There is a really fun way to ingest alcohol via breathing. Get a styro coffee cup, and pour in about shots worth of your favorite liquor. The, get the lid ready and drop a small peice of dry ice down into the alcohol and slam on the lid. It creates lots of alcohol mist that is ready for breathing consumption. I only did it once. mostly cause it has no point. We went through numerous shots and never got drunk. You do have to pace yourself though. It's lots o' CO2 you are inhaling.
People apparently do this all the time, so inhaling alcohol can't be that bad? I smell wives tales.
