A first-ever Indian study has found that Electronic Nicotine Delivery System (ENDS), also known as e-cigarettes, pose much less a health risk than combustible cigarettes and could be an ideal tool to reduce or give up smoking.
Published in the Indian Journal of Clinical Practice (IJCP), the study, involving a “systematic review of 299 published scientific literatures”, was conducted by Prof R.N. Sharan and his team from the North-Eastern Hill University, Shillong. It compared the toxicities of nicotine, other chemicals and metal ions produced during cigarette smoking and use of e-cigarettes.
Prof Sharan told IANS: “This up-to-date systematic review and meta-analysis is the first attempt by experts in India to audit the health and safety aspects of conventional cigarette smoking and ENDS in order to objectively evaluate the suitability of ENDS as a less harmful alternative to conventional smoking.”
The study authoritatively concluded that newer generation ENDS was an efficient means of meeting the nicotine demand, and could help the cigarette smoking population quit the addiction and prevent tobacco harm reduction.
Speaking about the possible risks arising from the physical makeup or design of ENDS devices, the study warned that, “Poor materials and build quality, lack of quality control and improper use of ENDS can give rise to a potential accident hazard called “thermal runaway” in lithium rechargeable batteries.
However, the experts added that “with technological advancement and optimisation of safety features, these concerns can be adequately addressed.”
Finally, the authors of the study found that “ENDS usage was higher among former smokers than non-smokers by nearly 4.13 fold, signifying that they could potentially become a useful aid in smoking cessation.
“Also, use of ENDS was found to be 7.53 times higher in smokers than in non-smokers, which indicates that, contrary to perception, e-cigarettes are less likely to be a gateway to nicotine use but are more likely used by smokers to reduce tobacco harm or quit smoking.
