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 The clinical profiles of methamphetamine-induced psychosis (MIP) and schizophrenia are largely overlapping making differentiation challenging. In this systematic review and meta-analysis, we aim to compare the positive and negative symptoms of MIP and schizophrenia to better understand the differences between them. STUDY DESIGN In accordance with our pre-registered protocol (CRD42021286619), we conducted a search of English-language studies up to December 16th, 2022, in PubMed, EMBASE, and PsycINFO, including stable outpatients with MIP and schizophrenia. We used the Newcastle-Ottawa Scale to measure the quality of cross-sectional, case-control, and cohort studies. STUDY RESULTS Of the 2052 articles retrieved, we included 12 studies (6 cross-sectional, 3 case-control, and 2 cohort studies) in our meta-analysis, involving 624 individuals with MIP and 524 individuals with schizophrenia. Our analysis found no significant difference in positive symptoms between the two groups (SMD, -0.01; 95%CI, -0.13 to +0.11; p = 1). However, individuals with MIP showed significantly less negative symptoms compared to those with schizophrenia (SMD, -0.35; 95CI%, -0.54 to -0.16; p = 0.01; I2 = 54 %). Our sensitivity analysis, which included only studies with a low risk of bias, did not change the results. However, our meta-analysis is limited by its cross-sectional approach, which limits the interpretation of causal associations. Furthermore, differences in population, inclusion criteria, methodology, and drug exposure impact our findings. CONCLUSIONS Negative symptoms are less prominent in individuals with MIP. While both groups do not differ regarding positive symptoms, raises the possibility of shared and partly different underlying neurobiological mechanisms related to MIP and schizophrenia.

Abstract
BACKGROUND International efforts have reduced the availability of methamphetamine precursors, but its distribution and use continue to rise. Methamphetamine use can lead to short- and long-term adverse effects, including addiction, physical and psychosocial health problems, socioeconomic troubles, incarceration, overdose, and death. Gay, bisexual, and other men who have sex with men (MSM) have been shown to have an elevated prevalence of methamphetamine use. METHODS We conducted a systematic review and meta-analysis to estimate the prevalence of methamphetamine use among MSM. We searched electronic databases, such as PubMed, for peer-reviewed literature published between 2011 and 2022. Data on methamphetamine use were extracted, including study features, location, study design, sampling method, recruitment period, specific MSM subgroups, prevalence period, and demographics. Employing a random-effects model, we computed the pooled prevalence of methamphetamine use among MSM across two prevalence periods: recent use (i.e., one month, three months, six months, one year) and lifetime use. RESULTS The systematic review included 56 studies with a total of 25,953 MSM who use methamphetamine. Most studies were conducted in Europe, with the highest prevalence reported in the United Kingdom. The studies primarily used cross-sectional or cohort study designs with convenience sampling. The pooled prevalence rates across recent use (i.e., past month, past three months, past six months, and past year) was 15% (95% CI [11-19%]). Additionally, we pooled lifetime use, which was 23% (95% CI [9-38%]). High heterogeneity (I2 > 99%) was observed, indicating significant variation. CONCLUSION This systematic review and meta-analysis provide a pooled prevalence of methamphetamine use among MSM. The analysis accounts for study design, prevalence period, specific MSM subgroups, and geographical areas to estimate methamphetamine use in diverse settings and populations. The review highlights the need for targeted interventions and harm reduction strategies focused on prevention, education, healthcare access, and stakeholder collaboration to address the multifaceted challenges of methamphetamine use among MSM.

Abstract
BACKGROUND Methamphetamine use is common among persons with opioid use disorder. This study evaluated associations between methamphetamine use and treatment with agonist medications for opioid use disorder (MOUD, specifically buprenorphine, and/or methadone) in U.S. rural communities. METHODS The Rural Opioid Initiative (ROI) is a consortium spanning 10 states and 65 rural counties that included persons who reported past 30-day use of opioids and/or injection drug use between 1/2018 and 3/2020. Analyses were restricted to participants who had ever used opioids and had data on past 30-day methamphetamine use. Multivariable models examined the relationship between methamphetamine use and utilization of agonist MOUD. RESULTS Among 2899 participants, 2179 (75.2%) also reported recent methamphetamine use. Persons with methamphetamine use compared to those without were younger, more likely to have injected drugs, be unhoused, criminal justice involved, and less likely to have health insurance. Adjusted for age, sex, race, and study site, recent methamphetamine use was associated with lower relative odds of past 30-day methadone treatment (aOR=0.66; 95% CI: 0.45-0.99) and fewer methadone treatment days (aIRR=0.76; 0.57-0.99), but not past 30-day buprenorphine receipt (aOR=0.90; 0.67-1.20), buprenorphine treatment days in past 6 months: aIRR=0.88; 0.69-1.12) or perceived inability to access buprenorphine (aOR=1.12; 0.87-1.44) or methadone (aOR=1.06; 0.76-1.48). CONCLUSION Methamphetamine use is common among persons who use opioids in rural U.S. areas and negatively associated with current treatment and retention on methadone but not buprenorphine. Future studies should examine reasons for this disparity and reduce barriers to methadone for persons who use opioids and methamphetamine.

Abstract
While much attention has been given to methamphetamine's wake-promoting properties and the concept of using methamphetamine to increase energy, little is known about the ways people who use methamphetamine manage their use to pursue their functional goals or the challenges they encounter doing so. This qualitative study explores the experiences of people who used methamphetamine to manage wakefulness and reduce sleep as a means to achieve functional goals. We conducted a grounded theory analysis of 202 anonymous letters submitted to an online forum. Five themes emerged from this process: (1) Using methamphetamine to extend wakefulness and reduce the need for sleep; (2) Losing control over wakefulness and the need for sleep; (3) Managing wakefulness and the need for sleep while on methamphetamine; (4) Getting caught in a cycle of wakefulness and sleep; and (5) Sleep disruptions even after ceasing methamphetamine use. Participants believed methamphetamine was critical to meeting their functional goals, and they went to great lengths to try to manage the substance's ill effects. Thus, clients in treatment for methamphetamine use disorder may benefit from interventions addressing their underlying motivations and perceived associations between methamphetamine and meeting functional goals.

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 Given the significant rise in methamphetamine use and related mortality in the United States, it is critical to explore differences in treatment trends with particular attention to women and ethnoracial groups in hard-hit areas like Los Angeles County. Methods We analyzed a large sample across 4 waves: 2011 (105 programs, 10 895 clients), 2013 (104 programs, 17 865 clients), 2015 (96 programs, 16 584 clients), and 2017 (82 programs, 15 388 clients). We completed a comparative analysis to identify differences across subgroups and a trend analysis of treatment episodes by gender and ethnoracial group to differentiate users of methamphetamine and users of other drugs. Results Treatment clients using methamphetamine increased over time for each gender and race. There were also significant differences across age groups. Women comprised a greater proportion of treatment episodes involving methamphetamine use (43.3%) compared to all other drugs combined (33.6%). Latinas represented 45.5% of methadone-related admissions. Compared with other drug users, methamphetamine users had a lower successful treatment completion rate and were served by programs with less financial and culturally responsive capacity. Conclusions Findings highlight a sharp increase in treatment admissions for methamphetamine users of all gender and ethnocultural groups. Women, especially Latinas, saw the most significant increases, with a widening gender gap over time. All subgroups of methamphetamine users had a lower treatment completion rate compared with users of other drugs, and critical differences existed in the programs where they received services.

Abstract
The twin opioid-stimulant epidemics have led to increased overdose deaths and present unique challenges for individuals entering treatment with opioid-stimulant polysubstance use. This study examined tonic and cue-induced craving as a primary outcome among persons in substance use treatment who reported primary substances of opioids, methamphetamine, or cocaine. The sample consisted of 1974 individuals in 55 residential substance-use treatment centers in the United States in 2021. Weekly surveys were delivered via a third-party outcomes tracking system, including measures of tonic and cue-induced craving. Initial comparisons on tonic and cue-induced craving were made among those who primarily used opioids, cocaine, or methamphetamine. Further, the effect of opioid/stimulant polysubstance use on tonic and cue-induced craving was evaluated using marginal effect regression models. Primary methamphetamine use was associated with decreased tonic craving compared to primary opioid use (β = -5.63, p < 0.001) and primary cocaine use was also associate with decreased tonic craving compared to primary opioid use (β = -6.14, p < 0.001). Primary cocaine use was also associated with lower cue-induced cravings compared to primary opioid use (β = -0.53, p = 0.037). Opioid-methamphetamine polysubstance use was associated with higher tonic craving (β = 3.81, p = <0.001) and higher cue-induced craving (β = 1.55, p = 0.001); however, this was not the case for opioid-cocaine polysubstance use. The results of this study indicate that individuals who primarily use opioids and have secondary methamphetamine use experience higher cue-induced and tonic-induced craving, suggesting that these individuals may benefit from additional interventions that target craving and mitigate relapse risk and other negative sequelae.

Abstract
BACKGROUND Identifying predictors of methamphetamine use can inform population prevention strategies. METHODS Participants (n = 1265) born in Christchurch, New Zealand were followed from birth to age 40. Methamphetamine outcomes (any use since the last interview, and regular use, defined as any period of at least weekly use) were ascertained by self-report at six interviews from age 18 to 40. Predictors with plausible associations with methamphetamine use were extracted from the study database. These were grouped into early predictors (age 0-16), comprising childhood, familial and individual characteristics; and later time-dynamic correlates of methamphetamine use in adulthood (ages 16-40). Generalised estimating equation models were fitted to identify predictors of methamphetamine use outcomes. RESULTS In adjusted models, paternal overprotectiveness and childhood anxious / withdrawn behavior were associated with any use of methamphetamine, but not regular use. Conversely, childhood conduct problems and parental illicit drug were associated with regular use but not any use. Male sex, high novelty seeking and deviant peer affiliations were associated with both any use and regular use in adjusted models. The strongest correlates of methamphetamine use in adulthood were unemployment, life stress and other substance use disorders (cannabis, nicotine, and alcohol). CONCLUSION Markers of externalizing problems in childhood and adolescence (conduct problems, high novelty seeking, parental illicit substance use, and deviant peer affiliations) are the strongest predictors of regular methamphetamine use in adulthood.

Abstract
OBJECTIVE To examine associations between frailty and drug, alcohol, and tobacco use among a large diverse cohort of people with HIV (PWH) in clinical care in the current era. METHODS PWH at 7 sites across the United States completed clinical assessments of patient-reported measures and outcomes between 2016 and 2019 as part of routine care including drug and alcohol use, smoking, and other domains. Frailty was assessed using 4 of the 5 components of the Fried frailty phenotype and PWH were categorized as not frail, pre-frail, or frail. Associations of substance use with frailty were assessed with multivariate Poisson regression. RESULTS Among 9336 PWH, 43% were not frail, 44% were prefrail, and 13% were frail. Frailty was more prevalent among women, older PWH, and those reporting current use of drugs or cigarettes. Current methamphetamine use (1.26: 95% CI 1.07-1.48), current (1.65: 95% CI 1.39-1.97) and former (1.21:95% CI 1.06-1.36) illicit opioid use, and former cocaine/crack use (1.17: 95% CI 1.01-1.35) were associated with greater risk of being frail in adjusted analyses. Current smoking was associated with a 61% higher risk of being frail vs. not frail (1.61: 95% CI 1.41-1.85) in adjusted analyses. CONCLUSIONS We found a high prevalence of prefrailty and frailty among a nationally distributed cohort of PWH in care. This study identified distinct risk factors that may be associated with frailty among PWH, many of which, such as cigarette smoking and drug use, are potentially modifiable.

Abstract
PURPOSE Little is known about co-occurring eating disorder (ED) psychopathology and methamphetamine use. Even less is known about the precise nature of how ED symptom profiles and methamphetamine use interact and influence treatment-related practices. The purpose of this study is to report a case study of a patient with co-occuring ED psychopathology and methamphetamine use. METHOD We present the case of a White woman in her mid-30s with a long history of body image-related worries and methamphetamine use. She presented for psychiatric assessment initially for methamphetamine addiction and paranoid psychotic symptom treatment, but also reported significant weight and shape concerns. RESULTS Over the duration of approximately 1 year of treatment, this patient experienced a reduction in her methamphetamine use, but an increased concern around how abstinence may portend weight gain. She reported that a return to methamphetamine use was underpinned by a drive to manage her weight. CONCLUSION With increasing evidence documenting the elevated co-occurrence of methamphetamine use and ED symptomatology, this case report highlights the potential mechanisms by which these respective psychopathologies may be exacerbate the other, rendering both increased risk of relapse, and body dissatisfaction. LEVEL OF EVIDENCE Level IV, case study.

Abstract
BACKGROUND Methamphetamine use is increasing among persons with opioid use disorder (OUD). The study aims were to describe methamphetamine/amphetamine (MA/A) use among patients treated for OUD with buprenorphine/naloxone (BUP-NX) or extended-release naltrexone (XR-NTX), and to explore associations between treatment arm and MA/A use. METHODS Secondary analysis of data from a multi-site, open-label, randomized controlled trial of XR-NTX versus BUP-NX for 24 weeks. The outcome variable was MA/A use defined by either positive urine drug toxicology or self-report. The main predictor was treatment assignment (BUP-NX v. XR-NTX). Longitudinal mixed-effects logistic regression models were fit to model the odds of MA/A use during the study. Additional predictors included study visit and baseline MA/A use. RESULTS Among the sample of 570 participants with OUD, baseline use of MA/A was observed in 105 (18.4%). There was no significant treatment effect over the study period, though BUP-NX subjects, on average, had about half the odds of MA/A use compared to XR-NTX subjects (OR=0.50; p = 0.051). In the same model, baseline MA/A use and study visit were both significantly associated with MA/A use over time. CONCLUSION In this sample of treated OUD patients, nearly a fifth of participants had MA/A use at baseline and the frequency of use did not decline over time: in fact, the odds of use slightly increased for each later visit. These secondary analyses found no significant difference in MA/A use between BUP-NX and XR-NTX treatment arms, however, the observation of less MA/A in the buprenorphine arm merits further investigation.

Abstract
Background British Columbia (BC) has been in a state of public health emergency since 2016, due to the unprecedented numbers of fatal and non-fatal drug toxicity (i.e. overdose) events. Methamphetamine detection in illicit drug toxicity deaths increased from 14% in 2012 to 43% in 2020 suggesting a concerning trend of concurrent methamphetamine and opioid use in BC, consistent with rising patterns identified across North America. People who use methamphetamine concurrently with opioids face an elevated risk of harm. This study aimed to identify behaviours for survival and wellness practiced by people who concurrently use methamphetamine and opioids. Methods One-on-one semi-structured interviews were conducted by peer research assistants in person and by telephone. Thematic analysis was carried out to identify patterns in behaviours participants described as important to their safety in the context of concurrent use of methamphetamine and opioids. Results Participants (n = 22) were distributed across the province with at least four participants from each of the five geographic health regions: 64% self-identified as men, and 50% self-identified as Indigenous. Daily methamphetamine use was reported by 72.7% of participants, and 67.3% reported using alone either often or always. Participants made several considerations and adaptations in order to balance the perceived benefits and risks of their use of methamphetamine with opioids. Two overarching themes were identified to describe how participants adapted their use for survival and wellness. The first was personal safety behaviours which included self-regulation and self-care behaviours. The second was interpersonal safety behaviours which included using alongside peers, and engaging with peer-led services (e.g. community outreach organizations) and public health-led services (e.g. overdose prevention sites) to reduce the risk of harm. Participants identified many gaps in available services to meet their diverse needs. Conclusions This manuscript identified diversity in participants’ methamphetamine and opioid use (i.e. frequency, route of administration), and a range of behaviours that were performed to improve wellness and survival while using methamphetamine and opioids. Harm reduction and treatment responses must be robust and adaptable to respond to the diversity of patterns of substance use among people who use methamphetamine and opioids concurrently, so as to not perpetuate harm and leave people behind.

Abstract
BACKGROUND Identifying solutions to the continued rise in overdose deaths is a public health priority. However, there is evidence of change in recent substance type associated with morbidity and mortality. To better understand the continued rise in overdose deaths, in particular those attributed to opioid and stimulant use disorders, increased knowledge of patterns of use is needed. METHODS Retrospective cohort study of Veterans diagnosed with an opioid or stimulant use disorder between 2005 and 2019. The outcome of interest was diagnosis of substance use disorders, specifically examining combinations of opioid and stimulant use disorders among this population. RESULTS A total of 1932,188 Veterans were diagnosed with at least one substance use disorder (SUD) during the study period, 2005 through 2019. While the annual prevalence of opioid use disorder (OUD) diagnoses increased more than 155%, OUD diagnoses absent of any other SUD diagnosis increased by an average of 6.9% (95% CI, 6.4, 7.5) per year between 2005 and 2019. Between 2011 and 2019, diagnoses of co-morbid methamphetamine use disorder (MUD) and OUD increased at a higher rate than other SUD combinations. CONCLUSIONS The prevalence of comorbid SUD, in particular co-occurring opioid and methamphetamine use disorder, increased at a higher rate than other combinations between 2005 and 2019. These findings underscore the urgent need to offer patients a combination of evidence-based treatments for each co-morbid SUD, such MOUD and contingency management for persons with comorbid opioid and methamphetamine use disorders.

Abstract
BACKGROUND We aimed to evaluate for occult systolic dysfunction and the effect of methamphetamine cessation among patients with methamphetamine use (MU) and heart failure with preserved ejection fraction (HFpEF). METHODS A retrospective cohort of patients with HFpEF with serial echocardiograms was stratified by MU and evaluated using myocardial strain analysis on echocardiograms at baseline and 1 year to measure global longitudinal strain (GLS). Contemporaneous controls with an ICD diagnosis of HF within 3 days of an MU case were chosen. RESULTS Patients with MU (n = 31) were younger (49 ± 10 vs 59 ± 16 years, p < 0.01) and more frequently male (55% vs 26%, p = 0.04) than controls (n = 23). There was no baseline difference in ejection fraction (EF) (median 66% [IQR 58,71%] vs 62% [56,69%], p = 0.33) or GLS (-13.0% [-16.3,-10.9%] vs -14.8% [-16.0,-11.3%], p = 0.40). At one-year follow-up, MU cessation (n = 15) was associated with improvement in GLS (absolute change -4.4% [-6.5,-1.7%], p < 0.01), while no absolute change was observed with continued MU (n = 16) (0.74% [-1.2,-2.8%], p = 0.22) or controls without MU (-0.6% [-2.1,2.8%], p = 0.78). Of those with abnormal baseline GLS, normalization was observed in 46% with MU cessation, none with continued MU, and 5% of controls (p < 0.001). Among MU patients, improvement in GLS was associated with decreased HF admissions per year [HR 0.74 per 1% change in GLS, 95% CI 0.55,0.98, p = 0.04]. CONCLUSIONS Patients with MU and HFpEF may have occult systolic dysfunction as demonstrated by abnormal GLS, and MU cessation at 1 year is associated with improvement in GLS and a reduction in risk of HF admissions.

Abstract
Background A high proportion of people receiving both oral and injectable opioid agonist treatment report concurrent use of stimulants (i.e. cocaine and or amphetamines), which has been associated with higher rates of continued illicit opioid use and treatment dropout. A recent randomized controlled trial demonstrated the effectiveness of dextroamphetamine (a prescribed stimulant) at reducing craving for and use of cocaine among patients receiving injectable opioid agonist treatment. Following this evidence, dextroamphetamine has been prescribed to patients with stimulant use disorder at a clinic in Vancouver. This study investigates perceptions of the effectiveness of dextroamphetamine from the perspective of these patients. Methods Data were collected using small focus groups and one-on-one interviews with patients who were currently or formerly receiving dextroamphetamine (n = 20). Thematic analysis was conducted using an iterative approach, moving between data collection and analysis to search for patterns in the data across transcripts. This process led to the defining and naming of three central themes responding to the research question. Results Participants reported a range of stimulant use types, including cocaine (n = 8), methamphetamine (n = 8), or both (n = 4). Three central themes were identified as relating to participants’ perceptions of the effectiveness of the medication: 1) achieving a substitution effect (i.e. extent to which dextroamphetamine provided a substitution for the effect they received from use of illicit stimulants); 2) Reaching a preferred dose (i.e. speed of titration and effect of the dose received); and 3) Ease of medication access (i.e. preference for take home doses (i.e. carries) vs. medication integrated into care at the clinic). Conclusion In the context of continued investigation of pharmacological treatments for stimulant use disorder, the present study has highlighted how the study of clinical outcomes could be extended to account for factors that contribute to perceptions of effectiveness from the perspective of patients. In practice, elements of treatment delivery (e.g. dosing and dispensation protocols) can be adjusted to allow for various scenarios (e.g. on site vs. take home dosing) by which dextroamphetamine and other pharmacological stimulants could be implemented to provide “effective” treatment for people with a wide range of treatment goals and needs.

Abstract
BACKGROUND The current study examined correlates of cognitive insight in people enrolled in a methamphetamine pharmacotherapy trial; whether cognitive insight at the start of the trial predicted medication adherence and reductions in methamphetamine use during the trial; and, whether insight would remain stable over the trial or improve with reductions in methamphetamine use. METHODS A subset of people enrolled in a 12-week randomised placebo-controlled pharmacotherapy trial for methamphetamine dependence completed the Beck Cognitive Insight Scale, comprising subscales for Self-Reflection and Self-Certainty, at baseline (n = 152) and at week 12 (n = 79). Medication adherence was expressed as the percentage of non-missed doses measured using eCAP™ technology. Methamphetamine use days were assessed using the Timeline Followback. RESULTS At baseline, greater Self-Reflection was correlated with more severe methamphetamine withdrawal, and hostility, whereas Self-Certainty was correlated with less education and longer duration of methamphetamine use. No relationship was found between BCIS subscales at baseline and medication adherence (Self-Reflection b[SE] = -0.73 [0.43] p = .09; Self-Certainty b[SE] = -0.31 [0.48] p = .52,). Neither BCIS subscale was predictive of reduced methamphetamine use at 12 weeks (Self-Reflection b[SE] = 0.001 [0.01] p = .95 Self-Certainty b[SE] = -0.003 [0.01], p = .74). Self-Reflection decreased over the trial (t = 3.42, p = .001) but this was unrelated to change in methamphetamine use (Self-Reflection, b[SE] = -1.68 [1.16] p = .15) Change in methamphetamine use was found to be a significant predictor of Self-Certainty at 12 weeks (b [SE] = -2.71 [1.16] p = .02). CONCLUSIONS We found no evidence that cognitive insight predicted medication adherence or methamphetamine reduction in people engaged in this trial. Ongoing or increased methamphetamine use predicted increased Self-Certainty at 12 weeks.

Abstract
Recent data indicate a resurgence of stimulant use and harms in the United States; thus, there is a need to identify risk factors to inform development of effective prevention strategies. Prior research suggests adverse childhood experiences (ACEs) are common among individuals using stimulants and may be an important target for prevention. National Epidemiological Survey on Alcohol and Related Conditions was used to estimate prevalence of ACEs among U.S. adults using amphetamine-type stimulants (ATS), cocaine, or both. Multivariable logistic regression examined associations between ACEs and stimulant use and use disorders. Among adults reporting lifetime ATS use, 22.1% had ≥4 ACEs, 24.9% had 2-3 ACEs, 22.4% had 1 ACE, 30.6% reported no ACEs. Among adults with lifetime ATS use disorder, 29.3% reported ≥4 ACEs, 28.7% reported 2-3 ACEs, 21.6% reported 1 ACE, and 20.4% reported no ACEs. Multivariable logistic regression found a significant relationship between number of ACEs and stimulant use and use disorders. In conclusion, we found a strong relationship between increasing ACE exposures and stimulant use and use disorders. Advancing comprehensive strategies to prevent ACEs and treating underlying trauma among those using stimulants holds great promise to reduce stimulant use and its health and social consequences in the United States.

Abstract
Methamphetamine (meth) use is a recurring public health challenge in the U.S. In 2016, approximately 1.6 million Americans reported using meth. Meth use is associated with a number of adverse outcomes, including those associated with users' sexual health. In particular, meth use is linked to an increased risk for sexually transmitted infections and unplanned pregnancies. While studies have examined associations between substance use of various types-including meth use, and shame and guilt-few studies have examined relationships among substance use, sexual risk behaviors, and shame and guilt. No qualitative studies, to our knowledge, have studied all three of these phenomena in a sample of meth users. The present qualitative study explored the sexual risk behaviors and associated feelings of shame and guilt in relation to meth use. It draws from anonymous letters and stories (N = 202) posted to an online discussion forum by meth users and their family members. A grounded theory analysis of these narratives identified four primary themes pertaining to meth use and sexual behaviors: (1) feeling heightened sexual arousal and stimulation on meth, (2) experiencing sexual dissatisfaction on meth, (3) responding to sexual arousal and dissatisfaction, and (4) feeling ashamed and/or guilty. Ultimately, the present findings indicate that feelings of shame and guilt may arise more from the consequences of sexual risk behaviors stemming from meth use rather than meth use itself. The emotional toll of meth-induced sexual risk behaviors, particularly shame and guilt over the loss of meaningful relationships and self-respect due to multiple sexual partners, may provide an important opportunity for interventionists.

Abstract
BACKGROUND AND AIMS There is a need for more evidence to guide efforts to address harmful methamphetamine use amongst young Aboriginal and Torres Strait Islander Australians. 'Communities that Care' (CTC) is an evidence-based process developed to prevent alcohol and other drug-related harm but its suitability for use in Aboriginal contexts has not been established. This study sought to explore whether risk and protective factors for methamphetamine use, as described by Aboriginal stakeholders, align with the CTC risk and protective factor framework. METHOD Focus groups and individual interviews were conducted in Aboriginal communities nationally. Data were analysed thematically using the CTC framework as a deductive coding framework. Additional themes were captured and summarised. RESULTS Participants were 147 (80% Aboriginal; 44% female) key stakeholders aged between 16 and 69 (median=40), recruited via organisational and community networks in each site. Relevant factors were identified in all four CTC domains: community, family, school, peer/individual. However, these four domains did not capture issues of central importance to Aboriginal people. These were summarised as an additional domain, 'Culture and Identity.' CONCLUSIONS Given that the Communities that Care risk and protective framework did not sufficiently capture issues of central importance to Aboriginal people, there is a need for different, community-informed models that reflect the unique determinants of use in this context.

Abstract
BACKGROUND Methamphetamine use, with and without opioids, has increased substantially, but little is known about the sociodemographic characteristics, substance use patterns, or health profiles of individuals who use methamphetamine. To design effective public health interventions, health care professionals and policymakers need data describing individuals who are using methamphetamine in the midst of the opioid crisis. METHODS We used 2015-2018 data from the National Survey on Drug Use and Health and included non-elderly adults aged 18-64 years. We categorized respondents into three groups: use of opioids without methamphetamine use, use of methamphetamine without opioid use, or use of both opioids and methamphetamine. Multiple logistic regression models controlling for sociodemographic factors were used to compare substance use characteristics and measures of individual health between the three groups. RESULTS People who used any methamphetamine were more likely to be unstably housed, low-income, and live in rural areas. Use of both opioids and methamphetamine was associated with a 132 % higher prevalence of injection needle use, and a nearly twofold higher prevalence of viral hepatitis compared with opioid use alone. One third of individuals reporting use of both opioids and methamphetamine had a severe mental illness, a 55 % higher prevalence than those using opioids alone. CONCLUSIONS Individuals who used opioids and methamphetamine had more complex substance use and health profiles than individuals who used opioids alone. These findings suggest public health and harm reduction approaches designed to address opioid use remain important in an era of rising methamphetamine use.

Abstract
BACKGROUND Pregnant women attending the Specialist Drug and Alcohol Service in Perth use methamphetamine as their primary drug of choice. This is the only tertiary service for pregnant and postnatal women with complex Alcohol and Other Drug Use in Western Australia. It is a midwifery-led multidisciplinary team. Many of the women struggle with addiction, polysubstance use, co-occurring mental health, family and domestic violence, complex trauma and fear of Child Protection and infant removal. Therefore, the aim of this study was to understand the impact of methamphetamine use of pregnant women attending the service and explore and highlight the potential barriers to engagement and follow-up. METHODS A qualitative study informed by phenomenological methods was undertaken using semi-structured interviews with 20 women with methamphetamine use attending the service in order to explore and understand the experience of using methamphetamine in pregnancy and the postpartum period. A thematic analysis was undertaken with data from the women in the study (n=20) to identify key themes. RESULTS Key themes that emerged from the women's experiences detail their resilience and experience with methamphetamine and the impact that methamphetamine has on their life. A key concern for women regarding methamphetamine use and engagement with specialist services was the welfare of their child(ren). Agencies charged with child protection was a barrier to treatment because women feared disclosure of methamphetamine use would result in loss of child custody. Themes highlighted the multiple layers of adversities, and trauma from childhood to adulthood including, co-occurring drug use, mental health and life histories of trauma (abuse, violence, and neglect; intergenerational trauma; intergenerational drug and alcohol use, and child removal), the omnipresence of methamphetamine, and the impact on pregnancy and mothering. CONCLUSION We conclude that understanding the experiences of women and the impact methamphetamine use has on their life is paramount to providing effective and appropriate care to support pregnant women in a trauma-informed and woman-centred approach. Poor engagement in pregnancy care for women with methamphetamine use has significant impacts on mother and infant.

Abstract
BACKGROUND Use of methamphetamines (MA) and other stimulants have consistently been associated with HIV/STI risk globally. We evaluated a community mobilization intervention (Connect to Protect, C2P®) to prevent MA use among youth and reduce HIV risk behaviors through community structural changes. DESIGN A community-randomized trial in northern Thailand with matched districts randomized to C2P intervention or a standard voluntary counseling and testing (VCT) control. Intervention districts formed stakeholders' coalitions to plan tailored local prevention programs. Two independent random household samples of youth aged 14-24 were surveyed in 2009 and 2012. Lifetime and recent MA use was modeled with multilevel logistic regression. RESULTS Intervention initiatives included family-strengthening programs, school-based programs and opening a community drug treatment center. Control communities applied the government-led "war on drugs" approach in addition to youth and family programs. Baseline (N = 1077) and follow-up (N = 1225) samples included 47.5% females and 21.7% aged ≤16. Lifetime MA use in intervention districts reduced from 13.4% to 11.7% compared to reduction from 16.2% to 10.4% in the control districts (non-significant). In models, lifetime MA use was associated with: time (aOR = 0.6, 95%CI: 0.38-0.83), females (aOR = 0.2, 95%CI: 0.15-0.29), increasing age (aOR = 2.4, 95%CI: 1.40-4.20, ages 16-19; aOR = 3.5, 95%CI: 2.00-6.12, ages ≥20), and not being full-time students (aOR = 5.3, 95%CI: 3.77-7.37). Recent MA use showed similar results. Additionally, lifetime MA use was significantly associated with alcohol use, risky sexual behaviors and elevated depressive symptoms. CONCLUSIONS Delay in developing and implementing specific prevention programs in the intervention districts slowed diffusion of the effect into the communities. Secular trends with contentious civil unrest and active drug-enforcement efforts in the control communities also contributed to the null intervention effect. Longer time and intensified efforts stressing a public health approach are needed to demonstrate the effectiveness of community mobilization in reducing substance use and HIV risk in this rural Thai community.

Abstract
Objective To present an unusual case and proposed mechanism of bilateral spontaneous pneumothoraces with pneumomediastinum in a patient with intravenous methamphetamine use. Case report Thin white man presented with confusion and chest pain after intravenous methamphetamine use. Initial workup found bilateral pneumothoraces with pneumomediastinum. Conservative management was initiated and subsequent radiographs and physical examination revealed subsequent improvement in pneumothoraces and pneumomediastinum. Conclusion Intravenous methamphetamine use increases a wide number of inflammatory markers that can increase the risk of spontaneous pneumothoraces and pneumomediastinum. In patients with known risk factors, methamphetamine use can promote an increased incidence of spontaneous pneumothorax and pneumomediastinum.

Abstract
BACKGROUND Implementation intentions are situation-linked action plans that increase health behaviors such as condom use. Few studies have measured the strength of implementation intentions, especially regarding condom use. Non-injection drug users are at high risk for HIV due to risky sexual practices. Substance use before sex may increase risky sexual behaviors, and implementation intentions are a promising, practical route for HIV prevention. PURPOSE This prospective study assessed the measurement properties of the newly developed Strength of Implementation Intentions Scale (SIIS) for condom use and investigated whether the SIIS predicted condom use one-year later. The study evaluated whether behavioral intentions and alcohol or methamphetamine use before sex modified the relationship between the SIIS and condom use. METHODS Participants were 590 non-injection drug users convicted of nonviolent drug offenses in court-mandated outpatient drug diversion programs. They completed self-directed computer assessments at baseline and at one-year follow-up. Measures included demographics, behavioral intentions to use condoms, the SIIS for condom use, alcohol and methamphetamine use before or during sex, and condom use. Psychometric properties, direct, and interaction effects of the SIIS were evaluated using structural equation modeling and general linear regressions. RESULTS The SIIS, behavioral intentions, and condom use were positively correlated and there was discriminant validity between all three constructs. In addition, the SIIS predicted condom use one-year later in this high-risk population. No significant interactions were detected. CONCLUSIONS The SIIS is predictive of condom use behavior, is psychometrically sound and distinct from behavioral intentions, and can be incorporated into HIV prevention interventions and used as a mediator variable. In addition, it can be used as an outcome measure where a follow-up is not feasible. The SIIS can also be tailored for additional HIV-related behaviors such as HIV-testing, adhering to antiretroviral medication, prescribing and adhering to pre-exposure prophylaxis, and other health behaviors.

Abstract
BACKGROUND Despite rapid increases in crystal methamphetamine (CM) use worldwide and established gendered patterns of use, empirical research on CM injection initiation among sex workers is limited. Given the wide range of harms associated with CM, alongside stimulant effects including sexual dis-inhibition and prolonged awake-ness, this study aimed to longitudinally investigate socio-structural predictors of initiating CM injection among sex workers in Vancouver, Canada. METHODS Data (2010-2014) were drawn from a community-based cohort of women sex workers: AESHA (An Evaluation of Sex Workers Health Access). Participants completed bi-annual interviewer-administered questionnaires and HIV/STI testing. Kaplan Meier methods and Cox proportional hazards regression were used to model predictors of CM injection initiation among CM injection-naïve participants. RESULTS Of 455 participants eligible at baseline, 14.3% (n=65) injected CM for the first time over follow-up, with an incidence density of 6.79 per 100 person-years (95% Confidence Interval [CI] 5.30-8.69). In multivariable analysis, injection heroin use (Adjusted Hazard Ratio [AHR] 6.11; 95%CI 3.24-11.52), having an intimate partner who injects drugs (AHR 2.93; 95%CI 1.57-5.46), workplace violence (AHR 2.85; 95%CI 1.74-4.67), HIV seropositivity (AHR 2.69; 95%CI 1.45-5.00), and childhood abuse (AHR 1.86; 95%CI 0.99-3.49) were independently associated with initiating CM injection. CONCLUSIONS Findings underscore the gendered and social risk environment of CM injection initiation among sex workers. The strong influences of historical/workplace violence, coupled with heroin injection (known to be self-medicating for post-traumatic stress) as a primary risk pathway, emphasize the urgency of increasing access to integrated, trauma-informed addiction treatment and HIV care for marginalized women.

Abstract
OBJECTIVE To present an unusual case of spontaneous pneumomediastinum subsequent to recreational amphetamine use. CASE REPORT A young African American adult male was admitted to internal medicine service for treatment of rhabdomyolysis secondary to methamphetamine use. On admission, he was complaining of chest pain in addition to nausea and generalized muscle aches. By his second hospital day, chest pain had resolved yet physical exam demonstrated crepitation of the anterior chest and left axilla. Portable chest x-ray revealed subcutaneous emphysema in addition to pneumomediastinum. CONCLUSION Spontaneous pneumomediastinum is a rare complication of amphetamine use that is often associated with subcutaneous emphysema and can be diagnosed with chest x-ray. Management is conservative, with observation, pain control, and supplemental oxygen as needed.

Abstract
UNLABELLED Methamphetamine, a highly addictive psychostimulant drug, is widely used by substance users who are not motivated to undergo treatment throughout the world, including Iran. This research was conducted to evaluate the effectiveness of a brief home-based social work motivational intervention (HSWMI) to encourage male methamphetamine users to participate in a treatment program. METHOD Fifty-six unmotivated male methamphetamine users participated in a randomized controlled trial. The case group received the HSWMI in addition to the usual consulting services in the clinic; the control group just received the usual consulting services. Data were collected 7 and 90 days after the intervention to evaluate participation and retention in a treatment program. Data were analyzed using the chi-square test. RESULTS Drug users with a mean age of 32.55 years and mean duration of drug use of 7.73 years, participated in the case (n = 28) and control (n = 28) groups. The case group participated in treatment programs significantly more than the control group and the retention rate for the case group was significantly higher than for the control group. CONCLUSION This brief HSWMI was effective to increase the motivation of methamphetamine users to participate and remain in treatment programs. This intervention can be implemented by social workers in substance use treatment centers.

Abstract
Homeless youths' social networks are consistently linked with their substance use. Social networks influence behavior through several mechanisms, especially social norms. This study used sociometric analyses to understand whether social norms of drug use behaviors are clustered in network structures and whether these perceived norms (descriptive and injunctive) influence youths' drug use behaviors. An event-based approach was used to delineate boundaries of the two sociometric networks of homeless youth, one in Los Angeles, CA (n = 160) and the other in Santa Monica, CA (n = 130). Network characteristics included centrality (i.e., popularity) and cohesiveness (location in dense subnetworks). The primary outcome was recent methamphetamine use. Results revealed that both descriptive and injunctive norms influenced methamphetamine use. Network cohesion was found to be associated with perception of both descriptive and injunctive norms in both networks, however in opposite directions. Network interventions therefore might be effective if designed to capitalize on social influence that naturally occurs in cohesive parts of networks.

Abstract
We examined individual-level, partnership-level, and sexual event-level factors associated with condom use during receptive anal intercourse (RAI) among 163 low-income, racially/ethnically diverse, HIV-negative men who have sex with men (MSM) in Los Angeles (2007-2010). At baseline, 3-month, and 12-month visits, computer-assisted self-interviews collected information on ≤3 recent male partners and the last sexual event with those partners. Factors associated with condom use during RAI at the last sexual event were identified using logistic generalized linear mixed models. Condom use during RAI was negatively associated with reporting ≥ high school education (adjusted odds ratio [AOR] = 0.32, 95 % confidence interval [CI] 0.11-0.96) and methamphetamine use, specifically during RAI events with non-main partners (AOR = 0.20, 95 % CI 0.07-0.53) and those that included lubricant use (AOR = 0.20, 95 % CI 0.08-0.53). Condom use during RAI varies according to individual-level, partnership-level, and sexual event-level factors that should be considered in the development of risk reduction strategies for this population.

Abstract
BACKGROUND Despite chemical similarities, ADHD stimulants and methamphetamine have distinct use patterns in the community. This study compared the characteristics of nonmedical ADHD stimulants users and methamphetamine users in a household sample. METHODS In data from the 2009-2011 National Survey on Drug Use and Health, adult and adolescent stimulant users were categorized into three mutually exclusive subgroups: nonmedical ADHD stimulant users only (STM users), methamphetamine users (METH users), and both nonmedical ADHD stimulant and methamphetamine users (STM/METH users). Multivariate logistic regression analyses identified the substance comorbidity, mental health, and deviant behavior characteristics associated with these three groups. RESULTS Compared to adolescent STM users, STM/METH users were more likely to be female, younger and uninsured while METH users were more likely to be younger, in a minority group and from a higher-income family. Compared to adult STM users, METH and STM/METH users were more likely to be male, older, uninsured, no longer married, and to be from rural areas. Adolescent METH users were more likely than STM users to report illegal drug use while adult METH users were less likely to report prescription drug use than their STM user counterparts. Overall, adult and adolescent STM/METH users were more likely to report substance use, mental health problems and deviant behaviors compared to STM users. CONCLUSION The characteristics of STM users differ from METH and STM/METH users, and their associations with substance use and psychiatric comorbidities differ by age. Findings have implications for understanding the risks for stimulant use in different age subgroups.

Abstract
BACKGROUND Methamphetamine has become one of the most widely used illicit substances in the world. We measured the prevalence and identified the correlates of methamphetamine use amongst current injection drug users (IDUs) in a China-Myanmar border region. METHODS A cross-sectional survey including interviews and serological testing was conducted in 2012. Chinese IDUs who had injected within the past six months and aged ≥ 18 years were recruited using respondent-driven sampling (RDS). Logistic regression indentified factors associated with current methamphetamine use. RESULTS Among 370 IDUs recruited, prevalence of lifetime and current methamphetamine use was 84.2% and 75.2% respectively. Amongst 293 current users, 18.1% ever purchased methamphetamine from Myanmar while 8.9% ever used it there during the past 6 months. IDUs who had cross-border activities, including purchasing drugs (AOR: 1.20; 95% CI: 1.10, 1.31) and visiting family/friends, doing business or odd jobs in Myanmar (AOR: 1.13; 95% CI: 1.02, 1.24) were more likely to use methamphetamine in the past six months. Other factors independently associated with current methamphetamine use included being younger (aged ≤ 25 years, AOR: 1.24; 95% CI: 1.09, 1.41), being syphilis positive (AOR: 1.17; 95% CI: 1.03, 1.33), having used previously self-used needle/syringe (AOR: 1.20; 95% CI: 1.08, 1.34) and recently received prevention services (AOR: 1.15; 95% CI: 1.04, 1.28). CONCLUSION Methamphetamine has become another major drug of use and poses the serious concern among injecting drug users living in the China/Myanmar border region. The bi-national cooperation is urgently needed to develop targeted effective intervention strategies.
