Will you pass a ua if drank 1 beer 4 hours earlier?

The answer to this question depends on several factors, including your gender, weight, metabolism, and hydration level. Generally speaking, one beer consumed four hours earlier is unlikely to be detectable in a urine test. However, if you are a small person, have a slow metabolism, or are dehydrated, the alcohol may still be present in your urine. To ensure that you pass a urine test, it is best to avoid alcohol for at least 24 hours before the test.
