Abstract
Recently we published in this journal an enantioselective high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the quantitative determination of 3,4-methylenedioxymethamphetamine (MDMA) and its major phase-1 metabolites, 4-hydroxy-3-methoxyamphetamine (HMA), 4-hydroxy-3-methoxymethamphetamine (HMMA) and 3,4-methylenedioxyamphetamine (MDA) in human plasma, sweat, oral fluid and urine. Since we did not achieve simultaneous enantioseparation of all 4 compounds with a single chiral column, two amylose-based chiral columns were used alternatively. Further optimization of the mobile phase in the present study enabled baseline separation of all four pairs of enantiomers on a single Lux AMP column. In addition, by optimization of the column dimension and applied flow-rate it became possible to complete the separation within 6 minutes. These new methods were applied to the analysis of human plasma, oral fluid and urine. While results on the concentration of MDMA and its metabolites in various biological fluids were reported in our recent publication, in the present study an attempt was made to hydrolyze glucuronides in urine samples by using alternatively, hydrochloric acid or glucuronidase and to evaluate the effect of hydrolysis on the concentration and enantiomeric distribution of hydroxy metabolites of MDMA such as HMA and HMMA.

Abstract
OBJECTIVE Anxiety and depression are prevalent mental health problems in people who use illicit stimulants. Improved understanding of the temporal relationship between methamphetamine, ecstasy/MDMA, or cocaine use with anxiety or depression informs public health interventions and treatment options for those experiencing this co-occurrence. This narrative systematic review sought to examine associations and temporality between the use of methamphetamine, ecstasy/MDMA, or cocaine, with anxiety or depressive symptoms. Method Systematic searches of 4 electronic databases were conducted up to August 2023. Study eligibility included the measurement of anxiety and/or depressive symptoms, and frequency of illicit stimulant use (methamphetamine, cocaine, or ecstasy/MDMA) at two separate time points, with data analysis of the association between these variables. The Joanna Briggs Critical Appraisal Checklist was utilised to assess quality. Data was extracted, and a narrative synthesis incorporating an eight-criteria framework to assess associations was conducted. Results 4432 studies were screened for eligibility; 11 studies (3 RCTs and 8 prospective cohort studies) were included. Evidence for an association between depressive symptoms and methamphetamine use was demonstrated in six studies, with temporal evidence in three studies supporting methamphetamine use preceding depressive symptoms. Three studies reported an association between cocaine use and depressive symptoms. Evidence for associations with any of the illicit stimulants and anxiety symptoms was lacking. CONCLUSIONS There was some evidence to support a case for temporality, particularly for methamphetamine use and depressive symptoms. Investing in longitudinal studies is pivotal to understanding the dynamic and reciprocal relationship between illicit stimulant use and anxiety or depressive symptoms. A limitation of the study was the variation in the measurement and analysis of outcomes.

Abstract
Chemsex refers to the use of psychoactive substances with sex. We carried out a systematic scoping review of methodological characteristics of chemsex research among men who have sex with men (MSM), published between 2010 and 2020. For inclusion, chemsex had to be the main focus, and studies had to specify GHB/GBL, stimulant (amphetamine, crystal meth, ecstasy/MDMA, cathinones, cocaine) and/or ketamine use with sex as a variable. From 7055 titles/abstracts, 108 studies were included, mostly cross-sectional, and from Western countries. About one-third of studies recruited exclusively from clinical settings. A majority of these recruited from sexually transmitted infection (STI) clinics. The included quantitative studies analyzed possible associations between chemsex and STI health (40%), mental health (15%), drug health (12%), sexological health (10%), and post-diagnostic HIV health (7%). Most studies included GHB/GBL and crystal meth in their operationalization of chemsex. Definitions and operationalizations of chemsex vary greatly in the literature, and researchers of chemsex among MSM should consider ways in which this variation impacts the validity of their results. More studies are needed among MSM in non-high income and non-Western countries, and examination of possible links between chemsex and post-diagnostic HIV health, sexological health, and mental health.

Abstract
The conventional methamphetamine (MA) detection method using the Simon reaction can be affected by false positives owing to compounds similar to aliphatic secondary amines. In this study, we examined the new Simon reaction to improve the qualitative accuracy of MA detection to discriminate substances that give false positives in a conventional Simon reaction. After the conventional Simon reaction for MA and false positives (N-isopropylbenzylamine (NIP-BA), N-methylbenzylamine (NMe-BA), L-proline (Pro), and L-hydroxyproline (HYP)), which are colored blue, di-tert-butyl dicarbonate (t-Boc) reagent was added, and color tone changes were observed. When t-Boc was added to the false positives (NIP-BA, NMe-BA, Pro, and HYP), the colors of MA, Pro, and HYP changed to purple; NIP-BA changed to blue; and NMe-BA changed to light pink after 3 min. These results suggested that MA can be differentiated from NIP-BA and NMe-BA. Furthermore, the solid-phase chromogenic method was examined, and it was confirmed that MA could be differentiated from Pro and HYP. The method developed in this study should increase the accuracy of MA appraisal at crime scenes and contribute to the reduction of misclassifications arising from false-positive substances.

Abstract
BACKGROUND AND AIMS Total abstinence has historically been the goal of treatment for substance use disorders; however, there is a growing recognition of the health benefits associated with reduced use as a harm reduction measure in stimulant use disorders treatment. We aimed to assess the validity of reduced stimulant use as an outcome measure in randomized controlled trials (RCTs) of pharmacological interventions for stimulant use disorder. DESIGN We conducted a secondary analysis of a pooled dataset of 13 RCTs. SETTING AND PARTICIPANTS Participants were individuals seeking treatment for cocaine or methamphetamine use disorders (N = 2062) in a wide range of treatment facilities in the United States. MEASUREMENTS We validated reduced stimulant use against a set of clinical indicators drawn from harmonized measurements, including severity of problems caused by drug use, comorbid depression, global severity of substance use and improvement, severity of drug-seeking behavior, craving and high-risk behaviors, all assessed at the end of the trial, as well as follow-up urine toxicology. A series of mixed effect regression models was conducted to validate reduction in frequency of use against no reduction in use and abstinence. FINDINGS More participants reduced frequency of primary drug use than achieved abstinence (18.0% vs. 14.2%, respectively). Reduced use was significantly associated with decreases in craving for the primary drug [60.1%, 95% confidence interval (CI) = 54.3%-64.7%], drug seeking behaviors (41.0%, 95% CI = 36.6%-45.7%), depression severity (39.9%, 95% CI = 30.9%-48.3%), as well as multiple measures of global improvement in psychosocial functioning and severity of drug-related problems, albeit less strongly so than abstinence. Moreover, reduced use was associated with sustained clinical benefit at follow-up, as confirmed by negative urine tests (adjusted odds ratio compared with those with no reduction in use: 0.50, 95% CI = 0.35-0.71). CONCLUSION Reduced frequency of stimulant use appears to be associated with meaningful improvement in various clinical indicators of recovery. Assessment of reduced use, in addition to abstinence, could broaden the scope of outcomes measured in randomized controlled trials of stimulant use disorders and facilitate the development of more diverse treatment approaches.

Abstract
BACKGROUND AND OBJECTIVES Although both drugs and negative emotions can trigger drug craving or relapse in individuals with methamphetamine-use disorder (MUD), it remains unclear whether individuals with MUD have attentional biases toward both drug and negative emotional cues and whether this bias involves attention orientation or difficulty in attention disengagement. This study aimed to measure different components of attentional bias toward drug-related and negative emotional cues in individuals with MUD. METHODS Two dot-probe tasks were used to investigate attentional bias toward drug (drug task) and negative emotional cues (emotion task) in individuals with MUD. Forty-three males with MUD (average age of 43.44 ± 11.91 years, average drug-use duration of 11.35 ± 8.39 years) participated in the study voluntarily. RESULTS There was a significant interaction between the task type and location (p = .01). Specifically, for drug cues, participants showed significant difficulty in attention disengagement toward drug cues (p = .01); however, no attention orientation (p = .46). For negative emotional cues, neither significant attention orientation (p = .07) nor significant difficulty in attention disengagement (p = .50) was found. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE Attentional bias in individuals with MUD was highly selective for drug cues; thus, difficulty in attention disengagement from drug cues can be considered a potential mediating mechanism for attentional bias modification interventions for individuals with MUD. This study served to generate hypotheses or suggest future experiments on interventions for individuals with MUD.

Abstract
Safe and effective therapeutics for psychostimulant use disorders remain elusive. Deep brain stimulation (DBS), which is FDA-approved for other indications, is a promising candidate for treating severe substance use disorders. We examine the clinical and preclinical evidence for DBS of the nucleus accumbens as a possible therapeutic option for cocaine and methamphetamine use disorders. Limitations of the literature to date, including the lack of females included in studies evaluating the efficacy of DBS, and new strategies to optimize brain stimulation approaches are also discussed.

Abstract
BACKGROUND AND OBJECTIVES The gender gap in prevalence of substance-use disorders has narrowed. However, gender differences in stimulant misuse have not been well-characterized in recent years. The aim of this study was to quantify gender differences in past-year stimulant misuse and stimulant-use disorder, separated by stimulant type (cocaine/crack, prescription stimulants, and methamphetamine). In an exploratory aim, we investigated whether gender differences were moderated by age or sexual orientation. METHODS We combined data from the National Survey on Drug Use and Health from 2015 to 2019 (unweighted N = 282,768) to test gender differences in the prevalence of past-year stimulant misuse. RESULTS Results indicated that stimulant misuse was significantly more prevalent in men than women for all stimulant types for both past-year use and past-year use disorder. The magnitude of this sex difference was smallest for prescription stimulants, where men had 1.37 times higher odds of past-year misuse and no gender difference was observed in the prevalence of prescription stimulant-use disorder. The magnitude of gender differences also varied based on both age and sexual orientation. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE Illicit stimulant misuse continues to be more common in men than in women; however, gender differences are more modest for prescription stimulant misuse, suggesting a narrowing of this historical gender difference.

Abstract
BACKGROUND Recovery from addiction is frequently equated with abstinence. However, some individuals who resolve an addiction continue to use substances, including via substitution (i.e., increased use of one substance after eliminating/ reducing another). Substitution may play a distinct role during early recovery (≤ 1 year), as this period is marked by dramatic change and adjustment. Cannabis is one of the most used substances and is legal for medical and recreational use in an increasing number of states. Consequently, cannabis an increasingly accessible substitute for substances, like fentanyl, heroin, cocaine and methamphetamine, with higher risk profiles (e.g., associated with risk for withdrawal, overdose, and incarceration). METHODS Fourteen participants reported that they had resolved a primary opioid or stimulant addiction and subsequently increased their cannabis use within the previous 12 months. Using grounded theory, the interviewer explored their experiences of cannabis use during early recovery. Data were analyzed in three stages: line by line coding for all text related to cannabis use and recovery, focused coding, and axial coding to generate a theory about recovery with cannabis substitution. The motivational model of substance use provided sensitizing concepts. RESULTS & DISCUSSION The final sample included eight men and six women ranging in age from 20 to 50 years old. Three participants resolved an addiction to methamphetamine and the remaining 11, an addiction to opioids. Participants explained that cannabis was appealing because of its less harmful profile (e.g., no overdose risk, safe supply, few side effects). Participants' primary motives for cannabis use included mitigation of psychiatric symptoms, withdrawal/ cravings, and boredom. While cannabis was effective toward these ends, participants also reported some negative side effects (e.g., decreased productivity, social anxiety). All participants described typical benefits of recovery (e.g., improved self-concept, better relationships) while continuing to use cannabis. Their experiences with and beliefs about substitution suggest it can be an effective strategy for some individuals during early recovery. CONCLUSIONS Cannabis use may benefit some adults who are reducing their opioid or stimulant use, especially during early recovery. The addiction field's focus on abstinence has limited our knowledge about non-abstinent recovery. Longitudinal studies are needed to understand the nature of substitution and its impact on recovery over time.

Abstract
BACKGROUND AND AIM Non-medical use of Pregabalin (PGB) is a growing concern in many countries because of the serious consequences associated with their abuse. Judicial cases within the probation system, multiple drug users, and patients in treatment programs administered PGB at higher doses than suggested, commonly without prescription. For this reason, it is important to analyze PGB by adding it to the routine analysis scale in determining whether PGB is used for medical purposes or abuse. In this study, PGB analyzed (single or multiple substance use, concomitant substances) in urine samples of forensic and clinical cases by liquid chromatography-tandem mass spectrometry (LC-MS/MS). In addition to the sociodemographic and clinical characteristics of pregabalin-positive cases, the results were evaluated separately from a clinical and forensic perspective. METHODS All urine samples which was admitted to Addiction Toxicology Laboratory from 'drug abuse probation system' (forensic cases, n = 640) and from various departments of our hospital (clinical cases, n = 371) between December 2022 and April 2023. Screening analysis were carried out by immunoassay in total 1011 cases. LC-MS/MS method simultaneously analyzed amphetamine, benzoilecgonine, cocaine, codeine, metamphetamine, morphine, 3,4-metilenedioksi-N-metilamfetamin (MDMA), 11-nor-9-karboksi-Δ9-tetrahidrokannabinol and pregabalin in urine samples. PGB was added to the our routine substance screening analysis scale in December 2022 to detect pregabalin use. RESULTS PGB was detected in 12.3% of probabition cases and 13.2% of clinical cases. The mean age of PGB positive cases was 26.55 ± 7,52 years old, predominantly males (%85,9). Single PGB was detected in 53.2% of forensic cases (n = 42), and 38.7% of clinical cases (n = 19). The most common substance detected concomitantly with PGB was amphetamine type stimulants (ATSs:amphetamine, methamphetamine, ecstasy/MDMA etc.) (22.8% of forensic cases and 46.9% of clinical cases), followed by concomitant cannabis use (24.1% of forensic cases and 26.5% of clinical cases). Concomitant opioid use was rare (1.3% of forensic cases and 4.1% of clinical cases). Detection of PGB was significantly different across months on which the samples were collected (x2 = 82.8, df=4, p < 0.001). CONCLUSION Inconsistently with previous studies suggesting opioids as the most prevalant substances concominant with PGB, our results showed that stimulants (especially ATSs) were the most prevelant substances concominant with PGB, followed by cannabis. High proportion of PGB detection in probabition cases, frequently as a single substance abuse takes attention. These results suggest that PGB, may be used to avoid legal consequences. It is important for laboratories to be aware that they need to make changes as addition of newly abused substances in their analysis panels, when necessary, as differences between regions and cultures affect substance use patterns.

Abstract
Drug addiction represents a multifaceted and recurrent brain disorder that possesses the capability to create persistent and ineradicable pathological memory. Deep brain stimulation (DBS) has shown a therapeutic potential for neuropsychological disorders, while the precise stimulation targets and therapeutic parameters for addiction remain deficient. Among the crucial brain regions implicated in drug addiction, the dorsal raphe nucleus (DRN) has been found to exert an essential role in the manifestation of addiction memory. Thus, we investigated the effects of DRN DBS in the treatment of addiction and whether it might produce side effects by a series of behavioral assessments, including methamphetamine priming-induced reinstatement of drug seeking behaviors, food-induced conditioned place preference (CPP), open field test and elevated plus-maze test, and examined brain activity and connectivity after DBS of DRN. We found that high-frequency DBS of the DRN significantly lowered the CPP scores and the number of active-nosepokes in the methamphetamine-primed CPP test and the self-administration model. Moreover, both high-frequency and sham DBS group rats were able to establish significant food-induced place preference, and no significant difference was observed in the open field test and in the elevated plus-maze test between the two groups. Immunofluorescence staining and functional magnetic resonance imaging revealed that high-frequency DBS of the DRN could alter the activity and functional connectivity of brain regions related to addiction. These results indicate that high-frequency DBS of the DRN effectively inhibits methamphetamine priming-induced relapse and seeking behaviors in rats and provides a new target for the treatment of drug addiction.

Abstract
Salinity is an environmental stress that severely impacts rice grain yield and quality. However, limited information is available on the molecular mechanism by which salinity reduces grain quality. In this study, we investigated the milling, appearance, eating and cooking, and nutritional quality among three japonica rice cultivars grown either under moderate salinity with an electrical conductivity of 4 dS/m or under non-saline conditions in a paddy field in Dongying, Shandong, China. Moderate salinity affected rice appearance quality predominantly by increasing chalkiness rate and chalkiness degree and affected rice eating and cooking and nutritional quality predominantly by decreasing amylose content and increasing protein content. We compared the expression levels of genes determining grain chalkiness, amylose content, and protein content in developing seeds (0, 5, 10, 15, and 20 days after flowering) of plants grown under saline or non-saline conditions. The chalkiness-related gene Chalk5 was up-regulated and WHITE-CORE RATE 1 was repressed. The genes Nuclear factor Y and Wx, which determine amylose content, were downregulated, while protein-content-associated genes OsAAP6 and OsGluA2 were upregulated by salinity in the developing seeds. These findings suggest some target genes that may be utilized to improve the grain quality under salinity stress conditions via gene-pyramiding breeding approaches.

Abstract
Internationally, HIV-related stigma and crystal methamphetamine (meth) use have been described as barriers to treatment adherence among gay, bisexual, and other men who have sex with men (gbMSM). Crystal meth use has been increasing among gbMSM in the Metropolitan Area of Mexico City (MAMC). Therefore, this study aimed to determine the association between HIV-related stigma and HIV treatment adherence among gbMSM who use crystal meth in the MAMC. This study was undertaken as part of an exploratory study of crystal meth use in the MAMC. The data were collected from September to December 2021 through an encrypted online survey. Participants (n = 89) were gbMSM adults living with HIV who reported crystal meth use in the past month that were recruited through an online snowball sampling. The online survey included questions about HIV treatment adherence, sexual behaviors, the Alcohol, Smoking, and Substance Involved Screening Test, and the HIV-Related Stigma Mechanisms Scale. Logistic regression analyses assessed the association between HIV-related stigma and HIV treatment adherence. The multivariate logistic regression model showed that, controlling for health insurance [adjusted odds ratio (AOR) = 0.13; 95% confidence intervals (CI) = 0.02-0.59] and educational level (AOR = 0.16; 95% CI = 0.02-0.88), non-adherence to HIV treatment was independently associated with higher HIV-related stigma (AOR = 1.06; 95% CI = 1.01-1.12). Public health policies must include HIV-related stigma and substance use in treating gbMSM with HIV.

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
Addiction to psychostimulant drugs, such as cocaine, D-amphetamine, and methamphetamine, is a public health issue that substantially contributes to the global burden of disease. Psychostimulant drugs promote an increase in dopamine levels within the mesocorticolimbic system, which is central to the rewarding properties of such drugs. Cannabinoid receptors (CB1R and CB2R) are expressed in the main areas of this system and implicated in the neuronal mechanisms underlying the rewarding effect of psychostimulant drugs. Here, we reviewed studies focusing on pharmacological intervention targeting cannabinoid CB1R and CB2R and their interaction in the modulation of psychostimulant responses.

Abstract
BACKGROUND The opioid overdose crisis is one of the worst public health crises ever to face the US and emerging evidence suggests its effects are compounded by the presence of drug adulterants. Here we report our efforts to characterize the adulterants present within the local fentanyl supply of San Diego County, obtained from undifferentiated drug samples seized by local law enforcement over the calendar year 2021. METHODS Thirty-two participating local law enforcement agencies across San Diego submitted 4838 unknown individual illicit drug samples (total of 312 kg) to the San Diego County Sheriff's Department Regional Crime Laboratory for identification. RESULTS Qualitative analysis of these samples via FTIR and GC-MS identified methamphetamine (38.7%), fentanyl (20.8%), diacetylmorphine (heroin) (10.2%), codeine (5.8%) and alprazolam (4.3%) as the most common illicit substances and the presence of 52 unique adulterants. The most common adulterants included 4-methylaminoantipyrine (4-MAAP) (10.9%), mannitol (9%), acetaminophen (8.5%), methamphetamine (4.2%), diacetylmorphine (heroin) (3.6%), tramadol (1.9%), and xylazine (1.7%). Several additional pharmacologically active adulterants and contaminants of interest were also identified. CONCLUSION This analysis is vital for public health use and harm reduction efforts at the level of the individual consumer. Continued direct surveillance of the drug supply is necessary for the detection of potentially harmful adulterants that may pose serious threats to the public.

Abstract
Dried blood spot (DBS) technology is a simple and convenient method for collecting, transporting, and storing blood samples on filter paper, and has numerous applications in the clinical, research, and public health settings. This technique is gaining popularity in the field of forensic science because it facilitates the rapid analysis of prohibited drugs in blood samples and offers significant advantages in toxicology scenarios such as drinking-driving screening, drug abuse detection, and doping detection. However, the lack of a standardized system and the fact that its stability and reliability have not been thoroughly researched and demonstrated limit its application in judicial practice in China. DBS samples can be prepared, stored, and analyzed in various ways, all of which may significantly affect the results. In this study, we developed a method based on ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) that focuses on the preparation, pretreatment, analysis, and storage of DBS samples. A thorough investigation was conducted to examine the optimal preparation conditions, including the blood spot matrix, drying technique, and preprocessing parameters, such as the solvent and extraction method. Moreover, the analytical conditions, such as the mobile phase system and elution gradient, were established to facilitate the quantitative detection of methamphetamine, lidocaine, ketamine, fentanyl, and diazepam in both DBS and whole-blood samples. The impact of storage conditions, such as the temperature, humidity, and sealing, on the analytical results of the DBS and whole-blood samples was also examined. The results showed a strong linear relationship for lidocaine and fentanyl within the range of 0.5-100 ng/mL. Similarly, methamphetamine, ketamine, and diazepam exhibited good linearity within the range of 2-100 ng/mL. The coefficients of determination (r2) ranged from 0.9983 to 0.9997, and the limits of detection ranged from 0.2 to 0.5 ng/mL, indicating a high degree of correlation and sensitivity. Stability tests demonstrated that the five target substances remained stable in the DBS for 60 days, with the measured contents deviating from the nominal values by 15%. Moreover, the measurement results of the DBS samples were highly similar to those of the whole-blood samples, with mean percentage differences of 4.44%, 3.50%, 7.66%, 5.10%, and 5.25% for fentanyl, diazepam, ketamine, lidocaine, and methamphetamine, respectively. Throughout the 60-day storage period, the maintenance of temperatures of -20 and 4 ℃, as well as sealing and dry storage, was not necessary. Room temperature was the most practical storage environment for the DBS samples. The results for each target showed very small concentration differences between the whole-blood and DBS samples, indicating that the DBS samples were suitable for drug and poison analysis in blood. Furthermore, the DBSs exhibited high quantitative consistency with the whole-blood samples, rendering them suitable matrices for preserving blood samples. Because DBS samples are easy to handle and store, they can realize the lightweight preservation of blood samples and provide a novel solution for the analysis and preservation of blood samples in public security practice. We recommend conducting comprehensive validations before utilizing DBS for analysis, particularly in terms of quantification, to ensure the judicial reliability of the results.

Abstract
BACKGROUND Drug addiction is a serious problem worldwide and is influenced by genetic factors. The present study aimed to investigate the association between genetics and drug addiction among Han Chinese. METHODS A total of 1000 Chinese users of illicit drugs and 9693 healthy controls were enrolled and underwent single nucleotide polymorphism (SNP)-based and haplotype-based association analyses via whole-genome genotyping. RESULTS Both single-SNP and haplotype tests revealed associations between illicit drug use and several immune-related genes in the major histocompatibility complex (MHC) region (SNP association: log10BF = 15.135, p = 1.054e-18; haplotype association: log10BF = 20.925, p = 2.065e-24). These genes may affect the risk of drug addiction via modulation of the neuroimmune system. The single-SNP test exclusively reported genome-wide significant associations between rs3782886 (SNP association: log10BF = 8.726, p = 4.842e-11) in BRAP and rs671 (SNP association: log10BF = 7.406, p = 9.333e-10) in ALDH2 and drug addiction. The haplotype test exclusively reported a genome-wide significant association (haplotype association: log10BF = 7.607, p = 3.342e-11) between a region with allelic heterogeneity on chromosome 22 and drug addiction, which may be involved in the pathway of vitamin B12 transport and metabolism, indicating a causal link between lower vitamin B12 levels and methamphetamine addiction. CONCLUSIONS These findings provide new insights into risk-modeling and the prevention and treatment of methamphetamine and heroin dependence, which may further contribute to potential novel therapeutic approaches.

Abstract
BACKGROUND Co-use of methamphetamine (MA) and opioids (pharmaceutical pills, heroin and fentanyls) has increased in the United States and is represented in rising mortality. Although coinciding with the import of low cost, high potency and purity methamphetamine, the relationship between supply and demand in propelling this polydrug use is not well understood. We consider the influence of macro changes in supply on the uptake of opioid and methamphetamine co-use by injection at the level of individual drug and injection initiation in West Virginia, a state which leads the US in drug overdose mortality. METHOD We recruited n = 30 people for semi-structured interviews who self-reported injecting heroin/fentanyl and using methamphetamine by any route at a West Virginia syringe service program and through snowball sampling. Interviews were recorded and transcripts analyzed using a thematic approach. Ethnographic observation was also conducted and recorded in fieldnotes. Sequence of substance and mode of use initiation and use trajectories for opioids and stimulants were charted for each participant. RESULTS A clear pattern of individual drug initiation emerged that matched each successive supply wave of the US overdose epidemic: 25 participants had initiated opioid use with pills, followed by heroin, often mixed with/replaced by fentanyl, and subsequently added methamphetamine use. For participants, the supply and consumption of opioid analgesics had set in motion a series of steps leading to the addition of stimulant injection to existing opioid injecting repertoires. Unlike other studies that have found a birth cohort effect in patterns of initiation, participants showed the same sequence across age groups. Considerations of economy, availability, dependence, tolerance and the erosion of taboos that marked transitions from opioid pills to heroin injection influenced these subsequent trajectories in novel ways. The form, timing and extent of opioid and stimulant consumption was influenced by four stages of the changing drug supply, which in turn reflected back on demand. CONCLUSION Transformations in the social meaning and supply of methamphetamine enabled these transitions while other desired, non-injectable drugs were difficult to obtain. We discuss policy implications of injectable drugs' market dominance at this location and possible interventions.

Abstract
OBJECTIVE This study aims to review applications of immersive, head-mounted display (HMD)-delivered virtual reality (VR) technology for the assessment and modification of clinically relevant factors (e.g., craving, electrophysiological reactions, brain activation) present in illicit substance use. METHOD A PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses)-guided systematic review was conducted and retrieved articles from four databases. Articles included were peer-reviewed, empirical studies and were screened on criteria pertaining to sample using (or with a history of using) substances and measurement of substance-related factors. RESULTS Eighteen articles met inclusion criteria. Applications of immersive, HMD-delivered VR in assessment and modification were most prevalent among individuals using (or with a history of using) methamphetamine and targeted subjective craving, electrophysiological biomarkers (e.g., heart rate variability, skin conductance), and brain activity. Environments presented through VR involved substance-relevant cues (e.g., paraphernalia) and neuropsychological assessments. The majority of assessment studies elicited clinically relevant factor(s) present in illicit substance use through VR and all reviewed modification studies effectively reduced clinically relevant factors in methamphetamine and opioid use (e.g., craving, subjective pain). CONCLUSIONS There is evidence to support the use of immersive, HMD-delivered VR in the assessment and modification of clinically relevant factors in methamphetamine use, as well as preliminary evidence to support its effectiveness for clinically relevant factors in opioid use. Future research should further examine the effectiveness of HMD-delivered VR in modifying illicit substance use and triangulate biomarkers measured in individuals using illicit substances.

Abstract
OBJECTIVES Psychostimulant-related mortality is rising alongside increasing substance use-related hospitalizations, which are commonly complicated by patient-directed (or "against medical advice") discharges. Contingency management (CM) is an underused evidence-based treatment for substance use disorders with proven efficacy to support medication adherence. Our objective was to describe feasibility and preliminary effectiveness of a novel CM intervention incentivizing both drug use reduction and antibiotic adherence in the hospital setting. METHODS We conducted a pilot intervention of twice weekly CM for stimulant and/or opioid use disorder and antibiotic adherence conducted on inpatient wards and/or an embedded skilled nursing facility in an urban public hospital. Based on point-of-care urine drug test results and objective antibiotic adherence review, participants earned increasing opportunities to receive incentives. We measured feasibility via number of visits attempted and cost of gift cards dispensed. We evaluated effectiveness via antibiotic completion, discharge type, and participant perception of intervention effectiveness collected via structured survey. RESULTS Of 13 participants enrolled, most had opioid use disorder (fentanyl in 10/13) and stimulant use disorder (methamphetamine in 7/13). Almost all were receiving treatment for osteomyelitis and/or endocarditis (12/13). Feasibility challenges included competing demands of acute care with variable range of completed visits per participant (1-12 visits). Despite this, antibiotic completion was high (92%, 12/13 participants) with only two patient-directed discharges. Participants described CM as very effective in aiding infection treatment but had greater variability in beliefs regarding CM facilitation of reduced drug use. CONCLUSIONS Providing CM in the hospital setting may represent an effective approach to improving health outcomes by increasing antibiotic adherence and addressing substance use.

Abstract
Current guidelines recommend universal screening for substance use disorders in obstetric patients, and neonatal drug testing is also frequently performed. Meconium is often the preferred specimen type to detect neonatal drug exposure due to a longer window of detection compared to urine, but most laboratories send out meconium testing to specialized reference laboratories, which can delay results for several days or more. Here, we evaluate a rapid and definitive liquid chromatography-tandem mass spectrometry method for neonatal urine drug testing and compare results obtained using this method to paired meconium drug testing in 1,424 neonates for amphetamines, cocaine, cannabinoids, opiates, oxycodone and phencyclidine. Urine testing showed equivalent sensitivity to current meconium methods for detecting in utero exposure to amphetamines and cocaine.

Abstract
Amphetamine-type stimulants are the third most widely consumed category of illicit drugs worldwide. Faced with the growing problem of amphetamine-type stimulants, numerous qualitative and quantitative techniques have been developed to detect amphetamine (AMP), methamphetamine (MET), MDMA, MDEA or MDA in biological matrices, including hair. Hair analysis is widely used in forensic medicine, but one of its main drawbacks remains external contamination. In this study, we investigated the possibility of hair contamination through external exposure to blood containing AMP, MET MDMA, MDEA or MDA at 2 ng/mL; 20 ng/mL; 200 ng/mL or 2000 ng/mL after 6 h, 1, 3, 7 or 14 days of contact protected from light at room temperature (RT or 20 °C) or at 4 °C. Dried extracts of hair samples were analyzed by UPLC-MS/MS after extensive washings in several baths of water, methanol and acetone before grounding. At the end of our study, contamination of hair was observed from 6 h of contact with all tested amphetamine-type stimulants. The concentrations found in hair ranged from 3 ± 1 to 1464 ± 10 pg/mg, 5 ± 1 to 5070 ± 160 pg/mg, 3 ± 1 to 1269 ± 60 pg/mg, 4 ± 1 to 1860 ± 113 pg/mg and from 8 ± 1 to 1041 ± 44 pg/mg for AMP, MET, MDMA, MDEA and MDA, respectively. Possibly due to its low polar surface area, MET was the most prone to contaminate. As anticipated, hair contamination was mainly dependent on the concentration of all molecules in the contaminating blood, reaching the SOHT cut-off of 200 pg/mg when amphetamine-type stimulants are at toxic or lethal concentrations in the blood. These observations call for caution in interpreting exposure to these substances in such forensic situations.

Abstract
BACKGROUND As overdose deaths continue to rise, public health officials need comprehensive surveillance data to design effective prevention, harm reduction, and treatment strategies. Disparities across race and ethnicity groups, as well as trends in substance use, treatment, or overdose deaths, have been examined individually, but reports rarely compare findings across multiple substances or data sources. OBJECTIVE To provide a broad assessment of the overdose crisis, we describe trends in substance use, treatment, and overdose mortality across racial and ethnic groups for multiple substances. RESEARCH DESIGN We conducted a longitudinal, cross-sectional analysis comparing trends. SUBJECTS We identified self-reported use from the National Survey on Drug Use and Health, substance use treatment admissions from the Treatment Episode Data Set-Admissions, and overdose deaths from the CDC's Multiple Cause of Death files. MEASURES We measured rates of substance use, treatment, and deaths involving heroin, methamphetamine, and cocaine among United States adults from 2010 to 2019. RESULTS Heroin, methamphetamine, and cocaine use increased, though not all changes were statistically significant. Treatment admissions indicating heroin and methamphetamine increased while admissions indicating cocaine decreased. Overdose deaths increased among all groups: methamphetamine (257%-1,115%), heroin (211%-577%), and cocaine (88%-259%). Changes in rates of use, treatment, and death for specific substances varied by racial and ethnic group. CONCLUSIONS Substance use, treatment, and overdose mortality changed considerably, though not always equivalently. Identifying diverging trends in substance-related measures for specific substances and racial and ethnic groups can inform targeted investment in treatment to reduce disparities and respond to emerging changes in the overdose crisis.

Abstract
INTRODUCTION The administration of illicit drugs by injection is associated with considerable harm, including an increased risk of overdose. The chemical analysis of used syringes can enhance knowledge on injecting drug consumption beyond traditional data sources (self-report surveys). This additional information may be useful during significant global events like the COVID-19 pandemic. This study aimed to examine a snapshot of the drugs injected at the Medically Supervised Injecting Centre (MSIC) in Sydney, Australia, in 2019-2020. METHODS Used syringes were collected from MSIC across three periods throughout 2019 and 2020 (February 2019, March-April 2020 and June-September 2020). Drug residues were extracted from used syringes using methanol before detection by gas chromatography-mass spectrometry and ultra-performance liquid chromatography-tandem mass spectrometry. The chemical analysis results were compared to self-report data obtained from MSIC clients. RESULTS Heroin (46-53%), methamphetamine (24-34%) and pharmaceutical opioids (15-27%) were the most common drug residues detected. The chemically detected drugs had declining coherence with the drugs self-reported by MSIC clients across the time periods examined. DISCUSSION AND CONCLUSIONS There was no significant change in the drugs injected (heroin, methamphetamine and pharmaceutical opioids) across the three periods collected throughout varying COVID-19 lockdown restrictions. Changes in the frequency of other drugs injected and discrepancies between chemical analysis and self-report were potentially related to regulatory changes, degradation or misinformed sales. Routine chemical analysis of used syringes has provided an alternative information source to promote awareness of current drug trends and aid harm reduction.

Abstract
PURPOSE Incarceration rates are highest in rural communities, disproportionately exposing rural children to parental incarceration (PI). Substance use is a pressing public health issue-and a key driver of incarceration-in rural areas, yet limited research has examined PI as a social determinant of health for adolescent alcohol and drug use. This study links exposure to PI with rural adolescent substance use and examines the role of coresidence with parents in these associations. METHODS Data come from the 2019 Minnesota Student Survey, including 18,820 rural adolescents. Respondents self-reported experiences of PI (current, former, never), whether they lived with the parent at the time of incarceration, and past-year alcohol, marijuana, cocaine, heroin, and methamphetamine use. FINDINGS Over 22% of rural adolescents experienced PI. In adjusted logistic regression models, current PI was associated with greater past-year alcohol (aOR = 2.20), marijuana (aOR = 4.08), cocaine (aOR = 3.61), heroin (aOR = 4.96), and methamphetamine (aOR = 5.43) use compared to peers who never experienced PI. Current PI was also associated with greater counts of use. Associations between coresidence and substance use were largely nonsignificant. CONCLUSIONS The elevated risk for substance use in the context of rural PI and its adverse sequelae call for expanded prevention and intervention strategies that support adolescent health alongside targeted decarceration efforts in rural communities that reduce the number of families put in the potentially compromising situation of PI.

Abstract
INTRODUCTION Substance use, including drugs, alcohol and smoking have a significant health, social and economic impact. We aim to assess the rate and factors associated with treatment access among individuals with high-risk substance use. METHOD This study is a cross-sectional analysis of the 2019 Australian National Drug Strategy Household Survey (N = 22,015). Participants were persons with high-risk substance use based on the Alcohol, Smoking and Substance Involvement Screening Test-Lite (ASSIST-Lite) and current smokers. We measured self-reports of past 12-month engagement in a tobacco, alcohol or other drugs treatment program. RESULTS Overall, 0.4% had high-risk drug use (0.3% cannabis, 0.1% meth/amphetamine or 0.1% opioids), 7.4% had high-risk alcohol use, and 14.0% currently smoked. Among high-risk users, past 12-month treatment access rates were 50.6% [22.3-78.9%] for opioids, 27.1% [8.1-46.1%] for meth/amphetamine, 14.5% [4.3-24.7%] for cannabis, 9.6% [8.1-11.0%] for alcohol and 11.7% [10.6-12.9%] for current smoking. The primary source of treatment support was information and education (12.7% drugs, 4.6% alcohol, 4.0% smoking), followed by counselling (6.7% drugs, 4.5% alcohol, 3.0% smoking). Online or internet support was accessed by 5.9% (drug) and 1.6% (alcohol) people with high-risk use. Psychological distress was associated with treatment access (drugs: odds ratio 3.03 [0.77-11.95], p = 0.111; alcohol: odds ratio 3.16 [2.20-4.56], p ≤ 0.001; smoking: odds ratio 1.95 [1.52-2.49], p ≤ 0.001). DISCUSSION AND CONCLUSIONS The proportion of people engaging in risky substance use who had used treatment programs remains low, especially for alcohol. Public health strategies to scale up treatment access are warranted.

Abstract
An electroencephalographic (EEG) signature of auditory hallucinations (AHs) is important for facilitating the diagnosis and treatment of AHs in schizophrenia. We recorded EEG from 25 schizophrenia patients with recurrent AHs. During the period of AHs, EEG recordings exhibited significantly elevated beta2-band power in the temporal region, as compared to those recorded in the absence of AHs or during stimulation with verbal sounds. We further generated methamphetamine-treated rhesus monkeys exhibiting psychosis-like behaviors, including repetitive sudden searching actions in the absence of external intrusion, suggesting the occurrence of AHs. Epidural EEG beta2-band power in the temporal region of these monkeys was enhanced immediately after methamphetamine treatment and positively correlated with the frequency of sudden searching actions. Thus, the enhancement of temporal beta2-band oscillations represents a signature for AHs in both patients and a monkey model of psychosis, and this monkey model can be used for developing closed-loop neuromodulation approaches for the treatment of refractory AHs in schizophrenia.

Abstract
Repeated abuse of methamphetamine (METH) can cause dependence, repeated relapse of psychotic symptoms, compulsive drug-seeking behaviour, and various neurological symptoms. These long-term biological changes may be associated with epigenetic mechanisms; however, the association between METH use and epigenetic mechanisms has been poorly investigated. Thus, we performed an epigenome-wide association study of METH dependence using genomic DNA extracted from the blood samples of 24 patients with METH dependence and 24 normal controls. All participants were of Japanese descent. We tested the association between METH dependence and DNA methylation using linear regression analysis. We found epigenome-wide significant associations at four CpG sites, one of which occurred in the CNOT1 gene and another in the PUM1 gene. We especially noted the CNOT1 and PUM1 genes as well as several other genes that indicated some degree of association with METH dependence. Among the relatively enriched Gene Ontology terms, we were interested in terms of mRNA metabolism, respirasome, and excitatory extracellular ligand-gated ion channel activity. Among the relatively enriched Kyoto Encyclopedia of Genes and Genome pathways, we noted pathways of several neurological diseases. Our results indicate that genetic changes akin to those in other psychiatric or neurodegenerative disorders may also occur via epigenetic mechanisms in patients with METH dependence.

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.

Abstract
Contributions of brain glutamate (Glu) to conscious emotion are not well understood. Here, we evaluate the relationship of experimentally induced change in neocortical Glu (ΔGlu) and subjective states in well individuals, using combined application of pharmacological challenge, magnetic resonance spectroscopy (MRS), and comprehensive affective assessment. Drug challenge with d-amphetamine (AMP) (20 mg oral), methamphetamine (MA) (Desoxyn, 20 mg oral), and placebo (PBO) was conducted on three separate test days in a within-subjects double blind design. Proton MRS quantified neurometabolites in the right dorsal anterior cingulate cortex 140-150 min post-drug and PBO. Subjective states were assessed at half hour intervals over 5.5 h on each session, yielding 3792 responses per participant (91,008 responses overall, N = 24 participants), with self-reports reduced by principal components analysis (PCA). PCA produced a primary factor score of AMP- and MA-induced positive agency (ΔPA). MRS indicated drug-induced ΔGlu related positively to ΔPA (ΔGluMA r = +0.44, p < 0.05, N = 21), with large effects in females (ΔGluMA r = +0.52, p < 0.05; ΔGluAMP r = +0.61, p < 0.05, N = 11). Subjective states related to ΔGlu included rise in subjective stimulation, vigor, friendliness, elation, positive mood, positive affect (r's = +0.51 to +0.74, p < 0.05), and alleviation of anxiety in females (r = -0.61, p < 0.05, N = 11). These self-reports correlated with ΔGlu to the extent they loaded on ΔPA (r = 0.95 AMP, p = 5 × 10-10; r = 0.63 MA, p = 0.0015, N = 11), indicating the coherence of ΔGlu effects on emotional states. Timing data indicated Glu shaped positive emotion both concurrently and prospectively, with no relationship with pre-MRS emotion (ΔGluAMP r = +0.59 to +0.65, p's < 0.05; ΔGluMA r = +0.53, p < 0.05, N = 11). Together these findings indicate substantive, mechanistic contributions of neocortical Glu to positive agentic states in healthy individuals, which are most readily observed in women. The findings illustrate the promise of combined application of pharmacological challenge, comprehensive affective assessment, and MRS neuroimaging techniques in basic and clinical studies.

Abstract
INTRODUCTION Methamphetamine use is highly prevalent among men who have sex with men (MSM), but knowledge of the long-term dynamics, and how they are affected by substance use treatment, is limited. This study aimed to describe trajectories of methamphetamine use among MSM, and to evaluate the impact of treatment for any kind of substance use on frequency of methamphetamine use. METHODS This analysis used data from a cohort of MSM in Los Angeles, CA, who participated in semi-annual study visits from 2014 to 2022. The study characterized trajectories of methamphetamine use using a continuous time multistate Markov model with three states. States were defined using self-reported frequency of methamphetamine use in the past six months: frequent (daily), occasional (weekly or less), and never. The model estimated the association between receiving treatment for any kind of substance use and changes in state of frequency of methamphetamine use. RESULTS This analysis included 2348 study visits among 285 individuals who were followed-up for an average of 4.4 years. Among participants who were in the frequent use state, 65 % (n = 26) of those who were receiving any kind of substance use treatment at a study visit had reduced their methamphetamine use at their next visit, compared to 33 % (n = 95) of those who were not receiving treatment. Controlling for age, race/ethnicity, and HIV-status, those who reported receiving current treatment for substance use were more likely to transition from occasional to no use (HR: 1.63, 95 % CI: 1.10-2.42) and frequent to occasional use (HR: 4.25, 95 % CI: 2.11-8.59) in comparison to those who did not report receiving current treatment for substance use. CONCLUSIONS Findings from this dynamic modeling study provide a new method for assessing longitudinal methamphetamine use outcomes and add important evidence outside of clinical trials that substance use treatment may reduce methamphetamine use.

Abstract
OBJECTIVES There is little recent published data characterising acute psychosis associated with methamphetamine intoxication. We aim to describe the clinical features of psychosis, management of acute behavioural disturbance and disposition of patients with psychosis associated with acute methamphetamine intoxication. METHODS This is a retrospective review of patients presenting with acute (use within 24 h) methamphetamine intoxication, with features of psychosis (presence of delusions, hallucinations or formal thought disorder), to an ED over 4 months in 2020. All presentations were extracted from a toxicology unit database and each medical record reviewed. Demographics, past mental health diagnoses, clinical features and disposition were extracted. RESULTS There were 287 presentations of methamphetamine intoxication over the period. Of these 287 presentations, 205 (71%) had features of acute psychosis, occurring in 171 patients (111 males [65%], median age 36, range 16-57 years). Paranoid delusion occurred in 134 of 205 (65%) presentations and was the most common feature of psychosis. Chemical sedation was given to 194 (95%), with 143 (70%) receiving parenteral sedation to manage acute behavioural disturbance. Complete resolution of psychotic symptoms occurred in 170 of 205 (83%) of exposures. There were 9 of 205 (4%) presentations that resulted in a mental health admission. Most presentations - 200 of 205 (98%) - were managed within the ED, primarily the short-stay unit. The median length of stay was 15 h (interquartile range 11-20 h). CONCLUSIONS In this series of patients presenting to ED with acute methamphetamine intoxication, psychosis appeared to occur commonly and was mostly short-lived, resolving within 24 h in the majority of patients.

Abstract
The construction of a fluorescence aptamer sensor was achieved by employing the fundamental principle of fluorescence resonance energy transfer. By employing molecular modeling technologies to identify the binding site, the high-affinity aptamer APT-40nt was derived from the whole sequence and utilized on the graphene oxide (GO) fluorescent platform for the purpose of achieving a highly sensitive detection of methamphetamine (METH). The aptamer tagged with fluorescein (FAM) dye undergoes quenching in the presence of GO due to π-stacking interaction. With the addition of the target, the aptamer that has been tagged was detached from the GO surface, forming a stable complex with METH. This process resulted in fluorescence restoration of the system, and the degree of fluorescence restoration was proportional to METH concentration in the linear range of 1-50 and 50-200 nM. Notably, under optimized conditions, the detection limit of this aptasensor was as low as 0.78 nM, which meets the detection limit requirements of METH detection in saliva and urine in some countries and regions. Moreover, other common illicit drugs and metabolites had minimizing interference with the determination. The established aptasensor, therefore, has been successfully applied to detect METH in saliva and urine samples and exhibited satisfactory recoveries (87%-111%). This aptasensor has the advantages of low detection limit, excellent selectivity, ease of operation, and low cost, providing a promising strategy for on-site detection of METH in saliva and urine.

Abstract
Substance use disorder is an important mental health problem with increasing frequency. This study aims to investigate the 2D:4D ratio, Dr-I values (right-left differences), alexithymia, aggression, impulsivity, and attention deficit hyperactivity disorder (ADHD) symptoms in male patients with methamphetamine use disorder (MUD), opioid use disorder (OUD), and healthy controls. The study included a total of 57 male patients diagnosed with OUD, 42 male patients diagnosed with MUD, and 72 healthy male controls. The study indicated that the OUD and MUD patients were significantly different from the healthy controls in terms of the 2D:4D ratio, alexithymia, impulsivity, aggression, and ADHD. Compared to healthy controls, 2D:4D ratios, and Dr-I values were lower in OUD and MUD patients. OUD and MUD patients had higher scores of alexithymia, impulsivity, aggression, and ADHD compared to healthy controls. There were statistically significant negative correlations between the right-hand 2D:4D ratios and the ADHD, impulsivity, alexithymia and aggression scores and a significant negative correlation between Dr-I scores and the impulsivity scores of MUD and OUD patients. These findings contribute to the existing literature examining the complex relationship between prenatal testosterone exposure, substance use disorders and related psychological traits.

Abstract
BACKGROUND AND AIMS Poor substance use-related health outcomes after release from prison are common. Identifying people at greatest risk of substance use and related harms post-release would help to target support at those most in need. The Alcohol Smoking and Substance Involvement Screening Test (ASSIST) is a validated substance use screener, but its utility in predicting substance-related hospitalisation post-release is unestablished. We measured whether screening for moderate/high-risk substance use on the ASSIST was associated with increased risk of substance-related hospitalisation. DESIGN A prospective cohort study. SETTING Prisons in Queensland and Western Australia. PARTICIPANTS Participants were incarcerated and within 6 weeks of expected release when recruited. A total of 2585 participants were followed up for a median of 873 days. MEASUREMENTS Baseline survey data were combined with linked unit record administrative hospital data. We used the ASSIST to assess participants for moderate/high-risk cannabis, methamphetamine and heroin use in the 3 months prior to incarceration. We used International Classification of Diseases (ICD) codes to identify substance-related hospitalisations during follow-up. We compared rates of substance-related hospitalisation between those classified as low/no-risk and moderate/high-risk on the ASSIST for each substance. We estimated adjusted hazard ratios (aHR) by ASSIST risk group for each substance using Weibull regression survival analysis allowing for multiple failures. FINDINGS During follow-up, 158 (6%) participants had cannabis-related, 178 (7%) had opioid-related and 266 (10%) had methamphetamine-related hospitalisation. The hazard rates of substance-related hospitalisation after prison were significantly higher among those who screened moderate/high-risk compared with those screening low risk on the ASSIST for cannabis (aHR 2.38, 95% confidence interval [CI] 1.74, 3.24), methamphetamine (aHR 2.23, 95%CI 1.75, 2.84) and heroin (aHR 5.79, 95%CI 4.41, 7.60). CONCLUSIONS Incarcerated people with an Alcohol Smoking and Substance Involvement Screening Test (ASSIST) screening of moderate/high-risk substance use appear to have a significantly higher risk of post-release substance-related hospitalisation than those with low risk. Administering the ASSIST during incarceration may inform who has the greatest need for substance use treatment and harm reduction services in prison and after release from prison.

Abstract
BACKGROUND Substance use and mental distress are known barriers to HIV care engagement among trans women. Less is known about access and utilization of mental health and substance use care among trans women and the relationship between unmet behavioral health needs and HIV viral suppression. We examined the relationship between mental health and substance use on HIV viral load among trans women living with HIV. We also examined the relationship between mental health and substance use services needs with HIV care engagement and having a detectable viral load by comparing engagement in care cascades. METHODS Data are from a 2022 baseline assessment for an intervention with trans women living with HIV (n = 42) in San Francisco. Chi-Squared or Fisher's exact tests were conducted to determine associations between HIV viral load, mental health, and substance use. We also examine characteristics associated with each step in the HIV, mental health, and substance use care cascades. RESULTS Most participants were trans women of color (85.7%), 40 years of age or older (80.9%), with low income (88.1%), and almost half were unstably housed (47.6%). Of the 32 participants who screened positive for depression, anxiety and/or psychological distress, 56.3% were referred for mental health services in the past 12 months. Of those who were referred, 44.4% received mental health services. Of the 26 participants who screened positive for a substance use disorder, 34.6% were referred to substance use services in the past 12 months. Of those referred, 33.3% received substance use services in the past 3 months. Latina trans women had a low referral rate to meet their mental health needs (50%) and only 16.7% of African American/Black trans women who screened positive for a substance use disorder were referred for services, while trans women of other race/ethnicities had high referral and services utilization. No significant results were found between HIV viral load and screening positive for a mental health disorder. Methamphetamine use was statistically associated with having a detectable HIV viral load (p = 0.049). CONCLUSIONS We identified significant unmet mental health and substance use services needs and noted racial/ethnic disparities in the context of high HIV care engagement among trans women living with HIV. We also found that methamphetamine use was a barrier to having an undetectable viral load for trans women living with HIV. To finally end the HIV epidemic, integration of behavioral health screening, linkage, and support are needed in HIV care services for populations most impacted by HIV, especially trans women.

Abstract
In the present study enantioselective high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods were developed for the quantitative determination of 3,4-methylenedioxy-methamphetamine (MDMA) and its major phase-1 metabolites 4-hydroxy-3-methoxyamphetamine (HMA), 4-hydroxy-3-methoxymethamphetamine (HMMA) and 3,4-methylenedioxyamphetamine (MDA) in human plasma, sweat, oral fluid (OF) and urine. The simultaneous separation of all these compounds and their respective enantioseparation was accomplished on two polysaccharide-based chiral columns. The Lux AMP column with a proprietary chiral selector enabled baseline separation of the enantiomers of MDMA, HMA and HMMA while MDA enantiomers could not be separated with this column under the experimental conditions used in this study. The Lux i-Amylose-3 column based on amylose tris(5-chloro-3-methylphenylcarbamate) as chiral selector baseline-separated the enantiomers of MDMA, HMMA and MDA while the enantiomers of HMA could not be separated. Thus, the various samples were analyzed by using both columns alternatively in combinations with acetonitrile containing 25% (v/v) 5 mM ammonium bicarbonate buffer at pH 11.0 as mobile phase. Analysis time was less than 4 min with the Lux AMP column and less than 6 min with the Lux i-Amylose-3 column. Both methods were validated and applied to the enantioselective determination of MDMA and its phase-I metabolites in human biological fluids, and enantioselective metabolism of MDMA was confirmed.

Abstract
Electrochemical sensors have emerged as a new analytical tool for illicit drug detection to facilitate ultrafast and accurate identification of suspicious compounds on-site. Drugs of abuse can be identified using their unique voltammetric fingerprint at a given pH. Today, the right buffer solution is manually selected based on drug appearance, and in some cases, a consecutive analysis in two different pH solutions is required. In this work, we present a disposable microfluidic multichannel sensor system that automatically records fingerprints in two pH solutions (e.g., pH 5 and pH 12). This system has two advantages. It will overcome the manual selection of a buffer solution at the right pH, decrease analysis time, and minimize the risk of human errors. Second, the combination of two fingerprints, the superfingerprint, contains more detailed information about the samples, which enhances the selectivity of the analytical technique. First, real-time pH measurements proved that the sample can be brought to the desired pH within a minute. Subsequently, an electrochemical study on the microfluidic platform with 1 mM illicit drug standards of MDMA, cocaine, heroin, and methamphetamine showed that the characteristic voltammetric fingerprints and peak potentials are reproducible, also in the presence of common cutting agents. Finally, the microfluidic concept was validated with real confiscated samples, showing promising results for the user-friendly identification of drugs of abuse. In short, this paper presents a successful proof-of-concept study of a multichannel microfluidic sensor system to enrich the fingerprints of illicit drugs at pH 5 and pH 12, thus providing a low-cost, portable, and rapid identification system of illicit drugs with minimal user intervention.

Abstract
The opioid and methamphetamine crises in Oregon have a consequential impact on young families, as an increasing number of parents experience substance use disorder (SUD). As parental substance use escalates, the child welfare system (CWS) becomes overwrought with families who have complex needs. The burden placed on families and on the CWS indicates a need for prevention and treatment interventions for parental SUDs. In response to the worst statewide opioid and methamphetamine epidemics in the USA, a Hybrid Type 2 trial of PRE-FAIR-a prevention intervention for parents-is being implemented in five Oregon counties. Establishing strong partnerships within the communities helped identify the need to implement the evidence-based FAIR treatment model alongside PRE-FAIR. A strong focus on implementation includes meeting the needs of communities and establishing the infrastructure necessary for sustainment of the FAIR programs at the provider agencies. Despite implementation efforts to direct toward PRE-FAIR referrals, parents in need of treatment are being referred at a disproportionate rate, as are older parents who fall outside of study-eligibility. Both challenges have delayed the ability to enroll a sufficient number of participants for the prevention trial. This commentary describes the impact of the opioid and methamphetamine epidemics in Oregon as the crises relate to implementing prevention versus treatment interventions-highlighting the importance of addressing community needs and establishing strong partnerships, which has allowed creative strategies to increase PRE-FAIR recruitment.

Abstract
BACKGROUND Childhood trauma is associated with substance use disorders, including methamphetamine use disorder (MUD). Oxytocin, involved in social bonding, stress regulation, and reward processing, may influence addiction vulnerability and impulsivity in individuals with a history of childhood trauma. OBJECTIVE To investigate the relationships among childhood trauma, oxytocin levels, impulsivity, and the age of first methamphetamine use in individuals with MUD. PARTICIPANTS AND SETTING The study included 298 male participants (148 individuals with MUD and 150 healthy controls) from both probation offices and psychiatric clinics. METHODS Childhood trauma was assessed using the Childhood Trauma Questionnaire-Short Form (CTQ-SF), impulsivity with the Barratt Impulsiveness Scale-11 (BIS-11), and plasma oxytocin levels were obtained. RESULTS Individuals with MUD exhibited higher levels of childhood trauma, impulsivity, and lower plasma oxytocin levels compared to healthy controls. Childhood trauma was associated with a younger age of first methamphetamine use, higher impulsivity, and lower oxytocin levels among individuals with MUD. Plasma oxytocin levels partially mediated the relationship between childhood trauma and both the age of first methamphetamine use and impulsivity. Serial mediation analysis demonstrated that oxytocin levels and impulsivity sequentially mediated the relationship between childhood trauma and the age of first methamphetamine use. CONCLUSIONS The findings reveal the complex interplay among childhood trauma, oxytocin, impulsivity, and methamphetamine use, emphasizing the importance of considering these factors in prevention and intervention strategies for MUD. Future research should explore oxytocin and impulsivity-focused interventions to mitigate the effects of childhood trauma and reduce MUD development risk.

Abstract
People with methamphetamine use disorder (MUD) struggle to shift their behaviour from methamphetamine-orientated habits to goal-oriented choices. The model-based/model-free framework is well suited to understand this difficulty by unpacking the computational mechanisms that support experienced-based (model-free) and goal-directed (model-based) choices. We aimed to examine whether 1) participants with MUD differed from controls on behavioural proxies and/or computational mechanisms of model-based/model-free choices; 2) model-based/model-free decision-making correlated with MUD symptoms; and 3) model-based/model-free deficits improved over six weeks in the group with MUD. Participants with MUD and controls with similar age, IQ and socioeconomic status completed the Two-Step Task at treatment commencement (MUD n = 30, Controls n = 31) and six weeks later (MUD n = 23, Controls n = 26). We examined behavioural proxies of model-based/model-free decisions using mixed logistic regression, and their underlying mechanisms using computational modelling. At a behavioural level, participants with MUD were more likely to switch their choices following rewarded actions, although this pattern improved at follow up. At a computational level, groups were similar in their use of model-based mechanisms, but participants with MUD were less likely to apply model-free mechanisms and less likely to repeat rewarded actions. We did not find evidence that individual differences in model-based or model-free parameters were associated with greater severity of methamphetamine dependence, nor did we find that group differences in computational parameters changed between baseline and follow-up assessment. Decision-making challenges in people with MUD are likely related to difficulties in pursuing choices previously associated with positive outcomes.

Abstract
ISSUES Project Stop, a real-time monitoring program for pseudoephedrine-containing medicines, was initiated in 2005 by the Pharmacy Guild of Australia in collaboration with police in the state of Queensland. The program implemented an online database to record pseudoephedrine purchases (and attempted purchases) to prevent large-scale diversion to methamphetamine production. APPROACH This narrative review aims to understand the overall impact of Project Stop, what evidence exists for this kind of intervention in Australia, and what lessons can be learned from its introduction. Systematic database searches were conducted in Embase, PubMed, Web of Science and Google Scholar, with 20 relevant sources selected for inclusion. KEY FINDINGS Project Stop successfully prevented some pseudoephedrine from being diverted from pharmacies to methamphetamine production. The intervention has been most effective in jurisdictions that made the program mandatory. Project Stop was also associated with a temporary decline in clandestine laboratory seizures in Queensland, changes in methamphetamine production methods and reduced voluntary treatment admissions for methamphetamine use. Implementation was not associated with an appreciable effect on secondary indicators, such as methamphetamine production and harmful use. IMPLICATIONS Future applications of a Project Stop model must ensure ongoing impact evaluation, assessment of its effect on individual's drug-related behaviour and combine it with policies that address drug use as a health issue. CONCLUSION Project Stop has been narrowly successful in terms of reducing pseudoephedrine diversion and demonstrates the potential for third-party policing practices directed at the consumer level, in collaboration with healthcare practitioners, rather than only regulating precursor wholesalers.

Abstract
Methamphetamine use is increasing in the Australian population. It has a known association with violent and erratic behaviour and with an increased risk of unnatural deaths. To determine whether victims of homicide have significant exposure to methamphetamine 100 randomly selected de-identified homicide cases from 2012 to 2021 were accessed from the Forensic Science SA (FSSA) Pathology Database to determine the type of homicide and whether methamphetamine was detected in the blood. A total of 76 males and 24 females were found (M:F = 3:1). Of these, 30 victims (30%) had methamphetamine detected in blood, consisting of 26 males and 4 females (M:F = 6:1; male age range 18-53 years, average 36.8 years; female age range 28-63 years average 44.8 years). Levels of methamphetamine ranged from 0.02 to 3.3 mg/L with an average of 0.64 mg/L, with the highest numbers of positive cases occurring in victims of gunshot wounds (45.5%), and the lowest in those with lethal blunt force trauma (23.5%). This study has demonstrated that victims of homicide in an Australian population are more likely to have used methamphetamine than members of the general population. The reasons for this remain unclear although involvement in a drug selling environment may be an important determinant.

Abstract
Methylone (3,4-methylenedioxy-N-methylcathinone) is a rapid-acting entactogen that has been shown to have significant benefits in patients with post-traumatic stress disorder and major depressive disorder and is well tolerated in phase 1 clinical trials. A recent preclinical study reported that methylone produced robust antidepressant-like actions in naïve rats. However, its antidepressant effects on various stress-related psychopathologies and other neuropsychological actions remain unclear. In the present study, we examined the antidepressant-relevant effects of methylone in learned helplessness (LH) and social defeat stress C57BL/6J male mouse models and further explored its sociability-relevant neuropsychological actions. Our results indicate that methylone produces antidepressant-relevant effects on the helpless phenotype, LH-evoked depressive-like behaviors, and psychosocial stress-induced social avoidance, and induced depressive-like behaviors. In addition, methylone was found to enhance social preference and increase various social behaviors, including social contact, sniffing, allogrooming, and following. Moreover, methylone appeared to elevate empathy-like phenotypes and was also found to increase helping-like behavior. Overall, the present results suggest that methylone plays an antidepressant-like role in various stress-relevant psychopathologies and could be an ideal antidepressant candidate. In addition, novel findings on the elevated tendencies of social preference and empathy-like and helping-like phenotypes reveal that methylone may have potential application in patients with social deficits.

Abstract
Addiction is a substantial health concern; craving-the core symptom of addiction-is strongly associated with relapse. Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation technique that reduces cravings by altering cortical excitability and connectivity in brain regions. This systematic review and meta-analysis was conducted (following the PRISMA guidelines) to evaluate the efficacy of tDCS in reducing cravings for substances. Our analysis included 43 randomized, sham-controlled trials involving 1,095 and 913 participants receiving tDCS and sham stimulation, respectively. We analyzed the changes in craving scores and found that tDCS led to a moderate reduction in cravings compared with the sham effects. This effect was particularly pronounced when bilateral stimulation was used, the anodal electrode was placed on the right dorsolateral prefrontal cortex, current intensities ranged from 1.5 to 2 mA, stimulation sessions lasted 20 minutes, and the electrodes size was ≥35 cm². Notably, tDCS effectively reduced cravings for opioids, methamphetamine, cocaine, and tobacco but not for alcohol or cannabis. Our findings indicate tDCS as a promising, noninvasive, and low-risk intervention for reducing cravings for opioids, methamphetamine, cocaine, and tobacco. Additional studies are warranted to refine stimulation parameters and evaluate the long-term efficacy of tDCS in managing substance cravings.

Abstract
BACKGROUND AND OBJECTIVES Comorbidity of substance use disorders and depression is a common phenomenon. It is well known that opioid addiction is neurobiologically distinct from psychostimulant addiction. However, direct comparisons of comorbid depressive symptoms in patients with methamphetamine (METH) use disorder (MAUD) and heroin use disorders (HUD) have been lacking until now. METHODS A total of 353 patients with methamphetamine use disorder, 76 patients with HUD, and 203 healthy controls were recruited. The Beck Depression Inventory (BDI-SF), the Desires for Drug Questionnaire (DDQ) and the short form of the Childhood Trauma Questionnaire (CTQ-SF) were used to measure participants' depressive symptoms, drug craving, and childhood abuse or neglect, respectively. RESULTS The prevalence of depressive symptoms was 35.41% (125/353) in MAUD and 56.57% (43/76) in MAUD, significantly higher than the 22.66% (46/203) in healthy controls. Furthermore, there was a significant difference in the total BDI score between the MAUD and HUD groups (F = 5.02, df = 1, 372, p = .026). Among MAUD, years of education, history of incarceration, month of abstinence and negative reinforcement scores were associated with depressive symptoms (all p < .05). Among HUD, duration of drug use, childhood emotional abuse and sexual abuse were associated with depressive symptoms (all p < .05). CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE The prevalence and correlates of depressive symptoms differ between MAUD and HUD, adding to the existing literature. Therefore, treatment and intervention programs should be designed to address these unique correlates in HUD and MAUD patients.
