As vaping continues to gain popularity in the UK and around the world, questions about health impacts — particularly regarding second-hand vapour — are bound to come up. Unlike the well-documented dangers of second-hand cigarette smoke, the potential effects of exhaled vapour from e-cigarettes remain a topic of scientific exploration and public curiosity.
At FREESMO, we support responsible vaping and informed decision-making. We proudly provide top-quality vape kits, e-liquids, and coils designed for adults who are looking for a cleaner, more modern alternative to traditional tobacco products. In this article, we’ll take an honest look at what second-hand vapour is, what current research says, and why vaping continues to stand out as a smarter, harm-reduction alternative — not just for users, but for society.
Second-hand vapour refers to the aerosol exhaled by a person using an e-cigarette or vape device. This vapour is created when e-liquid — typically composed of propylene glycol (PG), vegetable glycerin (VG), nicotine, and flavourings — is heated by a coil. Unlike cigarette smoke, which involves combustion and the release of thousands of harmful chemicals, vapour is not smoke. According to a 2024 study led by researchers at University College London (UCL), it dissipates more quickly, carries significantly fewer toxins, and lacks the lingering odour associated with tobacco.
At FREESMO, our carefully curated range of vape kits and e-liquids ensures that our customers get high-quality, UK-compliant products that deliver flavour and satisfaction without unnecessary additives.
One of the most common concerns is whether second-hand vapour is dangerous to bystanders. Research to date strongly supports the fact that vaping is far less harmful than smoking — not just to the user, but also to those nearby.
According to Public Health England, vaping is estimated to be at least 95% less harmful than smoking tobacco. Their landmark review continues to shape the UK’s supportive stance on vaping as a key harm-reduction tool. When it comes to second-hand vapour, studies show that while trace levels of nicotine and flavouring compounds may be detectable in enclosed spaces, they are orders of magnitude lower than what’s found in cigarette smoke.
For the average bystander, exposure to second-hand vapour in well-ventilated areas reduces health risks compared to poorly ventilated spaces or traditional cigarette smoke — a point that health authorities across Europe and the UK increasingly acknowledge (National Library of Medicine NHL).
Let’s set the record straight — vapour is not smoke. Here’s how they compare:
| Feature | Second-Hand Smoke | Second-Hand Vapour |
|---|---|---|
| Composition | Over 7,000 chemicals, including 70+ known carcinogens | A few key ingredients: PG, VG, nicotine, flavourings |
| Smell | Pungent, long-lasting | Light, often pleasant aroma |
| Visibility | Dense, lingering smoke | Light vapour that quickly dissipates |
| Health Risks | Known to cause cancer, heart disease, respiratory illness | Extremely low; no long-term harm proven in bystanders |
The differences are night and day. Vaping does not produce carbon monoxide, tar, or ash — all hallmarks of cigarette smoke. That’s why switching to vaping is not only beneficial for smokers themselves, but also for those around them.
At FREESMO, we believe vaping is more than just a habit — it’s a choice toward a better lifestyle. We encourage all vapers to use their devices mindfully and respectfully, especially around children, pregnant women, or non-vapers.
While the health risks of passive vaping are negligible, being considerate goes a long way in maintaining a positive image for the vaping community. That’s why we offer vape devices that suit every lifestyle — from discreet MTL (mouth-to-lung) kits with minimal vapour output to DL (direct lung) setups for enthusiasts who prefer rich, full-flavored clouds.
Whatever your preference, FREESMO has the right tools to help you vape responsibly while enjoying every puff.
Here’s what’s actually in second-hand vapour, and why it's less of a concern than some think:
At FREESMO, we ensure every e-liquid we sell is UK-compliant and TPD-certified, meaning it meets strict safety standards and ingredient transparency.
While vaping isn’t banned in most public places, common courtesy matters. FREESMO advises customers to:
Remember, part of enjoying your device is knowing how to use it in a way that makes everyone feel comfortable.
It’s true that confined areas with poor ventilation — like cars or small rooms — can concentrate any airborne particles, even vapour. However, even under these conditions, studies show that the exposure levels of toxins remain very low. If you vape indoors, simple solutions like opening a window or using an air purifier can greatly reduce any buildup.
FREESMO’s compact and efficient devices allow for a smoother and more controlled vaping experience, especially in indoor environments. Devices like the VooPoo Drag S2 Pod Vape Kit or Vaporesso XROS Pro Pod Vape Kit offer a perfect blend of discretion, performance, and flavour.
While the risks from second-hand vapour are minimal, extra caution should be taken around:
It’s not that vapour is inherently harmful — it’s just best practice to avoid unnecessary exposure. FREESMO supports harm reduction through awareness. That’s why we educate our community to make smart decisions while still enjoying the full benefits of vaping.
Vaping isn’t just a substitute for smoking — it’s a growing community of conscious adults who value flavour, technology, and wellbeing. At FREESMO, we’re proud to be part of this movement by offering quality products, transparent ingredients, and trusted support.
