Can using an Albuterol Inhaler before blowing into the machine cause the machine to display "VIOL". I was using my inhaler before blowing and got this result 3 times in 20 minutes. I then rinsed out my mouth and blew again 35 minutes later and it said "PASS". I quit drinking almost 2 years ago, but do suffer from chronic bronchitus, hence the need for the inhaler.

You need to talk to the company who monitors it, along with your doctor. While I have not heard of this, I will not rule it out.
