Earlier this year vaping hit the headlines with reports of deaths in the United States linked to the use of e-cigarettes.
Vaping was the common factor, but a toxicologist from Imperial College London suggests the deaths could have been caused by oils or other unlicensed substances being added to the e-cigarette, rather than the approved contents of e-liquids.
While the jury is still out on the long-term health impacts of vaping, the evidence suggests that in the short to mid-term at least, switching from tobacco cigarettes to e-cigarettes could reduce the harm to smokers by as much as 95 per cent.
So is vaping to be embraced by smokers as a means to quit harmful tobacco, or shunned as another potentially health-harming habit?
