The majority of Canadians use alcohol at social events, with meals, or because they like the taste and how it makes them feel. Alcohol, even with moderate use, can affect fertility, and increase a person’s risk for cancers (e.g., breast, esophagus), heart disease, stroke, depression, or injury. Alcohol affects men, women, and young people differently. Teens and young adults are especially vulnerable because their brains are undergoing rapid change. If alcohol is used in pregnancy, unborn babies are at risk of lifelong difficulties with social, behavioural, physical, attention, and learning difficulties. Research shows alcohol can affect the genetics of future generations.
