Short-term harm is what may occur as a result of one (single) drinking occasion. The short-term harms of alcohol can not only impact the individual, but also family, friends and members of the community.

However, the more alcohol a person drinks, the more their feelings and behaviour change. When a person drinks too much alcohol, they may experience effects such as drowsiness, loss of balance and coordination, slurred speech, nausea and vomiting. More serious effects such as losing consciousness or breathing difficulty can be fatal. 1
