E-cigarettes and vaping

Vaping is the act of using an e-cigarette, or ‘vape,’ which are lithium battery-powered devices that use cartridges filled with liquids, or ‘juice.’ The liquids typically contain nicotine, artificial flavourings, and various chemicals, some of which have been shown to be toxic. The liquid is heated into an aerosol, or vapour, and inhaled into the user’s lungs.

Vaping in Australia

It is illegal to use, sell or buy nicotine for use in e-cigarettes in Australia without a prescription. Except for Western Australia, each state and territory allows the sale of non-nicotine vapes and e-cigarettes products for those aged 18 years and over.* ​

Recreational vaping by youths and young adults has increased significantly in the last few years, exposing children and non-smokers to harmful health impacts. In 2023, 14.5% of Australians aged 14-17 years currently vape and this increased to almost 20% for Australians aged 18-24 years.1 Despite causing known health harms, vaping products continue to be used recreationally by young people. ​

*Evidence shows the vast majority of non-nicotine vapes contain nicotine which is illegal.​

Some vapes are designed to look similar to tobacco cigarettes, cigars, and pipes, while others resemble everyday items, such as pens and USBs. Even though e-cigarettes do not contain tobacco many liquids still contain nicotine, which is highly addictive, as well as other chemicals. These chemicals can be toxic when they are inhaled. Some are included to add a fruit, alcohol, or confectionary flavour to the product. In a pioneering study, funded by Lung Foundation Australia, Minderoo Foundation and the Scottish Masonic Charitable Foundation WA, researchers at Curtin University tested the chemicals and toxicity of 52 flavoured e-liquids available for sale over the counter in Australia². The research unveiled a cocktail of chemicals which raise serious concerns about the safety of these products and their risks to the respiratory health of young people.

The federal reforms (once implemented) will protect young people from the harms of vaping products, and we congratulate the Australian Government for taking strong action. States and territories across Australia continue to tackle growing vaping rates by seizing illegal nicotine vaping products from stores, introducing educational material into schools and running health campaigns to highlight the health harms of vaping.

E-cigarettes can serve as a “gateway” to nicotine addiction and tobacco cigarette smoking. There have been many studies which found experimentation with e-cigarettes encouraged the use of tobacco cigarettes, particularly among young people. According to the latest Australian Institute of Health and Wellbeing statistics 1 in 2 people aged 18-24 have used an e-cigarette at least once in their lifetime. Current use of e-cigarettes among young females has increased from 2.4% in 2019 to 20% in 2022-2023.⁴

Research of e-liquids available to purchase over the counter in Australia found 1 in 5 contain nicotine, among a concoction of other toxic chemicals – all had inaccurate labelling. With the inclusion of fruit, alcohol and confectionary flavours, e-cigarettes are designed to appeal to young people. Experts are concerned these products will create another generation of nicotine addiction and a rise in serious health issues including lung disease and cancer.

Lung Foundation Australia has developed a suite of resources to fill the knowledge gap around vaping and e-cigarettes. These resources are designed by and for young Australians, educators and parents and carers, to arm you with accurate and evidenced-based information.

Smoking cessation

In some cases, doctors can prescribe nicotine e-cigarettes as a means of weaning off tobacco use. There is little evidence that using this method is successful in achieving this outcome. Nicotine e-cigarettes should be a last resort for smoking cessation when other strategies are unsuccessful. From 1 October 2021, the Australian government introduced further restrictions to limit access to the use of nicotine e-cigarettes among adolescents and young adults. This included requiring a valid prescription to import nicotine e-cigarettes and liquids containing nicotine.

Vaping is unsafe and potentially dangerous. While the long-term health effects are unclear, we do know that vaping in the short-term has been associated with nausea, vomiting, mouth and airway irritation, chest pain and heart palpitations. There is a common misconception that vaping is merely harmless water vapour — in fact, it’s an aerosol made up of toxic particles.

These aerosols contain and emit many harmful compounds, including:

• Formaldehyde and acrolein, which can cause irreversible lung damage
• Propylene glycol, which is toxic to human cells
• Nicotine, which is highly addictive and can harm the still-developing adolescent brain, particularly in areas that control attention, learning, mood and behavioural control.

In 2022, the Australian National University released a review of the international evidence on the harms of vaping. ​

The health harms associated with vaping include: ​

• Nicotine addiction​
• Intentional and unintentional poisoning​
• Acute nicotine toxicity causing seizures​
• Burns and injuries​
• Lung injury​
• Indoor air pollution​
• Environmental waste and fires​
• Dual use with cigarette smoking – increasing exposure to harmful toxins.³​

Additionally, vaping is associated with the uptake of cigarette smoking and can be considered a ‘gateway’ to further risk and health complications. ​
