Tomsone LE, Neilands R, Kokina K, Bartkevics V, Pugajeva I. Pharmaceutical and Recreational Drug Usage Patterns during and Post COVID-19 Determined by Wastewater-Based Epidemiology. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2024; 21:206. [PMID: 38397695 PMCID: PMC10888181 DOI: 10.3390/ijerph21020206] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Revised: 01/29/2024] [Accepted: 02/05/2024] [Indexed: 02/25/2024]
Abstract
Wastewater-based epidemiology (WBE) was applied to evaluate the consumption trends of pharmaceuticals (i.e., antibiotics, non-steroidal anti-inflammatory drugs, antiepileptics, antihypertensives, and others), as well as recreational drugs (caffeine, alcohol, and nicotine), in Latvia from December 2020 to July 2023. The time period covers both the COVID-19 pandemic and the post-pandemic periods; therefore, the impact of the implemented restrictions and the consequences of the illness in terms of the usage of pharmaceuticals thereon were investigated. Additionally, the seasonality and impact of the seasonal flu and other acute upper respiratory infections were studied. The results revealed that the pandemic impacted the consumption of alcohol, nicotine, and caffeine, as well as several pharmaceuticals, such as antihypertensives, antidepressants, psychiatric drugs, and the painkiller ibuprofen. The findings suggest that the imposed restrictions during the pandemic may have had a negative effect on the population's health and mental well-being. Distinct seasonal trends were discovered in the consumption patterns of caffeine and alcohol, where lower use was observed during the summer. The seasonal consumption trends of pharmaceuticals were discovered in the case of antibiotics, the antiasthmatic drug salbutamol, and the decongestant xylometazoline, where higher consumption occurred during colder seasons.

Greer A, Xavier J, Loewen OK, Kinniburgh B, Crabtree A. Awareness and knowledge of drug decriminalization among people who use drugs in British Columbia: a multi-method pre-implementation study. BMC Public Health 2024; 24:407. [PMID: 38331771 PMCID: PMC10851533 DOI: 10.1186/s12889-024-17845-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Accepted: 01/22/2024] [Indexed: 02/10/2024] Open
Abstract
BACKGROUND In January 2023, British Columbia implemented a three-year exemption to Controlled Drugs and Substances Act, as granted by the federal government of Canada, to decriminalize the personal possession of small amounts of certain illegal drugs. This decriminalization policy, the first in Canada, was announced in response to the overdose emergency in British Columbia as a public health intervention that could help curb overdose deaths by reducing the impact of criminalization and increasing access to health and social services through stigma reduction. METHODS The current multi-method study examines people who use drugs' awareness and knowledge of British Columbia's decriminalization model through cross-sectional quantitative surveys and qualitative interviews among people who use drugs from September-November 2022, immediately prior to the implementation of decriminalization. RESULTS Quantitative findings show that two-thirds (63%) of people who use drugs were aware of the policy, but substantial knowledge gaps existed about the legal protections afforded (threshold amount, substances included, drug trafficking, confiscation). The qualitative findings suggest that people who use drugs misunderstood the details of the provincial decriminalization model and often conflated it with regulation. Results suggest that information sharing about decriminalization were minimal pre-implementation, highlighting areas for knowledge dissemination about people who use drugs' rights under this policy. CONCLUSIONS Given that decriminalization in British Columbia is a new and landmark reform, and that the success of decriminalization and its benefits may be undermined by poor awareness and knowledge of it, efforts to share information, increase understanding, and empower the community, may be required to promote its implementation and benefits for the community.

Abstract
Background: Illicit substance sales facilitated by social media platforms are a growing public health issue given recent increases in overdose deaths, including an alarming rise in cases of fentanyl poisoning. However, little is known about how online users evaluate what features of social media posts convey safety, which can influence their intent to source illicit substances. Objectives: This study adapts conjoint analysis which assessed how attributes of social media posts (i.e., features) influence safety evaluations of mock posts selling illicit substances. 440 participants were recruited online for self-reporting use or purchase of controlled substances or prescription medicines recreationally. The following attributes were tested: drug packaging, drug offerings, profile photo of seller, payment info provided, and use of emojis. Results: Packaging was ranked the most important attribute (Average Importance =43.68, Offering=14.94, Profile=13.86, Payment=14.11, Emoji=13.41), with posts that displayed drugs in pill bottles assessed as the most safe. Attribute levels for advertising multiple drugs, having a blank profile photo, including payment information, and including emojis also ranked higher in perceived safety. Rankings were consistent across tested demographic factors (i.e., gender, age, and income). Survey results show that online pharmacies were most likely to be perceived as safe for purchasing drugs and medications. Additionally, those who were younger in age, had higher income, and identified as female were more likely to purchase from a greater number of platforms. Conclusions: These findings can assist in developing more precise content moderation for platforms seeking to address this ongoing threat to public safety.

PLoS One 2024; 19:e0294740. [PMID: 38315674 PMCID: PMC10843129 DOI: 10.1371/journal.pone.0294740] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2023] [Accepted: 11/07/2023] [Indexed: 02/07/2024] Open
Abstract
Increasing illicit drug use is one of the main problems in most countries or societies. Monitoring heavy metals and trace elements in this vulnerable group seems to be necessary. Therefore, we assessed the urinary trace element and toxic metals/metalloids concentrations (Zinc (Zn), Iron (Fe), Copper (Cu), Chromium (Cr), Lead (Pb), Cadmium (Cd), Arsenic (As), Nickel (Ni), and Mercury (Hg)) in opium, tramadol, and cannabis users compared to healthy subjects. In this cross-sectional study, patients with substance use disorder (SUD) (n = 74) were divided into four groups: cannabis, tramadol, opium, and mixed (simultaneous use of more than one of the three studied substances), along with a healthy group (n = 60). Urine samples were prepared by dispersive liquid-liquid microextraction method so that heavy metals/metalloids could be measured by ICP-MS. The mean urinary concentration of Cu (48.15 vs. 25.45; 89.2%, p<0.001), Hg (1.3 vs. 0.10; 1200%, p < 0.001), and Zn (301.95 vs. 210; 43.8%, p < 0.001) was markedly lower among patients with SUD. The mean urinary concentration of other elements including As (1.9 vs. 4.1; 115.8%), Cd (0.1 vs. 1.10; 1000%), Cr (6.80 vs. 11.65; 71.3%), Ni (2.95 vs. 4.95; 67.8%), and Pb (1.5 vs. 7.9; 426.6%) were significantly higher among patients with SUD compared to healthy subjects. When sub-groups were compared, no significant differences were observed between their trace element levels (Kruskal-Wallis test, p > 0.05). This can be an indication that regardless of the type of drug, the levels of trace elements are changed with respect to healthy individuals. Our results showed that illicit drug use causes changes in urinary trace element/heavy metal/metalloid levels and highlights the need for monitoring heavy metals and trace elements in individuals with substance use disorder. Assessment of different elements in biological samples of drug dependents may be useful for implementing new prevention and treatment protocols. In case of changes in their levels, complementary recommendations, attention to diet, and periodic assessment of toxic metal levels within treatment programs will be needed.

Racial/Ethnic Disparities in Club Drug Use, Situational Club Drug Use during Sex, and Sexual Risk Behaviors among Alcohol-Using Men Who Have Sex with Men (MSM) in San Francisco. Subst Use Misuse 2024; 59:895-901.

Abstract
BACKGROUND Club drug use-including 3,4-Methylenedioxymethamphetamine, ketamine, crack/cocaine, hallucinogens, gamma hydroxybutyrate, volatile nitrites, and methamphetamine-has been linked to sexual risk behaviors among MSM. Few studies examine how the use of club drugs and the association between club drug use during sex and sexual risk may differ by race/ethnicity. METHODS Using data from a cross-sectional study among alcohol-using MSM in San Francisco (n = 252), we examined the associations between the interaction of race/ethnicity and club drug use during sex, and the following behavioral outcomes: any condomless anal intercourse (CAI), insertive CAI, receptive CAI, and any serodiscordant sex in the past six months. All models controlled for income, HIV status, relationship status, age, and current use of a biomedical HIV prevention tool (i.e., Pre-Exposure Prophylaxis [PrEP] or antiretroviral therapy). RESULTS There were significant racial differences in club drug use (p < 0.001) and club drug use during sex (p = 0.01). Asian/Pacific Islander (API) and Latino participants reported using club drugs the most at 78.8% and 79%, respectively. Among users of club drugs, club drug use during sex was most common among Black (100%), and Latino MSM (93%). Significant interactions between race/ethnicity and club drug use during sex were observed for CAI (p = 0.02), insertive CAI (p = 0.01), and receptive CAI (p = 0.01). API participants who used club drug during sex had higher odds of reporting CAI (aOR = 15.27, CI = 1.50-155.34), insertive CAI (aOR = 21.11, CI = 2.04-218.10), and receptive CAI (aOR = 21.11, CI = 2.04-218.10). CONCLUSIONS Given the differing rates of club drug use during sex by race/ethnicity and the role race/ethnicity plays in modifying the relationships between club drug use during sex and sexual risk behaviors, culturally-tailored interventions may be needed to address the needs of ethnically-diverse, club drug-using MSM.

Abstract
We sought to characterize overdose and non-overdose mortality among PLWH amidst the illicit drug toxicity crisis in British Columbia, Canada. A population-based analysis of PLWH (age ≥19) in British Columbia accessing healthcare from April 1996 to March 2017 was conducted using data from the Seek and Treat for Optimal Prevention of HIV/AIDS (STOP HIV/AIDS) cohort linkage. Underlying causes of deaths were stratified into overdose and non-overdose causes. We compared (bivariate analysis) health-related characteristics and prescription history between PLWH died of overdose and non-overdose causes between April 2009 and March 2017. Among 9,180 PLWH, we observed 962 deaths (142 [14.7%] overdoses; 820 [85.2%] other causes). Compared to those who died from other causes, those who died of overdose were significantly younger (median age [Q, Q3]: 46 years [42, 52] vs. 54 years [48, 63]); had an indication of chronic pain (35.9% vs. 27.1%) and hepatitis C virus (64.8% vs. 50.4%), but fewer experienced hospitalization in the year before death. PLWH who died were most likely to be prescribed with opioids (>50%) and least likely with opioid agonist therapy (<10%) in a year before death. These findings highlight the syndemic of substance use, HCV, and chronic pain, and how the crisis is unqiuely impacting females and younger people.

Abstract
OBJECTIVE To evaluate self-reported substance user profiles for individuals with migraine and compare these to the general population. BACKGROUND There is increasing attention to lifestyle influences such as substance use as presumed migraine triggers. METHODS Data on substance use were collected by survey in a large migraine cohort and from the biannual survey in the general Dutch population for substances. A representative cohort of Dutch patients with migraine (n = 5176) and the Dutch general population (n = 8370) was included. Patients with migraine were subdivided into episodic (EM) and chronic migraine (CM). Substance consumption was compared between the general population and patients with migraine, and between migraine subgroups after standardization for sex and level of education. RESULTS Included patients with migraine were 83.4% female (4319/5176) and had a mean (standard deviation) age of 44.8 (11.3) years. Patients with migraine reported less illicit drug use (odds ratio [OR] 0.48, 95% confidence interval [CI] 0.42-0.55; p < 0.001), less current and lifetime smoking (OR 0.60, 95% CI 0.55-0.65; p < 0.001 and OR 0.75, 95% CI 0.71-0.79; p < 0.001), and less current alcohol consumption (OR 0.66, 95% CI 0.62-0.70; p < 0.001) compared with the general population. Prevalence of substance use was compared between CM and EM participants and showed higher illicit drug use (OR 1.73, 95% CI 1.11-2.69; p = 0.011), higher current smoking (OR 1.61, 95% CI 1.22-2.11; p < 0.001) but less alcohol use (OR 0.54, 95% CI 0.43-0.68; p < 0.001) for participants with CM compared with EM. No differences were found for a history of smoking (OR 1.18, 95% CI 0.92-1.50, p = 0.19). CONCLUSIONS Individuals with migraine are less likely to use illicit drugs, smoke, or drink alcohol compared with the general population. Patients with CM less often consume alcohol, while they more often use illicit drugs and smoke compared to those with EM.

Abstract
This article draws from qualitative interviews to provide the first in-depth exploration of reasons for engaging in chemsex in the Philippines. It articulates the many forms that drugs assume as pampalibog, or enhancers of libido, demonstrating the multidimensional pleasures of chemsex along overlapping sensorial and affective planes. By showing the inextricability of the corporeal to the affective, and of the emotional to the erotic, we contend that chemsex also involves the embodied and performed attainment of pleasure. As such, chemsex is both central to modern sexual scripts yet also a negotiable aspect of any sexual encounter. In constructing this rare account of drug use in settings of pleasure in the Philippines, we situate chemsex within a historical pattern of bodily tinkering and, more significantly, demystify people who use drugs by departing not only from global public health's pathologising approach to chemsex, but also from the scholarly tendency to locate drug use in the country within scenes of hardship and marginalisation.

Abstract
Since the early 2000s, there has been a turmoil on the global illicit cannabinoid market. Parallel to legislative changes in some jurisdictions regarding herbal cannabis, unregulated and cheap synthetic cannabinoids with astonishing structural diversity have emerged. Recently, semi-synthetic cannabinoids manufactured from hemp extracts by simple chemical transformations have also appeared as recreational drugs. The burst of these semi-synthetic cannabinoids into the market was sparked by legislative changes in the United States, where cultivation of industrial hemp restarted. By now, hemp-derived cannabidiol (CBD), initially a blockbuster product on its own, became a "precursor" to semi-synthetic cannabinoids such as hexahydrocannabinol (HHC), which appeared on the drug market in 2021. The synthesis and cannabimimetic activity of HHC were first reported eight decades ago in quest for the psychoactive principles of marijuana and hashish. Current large-scale manufacture of HHC is based on hemp-derived CBD extract, which is converted first by cyclization into a Δ8 /Δ9 -THC mixture, followed by catalytic hydrogenation to afford a mixture of (9R)-HHC and (9S)-HHC epimers. Preclinical studies indicate that (9R)-HHC has THC-like pharmacological properties. The animal metabolism of HHC is partially clarified. The human pharmacology including metabolism of HHC is yet to be investigated, and (immuno)analytical methods for the rapid detection of HHC or its metabolites in urine are lacking. Herein, the legal background for the revitalization of hemp cultivation, and available information on the chemistry, analysis, and pharmacology of HHC and related analogs, including HHC acetate (HHC-O) is reviewed.

Abstract
The aim of this study was to investigate the association between maternal and paternal licit and illicit drug use, smoking and drinking and autism spectrum disorder (ASD). We conducted a case-control study with children and adolescents diagnosed with ASD and neurotypical individuals. The data were collected using a semi-structured questionnaire administered during interviews with the children's mothers or guardians. The following variables were analyzed: child sex and age; maternal and parental age; use of medicines before and during pregnancy; classes of medicines used during pregnancy; maternal and paternal smoking; maternal and paternal drinking; maternal and paternal illicit drug use. The data were analyzed using logistic regression and crude and adjusted odds ratios (OR). After adjustment, the results showed an association between maternal use of antipyretics/pain killers during pregnancy (OR = 2.26; 95%CI 1.29-3.95; p < 0.040) and ASD. No association was found between maternal and paternal smoking, drinking and illicit drug use before and during pregnancy and ASD. The findings suggest that the development of ASD is influenced by environmental factors.

Abstract
Canada has been experiencing a prolonged public health-crisis of high rates of overdose deaths caused by exceptionally potent/toxic, illicit opioid use. While many key features of this drug death epidemic are well-documented, several idiosyncratic aspects with relevance for public health-oriented interventions are not adequately recognised. These include: (i) the discrepant opioid patterns pan-Canada, with large majorities of opioid deaths caused by illicit fentanyl drugs in Western, but not Eastern regions where prescription-type opioid prevail; (ii) the environments of overdose deaths, where vast majorities occur in 'residential' or other shelter-type settings, presenting barriers for emergency interventions rather than health protection; and (iii) shifting drug use modes, where now majorities of overdose deaths are associated with drug 'inhalation' (instead of 'injection') in contexts of potent/toxic drug supply. We briefly describe these factors and related implications for intervention programming towards an improved response to the drug death-crisis.

Abstract
INTRODUCTION Investigating drug trends among Australian gay and bisexual men (GBM) is crucial for understanding levels of use and the potential for harm, including HIV transmission risk. METHOD Using repeated, national, cross-sectional survey data collected between 2012 and 2021 (69,567 surveys), trends of recent (previous 6 months) and frequent (weekly) drug use were analysed, using logistic regression models. The last round of data from each jurisdiction (6709 surveys) was used to compare GBM who reported no use, infrequent (less than weekly) use and frequent (at least weekly) use of party drugs to investigate the association between party drug use and HIV transmission risk, using multinomial logistic regression models. RESULTS There was a significant upward trend in any recent drug use (from 58.4% in 2012 to 64.1% in 2021; p < 0.001). Frequent party drug use remained a minority practice over the period (consistently less than 3%). In cross-sectional analysis, frequent party drug users were more likely to report behaviours with HIV transmission risks, such as condomless anal intercourse without biomedical prevention strategies (30.0% vs. 13.1%; adjusted relative risk ratio [aRRR], 2.08; 95% CI, 1.24-3.47), weekly group sex (16.3% vs. 0.6%; aRRR, 12.36; 95% CI, 5.75-26.56) and more than 20 recent sexual partners (42.5% vs. 5.0%; aRRR, 21.44; 95% CI, 5.82-78.89), compared with GBM who did not use party drugs. DISCUSSION AND CONCLUSION Our findings suggest that the frequent use of party drugs remains a marker of HIV transmission risk among Australian GBM, despite the increased adoption of biomedical HIV prevention strategies over the past few years.

Abstract
Background: Adult studies have demonstrated that polysubstance use increases HIV acquisition risk through increased sexual behaviors, however, few studies have examined polysubstance in young Black and Latinx sexual minority men (SMM) and transgender women (TW). Methods: We used cross-sectional data from 466 young Black and Latinx SMM and TW living in four high HIV-burden US cities enrolled in the PUSH Study, a status-neutral randomized control trial to increase HIV prevention and treatment adherence. We examined data for patterns of polysubstance use comparing age differences of use and explored associations between substance use and sexual partnership factors - inconsistent condom use, pressure to have condomless anal sex, and older partner, using bivariate and multivariate analyses. Results: Most participants described prior substance use with alcohol and cannabis being most common (76% each) and 23% described other illicit drug use, including stimulants, cocaine, hallucinogens, sedatives, opioids, and inhalants. Polysubstance use was common with nearly half (47%) of participants reporting alcohol and cannabis use, 20% reporting alcohol, cannabis, and one other illicit drug use, and 19% reporting alcohol or cannabis use plus one other illicit drug use. Polysubstance use was associated with greater adjusted odds of pressure to have condomless anal sex, older partner (>5 years older), and inconsistent condom use. Conclusions: Associations of polysubstance use with sexual practices and sexual partnerships that are known predictors of HIV acquisition or transmission among Black and Latinx SMM and TW underscore the need for combination interventions that include substance use treatment alongside antiretroviral-based and partner-based HIV prevention and treatment interventions.Trial Registration: ClinicalTrials.gov Identifier: NCT03194477.

Abstract
BACKGROUND Use of legal and illegal muscle-building drugs and dietary supplements has been linked to many adverse health and social outcomes. Research has shown that social media use is associated with the use of these drugs and dietary supplements; however, it remains unknown whether social media companies have specific policies related to the content and advertising of muscle-building drugs and dietary supplements on their platforms. Therefore, this study aimed to assess the content and advertising policies of eight popular social media companies related to muscle-building drugs and dietary supplements. METHODS Content and advertising policies for YouTube, TikTok, Instagram, Snapchat, Facebook, Twitter, Twitch, and Reddit were analyzed in November 2022 to determine whether there were any provisions related to legal (e.g., whey protein) and illegal (e.g., anabolic-androgenic steroids) muscle-building drugs and dietary supplements. Policies were classified as either none, restricted, or prohibited. RESULTS All eight social media platforms had explicit policies prohibiting user-generated content and advertising of illicit drugs and substances (e.g., anabolic-androgenic steroids). User-generated content and advertising policies related to legal muscle-building dietary supplements across the platforms varied; however, none of the eight social media companies had a specific policy regarding user content. CONCLUSIONS Findings underscore the need for stronger social media content and advertising policies related to legal muscle-building dietary supplements.

Abstract
BACKGROUND Cannabis use is associated with outcomes like income, legal problems, and psychopathology. This finding rests largely on correlational research designs, which rely at best on statistical controls for confounding. Here, we control for unmeasured confounders using a longitudinal study of twins. METHOD In a sample of 4,078 American adult twins first assessed decades ago, we used cotwin control mixed effects models to evaluate the effect of lifetime average frequency of cannabis consumption measured on substance use, psychiatric, and psychosocial outcomes. RESULTS On average, participants had a lifetime cannabis frequency of about one to two times per month, across adolescence and adulthood. As expected, in individual-level analyses, cannabis use was significantly associated with almost all outcomes in the expected directions. However, when comparing each twin to their cotwin, which inherently controls for shared genes and environments, we observed within-pair differences consistent with possible causality in three of the 22 assessed outcomes: cannabis use disorder symptoms (βW-Pooled = .15, SE = .02, p = 1.7 × 10-22), frequency of tobacco use (βW-Pooled = .06, SE = .01, p = 1.2 × 10-5), and illicit drug involvement (βW-Pooled = .06, SE = .02, p = 1.2 × 10-4). Covariate specification curve analyses indicated that within-pair effects on tobacco and illicit drug use, but not cannabis use disorder, attenuated substantially when covarying for lifetime alcohol and tobacco use. CONCLUSIONS The cotwin control results suggest that more frequent cannabis use causes small increases in cannabis use disorder symptoms, approximately 1.3 symptoms when going from a once-a-year use to daily use. For other outcomes, our results are more consistent with familial confounding, at least in this community population of twins. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Abstract
Phencyclidine (PCP), a dissociative anesthetic, is a commonly abused recreational drug. In the 1950s, initially tested as an intravenous anesthetic, PCP was discontinued for clinical use due to its severe adverse effects. Since then, it has gained popularity as a recreational drug due to its ability to induce hallucinations and alter perception. PCP can be detected in urine, serum, or plasma by immunoassays and quantified and its presence confirmed by gas or liquid chromatography-mass spectrometry. In the method described here, a deuterated internal standard is added to the sample and the drug is extracted under alkaline conditions. Analysis is conducted using gas chromatography-mass spectrometry (GC-MS). Selected ion monitoring is used for quantitation of PCP.

Abstract
OBJECTIVES We aim to quantify disparities in substance-related acute events (i.e. hospitalizations and deaths for substances, including alcohol, cannabis, opioids, narcotics, and/or illicit drugs) across sexual orientations based on health administrative data. STUDY DESIGN This was a longitudinal analysis from six waves of the Canadian Community Health Survey (2009-2014) linked to hospitalization/mortality data in Ontario, Canada. METHODS The study sample consisted of survey respondents aged ≥15 (weighted n = 15,406,000) who provided a valid response to the question about sexual orientation. The primary outcome was substance-related acute events, including hospitalizations and deaths due to alcohol, cannabis, opioids, narcotics, and/or illicit drugs. Disparities in substance-related acute events across sexual orientation and gender were examined using flexible parametric survival analysis. RESULTS Bisexual women had hazard ratios of 2.46 (95% confidence interval: 1.46-4.15) for any substance-related acute event and 2.67 (95% confidence interval: 1.42-5.00) for non-alcohol substance acute events compared to heterosexual women. Lesbian women did not exhibit significant differences in acute event risk compared to heterosexual women. Gay and bisexual men demonstrated elevated but not statistically significant risks compared to heterosexual men. CONCLUSIONS Bisexual women face higher risks of substance-related acute events, potentially due to self-medication of unique stressors brought on by discrimination and isolation. Enhanced education and training for healthcare professionals are essential to increase awareness and sensitivity toward the heightened substance use risk among lesbian, gay, and bisexual individuals. Targeted interventions aimed at reducing substance use problems among bisexual individuals warrant increased funding and research.

Abstract
BACKGROUND Cigarette smoking is common among pregnant women with substance use disorders (SUD) and may contribute to more adverse health consequences for the infant than alcohol and illicit drug use. However, most studies focused on stopping illicit drug use and paid little attention to cigarette smoking in pregnant women with SUD. PURPOSE To identify predictors of current smoking among pregnant women with SUD, given past-month psychological distress, alcohol use and illicit drug use, the receipt of past-year mental health and substance use treatment controlling for potential confounders. METHODS Secondary analysis of cross-sectional data from the National Survey on Drug Use and Health (NSDUH) 2015-2019 was conducted. The NSDUH included 3,540 pregnant women aged 18-44 years; among them were 195 lifetime smokers with SUD. Multiple logistic regression modeling was used to examine the probability of prenatal smoking. RESULTS Sixty-one percent of pregnant women with SUD reported current cigarette smoking. The likelihood of prenatal smoking increased with a higher level of past-month psychological distress (Adjusted Odds Ratio [AOR] 1.14; 95% Confidence Interval [CI]: 1.02-1.28), past-month illicit drug use (AOR: 5.68; 95% CI: 1.59-20.21), and past-year substance use treatment receipt (AOR: 5.73; 95% CI: 1.88-17.45). CONCLUSION The receipt of substance use treatment markedly increased the probability of smoking in pregnant women with SUD. Treatment and policy initiatives are required to address and integrate cigarette smoking within other substance use treatment modalities for pregnant women with SUD.

Abstract
We conducted a nested case-control study within a cohort with the aim of studying the association between illicit drug use and congenital syphilis (CS). Cases were diagnosed based on treponemal and non-treponemal tests conducted both in the mother and the newborn (NB). Multivariate analysis with logistic regression was performed. A total of 6171 births with a mean gestational age of 37.8 weeks were recorded and 62 CS events were diagnosed (incidence 10.5 events/1000 NB). Associated maternal factors were illicit drug use (OR 14.08, 95% CI 1.19-166.6), <5 prenatal visits (OR 2.9, 95% CI 1.12-7.53), more than two sexual partners (OR 3.76, 95% CI 1.62-8.71) and professional education level (OR 0.06, 95% CI 0.005-0.85). Among the mothers of the cases presented, the prevalence of illicit drug use was 22.6% and the most frequent drugs were methamphetamines and cannabis.

Abstract
Sudden death could occur after assumption of illicit drugs for recreational purposes in adults or after intoxication in children, and toxicological testing would help identify the cause of the death. Analytical methods sensitive and specific for the quantification of a great number of drugs and metabolites in at least 2 matrices should be used. Bile, collected postmortem, may be considered a specimen alternative to blood and urine to perform toxicological testing because of its extended detection window. The present study proposed a LC-MS/MS method to quantify 108 drugs and metabolites in bile. Compounds belonging to the drugs of abuse classes of amphetamines, benzodiazepines, cocaine derivatives, barbiturates, opioids, z-drugs, and psychedelics were analyzed. The sample preparation is simple and does not require solid-phase extraction. The proposed method showed an appropriate selectivity, specificity, accuracy, and precision of the calibrators and quality controls tested (precision < 15%; accuracy < 100 ± 15%). The sensitivity allowed to identify low amounts of drugs (e.g., morphine limit of detection = 0.2 µg/L; limit of quantification = 1.1 µg/L). There is no significant matrix effect, except for buprenorphine and 11-Nor-9-carboxy-Δ9-tetrahydrocannabinol. Carry-over was not present. Analytes were stable at least for 1 month at - 20 °C. Analyzing 13 postmortem specimens, methadone (50%), and cocaine (37.5%) resulted to be the most prevalent consumed substances; the concentrations quantified in bile resulted to be higher than the ones in blood suggesting bile as a potential new matrix for identifying illicit drugs and their metabolites.

Abstract
BACKGROUND Illegal drug use is a public health concern with far-reaching consequences for people who use them and for society. In Sweden, the reported use of illegal drugs has been growing and the number of drug-induced deaths is among the highest in Europe. The aim of this study was to provide a comprehensive and up-to-date estimation of the societal costs of illegal drug use in Sweden, relying as much as possible on registry and administrative data. METHODS A prevalence-based cost-of-illness study of illegal drug use in Sweden in 2020 was conducted. A societal approach was chosen and included direct costs (such as costs of health care, social services, and the criminal justice system), indirect costs (such as lost productivity due to unemployment and drug-induced death), and intangible costs (such as reduced quality of life among people who use drugs and their family members). Costs were estimated by combining registry, administrative, and survey data with unit cost data. RESULTS The estimated societal costs of illegal drug use were 3.7 billion euros in 2020. This corresponded to 355 euros per capita and 0.78 % of the gross domestic product. The direct and intangible costs were of similar sizes, each contributing to approximately 40 % of total costs, whereas indirect costs contributed to approximately 20 %. The largest individual cost components were reduced quality of life among people who use drugs and costs of the criminal justice system. CONCLUSION Illegal drug use has a negative impact on the societal aim to create good and equitable health in Sweden. The findings call for evidence-based prevention of drug use and treatment for those addicted. It is important to address the co-morbidity of mental ill-health and drug dependence, to develop low-threshold services and measures for early prevention among children and young adults, as well as to evaluate laws and regulations connected to illegal drug use.

Abstract
INTRODUCTION The proliferation of fentanyl and its analogs in illegal, unregulated drug markets remains a major driver of the overdose crisis in North America. Drug checking services have been implemented as a harm reduction strategy to address the crisis. However, little is known about their potential utility as a mechanism for monitoring population-level risk of overdose stemming from changing fentanyl concentration in unregulated drugs over time. Therefore, this study assessed the relationship between median fentanyl concentration in expected opioid drug checking samples and the death rate due to illicit drug toxicity over time in Vancouver, Canada. METHODS Monthly population-based rates of death due to illicit drug toxicity were drawn from provincial coroner records. Monthly median percent fentanyl concentration was calculated using a validated quantification model from point-of-care Fourier-transform infrared spectra among expected opioid samples that tested positive for fentanyl at community drug checking services. A time-series analysis using generalized additive modeling was conducted to examine the association between monthly median fentanyl concentration and monthly death rate due to illicit drug toxicity, controlling for calendar month. Analyses were conducted in 2021-2022. RESULTS Between January 2019 and October 2020, 577 deaths due to illicit drug toxicity occurred in Vancouver, and the observed monthly rate ranged from 1.75 to 7.65 deaths per 100,000 population. A significant, positive association was observed between monthly median fentanyl concentration and monthly death rate due to illicit drug toxicity, adjusting for calendar month (chi-square=52.21, p<0.001). CONCLUSIONS Findings suggest a role for point-of-care drug checking as a tool for monitoring evolving overdose risk at the population level.

Abstract
INTRODUCTION New Zealand has a unique illicit drug market, gay cultures and drug use patterns. Minimal attention has been given to how drug use shapes sexual practice, especially in the era of biomedical HIV prevention among gay and bisexual men (GBM). METHODS An online cross-sectional study of GBM ('Flux NZ') adapted from an Australian study was undertaken to explore connections between drug use, sexual practice, health and community. We describe drug use patterns, then identify three discrete groups determined by intensity of recent (past 6 months) sexual practice: no recent sex, recent sex and recent sexualised drug use. We examine factors associated with these groups and identify factors independently predicting sexualised drug use. RESULTS Of 739 participants, almost a third had engaged in group sex (29%), 17.5% were taking pre-exposure prophylaxis (PrEP), 6.5% were HIV positive. Overall, 59.5% had recently used illicit drugs (16.9% methylenedioxymethamphetamine, 6% methamphetamine, 3.3% gamma-hydroxybutyrate acid, 1.4% ketamine). Sexualised drug use was common (35.7%). Those engaged in sexualised drug use were connected to gay community and had a high uptake of biomedical HIV prevention. Independent predictors of sexualised drug use included being sexually adventurous, knowing their HIV status, having more than 10 recent sexual partners, engaging in group sex and sex at a sex-on-site venue. DISCUSSION AND CONCLUSIONS Many GBM engaging in sexualised drug use manage HIV transmission risks through regular testing, PrEP and HIV treatment. HIV prevention efforts should target GBM with less intensive sexual behaviour but who may be at comparatively higher risk of HIV transmission.
