Let's say you had a drink or two but don't feel you are under the influence of alcohol. However, you are arrested on suspicion of drunk driving and offered the choice of taking a breath or blood test (or, in some states, urine). Most DUI suspects choose the breath test -- a choice which could doom your chances to prove your innocence. Consider the following advice when deciding which test to take: 1. If you smoke cigarettes, you may want to pass on that Breathalyzer mouthpiece the officer is handing you. Scientific research has shown that smoking can raise the test result considerably -- enough to get you charged and convicted of drunk driving. This is 6301 Bearing Manufacturers because most breath analyzing devices will falsely report acetaldehyde as alcohol. Acetaldehyde is a compound produced in the liver in small amounts as a by-product in the metabolism of alcohol. However, scientists have found acetaldehyde concentrations in the lungs of smokers are far greater than for non-smokers. ("Origin of Breath Acetaldehyde During Ethanol Oxidation: Effect of Long-Term Cigarette Smoking", 100 Journal of Laboratory Clinical Medicine 908). Translated: because breathalyzers can't tell the difference between alcohol and acetaldehyde, cigarette smokers will have a higher blood-alcohol reading. 2. If you are a diabetic with possible low blood sugar, you should also avoid the breath test. A well-documented by-product of hypoglycemia (low blood sugar) is a state called ketoacidosis, which causes the production of acetone -- and acetone, like acetaldehyde, will be reported by the Brethalyzer as alcohol. In other words, the Breathalyzer will read significant levels of alcohol on a diabetic's breath where there may be little or none. See "Diabetes, Breath Acetone and Breathalyzer Accuracy: A Case Study", 9(1) Alcohol, Drugs and Driving (1993). To make matters worse, the reactions of a person in the early stages of a diabetic attack include dizziness, blurred vision, slurred speech, weakness, loss of coordination and confusion -- the same symptoms which the patrol officer is looking for: the clear signs of a person under the influence of alcohol. And the officer's observations are quickly followed by a failing performance on DUI field sobriety tests.
