    This = / has units of dose per body weight (g/kg) divided by concentration (g/L blood) - calculation gives values of 0.64 L/kg for men and 0.52 L/kg for women, lower than the original.

    If so it should be made much clearer that the % number is not representing anything like the true volume fraction of alcohol in the blood, but something closer to 1/10 of the volume fraction. i.e. 0.02 '%' BAC is actually 0.2% true volume i.e. 0.2 in every 100 ml of your blood is alcohol.

    One systematic analysis found that "The level of alcohol consumption that minimised harm across health outcomes was zero (95% UI 0·0–0·8) standard drinks per week". [35] Supposing the apparent beneficial effects found in observational studies are genuine, these effects are maximized at relatively low levels of consumption, ranging from 1-18 ...

    en.wikipedia.org/wiki/Alcohol_(drug)

    A blood level of 0.5% or more is commonly fatal. The oral median lethal dose (LD 50) of ethanol in rats is 5,628 mg/kg. Directly translated to human beings, this would mean that if a person who weighs 70 kg (150 lb) drank a 500 mL (17 US fl oz) glass of pure ethanol, they would theoretically have a 50% risk of dying. The highest blood alcohol ...
