Abstract Introduction: Diabetic peripheral neuropathy (DPN) represents a prevalent neurological complication affecting millions of patients globally. This clinical investigation evaluated the therapeutic efficacy and safety profile of a novel transdermal medical cannabis formulation (THC:CBD:CBN) in treating painful DPN of the lower extremities. Methods: This phase III, double-blind, placebo-controlled, randomized clinical trial was conducted at Don Chan Hospital, Thailand, enrolling 100 participants over a 12-week intervention period. Using a computer-generated randomization sequence, participants were allocated to receive either the standardized cannabis formulation or a matched placebo. The primary outcome measure comprised pain intensity assessment using the validated Thai version of the Neuropathic Pain Symptom Inventory (NPSI-T). Secondary outcomes...

Abstract Cancer pain (CP) is a prevalent condition with limited pharmacotherapeutic options. Cannabis-based medicinal products (CBMPs) have shown analgesic effects, but their efficacy in CP remains contentious. This study aims to evaluate the change in patient-reported outcome measures (PROMs) and adverse events (AEs) in CP patients treated with CBMPs. A case series was conducted using prospectively collected clinical data from the UK Medical Cannabis Registry. Primary outcomes were the changes in the Brief Pain Inventory (BPI), pain visual analogue scale (Pain-VAS), EQ-5D-5L, Generalized Anxiety Disorder-7 (GAD-7), Patient Global Impression of Change (PGIC) and Single-Item Sleep Quality Scale (SQS) questionnaires from baseline to 1, 3,...

Delta-9-tetrahydrocannabinol (THC) offers an alternative to traditional antipsychotic drugs in the long-term management of dementia with behavioral change. We present the case of an 85-year-old man with dementia with Lewy bodies with worsening aggression refractory to antipsychotic management. Multiple regimens of antipsychotics failed both in the outpatient and inpatient settings. After exhausting other options and in the setting of worsening agitation, a tincture of THC was prescribed. After starting THC tincture, the patient's behavior rapidly improved, and he was discharged home...

Abstract Historically, the multiple uses of cannabis as a medicine, food, and for recreational purposes as a psychoactive drug span several centuries. The various components of the plant (i.e., seeds, roots, leaves and flowers) have been utilized to alleviate symptoms of inflammation and pain (e.g., osteoarthritis, rheumatoid arthritis), mood disorders such as anxiety, and intestinal problems such as nausea, vomiting, abdominal pain and diarrhea. It has been established that the intestinal microbiota progresses neurological, endocrine, and immunological network effects through the gut–microbiota–brain axis, serving as a bilateral communication pathway between the central and enteric nervous systems. An expanding body of clinical evidence emphasizes that...

Abstract Background Research on cannabis-based medicinal products (CBMPs) in anxiety remains inconclusive due to a paucity of high-quality evidence. Studies indicate a bidirectional relationship between generalized anxiety disorder (GAD) and sleep disruption, but it is unclear how this affects CBMP treatment outcomes. This study aims to compare the patient-reported outcome measures (PROMs) of patients prescribed CBMPs for GAD, with and without impaired sleep. Methods Changes in PROMs were recorded from baseline to 1, 3, 6, and 12 months between those with impaired or unimpaired sleep. Multivariate logistic regression was applied to compare factors associated with a clinically significant improvement in GAD-7 at 12 months. Secondary outcomes...

Abstract Background Phytocannabinoids inhibit the aggregation and neurotoxicity of the neurotoxic Alzheimer's disease protein β amyloid (Aβ). We characterised the capacity of five proprietary medical cannabis extracts, heated and non-heated, with varying ratios of cannabidiol and Δ9-tetrahydrocannabinol and their parent carboxylated compounds to protect against lipid peroxidation and Aβ-evoked neurotoxicity in PC12 cells. Methods Neuroprotection against lipid peroxidation and Aβ1–42-induced cytotoxicity was assessed using the thiazolyl blue tetrazolium bromide (MTT) assay. Transmission electron microscopy was used to visualise phytocannabinoid effects on Aβ1–42 aggregation and fluorescence microscopy. Results Tetrahydrocannabinol (THC)/tetrahydrocannabinolic acid (THCA)-predominant cannabis extracts demonstrated the most significant overall neuroprotection against Aβ1–42-induced loss of PC12 cell...

Findings  In this systematic review and meta-analysis of 23 randomized clinical trials including 3612 participants, cannabinoids used for medical purposes in children and adolescents were associated with increased risk of adverse events, serious adverse events, and withdrawals due to adverse events compared with the control group. Meaning  The findings suggest that physicians considering cannabinoids for medical purposes in children and adolescents should weigh the risk and benefit profile of cannabinoids and available therapeutic options as well as the individual’s underlying...

Smokable cannabis forms were not legally available in this program until 2019, and five years after other forms of cannabis were available. This study assessed changes in Δ-9 tetrahydrocannabinol (THC) dispensed per patient following legalization of smokable cannabis in Florida. Materials and Methods: This quasi-experimental study used data from the Florida Department of Health Office of Medical Marijuana Use Reports on THC dispensing from April 6, 2018, through March 13, 2020. Certified medical cannabis user during the study period was included. The exposure...

Abstract Aims Cannabis use may increase the risk of self-harm, but whether legalization of cannabis is associated with changes in self-harm is unknown. We examined changes in cannabis-involvement in emergency department (ED) visits for self-harm after the liberalization of medical and legalization of non-medical cannabis in Canada. Methods This repeated cross-sectional study used health administrative data to identify all ED visits for self-harm in individuals aged ten and older between January 2010 and December 2021. We identified self-harm ED visits with a co-diagnosis of cannabis (main exposure) or alcohol (control condition) and examined changes in rates of visits over four distinct policy periods (pre-legalization, medical liberalization, non-medical...
