True or False: The only accurate way to measure BAC is to count standard drinks consumed.

The statement that the only accurate way to measure BAC is to count standard drinks consumed is false. While counting standard drinks can provide a rough estimate of blood alcohol concentration (BAC), it fails to take into account several crucial factors that affect how alcohol is metabolized in the body.

These factors include an individual's weight, sex, age, metabolic rate, food consumption, hydration levels, and even specific health conditions. Since BAC can vary significantly among individuals even when they consume the same number of standard drinks, relying solely on drink counting is not an accurate method to measure BAC.

Various methods can provide an accurate measurement of BAC, such as blood tests, which directly measure the amount of alcohol in the bloodstream, and breath analysis, which estimates BAC through the breath alcohol concentration. Counting drinks can serve as a guideline but lacks the precision required for an accurate assessment.
