Drug of choice

There are only two kinds of people in the world: those remaining indigenous who are still living an authentic human existence, hunter-gatherers, and the rest of us, agriculturalists. (Note that global industrial civilization, for all of its layers of mediation, for all of its mechanical separation and distortion, is an agriculturalist lifestyle, and ultimately grounded in the dirt of domestication.)

The recreational drug of choice in hunter-gatherer communities is usually some form of hallucinogen.  Hallucinogenic compounds are rarely addictive because they typically don’t operate on the dopamine-based reward circuits of the brain. By stark contrast, the drug of choice for agriculturalists is invariably an addictive agent that directly targets the reward circuits: almost always a pain-reducing soporific such as alcohol or opium, but occasionally a behavior-increasing dopaminergic substance such as cocaine or amphetamine.

Two things here:

First, why is it hunter-gatherers tend to prefer perception-expanding agents over feel-good chemicals?

Second, what is it about a domestication-based lifestyle that lends itself to drugs that target the brain’s reward circuits? And why is it that the drug of choice for agriculturalists is usually an experience-blunting analgesic agent?
