how long does it take to get alcohol out of your system for a drug test
Actually, alcohol stays in your system up to 3-4 days after your last drink (urine screen). It will not show up using a breathalyzer after a day. If your probation officer is giving you a urine screen, again, it can show up 3-4 days later.I know, because I work as a drug and alcohol counselor. Hope this helps.ow long with alcohol depends on your individual bodily metabolism, your body weight, and how much you drink. In high school driver ed I was taught that the typical adult (and I suppose it was presumed an adult male of height 6') can metabolise 1 ounce of alchohol per hour.
