That tobacco kills is a fact. Globally, more than 60 lakh of these deaths are the result of direct tobacco use, while around 8.9 lakh are due to non-smokers being exposed to second-hand smoke. Smoking-related deaths are expected to increase to 80 lakh by 2030. Hence, it is important to reduce it, otherwise an estimated one billion lives will be lost prematurely by 2100, according to the Annual Review of Public Health. And this is where e-cigarettes come in.
