A mindfulness-based intervention to reduce altered brain reward function in cannabis use disorder: a double-blind, active and passive, randomised controlled fMRI trial.

Psychopharmacology May 7, 2026 Emillie Beyer, Martine Skumlien, Govinda Poudel et al.

Cannabis Use Disorder (CUD) affects ~ 50 million individuals worldwide and is associated with alterations in brain reward pathways. Mindfulness-based interventions (MBIs) show promise in reducing substance use and aberrant brain function in substance use disorders (SUD), but the effects on CUD or brain reward function have not been investigated. To examine whether a 2-week MBI vs. active...

Daily Cannabidiol Administration for 10 Weeks Modulates Hippocampal and Amygdalar Resting-State Functional Connectivity in Cannabis Users: A Functional Magnetic Resonance Imaging Open-Label Clinical Trial

Cannabis and Cannabinoid Research July 26, 2023 Valentina Lorenzetti, Eugene McTavish, Samantha J Broyd et al.

Introduction: Cannabis use is associated with brain functional changes in regions implicated in prominent neuroscientific theories of addiction. Emerging evidence suggests that cannabidiol (CBD) is neuroprotective and may reverse structural brain changes associated with prolonged heavy cannabis use. In this study, we examine how an ∼10-week exposure of CBD in cannabis users affected...

Mismatch Negativity and P50 Sensory Gating in Abstinent Former Cannabis Users

Journal of Neural Transplantation and Plasticity February 25, 2016 Samantha J Broyd, L. Greenwood, Hendrika H Van Hell et al.

Prolonged heavy exposure to cannabis is associated with impaired cognition and brain functional and structural alterations. We recently reported attenuated mismatch negativity (MMN) and altered P50 sensory gating in chronic cannabis users. This study investigated the extent of brain functional recovery (indexed by MMN and P50) in chronic users after cessation of use. Eighteen ex-users (median...
