About E Cigarettes
E cigarettes and vaping
Electronic cigarettes, known as e-cigarettes or vaporisers, are battery-powered devices, a cigarette substitute that provides small amounts of nicotine without the tobacco or other chemicals from real cigarettes.
E-cigarettes are made up of 3 parts:
- a tank to hold the e-liquid (contains the nicotine and flavouring)
- an atomiser to heat e-liquid (roughly 100 - 250 °C within a chamber)
- a battery to power the atomiser (1000 - 5000mAh approx)
The main substances making up in the liquid in the e-cigarettes are nicotine (which comes in varying strengths), propylene glycol, glycerin, and some flavours/ smells/ aromas ... from fruit favours, to bubblegum to coke. [Yes, we've just thrown up a bit in back of our collective throats]. The e-liquid is heated to make a vapour which looks like the smoke from real cigarettes carrying the nicotine to the lungs where it is absorbed.
Acknowledged that vaping is less harmful than smoking there is a focus on determining what issues and harms e-cigarettes and vaping may cause. Although not harmless, the evidence is that vaping is safer than smoking.
However, it's worth bearing in mind that the history of modern-day cigarettes has been going on for decades while the e-cigarette was only invented in 2003. So, the e-cigarette narrative has yet to run its course, and we have a lot still to learn, particularly concerning what damage and harms they may cause.
The recent spate of news about the harms and deaths vaping causes does not appear to bode well for either users, or the industry. Watch this space!

"The evidence to date suggests that vaping is not a safe alternative to smoking tobacco. This, coupled with the worrying trend of young, previous non-smokers being attracted to vaping, raises fears of yet another generation suffering from chronic lung disease. Indeed, a recent study in The Lancet estimates that in 2040, COPD will be the only disease in the top ten leading causes of death that will still be increasing. Although how much will be driven by vaping remains to be seen."
