GO:0038171

The series of molecular signals generated as a consequence of a cannabinoid binding to a cell surface receptor. The pathway proceeds with the receptor transmitting the signal to a heterotrimeric G-protein complex and ends with regulation of a downstream cellular process, e.g. transcription. Cannabinoids are a class of diverse chemical compounds that include the endocannabinoids and the phytocannabinoids. [GOC:bf, GOC:jc, GOC:signaling, Wikipedia:Cannabinoid]
