Newest firstPain is prevalent among people with HIV (PWH), and many PWH who experience pain also use substances (illicit drug and/or unhealthy alcohol use). While cocaine use and cocaine and alcohol co-use are prevalent in this population, their effects on pain in PWH are unknown. This study aims to investigate the association of cocaine use and co-use of cocaine and alcohol with pain interference among PWH. We completed a se…
Open article record in new tab ↗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…
There is renewed interest in investigating the analgesic properties of cannabis for musculoskeletal joint pain; however, available data remain limited. This cross-sectional study was designed with the objective of evaluating patients' perceptions regarding the effect of cannabis on arthritis pain. Patients with arthritis pain presenting at one of three orthopedic clinics were asked to complete the study questionna…
Prescription opioid misuse is a significant public health concern among individuals with chronic pain. Treating severe pain often requires high doses of opioids, increasing the risk of developing an opioid use disorder. Cannabidiol (CBD) is a non-intoxicating component of cannabis that has shown therapeutic potential without abuse liability. This study investigated the effects of CBD on oxycodone self-administrati…
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…
The aim of this study was to assess changes in validated patient-reported outcome measures after initiation of cannabis-based medicinal products (CBMPs) and the safety of CBMPs in patients with inflammatory arthritis. A prospective case series from the UK Medical Cannabis Registry was analyzed. The primary outcomes changes were in Brief Pain Inventory, McGill Pain Questionnaire, EuroQol 5-dimension 5-level (EQ-5D-…
Chronic low back pain (CLBP) affects over half a billion people worldwide. Current pharmacologic treatments offer limited efficacy and carry substantial risks, warranting the development of safe and effective alternatives. This multicenter, randomized, placebo-controlled phase 3 trial evaluated the efficacy and safety of VER-01 in CLBP. It enrolled 820 adults with CLBP (VER-01, n = 394; placebo, n = 426) and inclu…
Introduction Chronic pain remains a challenge, with standard therapies often providing inadequate pain relief and causing undesirable side effects. Medicinal cannabis has emerged as promising alternative. This study assessed the impact of a cannabis hybrid extract on pain intensity and quality of life in daily clinical use. Methods ESCAPE was an observational study and included patients aged ≥ 18 years with chroni…
Introduction Chronic pain (CP) affects 35.0%-51.3% of the UK population, with 67%-88% reporting sleep disturbances. Cannabis-based medicinal products (CBMPs) have shown therapeutic potential in managing CP. Evidence suggests poor sleep worsens pain perception; therefore, this study aimed to assess patient-reported outcome measures (PROMs) following CBMP treatment in CP patients with and without co-morbid sleep imp…
Open article record in new tab ↗Background Since March 1, 2017, medical cannabis (MC) can be prescribed nationwide in Germany. To date, there have been a number of qualitatively different studies on the effectiveness of MC in fibromyalgia syndrome (FMS). Objective The aim of the study was to investigate the effectiveness of THC in the course of interdisciplinary multimodal pain therapy (IMPT) on pain and several psychometric variables. Materials…
Open article record in new tab ↗Persons with HIV (PWH) experience high levels of pain. We examined the relationship of pain severity with use of cannabis and prescription opioids among PWH. This cross-sectional study evaluated associations between self-reported pain (moderate/severe vs mild/none) and cannabis and prescription opioid use in a primary care sample of PWH enrolled in an alcohol use treatment study at Kaiser Permanente, San Francisco…
Hand osteoarthritis (OA) is an irreversible degenerative condition causing chronic pain and impaired functionality. Existing treatment options are often inadequate. Cannabidiol (CBD) has demonstrated analgesic and anti-inflammatory effects in preclinical models of arthritis. In this open-label feasibility trial, participants with symptomatically active hand OA applied a novel transdermal CBD gel (4% w/w) three tim…
Odontogenic pain can be debilitating, and nonopioid analgesic options are limited. This randomized placebo-controlled clinical trial aimed to assess the effectiveness and safety of cannabidiol (CBD) as an analgesic for patients with emergency acute dental pain. Sixty-one patients with moderate to severe toothache were randomized into 3 groups: CBD10 (CBD 10 mg/kg), CBD20 (CBD 20 mg/kg), and placebo. We administere…
Open article record in new tab ↗Objective This study pools two cohorts of workers in Ontario interviewed 18 months following a disabling work-related injury to estimate the association between pain severity, cannabis use, and disability benefit expenditures. Methods Among 1650 workers, disability benefit expenditures obtained from administrative records were combined with self-reported measures of pain symptoms and cannabis use. Disability benef…
Abstract Visual analogue scales are widely used to measure subjective responses. Norris' 16 visual analogue scales (N_VAS) measure subjective feelings of alertness and mood. Up to now, different scientists have clustered items of N_VAS into different ways and Bond and Lader's way has been the most frequently used in clinical research. However, there are concerns about the stability of this clustering over differen…
Pain induced by inflammation and nerve injury arises from abnormal neural activity of primary afferent nociceptors in response to tissue damage, which causes long-term elevation of the sensitivity and responsiveness of spinal cord neurons. Inflammatory pain typically resolves following resolution of inflammation; however, nerve injury-either peripheral or central-may cause persistent neuropathic pain, which freque…
Background Human immunodeficiency virus type-1 (HIV-1) and opiates cause long-term inflammatory insult to the central nervous system (CNS) and worsen disease progression and HIV-1-related neuropathology. The combination of these proinflammatory factors reflects a devastating problem as opioids have high abuse liability and continue to be prescribed for certain patients experiencing HIV-1-related pain. Methods Here…
Background Dementia is a neurological condition that affects the cognitive and functional ability of the brain and is the leading cause of disability among those aged 65 years and above. More effective ways to manage dementia symptoms are needed because current treatment options (antidepressants and antipsychotics) can be ineffective and are associated with substantial side effects, including increased rate of mor…
Pain is susceptible to various cognitive factors. Suppression of pain by hunger is well known, but the effect of food intake after fasting (i.e. refeeding) on pain remains unknown. In the present study, we examined whether inflammatory pain behavior is affected by 24 h fasting and 2 h refeeding. In formalin-induced acute inflammatory pain model, fasting suppressed pain behavior only in the second phase and the ana…
Open article record in new tab ↗Background Targeting the endocannabinoid system has emerged as an effective strategy for the treatment of inflammatory and neurological diseases. Unlike the inhibition of the principal 2-arachidonyl glycerol (2-AG) hydrolytic enzyme monoacylglycerol lipase (MAGL), which leads to 2-AG overload and cannabinoid receptor desensitization, selective inhibition of the minor 2-AG hydrolytic enzyme alpha, beta-hydrolase do…
