Do Vape Flavours Damage Lungs? What Research Says

Vape flavours have taken the UK by storm, from fruity bursts to cool menthols and rich dessert blends. But, as the range of flavours expands, many are wondering: Do vape flavours damage lungs? There are several common myths about vape flavours and lung health, which this article will clarify. The answer, according to current UK research overall, is still unfolding. Let’s explore what science says so far, and discover what it means for you as a responsible vaper.

The British Medical Association has highlighted the need to closely monitor the safety of flavour additives in e-liquids, citing emerging evidence of potential respiratory impacts, especially after heating.

Flavours and Lung Health: What We Know So Far

E-liquids are made up of four main ingredients: Propylene glycol, vegetable glycerin, nicotine and food-grade flavourings. Because e-liquids do not contain tobacco, vaping avoids combustion. Also, vaping doesn’t produce tar or carbon monoxide, which are two of the most damaging elements in tobacco smoke. For this reason, experts agree that vaping is a less harmful alternative to traditional cigarettes.

The focus now is on understanding how long-term flavour inhalation may affect people who’ve never smoked before. When it comes to buttery flavours, concerns about diacetyl exposure originally arose from cases of lung disease among workers in microwave popcorn factory environments. Fortunately for UK-based vapers, diacetyl is banned in the UK.

A Closer Look Into E-Liquid Ingredients

When it comes to vaping, understanding what’s actually in your vape juice is essential for making informed choices. E-liquids, commonly referred to as vape juices, are the core component of electronic cigarettes (e-cigarettes) and are responsible for creating the vapour you inhale.

Most e-liquids are made from a blend of propylene glycol (PG) and vegetable glycerin (VG), which form the base of the mixture. PG is a clear, odourless liquid that’s known for carrying flavours effectively and delivering a satisfying throat hit, similar to what you might experience with traditional cigarettes. VG, on the other hand, is thicker and produces those thick clouds many vapers enjoy.

To give each e-liquid its unique taste, manufacturers add food-grade flavourings, resulting in the wide variety of e-cigarette flavours available today. Nicotine is another key ingredient, but it’s optional. Many e-liquids are available in nicotine-free versions or with varying nicotine strengths to suit different preferences.

Nicotine-Free Doesn’t Mean Risk-Free

While some e-liquids are nicotine-free, many do contain nicotine which is known for its addictive properties. That’s why vaping should only ever be used as a tool for adult smokers to stop smoking, and never used by a non-smoker or a person under the age of 18.

When used exclusively for the purpose of reducing nicotine intake, the NHS states that smokers are twice as likely to stop smoking.

What the UK Regulations Guarantee

Unlike unregulated markets, the UK’s vaping industry operates under strict safety standards. All vaping products must comply with the Tobacco and Related Products Regulations (TPD), which covers ingredient quality, bottle size, and labelling transparency.

That means when you buy TPD-compliant vape flavours, you can trust they’ve passed stringent safety checks before reaching your device. It is important to purchase regulated vaping products from reputable sources to ensure quality and compliance with UK laws.

Vaping and Public Health: The Bigger Picture

Vaping’s role in public health is a topic of ongoing debate, with both potential benefits and risks under the spotlight. Nicotine itself is highly addictive and can have lasting effects on the developing brains of young people, increasing the risk of dependence and making it harder to stop smoking in the future.

Some studies have also linked certain chemicals in e-liquids to an increased risk of lung cancer and other lung diseases, though these risks are generally lower than those associated with tobacco cigarettes.

There’s a clear takeaway here: vaping should only be used as a tool to support smokers in swapping to stop. When used by adult smokers as a less harmful alternative to cigarettes, vaping has clear benefits including helping smokers reduce their exposure to the hundreds of harmful chemicals produced by burning tobacco.

Experts recommend choosing e-cigarette products carefully and opting for those with lower nicotine strengths. It's also advisable to avoid unregulated or unknown ingredients and to only use devices that meet UK safety standards.

Finding Balance in Flavour

Moderation is key, both in flavour choice and vaping habits. In the UK, the number of e-cigarette users continues to rise, with many former smokers switching from smoking cigarettes to vaping as a less harmful alternative with the potential to gradually stop nicotine consumption altogether. This shift highlights the potential of vaping as a smoking cessation tool, especially among adults seeking to stop using tobacco products permanently.

Compared to other methods of quitting, such as nicotine replacement therapies, vaping may offer more rapid nicotine delivery and a sensory experience similar to smoking, which some users find more effective. Some vape-liquid formulations use nicotine salts to provide faster nicotine absorption, closely mimicking the effect of traditional cigarettes. Choosing the right nicotine strength and type of vape-liquid can help manage withdrawal symptoms and reduce urges to smoke, supporting successful quitting.

The NHS states that, compared to smoking cigarettes, vaping exposes users to fewer harmful toxins, which may reduce the risk of serious health conditions like heart disease.

Final Thoughts

So, are vape flavourings harmful? The short answer: There’s no simple yes or no. While certain additives might cause mild irritation in lab conditions, the regulated products available in the UK meet high safety standards.

Vaping remains a harm-reduction option for adult smokers, not a lifestyle trend for non-smokers. As science evolves, what’s clear is that informed choices and regulated products make all the difference.
