Illinois defense attorney, Illinois criminal lawyerThe breathalyzer as we know it today was born in 1954 by a man named Robert Borkenstein and has undergone little alteration since it’s introduction. An estimated 86% of the adult population of the United States claims they have consumed alcoholic beverages at least one time in their life, many of which went on to drive home. Breathalyzers use technology to detect the amount of alcohol on the breath of these drivers, which results in DUI allegations. This form of sobriety test has many pitfalls, and for this reason, researchers, inventors, and scientists all over the world scramble to create the next alcohol detection device.

The Current Device

The current tool is a guideline and no means is it perfected to 100% accuracy. Everyday items such as mouthwash and cough syrup are known to register a false positive in some machines. By breathing into the device, the device is estimating the amount of alcohol on your breath.

No two people are exactly alike, not even identical twins. Yet, almost everything produced today is based on results for the “average person”. As everyone is different, there logically really cannot be an “average” for some things. Take for example, a breathalyzer. A breathalyzer determines the Blood Alcohol Concentration (BAC) in your system when you breathe into it. Police officers today use this as a ready tool for charging an individual with  driving under the influence (DUI).

The basis of the breathalyzer calculations are on the average person, the one that does not exist. Let us also take into account that a breathalyzer measures BAC only indirectly, via the expiration of breath from the lungs, rather than directly from the blood. This alone gives a wide margin of error. While this is something that is incessantly redeveloped and argued, the current measuring system is inadequate to say the least.
