"People spend years at university trying to figure out this stuff," he said. "Some neurotransmitters are inhibitory; they limit cell behavior. So if a cannabinoid inhibits their release, it removes their inhibitory effect, which produces an excitatory effect. Cannabinoids also inhibit release of excitatory neurotransmitters. When you remove the excitatory effect, you end up with an inhibitory effect. Hence, cannabinoids can produce a mixed excitant and depressant effect."

In short, "Balance".
