RESUMEN
The recreational use of cannabis products has risen considerably worldwide over the past decade. As the cannabis legal market grows, a critical challenge has been to make substantiated claims about the benefits and adverse health problems triggered by cannabis exposure. Despite accumulating evidence from animal studies demonstrating the role of cannabinoids on bone metabolism, there are conflicting results in clinical literature regarding their effects on bone health outcomes.We undertook a systematic review to assess the evidence for the safety of cannabis use on bone health. We searched the databases MEDLINE, EMBASE, Cochrane Library, and Web of Science up to March 2023 for studies evaluating the effect of the recreational use of cannabis on the bone mineral density (BMD) of adults.Among the 2620 studies reviewed, three cross-sectional studies and one randomized controlled trial comprised 4032 participants from 18 to 60 years who met the inclusion criteria. Two studies showed that cannabis exposure decreased BMD, while the other 2 indicated no alteration. Despite the different study designs, the included studies showed a low risk of bias according to the Joanna Briggs Institute tool.Eligible studies present differences in cannabis products, administration routes, and exposure determination. Further longitudinal research is needed to establish multiple clinical predictors associated with potentially negative consequences of cannabis exposure, especially in vulnerable populations such as elderly individuals.

Homoprejudiced violence is a type of aggression against an individual or a community based on their actual or perceived sexual orientation. It may be linked to risks of acquiring HIV/STI via psychosocial variables. This study explored the association between homoprejudiced violence experiences and high-risk sexual behaviors, and potential psychosocial mediators. Using cross-sectional survey data collected in China through Blued among men who have sex with men (MSM) in January 2021, this study conducted multiple mediation analyses. Standard instruments were used to collect data on depressive symptoms in the last two weeks (PHQ-9), recreational drug usage in the last three months, and ever experiencing homoprejudiced violence (12-item survey instrument). Dependent variables were having condomless anal sex and having three or more sexual partners in the last three months. Among 1828 MSM, nearly half (847, 46%) had experienced homoprejudiced violence. Twenty-three percent (427) reached a score that suggested moderate or severe depression and 35% (644) had used recreational drugs. In the last three months, 40% (731) had condomless anal sex and 34% (626) had three or more sexual partners. The indirect mediational coefficients through depression on condomless anal sex and multiple sexual partners were 0.04 (95% CI: [0.02, 0.07]) and 0.02 (95% CI: [0.001, 0.05]), respectively. The indirect mediational coefficient of homoprejudiced violence experience on multiple sexual partners through recreational drug use was 0.05 (95% CI: [0.03, 0.08]). These findings suggest that more comprehensive interventions are needed to address the syndemic of homoprejudiced violence, mental health issues, and HIV/STI-related risks.

We present the development of an electrochemical paper-based analytical device (ePAD) for the detection of methamphetamine. Methamphetamine is a stimulant that young people use as an addictive narcotic, and it must be detected quickly since it may be hazardous. The suggested ePAD has the advantages of being simple, affordable, and recyclable. This ePAD was developed by immobilizing a methamphetamine-binding aptamer onto Ag-ZnO nanocomposite electrodes. The Ag-ZnO nanocomposites were synthesized via a chemical method and were further characterized via scanning electron microscopy, Fourier transform infrared spectroscopy, and UV-vis spectrometry in terms of their size, shape, and colloidal activity. The developed sensor showed a limit of detection of about 0.1 µg/mL, with an optimum response time of about 25 s, and its extensive linear range was between 0.01 and 6 µg/mL. The application of the sensor was recognized by spiking different beverages with methamphetamine. The developed sensor has a shelf life of about 30 days. This cost-effective and portable platform might prove to be highly successful in forensic diagnostic applications and will benefit those who cannot afford expensive medical tests.

BACKGROUND/AIM: Evidence on the risk of injury at concerts is scant. The aim of this study was to collect data on general and dental injuries incurred by concertgoers in Switzerland and to investigate whether the frequency of accidents was related to music genre, gender and consumption of alcohol. MATERIALS AND METHODS: A questionnaire-based, cross-sectional study comprising 451 concertgoers in Switzerland was conducted on the timeframe January 2019 to February 2021. The survey gathered data on general and dental injuries, alcohol consumption and drug use. The statistical analysis included Fisher's exact tests, chi-squared tests, rank sum tests and logistic regressions (α = .05). RESULTS: There were 28.8% of respondents who reported an injury incurred at a concert. Contusion was the most prevalent injury, accounting for 33.8% of all injuries. Legs were the most commonly injured body part (34.6%). Injuries to their mouth/lips/teeth were reported by 17.7% of respondents. Dental injuries, accounting for 4.6% of all reported injuries, comprised four tooth fractures, one lateral luxation and one avulsion. The risk of injury while attending punk rock concerts was 8.6 times higher than for pop concerts (p < .001). In comparison with pop concerts, metal and rock concerts had an increased risk of injury by factors of 5.1 and 2.3, respectively (p ≤ .029). Neither gender nor drug use had a significant effect on the injury risk (p ≥ .3). Heavy alcohol consumption (>5 standard glasses) increased the risk of injury by a factor of 2.3 (p = .028). CONCLUSIONS: This study suggests that concert attendees at rock, metal and punk concerts face an increased risk of injury, which is likely due to the frequency of aggressive dance styles such as moshing. Heavy alcohol consumption leads to a greater risk of injury at concerts.

OBJECTIVES: Chemsex has been reported among men who have sex with men (MSM) living with HIV. There have been concerns about potentially harmful drug-drug interactions between chemsex drugs and antiretroviral therapy (ritonavir and cobicistat). We aimed to describe the prevalence and patterns of chemsex users in our HIV clinic population and to evaluate antiretroviral prescribing among chemsex users. METHODS: We undertook a cross-sectional study of patients attending our HIV clinic between January 2019 and December 2020. We collected data on patients who disclosed recent recreational drug use including chemsex in the previous 3 months. RESULTS: In all, 2202/2501 (88%) patients were asked about recreational drug use and 514 (23%) disclosed recreational drug use. Eighty-two (4%) of these disclosed recent chemsex; 73 (89%) used crystal methamphetamine, 51 (62%) used gamma-hydroxybutyrate (GHB)/gamma-butyrolactone (GBL), 55 (67%) reported poly-drug use and 63 (76%) reported injecting drug use. The chemsex users were all cis-male MSM and were significantly older (53 vs. 46 years, p < 0.0001), and more likely to have had previous syphilis (73% vs. 28%, p < 0.0001) than patients reporting non-chemsex drug use. All chemsex users were prescribed antiretrovirals and 74 (90%) had an undetectable HIV viral load; 31 (38%) patients were taking either ritonavir (N = 12) or cobicistat (N = 19) as part of their antiretroviral regimen and this was similar to other patients attending for HIV care [31/82 (38%) vs. 768/2419 (31%), p = 0.25]. CONCLUSIONS: The prevalence of chemsex users among our HIV clinic attendants is 4%, and 38% of these were prescribed either ritonavir or cobicistat. Chemsex use should be a factor in antiretroviral therapy decision-making to avoid potential harm.

BACKGROUND: Alongside a recent revival in the use of psychedelics in clinical settings, there have been increases in the prevalence of recreational use, with many using psychedelics to deal with difficult emotions or to improve well-being. While clinical research is conducted in carefully controlled settings, this is not necessarily the case for recreational use. In this mixed methods online survey study, we aimed to develop an understanding of frequently used psychedelic harm reduction practices in recreational settings and how their use relates to the psychedelic experience. We also aimed to characterise users' first and most recent psychedelic trips to understand how harm reduction changes with experience. METHODS: Participants (n = 163) recounted their first and most recent psychedelic experience by providing details about the harm reduction practices they employed and completing the Challenging Experience Questionnaire (CEQ) and Emotional Breakthrough Inventory (EBI). We also asked open-ended questions for a more in-depth qualitative understanding of their views on psychedelic harm reduction. RESULTS: Using ANOVA, we observe greater use of harm reduction practices for participants' most recent versus first psychedelic experience and that use of these practices is positively associated with EBI scores and negatively associated with CEQ scores (particularly for the first experience). Participants engaged in a wide range of harm reduction practices and we provide details of those which are most commonly used and those which are deemed most important by experienced users. Our qualitative analysis indicated that participants were largely positive about psychedelics and many recounted profound positive experiences. While specifics of the drug they were taking was important for aspects of harm reduction, participants largely focused on the importance of ensuring a good "set and setting" for enhancing positive effects. CONCLUSIONS: Our research helps us understand how engagement in harm reduction may increase with experience. Our mixed methods data shed light on the perceived importance of different harm reduction practices and examine their association with the psychedelic experience itself. Together, our research has important implications for the development of psychedelic harm reduction advice and provides opportunities for future research to explore the importance of these different practices in more detail.

BACKGROUND/PURPOSE: Limited data are available on the role of illicit non-injecting drug use in a prolonged HIV outbreak that predominantly affected men who have sex with men (MSM) in Taiwan since 2006. We aimed to assess associations between specific types of drug use and incident HIV infections in this outbreak. METHODS: We conducted a retrospective case-control study among MSM clients at voluntary counselling and testing (VCT) service at National Taiwan University Hospital (Taipei, Taiwan). We used BED IgG-capture enzyme immunoassay to identify incident HIV infection (cases), individually matched to HIV-negative MSM clients (controls) by HIV testing date. We used a structured questionnaire to obtain the information on illicit drug use and sexual risk behaviors. RESULTS: From a total of 15,305 MSM client visits during 2006-2015, 387 cases were matched to 1012 controls. Use of inhaled nitrites (adjusted odds ratio [aOR] 2.1), MDMA (aOR 2.9), amphetamines (aOR 1.6), and ketamine (aOR 1.5) were independently associated with incident HIV infection. Polydrug (≥2 drugs) use was associated with the highest risk (aOR 4.3; 95% CI 2.6-7.2). While the proportion of MSM VCT clients who reported use of any recreational drug remained stable during 2006-2015 (average: 9.7%, P: 0.38), there was a shift in specific types of drug use, from MDMA/ketamine to inhaled nitrites/amphetamine, after 2011 (all Ps < 0.05). CONCLUSION: Non-opioid recreational drugs use is associated with incident HIV infection in this prolonged HIV outbreak. There is an urgent need to formulate an effective public health response to mitigate the risk.

INTRODUCTION: Chemsex in a European context is the use of any of the following drugs to facilitate sex: crystal methamphetamine, mephedrone and gamma-hydroxybutyrate (GHB)/gamma-butyrolactone (GBL) and, to a lesser extent, cocaine and ketamine. This study describes the prevalence of self-reported recreational drug use and chemsex in HIV-positive men who have sex with men (MSM) accessing HIV services in four countries. It also examines the problematic impacts and harms of chemsex and access to chemsex-related services. METHODS: This is a cross-sectional multi-centre questionnaire study of HIV-positive MSM accessing nine HIV services in the UK, Spain, Greece and Italy. RESULTS: In all, 1589 HIV-positive MSM attending HIV services in four countries completed the questionnaire. The median age of participants was 38 years (interquartile range: 32-46 years) and 1525 (96.0%) were taking antiretroviral therapy (ART). In the previous 12 months, 709 (44.6%) had used recreational drugs, 382 (24.0%) reported chemsex and 104 (6.5%) reported injection of chemsex-associated drugs ('slamsex'). Of the 382 engaging in chemsex, 155 (40.6%) reported unwanted side effects as a result of chemsex and 81 (21.2%) as a result of withdrawal from chemsex. The reported negative impacts from chemsex were on work (25.1%, 96), friends/family (24.3%, 93) and relationships (28.3%, 108). Fifty-seven (14.9%) accessed chemsex-related services in the past year, 38 of whom (67%) felt the service met their needs. DISCUSSION: A quarter of participants self-reported chemsex in the past 12 months. There were high rates of harms from chemsex across all countries, including negative impacts on work, friends/family and relationships. Although a minority of those engaging in chemsex accessed support, most found this useful.

BACKGROUND: Silexan is a lavender essential oil with established anxiolytic and calming efficacy. Here we asked whether there is a potential for abuse in human patients. METHODS: We carried out a phase I abuse liability single-center, double-blind, 5-way crossover study in healthy users of recreational central nervous system depressants. They received single oral doses of 80 mg (therapeutic dose) and 640 mg Silexan, 2 mg and 4 mg lorazepam (active control) and placebo in randomized order, with 4- to 14-day washout periods between treatments. Pharmacodynamic measures included validated visual analogue scales assessing positive, negative, and sedative drug effects and balance of effects; a short form of the Addiction Research Center Inventory; and a drug similarity assessment. The primary outcome measure was the individual maximum value on the drug liking visual analogue scale during 24 hours post-dose. RESULTS: Forty participants were randomized and 34 were evaluable for pharmacodynamic outcomes. In intraindividual head-to-head comparisons of the drug liking visual analogue scale maximum value, both doses of Silexan were rated similar to placebo whereas differences were observed between Silexan and lorazepam and between placebo and lorazepam (P < .001). These data were supported by all secondary measures of positive drug effects and of balance of effects. Differences between placebo and both doses of Silexan were always negligible in magnitude. Moreover, Silexan showed no sedative effects and was not perceived to be similar to commonly used drugs that participants had used in the past. CONCLUSIONS: Silexan did not exhibit any abuse potential in a standard abuse potential detection screen study and is unlikely to be recreationally abused.

We analysed the impact of recreational drug use (RDU) on different outcomes in people living with HIV (PLHIV). A multicentre retrospective cohort study was performed with two cohorts of PLHIV included: people using recreational drugs (PURD) vs. people not using recreational drugs (PNURD). Overall, 275 PLHIV were included. RDU was associated with men having sex with men (OR 4.14, 95% CI [1.14, 5.19]), previous sexually transmitted infections (OR 4.00, 95% CI [1.97, 8.13]), and current smoking (OR 2.74, 95% CI [1.44, 5.19]). While the CD4/CD8 ratio increased amongst PNURD during the follow-up year, it decreased amongst PURD (p = 0.050). PURD presented lower scores of self-reported and multi-interval antiretroviral adherence (p = 0.017, and p = 0.006, respectively), emotional well-being (p < 0.0001), and regular follow-up (p = 0.059), but paid more visits to the emergency unit (p = 0.046). RDU worsens clinical, immunological, and mental health outcomes amongst PLHIV.
RESUMEN: Analizamos el impacto del consumo de drogas recreativas sobre variables relacionadas con la salud en personas con VIH (PVIH). Estudio multicéntrico retrospectivo con dos cohortes de PVIH: consumidores de drogas recreativas (CDR) y no consumidores (NCDR). Se incluyeron 275 PVIH. El consumo de drogas recreativas se asoció al colectivo de hombres que mantienen sexo con hombres (OR 4.14, IC95% [1.14, 5.19]), a infecciones de transmisión sexual previas (OR = 4.00, IC95% [1.97, 8.13]) y a ser fumador (OR = 2.74, IC95% [1.44, 5.19]). El ratio CD4/CD8 aumentó entre los NCDR durante el año de seguimiento y disminuyó en los CDR (p = 0.050). Los CDR presentaron peor adherencia al tratamiento antiretroviral medida con dos métodos indirectos (p = 0.017 y p = 0.006, respectivamente), y bienestar emocional (p < 0.0001). Además, visitaron menos al especialista en enfermedades infecciosas (p = 0.059), y más a urgencias (p = 0.046). El consumo de drogas recreativas empeora los resultados clínicos y de salud mental entre las PVIH.

BACKGROUND: Recreational and sexual drug use among men who have sex with men may result in increased risk of poor health. The aim of this study was to better understand drug use and harm reduction techniques among Swedish men who have sex with men traveling to Berlin in order to improve the health of this population and inform public health strategies. METHODS: A qualitative study based on semi-structured interviews with 15 Swedish men aged 23-44 with experience of drug use were recruited through network sampling. Interviews were conducted in Stockholm and Berlin and analysed using content analysis. The interview guide included questions on drug use, context, health and safety. RESULTS: The participants engaged in drug use in both settings and in various contexts. Participants saw themselves as capable of finding a balance between pleasure, safety and risk with the aim to maximize positive effects while minimizing negative ones. The different risks of drug use were known, and participants relied on knowledge, harm reduction strategies and self-defined rules of intake to stay safe and healthy in a broad sense, both short term (i.e. during each session) and long term. Choice of drug and, frequency of intake, multi-use, risk of overdose, risk of HIV, purpose and context of use, how often, etc. were all part of the overall strategy. Knowledge of these methods was spread within the community and on-line rather than from counsellors or other health care providers. However, it did not always translate perfectly into practice and some had experienced overdoses and problematic use. CONCLUSIONS: The findings of this study point to the need for increased adoption of harm reduction techniques in this population focusing on mitigating harm and prevention of risk of problematic use or starting injection drugs. Existing traditional services require adaptations to become more accessible and acceptable to sub-groups of drug users, including low-threshold services providing non-judgemental, evidence-based information. This will require funding of alternative providers such as STI/HIV clinics, among others, and health care providers to increase adoption of prevention strategies, specifically pre-exposure prophylaxis for HIV.

BACKGROUND: There is limited information about the types of recreational drugs used by men who have sex with men (MSM) in China or the consequent impact on sexual health and human immunodeficiency virus (HIV) acquisition. METHODS: We recruited MSM from seven cities in China between 2012 and 2013 using multiple approaches including advertisements on gay websites, collaborating with local MSM community-based organizations, peer referrals, and venues such as gay bars and bathrooms visited by MSM. We divided participants into four subgroups based on the number of recreational drugs (RDs) used in the previous 6 months. We defined use of multiple RDs as use of ≥2 types of RDs. Demographics and HIV-related high-risk behaviors were collected, and blood samples were tested for recent HIV infection by the HIV-1 subtypes B, E, and D immunoglobulin G capture enzyme immunoassay (BED-CEIA). We used multivariable logistic regression adjusted for sociodemographics to determine the adjusted odds ratios (aORs) and associated 95% confidence intervals (CIs) of the subgroups of RD use for recent or established HIV infection. RESULTS: A total of 4496 Chinese MSM participated; 28.4% used RDs, and 5% used multiple types of RDs. The prevalence of each RD use was as follows: poppers (25.9%), ecstasy (2.4%), ketamine (1.2%), amphetamine (0.6%), tramadol (0.4%), methamphetamine (3.8%), and codeine (1.9%). Users of multiple RDs commonly used poppers combined with one or more other types of RDs. Multiple RD users were likely to be aged 26-30 years (vs. 18-25 and > 30 years), live in non-local cities (vs. local cities), never married (vs. married), have a high monthly income (vs. no income and 1-599 USD), use versatile positions during anal intercourse (vs. top or bottom), and have inadequate HIV-related prevention knowledge (vs. adequate). As the number of RDs used in the previous 6 months increased, the prevalence of HIV-related high-risk behaviors increased (P < 0.05 for all). The odds of recent HIV infection were higher among those who used one type (aOR = 2.2, 95% CI: 1.5-3.0) or two types of RD (aOR=2.3, 95% CI: 1.0-5.2) in the previous 6 months compared to the odds among those who did not use RDs. CONCLUSION: The level and pattern of multiple RD use among Chinese MSM were different from high-income countries. MSM who used more RDs are more likely to engage in high-risk sexual behaviors, and these behaviors may be associated with increases in new HIV infections.

OBJECTIVES: Chemsex refers to the use of sex-enhancing drugs among men who have sex with men (MSM) in combination with specific sexual and social behaviours. Longitudinal data on this development and the associated health risks are scarce. METHODS: Data on all recreational drugs reported in the Swiss HIV Cohort Study (SHCS) from 2007 to 2017 were collected. Drug use was analysed longitudinally for all drug classes. In addition, potential associations between patient characteristics and the consumption of methamphetamine, γ-hydroxybutric acid/γ-butyrolactone (GHB/GBL), 3,4-methylenedioxymethamphetamine (MDMA/XTC), cocaine and amphetamine were analysed. RESULTS: We analysed 166 167 follow-up entries for 12 527 SHCS participants, including 7101 free text field entries containing information about recreational drugs other than cannabis, cocaine and heroin. Overall, we observed a stable percentage (9.0%) of recreational drug use (excluding cannabis, amyl nitrite and prescription drugs). For MSM, however, there was an increase in overall drug use from 8.8% in 2007 to 13.8% in 2017, with particularly large increases for methamphetamine (from 0.2 to 2.4%; P < 0.001) and GHB/GBL (from 1.0 to 3.4%; P < 0.001). The use of each of the potentially sex-enhancing drugs methamphetamine, GHB/GBL, cocaine, XTC/MDMA and amphetamine was significantly associated with condomless sex with nonsteady partners, and higher prevalences of depression, syphilis and hepatitis C. CONCLUSIONS: The significant increase in the use of chemsex drugs among MSM in the SHCS and the strong association with coinfections and depression highlights the need for harm reduction programmes tailored to MSM. According to our results, improving knowledge about recreational drugs is important for all health care professionals working with people living with HIV.

The present study aimed to explore how food or substance consumption (e.g., experiencing hunger, or having consumed alcohol or recreational drugs) could shape consumer impulsive spending on sports betting products. Based on a large online sample of Australian sports bettors, we found that participants with higher hunger level, or having consumed more alcohol or recreational drugs, tended to have increased impulsive bet size. These impulsiveness effects had both direct and indirect effect components. The significant direct effects confirmed that positive relationships directly existed between hunger, alcohol consumption, or recreational drug consumption and impulsive bet size, even when all potential mediators and covariates were statistically controlled. Moreover, results regarding specific indirect effects demonstrated that hunger, alcohol consumption, or recreational drug consumption was also indirectly linked with impulsive bet size, via their relationships with both promotional and financial influences, rather than social influences. Furthermore, participants' Problem Gambling Severity Index score was positively associated with their impulsive bet size. These findings support and complement the literature on impulsivity as well as the research on strategies for staying in control of gambling, and have implications for consumers, regulators, and treatment/help providers.

AIMS: Illegal substance use at music festivals is less documented than it is in nightlife and electronic dance music settings. This study investigated such use through questionnaires, breathalysers and oral fluid drug testing. We also examined the associations between testing positive for illegal substances and demographics, self-reported substance use and measured blood alcohol concentration levels. METHODS: A cross-sectional study of 1,309 festival attendees from six Norwegian music festivals taking place between July and August 2016. Logistic regression models estimated the likelihood of a positive oral fluid drug test. Covariates were male, age, education, employment, smoking status, early age for alcohol intoxication, alcohol intoxication ⩾2 times a week, past-month and past-year illegal substance use, blood alcohol concentration levels and festivals. RESULTS: Overall, 12% reported illegal substance use in the past 30 days and 11% tested positive for illegal substances. Cannabis (6%), cocaine (3%) and MDMA/ecstasy (2%) were most commonly detected. One-third had a blood alcohol concentration ⩾0.10%. Of those with a positive test result ( n=146), 95% had detectable alcohol levels and 41% had a blood alcohol concentration above 0.10%. Those studying or working part-time were less likely to test positive compared to those who were not employed. Furthermore, those reporting daily smoking and past-year cannabis or MDMA/ecstasy use were more likely to test positive, compared to those not reporting such use. CONCLUSIONS: Illegal substance use was less prevalent than in previous nightlife and electronic dance music studies. Almost all those testing positive for illegal substances had detectable alcohol levels and 41% had a blood alcohol concentration greater than 0.10%, possibly indicating combined use.

BACKGROUND: HIV-infected men who have sex with men (MSM) who use recreational drugs (RD) or excessive alcohol (EA) may be involved in risky sexual behaviours, including unprotected anal intercourse (UAI). This study describes the prevalence RD/EA-use among HIV-infected MSM, and compares those who used RD/EA with those who did not. METHODS: This cross-sectional study included HIV-infected MSM who were recruited in a convenient sample from two AIDS-treatment centres and events for HIV-infected MSM in Israel in 2016. Participants completed anonymous questionnaires including RD/EA-use and their sexual behaviours. RD/EA-use was defined as consumption of any psychoactive stimulants or dissociative anaesthetics, or an uptake of alcohol until drunkenness before or during sex. RESULTS: Of all 276 HIV-infected MSM, 202 (73.2%) used RD/EA. Those who used RD/EA were younger, reported earlier sexual debut, had more sexual partners, were more likely to perform UAI with casual partners, more commonly involved in paid sex, used psychiatric medications and more likely to be unsatisfied with their health-status compared to those who did not use RD/EA. HIV-infected MSM who used RD/EA reported a lower CD4-count and higher viral-load than those who did not. In a multivariate analysis, being younger, reported earlier sexual debut and been prescribed psychiatric drugs were associated with RD/EA-use among HIV-infected MSM. CONCLUSIONS: A large proportion of HIV-infected MSM used RD/EA and also engaged in risky sexual behaviours. A subset of HIV-infected MSM can benefit from mental support during their routine treatment at the AIDS treatment centres and should also receive harm reduction intervention by their providers in order to minimize potential risks pertaining to RD/EA-use.

Background: Self-reported data are commonly used when investigating illicit substance use. However, self-reports have well-known limitations such as limited recall and socially desirable responding. Mislabeling or adulteration of drugs on the illicit market may also cause incorrect reporting. Objectives: We aimed to examine what could be gained in terms of illicit drug use findings among music festival attendees when including biological sample test results in the assessment. Methods: We included 651 attendees at three music festivals in Norway from June to August 2016. Self-reported drug use was recorded using questionnaires, and samples of oral fluid were analyzed to detect use of illicit drugs. In addition, we analyzed samples of pooled urine from portable toilets at each festival. Results: All methods identified cannabis, MDMA, and cocaine as the most commonly used drugs. Overall, 6.6% of respondents reported use of illicit substances during the previous 48 hours. Oral fluid testing identified a larger number of drug users as 12.6% tested positive for illicit drugs. In oral fluid testing, we identified ketamine and three new psychoactive substances (NPS) that had not been reported on the questionnaire. In pooled urine testing, we identified amphetamine and three additional NPS that were neither reported used nor found in oral fluid samples. Conclusions/Importance: Drug testing of biological samples proved to be an important supplement to self-reports as a larger number of illicit substances could be detected.

Although recreational drug use is associated with risky sexual behaviors and HIV infection among men who have sex with men (MSM), it is unclear to what extent these behaviors and outcomes differ between single-drug users and polydrug users in China. This is a cross-sectional study conducted from July to September 2016 among MSM in three cities of Sichuan Province, China. Multinomial logistic regression was performed to examine factors correlated with single-drug and polydrug use. A total of 1,122 participants were included in the study. Overall, 28% of MSM have ever used recreational drugs, of whom 64.0% were single-drug users, and 36.0% were polydrug users. Factors associated with both single-drug and polydrug use included: receptive sexual role (single-drug use: AOR = 1.79, 95% CI: 1.05-3.07; polydrug use: AOR = 6.00, 95% CI: 2.54-14.17), engaging in group sex (AOR = 2.23, 95% CI: 1.28-3.87; AOR = 4.68, 95% CI: 2.41-9.08), frequent alcohol use (AOR = 3.11, 95% CI: 1.75-5.52; AOR = 6.41, 95% CI: 2.50-16.47), seeking partners mainly by Internet (AOR = 4.87, 95% CI: 3.31-7.17; AOR = 4.58, 95% CI: 2.58-8.14), history of STIs (AOR = 1.86, 95% CI: 1.08-3.21; AOR = 3.32, 95% CI: 1.77-6.26) and HIV infection (AOR = 1.76, 95% CI: 1.02-3.02; AOR = 3.19, 95% CI: 1.62-6.26). Our findings suggest the urgent need for HIV and STIs prevention programs among MSM in China to integrate strategies that mitigate recreational drug use.

BACKGROUND: Recreational use of prescription drugs is widespread. We describe acute poisonings related to the recreational use of prescription drugs. METHODS: Retrospective observational study. We retrospectively registered all patients presenting from October 2013 through March 2015 at a primary care emergency outpatient clinic in Oslo, Norway, with an acute poisoning related to recreational drug use. We registered demographic data, toxic agents taken, clinical course and treatment. From this data set we extracted the 819/2218 (36.9%) cases involving one or more prescription drugs. RESULTS: Among the 819 included cases, 190 (23.2%) were female. Median age was 37 years. The drugs most commonly involved were benzodiazepines in 696 (85.0%) cases, methadone in 60 (7.3%), buprenorphine in 53 (6.5%), other opioids in 56 (6.8%), zopiclone/zolpidem in 26 (3.2%), and methylphenidate in 11 (1.3%). Prescription drugs were combined with other toxic agents in 659 (80.5%) cases; heroin in 351 (42.9%), ethanol in 232 (28.3%), amphetamine in 141 (17.2%), cannabis in 70 (8.5%), gamma-hydroxybutyrate (GHB) in 34 (4.2%), cocaine in 29 (3.5%), and other illegal drugs in 46 (5.6%). The patient was given naloxone in 133 (16.2%) cases, sedation in 15 (1.8%), and flumazenil in 3 (0.4%). In 157 (19.2%) cases, the patient was sent on to hospital. CONCLUSIONS: One in three acute poisonings related to recreational drug use involved prescription drugs. Benzodiazepines were by far the most common class of drugs. Prescription drugs had mostly been taken in combination with illegal drugs or ethanol.

Marijuana is the most commonly used recreational drug in the United States, and legal recreational and medicinal use has gained public acceptance during the last decade. Twenty-nine US states have established medical marijuana programs, 8 of which have also legalized recreational marijuana, and Canada is expected to legalize recreational marijuana in 2018. Advanced chronic kidney disease (CKD) and end-stage renal disease (ESRD) are chronic conditions with significant associated morbidity and mortality. Patients experience substantial symptom burden that is frequently undertreated due to adverse medication side effects. This article reviews the available evidence for the use of medical marijuana to manage chronic pain, nausea/vomiting, anorexia/cachexia, and pruritus, all of which are frequently reported by patients with advanced CKD or ESRD. Potential adverse health effects of medical and recreational marijuana use are also discussed. Regardless of personal, social, and political beliefs, marijuana use is becoming mainstream, and nephrologists should be aware of the potential impact on our patient population. Further research is warranted to investigate the renal endocannabinoid system, the impact of marijuana use on kidney disease outcomes, and the risks and benefits of medical marijuana use on symptoms of advanced CKD and ESRD.
