Arrested for drunk driving? A San Diego DUI defense law firm announces that the Breathalyzer used by law enforcement not actually measure alcohol - and thus can produce false high "blood alcohol" readings.

The Law Offices of Lawrence Taylor, Inc, San Diego, California, the most used Breathalyzer DUI cases by law enforcement today use "infrared spectroscopy". This technology includes the detection of the "methyl group" in the molecular structure of alcohol. The problem is that thousands of chemical compounds with the methyl group - some of them found on human breath. In a study with 28 subjects, for example, researchers found that the "combined expired air comprises at least 102 various organic compounds of endogenous and exogenous origin" ( "Characterization of Human exhaled air ", 15 Journal of Chromatographic Sciences 240).

If a person one of these other compounds on his breath, called "interferents" by the engineers, he will give you a false high blood alcohol test results. And if two or more such compounds on his breath, the machine and adds them to wrongly report the total as the blood-alcohol level.

So what links can be found on your breath? The San Diego DUI attorneys, diabetics with low blood sugar can have high levels of acetone - which is "seen" as alcohol Breathalyzer. And scientific studies have shown that people on diets can have blood sugar, thus reducing acetone hundreds of times higher than in normal individuals (Frank and Flores, "The probability of Acetone Interference in Breath-Alcohol Measurements", 3 Alcohol, Drugs and Driving 1). And there are many other so called "interferents" influence Breathalyzer Results

If you are a smoker, your breath test result is likely higher than expected. The compound acetaldehyde - the methyl group and thus reported by the Breathalyzer as "alcohol" - is produced in the human body as a byproduct of metabolizing ingested alcohol, and eventually goes into the lungs and breathing. Researchers have discovered that levels of acetaldehyde in the lungs can be 30 times higher in smokers than non-smokers. Result: higher BAC readings on the machine.

The San Diego DUI lawyers report that common household products like paint, glue, petrol and thinners contain the methyl group. No, you donÂ't have to drink the stuff: simply absorbing it through your skin or inhaling the vapors can lead to significant levels of the chemical in your body hours or even days, depending on the half-life of the substance. So if youÂ've painted a room or breathed fumes from a petrol station in the last day or two, do not take a Breathalyzer test.

If you stopped by the police and suspected of driving under the influence, say the San Diego DUI lawyers, you might consider a blood test Instead of submitting to a breath test.
