Polysubstance Use Patterns among Justice-Involved Individuals Who Use Opioids

Overdose Experiences Among a Sample of Women in Jail with Opioid Use Disorder

Background:  Previous non-fatal overdose may increase risk of overdose fatality for women reentering the community following incarceration, but pre-incarceration overdose experiences are understudied. This study describes the prevalence and correlates of non-fatal overdose prior to jail among women with opioid use disorder (OUD). Methods: Women (N = 700) were randomly selected from eight Kentucky jails, screened for OUD, and interviewed as part of the NIDA-funded Kentucky Justice Community Opioid Innovation Network (JCOIN) trial. Descriptive statistics were used to examine women's prior overdose experiences, while bivariate analyses and logistic regression were used to identify correlates of overdose in the 90 days prior to jail. Results: Analyses found that 55.4% of women had overdosed in their lifetime, and 21.4% overdosed in the 90 days prior to jail. Of those who overdosed in the 90 days prior to jail, heroin (80.7%) was the most-commonly used drug prior to overdose, 35.2% received emergency, medically-attended services post-overdose, and 92.4% were administered naloxone - primarily by acquaintances. Overdosing in the 90 days prior to jail was positively correlated with identifying as a sexual minority, being from an urban community, childhood victimization, as well as recent heroin, fentanyl, and injection drug use. Conclusions: Findings indicate that prior overdose is common among jailed women with OUD, and although naloxone was often administered, few women received medically-attended services post-overdose. Results highlight the importance of distributing naloxone to community members and women reentering the community from jail, and suggest additional research is needed to understand factors inhibiting medical care following an overdose.

Predictors of substance use disorder treatment and mutual support group participation among Black women across the criminal legal spectrum: A latent class approach

BACKGROUND

The purpose of this study includes: 1) identifying classes of substance-related needs among Black women, and 2) examining the effect of substance-related need classes and culturally-relevant factors on Black women's use of substance use disorder (SUD) treatment and mutual support groups.

METHODS

As part of a longitudinal cohort study, Black women were recruited in prison nearing release, on probation, and in the community without involvement in the criminal legal system (CLS, n=565) and followed-up at 18-months. We conducted a baseline latent class analysis of substance-related needs among Black women. Logistic regression models adjusted for culturally-relevant factors to predict the use of treatment and frequency of mutual support group participation over 18-months among Black women who use drugs.

RESULTS

Four classes by level of needs were found: low, daily marijuana use, high mental health, and high comorbidity. During the 18-month follow-up, women characterized by the high comorbidity need class and with higher scores of religious well-being were more likely to frequently participate in mutual support groups. Non-CLS-involved women were less likely to engage with both treatment and mutual support groups than women from the prison sample at 18-months.

CONCLUSIONS

This study highlights four distinct classes of substance-related needs among Black women, highlighting the complex patterns of behavior and within-racial group differences among Black women. Black women with high comorbidity needs were more likely to participate in mutual support groups, but the latent classes did not predict SUD treatment indicating other non-medical and social contextual need factors may be at play.

Patterns of polydrug use among Black Americans who misuse opioids

In the United States, opioid-related deaths involving polydrug use are now more prevalent than those involving only opioids. What often goes unnoticed is that deaths involving more than one substance are increasing more rapidly among Black Americans than Whites. Unfortunately, little research attention is paid to understanding opioid-related polydrug use patterns among Black Americans. As a result, less is known regarding which drug combinations are most common among this population and their reasons for co-using certain drugs. Therefore, the objective of this mixed methods study was to identify which substances were most commonly co-used with opioids among Black Americans, while also capturing their motives for combining opioids with other drugs. This study used data from the Florida Minority Health Study, a mixed-methods project that included online surveys (n = 303) and qualitative in-depth interviews (n = 30) of Black Americans who misuse opioids. Data collection was conducted from August 2021 to February 2022 throughout Southwest Florida. Analyses revealed that opioids were most commonly combined with alcohol, cocaine, and methamphetamine, respectively. Opioids were co-used with alcohol in an attempt to enhance the desired effect (i.e., intoxication), while stimulants and opioids were combined to counteract the undesirable side effects of the other. This study begins to answer the question of which/why substances are combined with opioids among Black Americans and should inform behavioral health interventions targeted at this population. Data on this topic are especially timely as the United States goes through the current fourth wave of the opioid crisis that is characterized by deaths due to polydrug use. These findings invite further study using nationally representative data to determine the extent to which polydrug using patterns differ across racial/ethnic groups.

Are you thinking what I'm thinking? Defining what we mean by "polysubstance use."

The rise in drug overdoses and harms associated with the use of more than one substance has led to increased use of the term "polysubstance use" among researchers, clinicians, and public health officials. However, the term retains no consistent definition across contexts. The current authors convened from disciplines including sociology, epidemiology, neuroscience, and addiction psychiatry to propose a recommended definition of polysubstance use. An iterative process considered authors' formal and informal conversations, insights from relevant symposia, talks, and conferences, as well as their own research and clinical experiences to propose the current definition. Three key concepts were identified as necessary to define polysubstance use: (1) substances involved, (2) timing, and (3) intent. Substances involved include clarifying either (1) the number and type of substances used, (2) presence of more than one substance use disorder, or (3) primary and secondary substance use. The concept of timing is recommended to use clear terms such as simultaneous, sequential, and same-day polysubstance use to describe short-term behaviors (e.g., 30-day windows). Finally, the concept of intent refers to clarifying unintentional use or exposure when possible, and greater attention to motivations of polysubstance use. These three components should be clearly defined in research on polysubstance use to improve consistency across disciplines. Consistent definitions of polysubstance use can aid in the synthesis of evidence to better address an overdose crisis that increasingly involves multiple substances.

Identifying and Treating Incarcerated Women Experiencing Substance Use Disorders: A Review

While research on substance use disorder (SUD) treatment among justice-involved populations has grown in recent years, the majority of corrections-based SUD studies have predominantly included incarcerated men or men on community supervision. This review 1) highlights special considerations for incarcerated women that may serve as facilitating factors or barriers to SUD treatment; 2) describes selected evidence-based practices for women along the cascade of care for SUD including screening and assessment, treatment and intervention strategies, and referral to services during community re-entry; and 3) discusses conclusions and implications for SUD treatment for incarcerated women.

The impact of COVID-19 on opioid toxicity deaths for people who experience incarceration compared to the general population in Ontario: A whole population data linkage study

BACKGROUND

To inform preparedness and population health action, we need to understand the effects of COVID-19 on health inequities. In this study, we assess the impact of COVID-19 on opioid toxicity deaths among people who experience incarceration compared to others in the general population in Ontario, Canada.

METHODS

We conducted a retrospective cohort study for the period of January 1, 2015 to December 31, 2020. We accessed and linked coronial data on all opioid toxicity deaths in Ontario with correctional data for people aged 18 years and older who were incarcerated in a provincial correctional facility. We used data from the Statistics Canada Census to calculate whole population rates. We used an interrupted time series design and segmented regression to assess for change in the level or rate of increase in deaths due to opioid toxicity coinciding with the COVID-19 pandemic. We compared the impact of COVID-19 on the opioid toxicity death rates for people exposed and not exposed to incarceration.

RESULTS

Rates of opioid toxicity death increased with a linear positive slope in both persons exposed to incarceration and those not exposed over the study period. The start of COVID-19 measures coincided with a marked upward shift in the trend lines with modification of the effect of COVID-19 by both sex and exposure to incarceration. For persons exposed to incarceration, the risk ratio (RR) was 1.50 (95%CI 1.35-1.69) for males and 1.21 (95%CI 1.06-1.42) for females, and for persons not exposed to incarceration, the RR was 1.25 (95%CI 1.13-1.38) for males and not significant for females.

CONCLUSIONS

COVID-19 substantially exacerbated the risk of opioid toxicity death, impacting males and females who experienced incarceration more than those who had not, with an immediate stepwise increase in risk but no change in the rate of increase of risk over time. Public health work, including pandemic preparedness, should consider the specific needs and circumstances of people who experience incarceration.

The role of polysubstance use on criminal justice involvement in the United States

PURPOSE OF REVIEW

Polysubstance use, broadly defined as using more than one type of substance, disproportionately impacts those involved in the criminal justice system (CJS). This review synthesizes recent findings on polysubstance use among those involved in the CJS and highlights areas of particular concern and interventions.

RECENT FINDINGS

We use 18 recent articles to identify the prevalence and types of criminal justice involvement and correlates of polysubstance use and criminal justice involvement. We highlight latent patterns of polysubstance use among various criminal justice populations (adults, pregnant women, and youth) and differential associations with adverse substance use and criminal justice outcomes. Lastly, we discuss substance use treatment in the justice system, the role of polysubstance use in treatment access and outcomes, and substance use-related services for previously incarcerated individuals reentering society.

SUMMARY

Current research provides further evidence of the syndemic nature of polysubstance use, criminal justice involvement, and adverse outcomes, which are complicated by significant barriers to accessing evidence-based treatment in justice settings. Yet, current research is limited due to methodological inconsistency and limited focus on the social determinants of health, racial/ethnic disparities, and interventions to increase treatment and reentry services.

Towards more accurate classification of risk of arrest among offenders on community supervision: An application of machine learning versus logistic regression

BACKGROUND

Although there is general consensus about the behavioural, clinical and sociodemographic variables that are risk factors for reoffending, optimal statistical modelling of these variables is less clear. Machine learning techniques offer an approach that may provide greater accuracy than traditional methods.

AIM

To compare the performance of advanced machine learning techniques (classification trees and random forests) to logistic regression in classifying correlates of rearrest among adult probationers and parolees in the United States.

METHOD

Data were from the subgroup of people on probation or parole who had taken part in the National Survey on Drug Use and Health for the years 2015-2019. We compared the performance of logistic regression, classification trees and random forests, using receiver operating characteristic curves, to examine the correlates of arrest within the past 12 months.

RESULTS

We found that machine learning techniques, specifically random forests, possessed significantly greater accuracy than logistic regression in classifying correlates of arrest.

CONCLUSIONS

Our findings suggest the potential for enhanced risk classification. The next step would be to develop applications for criminal justice and clinical practice to inform better support and management strategies for former offenders in the community.

Patterns of polysubstance use and clinical comorbidity among persons seeking substance use treatment: An observational study

INTRODUCTION

Polysubstance use is common among individuals seeking treatment for substance use disorders (SUD). However, we know less about patterns and correlates of polysubstance use among treatment-seeking populations. The current study aimed to identify latent patterns of polysubstance use and associated risk factors in persons entering SUD treatment.

METHODS

Patients (N = 28,526) being admitted for substance use treatment reported on their use of thirteen substances (e.g., alcohol, cannabis, cocaine, amphetamines, methamphetamines, other stimulants, heroin, other opioids, benzodiazepines, inhalants, synthetics, hallucinogens, and club drugs) in the month before treatment and prior to the month before treatment. Latent class analysis (LCA) determined the relationship between class membership and gender, age, employment status, unstable housing, self-harm, overdose, past treatment, depression, generalized anxiety disorder, and/or post-traumatic stress disorder (PTSD).

RESULTS

Identified classes included: 1) Alcohol primary, 2) Moderate probability of past-month alcohol, cannabis, and/or opioid use; 3) Alcohol primary, Lifetime cannabis and cocaine use; 4) Opioid primary, Lifetime use of alcohol, cannabis, hallucinogens, club drugs, amphetamines, and cocaine; 5) Moderate probability of past-month alcohol, cannabis, and/or opioid use, Lifetime use of various substances; 6) Alcohol and cannabis primary, Lifetime use of various substances; and 7) High past-month polysubstance use. Individuals who engaged in past-month polysubstance use attended to face elevated risk of screening positive for recent unstable housing, unemployment, depression, anxiety, PTSD, self-harm, and overdose.

CONCLUSIONS

Current polysubstance use is associated with significant clinical complexity. Tailored treatments that reduce harms resulting from polysubstance use and related psychiatric comorbidity may improve treatment outcomes in this population.

Patterns and contexts of polysubstance use among young and older adults who are involved in the criminal legal system and use opioids: A mixed methods study

INTRODUCTION

Opioid prevention and treatment programs tailored to young adults involved in the criminal legal system are rare. We examined profiles of polysubstance use among younger and older adults involved in the criminal legal system who use opioids, and explored their experiences and motivations related to substance use. Information gleaned can inform the adaptation of existing programs and the development of novel approaches for young adults in the criminal legal system.

METHODS

Using a sequential mixed methods design we 1) quantitatively identified typologies of polysubstance users among adults aged 18-24 (n = 92) and those age 25 and over (n = 27) involved in the criminal legal system who use opioids, using latent class analysis and 2) qualitatively explored differences in personal motivations, cultural influences, and psychosocial contexts of substance use by class.

RESULTS

Our quantitative results supported a three-class typology: the majority of participants were in Class I (73 %, n = 87) and reported using primarily alcohol and marijuana. Participants in Classes II (15 %, n = 18) and III (12 %, n = 14) endorsed distinct and complicated polysubstance use profiles. Further, participants in Classes I and III were significantly younger than those in Class II. Qualitative analysis allowed us to understand associations between patterns of use, motivations, and contexts among young and older adults, comparing across classes.

CONCLUSIONS

Our results highlight the importance of attending to the needs of subpopulations based on age and use patterns to adapt and develop targeted treatment and prevention programs for high-risk adults involved in the criminal legal system.

Association of Opioid and Stimulant Use Disorder Diagnoses With Fatal and Nonfatal Overdose Among People With a History of Incarceration

IMPORTANCE

Studies have suggested a rise in opioid- and stimulant-involved overdoses in recent years in North America. This risk may be acute for individuals who have had contact with the criminal justice system, who are particularly vulnerable to overdose risk.

OBJECTIVE

To examine the association of opioid and/or stimulant use disorder diagnoses with overdose (fatal and nonfatal) among people with histories of incarceration.

DESIGN, SETTING, AND PARTICIPANTS

In this cohort study, population-based health and corrections data were retrieved from the British Columbia Provincial Overdose Cohort, which contains a 20% random sample of residents of British Columbia. The analysis included all people in the 20% random sample who had a history of incarceration between January 1, 2010, and December 31, 2014. Outcomes were derived from 5-years of follow-up data (January 1, 2015, to December 31, 2019). Statistical analysis took place from January 2022 to June 2022.

EXPOSURES

Substance use disorder diagnosis type (ie, opioid use disorder, stimulant use disorder, both, or neither), sociodemographic, health, and incarceration characteristics.

MAIN OUTCOMES AND MEASURES

Hazard ratios (HRs) are reported from an Andersen-Gill model for recurrent nonfatal overdose events and from a Fine and Gray competing risk model for fatal overdose events.

RESULTS

The study identified 6816 people (5980 male [87.7%]; 2820 aged <30 years [41.4%]) with histories of incarceration. Of these, 293 (4.3%) had opioid use disorder only, 395 (6.8%) had stimulant use disorder only, and 281 (4.1%) had both diagnoses. During follow-up, 1655 people experienced 4026 overdoses including 3781 (93.9%) nonfatal overdoses, and 245 (6.1%) fatal overdoses. In adjusted analyses, the hazard of both fatal (HR, 2.39; 95% CI, 1.48-3.86) and nonfatal (HR, 2.45; 95% CI, 1.94-3.11) overdose was highest in the group with both opioid and stimulant use disorder diagnoses.

CONCLUSIONS AND RELEVANCE

This cohort study of people with a history of incarceration found an elevated hazard of fatal and nonfatal overdose among people with both opioid and stimulant use disorder diagnoses. This study suggests an urgent need to address the service needs of individuals who have had contact with the criminal justice system and who co-use opioids and stimulants.

Types of criminal legal system exposure and polysubstance use: Prevalence and correlates among U.S. adults in the National Survey on Drug Use and Health, 2015-2019

INTRODUCTION

Criminal legal system (CLS) exposed adults experience higher rates of substance use, substance use disorder (SUD), and overdose. As most CLS exposed adults are not incarcerated, it is important to focus on CLS exposure across the carceral continuum.

METHODS

This research used pooled data from adult respondents (N = 206,314) in the National Survey on Drug Use and Health (2015-2019). Survey weighted descriptive statistics and Poisson regression were used to estimate prevalence of polysubstance use (i.e., concurrent use) across CLS exposure types (i.e., arrest, probation, parole), identifying relevant correlates.

RESULTS

The prevalence of polysubstance use was higher among CLS exposed adults, and nearly two-thirds of CLS exposed adults who used multiple types of substances indicated having an SUD. Comparing CLS exposure types, polysubstance use was less likely among adults on probation (IRR=0.89, 95%CI=0.84,0.94) or parole (IRR=0.82, 95%CI=0.76,0.87) compared to those arrested. Polysubstance use was also more likely among adults on probation (IRR=1.09, 95%CI =1.01,1.17) compared to those on parole. While some characteristics (i.e., age, ethnicity, SUD) were consistently associated with polysubstance use across types of CLS exposure, other characteristics (i.e., sexual identity, marital status, suicidal ideation) were not.

CONCLUSIONS

There is heterogeneity in health risks as a function of CLS exposure type. Further research is needed to identify causal mechanisms and differences based on demographic characteristics. Given high levels of polysubstance use across CLS exposure types, a shift towards a more comprehensive approach in substance use epidemiology may facilitate building an evidence-base to maximize treatment related interventions to reduce polysubstance-involved overdoses.

A Scoping Review of Gender, Sex and Sexuality Differences in Polysubstance Use in Adolescents and Adults

BACKGROUND

Polysubstance use is a common, problematic behavior that increases risk of harm to self and others. Research suggests that rates may vary based on gender, sex and sexuality. Understanding the current state of this literature may inform prevention and treatment of polysubstance use, leading to reduced public health burden.

OBJECTIVES

This review aimed to synthesize research on gender, sex and sexuality differences in polysubstance use in adults and adolescents.

METHODS

A scoping review was conducted using all EBSCO databases, PubMed and Google Scholar to identify articles examining the effects of gender, sex and sexuality on polysubstance use. Polysubstance use was defined broadly as the use of any combination of substances over any time period and included licit (alcohol, tobacco) and illicit substances, concurrent and simultaneous use, from lifetime to daily use and use at any frequency. Studies were considered if they were published in peer-reviewed journals between January 1990 and October 2020 and were written in English. Publicly available data sources were also utilized to fully capture prevalence data that has not been published elsewhere.

RESULTS

Findings were mostly inconsistent and often conflicting. Only two findings were generally consistent: adult men were overall more likely to report polysubstance use than adult women, and sexual and gender minorities report more frequent polysubstance use than non-minorities.

CONCLUSIONS

Research has been unable to clearly elucidate differences in polysubstance use prevalence and patterns according to gender, sex and sexuality. Several recommendations are offered to advance future research and address limitations of current research.

Polysubstance use and re-incarceration in the 12-months after release from jail: a latent transition analysis of rural Appalachian women

BACKGROUND

Rural areas have high rates of opioid and stimulant involved polysubstance use which are known to contribute to overdose. Justice-involved women are likely to have multiple substance use disorders and are particularly vulnerable in rural areas where treatment is limited.

OBJECTIVES

The research had three aims to (1) identify the patterns of polysubstance use of rural Appalachian justice-involved women, (2) examine how women's engagement in polysubstance use changed in the 12-months following initial release from jail, and (3) determine if women's changes in substance use patterns were associated with re-incarceration during the 12-months of post-release follow-up.

METHODS

A total of 339 women with recent substance use histories were randomly recruited from three rural jails. Latent transition analysis of women's substance use from baseline (in jail) to 6 and 12-months was examined, including the effect of re-incarceration on transitions (changes in substance use patterns).

RESULTS

Three latent classes were found: High Polysubstance/injection drug use (IDU) (36.3% baseline), Opioid/Benzo (Benzodiazepine) Involved Polysubstance Use (57.3% baseline), and Low Use (6.4% baseline). Polysubstance use classes were characterized by use of opioids and benzodiazepines; the High Polysubstance/IDU class was distinct in co-use and injection use of methamphetamine. Post-release, women transitioned to latent classes of reduced substance use and/or reduced injection drug use, particularly in the first six months. Women who were re-incarcerated during follow-up were likely to remain engaged in, or transition to, the High Polysubstance/IDU class (ORs: 3.14-46.56).

CONCLUSION

Justice-involved women in Appalachia reported risky polysubstance use. The first six-months post-release were a critical period for changes in substance use.

Patterns and motivations of polysubstance use: a rapid review of the qualitative evidence

INTRODUCTION

Polysubstance use-the use of substances at the same time or close in time-is a common practice among people who use drugs. The recent rise in mortality and overdose associated with polysubstance use makes understanding current motivations underlying this pattern critical. The objective of this review was to synthesize current knowledge of the reasons for combining substances in a single defined episode of drug use.

METHODS

We conducted a rapid review of the literature to identify empirical studies describing patterns and/or motivations for polysubstance use. Included studies were published between 2010 and 2021 and identified using MEDLINE, Embase, PsycINFO and Google Scholar.

RESULTS

We included 13 qualitative or mixed-method studies in our analysis. Substances were combined sequentially to alleviate withdrawal symptoms or prolong a state of euphoria ("high"). Simultaneous use was motivated by an intention to counteract or balance the effect(s) of a substance with those of another, enhance a high or reduce overall use, and to mimic the effect of another unavailable or more expensive substance. Self-medication for a pre-existing condition was also the intention behind sequential or simultaneous use.

CONCLUSION

Polysubstance use is often motivated by a desire to improve the experience based on expected effects of combinations. A better understanding of the reasons underlying substance combination are needed to mitigate the impact of the current overdose crisis.

Pre-incarceration polysubstance use involving opioids: A unique risk factor of postrelease return to substance use

OBJECTIVE

Justice-involved populations are at increased risk of overdose following release from prison and jail. This risk is exacerbated by polysubstance use, including the use of opioids with other substances. This study explored pre-incarceration polysubstance use involving opioids as a unique risk factor for postrelease return to substance use.

METHODS

The study examined data from a cohort of 501 justice-involved persons who were enrolled in a therapeutic community treatment program while incarcerated. Latent profile validation identified profiles of polysubstance use involving opioids prior to incarceration. Multivariate logistic regression examined return to substance use, defined as self-reported relapse, and a time series model examined time in the community until a relapse event occurred.

RESULTS

A latent profile validation found six unique polysubstance opioid patterns prior to incarceration. Two of these profiles, primarily alcohol and primarily buprenorphine, were at increased and accelerated risk for relapse postrelease relative to a less polysubstance use profile. Both profiles at increased risk had pre-incarceration co-use of marijuana (≈45% of month) and nonmedical use of opioids (≈40% of month) but were unique in their respective near daily use of alcohol and nonmedical buprenorphine.

CONCLUSIONS

Among persons who use opioids returning to the community, return to substance use occurs along a continuum of risk. Providers' consideration of polysubstance use patterns during treatment may assist in mitigating adverse outcomes for patients postrelease.

Profiles of lifetime substance use are differentiated by substance of choice, affective motivations for use, and childhood maltreatment

To develop personalized interventions and improve outcomes in substance-using populations, research is needed on the heterogeneity in substance use patterns and motivations that exists among adult substance users. This study took a person-centered approach to identify profiles of lifetime substance use and discern the psychosocial differences among them. To survey a spectrum of drug use severity, 1106 adults (43.4% women) were recruited from forensic and community samples. Participants reported on the frequency of lifetime substance use across multiple drug categories (sedatives, stimulants, marijuana, heroin, hallucinogens, misuse of prescription drugs) and alcohol use. Latent profile analysis was used to identify distinct profiles of substance use that were then compared on potential risk and maintenance factors for substance use. Four profiles of lifetime substance use emerged that diverged on severity of use and degree of mono vs. polysubstance use (Recreational Marijuana Use, Heavy Multidrug Intoxication, Heavy Marijuana Use, and Heavy Opioid and Polysubstance Use). The profiles differed on affective motivations for substance use (e.g., using to cope vs. using to seek a thrill), age of use onset, drug-related functional impairment, and experiences of childhood maltreatment. Cognitive functioning did not differentiate the heavy substance use profiles. Results provide compelling initial evidence that lifetime patterns of use can be used to identify groups of substance users with distinct risk and maintenance factors. Results highlight affective motivations for substance use and maltreatment history as potential treatment targets and underscore the importance of studying polysubstance use in the context of the opioid epidemic.
