Alcohol and Breathing: Understanding Respiratory Depression & BAC Limits

Alcohol does not directly cause someone to stop breathing. However, alcohol can lead to respiratory depression, which is a slowing down of the breathing rate. In severe cases, respiratory depression can lead to coma and even death.

The amount of alcohol it takes to cause respiratory depression varies depending on a person's age, weight, sex, and tolerance to alcohol. However, as a general rule, a blood alcohol content (BAC) of 0.30% or higher is considered to be life-threatening.

If you are concerned that someone is suffering from alcohol poisoning, call 911 immediately. Alcohol poisoning is a medical emergency that can quickly become fatal if not treated.
