Are there any substances that can interfere with breathalyzer readings?

Yes, certain substances can indeed interfere with breathalyzer readings, leading to inaccurate results. Breathalyzers are designed to detect alcohol in the breath, but other substances can produce similar chemical reactions, affecting the reliability of the readings. One common example is mouthwash, which often contains a high concentration of alcohol and can result in elevated readings if testing occurs soon after use. Additionally, certain foods, such as those containing fermentable carbohydrates, can potentially release alcohol when metabolized, thus affecting breathalyzer results. Medications, particularly those containing alcohol, can also produce skewed readings. For instance, some cough syrups and liquid cold medications have significant alcohol content, and consuming these can yield false positives. It is worth noting that some breathalyzers may have calibration and sensitivity levels that help mitigate these interferences, but the precision can vary across different models. Other factors, like the user's physiological characteristics and the test environment, can also play a role in the accuracy of the readings. For those needing reliable breath alcohol readings, it is advisable to refrain from consuming any substances that could potentially interact with the device before taking a test.
