WHICH VAPE FLAVOUR IS WORSE FOR YOU?

If you're trying to quit smoking, you'll have probably heard talk that switching to e-cigarettes - or vapes - is a healthier option. One study by researchers at University College London estimated that in 2017 alone, over 50,000 people stopped smoking thanks to their use of e-cigarettes.

It's true that most of the compounds that cause smoking-related diseases aren't found in e-cigarettes (which, unlike heated tobacco products, don't burn tobacco), so vaping is safer in that sense. But if you've never been a smoker, it's not advisable to take up vaping.

The e-liquid that's used in vapes typically contains a mix of propylene glycol and glycerine. Both compounds are considered safe to ingest and though they haven't been officially labelled safe for inhalation, a 2020 review of clinical studies found "little impact on lung functions, as well as no significant inflammatory effects."
