Facing a drunk driving charge can feel overwhelming. However, understanding the factors that affect breathalyzer results can be the first step in building a strong defense.

In this blog, we’ll explore the various elements that can influence breathalyzer numbers. After reading, you can gain valuable insight that may inform your defense strategy.

Factors that affect the result of a breathalyzer test

If a law enforcement officer suspects you are inebriated, they may ask you to take a breathalyzer test. Here are the factors that may increase your blood alcohol content (BAC):

  1. Gender: Women often have less of the enzyme that helps break down alcohol, known as alcohol dehydrogenase. This means women might register higher breathalyzer numbers than men even if they drank the same amount of alcohol.
  2. Body composition: Your body’s makeup plays a significant role in how alcohol affects you. People with a smaller stature may feel the effects of alcohol more quickly.
  3. Drug interactions: Mixing alcohol with other drugs can alter how your body processes the drink. This can lead to unexpected breathalyzer results and potentially dangerous interactions.
  4. Stomach contents: What you’ve eaten can impact your breathalyzer reading. A full stomach can slow down alcohol absorption, potentially resulting in lower breathalyzer numbers.
  5. Type of drink: The kind of drink you consume matters. Drinks with higher alcohol content can lead to higher BAC levels.

Understanding what influences breathalyzer numbers can be crucial for anyone facing drunk driving charges. By knowing these factors, you can better comprehend the circumstances surrounding your case.
