Q&A - Mouthwash & Roadside Alcohol Testing
Yesterday, over a 6 hr. span, my husband had consumed 4 cans of beer, and 2 5oz glasses of 11.5% white wine, with lots of ice. My husband is 165 lbs. He had an 8 hr. sleep. He woke up in the morning, did his usual coffee, shower, shave, etc. ( 1hr. total) he then brushed his teeth, and gargled with his mouthwash. He then left for work, and 10 minutes later, there was a roadblock at 7:30 a.m. The officer smelled alcohol. He was given a breathalizer, and it blew WARN. He was given a 3 day IRP, and vehicle impounded for 3 days.
Now my question for you is this: He had 6 drinks over 6 hours, and there was a total of 9 hours lapping before the test. Should the alcohol not have been out of his system? After thinking about it, I thought maybe it was the mouthwash.
I did some research, and it says that mouthwash can elavate and increase your mouth alcohol level. Our mouthwash is 26% alcohol. (SCOPE OUTLAST 5x longer was the brand) Is it possible that 10 minutes after rinsing with mouthwash could it have caused mouth alcohol, and therefore gave a false reading? And if so, what can we do about it?
