Can you pass a ETG UA in 36 hours after taking a detox?

Probably. No guarantees. ETG tests are too unreliable to say for sure. You may not pass if you have used any products containing alcohol, such as hand sanitizer or mouthwash. There is a serious problem of false positives for people who have not consumed any alcoholic beverage, about which the US federal government has warned those who perform EtG tests.
