A device which installed recently at a bar in Bristol, UK, which allows users to sniff the alcoholic beverage of their choice can do similar damage to the nasal passages as heavy cocaine use, British researchers warn.
"There would be some irritant effect because alcohol is a defatting agent and if it overloaded cells and damaged them there could be some pathology." said Leeds University's Alastair Hay, a top toxicologist.
The vapourised alcohol effects the body in such a way that somebody could easily pass a breathalyser test but be too drunk to drive a car. Another side effect could be brain damage, but this is seen as an extreme reaction.
