Newest firstThe growing use of e-cigarettes as vehicles for illicit drug delivery has created an urgent challenge for forensic surveillance and public health in East Asia. This study analyzed 496 e-liquid samples seized by law-enforcement agencies in Eastern Taiwan (January-July 2025) using a full-scan GC-MS workflow validated in accordance with ANSI/ASB forensic toxicology standards. Overall, 80.8% of samples (n = 401) teste…
Open article record in new tab ↗Chemsex refers to the intentional use of psychoactive substances to enhance, explore, or alter sexual experiences. The use of geolocation apps, and its link with physical, psychological, and social harms for the individual as well as society has been described 'Polydrug use'-combining multiple substances to amplify or diversify effects-is frequently reported across these groups. This article provides a comprehensi…
Studies analyzing the prevalence of associated substance use are limited. Currently, the World Health Organization (WHO) defines polydrug use as the concurrent (simultaneous use) or sequential (use of one drug followed by another) abuse of more than one drug or type of drug, with dependence on at least one. Associated drug consumption can exacerbate the adverse effects and complicate the clinical management of pat…
Open article record in new tab ↗Anabolic-androgenic steroids (AASs) are a subclassification of image performance enhancing drugs (IPEDs). While AAS use is most prevalent among people in athletics, there is also high lifetime prevalence of AAS use among prisoners. This study reports the qualitative detection of AASs in seized samples from the Scottish prisons from 2019-2023. Additionally, methods were developed for the quantitative analysis of AA…
Background Substance use among adolescents is a public health problem, and the simultaneous use of multiple substances aggravates this problem. Although the facilitators of specific substance use in adolescents have been widely investigated, polydrug use is a less common topic. Likewise, the role that the origin of the information available to adolescents regarding substance use plays in relation to polydrug use i…
OBJECTIVE: This study examined the nature and prevalence of polydrug use in 12-14 year old Australians. METHOD: Three Australian school surveys (2006, n=4091; 2009, n=5635; 2017, n=1539; age 12-14 years) spanning 11 years were used. Substances included alcohol, tobacco, cannabis, inhalant, and other illicit substances. Risk factors included depressed mood, low emotional control, poor family management and conflict…
Polydrug use is a frequent pattern of consumption in Europe. This behavior has mainly been analyzed within restricted groups; more rarely in large populations. Current polydrug use is less studied than simultaneous use. This study focused on the concurrent assumption of polydrug among drivers using hair matrix. Hair matrix, for its biological characteristics, allows to identify illicit drug use more often than oth…
Open article record in new tab ↗This study compares the prevalence of drug use and the typologies of polydrug use (PDU) in men who have sex with men (MSM) and general population men (GPM). Participants were men aged 16-64, living in the provinces of Madrid and Barcelona: 1720 were recruited in a GPM survey, and 2658 were HIV-negative MSM from HIV/STIs diagnosis services. Lifetime and last-year prevalence of drug use and prevalence ratios (PRs) o…
Background While research has consistently identified an association between long-term cannabis use and memory impairments, few studies have examined this relationship in a polydrug context (i.e., when combining cannabis with other substances). Aims: In this preliminary study, we used event-related potentials to examine the recognition process in a visual episodic memory task in cannabis users (CU) and cannabis po…
Background: Impairments in various subdomains of memory have been associated with chronic cannabis use, but less is known about their neural underpinnings, especially in the domain of the brain's oscillatory activity. Aims: To investigate neural oscillatory activity supporting working memory (WM) in regular cannabis users and non-using controls. We focused our analyses on frontal midline theta and posterior alpha…
BACKGROUND: Despite a decrease in driving under the influence of alcohol (DUIA) prevalence over the past decades, DUIA prevalence still remains high in the United States. To date, there is limited research examining whether different types of substance users have different trends in DUIA. This study sought to assess trends and variables associated with DUIA by substance use type. METHODS: National Survey on Drug U…
Open article record in new tab ↗Research into comorbidity of alcohol and cannabis use disorders has resulted in inconsistent findings, especially among simultaneous users, who used alcohol and cannabis together on a single occasion. This study investigated the association of alcohol and cannabis use disorders among simultaneous users using a network perspective, which considers direct relationships between symptoms. We used a subset of simultane…
Open article record in new tab ↗The combined use of cannabis and tobacco is frequent in Europe. Few studies have nonetheless explored this pattern of consumption and its relationship with academic achievement in Spanish population. The aim of the present study was to analyze (1) the frequency of four patterns of polydrug use the last year (non-dual users of cannabis and tobacco; concurrent users: cannabis and tobacco separately; simultaneous use…
Open article record in new tab ↗Elevated schizotypy relates to similar cognitive attenuations as seen in psychosis and cannabis/polydrug use. Also, in schizotypal populations cannabis and polydrug (including licit drug) use are enhanced. These cognitive attenuations may therefore either be a behavioral marker of psychotic (-like) symptoms or the consequence of enhanced drug use in schizotypal populations. To elucidate this, we investigated the l…
Open article record in new tab ↗Background: Alcohol use and illicit drug use peak during young adulthood (around 18–29 years of age), but comparatively little is known about polydrug use in nationally representative samples of young adults. Drawing on a nationally representative cross-sectional survey (Australian National Drug Strategy Household Survey), this study examines polydrug use patterns and associated psychosocial risk factors among you…
