Researchers confirmed that cannabis universally increases appetite regardless of your body type, gender, or how recently you ate—knowledge that could help develop better treatments for patients who can’t eat due to illness. Researchers at the University of Colorado Anschutz Medical Campus analyzed cannabis usage, brain scans, and cognitive test results for over 26,000 adults ages 40-77 using UK Biobank data. Moderate lifetime cannabis users showed larger volumes in brain regions rich in CB1 receptors—areas involved in memory, information processing, and emotion regulation.
