Enhancing translation: A need to leverage complex preclinical models of addictive drugs to accelerate substance use treatment options. Pharmacol Biochem Behav 2024; 243:173836. [PMID: 39067531 PMCID: PMC11344688 DOI: 10.1016/j.pbb.2024.173836] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/12/2024] [Revised: 07/11/2024] [Accepted: 07/22/2024] [Indexed: 07/30/2024]
Abstract
Preclinical models of addictive drugs have been developed for decades to model aspects of the clinical experience in substance use disorders (SUDs). These include passive exposure as well as volitional intake models across addictive drugs and have been utilized to also measure withdrawal symptomatology and potential neurobehavioral mechanisms underlying relapse to drug seeking or taking. There are a number of Food and Drug Administration (FDA)-approved medications for SUDs, however, many demonstrate low clinical efficacy as well as potential sex differences, and we also note gaps in the continuum of care for certain aspects of clinical experiences in individuals who use drugs. In this review, we provide a comprehensive update on both frequently utilized and novel behavioral models of addiction with a focus on translational value to the clinical experience and highlight the need for preclinical research to follow epidemiological trends in drug use patterns to stay abreast of clinical treatment needs. We then note areas in which models could be improved to enhance the medications development pipeline through efforts to enhance translation of preclinical models. Next, we describe neuroscience efforts that can be leveraged to identify novel biological mechanisms to enhance medications development efforts for SUDs, focusing specifically on advances in brain transcriptomics approaches that can provide comprehensive screening and identification of novel targets. Together, the confluence of this review demonstrates the need for careful selection of behavioral models and methodological parameters that better approximate the clinical experience combined with cutting edge neuroscience techniques to advance the medications development pipeline for SUDs.

Abstract
Using data from Proyecto SALTO, a 15-year follow-up study of a cohort of Mexican American women in a low-income community in San Antonio, Texas, this study examines emerging patterns of current methamphetamine (MA) use, including opioid co-use, among this understudied population. A bivariate analysis compared individuals with and without current MA use and identified sociodemographic correlates and co-occurring mental health and substance use. A secondary analysis compared those with current MA use, opioid use, and concurrent MA and opioid use. Nineteen percent of the sample had current MA use. MA use was associated with having a lower income (OR = 7.04-1.93, SE = 1.59-5.46), residential instability (OR = 5.19, SE = 1.99), and suicidal ideation (OR = 2.62, SE = 0.93). Participants with MA use had more than four times the odds of using opioids than those without MA use. Women with concurrent MA and opioid use differed in sociodemographics and behavioral risks compared to those with only MA or only opioid use. These findings explore the social, mental health, and structural inequities that exacerbate risks and harms associated with high-risk substance use among marginalized Latino populations. Prevention and intervention strategies should adopt a holistic approach that considers and addresses polysubstance use, mental health, and the sociocultural contexts in which individuals live.

Harm Reduct J 2024; 21:119. [PMID: 38890736 PMCID: PMC11186154 DOI: 10.1186/s12954-024-01038-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Accepted: 06/14/2024] [Indexed: 06/20/2024] Open
Abstract
BACKGROUND The current fourth wave of the United States opioid overdose epidemic is characterized by the co-use of opioids and stimulants, including illicit opioids and methamphetamine. The co-use of these two drugs, known as "goofballing," is associated with higher risk for several adverse outcomes, including more frequent injections, greater health risks, and higher morbidity. Considering these differences, this unique subpopulation of people who inject drugs (PWID) may also have unique unmet needs and harm reduction preferences. METHODS We collected self-reported data from participants (N = 50) of a syringe services program (SSP), including basic needs and harm reduction preferences. Using bivariate analyses, we examined differences between SSP participants who do and do not co-use illicit opioids and methamphetamine. Co-use was defined as reporting the use of both drugs, which may or may not have been used simultaneously. RESULTS In the overall sample, the mean level of need was highest for bus passes or other transportation, a person who can help you get the services you need, medication for opioid use disorder, and a job or job training. Additionally, all participants reported being either interested or very interested in fentanyl test strips, safe consumption sites, delivery of syringe service supplies, and delivery of naloxone. Those who endorsed co-use had a greater need for food, healthcare, substance use disorder treatment, a support person to help them access needed services, and bus passes or transportation. CONCLUSIONS Unmet needs were prevalent, and the desire for more harm reduction services was high among these PWID. Results also suggest people who co-use illicit opioids and methamphetamine may have the greatest unmet needs and desire for additional harm reduction services.

Abstract
BACKGROUND The incidence of combination methamphetamine (METH)-opioid overdose has substantially increased in recent years. While agitation is uncommon after the naloxone (NLX) reversal of opioids, it is a major clinical concern in acute METH intoxication and can be physiologically antagonized by opioid-induced sedation. This study aimed to perform initial preclinical analysis of the safety and efficacy of dexmedetomidine (DEXMED) co-administered with NLX to attenuate METH-induced locomotor activity, as a rat model of agitation, after the reversal of fentanyl (FENT)-induced sedation. METHODS Male Sprague Dawley rats were administered subcutaneous (SC) 0.1mg/kg FENT ± 1mg/kg METH. Fifteen min later, SC 0.1mg/kg NLX ± an increasing (0, 0.032, 0.056, and 0.1mg/kg) DEXMED dose was administered prior to the measurement of locomotor activity. After a washout period, the FENT ± METH and NLX ± DEXMED administration with the highest dose of DEXMED was administered for measurement of blood oxygen saturation and heart rate. RESULTS After the NLX reversal of FENT-induced sedation, adjunct DEXMED substantially and significantly reduced METH-induced locomotor activity (p<0.05) at all doses tested. While the addition of DEXMED did not significantly reduce blood oxygenation in METH treated rats, it did so in the absence of METH. Also, DEXMED significantly reduced heart rate compared to non-DEXMED treated groups and resulted in further significant reductions in the animals not exposed to METH (p<0.05). CONCLUSIONS These data provide preclinical evidence that DEXMED may be a safe and effective chemical restraint for METH-induced agitation after NLX opioid reversal.

Prevalence of comorbid substance use disorders among people with opioid use disorder: A systematic review & meta-analysis. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2024; 128:104434. [PMID: 38677160 DOI: 10.1016/j.drugpo.2024.104434] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Revised: 04/11/2024] [Accepted: 04/19/2024] [Indexed: 04/29/2024]
Abstract
BACKGROUND Comorbid substance use disorders (SUDs) among people with opioid use disorder (OUD) contribute to poor clinical outcomes, including overdose and mortality. We present the first systematic review and meta-analysis to estimate the prevalence of specific non-opioid SUDs among people with OUD. METHODS We searched Embase, PsycINFO, and MEDLINE from 1990 to 2022 for studies that used Diagnostic and Statistical Manual of Mental Disorders (DSM) or International Classification of Diseases (ICD) criteria to assess the prevalence of non-opioid SUDs among individuals with OUD. We used random-effects meta-analyses with 95% Confidence Intervals (CIs) to pool current and lifetime prevalence estimates separately. Meta-regressions and stratified meta-analyses were used to examine differences in prevalence estimates by sample characteristics and methodological factors. RESULTS Of the 36,971 publications identified, we included data from 194 studies and 77,212 participants with OUD. The prevalence of any comorbid SUD among people with OUD was 59.5% (95%CI 49.1-69.5%) for current non-opioid SUDs, with 72.0% (95%CI 52.5-87.9%) experiencing a comorbid SUD in their lifetime. Of the studies that examined current comorbid SUDs, cocaine use disorder (30.5%, 95%CI 23.0-38.7%) was most common, followed by alcohol (27.1%, 95%CI 24.4- 30.0%), cannabis (22.7%, 95%CI 19.0-26.6%), sedative (16.1%, 95%CI 13.1-19.3%), and methamphetamine (11.4%, 95%CI 6.8-17.1%) use disorders. Substantial heterogeneity (I2>90%) across estimates was observed. Substantial heterogeneity (I2>90%) was observed across estimates, with significant variations in prevalence identified across geographic locations, recruitment settings, and other study-level factors. CONCLUSION Findings from this study emphasize the importance of comorbid SUD treatment access for people with OUD. Our estimates can inform the provision of treatment and harm reduction strategies for people with OUD and specific subpopulations.

Leveraging pooled medical examiner records to surveil complex and emerging patterns of polysubstance use in the United States. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2024:104397.

Abstract
BACKGROUND The United States (US) is an extreme global outlier for drug-related death rates. However, data describing drug-related deaths are generally available only on an 8-13-month lag. Furthermore, granular details about substance-involvement are often not available, which particularly stymies efforts to track fatal polysubstance and novel psychoactive substance use. Detailed medical examiner records provide a powerful source of information for drug-related death surveillance, but have been underutilized. METHODS We pooled medical examiner data from five US states and 14 counties that together comprise 18% of the US population to examine demographic, geographic, and drug-specific trends in polysubstance drug-related deaths. We employed mixed effects logistic regression to identify demographic factors associated with polysubstance rather than single substance drug-related deaths. We assessed the correlations between drug classes and described geographic variation in the prevalence of specific drugs and the presence of novel and emerging psychoactive substances. RESULTS Our sample included 73,077 drug-related deaths from 2012 through early 2022. Nearly two-thirds of drug-related deaths were polysubstance-involved, with the number and percentage growing annually. High percentages of polysubstance drug-related deaths were observed in both urban and rural jurisdictions. After adjusting for year and jurisdiction, female, American Indian and Alaska Native, and White individuals had the most elevated odds of polysubstance drug-related deaths. Drug-related deaths involving benzodiazepines or opioids, whether pharmaceutical or illicit, and other pharmaceutical drugs were most likely to have polysubstance involvement, while methamphetamine-involved deaths were least likely to involve multiple substances. Strong correlations were observed between prescription opioids and prescription benzodiazepines, fentanyl and xylazine, and designer benzodiazepines and novel synthetic opioids. CONCLUSIONS Analysis of detailed medical examiner records reveals the breadth and complexity of polysubstance drug-related deaths in the US. Future efforts to use this unique resource can improve population-based surveillance of drug-related deaths to better tailor interventions and solutions to this critical health crisis.

Abstract
BACKGROUND Smoking unregulated drugs has increased substantially in British Columbia. Intersecting with the ongoing overdose crisis, drug smoking-related overdose fatalities have correspondingly surged. However, little is known about the experiences of overdose among people who smoke drugs accessing the toxic drug supply. This study explores perceptions and experiences of overdose among people who smoke drugs. METHODS We conducted interviews with 31 people who smoke drugs. Interviews covered a range of topics including overdose experience. Thematic analysis was used to identify themes related to participant perceptions and experiences of smoking-related overdose. RESULTS Some participants perceived smoking drugs to pose lower overdose risk relative to injecting drugs. Participants reported smoking-related overdose experiences, including from underestimating the potency of drugs, the cross-contamination of stimulants with opioids, and responding to smoking-related overdose events. CONCLUSIONS Findings highlight the impact the unpredictable, unregulated, and toxic drug supply is having on people who smoke drugs, both among people who use opioids, and among those who primarily use stimulants. Efforts to address smoking-related overdose could benefit from expanding supervised smoking sites, working with people who use drugs to disseminate accurate knowledge around smoking-related overdose risk, and offering a smokable alternative to the unpredictable drug supply.

Abstract
BACKGROUND In recent years, stimulant use has increased among persons who use opioids in the rural U.S., leading to high rates of overdose and death. We sought to understand motivations and contexts for stimulant use among persons who use opioids in a large, geographically diverse sample of persons who use drugs (PWUD) in the rural settings. METHODS We conducted semi-structured individual interviews with PWUD at 8 U.S. sites spanning 10 states and 65 counties. Content areas included general substance use, injection drug use, changes in drug use, and harm reduction practices. We used an iterative open-coding process to comprehensively itemize and categorize content shared by participants related to concurrent use. RESULTS We interviewed 349 PWUD (64% male, mean age 36). Of those discussing current use of stimulants in the context of opioid use (n = 137, 39%), the stimulant most used was methamphetamine (78%) followed by cocaine/crack (26%). Motivations for co-use included: 1) change in drug markets and cost considerations; 2) recreational goals, e.g., seeking stronger effects after heightened opioid tolerance; 3) practical goals, such as a desire to balance or alleviate the effects of the other drug, including the use of stimulants to avoid/reverse opioid overdose, and/or control symptoms of opioid withdrawal; and 4) functional goals, such as being simultaneously energized and pain-free in order to remain productive for employment. CONCLUSION In a rural U.S. cohort of PWUD, use of both stimulants and opioids was highly prevalent. Reasons for dual use found in the rural context compared to urban studies included changes in drug availability, functional/productivity goals, and the use of methamphetamine to offset opioid overdose. Education efforts and harm reduction services and treatment, such as access to naloxone, fentanyl test strips, and accessible drug treatment for combined opioid and stimulant use, are urgently needed in the rural U.S. to reduce overdose and other adverse outcomes.

Abstract
BACKGROUND Methamphetamine overdose can cause severe psychological and physical health issues including psychosis, heart attack, and death. People who use methamphetamine (PWUM) who experience methamphetamine overdose symptoms (MOS) are advised to seek emergency healthcare; however, factors related to seeking care are not well characterized. METHODS This study used data from the 2021 Washington State Syringe Services Program (SSP) Health Survey, a cross-sectional survey administered to participants at 21 SSPs in Washington (N = 955). Participants answered questions related to substance use including emergency department/room (ER) utilization for methamphetamine use and whether they experienced psychological and physical MOS. Using Poisson regression, we assessed the association between ER utilization for methamphetamine use, non-fatal opioid overdose, and other key covariates among PWUM who experienced MOS. RESULTS Methamphetamine use in the last three months was reported by 86% of participants. Among PWUM, 31% reported psychological MOS, 19% reported physical MOS, and 37% reported ≥1 MOS in the prior three months. Non-fatal opioid overdose (adjusted prevalence ratio [APR] = 2.04, 95% CI = 1.38-3.03), main drug of goofball (heroin and methamphetamine combined) (APR = 1.98, 95% CI = 1.34-2.92) and recent blood infection/sepsis (APR = 2.07, 95% CI = 1.24-3.46) were associated with ER utilization for MOS. CONCLUSION Among people who use SSPs in Washington State, methamphetamine use remains high, and MOS are common. Recent non-fatal opioid overdose was positively associated with ER utilization for methamphetamine use among PWUM who experienced MOS. Patients in the ER for MOS should be screened for opioid use disorder and linked with harm reduction supplies like naloxone and medications for opioid use disorder.

Internalized stigma is a barrier to substance use treatment, which is greater for women and populations with criminal justice involvement. METHODS Using a nationally representative sample of adults in the United States from a probability-based survey on household opinions in 2021, we examined characteristics of women (n = 289) and men (n = 416) who misuse opioids. In gender-stratified multivariable linear regression, we investigated factors associated with internalized stigma, and tested for the interaction of stimulant use and criminal justice involvement. RESULTS Compared to men, women reported greater mental health symptom severity (3.2 vs. 2.7 on a 1 to 6 scale, p < 0.001). Internalized stigma was similar between women (2.3 ± 1.1) and men (2.2 ± 0.1). Among women and not men, however, stimulant use was positively associated with internalized stigma (0.36, 95% CI [0.07, 0.65]; p = 0.02). Interaction between stimulant use and criminal justice involvement was negatively associated with internalized stigma among women (- 0.60, 95% CI [- 1.16, -0.04]; p = 0.04); among men, the interaction was not significant. Predictive margins illustrate among women, stimulant use eliminated the gap in internalized stigma such that women with no criminal justice involvement had a similar level of internalized stigma as women with criminal justice involvement. CONCLUSION Internalized stigma between women and men who misuse opioids differed based on stimulant use and criminal justice involvement. Future research should assess whether internalized stigma influences treatment utilization among women with criminal justice involvement.

Abstract
INTRODUCTION Methadone ameliorates opioid withdrawal among hospitalized patients with opioid use disorder (OUD). To continue methadone after hospital discharge, patients must enroll in an opioid treatment program (OTP) per federal regulations. Uncontrolled opioid withdrawal is a barrier to linkage from hospital to OTP. AIM Describe a federally compliant In-Hospital Methadone Enrollment Team (IN-MEET) that enrolls hospitalized patients with OUD into an OTP with facilitated hospital to OTP linkage. SETTING Seven hundred-bed university hospital in Aurora, CO. PROGRAM DESCRIPTION A physician dually affiliated with a hospital's addiction consultation service and a community OTP completes an in-hospital, face-to-face medical assessment required by federal law and titrates methadone to comfort. An OTP-affiliated nurse with hospital privileges completes a psychosocial evaluation and provides case management by arranging transportation and providing weekly telephone check-ins. PROGRAM EVALUATION METRICS IN-MEET enrollments completed, hospital to OTP linkage, and descriptive characteristics of patients who completed IN-MEET enrollments compared to patients who completed community OTP enrollments. RESULTS Between April 2019 and April 2023, our team completed 165 IN-MEET enrollments. Among a subset of 73 IN-MEET patients, 56 (76.7%) presented to the OTP following hospital discharge. Compared to community OTP enrolled patients (n = 1687), a higher percentage of IN-MEET patients were older (39.7 years, standard deviation [SD] 11.2 years vs. 36.1 years, SD 10.6 years) and were unhoused (n = 43, 58.9% vs. n = 199, 11.8%). Compared to community OTP enrolled patients, a higher percentage of IN-MEET patients reported heroin or fentanyl as their primary substance (n = 53, 72.6% vs. n = 677, 40.1%), reported methamphetamine as their secondary substance (n = 27, 37.0% vs. n = 380, 22.5%), and reported they injected their primary substance (n = 46, 63.0% vs. n = 478, 28.3%). CONCLUSION IN-MEET facilitates hospital to OTP linkage among a vulnerable population. This model has the potential to improve methadone access for hospitalized patients who may not otherwise seek out treatment.

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

THE INTERNATIONAL JOURNAL OF DRUG POLICY 2023:104272. [PMID: 38057247 DOI: 10.1016/j.drugpo.2023.104272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 10/27/2023] [Accepted: 11/16/2023] [Indexed: 12/08/2023]
Abstract
BACKGROUND Naloxone distribution has been implemented as an essential opioid overdose prevention measure for people who inject drugs (PWID), and many jurisdictions in the United States have implemented policy change to increase naloxone access. This project describes temporal trends in and correlates of naloxone possession and use among PWID in the Seattle area of Washington State. METHODS Using a repeat cross-sectional design, we utilized two sets of serial cross-sectional surveys of PWID, which included biennial surveys of Seattle area syringe service program (SSP) clients and community-based National HIV Behavioral Surveillance surveys of PWID (NHBS-PWID) conducted from 2012-2019. Survey participant characteristics were descriptively compared between participants reporting naloxone possession to those not reporting naloxone possession. Multivariable Poisson regression was used to calculate prevalence ratios for naloxone possession comparing later to earlier survey years, adjusting for age, gender, race/ethnicity, primary drug, and experiencing and witnessing an overdose in the past 12 months. RESULTS Naloxone possession and use increased in both survey populations. The prevalence of possessing naloxone was 2.8 times greater [2019 vs. 2013= 95% CI: 2.40-3.33] among SSP participants and 2.8 times greater [2018 vs. 2012=95% CI: 2.41-3.16] among NHBS-PWID participants for the most recent time period. The prevalence of naloxone use was 1.3 times greater [2019 vs. 2017= 95% CI: 1.13-1.58] and 2.1 times greater [2015 vs. 2012=95% CI:1.62-2.73] among SSP and NHBS-PWID participants, respectively, for the most recent time period. CONCLUSION Naloxone possession and use increased in PWID in the Seattle area from 2012-2019, and is, at least in part, likely the result of numerous policy and programmatic efforts to facilitate easier naloxone accessibility in the wake of dramatic increases in overdose mortality. Further research on disparities in naloxone possession are needed to ensure equitable access.

Abstract
BACKGROUND Overdose deaths involving stimulants and opioids simultaneously have raised the specter of widespread contamination of the stimulant supply with fentanyl. METHODS We quantified prevalence of fentanyl in street methamphetamine and cocaine, stratified by crystalline texture, analyzing samples sent voluntarily to a public mail-in drug checking service (May 2021-June 2023). Samples from 77 harm reduction programs and clinics originated in 25 US states. Sample donors reported expected drug and physical descriptions. Substances were identified by gas chromatography-mass spectrometry. Negative binomial models were used to calculate fentanyl prevalence, adjusting for potential confounders related to sample selection. We also examined if xylazine changed donors' accuracy of detecting fentanyl. RESULTS We analyzed 718 lab-confirmed samples of methamphetamine (64%) and cocaine (36%). The adjusted prevalence of fentanyl was 12.5% (95% CI: 2.2%, 22.9%) in powder methamphetamine and 14.8% (2.3%, 27.2%) in powder cocaine, with notable geographic variation. Crystalline forms of both methamphetamine (Chisq=57, p<0.001) and cocaine (Chisq=18, p<0.001) were less likely to contain fentanyl: less than 1% of crystal methamphetamine (2/276) and no crack cocaine (0/53). Heroin was present in 6.6% of powder cocaine samples. Xylazine reduced donors' ability to detect fentanyl, with correct classification dropping from 92% to 42%. CONCLUSIONS Fentanyl was detected primarily in powder forms of methamphetamine and cocaine. Recommended interventions include expanding community-based drug checking, naloxone and fentanyl test strip distribution for people who use stimulants , and supervised drug consumption sites. New strategies to dampen variability in street drug composition are needed to reduce inadvertent fentanyl exposure.

Abstract
The global rise in methamphetamine use and its negative effects warrants the need for research exploring harm reduction and treatment interventions for individuals with methamphetamine use disorder. Agonist medications have been utilized for years for the treatment of heroin and opioid addiction, but have yet to be incorporated into mainstream Canadian practice for methamphetamine dependence. This review aims to provide an overview of the current trends of prescription psychostimulant usage for individuals with methamphetamine use disorder from a Canadian perspective, identifies the barriers to accessing prescription psychostimulants for methamphetamine use disorder and highlights the nursing clinical practice implications in caring for individuals with the disorder. Discourse on the sustained abstinence and harm reduction debate is presented from the perspective of methamphetamine abuse is provided along with the neuropsychiatric complications of chronic methamphetamine use. The impacts of specific prescription psychostimulants on cognition are discussed as is the use of neuroimaging techniques to assess neuronal damage in methamphetamine users. Sign of toxicity, overdose and the contraindications for use of these prescription psychostimulants is also presented. The implications to nursing clinical practice in caring for this population is provided, touching on the clinical presentation of methamphetamine use, completing thorough assessment and screening and patient education. The findings of this review indicate the need for further research in this area exploring the benefits of prescription psychostimulants as a harm reduction and treatment intervention for the global problem of methamphetamine dependence.

Abstract
BACKGROUND Amphetamine injection is expanding in North America and has been associated with male homosexuality among people who inject drugs (PWID). Applying subcultural evolution theory, we examined overall and gender-stratified trends in amphetamine injection and assessed sexual orientation as a gender-specific predictor of initiation among PWID in Montreal, Canada. METHODS Data were from HEPCO, an open prospective cohort of PWID. Gender and sexual orientation were self-identified at enrolment. Interviewer-administered questionnaires at three-monthly (HCV RNA-negative participants) or yearly (RNA-positive) intervals captured past three-month amphetamine injection and covariates. Annual prevalence and linear trends in amphetamine injection were estimated using GEE. Incidence was computed among naïve individuals and hazard ratios for initiation estimated using gender-stratified, time-varying Cox regression models. RESULTS 803 participants contributed 8096 observations between March 2011 and December 2019. Annual prevalence of amphetamine injecting increased from 3.25% [95%CI: 2.06-4.43%] to 12.7% [9.50-16.0] (trend p<0.001). Bivariate Cox regression models suggested similar and divergent predictors of initiation by gender. Incidence was 3.27 per 100 person-years [95%CI: 2.51-4.18] among heterosexual men, 7.18 [3.50-13.2] among gay/bisexual men, 1.93 [0.78-4.02] among heterosexual women and 5.30 [1.69-12.8] among gay/bisexual women. Among men, gay/bisexual identity doubled risk of initiation after adjusting for age, ethnicity, calendar year (aHR 2.16 [1.07-4.36]) and additional covariates (2.56 [1.24-5.30]). Among women, evidence for an association with gay/bisexual identity was inconclusive (aHR 2.63 [0.62-11.2]) and sample size precluded further adjustment CONCLUSIONS: Prevalence of amphetamine injection among PWID increased four-fold from 2011 to 2019, with elevated risk of initiation in gay and bisexual men.

Abstract
BACKGROUND An emerging public health threat of methamphetamine/opioid co-use is occurring in North America, including increases in overdoses related to concomitant methamphetamine/opioid use. This presents a potential risk to established treatments for opioid use disorder (i.e., medications for opioid use disorder [MOUD]). To date, few studies have examined the impact of methamphetamine use on MOUD-related outcomes, and no studies have synthesized data on MOUD retention. METHODS A scoping review was undertaken to examine the impact of methamphetamine use on MOUD retention. All original published research articles were searched in Embase, MEDLINE, PsychINFO, CINAHL, Scopus, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews and Cochrane Protocols, and Google scholar databases. Data were extracted into a standardized data extraction chart. Findings were presented narratively. RESULTS All eight included studies demonstrated an increased likelihood of treatment discontinuation or dropout among patients enrolled in MOUD who used methamphetamine. The frequency of methamphetamine use was also associated with MOUD dropout, in that those who used methamphetamine more often were more likely to discontinue MOUD. The definitions and measurements of MOUD retention varied considerably, as did the magnitude of effect size. CONCLUSIONS Results indicate that methamphetamine use has an undesirable impact on MOUD retention and results in an increased risk of treatment discontinuation or dropout. Strategies to identify concurrent methamphetamine use among individuals engaging in MOUD and educate them on the increased risk for dropout should be undertaken. Further research is needed to understand how MOUD retention among patients with concomitant opioid and methamphetamine use can be improved.

Abstract
Introduction Although methamphetamine use is rising in the United States, its impacts on patient outcomes among persons undergoing treatment for opioid use disorder (OUD) remain unclear. This study aims to assess the association between baseline methamphetamine/amphetamine (MA/A) use and subsequent illicit opioid use among patients with OUD initiating buprenorphine in an office-based setting. Methods We conducted a secondary analysis of a pilot randomized controlled trial of a behavioral mobile health intervention for buprenorphine adherence conducted over a 12-week study period at two clinic sites. The study defined baseline MA/A use by a positive urine drug test (UDT) and/or self-report of use within the past 30-days. Separate Poisson regression models with robust standard errors evaluated associations between MA/A and: i) illicit opioid use measured by weekly UDT (primary) and ii) self-reported past 30-day use at end of study (secondary). Other secondary outcomes included buprenorphine positive UDTs throughout the study and retention in OUD treatment at both weeks 12 and 24 post-randomization. Results At baseline, 28 (36%) of the 78 participants had MA/A use and use was associated with a statistically significant increase in risk of testing positive for illicit opioids on UDT during the study follow-up period (adjusted relative risk (aRR)=1.54; 95% CI=1.09-2.17; p=0.015), as well as an increased risk for reported past 30-day illicit opioid use at week 12 (aRR=3.86; 95% CI=1.47-10.18; P=0.006). The study found no significant associations between MA/A use and buprenorphine positive UDT or retention in OUD treatment. Conclusions In this sample of patients initiating buprenorphine, methamphetamine/amphetamine use at baseline was associated with illicit opioid use over a 12-week period. These findings demonstrate how co-use of methamphetamine can impede attainment of ideal OUD treatment outcomes.

Abstract
INTRODUCTION Baseline stimulant urinalysis (UA) is one of the most reliable predictors of stimulant use disorder treatment outcomes. Yet we know little about the role of baseline stimulant UA mediating the effects of different baseline characteristics on treatment outcomes. OBJECTIVES This study aimed to explore the potential mediating role of baseline stimulant UA results on the relationship between baseline characteristics and total number of stimulant negative UAs submitted during treatment. METHODS The study team conducted analyses on data from a multisite randomized clinical trial of contingency management (CM) targeting stimulant use among individuals enrolled in methadone maintenance treatment programs (n = 394). Baseline characteristics included trial arm, education, race, sex, age, and Addiction Severity Index (ASI) composite measures. Baseline stimulant UA was the mediator and total number of stimulant negative UAs provided during treatment was the primary outcome variable. RESULTS The baseline characteristics of sex (OR = 1.85), ASI drug (OR = 0.01) and psychiatric (OR = 6.20) composites were directly associated with the baseline stimulant UA result (p < 0.05 for all). Baseline stimulant UA result (B = -8.24), trial arm (B = -2.55), ASI drug composite (B = -8.38) and education (B = -1.95) were directly associated with the total number of negative UAs submitted (p < 0.05 for all). The evaluation of indirect effects of baseline characteristics on the primary outcome through baseline stimulant UA revealed significant mediated effects for the ASI drug composite (B = -5.50) and age (B = -0.05; p < 0.05 for both). CONCLUSIONS Baseline stimulant UA is a strong predictor of stimulant use treatment outcomes and mediates the association of some baseline characteristics and a stimulant use treatment outcome.

Longitudinal changes in co-involved drugs, comorbidities, and demographics of methamphetamine-related deaths in Los Angeles County. JOURNAL OF SUBSTANCE USE AND ADDICTION TREATMENT 2023; 151:209101. [PMID: 37315796 PMCID: PMC10623547 DOI: 10.1016/j.josat.2023.209101] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Revised: 06/01/2023] [Accepted: 06/04/2023] [Indexed: 06/16/2023]
Abstract
INTRODUCTION We conducted a population-based observational study of all medical examiner cases in Los Angeles County from January 2012 through June 2021 in which methamphetamine was listed as a cause of or contributing factor to death (n = 6125). We aimed to characterize demographics, comorbidities, and co-involved substances in methamphetamine-related deaths longitudinally in Los Angeles County, California. METHODS We used detailed death record data to manually classify fatalities by involvement of each organ system, opioids, alcohol, cocaine, other drugs or medications, and external/traumatic causes. Primary outcomes included: the number of methamphetamine-involved deaths, demographics of decedents, percentage of methamphetamine deaths also involving other drugs, and percentage of methamphetamine deaths involving different organ systems. We performed Mann Kendall tests of trends to identify statistically significant longitudinal changes. RESULTS During the study period, the percentage of methamphetamine-related deaths involving opioids significantly increased from 16 % in 2012 to 54 % in 2021 (p < 0.001). Concurrently, the percentage involving cardiovascular causes significantly decreased from 47 % to 26 % (p < 0.05). Methamphetamine-related deaths in LAC increasingly affected people experiencing homelessness, for whom the percentage tripled from 13 % in 2012 to 35 % in 2021. The share of decedents under 40 years old increased from 33 % to 41 %. The percentage of Black or African American decedents increased over five-fold from 3 % to 17 %. CONCLUSIONS Methamphetamine-related deaths involving opioids more than tripled in Los Angeles County from 2012 to 2021, reflecting the drug supply's shift to illicit fentanyl. More than a quarter involved cardiovascular causes. These findings have implications for treatment and prevention, including scaling up contingency management, distributing naloxone to people who primarily use stimulants, and including cardiovascular care alongside these interventions directly targeted to reduce harms of methamphetamine use.

Abstract
BACKGROUND Opioid and methamphetamine co-use is increasing across the USA with overdoses involving these drugs also rising. West Virginia (WV) has led the US in opioid overdose death rates since at least 2013 and rising co-use of methamphetamine with opioids has played a greater role in deaths over the last 5 years. METHODS This study used rapid ethnography to examine methods and motivations behind opioids and methamphetamine co-use from the viewpoint of their consumers. Participants (n = 30) were people who injected heroin/fentanyl also using methamphetamine who participated in semi-structured interviews. RESULTS We found multiple methods of co-using opioids and methamphetamine, whether alternately or simultaneously and in varying order. Most prioritized opioids, with motives for using methamphetamine forming three thematic categories: 'intrinsic use', encompassing both inherent pleasure of combined use greater than using both drugs separately or for self-medication of particular conditions; 'opioid assisting use' in which methamphetamine helped people manage their existing heroin/fentanyl use; and 'reluctant or indifferent use' for social participation, reflecting methamphetamine's low cost and easy availability. CONCLUSIONS Methamphetamine serves multiple functions among people using opioids in WV. Beliefs persist that methamphetamine can play a role in preventing and reversing opioid overdose, including some arguments for sequential use being protective of overdose. 'Reluctant' uptake attests to methamphetamine's social use and the influence of supply. The impact on overdose risk of the many varied co-use patterns needs further investigation.

Abstract
Food insecurity (FI) impacts people with HIV (PWH) and those who use substances (i.e. drugs and alcohol). We evaluated the longitudinal association between FI and HIV transmission risks (unprotected sexual contacts and shared needles/syringes). Among 351 PWH who use substances in Russia, 51.6% reported FI and 37.0% past month injection drug use. The mean number of unprotected sexual contacts in the past 90 days was 13.4 (SD 30.1); 9.7% reported sharing needles/syringes in the past month. We did not find a significant association between mild/moderate FI (adjusted IRR = 0.87, 95% CI 0.47, 1.61) or severe FI (aIRR = 0.84, 95% CI 0.46, 1.54; global p = 0.85) and unprotected sexual contacts. We observed a significant association between severe FI and sharing needles/syringes in the past month (adjusted OR = 3.27, 95% CI 1.45, 7.39; p = 0.004), but not between mild/moderate FI and sharing needles/syringes in the past month (aOR = 1.40,95% CI 0.58, 3.38; p = 0.45). These findings suggest that severe FI could be a potential target for interventions to lower HIV transmission.

Abstract
Background For people who inject drugs (PWID), housing instability due to decreasing housing affordability and other factors (e.g., loss of housing due to severed relational ties, evictions due to drug use) results in added pressure on an already vulnerable population. Research has shown that housing instability is associated with overdose risk among PWID. However, the construct of housing instability has often been operationalized as a single dimension (e.g., housing type, homelessness, transience). We propose a multi-dimensional measure of housing instability risk and examine its association with drug overdose to promote a more holistic examination of housing status as a predictor of overdose. Methods The baseline data from a network-based, longitudinal study of young PWID and their networks living in metropolitan Chicago, Illinois was analyzed to examine the relationship between a housing instability risk index-consisting of five dichotomous variables assessing housing instability-and lifetime overdose count using negative binomial regression. Results We found a significant positive association between the housing instability risk score and lifetime overdose count after adjusting for 12 variables. Conclusions Our results support the practical utility of a multi-dimensional measure of housing instability risk in predicting overdose and highlight the importance of taking a holistic approach to addressing housing instability when designing interventions.

Abstract
Background Drug use route transition interventions promote safer consumption by facilitating a switch from injection to safer routes such as smoking or oral consumption. Methods We performed a descriptive analysis using data from questions about "free, clean equipment for smoking" heroin, methamphetamine and/or crack from the Seattle 2018 National HIV Behavioral Surveillance survey of people who inject drugs (N = 555). We estimated the proportion of respondents with access to free safer smoking equipment, and among these participants, the proportion who reported that this access reduced their injection frequency. Among respondents without access to free safer smoking equipment, we described the proportion who were interested in getting access, and whether they thought this access would reduce their injection frequency. Results Among participants who reported prior year heroin (n = 495), methamphetamine (n = 372), or crack (n = 88) injection, 11%, 11% and 12% reported access to free safer smoking equipment, respectively. Of those with access, the proportion that reported that access reduced their injection frequency ranged from 12% to 44%. Among participants without access, 28% who used heroin, 45% who used methamphetamine, and 49% who used crack were interested in access. Of interested participants, a majority reported that they thought this access would reduce their frequency of injection. Conclusions Access to free safer smoking equipment was limited. Many participants were interested in getting free safer smoking equipment and reported that this access may reduce their injection frequency. Safer smoking equipment is a harm reduction strategy that should be available to reduce risks from opioid and stimulant injection.

Abstract
INTRODUCTION Methadone maintenance therapy (MMT) has been a pillar of opioid addiction treatment. Opioid treatment programs (OTPs) have been faced with an escalating threat of stimulant use and related overdose deaths among patients. We know little about how providers currently address stimulant use while maintaining treatment for opioid use disorder. METHODS We conducted 5 focus groups with 36 providers (n = 11 prescribers; 25 behavioral health staff), and collected an additional 46 surveys (n = 7 prescribers; 12 administrators; 27 behavioral health staff). Questions focused on perceptions of patient stimulant use and interventions. We applied inductive analysis to identify themes relevant to identification of stimulant use, use trends, intervention approaches, and perceived needs to improve care. RESULTS Providers indicated a trend of rising stimulant use among patients, especially those experiencing homelessness or comorbid health conditions. They reported a range of approaches to patient screening and intervention, including medication and harm reduction, improving treatment engagement, increasing level of care, and providing incentives. Providers expressed less agreement as to which of these interventions were effective, and though providers saw stimulant use as a common and severe problem, they reported little problem recognition and interest in treatment from their patients. A particular concern of providers was the prevalence and danger of synthetic opioids, such as fentanyl. They sought more research and resources to identify effective interventions and medications to address these issues. Also notable was an interest in contingency management (CM) and use of reinforcements/rewards to encourage stimulant use reduction. CONCLUSION Providers face challenges in treating patients who use both opioids and stimulants. Although methadone is available to treat opioid use, no such "silver bullet" exists for stimulant use disorder. The rise in stimulant and synthetic opioid (e.g., fentanyl) combination products is presenting an extraordinary challenge for providers whose patients are at unprecedented risk for overdose. Providing OTPs with more resources to address polysubstance use is critical. Existing research indicates strong support for CM in OTPs, but providers reported regulatory and financial barriers to implementation. Further research should develop effective interventions that are accessible to providers in OTPs.

Abstract
INTRODUCTION Sharing injecting equipment is a major route of transmission for blood borne viruses such as hepatitis C and HIV. Although needle and syringe programs are widely available throughout metropolitan Australia, rates of sharing equipment have not significantly changed in recent years. This study aimed to identify factors associated with recent equipment sharing among people who inject drugs in Australia. METHODS A paper-based survey was distributed via peer-based organisations between June and November 2018 and was completed by 603 participants. Survey questions addressed recent injecting experiences, equipment sharing, community attachment, stigma and wellbeing. Participants who had recently shared injecting equipment were compared with those who had not shared any equipment using multivariable logistic regression. RESULTS Recent equipment sharing was associated with recent heroin use, experiencing any past-year stigma related to injecting drug use, and higher levels of attachment to a community of people who inject drugs. An interaction effect showed increased community attachment was associated with increased odds of sharing equipment among young participants, but with decreased odds of sharing equipment among older participants. DISCUSSION AND CONCLUSIONS Community networks of people who inject drugs can play important roles in harm reduction initiatives. While being connected with a community of people who inject drugs increased the odds of sharing injecting equipment, this community connection also increases opportunities for social support, sharing information and mitigating the negative effects of stigma. Collaboratively and meaningfully engaging with communities of people who inject drugs has the potential to increase the reach and effectiveness of health promotion services.

Abstract
Over three decades of evidence indicate that dopamine (DA) D3 receptors (D3R) are involved in the control of drug-seeking behavior and may play an important role in the pathophysiology of substance use disorders (SUD). The expectation that a selective D3R antagonist/partial agonist would be efficacious for the treatment of SUD is based on the following key observations. First, D3R are distributed in strategic areas belonging to the mesolimbic DA system such as the ventral striatum, midbrain, and ventral pallidum, which have been associated with behaviors controlled by the presentation of drug-associated cues. Second, repeated exposure to drugs of abuse produces neuroadaptations in the D3R system. Third, the synthesis and characterization of highly potent and selective D3R antagonists/partial agonists have further strengthened the role of the D3R in SUD. Based on extensive preclinical and preliminary clinical evidence, the D3R shows promise as a target for the development of pharmacotherapies for SUD as reflected by their potential to (1) regulate the motivation to self-administer drugs and (2) disrupt the responsiveness to drug-associated stimuli that play a key role in reinstatement of drug-seeking behavior triggered by re-exposure to the drug itself, drug-associated environmental cues, or stress. The availability of PET ligands to assess clinically relevant receptor occupancy by selective D3R antagonists/partial agonists, the definition of reliable dosing, and the prospect of using human laboratory models may further guide the design of clinical proof of concept studies. Pivotal clinical trials for more rapid progression of this target toward regulatory approval are urgently required. Finally, the discovery that highly selective D3R antagonists, such as R-VK4-116 and R-VK4-40, do not adversely affect peripheral biometrics or cardiovascular effects alone or in the presence of oxycodone or cocaine suggests that this class of drugs has great potential in safely treating psychostimulant and/or opioid use disorders.

INQUIRY : A JOURNAL OF MEDICAL CARE ORGANIZATION, PROVISION AND FINANCING 2023; 60:469580231206608. [PMID: 37902428 PMCID: PMC10617300 DOI: 10.1177/00469580231206608] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/03/2023] [Revised: 09/07/2023] [Accepted: 09/21/2023] [Indexed: 10/31/2023]
Abstract
Cross-border activities are possibly associated with the use of amphetamine-type stimulants (ATS), this study was to explore poly-substance of ATS use and influencing factors among ATS use populations in southwest China. A cross-sectional study was conducted by response driven and continuous samplings from January to July 2021. Descriptive, univariate and logistic regression were carried out. ATS users accounted for 95.6% of the target population, of whom one-third had cross-border experiences with 4.1% of the cross-border purchase of drugs. ATS users were mainly over 31 years old (53.9%), male (98.7%), minority (79.1%), and unmarried (72.7%). Cross-border users consumed more ketamine (8%) and methamphetamine (40%) (P < .05). After adjusting for socioeconomic-demographic factors, cross-border activity [OR: 0.336 (0.141, 0.799)], occupation [OR: 0.273 (0.080, 0.929)], injecting drug behavior [OR: 6.239 (1. 087, 35.811)], frequency [OR: 0.251 (0.073, 0.859)], and ATS use location [OR: 2.915 (1.040, 8.168)] were possible factors influencing ATS use patterns (P < .05). Cross-border activity may be associated with polydrug use, especially predominantly methamphetamine use, among ATS users along the Southwest border. It implied that the focus of drug prevention and control in border areas should be on cross-border populations.

Abstract
BACKGROUND Prior research indicates rising methamphetamine use and harms in the U.S., potentially related to increases in methamphetamine injection. To date, research on trends and correlates of methamphetamine injection is limited. METHODS Analysis of trends and correlates of methamphetamine injection among treatment admissions among persons aged ≥ 12 whose primary substance of use at admission is methamphetamine. Data are from the Treatment Episode Data Set. Analyses includes descriptive statistics, trend analyses, and multilevel multivariable logistic regression. RESULTS Primary methamphetamine treatment admissions increased from 138,379 in 2010 to 201,021 in 2019. Among primary methamphetamine admissions, injection as the usual route of use increased from 24,821 (18.0 % of admissions) in 2010 to 55,951 (28.2 % of admissions) in 2019. Characteristics associated with increased adjusted odds of reporting methamphetamine injection included: males (aOR = 1.13, 95 % CI = 1.10-1.15); admission age 25-34 years (aOR = 1.23, 95 % CI = 1.19-1.28) and 35-44 years (aOR = 1.12, 95 % CI = 1.08-1.17) compared to age 18-24; dependent living (aOR = 1.33, 95 % CI = 1.29-1.37) and homelessness (aOR = 1.58, 95 % CI = 1.54-1.63) compared to independent living; part-time employment (aOR = 1.08, 95 % CI = 1.02-1.14), unemployment (aOR = 1.39, 95 % CI = 1.34-1.44) and not in labor force (aOR = 1.43, 95 % CI = 1.37-1.49) compared to full-time employment; one to ≥ four prior treatment admissions (aORs ranging from 1.19 to 1.94) compared to no prior admissions; also reporting use of cocaine (aOR = 1.10, 95 % CI = 1.05-1.16), heroin (aOR = 3.52, 95 % CI = 3.40-3.66), prescription opioids (aOR = 1.61, 95 % CI = 1.54-1.67), or benzodiazepines (aOR = 1.42, 95 % CI = 1.32-1.52) at treatment admission. CONCLUSIONS Findings lend further evidence to a resurgence of methamphetamine use that is intertwined with the ongoing opioid crisis in the U.S. Efforts to expand evidence-based prevention, treatment, and response efforts, particularly to populations at highest risk, are urgently needed.

Abstract
BACKGROUND Crystal methamphetamine use has substantially increased among people who use opioids in recent years, yet the impact of opioid agonist therapy (OAT) on crystal methamphetamine use remains poorly characterized. Therefore, we sought to examine the relationship between OAT engagement and crystal methamphetamine use and to assess if this relationship differs according to the ongoing use of unregulated opioids. METHODS Data was collected from two harmonized ongoing prospective cohorts of people who use drugs in Vancouver, Canada, between December 2005 and March 2020. We employed multivariable generalized estimating equations to study the relationship between OAT engagement and crystal meth use stratified by ongoing unregulated opioid use. RESULTS Of 1742 participants who reported frequent opioid use at baseline, the median age was 42 years, and 61.3% were male. Multivariable analyses showed that compared to those who had not received OAT for at least one year: in the absence of ongoing unregulated opioid use, individuals who recently discontinued (adjusted Odds Ratio [aOR] = 0.47, 95% CI = 0.27-0.79), newly initiated (aOR = 0.52, 95% CI = 0.31-0.89), or were retained on OAT (aOR = 0.48, 95% CI = 0.31-0.72) reported a lower frequency of crystal methamphetamine use; in the presence of ongoing unregulated opioid use, individuals who newly initiated OAT reported a greater crystal methamphetamine use frequency (aOR = 1.24, 95% CI = 1.02-1.51). CONCLUSIONS We demonstrated a differential relationship between OAT engagement and crystal methamphetamine use that was conditional on the ongoing use of unregulated opioids. Our findings highlight the complexity of OAT implementation and suggest that polysubstance use patterns should be an important consideration for care providers when devising comprehensive treatment strategies and prognosticating treatment effects.

THE INTERNATIONAL JOURNAL OF DRUG POLICY 2022; 107:103791.

Abstract
BACKGROUND Polysubstance use is common among people who use drugs, including the co-use of stimulants and opioids. Research suggests the practice of simultaneous co-injection of methamphetamines and opioids, often referred to as "goofballs", is increasing. As a relatively unique drug use practice, little qualitative research currently exists on goofball injecting. This study explores the practice and embodied experiences of goofball injecting. METHODS This article draws on in-depth interviews conducted across two qualitative studies undertaken in Vancouver, Canada's Downtown Eastside neighbourhood examining changing dynamics in relation to stimulant use and experiences with an overdose prevention site-based safer supply intervention, respectively. Interviews containing discussions of goofball use (n=29) were extracted from each study and merged into a single qualitative dataset. Data were analysed thematically and focused on the practices and embodied experiences of goofball injection. RESULTS Our analysis uncovered how goofball injection represented a complex drug use practice driven by the desire to achieve particular embodied experiences not attainable by using either drug individually. We identified three distinct practices of goofball use: 1) to alter or enhance the effects of opioids; 2) to alter or enhance the effects of methamphetamines; and 3) to balance out the effects of both drugs. CONCLUSION Our study fills an important gap in the polysubstance use literature specifically exploring the co-injection of methamphetamines and opioids. Our findings highlight the need to implement and expand interventions and services attentive to polysubstance use and the role of pleasure in drug taking practices, including expanding non-medicalized opioid and stimulant safer supply initiatives across North America.

Abstract
We describe the response to detection of a time-space cluster of new HIV infection in the Portland, OR metro area among people who inject drugs (PWID) and/or people who use any form of methamphetamine. This time-space cluster took place in a region with a syndemic of homelessness and drug use. The investigation included new HIV diagnoses in 2018, 2019, and 2020 in Clackamas, Multnomah, and Washington Counties. Public health response included activating incident command, development and implementation of an enhanced interview tool, outreach testing, and stakeholder engagement. We identified 396 new cases of HIV infection, 116 (29%) of which met the cluster definition. Most cluster cases had no molecular relationships to previous cases. Persons responding to the enhanced interview tool reported behaviors associated with HIV acquisition. Field outreach testing did not identify any new HIV cases but did identify hepatitis C and syphilis infections. We show the importance of a robust public health response to a time-space cluster of new HIV infections in an urban area.

Abstract
Globally, millions of people suffer from various substance use disorders (SUD), including mono-and polydrug use of opioids and methamphetamine. Brain regions such as the cingulate cortex, infralimbic cortex, dorsal striatum, nucleus accumbens, basolateral and central amygdala have been shown to play important roles in addiction-related behavioral changes. Clinical and pre-clinical studies have characterized these brain regions and their corresponding neurochemical changes in numerous phases of drug dependence such as acute drug use, intoxication, craving, withdrawal, and relapse. At present, many studies have reported the individual effects of opioids and methamphetamine. However, little is known about their combined effects. Co-use of these drugs produces effects greater than either drug alone, where one decreases the side effects of the other, and the combination produces a prolonged intoxication period or a more desirable intoxication effect. An increasing number of studies have associated polydrug abuse with poorer treatment outcomes, drug-related deaths, and more severe psychopathologies. To date, the pharmacological treatment efficacy for polydrug abuse is vague, and still at the experimental stage. This present review discusses the human and animal behavioral, neuroanatomical, and neurochemical changes underlying both morphine and methamphetamine dependence separately, as well as its combination. This narrative review also delineates the recent advances in the pharmacotherapy of mono- and poly drug-use of opioids and methamphetamine at clinical and preclinical stages.

Abstract
Introduction Methamphetamine use and methamphetamine-involved deaths have increased dramatically since 2015, and opioid-related deaths now frequently involve methamphetamine. Nevada and New Mexico are states with elevated rates of opioid and methamphetamine use. In this paper, we report results from a qualitative analysis that examined patterns of methamphetamine and opioid co-use over participants' lifespan, factors that influence those patterns, and implications for health outcomes among users. Methods Project AMPED was a multisite, mixed-methods study of methamphetamine use in Northern New Mexico and Northern Nevada. Between December 2019 and May 2020, qualitative interview participants were asked to describe their patterns of and reasons for co-administration of opioids and methamphetamine. Results We interviewed 21 people who reported using methamphetamine in the past 3 months. Four primary patterns of methamphetamine and opioid co-use were identified: [1] using both methamphetamine and heroin, either simultaneously or sequentially (n = 12), [2] using methamphetamine along with methadone (n = 4), [3] using prescription opioids and methamphetamine (n = 1), and [4] using only methamphetamine (n = 4). Among those who used methamphetamine and heroin simultaneously or sequentially, motivations drew from a desire to enhance the effect of one drug or another, to feel the "up and down" of the "perfect ratio" of a goofball, or to mitigate unwanted effects of one or the other. Among those who used methamphetamine and methadone, motivations focused on alleviating the sedative effects of methadone. Conclusion To address the emergent trend of increasing methamphetamine-related deaths, researchers, health care professionals, and community health workers must acknowledge the decision-making processes behind co-use of opioids and methamphetamine, including the perceived benefits and harms of co-use. There is an urgent need to address underlying issues associated with drug use-related harms, and to design interventions and models of treatment that holistically address participants' concerns.

Abstract
In the United States, combined stimulant/opioid overdose mortality has risen dramatically over the last decade. These increases may particularly affect non-Hispanic Black and Hispanic populations. We used death certificate data from the US National Center for Health Statistics (2007-2019) to compare state-level trends in overdose mortality due to opioids in combination with 1) cocaine and 2) methamphetamine and other stimulants (MOS) across racial/ethnic groups (non-Hispanic White, non-Hispanic Black, Hispanic, and non-Hispanic Asian American/Pacific Islander). To avoid unstable estimates from small samples, we employed principles of small area estimation and a Bayesian hierarchical model, enabling information-sharing across groups. Black Americans experienced severe and worsening mortality due to opioids in combination with both cocaine and MOS, particularly in eastern states. Cocaine/opioid mortality increased 575% among Black people versus 184% in White people (Black, 0.60 to 4.05 per 100,000; White, 0.49 to 1.39 per 100,000). MOS/opioid mortality rose 16,200% in Black people versus 3,200% in White people (Black, 0.01 to 1.63 per 100,000; White, 0.09 to 2.97 per 100,000). Cocaine/opioid overdose mortality rose sharply among Hispanic and Asian Americans. State-group heterogeneity highlighted the importance of data disaggregation and methods to address small sample sizes. Research to understand the drivers of these trends and expanded efforts to address them are needed, particularly in minoritized groups.

[PMID: 35237191 PMCID: PMC8884160 DOI: 10.3389/fpsyt.2022.814574] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/13/2021] [Accepted: 01/19/2022] [Indexed: 11/21/2022] Open
Abstract
Concurrent use of stimulants (e.g., methamphetamine) and opioids (e.g., fentanyl) has become increasingly common in recent years and continues to pose an enormous health burden, worldwide. Despite the prevalence, relatively little is known about interactions between the reinforcing effects of stimulants and opioids in this pattern of polysubstance use. The goals of the current study were to evaluate the relative reinforcing and relapse-related effects of methamphetamine and fentanyl using a concurrent access, drug-vs.-drug choice procedure. Male Sprague-Dawley rats were first allowed to acquire self-administration for either 0.1 mg/kg/infusion methamphetamine or 0.0032 mg/kg/infusion fentanyl, independently, after which concurrent access to both drugs was provided. When training doses of methamphetamine and fentanyl were concurrently available, a subset of rats self-administered both drugs, either within a session or alternating across sessions, whereas the remaining rats responded exclusively for one drug. When the cost of the preferred drug was increased (i.e., unit dose reduced), or the cost of the non-preferred drug was decreased (i.e., unit dose increased), choice was largely allocated toward the cheaper alternative. Following extinction of responding, methamphetamine- and fentanyl-paired cues reinstated responding on both levers. Responding reinstated by a priming injection of methamphetamine or fentanyl allocated more responding to the lever previously reinforced by the priming drug. The current studies suggest that choice of methamphetamine and fentanyl is largely allocated to the cheaper alternative, although more co-use was observed than would be expected for economic substitutes. Moreover, they lay the groundwork for more fully evaluating interactions between commonly co-abused drugs (e.g., stimulants and opioids) in order to better understand the determinants of polysubstance use and develop effective treatment strategies for individuals suffering from a polysubstance use disorder.

Abstract
Recent attention has focused on the growing role of psychostimulants, such as methamphetamine in overdose deaths. Methamphetamine is an addictive and potent stimulant, and its use is associated with a range of physical and mental health harms, overdose, and mortality. Adding to the complexity of this resurgent methamphetamine threat is the reality that the increases in methamphetamine availability and harms are occurring in the midst of and intertwined with the ongoing opioid overdose crisis. Opioid involvement in psychostimulant-involved overdose deaths increased from 34.5% of overdose deaths in 2010 to 53.5% in 2019-an increase of more than 50%. This latest evolution of the nation's overdose epidemic poses novel challenges for prevention, treatment, and harm reduction. This narrative review synthesizes what is known about changing patterns of methamphetamine use with and without opioids in the United States, other characteristics associated with methamphetamine use, the contributions of the changing illicit drug supply to use patterns and overdose risk, motivations for couse of methamphetamine and opioids, and awareness of exposure to opioids via the illicit methamphetamine supply. Finally, the review summarizes illustrative community and health system strategies and research opportunities to advance prevention, treatment, and harm reduction policies, programs, and practices.

Addressing injecting related risks among people who inject both opioids and stimulants: Findings from an Australian survey of people who inject drugs. Addict Behav Rep 2022; 15:100398. [PMID: 35005190 PMCID: PMC8717740 DOI: 10.1016/j.abrep.2021.100398] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2021] [Revised: 11/18/2021] [Accepted: 12/08/2021] [Indexed: 01/04/2023] Open
Abstract
Background Opioids and stimulants are the most commonly injected illicit drugs worldwide and in Australia. While some people who inject drugs (PWID) prefer either opioids or stimulants, others regularly use both opioids and stimulants. Limited available research indicates that those who use opioids and stimulants together, either in combination or alternating between the two, may engage in injection-related practices which potentially place them at greater health risk and could lead to poorer health outcomes. Methods Participants were recruited nationally through member organizations of the Australian Injecting and Illicit Drug Users League (AIVL); these organizations represent PWID in each Australian state and territory. This study compared a sample of PWID (N = 535) who reported past-month injection of opioids only (N = 173), stimulants only (N = 208), or both (N = 154) on a range of health and wellbeing outcomes. PWID completed a survey assessing drugs injected, frequency of injecting, receptive equipment sharing, psychological distress, self-reported hepatitis C (HCV) status, experienced and internalized stigma, drug use salience, and community attachment. Results People who injected both opioids and stimulants reported more frequent injecting, more experiences of stigma, and greater reported HCV diagnosis than people who injected stimulants or opioids alone. They also showed greater attachment to a community of PWID and greater salience of drug use to their identity. Conclusions The findings of increased injecting and broader harms associated with injecting both stimulants and opioids are important for tailoring harm reduction and intervention designs for people who use both opioid and stimulant drugs, including prioritizing peer-based approaches.

Abstract
INTRODUCTION The HIV epidemic in King County, Washington has traditionally been highly concentrated among men who have sex with men, and incidence has gradually declined over 2 decades. In 2018, King County experienced a geographically concentrated outbreak of HIV among heterosexual people who inject drugs. METHODS Data sources to describe the 2018 outbreak and King County's response were partner services interview data, HIV case reports, syringe service program client surveys, hospital data, and data from a rapid needs assessment of homeless individuals and people who inject drugs. In 2020, the authors examined the impact of delays in molecular sequence analyses and cluster member size thresholds, for identifying genetically similar clusters, on the timing of outbreak identification. RESULTS In 2018, the health department identified a North Seattle cluster, growing to 30 people with related HIV infections diagnosed in 2008-2019. In total, 70% of cluster members were female, 77% were people who inject drugs, 87% were homeless, and 27% reported exchanging sex. Intervention activities included a rapid needs assessment, 2,485 HIV screening tests in a jail and other outreach settings, provision of 87,488 clean syringes in the outbreak area, and public communications. A lower cluster size threshold and more rapid receipt and analyses of data would have identified this outbreak 4-16 months earlier. CONCLUSIONS This outbreak shows the vulnerability of people who inject drugs to HIV infection, even in areas with robust syringe service programs and declining HIV epidemics. Although molecular HIV surveillance did not identify this outbreak, it may have done so with a lower threshold for defining clusters and more rapid receipt and analyses of HIV genetic sequences.

Abstract
INTRODUCTION Co-occurring heroin and methamphetamine use is a growing public health problem. This study assessed the characteristics of Medicaid patients admitted to substance use disorder (SUD) treatment programs for heroin and methamphetamine use compared with patients admitted for heroin only. METHODS The study identified patients who entered treatment for heroin and methamphetamine and those admitted for heroin only between 2014 and 2017 from the Oregon Treatment Episode Data Set linked with Medicaid enrollment, and medical and pharmacy claims. We used a cross-sectional design to compare demographics, type of treatment, and substance use characteristics between the two groups. We used logistic regression models to assess differences in the odds of opioid-related and all-cause adverse events. RESULTS Among the 3802 study sample, 2004 (53%) were admitted for both heroin and methamphetamine use. The heroin and methamphetamine group were more likely to be younger, female, White or American Indian/Alaska Native; and had more comorbidities than patients admitted for heroin only. Patients admitted for heroin and methamphetamine treatment were less likely to receive any medication for opioid use disorder (MOUD) (56% vs 75%, p < 0.001) and received fewer days of MOUD treatment (mean 188 vs. 265 days, p < 0.001) compared to the heroin only group. The heroin and methamphetamine group were more likely to receive buprenorphine (28.1% vs 24.2%) and less likely to receive methadone (39.9% vs 62.5%). The heroin and methamphetamine group began use at a younger age, used and injected more frequently than those admitted for heroin only. Patients treated for heroin and methamphetamine had 17% lower odds of OUD-related adverse events (aOR 0.83; 95% CI 0.70-0.99) and 52% higher odds of all-cause adverse events (aOR 1.52; 95% CI 1.14-2.03) relative to the heroin only group. CONCLUSION Patients admitted for both heroin and methamphetamine reported greater addiction severity (more frequent use, earlier onset of use, and injection use), yet less commonly received MOUD compared to those who were admitted for heroin only. These findings indicate substantial missed opportunities for MOUD treatment even among people who successfully engage with the SUD treatment system.

Adults With Opioid and Methamphetamine Co-use Have Lower Odds of Completing Short-Term Residential Treatment Than Other Opioid Co-use Groups: A Retrospective Health Services Study.

[PMID: 34955930 PMCID: PMC8692265 DOI: 10.3389/fpsyt.2021.784229] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2021] [Accepted: 11/15/2021] [Indexed: 12/15/2022] Open
Abstract
Objective: There is an increase in persons entering substance use treatment who co-use opioids and methamphetamines in recent years. Co-using these substances may negatively impact treatment retention in the residential setting. We explored predictors of adults completing short-term residential treatment among persons with primary opioid use disorder (OUD) who co-use either alcohol, benzodiazepines, cocaine, or methamphetamines. Methods: This study used the 2019 de-identified, publicly available Treatment Episode Dataset-Discharges. The sample included adults discharged from short-term residential treatment with primary OUD who co-used either alcohol, benzodiazepines, cocaine, or methamphetamines. The final sample size included 24,120 treatment episodes. Univariate statistics were used to describe the sample. Two logistic regression models were used to predict completing treatment. The first logistic regression model included the co-use groups as predictors and the second model added other demographic and treatment-relevant covariates. Results: A slight majority (51.4%) of the sample prematurely discharged from treatment. Compared to the other three co-use groups, the opioid and methamphetamine co-use group had the highest proportion of individuals who were women (45.0%), unemployed (62.5%), current injection drug use (76.0%), living in the Midwest (35.9%), living in the south (33.5%), and living in the west (15.5%). The opioid and methamphetamine co-use group also had the highest proportion of individuals not receiving medications for OUD (84.9%), not having a prior treatment episode (28.7%), and not completing treatment (57.4%). In the final logistic regression model, which included covariates, the opioid and alcohol (OR = 1.18, 95% CI = 1.080-1.287, p < 0.001), opioid and benzodiazepine (OR = 1.33, 95% CI = 1.213-1.455, p < 0.001), and opioid and cocaine (OR = 1.16, 95% CI = 1.075-1.240, p < 0.001) co-use groups had higher odds of completing treatment than the opioid and methamphetamine co-use group. Conclusions: Opioid and methamphetamine co-use may complicate short-term residential treatment retention. Future work should identify effective strategies to retain persons who co-use opioids and methamphetamines in treatment.
