Will Robitussin show on an etg?

Robitussin, which contains ingredients like dextromethorphan and guaifenesin, typically does not show up on an ETG (ethyl glucuronide) test, as ETG tests are specifically designed to detect the presence of ethanol, or alcohol, in the system. However, some formulations of Robitussin may contain alcohol as an inactive ingredient, which could potentially lead to a positive result. It's important to check the specific product's label for alcohol content if you're concerned about drug testing.
