Understanding Medical Conditions that Can Cause False Positive Results on Breath Tests as a DUI Defense Strategy in Florida
When facing a DUI (Driving Under the Influence) charge in Florida, it is crucial to explore all possible defense strategies. One potential avenue is to challenge the reliability of breath test results. While breath tests are commonly used to measure blood alcohol concentration (BAC), they are not infallible and can produce false positive readings under certain circumstances. This article will explore medical conditions that can cause false positive results on breath tests and discuss the stages of a DUI criminal case in Florida.
Medical Conditions and False Positive Breath Test Results
Gastrointestinal Conditions: Medical conditions affecting the gastrointestinal system, such as acid reflux, gastroesophageal reflux disease (GERD), or heartburn, can lead to inaccurate breath test results. These conditions may cause alcohol vapors from the stomach to be released into the mouth, resulting in a higher BAC reading on the breath test than what is actually present in the bloodstream. The presence of alcohol vapors in the mouth can create a false perception of intoxication.
Diabetes: Individuals with diabetes may have a higher concentration of acetone in their breath due to the breakdown of fats instead of glucose. Breath testing devices can sometimes mistake acetone for alcohol, leading to a false positive result. Acetone is a ketone body that can be detected by breathalyzer devices, potentially skewing the BAC reading and inaccurately indicating intoxication. It's important to note that individuals with diabetes should always disclose their condition to law enforcement during a DUI arrest.
Ketogenic Diets: Following a ketogenic diet, which is high in fat and low in carbohydrates, can also cause the production of acetone in the breath. As mentioned earlier, breath test devices may incorrectly interpret this acetone as alcohol, resulting in an erroneous BAC reading. It is important to note that this does not mean that individuals on a ketogenic diet are intoxicated; rather, it highlights the potential for false positive breath test results. Individuals on ketogenic diets should inform law enforcement of their dietary restrictions during a DUI arrest.
Dental Conditions: Oral health issues, such as gum disease, tooth decay, or infections, can harbor alcohol-producing bacteria in the mouth. These bacteria can ferment sugars into alcohol, leading to a false positive breath test result. In such cases, the alcohol detected in the breath does not come from the individual's consumption but rather from the bacteria present in the oral cavity. It's important for individuals with known dental conditions to inform their attorney about these factors during their defense strategy.
Respiratory Conditions: Respiratory conditions like asthma, bronchitis, or pneumonia can cause the individual to breathe more rapidly or heavily, resulting in the introduction of ambient air into the breath sample. This dilution effect can lead to lower BAC readings than the actual blood alcohol content. The presence of a respiratory condition may affect the accuracy of the breath test, potentially resulting in a false perception of lower intoxication levels. Individuals with respiratory conditions should discuss these factors with their attorney to explore possible defense strategies.
Stages of a DUI Criminal Case in Florida
- Arrest: The first stage of a DUI criminal case is the arrest. Law enforcement officers may pull over a driver suspected of driving under the influence based on observed erratic driving, traffic violations, or other signs of impairment. If the officer has probable cause, such as the smell of alcohol or failed field sobriety tests, they can make an arrest.
- Administrative Suspension: In Florida, upon being arrested for DUI, the driver's license is subject to administrative suspension. The driver has ten days to request a hearing to challenge the suspension through the Florida Department of Highway Safety and Motor Vehicles (DHSMV).
- Arraignment: The arraignment is the court proceeding where the defendant is formally charged and enters a plea of guilty, not guilty, or no contest. It is essential to consult with an attorney to determine the most appropriate plea based on the circumstances.
- Pretrial Motions: During this stage, the defense and prosecution may file pretrial motions to exclude certain evidence or challenge the legality of the arrest. Motions may also be filed to suppress breath test results if there are reasonable grounds to believe they were obtained erroneously.
- Trial: If the case proceeds to trial, both sides present their arguments and evidence before a judge or jury. The defense can utilize the knowledge of medical conditions causing false positive breath test results to challenge the accuracy and reliability of the evidence.
