No. Usually alcohol will be out of your system within 24 hrs depending what you were drinking and how much. But no more than 32 hrs.
Can Alcohol Be Detected In Your Urine Sample After 1 Week?
No it can only be detected in an EtG test 3-5 days after use and the traditional methods can only test back 24 hours....
Not likely , it takes about 10 hours for 1 % of alcohol to dissolve in your system.
I think people are misunderstanding your question.. If you give a dirty urine for alcohol, if the urine sample is kept properly, yes the urine will still be dirty for alcohol after a week (if retesting is necessary)
