Colognes And Breathalyzers: A Dangerous Mix?

It is possible for cologne to affect the outcome of a breathalyzer test. Breathalyzers are used to determine the blood alcohol content (BAC) in an individual's breath. However, they can also identify other methyl-based compounds and mistake them for alcohol. Products containing alcohol, such as cologne, can cause a breathalyzer to detect the alcohol concentration and report a false positive. This is because the breathalyzer assumes that the breath sample provided comes directly from deep lung air and multiplies the presence of any methyl-based compounds by 2100, resulting in an inflated alcohol level reading.

Yes, cologne can cause false positives on a breathalyzer test

Yes, cologne can cause false positives on a breathalyser test. This is because colognes and perfumes often contain alcohol, which is what breathalyser tests are designed to detect. The breathalyser test works by measuring the quantity of ethanol in your breath, and as such, any alcohol-based product can cause a false positive. This includes cologne, perfume, mouthwash, toothpaste, hand sanitiser, bleach, aftershave, and even bug repellent.

The impact of cologne on a breathalyser test is significant enough that Indian airlines considered banning perfume and cologne for crew members to reduce the risk of false positives on breathalyser tests. This was to ensure that crew members did not inadvertently test positive due to alcohol in their perfume or cologne, which could be mistaken for alcohol consumption.

It is important to note that breathalyser tests can also be affected by other factors, such as food, medication, and environmental factors. For example, consuming certain foods and drinks, such as fruit, hot sauce, energy drinks, fermented sodas, and protein bars, can also trigger a false positive. Additionally, certain medications, including asthma inhalers and over-the-counter drugs like Nyquil, can leave residual alcohol-like compounds in the mouth, leading to inaccurate results.

Environmental factors, such as exposure to chemical fumes, paints, or adhesives in enclosed spaces, can also impact the accuracy of breathalyser tests. Therefore, it is crucial for individuals to be aware of their surroundings and any potential sources of alcohol or alcohol-like compounds that could influence the outcome of a breathalyser test.

Other products that can cause false positives include toothpaste, hand sanitiser, and bleach

It is important to be aware that certain products can cause a false positive on a breathalyser test. These include:

Toothpaste

Some types of toothpaste can contain small amounts of alcohol, which can be detected by a breathalyser and cause a false positive result.

Hand Sanitiser

Hand sanitiser is another product that often contains alcohol, typically in the form of isopropanol (rubbing alcohol) or ethanol. Using hand sanitiser before handling a breathalyser test can lead to a false positive result due to the vapour transfer from the hands to the breathalyser. This is especially true if the sanitiser is not allowed to dry properly before handling the test.

Bleach

Bleach is a substance that can affect breathalyser results. While it is unlikely that someone would come into direct contact with bleach, it is possible that trace amounts could be present on the skin or in the environment, potentially influencing the accuracy of the test.

In addition to these products, other substances such as aftershave, oral rinse products, fragrances, cologne, and insect spray can also lead to false positives due to their alcohol content. It is important for individuals to be aware of these potential sources of error and consult with a legal professional if they believe their breathalyser results were inaccurate.

Mouthwash and breath sprays can also cause false positives, as they often contain alcohol

Mouthwash and breath sprays are often used to improve oral hygiene and freshen breath. However, many of these products contain significant amounts of alcohol, which can lead to false positives on breathalyser tests. For example, Listerine mouthwash contains 27% alcohol. If used shortly before a breathalyser test, these products can cause the device to detect alcohol and report a false positive result. This is because breathalysers capture a sample of the air exhaled and presume that it represents "Alveolar" (deep lung) air. They identify any methyl-based chemical on the breath and multiply it by 2100, resulting in an overstated presumed alcohol level.

To avoid this issue, it is recommended that individuals refrain from using mouthwash or breath sprays before taking a breathalyser test. Police officers are also advised to monitor drivers for a minimum of 15 minutes before conducting a breathalyser test to ensure that any foreign substances or compounds have cleared from the mouth. However, not all officers adhere to this rule, and some compounds may not dissipate from the mouth within this timeframe.

It is important to note that other products, such as toothpaste, hand sanitiser, bleach, aftershave, and even bug repellent, can also contain alcohol and potentially lead to false positives on breathalyser tests. Therefore, individuals should be cautious when using any product that may contain alcohol before submitting to a breathalyser test.

In addition to mouthwash and breath sprays, certain medications, environmental factors, and medical conditions can also affect breathalyser results. For example, asthma inhalers and over-the-counter medications like Nyquil or Vicks products can leave residual alcohol-like compounds in the mouth, leading to false positives. Fermented foods such as kimchi, sauerkraut, and soy sauce can also produce trace amounts of alcohol in the mouth, which may be detected by a breathalyser.

Medications, such as asthma inhalers, can leave alcohol-like compounds in the mouth

Inhalers containing albuterol, salmeterol, and budesonide are often used to relieve asthma symptoms. However, these medications can leave residual alcohol-like compounds in the mouth, which a breathalyser might mistakenly detect as alcohol. If you have used your inhaler shortly before taking a breathalyser test, it could skew your results.

Other medications, such as over-the-counter drugs like Nyquil or certain Vicks products, also contain alcohol. Taking these medications before a breathalyser test can lead to a false positive. Even alcohol-containing cough drops or toothache gels like Anbesol can produce trace amounts of substances that can interfere with breathalyser readings.

It is important to note that while asthma inhalers may not have a direct interaction with alcohol, liver problems have been reported in people taking certain asthma medications, especially when combined with alcohol. Therefore, it is always best to consult your doctor about drinking alcohol while taking any medication, including asthma inhalers.

Additionally, while alcohol and albuterol do not present any known concerns, alcohol and asthma can be a dangerous combination. Some types of alcohol, such as wine, contain histamines and sulfites, which can trigger allergic reactions and exacerbate asthma symptoms. Excessive alcohol intake can also increase the risk of hospitalisation and other health complications for people with asthma.

Environmental factors, such as exposure to paint fumes, can also affect breathalyser results

Environmental factors, such as exposure to paint fumes, can indeed affect breathalyser results. Paint is made up of a pigment dissolved in a liquid solvent, and often includes other additives. Paints can contain harmful chemicals such as volatile organic compounds (VOCs), which are released into the air as gases. Exposure to VOCs can have short and long-term health effects, including irritation to the eyes, nose, and throat, as well as dizziness and light-headedness.

In some cases, exposure to paint fumes in poorly ventilated areas can affect breathalyser results, causing false readings. This is because paint fumes contain alcohol-like compounds that a breathalyser might mistakenly detect as alcohol. The impact of paint fumes on breathalyser results is particularly relevant for those who work with paint, such as painters and construction workers.

It is important to note that the effects of paint fumes on breathalyser results may be influenced by various factors, including the type of paint, the level of ventilation, and individual health conditions. To minimise the potential impact on breathalyser results, it is recommended to work in a well-ventilated area and take breaks to get fresh air. Additionally, wearing a respirator or mask can help reduce the inhalation of paint fumes.

Overall, while exposure to paint fumes can affect breathalyser results, it is important to be aware of other factors that may contribute to false readings, such as the presence of other environmental chemicals or individual health conditions.
