Can Mouthwash Beat the Breathalyzer?

With summer vacationing comes the prospect of parties with friends and a significant rise in police vigilance concerning drinking and driving.  Paul Doroshenko, an experienced Vancouver criminal defence lawyer with Acumen Law Corporation, offers a timely warning for people who think a little mouthwash will protect them from the serious consequences of blowing over the legal limit if they are stopped at a roadside check and required to submit to a Breathalyzer test.  Based on his experience handling drinking and driving cases, Mr. Doroshenko has this to say:

“Often drivers who have had as little as one drink are concerned about the odour of liquor on their breath.  This is understandable as the odour may permit a police officer to compel them to blow at the roadside.  They may be under the legal limit, but because of flaws in the tester, they may be arrested for impaired driving after blowing at the roadside.  The question is will mouthwash assist someone who has been drinking to avoid being wrongfully arrested for over .08?

Most mouthwash contains substances to create a flavour and aroma, as well as antiseptics and alcohol.  Mouthwash may mask the odour of liquor.  The problem however, is the alcohol in mouthwash.  Although it is not consumed when using mouthwash, a minuscule amount of alcohol in a driver’s mouth will often generate very high readings on most breath-testing instruments.  In our own testing mouthwash has caused elevated readings even more then 20 minutes after last use.

If you use mouthwash to disguise an odour of liquor, you may succeed in hiding the smell.  But if you are required to blow into a roadside Breathalyser, your use of mouthwash may inadvertently lead to your arrest.  So it is generally not a good practice.”
