Neuroscience research on cannabis and anxiety

Overview

Neuroscientists have identified specific brain circuits that link cannabis use to increased anxiety, panic, and paranoia. Research published in Nature Communications utilized animal models to observe how cannabinoids interact with fear responses.

Studies conducted by researchers from Western University and Northwestern University found that cannabinoids activate a specific group of cells known as somatostatin neurons in the central amygdala. This activation appears to weaken the signals that normally regulate these cells, effectively removing a biological ‘brake’ on fear responses and leading to heightened anxiety when subjects are exposed to stressful stimuli.

    Neuroscientists identify brain circuits linking cannabis to anxiety

    Researchers have identified that cannabinoids can trigger anxiety and paranoia by activating somatostatin neurons in the central amygdala, especially when combined with stressful environments.

    Researchers identify nose-to-brain circuit linking breathing and anxiety

    New research identifies a nose-to-brain circuit linking breathing patterns to anxiety, while studies confirm deep breathing helps manage aggression by activating the parasympathetic nervous system.
