Can consuming coffee effectively lower your blood alcohol concentration (BAC) or sober you up?

Consuming coffee does not lower your blood alcohol concentration (BAC) or sober you up. The primary reason for this is that, while coffee contains caffeine, which is a stimulant, it does not have any effect on the liver's ability to metabolize alcohol. The liver processes alcohol at a fixed rate, and nothing can accelerate this process.

Even though individuals may feel more alert after drinking coffee, this alertness does not equate to reduced impairment. People may misinterpret the stimulant effects of caffeine as sobering up, leading to a dangerous misconception that they can safely drive after consuming coffee when they are still under the influence of alcohol. This understanding is crucial because it highlights the importance of recognizing one's level of intoxication and the risks involved in drinking and driving.
