D. was associated with an average decline IQ score of about 8 points
Generally speaking, how do synthetic cannabinoids differ from the phytocannabinoid, THC? A. Synthetic cannabinoids are typically much more potent than THC B. Synthetic cannabinoids are full agonists at CB1 receptors, whereas THC is a partial CB1 receptor agonist C. Synthetic cannabinoids are able to produce a maximum functional response while occupying relatively few receptors, in comparison to THC's ability to do so D. Whereas THC metabolites exhibit reduced affinity for CB1 receptors, many of the metabolites of synthetic cannabinoids retain their high affinity for CB1 receptors E. All of the above represent ways in which synthetic cannabinoids differ from THC.
E. All of the above represent ways in which synthetic cannabinoids differ from THC.
