How to achieve success B In September 2008 the World Health Organization issued a statement warning smokers that there was no evidence to back up claims that e-cigarettes could help them quit. So what do we know about them? E-cigarettes were invented by Hon Lik of electronics company Ruyan in Beijing, China. Ruyan sold its first electronic cigarette in May 2004, and e-cigarettes have been growing in popularity ever since. Accurate figures are hard to come by, but Ruyan — the world’s biggest manufacturer — claims to have sold over 300,000 in 2008. Smart Smokers, one company which sells Ruyan’s cigarettes in the UK, says sales are rising exponentially. In the US, hit TV show The Doctors featured the e-cigarette in the top 10 health trends of 2008. In a world where smoking is increasingly socially unacceptable, the e-cigarette looks like a success story in the making. The device itself is pretty simple. It resembles a normal cigarette in shape and size but instead of containing cured tobacco it is mostly full of battery and an LED. The disposable filter holds a cartridge containing nicotine dissolved in propylene glycol(丙二醇), the liquid that is vaporized in nightclub smoke machines. When you take a drag, a pressure sensor switches on an electric heating coil that vaporizes the PG and releases the “smoke”. The strongest cartridge contains about the same amount of nicotine as a regularstrength cigarette, but lasts for about 300 puffs in comparison with a regular cigarette that lasts for about 15. The cartridges don’t “burn down” but deliver a puff whenever you choose to take one. Cartridges come in high, medium, low and zero-nicotine strength and cost around $1. 50 each. However, on a per puff basis, the strongest cartridge only delivers around one-third the amount of nicotine delivered by a puff on a normal cigarette, says Murray Laugesen, a public health researcher who campaigned against tobacco smoking in New Zealand and is now studying the impact of smoking e-cigarettes. 36.
