Hard Boiled: Alcohol Use as a Risk Factor for MDMA-Induced Hyperthermia: a Systematic Review

A thematic analysis of MDMA-related harm and harm reduction experiences and knowledge in Aotearoa New Zealand

BACKGROUND

Methylenedioxymethamphetamine (MDMA) is a popular drug worldwide and use is prevalent in Aotearoa New Zealand. Although associated with some significant harms, including fatalities, MDMA is ultimately less harmful than other commonly consumed drugs. We aimed to expand the understanding of MDMA harm and harm reduction strategies from a consumer perspective so that national harm reduction efforts can be better informed.

METHODS

We conducted 14 semi-structured focus group discussions including 60 people (aged 18-67, median = 21) who use MDMA in the Southern region of Aotearoa New Zealand to explore their thoughts and experiences regarding MDMA associated harm and harm reduction. Reflexive thematic analysis was conducted from a critical realist perspective.

RESULTS

Five themes were generated; (1) Mindset and setting matters; (2) Looking after your body and mind, not overdoing it; (3) Other substances increase risk and harm; (4) Trusted friends and peers are protective; and (5) Valid information is key for healthy self-determination; and one subtheme 5.1) Drug checking is essential harm reduction.

CONCLUSIONS

We discuss the implications for MDMA consumers and aim to inform national drug policy and the harm reduction practices of consumers and organisations, for the ultimate purpose of reducing MDMA-related harm in Aotearoa New Zealand.

Harm reduction behaviours and harm experiences of people who use 3,4-methylenedioxymethamphetamine (MDMA) in Aotearoa New Zealand

BACKGROUND

3,4-Methylenedioxymethamphetamine (MDMA) is drug of high prevalence in Aotearoa New Zealand and is the primary drug analysed by legal drug checking services. We aimed to address the gap in literature pertaining to MDMA-related harm reduction behaviour and harm experiences within the country.

METHODS

An online survey was used to assess the harm reduction behaviours (e.g., limiting consumption, planning use, seeking information) of people who use MDMA, in addition to their use of reagent testing and the major national drug checking and harm reduction service, KnowYourStuffNZ.

RESULTS

In total, 915 people completed the survey (60.7% females, aged 18-65, median = 24, IQR = 20-28). Frequency of various MDMA-related harm reduction behaviours differed, although these were carried out relatively frequently by most participants. Those who reported experiencing harm (physical, psychological, spiritual, social) from MDMA, or another drug presumed to be MDMA, reported less frequent harm reduction behaviours than non-harmed consumers. Reagent testing of MDMA had been conducted by 42.3% of the sample. Approximately 27% of the sample had used KnowYourStuffNZ services. Of KnowYourStuffNZ clients, 95.9% reported learning about harm reduction, and 53.3% reported changing their behaviour because of the service. Reasons for not using the KnowYourStuffNZ service were primarily lack of availability in local area (32.8%) or at relevant events (51.8%), and lack of concern with substance quality (29.8%). MDMA harm was reported by 14.4% of the sample, whilst reported harm was more common from consumption of presumably non-MDMA substances, self-reported as being mistaken for MDMA. Harm was primarily physical or psychological. Potential MDMA dependence was apparent in 6.9% of the sample.

CONCLUSIONS

The findings highlight potential targets for harm reduction education and interventions and emphasize the need for greater availability of readily accessible drug checking services in Aotearoa New Zealand.

Drug-related deaths at Australian music festivals

BACKGROUND

Illicit drug use is overrepresented in music festival attendees compared with the general population. Drug use often involves a wide range of substances with the potential to cause drug toxicity. Law enforcement-centred strategies intended to deter drug use and supply at these mass gatherings have been implemented throughout Australia. However, many have been criticised for their lack of effectiveness, with evidence suggesting that they can inadvertently increase the risk of drug harm. Drug deaths are often multifactorial, providing added challenges in the development of prevention strategies. This study aimed to determine the frequency of deaths involving alcohol and other drugs at music festivals in Australia and to identify potential risk factors that may inform future harm reduction strategies.

METHODS

A descriptive case series study was conducted using the National Coronial Information System (NCIS) to investigate drug-related deaths at music festivals throughout Australia between 1 July 2000 (Queensland from 1 January 2001) and 31 December 2019, using a list of keywords comprising music festival names and terms.

RESULTS

There were 64 deaths, of which most involved males (73.4%) aged in their mid-20s (range 15-50 years). Drug toxicity was the most common primary cause of death (46.9%) followed by external injuries (37.5%). The drug most commonly detected or reported as being used was MDMA (65.6%), followed by alcohol (46.9%) and cannabis (17.2%), with most cases reporting the use of two or more drugs (including alcohol) and 36% reporting a history of drug misuse in the coroner's findings. Most deaths were unintentional, with less than a fifth of cases (17.2%) involving intentional self-harm. Clinical intervention was involved in 64.1% of cases and most festivals occurred in inner city locations (59.4%).

CONCLUSIONS

The findings suggest that drug-related deaths at music festivals in Australia typically involve young people using multiple illicit substances in combination with alcohol. Most are unintentional and could potentially be prevented through the implementation of a range of harm reduction strategies, including mobile medical care, drug checking services, and increased consumer education and awareness.

Ethanol inhibits dopamine uptake via organic cation transporter 3: Implications for ethanol and cocaine co-abuse

Concurrent cocaine and alcohol use is among the most frequent drug combination, and among the most dangerous in terms of deleterious outcomes. Cocaine increases extracellular monoamines by blocking dopamine (DA), norepinephrine (NE) and serotonin (5-HT) transporters (DAT, NET and SERT, respectively). Likewise, ethanol also increases extracellular monoamines, however evidence suggests that ethanol does so independently of DAT, NET and SERT. Organic cation transporter 3 (OCT3) is an emergent key player in the regulation of monoamine signaling. Using a battery of in vitro, in vivo electrochemical, and behavioral approaches, as well as wild-type and constitutive OCT3 knockout mice, we show that ethanol's actions to inhibit monoamine uptake are dependent on OCT3. These findings provide a novel mechanistic basis whereby ethanol enhances the neurochemical and behavioral effects of cocaine and encourage further research into OCT3 as a target for therapeutic intervention in the treatment of ethanol and ethanol/cocaine use disorders.

Therapeutic role of psilocybin and 3,4-methylenedioxymethamphetamine in trauma: A literature review

With the Food and Drug Administration designation in 2017 of 3,4-methylenedioxymethamphetamine (MDMA) as a breakthrough therapy in post-traumatic stress disorder and psilocybin in treatment-resistant depression, psychedelic drugs have continued to garner the attention of researchers and clinicians for their promise of unmatched, rapid improvement in a multitude of psychiatric conditions. Classic psychedelic drugs including psilocybin, lysergic acid diethylamide, and ayahuasca, as well as non-classic drugs such as MDMA and ketamine, are currently being investigated for a potential therapeutic role in trauma, depressive disorders, and other psychopathologies. However, psilocybin and MDMA each have a functional profile well-suited for integration with psychotherapy. The present review focuses on psilocybin and MDMA in psychedelic-assisted therapy (PAT), as these studies compose most of the literature pool. In this review, we discuss the current and future uses of psychedelic drugs, with an emphasis on the role of MDMA and psilocybin in PAT in the setting of trauma and related comorbidities on the efficacy of psychedelic drugs across multiple psychiatric disorders. The article concludes with thoughts for future research, such as incorporating wearables and standardization of symptom scales, therapy styles, and assessment of adverse drug reactions.

Identifying Risk Factors for Hospitalization with Behavioral Health Disorders and Concurrent Temperature-Related Illness in New York State

Extreme temperature events are linked to increased emergency department visits, hospitalizations, and mortality for individuals with behavioral health disorders (BHD). This study aims to characterize risk factors for concurrent temperature-related illness among BHD hospitalizations in New York State. Using data from the NYS Statewide and Planning Research and Cooperative System between 2005-2019, multivariate log binomial regression models were used in a population of BHD hospitalizations to estimate risk ratios (RR) for a concurrent heat-related (HRI) or cold-related illness (CRI). Dementia (RR 1.65; 95% CI:1.49, 1.83) and schizophrenia (RR 1.38; 95% CI:1.19, 1.60) were associated with an increased risk for HRI among BHD hospitalizations, while alcohol dependence (RR 2.10; 95% CI:1.99, 2.22), dementia (RR 1.52; 95% CI:1.44, 1.60), schizophrenia (RR 1.41; 95% CI:1.31, 1.52), and non-dependent drug/alcohol use (RR 1.20; 95% CI:1.15, 1.26) were associated with an increased risk of CRI among BHD hospitalizations. Risk factors for concurrent HRI among BHD hospitalizations include increasing age, male gender, non-Hispanic Black race, and medium hospital size. Risk factors for concurrent CRI among BHD hospitalizations include increasing age, male gender, non-Hispanic Black race, insurance payor, the presence of respiratory disease, and rural hospital location. This study adds to the literature by identifying dementia, schizophrenia, substance-use disorders, including alcohol dependence and non-dependent substance-use, and other sociodemographic factors as risk factors for a concurrent CRI in BHD hospitalizations.

Trends in Mortality From Novel Psychoactive Substances as "Legal Highs": Gender Differences in Manner of Death and Implications for Risk Differences for Women

Introduction

This study aimed to examine drug-related deaths in the UK in which novel psychoactive substances (NPS) are an implicated substance, and to focus on female deaths in comparison with male deaths. While male overdoses dominate epidemiological statistics, there is an increase in female drug-related deaths and a narrowing of the gap between gender mortality rates which is to date unexplained.

Method

This study analyzed data from the National Programme for Substance Abuse Deaths (NPSAD) database that records drug-related deaths in the UK from coronial records. A dataset was constructed using parameters to capture all drug-related cases during the period 2007-2017 when NPS were legal and highly available in the UK, in order to capture deaths recorded among both regular and occasional drug users, and to include all cases recorded during that period regardless of NPS status in order to make comparisons. The final dataset comprised 10,159 cases, with 456 NPS-related deaths. Data for NPS and non-NPS were compared, and comparisons were made between cohorts by gender. The dataset also includes coronial narrative notes which allowed a qualitative analysis of NPS female deaths to add contextual explanation.

Results

The proportion of male NPS deaths is significantly higher than that for female NPS deaths but does not reflect the generalized difference between male and female drug-related mortality of this period studied. Demographic and outcome data by gender difference were significant for all drug-related deaths, but not for NPS-only deaths, indicating a greater homogeneity among NPS deaths by gender. Older women using NPS were more likely to have methadone or diazepam as another drug implicated and have established histories of drug misuse.

Conclusion

Where NPS have been used, differences in drug death profiles are less likely to be accounted for by gender than other demographic or behavioral differences more typically found in opiate deaths. The social and health problems of older women may be key characteristics that differentiate female deaths from male deaths. These findings also support evidence of increasing uptake of NPS among older established drug users that adds further risk to polydrug use.
