RESUMO
AIMS: Although recreational drug use may induce ST-elevated myocardial infarction (STEMI), its prevalence in patients hospitalized in intensive cardiac care units (ICCUs), as well as its short-term cardiovascular consequences, remains unknown. We aimed to assess the in-hospital prognosis of STEMI in patients with recreational drug use from the ADDICT-ICCU study. METHODS AND RESULTS: From 7-22 April 2021, recreational drug use was detected prospectively by a systematic urine multidrug test in all consecutive patients admitted for STEMI in 39 ICCUs across France. The primary endpoint was major adverse cardiac events (MACEs) defined by death, resuscitated cardiac arrest, or cardiogenic shock. Among the 325 patients (age 62 ± 13 years, 79% men), 41 (12.6%) had a positive multidrug test (cannabis: 11.1%, opioids: 4.6%, cocaine: 1.2%, 3,4-methylenedioxymethamphetamine: 0.6%). The prevalence increased to 34.0% in patients under 50 years of age. Recreational drug users were more frequently men (93% vs. 77%, p = 0.02), younger (50 ± 12 years vs. 63 ± 13 years, P < 0.001), and more active smokers (78% vs. 34%, P < 0.001). During hospitalization, 17 MACEs occurred (5.2%), including 6 deaths (1.8%), 10 cardiogenic shocks (3.1%), and 7 resuscitated cardiac arrests (2.2%). Major adverse cardiac events (17.1% vs. 3.5%, P < 0.001) and ventricular arrhythmia (9.8% vs. 1.4%, P = 0.01) were more frequent in recreational drug users. Use of recreational drugs was associated with more MACEs after adjustment for comorbidities (odds ratio = 13.1; 95% confidence interval: 3.4-54.6). CONCLUSION: In patients with STEMI, recreational drug use is prevalent, especially in patients under 50 years of age, and is independently associated with an increase of MACEs with more ventricular arrhythmia.

RESUMO
INTRODUCTION: Prevalence and patterns of alcohol and other drug (AOD) use among specific lesbian, gay, bisexual, transgender (trans) and queer (LGBTQ+) subpopulations are well established. However, patterns of substance-related risk have been less thoroughly explored. This study aimed to determine typologies AOD risk among LGBTQ+ adults in Australia. METHOD: Latent class analyses were performed to determine distinct patterns of AOD risk (n = 6835), as measured by the Alcohol Use Disorder Identification Test and Drug Abuse Screening Tool. Demographic characteristics, experience of harassment, assault and/or threats, mental wellbeing and LGBTQ+ connectedness were compared across emergent classes. RESULTS: AOD risk was characterised as 'no risk' (13.3% of sample), 'low risk' (15.1%), 'moderate risk' (alcohol + other drugs; 30.1%), or 'moderate alcohol only risk' (41.5%). The 'moderate risk' class was the most likely class to report recent sexual assault, verbal abuse, harassment and physical threats compared to other classes, while those in the 'moderate alcohol only risk' group were least likely to report these experiences of all classes. However, both the 'moderate risk' and 'moderate alcohol risk only' classes reported greater mental wellbeing and LGBTQ+ connectedness compared to the 'no risk' and 'low risk' classes. DISCUSSION AND CONCLUSIONS: Our findings indicate that level of AOD risk is not uniform among some LGBTQ+ adults, nor is the distribution of harms experienced by them. Tailored harm-reduction interventions may be fruitful in attenuating harms based on risk profile; most specifically, LGBTQ+ individuals engaging in moderately risky concurrent AOD use.

RESUMO Este artigo trata das adolescências, no plural, como construção histórico-social de um processo dinâmico, e do adolescente perante seus modos de vida e expressão em um contexto histórico-social e singular. Entende-se aqui que ações meramente prescritivas são insuficientes para responder às complexidades dos processos de adoecimento mental na sociedade contemporânea. Objetivou-se compreender o contexto das práticas de cuidado em saúde ao adolescente em vulnerabilidade, diante do uso de drogas, na dimensão das tensões dos campos de práticas do cuidado em saúde. Estudo descritivo exploratório de abordagem qualitativa, que realizou entrevistas com profissionais da área da saúde (Unidade Básica de Saúde e Centro de Atenção Psicossocial Infantojuvenil). Destacam-se as tensões no campo de práticas entre o modelo assistencial biomédico e de guerra às drogas versus o psicossocial/comunitário; redução de estigma; acesso; redução de danos e nos atendimentos individuais, bem como a importância de refletir e fomentar o processo de mudança da mentalidade diante do adoecimento mental, visando atualizar as formas de cuidar. Esse processo tem sido realizado conforme os princípios da Reforma Psiquiátrica Brasileira, com avanços e retrocessos que repercutem na atualização das práticas de cuidado em saúde mais alinhadas às propostas de ações psicossociais e redutoras de vulnerabilidade.
ABSTRACT This article deals with adolescences, in the plural, as a socio-historical construction of a dynamic process and with the experience of adolescents with their lifestyle and self-expression in a unique socio-historical context. It assumes that purely prescriptive measures are insufficient to address the complexity of mental illness processes in contemporary society. This study aims to understand the context of health care practices for vulnerable youth, particularly those involved in substance use, through the lens of tensions in health practice domains. This is an exploratory, descriptive study using a qualitative approach, with interviews conducted with health professionals (in Basic Health Unit and Psychosocial Care Center for Children and Adolescents). The study highlights the tensions within health practice between the biomedical model and the war on drugs and a community-based psychosocial approach; it underlines the need for reducing stigmatization, improving access, harm reduction, and individualized care. It also emphasizes the importance of considering and promoting a shift in mentality towards mental illness in order to develop care strategies. This process was carried out in line with the principles of the Brazilian Mental Health Reform, with advances and setbacks that affect the updating of health practices, which are more oriented towards proposals for psychosocial and vulnerability-reducing actions.
RESUMO
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.

This study aimed to characterize patients admitted to critical care following Emergency Department (ED) presentation with acute recreational drug toxicity and to identify determinants of admission to critical care. A retrospective multicenter matched case-control study was conducted by the European Drug Emergency Network Plus (Euro-DEN Plus) over the period 2014-2021. The cases were ED presentations with acute recreational drug toxicity admitted to critical care, the controls consisted of ED presentations with acute recreational drug toxicity medically discharged directly from the ED. The potential determinants of admission to critical care were assessed through multivariable conditional stepwise logistic regression analysis and multiple imputation was used to account for the missing data. From 2014 to 2021, 3448 Euro-DEN Plus presentations involved patients admitted to critical care (76.9% males; mean age 33.2 years; SD 10.9 years). Patient age ≥35 years (as compared to ≤18 years) was a determinant of admission to critical care following acute recreational drug toxicity (adjusted odds ratio, aOR, 1.51, 95% confidence interval, CI, 1.15-1.99), along with polydrug use (aOR 1.39, 95% CI 1.22-1.59), ethanol co-ingestion (aOR 1.44, 95% CI 1.26-1.64), and the use of gamma-hydroxybutyrate/gamma-butyrolactone (GHB/GBL, aOR 3.08, 95% CI 2.66-3.57). Conversely, lower odds of admission to critical care were associated with the use of cocaine (aOR 0.85, 95% CI 0.74-0.99), cannabis (aOR 0.44, 95% CI 0.37-0.52), heroin (aOR 0.80, 95% CI 0.69-0.93), and amphetamine (aOR 0.65, 95% CI 0.54-0.78), as was the arrival to the ED during the night (8 p.m.-8 a.m., aOR 0.88, 95% CI 0.79-0.98). These findings, which deserve confirmation and further investigation, could contribute to a more complete understanding of the decision-making process underlying the admission to critical care of patients with acute recreational drug toxicity.
RESUMO
(1) Background: To evaluate the epidemiological profile of people who use drugs at the PrEP outpatient clinic of the University Hospital of Brasília; (2) Methods: Cross-sectional study with a review of data from medical records referring to the first medical consultation. The prevalence ratio was calculated using a Poisson regression model with robust variance; (3) Results: A total of 53% of subjects reported drug use in the last 3 months. The unadjusted prevalence ratio of drug use in trans women was PR: 9.0 (95%CI: 1.4-57.5). people who use drugs have a 1.9 times higher prevalence of STI diagnosis, and a 2.4 times higher prevalence of partners compared to non-users; (4) Conclusions: Substance use was associated with a higher STI prevalence ratio and number of sexual partners.
RESUMO
INTRODUCTION: This study investigates differences in health and well-being associated with current, past or no injecting drug use (IDU) among people living with HIV (PLHIV) in Australia, identifying key health care considerations between injecting experiences. METHODS: Data were extracted from the HIV Futures 9 study; a survey of PLHIV conducted in 2018-2019. Chi-square and analysis of variance analyses compared clinical and treatment characteristics, major physical and mental comorbidities, sexually transmitted infection diagnoses, and quality of life for those who reported current (last 12 months), past (12+ months ago) or no IDU. RESULTS: Current IDU (n = 106) was associated with higher rates of sexually transmitted infection testing and diagnoses, higher frequency of self-reported antiretroviral therapy non-adherence due to drug use and greater social quality of life than past (n = 126) or no IDU (n = 508; total N = 740). Past and current IDUs were associated with more mental illness diagnoses and self-reported concern about drug use. Past IDU was associated with more physical comorbidities, lower satisfaction with clinical care and greater difficulty in affording health care than current or no IDU. DISCUSSION AND CONCLUSIONS: Past and current IDUs are associated with unique health concerns. However, past IDU appears to be related to greater dissatisfaction in navigating health care than individuals with current IDU experience. Higher social connection and the types of services being accessed by individuals who currently inject may play a role in shaping service satisfaction. Peer-based interventions to help support individuals in accessing services that are affirming of their needs is an ongoing priority.

BACKGROUND AND HYPOTHESIS: Distress associated with auditory (AH) and visual (VH) hallucinations in the general population was found to be predictive of later need for mental healthcare. It is, therefore, important to understand factors relating to the distress individuals experience from their hallucinations. Hallucinations can easily occur under substance-induced states, but recreational drug use is also known as a self-medication strategy. The current study, therefore, investigated whether recreational drug use by individuals from the general population is associated with the degree of distress experienced from AH and/or VH. STUDY DESIGN: Drug use and distress severity associated with AH (N = 3.041) and/or VH (N = 2.218) were assessed by means of an online survey in the general Dutch population (>14 years of age). STUDY RESULTS: Multiple linear regression revealed that while past month consumption of alcohol was associated with less AH- and VH-related distress, past month cannabis use was associated with more AH- and VH-related distress. Furthermore, past month use of nitrous oxide was associated with more severe VH-related distress. CONCLUSION: Recreational use of alcohol, cannabis, and nitrous oxide may play important differential roles in the degree of distress associated with AH and VH in individuals from the general population. The consumption of these substances could form a potential risk factor for the development of distressing hallucinations or function as a signal marker for their occurrence. Due to the cross-sectional design of the current study, the causal relation between recreational drug use and distressing hallucinations remains to be elucidated.

Growing research exploring the utility of psychedelic substances suggests that they not only hold promise for clinical practice but may enhance mental health through recreational use as well. However, given the importance of set and setting for maximizing benefits and minimizing harms of drug use, it is important to develop a foundational understanding of the contextual factors associated with positive and negative mental health in psychedelic users. Accordingly, data were collected using an internet-based survey of psychedelic drug users (n = 511). Hierarchical regression analyses were used to explore to what degree life-time use, frequency of use, dose size, group use, intentions for use, and post-use integration predict mental health in psychedelic users. In particular, using psychedelics with high frequency and to cope with negative affect were found to predict negative mental health. Conversely, using psychedelics in a group setting, with self-expansive intentions, and integrating post-use were found to predict positive mental health. Findings suggest that recreational psychedelic use may either enhance or diminish mental health depending on the contextual parameters of use. Limitations and areas for further research are discussed.

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.

To shed more light on the addictive power of the gabapentinoids (GPTs) gabapentin and pregabalin, we performed a structured face-to-face interview with GPT-users about DSM-IV-dependence-criteria (sedatives), consume-motives and cessation-needs. Among 100 patients consecutively admitted to a detoxification-ward, fifteen (15%) reported lifetime GPT-use (18-50 years old, 2 females): seven (7%) used gabapentin, twelve (12%) pregabalin and four had lifetime experiences with both GPTs. Of the seven gabapentin-users, three patients were dependent including one person with a spontaneous remission. Of the 12 pregabalin-users, five were dependent, including two persons with a spontaneous remission. Fourteen of fifteen cases reported GPT-use side-by-side with an opioid-use, mostly for sparing opioids. Twelve GPT-users additionally co-used benzodiazepines. In no case, a GPT was the reason for detoxification treatment or reported to be involved in an emergency event. Altogether, every 7th patient (n = 15) of our inpatient detoxification-seeking sample reported GPT-use including 50% (n = 8) who were dependent. Among them, 35% (3/8) had been already spontaneously remitted. As GPT-users reported no cession-need and the vast majority were primarily affected by co-occurring opioid- and benzodiazepine-addiction, we assume that GPTs more likely played a bystander-role than mediating the addictive behavior of this population with multiple recreational drug use experience.

O presente estudo visa avaliar, através de uma revisão narrativa da literatura, como o controle do Estado exerceu ao longo da história do Brasil a regulamentação do uso de drogas. Método Foram consultados livros, artigos de periódicos acadêmicos indexados, trabalhos completos apresentados em congressos e documentos históricos disponíveis na internet relativos ao tema. Resultados A primeira legislação penal em relação ao uso de drogas surge apenas no Brasil império. Nesse período começam a surgir também os primeiros problemas devido ao uso de drogas. A criação de cursos superiores nas áreas de saúde e de ciências naturais veio a formar profissionais capacitados na manipulação e fiscalização de produtos químicos e farmacêuticos. Com o tempo, observando-se os efeitos, algumas substâncias passam a ser proscritas. Conclusão Por toda história do país, o uso e a regulação das drogas, permearam todas as épocas influenciando na cultura, educação e no modo de vida da população. Atualmente há um grande debate acerca das políticas sobre drogas no Brasil, principalmente sobre a maconha e seus usos terapêuticos, mostrando novamente a influência do Estado sobre a saúde e a segurança da população.
The present study aims to evaluate, through a narrative review of the literature, how State's control has exercised regulation of drug use throughout the history of Brazil. Method Books, articles from indexed academic journals, complete works presented at conferences and historical documents available on the internet relating to the topic were consulted. Results The first criminal legislation related to drug use only appeared in Imperial Brazil. During this period, the first problems due to drug use also begin to appear. The creation of higher education courses in the areas of health and natural sciences resulted in the training of professionals capable of handling and supervising chemical and pharmaceutical products. Over time, observing the effects, some substances become proscribed. Conclusion Throughout the country's history, the use and regulation of drugs has permeated all eras, influencing culture, education and the population's way of life. There is currently a great debate about drug policies in Brazil, mainly regarding marijuana and its therapeutic uses, once again showing the influence of the State on the health and safety of the population.

There is a paucity of research, especially in the UK, that investigates individual differences in both medical and recreational cannabis users. A cross-sectional survey study design was used to assess recreational cannabis users and medical cannabis users currently living in the UK. Recreational cannabis users were invited to take part via social media. Medical cannabis users were recruited from Sapphire Medical Clinics, London, UK, which provides treatment with prescribed cannabis-based medicinal products. Demographic data and cannabis use frequency, as well as post-traumatic stress disorder symptoms (PCL-5), depression symptoms (Centre for Epidemiological Studies Depression Scale), trait and state anxiety (State-Trait Anxiety Inventory), and cannabis use motives [Comprehensive Marijuana Motives Questionnaire (CMMQ)] were collected. The Chi-square and independent-sample t-tests were used for the comparison of categorical variables and normally distributed continuous variables. Data were analyzed using analyses of variance (ANOVAs) and t-tests. Statistical significance was considered where the value of p was <0.05. The survey was completed by 161 participants. Medical cannabis users were older, consumed cannabis more often, had a higher "Sleep" motive on the CMMQ, and had a higher prevalence in self-reporting current diagnoses of neurological problems, mood disorders, and anxiety disorders (p < 0.05). Recreational cannabis users had higher scores on several motives for use (e.g., "Enjoyment," "Coping," "Experimentation," "Boredom," and "Celebration") and higher state anxiety scores (p < 0.05). The most common motives for cannabis use in both groups were "Enjoyment," "Low Risk," and "Sleep." There were no differences between groups in gender, "Low-Risk" motive, post-traumatic stress disorder symptoms, depression scores, trait anxiety scores, self-reported prevalence of substance use-related disorders, and past consumption of alcohol, tobacco, or caffeine (p > 0.05). The current study not only demonstrates a difference in age and motivations for cannabis consumption between recreational and medical cannabis users but also shows areas of potential overlap, including mental health outcomes, past substance use, and gender. These UK-specific findings indicate that recreational cannabis users experience higher state anxiety, highlighting the need for further evaluation of potential anxiogenic/anxiolytic properties of cannabis. These findings demonstrate the importance of researching individual differences in cannabis users and hold significant implications for future research, clinical practice, and legislation.
RESUMO
Background: Cocaine use is a well-established risk factor for acute coronary syndrome (ACS) although other recreational drugs (RD), are increasingly considered as potential cardiac risk factors. Compared to ACS without RD use, worse outcomes have been described for RD-associated ACS. Objective: The aim of this study was to explore the use of RD in a contemporary cohort of young ACS patients. Methods: Between June 2016 and October 2019, ACS patients aged 18-50 years, admitted to OLVG Hospital in Amsterdam, were retrospectively analysed. Medical chart review was performed to obtain patient and clinical characteristics, RD use, cardiac risk factors, outcome and follow up. Results: A total of 229 patients were included in the study. Recreational drug use prior to ACS was present in 24.9% of all patients, with cannabis (16.2%), cocaine (4.8%), or both (2.6%) most commonly observed. RD users were predominantly young men (87.7%) and had a significantly higher tobacco use compared to non-RD users (89.5% vs. 62.8%, P < 0.001), also after adjusting for age and sex. RD use was associated with larger myocardial infarctions with significantly higher CK-MB levels (104 ± 116 U/L vs 62 ± 96, P = 0.040) and poorer left ventricular function measured by echocardiography as compared to non-users (P = 0.007). Conclusion: Recreational drug use was present in almost 25% of all young ACS patients evaluated for drug use and was associated with larger myocardial infarction resulting in poorer left ventricular function as compared to non-users. Additionally, RD-users were younger and were more often tobacco users, compared to non-users.
RESUMO
BACKGROUND: Recreational drug use has become more and more accepted in society. Availability and purity are rising and new psychoactive substances (NPS) are popping up.The aim of this study was to provide objective data on illicit drug use at a Belgian festival in order to report on arising trends. This may provide additional information to help develop preventive strategies. METHODS: A cross-sectional study took place during a music festival in the summer of 2019, where 43 samples of pooled urine were collected at four different locations and at different moments of the day. Analysis was performed using gas chromatography with a flame ionization detector (GC-FID) to determine ethanol concentrations. Drugs of abuse were quantified using liquid chromatography-tandem mass spectrometry. A qualitative analysis was performed using high-resolution mass spectrometry. RESULTS: Median ethanol concentration was 0.88g/L. Cocaine, 3,4-methylenedioxymethamphetamine (MDMA), amphetamines, ketamine, and cannabis were detected in almost every sample and often in high concentrations. Furthermore, two NPS were detected and a variety of over-the-counter medication and adulterants were also found. DISCUSSION: The findings were largely in-line with trends outlined in the European Drug Report. Striking were the relatively high concentrations of MDMA and ketamine and detection of two synthetic cathinones. Two possible adulterants of cocaine were detected, namely flecainide and amlodipine. CONCLUSION: Music festivals are considered a high-risk setting for alcohol consumption and illicit drug use. Analysis of pooled urine samples at a festival therefore provides a valuable method to evaluate trends and to screen for new substances. Wide-spread use of classical drugs and identification of two NPS were observed during a major international music festival in Belgium. Results need to be interpreted carefully, taking into account the possibilities and limitations of the used techniques and a standardized sampling is required.

Drug consumption estimates are of relevance because of public health effects as well as associated criminal activities. Wastewater analysis of drug residues enables the estimation of drug consumption and drug markets. Short-term and long-term trends of cocaine, MDMA (ecstasy), amphetamine (speed) and methamphetamine (crystal meth), were studied for the city of Amsterdam. MDMA (+41%) and cocaine (+26%) showed significantly higher weekend vs. week consumption, while no differences were observed for the other drugs. The consumption of MDMA, cocaine, amphetamine and methamphetamine significantly increased between 2011 and 2019. Weekly trends emerging from wastewater analyses were supported by qualitative and quantitative data from a recreational drug use monitoring scheme. However, information collected in panel interviews within nightlife networks and surveys among visitors of pubs, clubs and festivals only partially reflected the long term increase in consumption as registered from wastewater analysis. Furthermore, methamphetamine use was not well presented in survey data, panel studies and test service samples, but could be monitored trough wastewater analysis. This illustrates that wastewater analysis can function as an early warning if use and user groups are small or difficult to reach trough other forms of research. All in all, this study illustrates that wastewater-based epidemiology is complementary to research among user groups, and vice versa. These different types of information enable to connect observed trends in total drug consumption to behaviour of users and the social context in which the use takes place as well as validate qualitative signals about (increased) consumption of psychoactive substances. Such a multi angular approach to map the illicit drug situation on local or regional scale can provide valuable information for public health.

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.

Acute kidney injury (AKI) occurs infrequently in young patients and often raises concern for irreversible or deadly etiologies. However, AKI related to synthetic marijuana, colloquially known as K2, is an increasingly common phenomenon in the United States and resolves quickly with fluid resuscitation. Here, we present a case of a young male who presented with severe AKI that initially raised concern for the need to start renal replacement therapy. Laboratory testing revealed an elevated osmolar gap and negative urine drug screen, while urinalysis demonstrated acanthocytes, raising concern for toxic alcohol ingestion or vasculitis.
