Alcohol

How does alcohol affect my health?

Alcohol can be harmful to your health. Physical, mental, emotional and social issues increase when someone uses alcohol:

  • At an early age
  • Often
  • In large amounts
  • When taking medicine or other drugs that interact with alcohol
  • When pregnant or planning to be pregnant
  • Frequently over a long period of time.

Short-term risks

Alcohol impairs reaction time, judgment, decision making, and can have serious, even deadly, consequences. Learn more about binge drinking.

Drinking more than 3 drinks (for women) and 4 drinks (for men) on any single occasion increases risk of injury and harm. Follow the low-risk drinking guidelines to reduce your risks.

Drinking a lot of alcohol in a short time makes it difficult for your body to get rid of the alcohol. Too much alcohol could lead to alcohol poisoning.

Long-Term risks

Alcohol causes at least 60 types of diseases and injuries, and contributes to more than 200 others. Long-term use of alcohol can lead to chronic illnesses including:

  • Cancer
  • Liver disease (cirrhosis)
  • Heart disease and stroke (high blood pressure)
  • Diseases of the stomach, digestive system and pancreas
  • Brain and nerve damage
  • Depression
  • Fetal Alcohol Spectrum Disorder (FASD) from maternal use during pregnancy
  • Alcoholism

Alcohol and cancer

Alcohol is linked to cancer of the breast, mouth, pharynx, larynx and esophagus, colon and rectum cancer, as well as liver and pancreas.

The more you drink, the higher your risk of cancer. The type of alcohol does not matter. Women should drink less than 1 drink a day for women; men should drink less than 2 drinks a day for men.

Benefits of alcohol

For most people the overall harmful effects of alcohol outweigh any benefits from low levels of drinking, particularly for women.

Healthy eating and physical activity are less risky ways to achieve health benefits. There are no health benefits to alcohol consumption for youth.

How to measure a drink? 

What is a standard drink?

The size and percentage (%) of alcohol matters.

Beer, coolers, ciders and wine contain different alcohol % and are served in different sizes. Bigger sizes and higher alcohol % increase the alcohol content.

In the picture below, all the drinks have the same amount of alcohol. Each drink is one standard drink. The bigger glass has a lower alcohol % and the smallest size has the higher alcohol % which is how they end up having the same amount of alcohol.

Image showing the standard drinks for, Beer at 5%, 341 ml, 12 oz in a typical bottle, wine at 12%, 142ml, 12 oz. in a glass and spirits (Hard Liquor) at 40%, 43 ml, 1.5oz

Read the label to learn the alcohol % and measure the size of your drink to estimate standard drinks.

Interested in calculating your standard drink amount?  Below is the formula to calculate or use an online calculator.

The number of standard drinks = (volume oz) X (alcohol %) / 0.6

What will happen?

Help to reduce the amount of times a child is exposed to alcohol marketing.

  • Limit shows, movies or magazines that use a lot of alcohol advertising.
  • Talk to your child about what is alcohol advertising.
  • Concerned? You can make a compliant here

The more ads we view the greater the influences on our views about alcohol making it seem that everyone is drinking. 

Did you know?

The more times a child views alcohol marketing  the lower the age they will start drinking, and they may drink more than their peers once they start

Reducing exposure of alcohol marketing can delay onset of drinking and reduce excessive drinking by young people.

Limit the number of alcohol outlets in any given area and reduce when and where alcohol is sold.

  • All community members can share opinions about new liquor license applications.
  • Concerned about a particular liquor license?

Alcohol outlet density is the concentration of places where alcohol can be sold in a certain area. Alcohol outlets include bars, restaurants, grocery stores and liquor or beer stores.

Did you know?

Alcohol outlet density is linked to community-based violence and alcohol-related problems especially when bars, night clubs, pool halls and gaming facilities are clustered.

Restricting the density of places where alcohol is sold has a direct effect to lower alcohol consumption which decreases alcohol-related problems.
