How much does it take to make the breath machine show the max?

The "breath machine," often referring to a breathalyzer, measures blood alcohol content (BAC) based on the amount of alcohol in the breath. To register a maximum reading, typically around 0.40% BAC, an individual would need to consume a significant amount of alcohol in a short time frame, depending on factors like body weight, metabolism, and the type of alcohol consumed. However, reaching such a high BAC can be extremely dangerous and potentially life-threatening. It's crucial to prioritize safety and avoid excessive drinking.
