Firstly, the American Cancer Society is greatly influenced by the pharmaceutical companies from which they get a great deal of their funding.  Think gum, patches, lozenges, Chantix, and, of course, counseling and extra ofc. visits.

Secondly, most e-cig companies (cigarette looking ecigs) are owned by the tobacco companies and are expensive IF you stick with them; but most vapers quickly go on to better, refillable gear.

Thirdly, the second and third generation ecigs (mods, vaporizers, pens) and refillable atomizers are owned by companies independent of tobacco and drug companies and once bought are used for a year and more depending on what battery type is used.  Far cheaper than combustible cigarettes and far cheaper than the small cigarette looking ecigs.

Fourthly, I do wish the authors of this "paper" would get a clue about vaping and it's costs before writing what at best is an "opinion piece."  It would have taken all of one week to go to several of their local vape shops and talked to the owners/managers, visit on line E-Cigarette-Forum.com and/or CASAA.org to achieve "some" knowledge of this topic.  There are vapers out there spending less than 30 cents a day after initial setup expense with reuseable, long lasting equipment.

Fifthly, NOT having medical expenses because of NOT having a health problem due to smoking those incinerating tubes of tobacco leaves SAVES a lot of money that can be spent elsewhere.....Like rent, food and diapers.  You would think the American Cancer Society would applaud that fact.
