Does vodka evaporate

Not in the conventional sense. However, alcohol is chemically similar to ether, and inhaling the concentrated fumes can cause stupor, unconsciousness and a nasty hangover afterward. We suggest foregoing it in favor of a pint or two.

Inhalants in general are dangerous because they often cause nausea in addition to loss of consciousness. That can result in suffocation from inhaling your own vomitus.
