1. A cell-based assay for quantifying the potency and/or efficacy of one or more cannabinoids and/or terpenoids present in a test sample, wherein the assay comprises:
(a) one or more human cell types derived from one or more different human tissues, wherein:
(i) the one or more human cell types have either wild-type CB1 and/or CB2, CB1 knockouts, CB2 knockouts, or CB1/CB2 knockouts, and
(ii) the one or more human cell types are genetically engineered to express a G protein selected from a promiscuous G alpha protein that converts G protein-coupled receptor (GPCR) signaling to a positive calcium release and/or other changes; and
(b) one or more reagents for quantifying the potency and/or efficacy of the one or more cannabinoids and/or terpenoids present in the test sample, wherein the quantifying is based on measuring GPCR-dependent changes in the one or more human cell types after the test sample is contacted with the one or more human cell types compared with a calibration control.
