I know that EtG tests do not measure alcohol level, but the level of alcohol metabolites in the blood. They can stay in your blood for up to 7 days. What can I do to fool this test?

The best way to fool the test is to simply not consume alcohol... since obviously you're not supposed to be doing it for some reason.

Realistically, I'm not a doctor, but I know there is no way to "fool" this test.

Mayo, eat a lot of mayo, it hides the effect of the drugs
