How can using mouthwash cool mint listerine(21.6% alcohol)as directed not drinking) cause a positive beathalyzer reading? please explain in detail.

Alcohol: Alcohol absorbs through the tissues in your mouth. Every single drug screening or treatment program i know tells every single patient this and that this type of product is not acceptable if one is being tested for alcohol. Putting listorine into your mouth is the same as drinking alcohol.The taste alone often triggers patients back into relapse.
