Alcohol

What is alcohol?

Alcohol is a depressant drug, which means it slows down the messages travelling between the brain and body.1

What does alcohol look like?

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

Other names

Booze, grog, piss, liquor, charge, plonk, bevvies, nip

Other types of depressants

How is alcohol used?

Alcohol is typically drunk in the form of beer, wine, cider or spirits. It can affect you quickly depending on the type of drink, as well as a person’s weight, height, health and amount consumed.4,5

Effects of alcohol

Use of any drug can have risks. 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.6

Alcohol affects everyone differently, based on:

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

You may experience:

  • feeling relaxed
  • increased confidence and energy
  • trouble concentrating
  • slower reflexes
  • clumsiness
  • slurred speech
  • feeling happier or sadder, depending on your mood1, 4, 5, 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.

Impact of mood and environment

Drugs that affect a person’s mental state (psychoactive drugs) can also have varied effects depending on a person’s mood (often called the ‘set’) or the environment they are in (the ‘setting’):

  • Set: a person’s state of mind, previous encounters with alcohol, and expectations of what’s going to happen. For example, feelings of stress or anxiety before drinking may result in an unpleasant experience and worsening of those feelings.8
  • Setting: the environment in which someone consumes alcohol. For example, heavy drinking tends to occur more when we’re with friends and at social events, and we can make more risky decisions in these environments due to lowered inhibitions.8

Overdose

If you drink 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 (Emergency services are there to help and can provide instructions over the phone):

  • slowed breathing
  • confusion
  • blurred vision
  • nausea, vomiting
  • passing out
  • coma.1, 6

Coming down

The following day after drinking alcohol, you may have a hangover. Effects include:

  • headache
  • nausea
  • tiredness and trembling
  • increased heart rate and blood pressure
  • dry mouth
  • trouble concentrating
  • anxiety
  • poor or decreased sleep.6, 9

Sobering up takes time – the liver gets rid of about one standard drink per hour.4 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 drive or work the following day.10, 11

Long-term effects

Regular and heavy use of alcohol can cause:

  • worsening of mental health conditions
  • 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 alcohol4-6

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 also drink more alcohol to self-medicate. Although alcohol might feel like it relieves symptoms of anxiety or depression in the short term, it is more likely to lead to longer-term anxiety and depression.12,13

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.3,14

Mixing alcohol with other drugs

Mixing alcohol with other drugs can have unpredictable effects and increase the risk of harm

  • Alcohol and cannabis: can cause nausea, impaired coordination, vomiting.
  • Alcohol and cocaine/ice/speed can feel less intoxicated due to the stimulant effect of methamphetamine/cocaine and lead to drinking more. Increases risk of alcohol poisoning.
  • Alcohol and benzodiazepines/GHB/heroin: high risk of overdose, may feel clumsy or uncoordinated, shallow breathing, nausea and vomiting, memory loss, passing out, and possible death.15

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. Polydrug use can involve both illicit drugs and legal substances, such as alcohol and medications.

Reducing harm 

There are ways you can reduce the risk of harm when drinking alcohol:

  • Follow the Australian drinking guidelines – no more than 10 standard drinks in a week and no more than 4 standard drinks at any one time
  • Drink water or other non-alcoholic beverages between alcoholic drinks.
  • Avoid drinking in rounds with friends, as you may end up drinking more than planned.
  • Order smaller serves of beer, cider and spirits, rather than pints or double serves.
  • Don’t let others top up your glass if you’re sharing a bottle of wine as you may lose track of how many drinks you’ve had.
  • Avoid high-alcohol content beverages, such as cocktails or spirits.
  • Set the number of drinks you’ll have, and count them to help you stick to it
  • Eat some food before and while drinking, to slow your drinking pace and slow the absorption of alcohol.
  • Occupy yourself while drinking to reduce the amount you’re consuming; play pool, sing karaoke, dance, talk to friends.6,15

Withdrawal

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 as alcohol withdrawal can be serious and sometimes cause death.16

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.1,6,16,28
