Discovery sheds new light on marijuana’s Anxiety Relief effects:

An international group led by Vanderbilt University researchers has found Cannabinoid Receptors, through which marijuana exerts its effects, in a key emotional hub in the brain involved in regulating anxiety and the flight-or-fight response.

This is the first time cannabinoid receptors have been identified in the central nucleus of the amygdala in a mouse model, they report in the current issue of the journal Neuron.
