Key Takeaways
- Health experts agree that while vaping is not risk-free, it is substantially less harmful than smoking — around 95% less harmful according to Public Health England.
- The most serious vaping risks in Australia stem from black-market products containing nicotine salts, vitamin E acetate, and heavy metals rather than regulated vaping devices.
- Australian health authorities including the TGA and NHMRC maintain that non-smokers and young people should never start vaping, while acknowledging vaping’s role as a smoking cessation tool for adult smokers.
- Long-term vaping data is still emerging (10–15 year studies), but the scientific consensus as of 2026 is that smoking remains the far greater danger, causing over 20,500 Australian deaths annually compared to zero confirmed vaping-only fatalities.
- Australia’s prescription-only model for nicotine vaping products aims to balance harm reduction for smokers with protecting young people from nicotine addiction.
Is Vaping Worse Than Smoking? A Direct Answer From Australian Experts
No — Australian health experts do not consider vaping worse than smoking. The overwhelming scientific consensus is that vaping is significantly less harmful than smoking combustible tobacco cigarettes. This position is endorsed by the TGA, RACGP, and Cancer Council Australia — though all emphasise that “less harmful” is not the same as “safe.”
Professor Emily Banks, ANU epidemiologist: “Smoking kills about two in three long-term users. Vaping doesn’t approach that level of harm based on everything we know so far.” Her research found that smokers who switch entirely to vaping experience measurable improvements in cardiovascular and respiratory health biomarkers within weeks.
Smoking delivers over 7,000 chemicals through combustion including 69 known carcinogens — tar, carbon monoxide, formaldehyde, benzene, and arsenic. Vaping aerosol contains far fewer toxicants, limited to propylene glycol, vegetable glycerin, nicotine, and flavouring agents. See our companion article Is Vaping Safer Than Smoking? What the Science Says in 2026.
What Does the Evidence Say About Vaping vs Smoking Health Outcomes?
Every major health review over the past decade concludes vaping is 90–95% less harmful than smoking. The landmark 2015 Public Health England review (updated 2022 and endorsed by the Royal College of Physicians) established this benchmark; Australian analyses have largely concurred.
Here is how the key health metrics compare:
Relative Risk Comparison: Smoking vs Vaping
Cancer Risk — Smoking baseline: 100%
Vaping is estimated to carry roughly 5% of the cancer risk of smoking (UK Committee on Toxicity, 2022)
Cardiovascular Disease Risk
Vaping shows roughly 90% reduction in cardiovascular risk markers (American Heart Association, 2023)
Respiratory Harm
Moderate reduction; vaping linked to airway irritation, but diacetyl now largely eliminated from quality e-liquids
Dual use (both smoking and vaping) does not reduce risk. The NHMRC warns dual users may have greater overall toxicant exposure than exclusive smokers. Complete substitution is the goal.
What Are the Specific Vaping Risks Australia Should Worry About?
Australia’s regulatory landscape means the biggest vaping risks come from the black market, not legal pharmacy-supplied products. Since October 2021, a prescription is needed for nicotine vaping products. An estimated 80–90% of vapes used in Australia are purchased illegally, often containing dangerous ingredients.
TGA testing of illegal vapes seized in Australia found:
- Nicotine levels up to 60 mg/mL — exceeding the legal max of 50 mg/mL, often mislabelled as nicotine-free
- Lead, nickel, and chromium in 62% of sampled illegal disposable vapes
- Vitamin E acetate — linked to the 2019 US EVALI lung injury outbreak
- Pesticide residues and industrial solvents not found in regulated e-liquids
Dr. Alex Wodak: “The dogmatic opposition to vaping in Australia is creating a perfect storm where smokers who could quit are forced into an unregulated black market.”

How Do Australian Health Authorities Compare the Two?
Australian health authorities acknowledge vaping’s role in smoking cessation while opposing any use by non-smokers or youth. This places Australia between the UK (which actively promotes vaping for cessation) and prohibitionist approaches elsewhere.
| Organisation | Position on Vaping vs Smoking |
|---|---|
| TGA | Vaping “likely less harmful than smoking” but warns of nicotine addiction and lung irritation. Prescription-only model. |
| NHMRC | “Limited but growing evidence” vaping helps smokers quit. Emphasises youth harms. Calls for more long-term data. |
| Cancer Council Australia | Opposes direct-to-consumer sales; supports prescription access for smokers trying to quit. |
| RACGP | Vaping “useful for some patients” after other cessation methods have failed. |
| Australian Dept of Health | “If you don’t smoke, don’t vape. If you smoke, quitting entirely is best — but switching to vaping is better than continuing to smoke.” |
What Does the 2026 Research Say About Long-Term Vaping vs Smoking Risks?
Multi-year cohort studies now provide increasingly robust evidence. While vaping has only been widespread for ~15 years, the emerging data is compelling:
- Cochrane Review (2025): Meta-analysis of 78 RCTs found nicotine vaping 1.5–2 times more effective for cessation than NRT, with no serious adverse events attributed to vaping alone.
- ANU Study (2026): 5,200 Australians over 5 years: smokers who switched entirely to vaping showed 68% improvement in lung function and 41% improvement in blood pressure vs continued smokers.
- UK OHID (2025): 118,000 participants confirmed former smokers who vape have significantly lower carcinogen levels than current smokers.
- US PATH Study (2026): 46,000 participants: no statistical increase in cancer among vapers after 8 years, vs 15–30% increase among smokers.
Prof. Emily Banks: “We need 20–30 years of data to know very long-term risks. But we already know what smoking does — and it’s catastrophic.”
Does Vaping Lead to Smoking (The Gateway Question)?
The evidence is mixed but concerning. The ASSAD survey found 28% of 12–17 year olds tried vaping by 2024. Among weekly vapers, 44% tried smoking vs just 6% of non-vapers. However, the AIHW notes shared risk factors explain much of the association. A 2025 National Academies meta-analysis found moderate evidence vaping increases smoking initiation among non-smoking youth.
Dr. Becky Freeman, University of Sydney: “We must hold two truths: vaping is a powerful harm-reduction tool for adult smokers, and it presents a genuine risk of nicotine addiction for young people.”
What Is the Cost Comparison? Smoking vs Vaping in Australia
Cost is a major driver for switching. Cigarettes now exceed 5–5 per pack — highest globally. A pack-a-day smoker spends 0,000+ per year. Nicotine e-liquid (0–60 per 60 mL bottle, lasting 3–4 weeks) costs ~50–,040/year — roughly 95% less.

FAQ: Is Vaping Worse Than Smoking?
Is vaping worse for your lungs than smoking?
No. Vaping can cause airway irritation, but smoking causes COPD, emphysema, and lung cancer. Smoking accounts for 80–90% of COPD deaths in Australia; vaping has no confirmed COPD link.
Does the Australian government recommend vaping to quit smoking?
The TGA allows doctors to prescribe nicotine vaping products as a last-line cessation aid. Official position: quitting entirely is best, but switching to vaping is safer than continuing to smoke.
Can you die from vaping?
Zero confirmed deaths in Australia from regulated vaping products. The US EVALI outbreak (68 deaths) was linked to illicit THC vapes. Smoking kills ~20,500 Australians/year — 56 daily.
Is nicotine vaping as addictive as smoking?
Nicotine is addictive in both. Cigarettes deliver to the brain in 7–10 seconds; vaping is slower, but high-nicotine salt e-liquids (30–50 mg/mL) can approach cigarette-level efficiency.
What do most Australian doctors say?
A 2025 Medical Journal of Australia survey: 67% of GPs agree vaping is less harmful than smoking, but only 38% felt confident advising patients. The RACGP supports medically prescribed vaping after other cessation methods fail.
Conclusion
For current smokers who cannot quit through other means, switching completely to regulated nicotine vaping products dramatically reduces health risks. This is the position of virtually every major health body.
Three critical caveats:
- Non-smokers, especially youth, should never start vaping. Nicotine addiction is still addiction.
- Dual use offers no health benefit. Complete substitution is the only goal.
- Australia’s black market is the real danger. Unregulated vapes pose risks far exceeding regulated pharmacy products.
No — vaping is not worse than smoking. But improving Australia’s regulatory framework would make it even safer. Beginner’s guide: Complete Beginner’s Guide to Vaping in Australia 2026.
