Give non-alcoholic beer to 100 people who don't drink beer. I don't know the number, but I would be surprised if there weren't at least 10% who reported feeling tipsy and acting in stereotypically drunk ways. I know that some psychedelic researchers use a suitable dose of niacin as the control arm. The person will experience some flushing and a faster heart rate. If they are new to psychedelics, they don't what psychedelics are supposed to feel like, and so they assume it is the real thing.
