I'm going to add another paragraph based on
this publication by Joel Nitzkin. Something along these lines:
Calls to suppress, restrict, or ban electronic vaporizers are tantamount to the cold, calculated, and systematic murder of 44 million current American smokers, and 1.22 billion world-wide (Hanley 2014). Evidence presented by Nitzkin (2014b) suggests that propaganda, lies, and misinformation regarding
tobacco harm reduction (THR) perpetrated by TCI and disseminated by so-called "health" groups and public departments have already caused nearly 10 million unnecessary deaths related to smoking in the past 20 years alone (480,000 deaths per year × 20 years). Even under conservative assumptions regarding the success of THR initiatives using ecigs, Nitzkin (2014b) estimates that up to 4.8 million American lives could be saved over the next 20 years. Nitkin (2014b) concludes «[a] carefully structured
tobacco Harm Reduction (THR) initiative, with e-cigarettes as a prominent THR modality, added to current
tobacco control programming, is the most feasible policy option likely to substantially reduce tobacco-attributable illness and death in the United States over the next 20 years.»
