It's funny, because over the weekend, I asked a man in his forties (who works for a top laboratory, Ross & Abbott Labs) and his son (engaged, daughter) if they've ever heard of cannabinoid receptors in their brain. The older man said he knew there were receptors but didn't know they were called Cannabinoid receptors and his son said, "No, way. That would mean, like, God made us to smoke pot."

It was on successive nights.
