Nicotinic acetylcholine receptors/nAChRs are involved in cognitive processes in the brain and in controlling muscle movement. nAChRs are not classic cannabinoid receptors but their activity is modulated by cannabinoids. Since cannabinoids have a physiological effect on nAChRs they are effectively cannabinoid receptors.
