The Educ’alcool Calcoholator lets you simulate how your blood alcohol level changes over a short period, based on information such as biological sex, weight, type of drink, volume consumed, alcohol percentage, time of consumption, and food intake.

The Calcoholator is an educational tool that provides a theoretical estimate of blood alcohol level based on the information entered. It never guarantees that a person can drive, and it does not replace a breathalyzer, professional judgment, or the rules set out in the law.

Try it: go to the Calcoholator to run an interactive simulation.

If you have been drinking, it is best not to get behind the wheel. There is no number of drinks that guarantees a person can drive safely. Alcohol can impair judgment, attention, coordination, and reaction time from the very first drinks, and its effects vary depending on the amount consumed, the pace of drinking, whether you have eaten, body composition, fatigue, medications, and other factors.

In Quebec, driving with a blood alcohol level equal to or over 80 mg of alcohol per 100 ml of blood is a criminal offence, but a person can also be arrested and convicted if their ability to drive is impaired, even below that limit. The zero-alcohol rule applies in particular to people under 22 and to holders of a learner’s licence or a probationary licence. Always refer to the official driving rules.

If you plan to drive, the safest choice is not to drink and to arrange your ride home before the first drink.

A blood alcohol calculator provides only an estimate and can never confirm that a person is fit to drive.

The Educ’alcool Standard Drink Pourer shows you what a standard drink looks like depending on the type of alcohol, its percentage, and the size of the glass. It helps you understand that a generous pour can amount to more than one standard drink.

Note: the type of drink—beer, wine, spirits, cider or cocktail—does not make drinking alcohol any less risky. What matters is the amount of pure alcohol consumed.

Use the Standard Drink Pourer to practise recognizing how much alcohol has been poured.

The Educ’alcool Count Your Drinks tool helps you become aware of how much alcohol you are drinking, on a single occasion or over a given period. See Count Your Drinks.

Yes. Educ’alcool’s interactive tools are free and available online. They are designed to educate, raise awareness, and help people make more informed choices. However, they never replace a professional assessment.

No. The results from Educ’alcool’s tools are educational estimates. They are not medical advice, an official blood alcohol measurement, a breathalyzer test, or permission to drive.
