A cross-sectional survey of cannabis use by people with MS in Oregon and Southwest Washington

Evidence supports that cannabinoids reduce self-reported spasticity and neuropathic pain in people with MS (PwMS), and legal access to cannabis for medical and recreational use continues to rise. However, there are limited data regarding patterns of cannabis use and perceived benefits of cannabis among PwMS in the US. This study describes the prevalence of cannabis use, routes of administration, perceived benefit of cannabis for MS, and characteristics associated with cannabis use and perception of benefit among a population of PwMS living in two states where cannabis is legal for both medical and recreational use.

Cross-sectional and longitudinal evaluation of cannabidiol (CBD) product use and health among people with epilepsy

Recent approval of Epidiolex® (pharmaceutical cannabidiol/CBD) for the treatment of Lennox Gastaut syndrome (LGS) and Dravet syndrome highlights a therapeutic efficacy of CBD in the treatment of epilepsy. However, a large number of patients with epilepsy elect to use alternative artisanal CBD products due to cost or access constraints. Despite widespread availability and variety of these artisanal CBD products, studies evaluating their safety or efficacy are rare, making conclusions about clinical utility uncertain. The purpose of the present study was to evaluate cross-sectional and longitudinal associations of artisanal CBD product use with quality of life, mental health, healthcare utilization, and epilepsy-specific outcomes within a large, observational cohort of people with epilepsy.

Add-on cannabidiol in patients with Dravet syndrome: Results of a long-term open-label extension trial

Add-on cannabidiol (CBD) reduced seizures associated with Dravet syndrome (DS) in two randomized, double-blind, placebo-controlled trials: GWPCARE1 Part B (NCT02091375) and GWPCARE2 (NCT02224703). Patients who completed GWPCARE1 Part A (NCT02091206) or Part B, or GWPCARE2, were enrolled in a long-term open-label extension trial, GWPCARE5 (NCT02224573). We present an interim analysis of the safety, efficacy, and patient-reported outcomes from GWPCARE5.

Long-term safety and efficacy of add-on cannabidiol in patients with Lennox–Gastaut syndrome: Results of a long-term open-label extension trial

Lennox–Gastaut syndrome (LGS) is an epileptic encephalopathy that is often treatment resistant. Efficacy and safety of add-on cannabidiol (CBD) to treat seizures associated with LGS was demonstrated in two randomized controlled trials (RCTs). Patients who completed the RCTs were invited to enroll in this long-term open-label extension (OLE) trial, GWPCARE5 (NCT02224573). We present the final analysis of safety and efficacy outcomes from GWPCARE5.

Long-term safety and efficacy of highly purified cannabidiol for treatment refractory epilepsy

To evaluate the safety, efficacy, and tolerability of highly purified cannabidiol (CBD) for the treatment of seizures in children and adults with treatment-resistant epilepsy (TRE) in an open-label, expanded access program (EAP).

Add-on cannabidiol significantly decreases seizures in 3 patients with SYNGAP1 developmental and epileptic encephalopathy

Authors: Mathieu Kuchenbuch, Gianluca D’Onofrio, Nicole Chemaly, Giulia Barcia, Théo Teng, Rima Nabbout Published in Epilepsia Open July 2020 Abstract Mutations in SYNGAP1 are associated with developmental delay, epilepsy, and autism spectrum disorder (ASD). Epilepsy is often drug-resistant in this syndrome with frequent drop attacks. In a prospective study of add-on cannabidiol (CBD), we identified…

The present status of artisanal cannabis for the treatment of epilepsy in the United States.

Authors: Dustin Sulak, Russell Saneto, Bonni Goldstein Published in Epilepsy & Behavior May 2017 Abstract The widespread patient use of artisanal cannabis preparations has preceded quality validation of cannabis use for epilepsy. Neurologists and cannabinoid specialists are increasingly in a position to monitor and guide the use of herbal cannabis in epilepsy patients. We report…
