Does drinking vinegar rid the body of THC?

It will not get rid of THC in 24 hours. If you only have 24 hours then your best bet is to get something that will mask the THC from a test. You can get more information on that on the link below. Also, if you did have more time like almost a week, you could mix some vinegar with a liter of water and drink it every day up until your test. Also drink cranberry juice here and there. But to say it again, vinegar will not get rid of THC in 24 hours...you need something to cover the THC from showing up on your test.
