3. Smoking in the United States
Smoking rates within the U.S. have fallen consistently over recent years. But:
Around 480,000 deaths a year attributable to smoking
16.7% of men and 13.6% of women smoking in U.S.
Smoking costs the U.S. an estimated $11B a year.

4. E-Cigarettes Public Health and Public Policy
E-cigarettes represent an unmatched opportunity to improve the health of current smokers by enabling those smokers who cannot quit to switch to a much less harmful means of consuming nicotine?

5. FDA Commissioner Announcement on Tobacco Harm Reduction
Last Friday Commissioner Gottlieb made a major announcement embracing the principle of tobacco related harm reduction. FDA has identified reducing the nicotine content of combustible tobacco products as a key part of the new strategy. The contribution of reduced risk products including e-cigarettes have been recognized as having a key role to play in reducing the harms for those smokers who cannot quit. This is a major shift in policy.

6. E-cigarette use and associated changes in population smoking cessation: evidence from US current population surveys (Shu-Hong Zhu et al BMJ 2017)
The substantial increase in e-cigarette use among US adult smokers was associated with a statistically significant increase in the smoking cessation rate at the population level.

10. STEs initiated e-cigarette use for primarily health/harm reduction reasons.

11. Majority of STEs have experienced significant improvement in at least one respiratory symptom and one cardiovascular symptoms since switching to exclusive e-cigarette use.

12. Reduced Interest in Smoking

13. Majority of daily users have become less interested in smoking since becoming a daily e-cigarette user.

14. Role of Flavours

15. Daily users increasingly likely to initiate e-cigarette use with fruit-flavoured liquid; decreasingly likely to initiate with cigarette flavours.

16. Fruit, candy, and dessert/pastry flavours most popular current flavours with each group.

17. Reduced Nicotine Content

18. Daily users increasingly likely to initiate e-cigarette use with liquid containing 1-6 mg/ml nicotine; reduced initiation with mg/ml.

19. Current daily use within each group characterised by use of liquid containing 1-6 mg/ml nicotine.

20. Smokers Now Switching Earlier Away from Smoking to Vaping

21. Increased proportion initiating e-cigarette use as lighter smokers (1-10 CPD) over time, displacing heavier smokers (21-30 CPD).

22. Low Level of Addiction to E-cigarettes

23. Self Reported Dependence Measured Using Validated Scale (n= 17940)

24. The Problem
“I hate e-cigarettes. I hate the fact that they contain nicotine and come in flavors that are designed to attract kids. I hate the companies that make money out of selling e-cigarettes. We are never going to be saying to our young people “here try these, they are 95% less harmful than cigarettes”.” - San Francisco Public Health Official, 28 July 2017.

25. Maximising the Benificial Impact of E-Cigarettes
Ensure that a range of device types (closed and open systems) continue to be available.
Ensure that vapers can continue to access non smoking/tobacco related flavours.
Ensure that e-liquids in variable nicotine strengths continue to be available.
Do not stigmatise vaping as a sign of personal failure or a threat to public health.
Do not include vaping in smoke free policies.

26. Declaration of Funding
The U.S Vapers Survey was funded by Fontem Ventures. Fontem Ventures has had no role in influencing the collection of data, the analysis of data nor in the publication and presentation of the findings of our research.
