What is alcohol?
Alcohol is a depressant drug, which slows down messages travelling between the brain and body .1

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.
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 mood.1,2
The term 'binge drinking' generally refers to drinking heavily over a short period with the intention of getting drunk.
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 consume a lot of alcohol, you might experience:
- blurred vision
- memory loss
- nausea, vomiting
- passing out
The following day, you may have a hangover. Its effects can include:
- diarrhoea and nausea
- tiredness and trembling
- increased heart rate and blood pressure
- dry mouth
- trouble concentrating
- poor or decreased sleep.3,4
Sobering up takes time. The liver gets rid of about one standard drink an hour. Sweating it out with exercise, cold showers, coffee, fresh air or vomiting will not speed up the process. They may ease the symptoms, but they do not remove alcohol from the bloodstream any faster. This means it may not be safe to drive or work the following day.3,4
Long term effects
Regular use of alcohol may eventually cause:
- poor memory and brain damage
- difficulty getting an erection
- difficulty having children, see alcohol and pregnancy
- liver disease
- high blood pressure and heart disease
- needing to drink more to get the same effect
- physical dependence on alcohol.
Drinking 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.6
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 drink and can last for two to seven days. These symptoms can include:
- anxiety, irritability, difficulty sleeping
- seizures or fits
- delusions and hallucinations

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 is 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 is 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.
Penalties for breaking these laws can include fines, imprisonment and disqualification from driving.
Employers have legal obligations in relation to health and safety of their workers and people who visit their workplace.
