##### The most likely reason THC induces a psychoactive response is A THC competes with neurotransmitter, preventing DAG production and activation of phospholipase D_ B. TTHC competes with AEA and 2-AG for the CBlR receptor Neurotransmitter release is not inhibited causing the synaptic signal to persist too long: C THC blocks the basal activity of the THC receptor. AEA and 2-AG can no longer induce the receptor to activate its G-protein. NT release is not inhibited; the synaptic signal persists too lo
