Regulatory Science to Policy: Update on e-cigarettes. David B. Abrams The Schroeder Institute For Tobacco Research And Policy Studies at Legacy. The Johns Hopkins Bloomberg School of Public Health Georgetown University Medical Center / Lombardi Comprehensive Cancer Center
Good afternoon. Scientific evidence is critical to inform the FDA and the field. The science , is very sparse. on emerging harm reduced products, especially on the meteoric rise of e cigs. However given how the industry (not just tobacco companies) and consumers are reacting, there appears to be a game changing shift occurring in the market place.
We now have an increasingly appealing set of products that can reduce harms it gives rise to a fundamental debate about the future of how nicottne is delivered and marketed

7. Major Shift: Harm Reduction ?
Despite 50 years progress, reduction in combustible cigarettes has slowed ...
As articulated in the 2014 Surgeon General’s 50th anniversary Report. Executive Summary (pages 15-17):
“Death... is overwhelmingly caused by cigarettes and other combustibles...
promotion of e-cigarettes and other innovative products is...
likely to be beneficial where
the appeal, accessibility and use of cigarettes are rapidly reduced.” ….and their cost is increased

16. YOUTH Patterns of USE. (Experimenting only and over 90% already use conventional cigs).
Adults: Awareness (76%) and use (21%) is growing fast among current smokers and young adults. Perceived as less harmful.
Youth (CDC MMWR 2013)
Use doubled middle and high school students 2011–2012, estimated 1.78 million students ever used.
During 2011–2012, among all students in grades 6–12, ever e-cigarette use increased from 3.3% to 6.8% (p<0.05) (Figure); current e-cigarette use increased from 1.1% to 2.1% (p<0.05), and current use of both e-cigarettes and conventional cigarettes increased from 0.8% to 1.6% (p<0.05). In 2012, among ever e-cigarette users, 9.3% reported never smoking conventional cigarettes; among current e-cigarette users, 76.3% reported current conventional cigarette smoking.
Among middle school students, ever e-cigarette use increased from 1.4% to 2.7% during 2011–2012 (p<0.05) (Figure); current e-cigarette use increased from 0.6% to 1.1% (p<0.05), and current use of both e-cigarettes and conventional cigarettes increased from 0.3% to 0.7% (p<0.05). In 2012, among middle school ever e-cigarette users, 20.3% reported never smoking conventional cigarettes; among middle school current e-cigarette users, 61.1% reported current conventional cigarette smoking.
Among high school students, ever e-cigarette use increased from 4.7% to 10.0% during 2011–2012 (p<0.05) (Figure); current e-cigarette use increased from 1.5% to 2.8% (p<0.05), and current use of both e-cigarettes and conventional cigarettes increased from 1.2% to 2.2% (p<0.05). In 2012, among high school ever e-cigarette users, 7.2% reported never smoking conventional cigarettes; among high school current e-cigarette users, 80.5% reported current conventional cigarette smoking.
E-cigarette experimentation and recent use doubled among U.S. middle and high school students during 2011–2012, resulting in an estimated 1.78 million students having ever used e-cigarettes as of Moreover, in 2012, an estimated 160,000 students who reported ever using e-cigarettes had never used conventional cigarettes. This is a serious concern because the overall impact of e-cigarette use on public health remains uncertain.

20. Conclusions and Relevance  Use of e-cigarettes was associated with higher odds of ever or current cigarette smoking, higher odds of established smoking, higher odds of planning to quit smoking among current smokers, and, among experimenters, lower odds of abstinence from conventional cigarettes. Use of e-cigarettes does not discourage, and may encourage, conventional cigarette use among US adolescents

21. Patterns Of Tobacco Use And Dual Use In U. S
Patterns Of Tobacco Use And Dual Use In U.S. Young Adults: The Missing Link Between Youth Prevention And Adult Cessation
51% had ever smoked cigarettes. First product used: 73% cigarettes, 11% cigars, 5% little cigars/cigarillos/bidis, 4% hookah
32% of ever users (18-34) reported product initiation after the age of 18
Of 23% of young adult current users, 30% report dual use. Among dual Users: cigars 23%, little cigars 26%, hookah 17%, dip snuff 12%, chewing tobacco 12%, e-cigs 9%, snus 7%, dissolvables 3%
Dual use - higher in younger adults, males, less than high school education, and those not able to meet their expenses.
Daily cigarette use was similar between dual use and cigarettes only use (no harm reduction due to less cigarettes, rather a harm increase?)
Data were gathered from a nationally representative sample of 2,649 American adults

22. Robust ongoing surveillance of NCP advertising is critical to inform the FDA and protect public health.
Both commercial advertising and public health media campaigns must ensure that content is not misleading and educates consumers about harm based on the available science.
The way messages are framed have the potential to decrease tobacco use by promoting rather than undermining cessation of combusted products and/or encouraging exclusive use of less harmful NCPs rather than poly-use of combusted and NCPs.

23. 7. Their ads say, “Switch, Don’t Quit.”
Tobacco companies have long tried to discourage smokers from quitting
by marketing cigarette changes as reducing health risk.
Some e-cigarette ads carry a similar message.

24. SCIENCE Questions: SUMMARY
Less harmful than cigarettes - when good quality can be regulated to be close to Pharama grade NRT. Some ingredients can produce harmful chemicals when heated (coloring / flavors)
How can does e-cigarette use and marketing maximize benfits and reduce harms and affect current smokers?
Delay cessation? Promote cessation?
Reduce cigarette consumption or give the impression of less harm because of imagined reduced cigarette consumption?
Dual use when one can not smoke and alleviate discomfort
Do e-cigarettes encourage former smokers to return to nicotine use and relapse to cigarette smoking?
How do e-cigarettes affect non-smokers ?
Potential uptake among youth and young adults
We do not know how e-cigarettes will affect public health. We do not know whether these products promote experimentation or initiation of tobacco products, facilitate nicotine addiction, lead to concurrent use of e-cigarettes and other tobacco products (dual use), increase or decrease dual users’ combustible cigarette consumption, or promote or impede smoking cessation.
No federal minimum age requirement for e-cig sales. Some anecdotal evidence and evidence from Minnesota among young

26. CAN E-cigarettes make lethal combustibles obsolete?
Harm reduced products update: Fiore, Schroeder, Baker. NEJM. Jan 2014; Abrams D JAMA Jan 2014
Communicate intelligently about harm reduction
Policy and Practice Proportional to HARM
Focus on eliminating combustible tobacco products - Not all nicotine-containing products are equal…
Even if some who give up combuseds will continue indefinitely using:
FDA-approved medicines, e-cigarettes, or smokeless (least harm is Swedish Snus).
  "New approaches must be adopted if we are to dramatically reduce the harms over the next decade. Goal requires that we recognize the unequal dangers resulting from combustible tobacco use.”
CAN E-cigarettes make lethal combustibles obsolete?

27. Conclusions
Stakes are high; lethality of combusted tobacco is worse than we thought
Alternative frameworks of addiction/appeal/harm are available
Taxes and Policies: Proportional to Harm of product class
End game strategies aided by future approaches and devices for nicotine delivery that better substitute for the cigarette pridetn regulation maximize benefits minimize harms
Promotion of e-cigarettes and other innovative products is much more likely to be beneficial in an environment where the appeal, accessibility, promotion, and use of cigarettes are being rapidly reduced

Excerpts from: Ending tobacco smoking in Britain; Radical strategies for prevention and harm reduction in nicotine addiction
Royal College of Physicians of London, 2008.
People smoke because they are addicted to nicotine, but nicotine itself is not especially hazardous; it is the other constituents of tobacco smoke that cause most of the harm.
Use of smoke-free nicotine would benefit smokers directly by reducing the personal harm caused by nicotine addiction.
“In Sweden, the availability and use by men of an oral tobacco product called snus, one of the less hazardous smokeless tobacco products, is widely recognised to have contributed to the low prevalence of smoking in Swedish men and consequent low rates of lung cancer.”

31. New FDA proposed deeming and future rulemaking
Restrict Sales to over 18 years of age, no free samples.
Warning Label that nicotine can be an addictive substance
Registration, and Product disclosure
Product standards, safe ingredients, child resistant packages
Substantial equivalence or new product application 2yr grace
MRTP applications to claim reduced harm: individual and population standard. Pre-approval and post-market surveillance
Advertising on TV and Targeting youth ?
Flavors attractive to youth (candy) ?
Therapeutic claims for smoking cessation?
Need comprehensive nicotine / tobacco regulatory policy

32. Lessons from the united kingdom
Department of Health committed in its 2011 Tobacco Plan to “develop new approaches to encourage tobacco users who cannot quit to switch to safer sources of nicotine”
In 2013, both the UK Medicines and Healthcare products Regulatory Agency (MHRA) and the National Institute for Clinical and Healthcare Excellence (NICE) issued guidances embracing tobacco harm reduction and a “light-touch” approach to regulating nicotine-containing products as medicines
Wide array of approved uses (e.g., reduce to quit, smoking reduction, temporary abstinence, maintenance)
A handful of applications are apparently pending and the first approval is expected this year
What could FDA glean from this experience?
