Technically, you could get drunk from smelling vodka. Like everything else that you can sense smelling, you uptake a little bit of the vodka (mainly the alcohol, i.e. ethanol component) by smelling it.
But those quantities are really minute. You would have to take a hot vodka vapour bath and stay in there for quite some time until you realise something. Remember that the amount you need to drink to get drunk varies, but is certainly somewhere above two shots. Now imagine how long it takes for ‘two shots’ worth of vodka had to condense in your nose and mouth from breathing — almost forever.
