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.

Widely 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 unequivocal that vaping is much 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.
