I was all set to correct you, as soon as I refreshed my memory with Google's aid. But alas, I am just plain wrong. You are right both regarding nicotine and cannabinoid receptors. If I could, I would punch my memory in the face.

Agonism at the nicotine receptors induces dopamine release, but so does antagonism of the acetylcholine m1 receptors. So perhaps a combined nicotinergic agonist + M1 antagonist would have antidepressant like effects.
