Comparing Motivations for Anabolic-Androgenic Steroid Use Among an International Sample of Men
Introduction: Anabolic-androgenic steroids (AAS) are used for medical and non-medical purposes. Although the motivations underpinning AAS consumption among men have been explored, less is understood about age-related differences. This research compares AAS use motivations between men aged <40 and ≥40 years. Method: Data were drawn from the 2024 Global Drug Survey (GDS2024), an international, self-selected online convenience sample, comprising 1,1…
Modifiable Determinants of Psychological Harms among Male Image and Performance Enhancing Drug Consumers
BACKGROUND: Image and performance-enhancing drugs (IPEDs) are linked to undesirable psychological effects (e.g., depression), influenced by various factors. This study examined associations between non-modifiable (e.g. age) and modifiable (e.g. prescription status, dosage regimen, polypharmacy load) factors and psychological effects among male IPED consumers. METHODS: Data from 785 males (median age = 30) reporting past-year IPED consumption in t…

The Trenbolo(g)ne Sandwich
Making ‘safer injecting’ matter for people who inject image and performance enhancing drugs
Image and performance-enhancing drugs (IPEDs) are primarily injected intramuscularly or subcutaneously, yet traditional harm reduction strategies, focused on blood-borne virus prevention, often overlook the specific health enhancement goals of people who use IPEDs. This study advocates for a collaborative approach to safer injecting practices, informed by the lived-living experiences of people injecting IPEDs, to develop targeted messaging that a…
Distinct Drinking Patterns, Help Seeking, and Alcohol-Related Regret in ADHD, Autism, and AuDHD
ADHD is associated with higher alcohol use, while autism is linked to lower use, but little is known about patterns among individuals with both conditions (AuDHD), particularly when accounting for mental health. This study examined whether alcohol consumption, drunkenness, regret, and help-seeking differ across ADHD, autism, AuDHD, and controls, and whether regret predicts intentions to reduce drinking. Using data from the 2021 Global Drug Survey…
Psychedelics and Sexual Trauma
Psychedelics are theorized to enhance emotional openness and interpersonal attunement, but their effects in sexual contexts - particularly among those with a history of sexual trauma - remain underexplored. This study investigated whether individuals who had used psychedelics to cope with or overcome sexual trauma (Psy-CST) reported different experiences of sexual communication and emotional connection compared to those who had not (No-Psy-CST). …

The relationship between cryptomarket drug purchase, social networks and adverse drug events
People who reported purchasing drugs from cryptomarkets more commonly reported having no drug-using network, and cryptomarket purchase was associated with reported adverse events. Our results support the notion that cryptomarket use increases drug-related harm, but further disentanglement of multiple complex mechanisms is needed in future research
Sweating for Sobriety
Despite various interventions available for substance use disorders, relapse rates remain substantial and, therefore, alternative strategies for attenuating dependence are needed. This study examined the associations between exercise frequency, illicit substance use, and dependence severity among a large sample of people who use drugs. The study utilized data from the Global Drug Survey 2018 ( N = 57,110) to investigate the relationship between e…
Associations between mental illness and non-medical use of prescription opioids among a sample of people who use drugs in Australia and New Zealand

They sent it away for testing and it was all bunk”
AAS consumers recognise the significance of monitoring their AAS use and seek a service that can not only assist them in making informed decisions regarding AAS usage but also potentially contribute to the knowledge of the wider AAS-consuming community. These findings underscore the importance of tailored education, drug checking services, and harm reduction measures to address the diverse needs of AAS consumers
Better Bang for the Buck? Generalizing Trust in Online Drug Markets
Past research into illicit online markets suggests that trust is produced by governance, reputation systems and the formation of social ties. In this paper, we draw on accounts of abstract and institutional trust, examining whether using a market is associated with general positive beliefs about product quality. Using data from the 2018 Global Drug Survey (n = 25,471) we utilize propensity score matching and multilevel linear regression to examin…

Respondents were asked about their relationship with the drinker, if they shared a household, and the level of negative impac…
Differences in Trouble per Liter of Different Alcoholic Beverages —A Global Comparison with the Genacis Dataset
Different alcoholic beverages are seen as causing more or less trouble, with spirits historically often seen as the most troublesome. Differences in “trouble per liter” could reflect differences in the beverages themselves (e.g., faster effect of stronger beverages, additives/contaminants in informal beverages), or could reflect characteristics of those drinking each beverage. Using two alternative definitions of beverage choice and measures of p…

Short-term changes in nightlife attendance and patron intoxication following alcohol restrictions in Queensland, Australia
Earlier cessation of alcohol sales and stopping the sale of rapid intoxication drinks after midnight was associated with people arriving in Fortitude Valley earlier. Though legislative loopholes allowed some venues to continue trading to 5 am, the proportion of people in the precinct who were highly intoxicated decreased after the restriction. Further measurement will be required to determine whether the reduction has persisted
