The animals, none of which had prior exposure …
Large Multinational Trial Underway to Determine if CBD May Improve Behavioral Issues in People With Tuberous Sclerosis
A large international trial is underway to determine whether CBD can help improve behavioral symptoms in people with tuberous sclerosis complex (TSC), a condition that affects about 90% of patients with a group of neuropsychiatric symptoms known as TAND. The study, called EpiCom, is a phase 3b/4 open-label trial taking place at around 20 sites …
Study: Psilocybin Reduces Depression in Veterans With Severe Treatment-Resistant Depression, With Some Effects Lasting a Year
A new pilot study suggests that a single dose of psilocybin may significantly reduce depression symptoms in military veterans with severe treatment-resistant depression (TRD), with effects lasting up to a year in some patients. Researchers from Ohio State University and Stanford University School of Medicine tracked 15 veterans who received a 25 mg dose of …
Study: Oral THC More Effective Than CBD or THC+CBD for Acute Inflammatory Pain

Study: Cannabidivarinic Acid (CBDVA) Found to Deter Aphids, Offering Natural Pest Control Option
Researchers from Colorado State University, Cornell University and the USDA have found that a rare cannabinoid called cannabidivarinic acid (CBDVA) significantly reduces aphid populations, suggesting it could serve as a natural insecticide for hemp and cannabis crops. In the study, published in the Journal of Cannabis Research and archived by the National Library of Medicine, …
Study: CBD May Curb Methamphetamine Relapse by Targeting Brain’s Dopamine Receptors
A new study finds that cannabidiol (CBD) may help reduce relapse behaviors in methamphetamine addiction by interacting with dopamine receptors in a key brain region linked to memory and emotion. Researchers from the Iranian Academy of Medical Sciences and three Iranian universities found that CBD’s impact on methamphetamine-seeking behavior is partly mediated by D2-like dopamine …
