In a rat model of tonic pain, the injection of CBD into the brain’s nucleus accumbens (a major mediating center of analgesics for pain) lessened the pain response

Cannabidiol microinjection into the nucleus accumbens attenuated nociceptive behaviors in an animal model of tonic pain

In mouse neurons, the repeated use of cocaine (but not heroin) increased CB2 receptors in the dopamine neurons of the midbrain as well as the brain’s cortex & striatum (primarily the nucleus accumbens) as well as the spleen
