What is alcohol?

Alcohol is a depressant drug. Depressants slow down the messages travelling between the brain and body.

What does alcohol look like?

Alcohol is a colourless fermented or brewed liquid made from ethanol and flavoured water.2 3

Effects of alcohol

There is no safe level of drug use. Use of any drug always carries some risk. It’s important to be careful when taking any type of drug.

The Australian guidelines recommend no more than 10 standard drinks a week and no more than 4 drinks in one day to reduce the risk of harm from alcohol-related disease or injury. 8,9

Alcohol affects everyone differently, based on:

  • size, weight and health
  • whether the person is used to taking it
  • whether other drugs are taken around the same time
  • the amount drunk
  • the strength of the drink

You may experience:

  • feeling relaxed
  • trouble concentrating
  • slower reflexes
  • increased confidence
  • feeling happier or sadder, depending on your mood1, 7

National alcohol guidelines

Based on the latest scientific evidence, new alcohol guidelines have been released to help reduce the risk of alcohol harm and improve the health of Australians.



If you take a large amount, you could overdose.

Call an ambulance straight away by dialling triple zero (000) if you or someone else has any of the following symptoms (ambulance officers don’t need to involve the police):

  • confusion
  • blurred vision
  • clumsiness
  • memory loss
  • nausea, vomiting
  • passing out
  • coma
  • death.1, 10, 11

Coming down

  • The following day after drinking alcohol, you may have a hangover. Its effects include: headache
  • diarrhoea and nausea
  • tiredness and trembling
  • increased heart rate and blood pressure
  • dry mouth
  • trouble concentrating
  • anxiety
  • poor or decreased sleep. 15,16

To sober up takes time. The liver gets rid of about one standard drink 9 an hour. Sweating it out with exercise, cold showers, coffee, fresh air, or vomiting won’t speed up the process. This may ease the symptoms, but it won’t remove alcohol from the bloodstream any faster. This means it may not be safe to drive17 or work the following day. 18

Long-term effects

Regular use of alcohol may eventually cause:

  • depression
  • poor memory and brain damage
  • difficulty getting an erection
  • difficulty having children
  • liver disease
  • cancer
  • high blood pressure and heart disease
  • needing to drink more to get the same effect
  • physical dependence on alcohol.7

Alcohol and mental health

Research shows a relationship between people who are dependent on alcohol and increased mental health issues. People with mental health issues may drink more alcohol to self-medicate. This can lead to longer-term anxiety and depression. 19, 20

Tolerance and dependence

People who regularly use alcohol can become dependent on the drug. They may feel they need alcohol to go about their normal activities like working, studying and socialising, or just to get through the day.

They may also develop a tolerance to it, which means they need to drink larger amounts of alcohol to get the same effect. People who develop a tolerance and dependence on alcohol experience more alcohol-related harms. 21, 2

Mixing alcohol with other drugs

The effects of drinking and taking other drugs − including over-the-counter or prescribed medications − can be unpredictable and dangerous, and could cause:

Alcohol + cannabis: nausea, vomiting, panic, anxiety and paranoia. 22

Alcohol + energy drinks (with caffeine 23), ice 24, speed or ecstasy 26: more risky behaviour, body under great stress, overdose more likely.

Alcohol + GHB 27 or benzodiazepines 28: decreased heart rate, overdose more likely.

More on Polydrug use

‘Polydrug use’ is a term for the use of more than one drug or type of drug at the same time or one after another.1 Polydrug use can involve both illicit drugs and legal substances, such as alcohol and medications.



Giving up alcohol after a long time is challenging because the body has to get used to functioning without it. Please seek advice from a health professional.

Withdrawal symptoms can start within a few hours after the last drinks and can last for two to seven days. Symptoms include:

  • sweating
  • tremors
  • nausea
  • anxiety, irritability, difficultly sleeping
  • seizure of fits
  • poor appetite
  • delusions and hallucinations
  • death.1, 2, 29

There are laws that govern how alcohol may be used. These laws may differ depending on the state, territory, or local area. For example, in some areas, local by-laws make it illegal to drink alcohol in public places such as beaches, parks and streets.

It’s an offence for a person who is under 18 years of age to buy, receive or drink alcohol on licensed premises, unless they are with a parent or guardian.

In some states in Australia, it’s also an offence to supply a person under 18 years of age with alcohol in a private home, unless the young person’s parent or guardian has given permission and the alcohol is supplied in a responsible manner. This is known as secondary supply.

It is illegal to drive under the influence of alcohol. 30

Penalties for breaking these laws can include fines, imprisonment, and disqualification from driving. 31

Employers have legal obligations in relation to health and safety of their workers and people who visit their workplace. 32
