Aren't Alkylamides Just Like CBD?
No. Alkylamides directly act on CB2 receptors. Cannabidiol (CBD) has indirect activity on CB1 and CB2 receptors. CBD also has a great deal of activity on certain serotonin receptors (the 5HT1 receptors). Much of the calming activity of a CBD preparation seem to be related to the serotonin-modifying action of CBD.
Many people believe that THC stimulates the CB1 receptors, that CBD stimulates the CB2 receptors. That idea is quite wrong. THC stimulates both the CB1 and CB2 receptors directly and potently. CBD has an indirect action on both the CB1 and CB2 receptors, but much of its action has nothing to do with the endo-cannabinoid system. Selective CB2 agonists (like most alkylamides) are the closest thing to a non-psychoactive version of THC.
