Stigma Toward Substance Dependence: Causes, Consequences, and Potential Interventions

Substance dependence is a prevalent and urgent public health problem. In 2021, 60 million Americans reported abusing alcohol within the month prior to being surveyed, and nearly 20 million Americans reported using illegal drugs (e.g., heroin) or prescription drugs (e.g., opioids) for nonmedical reasons in the year before. Drug-involved overdose rates have been steadily increasing over the past 20 years. This increase has been primarily driven by opioid and stimulant use. Despite its prevalence, drug dependence is one of the most stigmatized health conditions. Stigma has myriad negative consequences for its targets, including limiting their access to employment and housing, disrupting interpersonal relationships, harming physical and mental health, and reducing help-seeking. However, because research on stigma toward people with substance use disorders (SUDs) is relatively sparse compared with research on stigma toward other mental illnesses, the field lacks a comprehensive understanding of the causes and consequences of SUD stigma. Moreover, it remains unclear how, if at all, these factors differ from other types of mental illness stigma. The goal of this review is to take stock of the literature on SUD stigma, providing a clear set of foundational principles and a blueprint for future research and translational activity.

Negative changes in illicit drug supply during COVID-19: Associations with use of overdose prevention and health services among women sex workers who use drugs (2020-2021)

BACKGROUND

Women sex workers are a highly criminalized population who are over-represented amongst people who use drugs (PWUD) and face gaps in overdose prevention and harm reduction services. British Columbia, Canada continues to face a pronounced drug poisoning crisis of the illicit drug supply, which has intensified during the COVID-19 pandemic. Our objective was to examine the prevalence and structural correlates of experiencing negative changes in illicit drug supply (e.g., availability, quality, cost, or access to drugs) amongst women sex workers who use drugs during the first year of the COVID-19 pandemic.

METHODS

Cross-sectional questionnaire data were drawn from a prospective, community-based cohort of women sex workers in Vancouver (AESHA) from April 2020 to 2021. Bivariate and multivariable logistic regression was used to investigate structural correlates of negative changes in drug supply during COVID-19 among sex workers who use drugs.

RESULTS

Among 179 sex workers who use drugs, 68.2% reported experiencing negative changes to drug supply during COVID-19, 54.2% recently accessed overdose prevention sites, and 44.7% reported experiencing recent healthcare barriers. In multivariable analysis adjusted for injection drug use, women who reported negative changes in illicit drug supply had higher odds of experiencing recent healthcare barriers (AOR 2.28, 95%CI 1.12-4.62); those recently accessing overdose prevention sites (AOR 1.75, 95%CI 0.86-3.54) faced marginally higher odds also.

CONCLUSIONS

Over two-thirds of participants experienced negative changes to illicit drug supply during the first year of the COVID-19 pandemic. The association between experiencing negative changes in the illicit drug supply and accessing overdose prevention services highlights the agency of women in taking measures to address overdose-related risks. Highly criminalized women who experience structural barriers to direct services are also vulnerable to fluctuations in the illicit drug supply. Attenuating health consequences requires interventions tailored to sex workers' needs.

The fourth wave of the overdose crisis: Examining the prominent role of psychomotor stimulants with and without fentanyl

The current overdose and broader public health crisis involving illicit drug use is often referred to as the "opioid" or "fentanyl" crisis. Clearly there is extensive data on the profound damage done by opioids over the past 20 years and specifically by fentanyl in the past 5 years. However, there is an extensive array of data that suggests there is more to the current crisis than opioids/fentanyl. Much recent evidence indicates that methamphetamine and cocaine are playing a substantial and increasing role in the illicit drug crisis in the US-the 4th wave. This paper reviews data that illustrate the role of psychomotor stimulants in fatal overdoses, nonfatal overdoses, and emergency department visits. Despite the major detrimental role that stimulants are having on the public health in the US in 2023, there is virtually no evidence-based treatment available in practice for people with stimulant use disorder (StimUD). Although there are no medications with FDA-approval for the treatment of StimUD, there is a behavioral treatment, contingency management (CM), with over 3 decades of robust research supporting its efficacy for individuals with StimUD. Despite the overwhelming evidence supporting CM, it is not being widely used in routine treatment outside the VA healthcare system. This paper reviews some of the (a) evidence for CM, (b) CM protocol design elements that require consideration, (c) current obstacles to the widespread implementation of CM, and (d) strategies for addressing these obstacles. Overcoming these obstacles is a priority to allow routine use of CM as a treatment for StimUD.

Risky Sexual Behaviour and Sexual Victimization among Young People with Risky Substance Use in Europe-Perspectives from Belgium, Sweden, the Czech Republic, and Germany

BACKGROUND

Research indicates that among the risks associated with young people's alcohol and illicit drug use are sexual risks. However, insights into co-occurrence of substance use and sexual risks in adolescent samples and possible differences across countries are limited.

METHODS

A sample of 1449 adolescents from Belgium, Sweden, the Czech Republic, and Germany screened positive for risky alcohol/illicit drug use in a web-based intervention against alcohol and illicit drug use. They also reported incidents of sex while being drunk and/or high on drugs, condomless sex on these occasions, and sexualized touching and sexual victimization while being drunk or high on drugs.

RESULTS

In the sample, 21.5% of the participants reported sexualized touching, 9.9% being victim to sexual assault, and 49.8% having had sex while being drunk and/or high on drugs; of the latter, 48.3% had condomless sex. Reports on having had sex while being drunk and/or high on drugs were associated with higher levels of past 30-day binge drinking. Being a victim of sexual assault was associated with past 30-day binge drinking only in young men.

CONCLUSION

When devising preventive interventions against risky substance use in adolescents, an additional focus should be set on integrating steps against sexual risks.

Motivational characteristics of recreational drug use among emerging adults in social settings: an integrative literature review

Introduction

Recreational drug use by emerging adults has been identified as an increasingly normalized trend in social contexts. It has been documented that the consumption of these substances regularly occurs at music festivals, raves, nightlife and party settings. While it is known that emerging adults participate in these risk-taking behaviors, what is not known is their motivational characteristics for use. The aim of this review to identify and review literature describing the motivations for recreational drug use and drug choice (excluding alcohol, cannabis and tobacco) by emerging adults in social settings to inform selection of appropriately aligned harm reduction education and health messaging interventions.

Methods

Whittemore and Knafl's (2005) integrative approach was used to conduct the review. This integrative review was based on a three-step search strategy identifying 2,772 articles published between 2000 and 2022. Eleven studies were included in the review. This review explores the following areas: drug use settings, concurrent drug use, consumer drug knowledge, motives of use including likes and dislikes and peer influence.

Results

A range of factors influence motivations of emerging adults to participate in recreational drug use. Similar to the consumption of alcohol, the use of recreational drugs by emerging adults is motivated by their perceived benefits and personal motivations to achieve euphoria, emotional intimacy, social benefits, peer influence, increased confidence and to decrease inhibitions. The review findings suggest that motivational factors that reinforce recreational drug use correlate with the desire to break away from the mundane by seeking pleasure and for the opportunity to create novel experiences. Beliefs about the positive and negative impacts of drug use, together with the desire to achieve emotional satisfaction influence drug taking activity.

Conclusion

Recreational drug use has become an increased societal norm amongst drug using peer groups and cannot be entirely prevented. It is to be noted that emerging adults have a basic understanding concerning recreational drugs, however, consumer drug knowledge and interventions that target illicit substances is lacking and should be addressed in future research. Festivals, raves and nightlife settings provide opportunity to implement health promotion as it reaches large number of vulnerable individuals in a short period of time.

Wastewater profiling of illicit drugs, an estimation of community consumption: A case study of eThekwini Metropolitan Municipality, South Africa

Estimation of community-wide consumption of illicit drugs through wastewater analysis is a new concept in Africa although widely applied in developed nations as wastewater-based epidemiology (WBE). It is an important tool that can be used in understanding supply and demand patterns of illicit drug use on a local, national, and international scale. Information on illicit drug use is currently limited in Africa, because of a lack of monitoring structures by governments and financial constraints. This study hopes to bridge that gap by contributing to Africa's baseline information on illicit drug use. This study provides the first application of wastewater analysis to quantitatively evaluate daily illicit drug use in the eThekwini Metropolitan Municipality of KwaZulu-Natal Province of South Africa by quantifying the major urinary excreted metabolites, called drug target residues (DTRs), in raw wastewater from four major wastewater treatment plants (WWTPs) sampled for a week. The results showed that cocaine was the dominant illicit drug consumed in the catchment followed by amphetamine, methamphetamine, 3,4-methylenedioxymethamphetamine and 3,4-methylenedioxyamphetamine, with a per capita use of 360-3000 mg day-1 1000 inh-1, 47-800 mg day-1 1000 inh-1, 19-120 mg day -1 1000 inh-1, not detected (ND) to 4.9 mg day-1 1000 inh-1, and ND to 410 g day-1 1000 inh-1 respectively. The weekly usage patterns between the four WWTPs differed probably due to the lifestyle of the populace serving the different WWTPs. These results provide useful data on illicit drug use in eThekwini that can be utilised by public health agencies to implement suitable response strategies.

Relapses in Illicit Drug Use Among Probationers: Results in a Risk Group of Public Health Services in Bavaria

Objective: We aimed to identify in this study time trends of relapses in the illicit consumption of narcotics in a special at-risk population of former drug users under a public health perspective. Methods: In a pooled dataset of 14 consecutive calendar years (2006-2019), the use of seven different narcotic substances was studied in 380 persons with a total of 2,928 urine samples which were analyzed using a valid marker system for narcotic residues. Results: During the entire observation period, the relapse rate for cannabinoids and opiates was the highest despite abstinence requirements. It was noticeable that the relapses across all narcotics groups occurred primarily during the first 3 years of the probation period (90%) with a decrease in illegal consumption during the following years of the observation period. Conclusion: Special attention should be paid to probationers at the beginning of the probation period to develop more effective prevention strategies for substance abstinence by all involved actors in public health services.

Naloxone prescriptions among patients with a substance use disorder and a positive fentanyl urine drug screen presenting to the emergency department

BACKGROUND

Over 109,000 people in the USA died from a drug overdose in 2022. More alarming is the amount of drug overdose deaths involving synthetic opioids other than methadone (SOOM), primarily fentanyl. From 2015 to 2020, the number of drug overdose deaths from SOOM increased 5.9-fold. SOOM are commonly being found in many other drugs without the user's knowledge. Given the alarming number of overdose deaths from illicit drugs with SOOM, naloxone should be prescribed for all persons using illicit drugs regardless of if they knowingly use opioids. How often providers prescribe naloxone for these patients remains unknown. The aim of this study is to determine the rate of naloxone prescriptions given to patients with any substance use disorder, including when the patient has a urine drug screen positive for fentanyl. Secondary aims include determining what patient factors are associated with receiving a naloxone prescription.

METHODS

The design was a single-center retrospective cohort study on patients that presented to the Augusta University Medical Center emergency department between 2019 through 2021 and had an ICD-10 diagnosis of a substance use disorder. Analyses were conducted by logistic regression and t-test or Welch's t-test.

RESULTS

A total of 10,510 emergency department visits were by 6787 patients. Naloxone was prescribed in 16.3% of visits with an opioid-related discharge diagnosis and 8.4% of visits with a non-opioid substance use-related discharge diagnosis and a urine drug screen positive for fentanyl. Patients with a fentanyl positive urine drug screen had higher odds of receiving a naloxone prescription (aOR 5.80, 95% CI 2.76-12.20, p < 0.001). Patients with a psychiatric diagnosis had lower odds of being prescribed naloxone (aOR 0.51, p = 0.03). Patients who received naloxone had a lower number of visits (mean 1.23 vs. 1.55, p < 0.001). Patients with a urine drug screen positive for cocaine had higher odds of frequent visits (aOR 3.07, p = 0.01).

CONCLUSIONS

Findings should remind providers to prescribe naloxone to all patients with a substance use disorder, especially those with a positive fentanyl urine drug screen or a co-occurring psychiatric condition. Results also show that cocaine use continues to increase healthcare utilization.

Sociodemographic profiles and determinants of relapse risks among people with substance use disorders in the Philippines: A survey in community and residential care settings

BACKGROUND

Methamphetamine use is a major social and health issue in the Philippines. Former president Rodrigo Duterte prioritized combating illicit drugs, and the government launched an anti-drug campaign. People with substance use disorders (SUD) receive treatment and care in the community or residential treatment at Treatment and Rehabilitation Centers (TRCs) established by the Department of Health. However, since the content and quality of service are not sufficient, there is an urgent need for improvement. To this end, it is necessary to understand demographic characteristics, the severity of drug use, and treatment needs of this population.

METHODS

We conducted a questionnaire survey of people with SUD in the community (n=308) and all TRC patients (n=1770) to obtain their demographic profiles. We also used the Drug Abuse Screening Test-20 (DAST-20) and the Stimulant Relapse Risk Scale (SRRS).

RESULTS

Based on DAST-20 scores, the severity of dependence was not well-matched to the care provided; 12.4% of the community sample was in the severe or substantial categories and 14.2% of the TRC sample was in the low category. The TRC sample had a significantly higher relapse risk than the community sample, which was associated with a lower educational attainment level and comorbid alcohol dependence.

CONCLUSIONS

It is important to use standardized psychometric tools to match treatment with the severity of drug dependence. In addition, a wide variety of medical and social services need to be provided based on consideration of treatment needs to improve the well-being of this population.

Racial Disparities in Drug Arrest Before and After De Facto Decriminalization in Baltimore

INTRODUCTION

To mitigate the harms of arrest and incarceration on health and racial equity, jurisdictions are increasingly enacting reforms to decriminalize drug possession through prosecutorial discretion (de facto). Impacts on health outcomes rely on whether this policy can reduce exposure to the carceral system among people who use drugs; however, data evaluating effects on arrest are lacking. This study explores the possible impacts of Baltimore City's enactment of de facto decriminalization on arrests by race.

METHODS

Police and court records were used to explore the possible impacts of Baltimore City's de facto decriminalization on street arrests and (processed) arrests advancing through the courts among people who use drugs. Interrupted time series models were used to compare pre-policy (January 2018-March 2020) trends with post-policy (April 2020-December 2021) trends in arrests for possession of drugs/paraphernalia and estimate racial disparities in street arrests (Black versus other races). Analyses were performed in February-May 2022.

RESULTS

The policy was associated with a significant and immediate decline in street and processed arrests for possession, which was not seen for other crime categories. Although declines were concentrated in the Black community, disparities in arresting persisted after the policy.

CONCLUSIONS

De facto decriminalization may be a promising strategy to reduce exposure to the carceral system, an established risk factor for overdose and other drug-related sequelae and a driver of racial disparities in the U.S. Further research is needed to elucidate the drivers of persisting racial disparities and disentangle policy effects from pandemic-related closures.

Detection of illicit psychoactive substances in the urine of mothers and newborn infants at a public hospital. Comparison between the 2009-2013 and 2014-2018 five-year periods

Introduction. The use of illicit psychoactive substances during pregnancy is a growing problem. Few Latin American maternity centers implement a screening strategy, and published data are scarce. Objectives. To compare the outcomes of 2 five-year periods of a postpartum strategy to screen for illicit psychoactive drugs. Population and methods. This was a cross-sectional study. Immunoassay detection in urine of mother-newborn infant dyads in an Argentine public hospital between 2009 and 2018. Results. Substances were detected in 76/191 dyads over 10 years. The most frequent detection criterion was reporting or history of drug use: 25/37 and 32/39 in each five-year period. Cannabis (21/37 and 26/39) and cocaine (19/37 and 16/39) predominated in both periods. No differences were observed in demographic, gynecological, pregnancy, or neonatal data between both five-year periods. Conclusions. No differences were found in the frequency or type of substances detected over 10 years.

Profile of patients with a positive HCV viral load in a large French psychiatric hospital (2019-2021): A case-control study

Hepatitis C virus (HCV) is highly prevalent in people with mental disorders (PWMDs). However, in the international context of HCV elimination, no previous study has explored the features of seropositive PWMDs with vs. without a positive viral load (VL). We retrospectively retrieved all HCV serology results of patients hospitalized in 2019, 2020 and 2021 in the second-largest psychiatric hospital of France. Using the medical records of all patients found seropositive for HCV, the following data were collected: sex (male, female), age (in years), previous history of illicit drug use except cannabis (yes or no) and previous history of incarceration (yes or no). We conducted a case-control comparison of these variables between the PWMDs who had and did not have a positive VL, thus providing odds ratios and 95% confidence intervals (ORs [95% CI]). In a total of 13,276 inpatients, 2540 (19.1%) underwent at least one HCV serology; 55 of them (2.16%) were found positive. A VL count was performed for 48 of them, finding 15 (31.3%) individuals with active HCV. Compared with those with a negative VL, these 15 individuals were less likely to have previous documented illicit drug use (OR = 0.18; 95% CI [0.05-0.68]) and to have been previously incarcerated (OR = 0.23; 95% CI [0.06-0.99]); age and sex did not statistically differ. In the context of HCV elimination, PWMDs yet to be treated for HCV are more likely to be those with no identified risk factor for HCV, which supports a strategy of systematic screening for HCV among PWMDs.

Guidelines and treatment for illicit drug related presentations in emergency departments: A scoping review

OBJECTIVE

This review aimed to identify current pharmacological and non-pharmacological treatment employed in emergency departments (EDs) for the management of patients presenting with illicit drug-related presentations (IDP) and compare current treatments with recommendations provided in guidelines.

METHOD

The review consists of English peer-reviewed journal articles and grey literature published in electronic databases: Ovid MEDLINE, PubMed, Embase Classic+Embase, Ovid Emcare and APA PsycInfo between 2015 and 2022.

RESULTS

Twelve studies were identified from the search, with agitation and aggression being the most common presentations, and cannabis being the most prevalent illicit drug. Ventilatory support and restraints were the most reported non-pharmacological interventions while benzodiazepines and antipsychotics were the most commonly prescribed pharmacological agents. Non-coercive de-escalation strategies were recommended in all guidelines, with verbal de-escalation being the initial approach before other interventions, such as medications and restraints. However, de-escalation strategies were not reported in any studies.

CONCLUSIONS

Pharmacological interventions for patients with IDP and related symptoms were in accordance with guidelines. Use of restraints was identified in included studies with notable lack of reporting of de-escalation strategies which may have been deemed insignificant and not reported. Future research could investigate the appropriateness of restrictive interventions as well as the employment of non-restrictive de-escalation strategies.

The Impact of Later Life Events on Cessation Motivation of Older Adults with Substance Use Disorder in Hong Kong

Life-course researchers have found that age-graded life events, such as marriage and employment, may provoke a turning point in the trajectories of substance use and motivate young adults with substance use disorder (SUD) to seek addiction treatment and cease illegal drug use. However, few studies have focused on the impact of the life events experienced by older adults with SUD in their later life on these trajectories. Even less is known about this phenomenon in non-Western contexts. Thus, we conducted interviews with 34 older individuals with SUD in Hong Kong and explored how later life events affected their motivation to cease illegal drug use. Our findings highlight the influence of age on how life events are experienced and the need for age-specific academic studies of substance use trajectories. The results also have implications for policymakers, as the criminalization and stigmatization of drug use may have a negative impact on the trajectories of substance use among older populations.

Lifestyles and Sexual Behaviour Among School-Going Adolescents: A Mediational Role of Mental Health

Sexual behaviour and mental health among adolescents are major public health issues. This study examines how lifestyles affect sexual behaviour among school-going adolescents in Malaysia, and the potential mediational role of mental health. It is the first to our knowledge to explore the mediating effect of mental health on sexual behaviour with a focus on a fast-growing developing country. Data were obtained from the National Health and Morbidity Survey 2017 (n = 27,497). Structural equation modelling was utilized to examine depression and anxiety as mediators of the relationships between sexual behaviour and smoking, alcohol drinking and illicit drug use, controlling for sociodemographic factors. Results showed that adolescents who smoked, consumed alcohol, used illicit drugs, and had depression and anxiety were more likely to engage in sexual behaviour than others. Depression and anxiety partially mediated the relationships between sexual behaviour and smoking, and illicit drug use. The association between alcohol drinking and sexual behaviour was fully mediated by depression and anxiety. In conclusion, lifestyles may affect sexual behaviour through mediation of mental health. Therefore, policymakers should take mental health factors into consideration when designing adolescent sexual behaviour preventative interventions.

Tobacco and Illicit Drug Use and Drug Use Disorders Among Employees of Businesses Affected by the 9/11 Attacks on the World Trade Center in New York City

OBJECTIVE

To study the New York City area population after the September 11, 2001, 9/11 attacks, focusing on tobacco and drug use and drug use disorders. An abundance of research has identified the important mental health sequelae stemming from exposure to disasters, especially vulnerability to the development of posttraumatic stress disorder (PTSD) and major depressive disorder (MDD). There also is a body of literature on the association of disaster exposure with alcohol use/misuse, but far less research on tobacco and other drug use/disorders.

METHODS

A terrorism-affected sample (N = 379) was assessed nearly 3 years after the attacks using structured diagnostic interviews, providing predisaster and postdisaster prevalence and incidence of tobacco and drug use, changes in tobacco and drug use, and predisaster and postdisaster prevalence and incidence of drug use disorders in relation to the 9/11 attacks. DSM-IV criteria were fully assessed using structured diagnostic interviews for psychiatric disorders including PTSD, MDD, panic disorder, generalized anxiety disorder, and alcohol and drug use disorders.

RESULTS

Tobacco use did not increase significantly, and no predictors of increased tobacco use could be found for any subgroups, including disaster trauma exposures. Drug use (largely cannabis) increased initially but decreased by 3 years after the attacks. Drug use disorders, which were associated with other psychiatric disorders, were rare and primarily began prior to 9/11.

CONCLUSIONS

The overall lack of increase of tobacco use or predictors of increased use found after the disaster and the low rates of new drug use disorders suggest that universal screening for increased tobacco use and new drug use disorders by clinicians may have very low yield. Regardless, postdisaster settings provide suitable circumstances for general discussions about self-care including concern for increased tobacco use, avoiding drug use, and guidance on healthier means of managing stress than through substances. Additionally, because existing tobacco and drug use are endemic in populations, the postdisaster setting can serve as a reminder for clinicians to assess these problems generally and provide appropriate referrals when needed. Postdisaster circumstances offer opportunities to disseminate and promote public health messages and address issues of substance use and misuse.

Factors associated with unsuccessful tuberculosis treatment among homeless persons in Brazil: A retrospective cohort study from 2015 to 2020

BACKGROUND

Tuberculosis (TB) is a preventable and a curable disease. In Brazil, TB treatment outcomes are particularly worse among homeless populations who are either of black race, malnourished or living with HIV/AIDS and other comorbidities. This study therefore evaluated factors associated with unsuccessful TB treatment among homeless population (HP) compared to those with shelter.

METHODOLOGY/PRINCIPAL FINDINGS

The study population was composed of 284,874 people diagnosed with TB in Brazil between 2015 and 2020 and reported in the Information System for Notifiable Diseases (SINAN), among which 7,749 (2.72%) were homeless and 277,125 (97.28%) were sheltered. Cox regression analysis was performed with both populations to identify factors associated with unsuccessful TB treatment, and significant predictors of TB treatment outcomes. Results show that HP are more susceptible to unfavorable outcomes when compared to sheltered people (Hazard Ratio (HR): 2.04, 95% CI 1.82-2.28). Among the HP, illicit drug use (HR: 1.38, 95% CI 1.09-1.74), mental disorders (HR: 2.12, 95% CI 1.08-4.15) and not receiving directed observed treatment (DOT) (HR: 18.37, 95% CI 12.23-27.58) are significant predictors of poor treatment outcomes. The use of illicit drugs (HR: 1.53, 95% CI 1.21-1.93) and lack of DOT (HR: 17.97, 95% CI 11.71-27.59) are associated with loss to follow-up, while lack of DOT (HR: 15.66, 95% CI 4.79-51.15) was associated with mortality among TB patients.

CONCLUSION/SIGNIFICANCE

Homeless population living in Brazil are twice at risk of having an unsuccessful treatment, compared to those who are sheltered, with illicit drugs use, mental disorders and lack of DOT as risk factors for unsuccessful TB outcomes. Our findings reinforce the arguments for an intersectoral and integral approach to address these determinants of health among the vulnerable homeless populations.

Substance Use, Sexual Agreements, and Sexual Risk Behaviors Among Adolescent Sexual Minority Males (Aged 13-17) in the United States

PURPOSE

Despite the fact that adolescence represents a distinct developmental period wherein dating and sexual relationships are emergent, much of what is known about substance use, sexual agreements, and sexual risk behaviors among adolescent sexual minority males (ASMM) is extrapolated from research on adults. This study tested associations between substance use and sexual risk behaviors among ASMM and examined whether relationship status and sexual agreements moderated these associations.

METHODS

Cross-sectional online survey data were collected from 2,892 HIV negative ASMM aged 13-17 years between November 2017 and March 2020. All were sexually active with male partners and not on pre-exposure prophylaxis. A multigroup hurdle model predicted the occurrence and frequency of condomless anal sex (CAS) with casual partners.

RESULTS

Non-monogamous ASMM were more likely to use illicit drugs and more likely to have CAS with casual partners compared with single ASMM and those in monogamous relationships. Among ASMM who had CAS at least once, those in relationships (both monogamous and nonmonogamous) had CAS more frequently than single ASMM. Binge drinking (odds ratio (OR) = 1.47, p < .001), cannabis (OR = 1.30, p < .001), and illicit drug use (including prescription drug misuse) (OR = 1.77, p < .001) were associated with the occurrence of CAS with casual partners but only binge drinking (rate ratio (RR) = 1.23, p = .027) and illicit drugs (RR = 1.75, p < .001) were associated with its frequency.

DISCUSSION

While results aligned with adult studies in many respects, unlike adult sexual minority males, these findings suggest partnered ASMM-particularly those in nonmonogamous relationships-were at highest risk of substance use and associated sexual HIV transmission risk.

Alarmingly high prevalence of high-risk drug use among palestinian males: a cross-sectional study

BACKGROUND

The unique socioeconomic context in Palestine, characterized by political and economic tensions, creates conditions that facilitate the spread of illicit drug use among Palestinians. This paper presents findings from a 2017 survey of high-risk drug use (HRDU) among males in four regions in Palestine: the West Bank (north, middle, and south) and the Gaza Strip. These findings are essential for developing effective policies to respond to the increasing use of drugs among Palestinians.

METHODS

Eligible participants were males aged 15 years and above who used at least one drug other than non-synthetic hashish or marijuana during the previous week. Participants underwent a face-to-face interview and had their drug use verified by urinalysis. Data were collected using respondent-driven sampling and data were analyzed using the successive sampling estimator. Multivariate regression analysis was conducted to examine factors associated with ever seeking rehabilitation services for illicit drug use in the West Bank and the Gaza Strip.

RESULTS

A total of 400 males who use drugs were sampled in Gaza, plus 299 in the south, 300 in the north, and 299 in the middle region of the West Bank. It is estimated that there are 26,500 male HRDUs in Palestine comprising 1.8% of the male population aged 15 and above. Findings indicate that polydrug use is a serious issue in Palestine, especially in the West Bank, and that synthetic marijuana is prevalent among teenagers and young adults.

CONCLUSIONS

Palestine must strengthen its national efforts to scale up harm reduction and treatment and care options for people suffering from drug use disorders, especially those involved in polydrug use. Additional measures are needed to prevent substance use among children and youth, support the families of people who use drugs, and ensure the continuity of HRDU services during emergencies.

Implementation of substance use screening in rural federally-qualified health center clinics identified high rates of unhealthy alcohol and cannabis use among adult primary care patients

BACKGROUND

Screening for substance use in rural primary care clinics faces unique challenges due to limited resources, high patient volumes, and multiple demands on providers. To explore the potential for electronic health record (EHR)-integrated screening in this context, we conducted an implementation feasibility study with a rural federally-qualified health center (FQHC) in Maine. This was an ancillary study to a NIDA Clinical Trials Network study of screening in urban primary care clinics (CTN-0062).

METHODS

Researchers worked with stakeholders from three FQHC clinics to define and implement their optimal screening approach. Clinics used the Tobacco, Alcohol, Prescription Medication, and Other Substance (TAPS) Tool, completed on tablet computers in the waiting room, and results were immediately recorded in the EHR. Adult patients presenting for annual preventive care visits, but not those with other visit types, were eligible for screening. Data were analyzed for the first 12 months following implementation at each clinic to assess screening rates and prevalence of reported unhealthy substance use, and documentation of counseling using an EHR-integrated clinical decision support tool, for patients screening positive for moderate-high risk alcohol or drug use.

RESULTS

Screening was completed by 3749 patients, representing 93.4% of those with screening-eligible annual preventive care visits, and 18.5% of adult patients presenting for any type of primary care visit. Screening was self-administered in 92.9% of cases. The prevalence of moderate-high risk substance use detected on screening was 14.6% for tobacco, 30.4% for alcohol, 10.8% for cannabis, 0.3% for illicit drugs, and 0.6% for non-medical use of prescription drugs. Brief substance use counseling was documented for 17.4% of patients with any moderate-high risk alcohol or drug use.

CONCLUSIONS

Self-administered EHR-integrated screening was feasible to implement, and detected substantial alcohol, cannabis, and tobacco use in rural FQHC clinics. Counseling was documented for a minority of patients with moderate-high risk use, possibly indicating a need for better support of primary care providers in addressing substance use. There is potential to broaden the reach of screening by offering it at routine medical visits rather than restricting to annual preventive care visits, within these and other rural primary care clinics.

Understanding polysubstance use at the daily and event levels: protocol for a mixed-methods qualitative and ecological momentary assessment study in a community-based sample of people who use illicit drugs in Oakland, California, USA

INTRODUCTION

Polysubstance use is extremely common among people who use illicit opioids in the USA. It is associated with poor substance use treatment outcomes, infectious disease risk and alarming rates of drug overdose. Nearly all extant literature examines polysubstance use over broad time frames, such as 30 days or 6 months. However, both substance use and overdose risk are episodic. To build a stronger understanding of polysubstance use and overdose risk, we need to expand the knowledge base to include daily-level and event-level data that examine how substances are used together, in which combinations and in which contexts. The study described in this protocol will use qualitative and ecological momentary assessment (EMA) methods to examine polysubstance use and overdose risk on a daily and event level.

METHODS AND ANALYSIS

This is a mixed-methods observational study with three phases. The first phase is formative, consisting of qualitative interviews with people who use multiple substances (N=20), to inform the development of items for the EMA component. The second phase is EMA data collection with people who use multiple substances (N=120), three times daily for 28 days. The third phase consists of mixed-methods inquiries with a subset of participants (N=20), using participant-level EMA data and qualitative techniques to build a nuanced understanding of the motivations and contexts of polysubstance use in everyday life. Analytical induction methods will be used to interpret qualitative data. Hierarchical linear modelling methods will be used to analyse EMA data.

ETHICS AND DISSEMINATION

This research has been reviewed and approved by the Institutional Review Board at RTI International (#MOD00001782 for EMA procedures and #MOD00001241 for qualitative procedures). Participants engage in an informed consent procedure for each component of the study. Data will be managed and shared per the National Institutes of Health extramural data sharing policy.

"Just another thing for me to stress off of": Responses to unintentional fentanyl use in a community-based study of people who use opioids

The unintentional consumption of fentanyl is a serious health risk for people who use illicit drugs. In an ongoing community-based study regarding polysubstance use among people who use opioids, we found that 17 of 58 (29%) of participants who did not endorse fentanyl use in the past thirty days tested positive for fentanyl during point-of-care urinalysis (UA). This paper describes the reactions and experiences of participants who were informed they had consumed fentanyl unintentionally, as well as how the research team handled the unanticipated occurrence of discordant results. Consistent with other recent studies, we found that people learning of unintentional fentanyl use expressed strong concerns about accidental overdose. It was common for participants to reflect on recent substance use experiences that were atypical and might have involved fentanyl, as well as to examine sources of recent drug purchases. While not all participants were surprised that they had unintentionally consumed fentanyl, all felt that learning their positive results was important due to risk of overdose. Research and medical staff have an opportunity to promote awareness of possible contamination by sharing and discussing UA test results with people who use drugs in non-judgmental manner. In addition to the widely promoted harm reduction strategy of testing drugs with fentanyl test strips, self-administered point-of-care UA, particularly after an unexpected reaction to using a drug, could provide useful information for people buying and using illicit drugs.

Drug use among medical students in São Paulo, Brazil: a cross-sectional study during the coronavirus disease 2019 pandemic

BACKGROUND

Medical students demonstrate higher rates of substance use than other university students and the general population. The challenges imposed by the coronavirus disease 2019 (COVID-19) pandemic raised significant concerns about mental health and substance use.

OBJECTIVES

Assess the current prevalence of substance use among medical students at the University of São Paulo and evaluate the impact of the COVID-19 pandemic on drug consumption.

DESIGN AND SETTING

A cross-sectional study was conducted on 275 medical students from the University of São Paulo Medical School (São Paulo, Brazil) in August 2020.

METHODS

Substance use (lifetime, previous 12 months, and frequency of use before and during the COVID-19 pandemic) and socioeconomic data were assessed using an online self-administered questionnaire. Symptoms of depression were assessed using the Patient Health Questionnaire-9.

RESULTS

Alcohol was the most consumed substance in their lifetime (95.6%), followed by illicit drugs (61.1%), marijuana (60%), and tobacco (57.5%). The most commonly consumed substances in the previous year were alcohol (82.9%), illicit drugs (44.7%), marijuana (42.5%), and tobacco (36%). Students in the first two academic years consumed fewer substances than those from higher years. There was a decreasing trend in the prevalence of most substances used after the COVID-19 pandemic among sporadic users. However, frequent users maintained their drug use patterns.

CONCLUSION

The prevalence of substance use was high in this population and increased from the basic to the clinical cycle. The COVID-19 pandemic may have affected the frequency of drug use and prevalence estimates.

First-Generation Synthetic Cathinones Produce Arrhythmia in Zebrafish Eleutheroembryos: A New Approach Methodology for New Psychoactive Substances Cardiotoxicity Evaluation

The increasing number of new psychoactive substances (NPS) entering the illicit drug market, especially synthetic cathinones, as well as the risk of cardiovascular complications, is intensifying the need to quickly assess their cardiotoxic potential. The present study aims to evaluate the cardiovascular toxicity and lethality induced by first-generation synthetic cathinones (mephedrone, methylone, and MDPV) and more classical psychostimulants (cocaine and MDMA) in zebrafish embryos using a new approach methodology (NAM). Zebrafish embryos at 4 dpf were exposed to the test drugs for 24 h to identify drug lethality. Drug-induced effects on ventricular and atrial heart rate after 2 h exposure were evaluated, and video recordings were properly analyzed. All illicit drugs displayed similar 24 h LC50 values. Our results indicate that all drugs are able to induce bradycardia, arrhythmia, and atrial-ventricular block (AV block), signs of QT interval prolongation. However, only MDPV induced a different rhythmicity change depending on the chamber and was the most potent bradycardia and AV block-inducing drug compared to the other tested compounds. In summary, our results strongly suggest that the NAM presented in this study can be used for screening NPS for their cardiotoxic effect and especially for their ability to prolong the QT intervals.
