Blood alcohol
Blood alcohol (also known as blood alcohol concentration or BAC) is a measure of the amount of alcohol present in a person's bloodstream. It is usually measured as a percentage by volume or by mass. The legal limit for blood alcohol concentration in many countries is 0.08% (80 mg/dL), but this can vary.
Measurement[edit | edit source]
The most common method of measuring blood alcohol concentration is through a breathalyzer test. This involves blowing into a device that can measure the amount of alcohol in the breath, which is then used to estimate the amount of alcohol in the blood. Other methods include blood tests and urine tests.
Effects[edit | edit source]
The effects of alcohol on the body can vary depending on the blood alcohol concentration. At lower levels, alcohol can cause relaxation, lowered inhibitions, and a feeling of euphoria. At higher levels, it can cause dizziness, nausea, unconsciousness, and even death. Long-term excessive drinking can lead to alcoholism and other health problems.
Legal implications[edit | edit source]
Driving under the influence of alcohol is illegal in many countries, and penalties can include fines, imprisonment, and loss of driving privileges. The legal limit for blood alcohol concentration can vary, but it is typically around 0.08%.
