathinones, benzodiazepines, plant-based NPS and dissociatives, and seven illicit drugs were found across both the New Year and summer Festival. Statistically significant differences (p < 0.05) were seen for 3-MMC (New Year vs summer Festival), eutylone (New Year vs summer Festival), cocaine (summer Festival vs normal week and summer Festival vs New Year), MDMA (New Year vs normal week and summer Festival vs normal week), heroin (summer Festival vs New Year) and pseudoephedrine (summer Festival vs New Year). This WBE study assessed the prevalence of NPS and illicit drugs at festivals following the reduction of the COVID-19 pandemic restrictions highlighting the high use of specific substances at the peak of each event. This approach identified in a cost-effective and timely manner without any ethical issues the most used drugs and changes in use patterns and, thus, can complement public health information.

Does diabetic ketoacidosis at diagnosis of type 1 diabetes mellitus predict poorer long-term glycemic control

BACKGROUND

Diabetic ketoacidosis (DKA) is a life-threatening complication of type 1 diabetes mellitus.

AIMS

This study aimed to determine (1) whether DKA at diagnosis of type 1 diabetes is associated with poorer long-term glycemic control and (2) whether there are confounding factors which may impact the mode of presentation of type 1 diabetes mellitus or subsequent glycemic control.

METHODS

This study was conducted via review of 102 patient files extracted from the Young Person's Type 1 Diabetes Clinic at Cork University Hospital. Glycemic control was measured using the average of the patient's three most recent HbA1C levels, recorded a median of 11 years post-diagnosis of type 1 diabetes mellitus.

RESULTS

Data analysis revealed a positive association between DKA at diagnosis and poorer long-term glycemic control, with HbA1c levels tracking 6.58 mmol/mol (0.6%) higher at follow up in the group with DKA compared to the group without DKA at diagnosis. Certain sociodemographic factors were found to predict worse glycemic control at follow-up: Individuals using recreational drugs and those reporting mental health difficulties were found to have higher levels of HbA1C at follow up (p = ·006,·012, respectively) compared to individuals who did not.

CONCLUSIONS

Diabetic ketoacidosis at diagnosis of type 1 diabetes mellitus was shown to be associated with poorer long-term glycemic control in this study. Furthermore, individuals who utilize recreational drugs or have mental health difficulties had significantly worse glycemic control at follow-up.

Evaluating Technologies to Identify Fentanyl and Adulterants in Street Drug Paraphernalia: Qualitative Perspectives of Service Providers and Their Clientele

Background: Opioid overdose deaths continue to present major public health challenges in the U.S. Harm reduction agencies have begun using drug checking technologies to identify adulterants in the local drug supply and reduce overdose risk among people who use drugs (PWUD). Through qualitative and ethnographic methods, we assess the use of portable mass spectrometers at a harm reduction agency in a Northeastern U.S. city. Methods: We conducted participant observation, and on-the-spot qualitative interviews with harm-reduction staff members (n = 10) and their clientele (n = 17) between May 2019 and December 2020. Interviews explored emic views on drug checking (process, logistics, technology), and perceived benefits and challenges. We used thematic content analysis techniques to code and analyze interview transcriptions. Results: Implementation and use of drug checking devices were not free of challenges and malfunctions, often delaying drug checking opportunities and increasing suspicions and distrust among clients. Yet, staff members perceived that when working properly, or in conjunction with an additional device, they offered information about purchased drugs that could empower clients and potentially lead to positive behavior change. Use of these devices also enhanced engagement between harm reduction staff and PWUD, facilitating meaningful conversations around self-advocacy and harm reduction engagement. Conclusion: We report qualitative findings on the experiences and perceptions of drug checking devices among harm reduction staff and PWUD. Our findings indicate that use of this technology has the potential to decrease risk behaviors, expand health promotion services, and help reduce high rates of fentanyl-related overdose.

Current attitudes toward drug checking services and a comparison of expected with actual drugs present in street drug samples collected from opioid users

BACKGROUND

The opioid epidemic continues to be associated with high numbers of fatalities in the USA and other countries, driven mainly by the inclusion of potent synthetic opioids in street drugs. Drug checking by means of various technologies is being increasingly implemented as a harm reduction strategy to inform users about constituent drugs in their street samples. We assessed how valued drug checking services (DCS) would be for opioid street drug users given the ubiquity of fentanyl and related analogs in the drug supply, the information they would most value from drug checking, and compared expected versus actual constituent drugs in collected samples.

METHODS

A convenience sample of opioid street drug users (N = 118) was recruited from two syringe service exchange programs in Chicago between 2021 and 2022. We administered brief surveys asking about overdose history, whether fentanyl was their preferred opioid, and interest in DCS. We also collected drug samples and asked participants what drug(s) they expected were in the sample. Provided samples were analyzed using LC-MS technology and the results compared to their expected drugs.

RESULTS

Participants reported an average of 4.4 lifetime overdoses (SD = 4.8, range = 0-20) and 1.1 (SD = 1.8, range = 0-10) past-year overdoses. A majority (92.1%) believed they had recently used drugs containing fentanyl whether intentionally or unintentionally. Opinions about the desirability of fentanyl were mixed with 56.1% indicating they did not and 38.0% indicating they did prefer fentanyl over other opioids, mainly heroin. Attitudes toward DCS indicated a general but not uniform receptiveness with a majority indicating interest in DCS though sizeable minorities believed DCS was "too much trouble" (25.2%) or there was "no point" in testing (35.4%). Participants were especially inaccurate identifying common cutting agents and potentiating drugs such as diphenhydramine in their samples (sensitivity = .17).

CONCLUSIONS

Results affirmed street drug users remain interested in using DCS to monitor their drugs and such services should be more widely available. Advanced checking technologies that provide information on the relative quantities and the different drugs present in a given sample available at point-of-care, would be most valuable but remain challenging to implement.

Community-Engaged Research Ethics Training (CERET): developing accessible and relevant research ethics training for community-based participatory research with people with lived and living experience using illicit drugs and harm reduction workers

BACKGROUND

Community-based participatory research (CBPR) can directly involve non-academic community members in the research process. Existing resources for research ethics training can be inaccessible to team members without an academic background and do not attend to the full spectrum of ethical issues that arise through community-engaged research practices. We detail an approach to capacity building and training in research ethics in the context of CBPR with people who use(d) illicit drugs and harm reduction workers in Vancouver's Downtown Eastside neighborhood.

METHODS

A project team comprised of academic and community experts in CBPR, research ethics, and harm reduction met over five months to develop the Community-Engaged Research Ethics Training (CERET). The group distilled key principles and content from federal research ethics guidelines in Canada, and developed case examples to situate the principles in the context of research with people who use(d) illicit drugs and harm reduction workers. In addition to content related to federal ethics guidelines, the study team integrated additional content related to ethical issues that arise through community-based research, and ethical principles for research in the Downtown Eastside. Workshops were evaluated using a pre-post questionnaire with attendees.

RESULTS

Over the course of six weeks in January-February 2020, we delivered three in-person workshops for twelve attendees, most of whom were onboarding as peer research assistants with a community-based research project. Workshops were structured around key principles of research ethics: respect for persons, concern for welfare, and justice. The discussion-based format we deployed allowed for the bi-directional exchange of information between facilitators and attendees. Evaluation results suggest the CERET approach was effective, and attendees gained confidence and familiarity with workshop content across learning objectives.

CONCLUSIONS

The CERET initiative offers an accessible approach to fulfill institutional requirements while building capacity in research ethics for people who use(d) drugs and harm reduction workers. This approach recognizes community members as partners in ethical decision making throughout the research process and is aligned with values of CBPR. Building capacity around intrinsic and extrinsic dimensions of research ethics can prepare all study team members to attend to ethical issues that arise from CBPR.

Opium, phencyclidine, and crack cocaine smoking associations with lung and upper aerodigestive tract cancers: exploratory findings from a case-control study in Los Angeles County

Background: Illicit drug use has become a global epidemic, yet it is unclear if drug smoking increases the risk of tobacco-related cancers.Objectives: We aimed to evaluate hypothesized associations between smoking three drugs - opium, phencyclidine (PCP) and crack cocaine and lung and upper aerodigestive tract (UADT) cancers.Methods: A population-based case-control study with 611 lung cancer cases (50% male), 601 UADT cancers cases (76% male), and 1,040 controls (60% male) was conducted in Los Angeles County (1999-2004). Epidemiologic data including drug smoking histories were collected in face-to-face interviews. Associations were estimated with logistic regressions.Results: Adjusting for potential confounders, ever vs. never crack smoking was positively associated with UADT cancers (aOR = 1.56, 95% CI: 1.05, 2.33), and a dose-response relationship was observed for lifetime smoking frequency (p for trend = .024). Heavy (> median) vs. never crack smoking was associated with UADT cancers (aOR = 1.81, 95% CI: 1.07, 3.08) and lung cancer (aOR = 1.58, 95% CI: 0.88, 2.83). A positive association was also observed between heavy PCP smoking and UADT cancers (aOR = 2.29, 95% CI: 0.91, 5.79). Little or no associations were found between opium smoking and lung cancer or UADT cancers.Conclusion: The positive associations between illicit drug use and lung and/or UADT cancers suggest that smoking these drugs may increase the risk of tobacco-related cancers. Despite the low frequency of drug smoking and possible residual confounding, our findings may provide additional insights on the development of lung and UADT cancers.

Risk and Protective Factors for the Use of Illicit Drugs: Perspective of the Users

ABSTRACT

This article aimed to describe the perspective of people who make harmful use of illicit substances on the contributions of risk and protective factors to the development of problems related to drug use. One hundred eleven participants were recruited from a health service for drug users in a city in the interior of the state of São Paulo through posters with information, distribution of brochures, and snowball sampling technique. The sample consists of 51.9% men and 48.1% women, with 81.3% single and 10.3% married. Among them, 54.2% of participants completed high school, 64.1% were Catholic, and 34% rarely practiced their religion. The results on risk factors were classified into three domains, namely, "personal characteristics and behaviors," "family circumstances," and "other social pressures," and those on protective factors were also classified into three domains, namely, "personal characteristics and behaviors," "family circumstances," and "circumstances in the community." The data make it possible to guide the incorporation of multiple strategies to protect the consumption of illicit drugs in human biopsychosocial development, especially among children and adolescents.

Psychosocial functioning associated with prescription stimulant and opioid misuse versus illicit drug use among college students

Objective: College students' prescription stimulant and opioid misuse (PSM and POM) share psychosocial risks with other substance use. We sought to extend a prior study of these issues. Methods: National College Health Assessment (2015-2016) participants ages 18-24 years (n = 79,336) reporting 12-month PSM (defined as use of a drug not prescribed to them), 30-day other illicit drug use (non-cannabis), both, or neither, were compared on other substance use, psychopathology, academic adjustment, attention deficit hyperactivity disorder, and chronic pain. Models were repeated for POM. Results: Relative to those who only misused the prescription drug, those who used other illicit drugs had lower odds of chronic pain and academic problems, but higher odds on nearly every other outcome especially if they also misused the prescription drug. Conclusions: Findings suggest PSM and POM are on a continuum of risk shared with illicit drug use, but also are linked to outcomes specific to these drugs' perceived medical purposes.

Reproductive health syndemics impact retention in care among women living with HIV in Rio de Janeiro, Brazil

Syndemic psychosocial and reproductive factors affecting women's retention in HIV care remain understudied. We analyzed correlates of non-retention in a cohort of women with HIV in Brazil from 2000‒2015. Participants self-reported exposure to physical/sexual violence, illicit drug use, adolescent pregnancy, or induced abortion. Lifetime history of these psychosocial stressors were used to create a syndemic score based on the presence or absence of these conditions. All dichotomous variables were summed (range 0 to 4), with greater scores indicating more syndemic factors experienced. Logistic regression models identified predictors of non-retention, defined as < 2 HIV viral load or CD4 results within the first year of enrollment. Of 915 women, non-retention was observed for 18%. Prevalence of syndemic factors was adolescent pregnancy (53.2%), physical/sexual violence (38.3%), induced abortion (27.3%), and illicit drug use (17.2%); 41.2% experienced ≥ 2 syndemic conditions. Syndemic scores of 2 and 3 were associated with non-retention, as well as low education, years with HIV and seroprevalent syphilis. Psychosocial and reproductive syndemics can limit women's retention in HIV care. Syphilis infection predicted non-retention and could be explored as a syndemic factor in future studies.

Dispensary Staff Perceptions About the Benefits, Risks, and Safety of Cannabis for Medical Purposes

BACKGROUND

Therapeutic use of cannabis is common in the United States (up to 18.7% of Americans aged ≥12), and dispensaries in the US are proliferating rapidly. However, the efficacy profile of medical cannabis is unclear, and customers often rely on dispensary staff for purchasing decisions. The objective was to describe cannabis dispensary staff perceptions of medical cannabis benefits and risks, as well as its safety in high-risk populations.

METHODS

Online Survey study conducted using Qualtrics from February 13, 2020 to October 2, 2020 with a national sample of dispensary staff who reportedinteracting with customers in a cannabis dispensary selling tetrahydrocannabinol-containing products. Participants were queried about benefits ("helpfulness") and risks ("worry") about cannabis for a variety of medical conditions, and safety in older adults and pregnant women on a five-point Likert scale. These results were then collapsed into three categories including "neutral" (3/5). "I don't know" (uncertainty) was a response option for helpfulness and safety.

RESULTS

Participants (n = 434) were from 29 states and included patient-facing dispensary staff (40%); managers (32%); pharmacists (13%); and physicians, nurse practitioners, or physician assistants (5%). Over 80% of participants perceived cannabis as helpful for post-traumatic stress disorder (88.7%), epilepsy (85.3%) and cancer (83.4%). Generally, participants were not concerned about potential cannabis risks, including increased use of illicit drugs (76.3%), decreases in intelligence (74.4%), disrupted sleep (71.7%), and new/worsening health problems from medical cannabis use (70.7%). Cannabis was considered safe in older adults by 81.3% of participants, though there was much less consensus on safety in pregnancy.

CONCLUSIONS

Cannabis dispensary staff generally view medical cannabis as beneficial and low-risk. However, improvements in dispensary staff training, an increased role for certifying clinicians, and interventions to reduce dispensary staff concerns (e.g., cost, judgment) may improve evidence-based staff recommendations to patients seeking medical cannabis.

Widespread Distribution of Xylazine Detected Throughout the United States in Healthcare Patient Samples

OBJECTIVES

Xylazine is a tranquilizer commonly added into the illicit drug supply and a likely contributor to overdoses because it does not respond to naloxone reversal. The objective of this study was to perform a retrospective data analysis on xylazine-positive samples collected from patients in various outpatient healthcare settings to illustrate geographic distribution and common copositive substances, which may also contribute to risk of adverse events.

METHODS

Samples for which providers ordered testing for xylazine were subjected to enzymatic hydrolysis, extracted, and analyzed using liquid chromatography-tandem mass spectrometry. Retrospective analysis was performed on xylazine-positive samples collected from April 2021 to March 2022, to include geographic location and copositive substances.

RESULTS

Xylazine was identified in 413 of 59,498 samples from adults aged 20-73 years and originated from 25 of the 39 states where xylazine testing was ordered. The most common routine substances detected with xylazine were fentanyl, buprenorphine, naloxone, cocaine, d -methamphetamine, and delta-9-tetrahydrocannabinol. The most common designer drugs detected included fentanyl analogs, isotonitazene, and designer benzodiazepines.

CONCLUSIONS

Xylazine is geographically spread throughout the United States, indicative of a wide incorporation into the illicit drug supply. These findings differ from previous studies in that these samples originated from healthcare providers in routine care settings, where other reports typically involve overdose deaths. This analysis illustrates that routine testing for xylazine in outpatient settings can afford providers the opportunity to educate individuals and adjust harm reduction measures to potentially mitigate overdose risk.
