Cannabinoidergic, or cannabinergic, means "working on the endocannabinoid neurotransmitters". As with terms such as dopaminergic and serotonergic, related proteins and cellular components involved in endocannabinoid signaling, such as the cannabinoid (CB<sub>1</sub>) receptor, as well as exogenous compounds, such as phytocannabinoids or other cannabinoids which modulate the activity of endocannabinoid system, can be described as cannabinoidergic.
