Proponents of CBD claim it's helpful in treating a range of substance use disorders, despite there being limited evidence to support this. It's believed to work like this: CBD binds to receptors throughout the brain and body to help balance the endocannabinoid system (ECS), which in turn steadies important bodily functions like sleep and mood. And by stimulating the brain’s serotonin and dopamine receptors, CBD also reduces drug-seeking behavior making it less likely people will pursue addictive substances.
