Alcohol can affect how young people function, how they recognise risks, and their ability to make good decisions. Drinking makes young people more likely to put themselves in risky situations, which may result in harm to themselves or others. Alcohol is a depressant, which means that it slows down the brain.
Young people are at greater risk of alcohol-related harm than adults. As the brain keeps developing into the mid-twenties, drinking alcohol as a teenager can greatly increase the risk of damage to the developing brain. It can also lead to problems with alcohol later in life.
