This study aimed to visualize the network of themes that arise within cancer patients’ reported experiences with cannabis.Materials and methodsData was collected via an online survey of 65 patients who self-reported the use of cannabis in their treatment f…
Open article record in new tab ↗Hemp products [cannabis with ≤0.3% Δ9-tetrahydrocannabinol (Δ9-THC)] are federally legal, but few controlled experiments have explored drug test results, pharmacokinetics, or pharmacodynamics. Healthy adults (n = 60) self-administered 1.5 mL medium-chain triglyceride (MCT) oil containing 100 mg cannabidiol (CBD) and either 0, 0.5, 1, 2, 2.8, or 3.7 mg Δ9-THC (n = 10 per group). The study included an 8-hour acute d…
Background Cannabis is among the most widely consumed psychoactive substances, with increasing consumption due to growing legalization for medical and non-medical use. As access expands, healthcare providers are faced with clinical challenges, despite variability in knowledge and attitudes on cannabis use in clinical practice. Methods We conducted an anonymous, cross-sectional web-based survey of U.S. healthcare p…
Open article record in new tab ↗Cannabidiol (CBD) is widely perceived as a safe and effective treatment for a growing list of health indications and use for general wellness. Evidence for its safety and efficacy comes from a variety of sources, including preclinical studies, clinical trials, and observational studies of real-world evidence. The challenge in interpreting these data is that CBD products are diverse with respect to format, formulat…
Open article record in new tab ↗Cannabis and its major constituents, Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD), are being widely used to treat sleep disturbances. However, THC can cause acute cognitive and psychomotor impairment and there are concerns that driving and workplace safety might be compromised the day after evening use. Here, we examined possible 'next day' impairment following evening administration of a typical medicinal…
Background Cannabis may be an alternative or adjunct to opioid therapy for chronic pain. However, there are limited data on patterns of opioid medication and medical cannabis use. The current study investigated the feasibility of using Ecological Momentary Assessment (EMA) to assess patterns of prescription opioids and medical cannabis among individuals experiencing chronic pain. Method The study included 133 part…
Open article record in new tab ↗Background and objective: Commercially available cannabidiol (CBD) products are increasingly being used for medicinal purposes, including for the treatment of various neurological conditions, but there are growing concerns around adherence to quality control measures that protect consumers. This study was conducted to assess the purity and label accuracy of commercially available CBD products. Methods: Commerciall…
Open article record in new tab ↗The potential synergistic effects of combining cannabinoids and opioids for analgesia has received considerable attention. No studies to date have evaluated this combination in patients with chronic pain. The present study aimed to evaluate the combined analgesic and drug effects of oral opioid (hydromorphone) and delta-9-tetrahydrocannabinol (dronabinol), as well as their effects on physical and cognitive functio…
The legalization of cannabis for medicinal and non-medicinal purposes, and the corresponding increase in diversity of cannabis products, has resulted an urgent need for cannabis regulatory science. Among the most pressing needs is research related to impairment due to cannabis exposure, especially on driving performance. The present project was designed to evaluate the impact of oral and vaporized cannabis, when a…
Importance Products containing cannabinoids such as cannabidiol (CBD) have proliferated since 2018, when the Agriculture Improvement Act removed hemp (ie, cannabis containing <0.3% Δ9-tetrahydrocannabinol [THC]) from the US controlled substances list. Topical cannabinoid products can be purchased nationwide at retail stores and over the internet, yet research on these products is scarce. Objective To evaluate the…
Aim: To characterize perceived benefits and challenges experienced by medicinal cannabis users. Methods: An anonymous online survey collected demographics, health information, and open-ended responses from medicinal cannabis users regarding perceptions, motivations, and experience of treatment. Qualitative open-ended responses were thematically analyzed. Results: Respondents (N = 808) were predominantly White (79%…
Open article record in new tab ↗Due to a lack of published pharmacokinetic (PK) and/or pharmacodynamic (PD) data, informed physician and patient decision-making surrounding appropriate dosing of cannabis for medical purposes is limited. This Phase 1, multiple-dose study evaluated the safety, tolerability, PK and PD of Spectrum Red softgels (2.5 mg Δ9-tetrahydrocannabinol (THC) and <0.25 mg cannabidiol (CBD)). Participants (n = 41) were randomize…
Open article record in new tab ↗Cannabis use alters sperm DNA methylation, but the potential reversibility of these changes is unknown. Semen samples from cannabis users and non-user controls were collected at baseline and again following a 77-day period of cannabis abstinence (one spermatogenic cycle). Users and controls did not significantly differ by demographics or semen analyses. Whole-genome bisulfite sequencing identified 163 CpG sites wi…
Open article record in new tab ↗Background: Anxiety and depressive disorders are highly prevalent. Patients are increasingly using medicinal cannabis products to treat these disorders, but little is known about the effects of medicinal cannabis use on symptoms of anxiety and depression. The aim of the present observational study was to assess general health in medicinal cannabis users and non-using controls with anxiety and/or depression. Method…
Open article record in new tab ↗Introduction: Despite widespread legalization, the impact of medicinal cannabis use on patient-level health and quality of life (QOL) has not been carefully evaluated. The objective of this study was to characterize self-reported demographics, health characteristics, QOL, and health care utilization of Cannabis Users compared with Controls. Methods: A longitudinal, cross-sectional web-based survey study was comple…
Open article record in new tab ↗Background The lack of an agreed international minimum approach to measuring cannabis use hinders the integration of multidisciplinary evidence on the psychosocial, neurocognitive, clinical and public health consequences of cannabis use. Methods A group of 25 international expert cannabis researchers convened to discuss a multidisciplinary framework for minimum standards to measure cannabis use globally in diverse…
Background The main psychoactive component of cannabis, delta-9-tetrahydrocannabinol (THC), can impair driving performance. Cannabidiol (CBD), a non-intoxicating cannabis component, is thought to mitigate certain adverse effects of THC. It is possible then that cannabis containing equivalent CBD and THC will differentially affect driving and cognition relative to THC-dominant cannabis. Aims The present study inves…
Introduction: Cannabis has been historically classified as a hallucinogen. However, subjective cannabis effects do not typically include hallucinogen-like effects. Empirical reports of hallucinogen-like effects produced by cannabis in controlled settings, particularly among healthy research volunteers, are rare and have mostly occurred after administration of purified Δ-9 tetrahydrocannabinol (THC) rather than who…
Open article record in new tab ↗Introduction: The proliferation of cannabis dispensaries within the United States has emerged from patient demand for the legalization of cannabis as an alternative treatment for a number of conditions and symptoms. Unfortunately, nothing is known about the practices of dispensary staff with respect to recommendation of cannabis strains/concentrations for specific patient ailments. To address this limitation, the…
