Does any alcohol consumption increase the risk to your health?
Many factors can affect your risk for these and other health harms including age, medication interactions, pregnancy or gender. For some people, drinking any alcohol is too much. Any decrease in the amount of alcohol you drink, will decrease your risk of cancer and other harms. 24

How are alcohol and cancer linked?
Alcohol is classified as a Group 1 carcinogen, meaning it is known to cause cancer. After drinking alcohol, the body breaks it down into acetaldehyde, a chemical that damages your DNA and prevents your body from repairing that damage. With the DNA damaged, a cell can begin growing out of control and create a cancer tumor.
Because alcohol is a carcinogen, lower levels of drinking can also be harmful even if you don’t feel drunk.25
Beyond our bodies
Drinking and motor vehicle deaths
The number of driving deaths that involve alcohol has more than doubled in Oregon in recent years, from 70 in 2010 to 191 in 2020. Oregon has one of the highest rates of alcohol-impaired driving deaths in the nation.18
Harms can happen in a flash
It can take years for excessive drinking to cause heart disease or cancer. Or it can end in death in a matter of hours or minutes, when it contributes to suicide, violence, and falls or other injuries. Binge19 drinking can lead to death by alcohol poisoning — most common among middle-aged men ages 35 to 64.
Uneven impact on communities
People in Oregon of all racial and ethnic backgrounds and at all income levels drink excessively. But the harms fall disproportionately on Black and Indigenous communities and people with lower incomes and less education, who experience higher rates of alcohol-related diseases and other harms.20
