MAM-2201 has been recently detected in herbal products and has psychoactive and intoxicating effects in humans, suggesting that MAM-2201 alters brain function. MAM-2201 acts as an agonist of human cannabinoid receptor type 1 (CB1R) and thus to suppress neurotransmitter release. The reduction of neurotransmitter release from CB1R-containing synapses could contribute to some of the symptoms of synthetic cannabinoid intoxication including impairments in cerebellum-dependent motor coordination and motor learning.

JWH-073, a synthetic cannabinoid, is an analgesic chemical from the naphthoylindole family that acts as a neutral antagonist of CB1 cannabioid receptor and binder of CB2 cannabinoid receptor. JWH-073 is being used as a recreational drug in Spice products, and is a controlled substance in USA.
