Can drinking large amounts of cider vinegar every day cause false pos on BAC Urine test?”
Ten tablespoons is five ounces. That five ounces of cider vinegar is equal to the amount of alcohol in, say, five beers. Except it’s vinegar, not alcohol. The “trace amount of alcohol” begin in a mere five ounces. One percent of that would be less than a third of a teaspoon, which amount would be processed and out of the system very quickly. But even in an immediate test, that 1/3 of a teaspoon is diluted by five quarts of blood in your system, 160+ times as much. I’m unsure any equipment used by parole officers could even detect that low an amount. Congratulations on the healthy drink.
