The difference between vaping and smoking has become an increasingly common topic in Australia.
Although traditional cigarettes and e-cigarettes can both deliver nicotine, they work in fundamentally different ways. Cigarettes burn tobacco and produce smoke, while e-cigarettes heat a liquid to create an aerosol that is inhaled.
So, when comparing vaping vs smoking in Australia, what are the main differences?
This guide explains how cigarettes and e-cigarettes work, what users inhale, their health risks, nicotine dependence, and the current regulatory environment in Australia.
Important: Neither smoking nor vaping should be considered risk-free. People who do not currently smoke or vape should not start.

The biggest difference is combustion.
A traditional cigarette burns tobacco. During combustion, tobacco smoke containing thousands of chemicals is produced and inhaled into the lungs.
According to the Australian Institute of Health and Welfare, tobacco smoke contains more than 7,000 chemicals, with more than 70 known to cause cancer.
Smoking is associated with serious conditions including lung cancer, cardiovascular disease, stroke and chronic obstructive pulmonary disease (COPD).
E-cigarettes work differently.
Instead of burning tobacco, an e-cigarette uses a battery-powered heating element to heat a liquid and generate an aerosol.
This means vaping does not involve the same tobacco combustion process as cigarette smoking.
However, the absence of tobacco combustion does not mean vaping is harmless.
What Is Inside Cigarette Smoke?
Traditional cigarette smoke is a complex mixture produced when tobacco burns.
Australian health authorities identify substances associated with smoking including carbon monoxide, tar, formaldehyde and numerous cancer-causing chemicals.
Smoking can affect almost every organ in the body.
Long-term cigarette smoking is strongly associated with:
Lung cancer and numerous other cancers
Chronic obstructive pulmonary disease (COPD)
Heart disease
Stroke
Reduced circulation
Respiratory disease
Nicotine dependence
Smoking also exposes other people to second-hand tobacco smoke.
This extensive evidence is one reason tobacco smoking remains a major public-health issue in Australia.
What Is Inside Vape Aerosol?
E-cigarettes do not produce traditional tobacco smoke.
Instead, they heat an e-liquid to produce an aerosol.
Depending on the product, e-liquid may contain ingredients such as propylene glycol, vegetable glycerol, flavouring chemicals and nicotine.
It is important to understand that vape aerosol is not simply harmless water vapour.
Australian health authorities warn that e-cigarette aerosol may expose users to potentially harmful chemicals, and the long-term health effects of vaping are still being studied.
Nicotine-containing vapes can also lead to nicotine dependence.
Is Vaping Safer Than Smoking?
This question requires some context.
Smoking has an extremely well-established risk profile because burning tobacco exposes smokers to a large mixture of toxic and cancer-causing chemicals.
Vaping does not burn tobacco, so the exposure profile is different.
However, this should not be interpreted as meaning that vaping is safe.
Australian health authorities state that e-cigarettes can cause health harms, while evidence about some of their long-term effects continues to develop.
Therefore, a more accurate comparison is:
Smoking and vaping have different risk profiles, but neither should be described as harmless.
For someone who does not currently smoke, starting to vape is not recommended.
For an existing smoker considering vaping specifically as a smoking-cessation option, Australian authorities recommend discussing available treatments with a healthcare professional.
Cigarettes vs Vapes: Nicotine
Nicotine is another important part of the vape vs cigarette comparison.
Traditional cigarettes generally contain nicotine, and nicotine is highly addictive.
Many e-cigarettes also contain nicotine.
This means switching the method of nicotine delivery does not necessarily eliminate nicotine dependence.
Nicotine exposure can produce dependence and withdrawal symptoms when use stops.
The amount delivered can also vary substantially between vaping products, devices and patterns of use.
Smoking vs Vaping: Smell and Combustion
Another obvious difference is the way the products operate.
Cigarette smoking involves burning tobacco, which produces smoke, ash and a characteristic lingering tobacco smell.
Vaping does not burn tobacco and therefore does not create cigarette ash or conventional tobacco smoke.
Instead, the device produces an aerosol.
This difference in smell or visible emissions should not be confused with evidence of safety. An aerosol may still contain nicotine and other chemicals.
Smoking and Vaping Trends in Australia
Australia has experienced major changes in both cigarette smoking and vaping.
According to the Australian Institute of Health and Welfare's 2025 National Drug Strategy Household Survey, daily tobacco smoking among Australians aged 14 and over fell to 5.6% in 2025, compared with 8.3% in 2022–2023.
Daily e-cigarette use was 3.6% in 2025, compared with 3.5% in 2022–2023.
These figures show that cigarettes and e-cigarettes now form different parts of Australia's changing nicotine landscape.
Are Vapes Legal in Australia?
Australia has a particularly strict regulatory framework for vaping products.
Since 1 July 2024, vapes and vaping products can only legally be supplied through pharmacies for smoking cessation or the management of nicotine dependence, subject to Australian requirements.
Non-pharmacy retailers such as vape shops, tobacconists and convenience stores cannot legally sell vapes.
Adults aged 18 and over may access certain therapeutic nicotine vapes containing 20 mg/mL or less nicotine from participating pharmacies without a prescription, subject to pharmacist consultation and relevant state or territory laws.
Higher nicotine concentrations require a prescription.
Disposable single-use vapes cannot legally be purchased from pharmacies.
Australian therapeutic vaping products are also subject to restrictions on ingredients, packaging, labelling, flavours and product standards.
Consumers should therefore understand that the Australian market operates very differently from vape markets in many other countries.
Can Vaping Help Someone Quit Smoking?
Smoking cessation is one reason some adults research vaping vs smoking.
However, Australian health authorities do not currently recommend therapeutic vapes as the first-line treatment for smoking cessation.
First-line options include behavioural support and approved nicotine replacement therapies such as nicotine patches, gum and lozenges.
Therapeutic vaping may be considered in certain circumstances with guidance from a healthcare professional, particularly when other approaches have not worked.
The goal should ultimately be to stop cigarette smoking and, where possible, move toward becoming nicotine-free.
Vaping vs Smoking Australia: Frequently Asked Questions
Is vaping the same as smoking?
No.
Smoking burns tobacco and produces smoke. Vaping heats an e-liquid and produces an aerosol. The methods of operation and chemical exposure profiles are different.
Does vaping produce tobacco smoke?
No. E-cigarettes do not burn tobacco in the same way cigarettes do. They produce an aerosol by heating e-liquid.
Is vape aerosol just water vapour?
No.
Vape aerosol can contain nicotine and other chemicals. Describing it simply as water vapour is inaccurate.
Do cigarettes and vapes both contain nicotine?
Traditional cigarettes generally contain nicotine. Many vaping products also contain nicotine, although product composition varies.
Is vaping completely safe?
No.
Australian health authorities state that vaping is not harmless, and research into its long-term health effects is continuing.
Is smoking harmful?
Yes.
The health risks associated with tobacco smoking are extensively documented. Smoking is linked with cancers, cardiovascular disease, stroke, COPD and premature death.
Can I buy disposable vapes legally from Australian vape shops?
No.
Under current Australian regulations, non-pharmacy retailers cannot legally supply vapes. Single-use disposable vapes also cannot be purchased from pharmacies.
Final Thoughts: Vaping vs Smoking in Australia
When comparing vaping vs smoking, the most important distinction is that cigarettes burn tobacco while e-cigarettes heat a liquid to produce an aerosol.
The health consequences of cigarette smoking are well established, and tobacco remains a major contributor to disease burden in Australia.
Vaping avoids tobacco combustion, but that does not make e-cigarettes harmless. Vape aerosol can contain nicotine and other potentially harmful substances, nicotine dependence remains a concern, and research into long-term health effects continues.
For Australians who do not smoke or vape, the lowest-risk option is not to start.
Existing smokers who are considering vaping specifically to help quit cigarettes should discuss their options with a doctor, nurse practitioner or pharmacist and consider established smoking-cessation treatments.
