Why Vaping Myths Spread So Easily
Vaping has grown rapidly in the UK, and with it, a wave of misinformation. News stories often oversimplify, misunderstand chemicals or exaggerate risks. The truth is: vaping is not harmless, but it is scientifically recognised as a far safer alternative for people who smoke.
This guide cuts through the rumours and looks at what public health bodies — not headlines — actually say.
Myth 1: “Vaping causes popcorn lung”
The Myth
A claim that vaping creates the same lung condition caused by industrial diacetyl exposure.
The Facts
- Diacetyl is banned in all UK-regulated e-liquids.
- No vaper has ever been diagnosed with popcorn lung.
- Cigarettes contain far more diacetyl than any modern e-liquid.
Why it persists: It’s an emotional, headline-friendly story — but scientifically incorrect.
Myth 2: “Vaping is a gateway to smoking”
The Myth
"Teens who vape will start smoking."
The Facts
- Youth smoking rates continue to fall in the UK.
- Correlation ≠ causation — many studies show experimental vaping does not guarantee smoking.
- Regular vaping among never-smokers remains rare.
Myth 3: “Vapour contains deadly formaldehyde”
The Myth
Some studies using unrealistic temperatures claimed unsafe chemical levels.
The Facts
- "Dry puff" tests overheated devices to levels no user would tolerate.
- Normal vaping produces far lower toxin levels than smoking.
- Public Health England confirms vaping carries a fraction of the harm.
Myth 4: “Vape batteries explode all the time”
The Myth
Online videos suggest frequent unpredictable explosions.
The Facts
- Most incidents involve poor handling or unregulated devices.
- Use correct chargers, store batteries safely, and buy only branded kits.
- Regulated pod kits are extremely safe.

Myth 5: “Flavoured e-liquids are only for kids”
The Myth
"Adults only want tobacco flavour."
The Facts
- Most adult ex-smokers prefer fruit or dessert flavours — helps distance from tobacco.
- UK law bans sale to under-18s and regulates packaging heavily.
- Flavours increase success rates for quitting smoking.

Myth 6: “Nicotine causes cancer”
The Myth
The belief that nicotine is carcinogenic.
The Facts
- Nicotine is addictive — but not a carcinogen.
- The harm from smoking comes from combustion chemicals, not nicotine.
- Nicotine also exists in NHS-approved products like gum and patches.
Myth 7: “Second-hand vapour is as bad as smoke”
The Myth
"Passive vapour harms bystanders like cigarette smoke."
The Facts
- No evidence shows significant harm from passive vapour exposure.
- Vapour dissipates quickly and contains far fewer chemicals.
- Respect indoor rules and personal preferences.
What We Know For Sure — Evidence-Based Facts
- Switching completely from smoking to vaping reduces exposure to harmful chemicals.
- Vaping is not harmless, but is far safer than smoking.
- Adult vapers use flavours responsibly — a key factor in quitting success.
- Long-term effects continue to be researched, but current evidence supports harm reduction.
Final Thoughts
Misinformation spreads quickly — but the science is clearer than the headlines. If you smoke, vaping is a significantly safer alternative. If you do vape, choose regulated UK e-liquids, follow battery safety, and stay informed.
