That's an interesting fictional scenario, fuddy.
I suppose it is possible, given the diversity we see presently and historically, but I do not know of any examples close to what the scenario suggests.
Most, if not all (prove me wrong here people, I'm unsure), addictive chemicals are derived from plant materials. I'm sure psychological addiction exists within tribes who rely heavily on a certain animal species. Heck, take away beef from America and people would be in chaos (psychological addiction?).
