Date rape drug-sensing fingernail polish?

As I understand it, the idea is that the drugger then “helps her out of the bar to her car”, while of course hauling her to his car instead.

So, perhaps what this magic fingernail polish actually does, is tell you if your drink has any alcohol in it.

Date rape drugs are largely an urban myth, they do EXIST but the idea that women are being commonly drugged and raped by them is the myth.

And while I am unsure about the benzos used, GHB almost always comes in the sodium form and is incredibly salty like GRAMS of salt per dose. 2-4 grams is used as a dose, would anyone fail to notice grams of salt in their drink except maybe a bloody mary?

I guess it’s not technically completely impossible. Enforcement people have quick test kits that are engineered to indicate the presence of this or that - and false positives are possible.

I just doubt that this is more than a concept - that is, I doubt the actual chemistry has been worked out in any detail at all.
