Blood Alcohol Level

Drink and drive offenses can be monitored by using Blood Alcohol Level (BAL) and many countries use either BAL or a breath analyzer.

Blood alcohol level (BAL) or Blood alcohol content (BAC) is the amount of alcohol in your blood stream.

It is calculated in milligrams of alcohol per hundred millilitres of blood or milligram percent. In some countries it is reported as grams of alcohol per litre (thousand millilitre) (Litre).

By using the number of drinks consumed and the time over it was consumed; one can calculates safe limits of alcohol consumption (See medindia BAC calculators link). However it is not a good measure of intoxication as there is a large variation in physiology and individual alcohol tolerance.

Even Dubai is quite strict for drunken driving. They take photos - from Police cameras and people get booked with hefty fines.

How does 30mg/100ml translate in terms of the amount of Alchohol that can be consumed by an individual and keep him within this safe limit. Will having a bottle of beer keep within this safe thresh hold. I know BAC depends on a lot of other factors...but I guess a safe limit can be arrived at in terms of bottles of beer.....or a CHOTA or a BADA peg.......Cheerio.
