How to lower a persons bac?

To lower a person's blood alcohol concentration (BAC), the most effective method is to give the body time to metabolize the alcohol, as there is no quick fix. Encouraging the individual to drink water and eat food can help mitigate some effects of alcohol, but it does not accelerate BAC reduction. Ultimately, the liver processes alcohol at a consistent rate, typically about one standard drink per hour. If someone is severely impaired, it's crucial to seek medical attention.
