The evidence emerging of potential dangers of e-cigarettes is sobering though less harmful than smoking.
Most reports come mainly from the US. As of February 2020 some 2,807 Users had been hospitalised with 68 deaths where vaping was cited as the cause. The World Health Organisation (WHO) states : “The evidence is clear that the majority of vaping systems can cause cancer and increased risks of heart and lung disorders. Both tobacco and e-cigarettes pose risks to health”
In a lab study in 2018 Dr Aaron Scott, a lecturer in respiratory science at Birmingham University found that the vapour that e-cigarettes induced produce many of the same cellular changes seen in cigarette smokers.
Even if vaping is only ten per cent as harmful as smoking perhaps it just takes longer to see those negative impacts.
