Breathalyzers measure mouth alcohol levels and presume that the level emanates from the lungs. Thus, according to
DUI Blog a study conducted with Listerine mouthwash on a breath machine reported in an article entitled "Field Sobriety Testing: Intoxilyzers and Listerine Antiseptic", published in the July 1985 issue of The Police Chief, found after study participants swished 20 milliliters of Listerine mouthwash for 30 seconds in accordance with directions on the label, they blew an average reading of .43% blood-alcohol concentration - near lethal proportions. After three minutes the concentration was still.20%, well above the legal limit. After five minutes participants were still blowing an average of .11%. As for spraying Binaca:
In another study, reported in 8(22) Drinking/Driving Law Letter 1, a scientist tested the effects of Binaca breath spray on an Intoxilyzer 5000. He performed 23 tests with subjects who sprayed their throats, and obtained readings as high as .81% — far beyond lethal levels. The scientist also noted that the effects of the spray did not fall below detectable levels until after 18 minutes.
Don’t spray and drive.
