I weigh 110 and I drank about 6 drinks on Thursday after that I stopped started doing heated yoga and drank a gallon of water a day will I pass a EtG on Monday if I have to do one? Additional question will kumcha make you pop positive on a EtG?

You will probably test negative for alcohol, but probably positive for dilution. That means you drank so much water that it looks like you're trying to hide alcohol in your system. Is there alcohol in Kumcha?

What happens if you fail?
