Arrested for drunk driving? A San Diego firm of DUI defense attorneys reports that breathalyzers utilized by law enforcement don't really live alcohol -- and therefore may produce falsely high "blood alcohol" readings.
In keeping with the the Law Offices of Lawrence Taylor, Inc., in San Diego, California, most breathalyzers utilized in DUI cases by law enforcement nowadays use "infrared spectroscopy". This technology involves detection of the "methyl group" within the molecular structure of alcohol. The problem is that there are thousands of chemical compounds containing the methyl cluster -- a number of them found on the human breath. In one study involving twenty eight subjects, for instance, researchers found that the "combined expired air contains a minimum of 102 varied organic compounds of endogenous and exogenous origin" ("Characterization of Human Expired Air", 15 Journal of Chromatographic Sciences 240).

If somebody has any of those different compounds on his breath, known as "interferents" through the engineers, he can get a falsely high blood-alcohol take a look at result. And if there are 2 or a lot of such compounds on his breath, the machine will add them up and falsely report the entire as a result of the blood- alcohol level.
So what compounds can be found on your breath? According to the San Diego DUI attorneys, diabetics with low blood sugar can have high levels of acetone -- that is "seen" as alcohol by Breathalyzers. And scientific studies have found that people on diets will have reduced blood-sugar levels, inflicting acetone lots of times more than found in ancient individuals (Frank and Flores, "The Likelihood of Acetone Interference in Breath Alcohol Measurements", three Alcohol, Medication and Driving one). And there is certainly numerous completely different therefore-referred to as "interferents" affecting breathalyzer results
If you are a smoker, your breathalyzer result is probably to be on prime of expected. The compound acetaldehyde -- containing the methyl group and thus reported by the Breathalyzer as "alcohol" -- is created in the human body as a by-product in metabolizing consumed alcohol, and eventually passes into the lungs and breath. Researchers have discovered that levels of acetaldehyde at intervals the lungs can be thirty times higher in smokers than in non-smokers. Result: higher BAC readings on the machine.
The San Diego DUI lawyers report that common household product, like paint, glue, gasoline, and thinners also contain the methyl group. No, you don’t must drink the things: merely absorbing it through your skin or inhaling the fumes can result in important levels of the chemical in your body for hours or even days, relying upon the "half- life" of the compound. Thus if you’ve painted a area or breathed in fumes at a gas station within the last day or two, do not take a breathalyzer test.
If you're stopped through the police and suspected of drunk driving, say the San Diego DUI lawyers, you'll assume concerning a blood have a look at rather than submitting to a breathalyzer. But can you actually do it when you are in high situation?
