Newest firstReliable and traceable quantification of cannabinoids is essential for forensic, regulatory, and quality control applications involving cannabis-derived products. However, the limited availability of certified reference materials (CRMs), particularly for minor cannabinoids such as cannabinol (CBN), remains a major analytical challenge. In this work, an integrated analytical and preparative strategy is presented fo…
Open article record in new tab ↗PURPOSE: Cannabis use is increasing among older adults. Given reported associations between delta-9-tetrahydrocannabinol (THC) and increased acute heart rate, there is concern regarding the impact of cannabis on cardiovascular health in older adults. Engaging in regular physical activity (PA) is associated with reduced heart rate and cardiovascular disease risk, but it has yet to be explored whether PA status infl…
Open article record in new tab ↗Delta-8 THC is a psychoactive cannabinoid typically synthesized from hemp, with similar intoxicating effects as delta-9 THC. Surging public interest alongside the lack of federal regulation of delta-8 THC has led to an unclear legal landscape and increasing safety concerns. Educating young adults about the dangers of delta-8 THC is imperative. The current study investigated the effects of a brief educational video…
Introduction Changes in regulatory policies regarding cannabis have led to a rapid expansion of the cannabis market and a substantial increase in cannabis sales. This study examined medicinal and recreational cannabis demand in a hypothetical legalisation scenario in Spain among people who use over-the-counter CBD, THC only and CBD + THC. Methods A cross-sectional study comprising 1492 participants aged 16-30. The…
Cannabinoid use and misuse has been rising since 2011, and the development of new cannabinoid derivatives, partially due to the passage of the Farm Bill in 2018, and more relaxed legislation, has complicated testing for this drug class. The impact on child welfare in homes with cannabis substance use remains a concern, so detection of environmental exposure to cannabinoids is hugely beneficial. This article report…
Open article record in new tab ↗Accurate quantification of Δ9-tetrahydrocannabinol (THC) and Δ9-tetrahydrocannabinolic acid (THCA) across diverse cannabis- and hemp-derived products remains challenging due to severe matrix effects, wide concentration variability, and the need for matrix-matched calibration in traditional LC-MS workflows. Here, we develop an in-sample calibration curve (ISCC) method based on multiple isotopologue reaction monitor…
Fibromyalgia is a chronic disorder characterised by widespread pain and other symptoms that substantially impact the quality of life. This double-blind, randomised, placebo-controlled trial primarily assessed feasibility (procedures and intervention adherence) and safety/tolerability of a 1:1 delta-9-tetrahydrocannabinol:cannabidiol (THC:CBD) cannabis oil (10 mg/mL each) in 24 adults with fibromyalgia, with second…
Purpose Glaucoma is a leading cause of irreversible blindness globally, primarily driven by elevated intraocular pressure (IOP). Still, some patients progress despite significant IOP lowering, potentially due to impaired ocular blood flow. This study aimed to evaluate the effects of dronabinol, a synthetic tetrahydrocannabinol derivative, on ocular blood flow in primary open-angle glaucoma (POAG) patients. Methods…
Importance The primary psychoactive compound in cannabis, ∆9-tetrahydrocannabinol (THC) induces intoxication and functional impairment, raising safety concerns in driving. The traditional impairment detection method, behavioral field sobriety tests (FSTs), are subject to bias. Objective To determine whether resting-state functional near-infrared spectroscopy (fNIRS) can detect THC-related impairment with greater a…
Δ9-tetrahydrocannabinol (THC), the main psychoactive compound in cannabis, and other drug molecules that have large molar masses, are often described as 'nonvolatile' and are presumed to be carried in exhaled breath aerosols. Large variabilities in THC concentrations in breath have been measured with devices that only collect aerosols; it is possible that neglecting the vapor phase could be responsible. Partitioni…
The persistence of HIV latent reservoir is the major challenge to HIV cure because latent viruses serve as sources for viral rebound upon ART cessation. Mechanisms regulating viral persistence are not well understood; thus, there is a compelling need for research focusing on addressing the knowledge gap related to HIV persistence. The present study focuses on the effect of extracellular condensates (ECs) on latent…
Background In recent decades, the potency of cannabis resin increased globally, raising concerns, as higher potency has been associated with increased risk of psychiatric harms at the individual level. The aim here was to examine whether changes over time in the potency of seized cannabis resin samples were associated with psychiatric harms at the population level. Methods Data on ∆-9-tetrahydrocannabinol (THC) co…
Background Cannabis use among young adults has reached the highest levels ever recorded. Evidence indicates that acute Δ9-tetrahydrocannabinol (THC) disrupts brain connectivity. Few studies have examined this on a whole-brain level. We examined the effects of a single moderate dose of THC on resting-state functional brain networks among young adult cannabis users. Methods In a within-subject, double-blind, randomi…
Neuroinflammation is a hallmark of multiple sclerosis (MS). MS is marked by glial cell activation, autoreactive T cells, and the release of pro-inflammatory cytokines and free radicals. Current therapeutic strategies aim to modulate the immune response using disease-modifying therapies, to slow disease progression. The specific aims of this study were: (a) to investigate the effect of cannabinoid acids on the rele…
Background Alzheimer's disease (AD) remains the most prevalent cause of dementia, yet no existing treatment effectively prevents its onset. Current therapies primarily aim to slow disease progression or manage symptoms, leaving a critical gap in preventive strategies. Recent findings suggest that ultra-low-dose tetrahydrocannabinol (ULD-THC) may exert neuroprotective effects without the adverse consequences associ…
Background Most substance users are polysubstance users; however, little is known about how the combined use of different drugs affects the course of substance use disorder or effectiveness of treatment. Notably, co-use of cannabis and nicotine is very common, and we previously demonstrated that nicotine enhances the self-administration of a synthetic cannabinoid receptor agonist and the primary psychoactive phyto…
Numerous exocrine glands play key physiological roles in the body that include tearing, salivation, and lactation, as well as the control of body temperature via sweating. Malfunction of sweat glands can be deeply problematic or-in the case of anhidrosis-life-threatening. The prevalence of sweating disorders is high, affecting millions. The few available therapies are generally of limited effectiveness. Several li…
Open article record in new tab ↗Recently developed dried blood analysis methods for cannabinoid quantitation utilize small blood volumes, making them microsampling-compatible, but are limited by hematocrit-related bias for dried blood spots (DBSs) and higher consumable costs for volumetric absorptive microsampling (VAMS®). To address these issues, we developed a highly sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method ca…
Background Medical cannabis is now commonly prescribed for a range of chronic health conditions. Many medical cannabis products contain delta-9-tetrahydrocannabinol (THC), the intoxicating component in cannabis, though it is unclear whether these products produce impairment when used as prescribed and at therapeutic doses. With current Australian laws prohibiting driving with any amount of THC in one's system, thi…
Open article record in new tab ↗Medicinal cannabis use is increasing worldwide, yet its impacts on driving safety in frequent users are not clearly understood. A more comprehensive understanding of the effects of THC on driving behaviour in frequent users is needed to guide drug driving policy and evidence-based advice for medicinal cannabis consumers. This study investigated the acute effects of orally ingested THC oil on medicinal cannabis use…
