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...

Highlights •Our study reveals diverse Δ-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) dosing patterns among patients with medical conditions, drawn from longitudinal purchase data, providing insights into patient dosing. •Six trajectory groups illustrate varied THC and CBD dosing trends over time, reflecting nuanced patient behaviors and highlighting dynamic dosing trajectories. •Patients exhibit customized dosing preferences, with THC favored by patients with chronic pain and cancer and CBD preferred by those with epilepsy, indicating tailored dosing preferences. •Many patients exhibited fluctuating dosing behaviors, highlighting the necessity for personalized dosing strategies and emphasizing fluctuating dosing behaviors. •Our findings stress the...

Findings  In this cohort study of 116 076 individuals, people with cannabis use disorder had an increased risk of any HNC, as well as oral, oropharyngeal, nasopharyngeal, salivary gland, and laryngeal cancer, compared with a group of matched individuals. Meaning  The results of this study suggest that patients with cannabis-related disorder may be at an increased risk for HNC, and further studies are required to further explore the strength and potential mechanisms of this association. Abstract Importance  Cannabis is the most commonly used illicit substance...

Abstract Introduction: Cannabis policy is rapidly changing in the USA and across the globe, with 24 states legalizing cannabis for adult use and 38 states making medical cannabis available for those with qualified conditions. Building on prior evidence, we reviewed the recently published literature (from the past 5 years) focused on the treatment effects of naturally derived medical cannabis products within the pediatric population. Methods: We conducted a systematic literature review of three electronic databases using MeSH terms and free-text. A study was eligible for inclusion if it investigated the efficacy of medical cannabis for any condition, it was published in 2019 or later, and the mean...

Abstract Objective Dramatic changes in state-level cannabis laws (CL) over the past 25 years have shifted societal beliefs throughout the United States, with unknown implications for youth. In the present study, we conducted an updated systematic review and meta-analysis examining estimated effects of medical cannabis legalization (MCL) and recreational cannabis legalization (RCL) on past-month cannabis use among US youth. Method A systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, followed by a subsequent meta-analysis investigating the associations between state-level cannabis laws (ie, MCL vs non-MCL, and RCL vs non-RCL)...

This study aims to map the therapeutic benefits and adverse effects associated with the use of cannabis-based drugs in these outcomes. Methods Following Joanna Briggs Institute guidelines a scoping review was conducted. The study protocol was available in the Open Science Framework public repository. An extensive search strategy involving databases like Cochrane Library, Embase, CINAHL, Medline/PubMed, Lilacs, Google Scholar, and Open Gray for gray literature analysis was executed by a skilled librarian. The inclusion criteria were primary studies (observational...

Abstract The aim of this study is to determine factors associated with cannabis discontinuation, to assess the impact of mental health and addiction interventions on cannabis discontinuation during pregnancy and to investigate the neonatal impact of cannabis discontinuation. This is a 10-year cohort study in a tertiary hospital in Barcelona, Spain, including women with self-reported cannabis use during pregnancy. Main outcome was cannabis discontinuation based on biological sample testing. Secondary outcomes were neonatal intensive care unit (NICU) admission, preterm birth, birth weight and bottle-feeding. When cannabis use was detected during pregnancy, 32 out of 81 (38.3%) discontinued cannabis during pregnancy vs. four out of...

As the cannabis legal market grows, a critical challenge has been to make substantiated claims about the benefits and adverse health problems triggered by cannabis exposure. Despite accumulating evidence from animal studies demonstrating the role of cannabinoids on bone metabolism, there are conflicting results in clinical literature regarding their effects on bone health outcomes. We undertook a systematic review to assess the evidence for the safety of cannabis use on bone health. We searched the databases MEDLINE, EMBASE, Cochrane Library, and...

Abstract Cannabis products (CPs) and cannabis-based medicines (CBMs) are becoming increasingly available and are commonly used for pain management. The growing societal acceptance of cannabis and liberalization of cannabis laws allows patients to access CPs with minimal clinical oversight. While there is mechanistic plausibility that CPs and CBMs may be useful for pain management, the clinical trial literature is limited and does not refute or support the use of CBMs for pain management. Complicating matters, a large and growing body of observational literature shows that many people use CPs for pain management and in place of other medications. However, products and dosing regimens in...
