Alcohol is one of the most widely used drugs in the world. It is used and accepted in many societies, but excessive levels of alcohol consumption result in both short-term and long-term poor health.
Alcohol slows down the central nervous system and the brain, affecting concentration and coordination. It also slows down how quickly a person reacts to unexpected situations. Alcohol is absorbed very quickly into the bloodstream, affecting organs and cells throughout the body. The most immediate and noticeable effects are on the brain.

The guidelines also state that:
A standard drink contains 10 grams of alcohol. Different alcoholic drinks have different percentages of alcohol, so the amount of beverage in a standard drink varies. For example:
Note: These are only an approximate number of standard drinks. The label on the beverage container shows how many standard drinks it contains.

Foetal Alcohol Spectrum Disorders (FASD) are a range of disorders that are caused by being exposed to alcohol in the womb. These disorders are associated with a range of physical, behavioural and memory problems, some of which may not become apparent until a child reaches primary school.
Being exposed to alcohol in the womb can mean that a person may have permanent disabilities, may have mental health issues, may not do well at school, may find it hard to get or keep a job, and may have a high level of contact with the criminal justice system.
