What Can Cause a False Positive Alcohol Test?

Answer

Alcohol can be tested in the breath, blood, saliva, or urine. Since blood tests are invasive procedures, and urine tests are often an inaccurate measure of a person's current inebriation level, the most commonly used test is a breath test. However, there are several consumables that are known to cause false positive results on a standard breathalyzer test. Mouthwash, soda, certain asthma inhalants, and OTC decongestants are all items that have caused a false positive result on an alcohol test.
