The American Cancer Society has altered position on electronic cigarettes as of February, 2018. The Cancer Society is now saying that based on current evidence, electronic cigarettes are less harmful than smoking tobacco cigarettes.
In fact, the organization that has historically been adversarial toward vaping is now recommending that clinicians advise that switching to electronic cigarettes is preferable to smoking.
American Cancer Society On E-cigs
The American Cancer Society still recommends that smokers use FDA approved smoking cessation methods. They are still wary of e-cigs because of the lack of long-term studies. No one is saying electronic cigarettes and vaping are risk free but the body of evidence is moving toward acknowledging reduced risk tobacco products.
The Cancer Society says that smokers who do not attempt to quit using an approved smoking cessation method should be advised to use e-cigs. This is the direct quote:
Some smokers, despite firm clinician advice, will not attempt to quit smoking cigarettes and will not use FDA approved cessation mediations. These should be encouraged to switch to the least harmful form of tobacco product possible; switching to the exclusive use of e-cigarettes is preferable to continuing to smoke combustible products.
Ultimately, ACS recommends that adult tobacco consumers should quit all forms of tobacco.
It should be noted that these are the views of the American Cancer Society. The FDA has yet to affirm this position. Electronic cigarettes are not recognized as a smoking cessation device.
