Ignatowska-Jankowska et al. [93] did report that the selective CB2R antagonist, AM630, prevented CBD-induced BM changes; however, CB2R has not generally been linked to feeding behaviour, and if CBD is indirectly increasing endocannabinoid tone (i.e. via AEA) [92], this might be expected to promote feeding behaviour (via indirect CB1R agonist effects) [197]. The gene discussed is CNR1; the disease is red-green color blindness.
