Newest firstCannabidiol (CBD) is approved as an adjunctive treatment of seizures associated with Dravet syndrome, Lennox-Gastaut Syndrome, and tuberous sclerosis. Its therapeutic and adverse effects are thought to arise, at least partly, from a pharmacokinetic interaction with clobazam, another anti-seizure medication (ASM). The goal of this study was to evaluate the intrinsic anti-epileptic and sedative properties of CBD. A…
Open article record in new tab ↗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…
Oral cannabidiol (CBD) treatment has been suggested to alleviate severe symptoms of autism spectrum disorder (ASD). While many CBD preparations have been studied in clinical trials involving ASD, none has used purified CBD preparations or preparations approved by the U.S. Food and Drug Administration, nor have they focused on children with ASD with higher support needs. Previous studies have identified several can…
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 ↗Lymphatic transport of drugs after oral administration is an important physiological process in highly lipophilic compounds, such as cannabidiol (CBD). The majority of lymphatic transport studies have been historically conducted in anesthetized rats. However, this animal model differs significantly from the humans regarding both anatomical and physiological features. The aim of this study was therefore to develop…
Background Cannabis has shown mixed results in its association with alcohol urge, which may be explained by individual differences. One such factor, working memory capacity (WMC) is associated with drug-related cue reactivity and implicated in alcohol use and problems. In the current study, we examined whether WMC moderates the acute effect of cannabis on alcohol urge in a randomized placebo-controlled crossover t…
Open article record in new tab ↗Given the increasing availability of high-potency Δ9-tetrahydrocannabinol (Δ9-THC) products, understanding potency-related effects of Δ9-THC on driving performance is an important public safety issue. This randomized, double-blind, placebo-controlled, within-subjects trial examined the effects of smoked cannabis with varying Δ9-THC concentrations on simulated driving. Adults aged 19–45 who regularly used cannabis…
Objective To assess the efficacy of cannabis for the treatment of acute migraine. Background Preclinical and retrospective studies suggest cannabinoids may be effective in migraine treatment. However, there have been no randomized clinical trials examining the efficacy of cannabinoids for acute migraine. Methods In this randomized, double-blind, placebo-controlled, crossover trial, adults with migraine treated up…
Background Emerging evidence indicates that cannabidiol (CBD) may offer meaningful therapeutic benefits across neurological, pain, and psychiatric disorders. Cannabidiol is already approved for the treatment of pediatric epilepsy. Owing to its high lipophilicity, it is typically delivered in oil-based formulations to overcome the low oral bioavailability of pure CBD. However, pharmacokinetic (PK) and safety data r…
There has been a growing interest in the use of cannabinoids in horses in recent years. Several studies have reported on the pharmacokinetics of cannabidiol (CBD) in horses. However, cannabidiolic acid (CBDA) has received less attention, despite limited evidence suggesting clinically beneficial effects in other species. Horses were administered 3 mg/kg of CBD, 3 mg/kg of CBDA, and a placebo per os in a crossover d…
Objective Alcohol and cannabis co-use is the most common form of polysubstance use in the U.S. Some evidence suggests that there is an association between cannabis use and reduced alcohol consumption, however data on this topic are mixed. Further research is needed to elucidate the individual factors that determine whether cannabis substitutes for alcohol. Method This study is an exploratory analysis of data from…
Open article record in new tab ↗Aims Cannabidiol (CBD), the main non-intoxicating compound from the cannabis plant, is regularly used by patients with chronic pain who also take analgesics. CBD has previously been shown to inhibit CYP-mediated drug metabolism. This study aimed to characterize the potential pharmacokinetic interaction of CBD with amitriptyline and tramadol, two commonly used analgesics. Methods This was an open-label, fixed-seque…
Objectives: This study investigated the effects of 2-week ingestion of hemp fiber (high and low doses) versus placebo bars on gut permeability and plasma metabolite shifts during recovery from 2.25 h intensive cycling. Hemp hull powder is a rich source of two bioactive compounds, N-trans-caffeoyl tyramine (NCT) and N-trans-feruloyl tyramine (NFT), with potential gut health benefits. Methods: The study participants…
In patients with schizophrenia, cannabis use exacerbates symptoms and can lead to a relapse of psychosis. Some experimental studies in healthy volunteers suggest that pre-treatment with cannabidiol (CBD) may reduce these effects, but others do not. Here, we investigated whether pre-treatment with CBD ameliorates the acute adverse effects of cannabis in patients with schizophrenia. Participants (n = 30) had schizop…
Study objectives Current treatments for obstructive sleep apnea (OSA) are ineffective or not tolerated in a proportion of patients. Other therapeutic options are needed and pharmaceuticals may provide an alternative. This randomized, double-blind, placebo-controlled, crossover study examined the effect of a combination of acetazolamide and dronabinol (IHL-42X) at low, medium, and high doses on OSA severity. Method…
ObjectivesFeline osteoarthritis (OA) is a common, degenerative joint condition that is an important cause of chronic pain in cats. Cannabinoids have shown potential in reducing pain and inflammation in OA, but research in cats is limited. This study aimed to assess the safety and efficacy of a cannabidiol (CBD)/cannabidiol acid (CBDA) paste would in cats with OA. We hypothesised that CBD/CBDA paste would reduce pa…
Our previous studies showed that dexamphetamine, an indirect dopamine agonist, widens Stimulus Binding Windows (BWs) in healthy subjects. The present study aimed to investigate the effect of nabilone, a synthetic cannabinoid agonist, on the BWs in a unimodal illusion: the tactile funneling illusion (TFI). The study also aimed to study the association between tactile illusion with psychometric scores. Healthy parti…
Rationale Despite the critical role of choice processes in substance use disorders, the neurobehavioral mechanisms guiding human decisions about drugs remain poorly understood. Objectives We aimed to characterize the neural encoding of subjective value (SV) for cannabis versus non-drug rewards (snacks) in people who use cannabis on a near-daily/daily frequency (PWUCF) and assessed the impact of cannabis and snack…
Open article record in new tab ↗Alcohol use disorder (AUD) is a prevalent psychiatric condition characterised by problematic alcohol consumption and craving, necessitating the exploration of novel therapeutic interventions. Cannabidiol (CBD), a non-psychoactive component of cannabis, has shown potential in modulating neural processes associated with substance use disorders including AUD. This study aimed to investigate the effect of CBD on alcoh…
