If I drink a lot of water and try to flush my system out will I pass the 80 hr alcohol test?test?

It depends on when you last drank and how much you drank, but if you drank say 2 days before your test and wanted to pass drink as much water as possible, if the test comes up positive the person giving the test whether it's a PO or a drug counselor or whoever it is, there are many excuses for you to have alcohol in your system that work because the 80 hour tests can test positive for alcohol even if you have been around household cleaning products, used large amounts of hand sanitizer, hairspray, cosmetics and pretty much almost anything that is mainly alcohol based.
