At 0.5 percent can alcohol free beer be detected in a urine test? Also, how many of these beers at one time can possibly be detected in a urine test?

I'm pretty sure most cough syrups and mouthwashes contain at least that much alcohol, if not more. If those don't show up on a drug screen, then I doubt the beer would.

Just to be safe, why not limit the number you drink, or not drink it at all.
