What are drinking games?

Drinking games are contests or challenges during which a maximum amount of alcohol is consumed in a very short time. The practice is also known as binge drinking.

Drinking contests may take place casually, among friends, or be more formally organized by a bar or a club. They can be public or private, with or without spectators.

The games go by various names. Century Club, Quarters, Boat Races and Chug-a-Lug are a few you may have heard about.

The point is that these are all very dangerous “games” that can lead to severe intoxication and alcohol poisoning. The danger begins when your blood alcohol level hits 400 mg per 100 ml of blood (commonly referred to as .40). More than that, and there is a serious risk of coma and even death.

Drinking games = Danger

Many things can happen when you drink too much. The effects become more serious the more you drink, and the risk is extremely high when your blood alcohol level is over 200 mg per 100 ml of blood (.20).

How to calculate your blood alcohol level?

When it comes to drinking, there’s no point looking to your friends, no matter how nice they are. Everyone responds differently to alcohol, depending on various physical and emotional factors. How quickly you drink, how much you weigh and how much muscle mass you have can also affect how you react. And, unfair as it may seem, alcohol affects women more quickly than men. In terms of impact, an average drink for a woman is equivalent to a drink and a half for a man. So it’s very important to know exactly what your tolerance is.

Calculate your blood-alcohol content

These charts can help you determine what your blood alcohol level is likely to be after drinking. Please remember that these figures are approximate only.

Subtract 15 mg of alcohol per hour from the time you take your first drink, since that’s the rate at which your body eliminates alcohol.
