Are there ways to fool an alcohol test?
A. A properly administered alcohol test is difficult to fool. As long as the subject delivers an adequate deep lung breath, or gives a sufficient saliva sample, there is virtually no way to mask the alcohol. If the person claims their positive alcohol test is the result of using mouthwash just prior to being tested, give the person another alcohol test in 15 minutes. A second positive breath alcohol test after 15 minutes cannot be attributed to mouthwash or cough syrup.
