On: A lesser known mechanism for alcohol tolerance

[sp332]

I thought of the fumes too. Clinical studies show that alcohol doesn't absorb well through skin. e.g. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2596158/

the wrappings were subsequently soaked with 200 ml of 95% (v/v) ethanol. Although the ethanol-soaked cotton was kept covering the skin with rubber sheeting and adhesive tapes for 4–9 hours, no ethanol was measurable in the blood.

Some also probably entered the bloodstream via the colon / genitals.

Interesting. I didn't realize it was that bad at absorption.
