"A French American scientist has invented a new alcohol spray that instantly intoxicates the user. However, the effects are nearly as brief, wearing off in a matter of moments."
"Reportedly, not only does the sensation of being drunk wear off almost immediately but the user would also supposedly be able to pass a breathalyzer test, verifying that they are no longer under the influence of alcohol."
I have no idea why someone would want to be instantly drunk for a few seconds. I do wonder if it causes someone to have a nystagmus.
