Reducing the health and safety risks associated with drinking alcohol

Alcohol is the psychoactive substance that is consumed most by the Quebec population aged 15 and over. It is a drug that acts on the central nervous system.

Drinking alcohol increases the risk of developing at least seven types of cancer (mouth, larynx, pharynx, esophagus, liver, colon, breast) and about 200 diseases (stroke, pancreatitis, liver disease, epilepsy, dementia, addiction, etc.), in addition to increasing the risk of injuries or accidents for yourself and for others.

There is no safe limit. Every drink you do not have can make a real difference, even in the short term, by improving sleep for example. To reduce the health and safety risks, it is necessary to reduce your alcohol consumption.

To find out more about this substance, its harmful effects and what a standard drink is, go to the page Alcohol.

Tips for reducing your alcohol consumption

To reduce your alcohol consumption, here are a few tips:

  • Measure how much you drink using the standard drink value to calculate the quantities better
  • Alternate with non-alcoholic drinks (e.g., water)
  • Choose relaxing activities or socialize without alcohol
  • Set goals (e.g., do not drink alone, do not drink on certain days of the week, set a limit on the number of drinks)
  • Drink slowly

Reduce the risks if you drink

If you plan to drink alcohol, here is some advice to reduce the risk:

  • Eat before or while drinking to avoid having an empty stomach
  • Have non-alcoholic beverages available
  • Prioritize low-alcohol beverages
  • Pace your drinking
  • Alternate between alcohol and water to quench your thirst
  • Set a limit on how much you are going to drink
  • Drink slowly
  • To return home after a night out, walk, take public transport or call a loved one, a designated driver service or a taxi
  • Choose a person to be a designated driver, someone who will not drink, and give them your car keys
  • Wait for your body to get rid of the alcohol in your blood before driving. How long it takes to eliminate alcohol can vary depending on different factors, including your characteristics and the amount of alcohol consumed. If in doubt, avoid driving

Situations in which to avoid drinking alcohol

To reduce risks to your health and safety, you should avoid drinking alcohol:

  • If you plan on driving or operating machinery or equipment

  • If you are pregnant or planning to be
  • If you are breastfeeding
