Can phenol make a person fail a breahilizer?

Phenol itself is not typically a substance that would cause a person to fail a breathalyzer test for alcohol. Breathalyzer devices are designed to detect ethanol, the type of alcohol found in Alcoholic Beverages. However, certain products containing phenol, like some mouthwashes or cough syrups, could potentially affect breathalyzer readings if they contain alcohol. It's always best to avoid consuming any products with alcohol if you plan to drive.
