Can mouthwash or treatments increase my BAC on a breath test?

Mouthwash, if it is alcohol-based, such as Listerine or Cepacol, can increase your BAC level because it can cause residual alcohol to remain in your mouth and then be blown into the machine. That alcohol is thought to evaporate in about 15 to 20 minutes. That is the reason why, any time a breath test is given, particularly at the side of the road when a person is first detained, it's very important that the police officers wait 15 to 20 minutes before administering a breath test.
