What Besides Alcohol Can Set Off a Breathalyzer?
Breathalyzers, while incredibly useful tools for law enforcement and workplace safety, aren't foolproof. They detect alcohol based on the presence of ethanol, but several other substances can trigger a false positive, leading to inaccurate readings. Understanding these potential interferents is crucial for both individuals and professionals who rely on breathalyzer results.
This article explores various substances that can cause a breathalyzer to register a positive result even in the absence of alcohol consumption. We'll also delve into the science behind these false positives and discuss the importance of corroborating breathalyzer results with additional testing.
What Substances Can Cause False Positives on a Breathalyzer?
Several substances can interfere with breathalyzer readings, leading to inaccurate results. These include:
-
Acetone: This is a common chemical found in some nail polish removers, cleaning products, and even in the body as a byproduct of metabolism. High levels of acetone in the breath, such as from someone with uncontrolled diabetes, can produce a false positive.
-
Certain Mouthwashes: Some mouthwashes contain alcohol, and even alcohol-free varieties might contain other compounds that can affect the breathalyzer's sensors. Always disclose recent mouthwash use to law enforcement or testing personnel.
-
Some Medications: Certain medications, especially those containing alcohol or alcohol-related compounds, can interfere with breathalyzer readings. Always inform healthcare professionals and employers of any medications you're taking if breathalyzer testing is involved.
-
Sour Foods: Foods high in sugar or acids, such as fermented foods (like kimchi or sauerkraut), can momentarily increase the amount of certain volatile organic compounds in your breath. While generally not high enough to produce a significant false positive, it can sometimes affect the initial reading slightly.
-
Diabetes: As mentioned earlier, uncontrolled diabetes can lead to high levels of acetone in the breath, triggering a false positive.
-
Industrial Chemicals: Exposure to industrial chemicals containing alcohol-like compounds can also lead to false positives.
-
Certain Food Products: Foods containing natural alcohols, though often in minimal amounts, may cause a slight elevation in readings. Certain fruits, for example, contain small amounts of alcohol as a natural byproduct of fermentation.
How Accurate are Breathalyzers?
Breathalyzers are generally reliable instruments, but their accuracy can be affected by various factors. The device itself needs to be properly calibrated and maintained, and the testing procedure must be followed precisely. Environmental factors, such as temperature and humidity, can also play a role. Furthermore, individual physiological factors, like the presence of the substances listed above, can influence the accuracy of the test. Therefore, it is critical to acknowledge that a breathalyzer result should not be taken as the sole determinant of intoxication.
What if My Breathalyzer Test Shows a False Positive?
If you believe you've received a false positive on a breathalyzer test, it is crucial to request further testing, such as a blood test. Blood tests are more accurate and less susceptible to interference from other substances. Furthermore, always clearly state any potential sources of interference, such as medication or recent exposure to chemicals, to the person administering the test.
Can a Breathalyzer Detect Other Substances?
No, breathalyzers are specifically designed to detect ethanol (the type of alcohol found in alcoholic beverages). They do not detect other drugs or substances.
