That's an interesting point. But maybe there are some compounds that can induce a state that fools people who've never tried psychoactive compounds? I've heard of studies using dehydrated water as a placebo for alcohol as it induces some of the same effects:
Like ethanol, heavy water temporarily changes the relative density of cupula relative to the endolymph in the vestibular organ, causing positional nystagmus, illusions of bodily rotations, dizziness, and nausea. However, the direction of nystagmus is in the opposite direction of ethanol, since it is denser than water, not lighter.
Angående sportsdelen: Anders Nedergaard har et spændende afsnit med Ask Vest Christiansen, lektor ved Aarhus Universitet, hvor de netop snakker om transkvinder i idræt
