Introduction

I. What are E-Cigarettes?

II. How do E-Cigarettes fit into public health?

III.How is public opinion evolving?

IV.Why is FDA regulation so urgently needed?

What are E-Cigarettes? Regulatory Status

• A diverse category of rapidly evolving smoking substitute products

• Not regulated as drugs due to 2010 “Sottera” Federal District Court ruling that they are tobacco products if made using tobacco derived nicotine and not making drug claims

• Will be regulated by FDA CTP when Final Deeming Rule is released

• Sponsors may also seek approval of specific products as “drugs” for treatment of tobacco dependence and smoking cessation via CDER

Cigarette Smokingplummets to lowestlevels in decades asENDS experimentationrises – primarily amongalready smoking youth

(Adult smoking also falling)

CDC Director Thomas Frieden Seems to be out of step with NIH, FDA & the 2014 Surgeon General Report

His main reaction to data showing plummeting smoking in youth was great concern about youth ENDS use and to demonize ENDS, e.g.,

“We want parents to know that nicotine is dangerous for kids at any age, whether it’s an e-cigarette, hookah, cigarette or cigars” (April, 2015)

“…Nicotine exposure at a young age may cause lasting harm to brain development, promote addiction, and lead to sustained tobacco use.”

Henningfield response (New York Times, April 18, 2015):

“putting electronic products in the same basket as cigarettes is not truthful, credible or helpful.”

Wells Fargo 4Q 2014 U.S. E-cig Retailer Survey – Excerpts from "Tobacco Talk" by market analyst Bonnie HerzogWake Up Call! Action Needed To Keep Vapor Category Momentum Alive [Media scares: formaldehyde, heavy metals exploding E-Cigs]

(1) the FDA must take leadership and act soon to improve consumers' perception of the relative risks of vapor and uncertainty surrounding the category;

(2) the industry must align, particularly to push for modified risk claims so that public perception doesn't deteriorate further; …

Slade & Henningfield (FDLI Conference, 1998)

“…opportunities seem to exist to make tobacco products less poisonous and to improve public health in how they are made, labeled, marketed, and distributed…

thus, reducing morbidity and mortality caused by tobacco products… by offering a range of markedly less dangerous products to those who cannot or will not stop using nicotine.”

Recommended “harm reduction” as a complementary policy to prevention and cessation, integrated into tobacco control so as not to undermine prevention & cessation efforts

Mitch Zeller on Tobacco Harm Reduction

“…dare to envision a future world where almost no one uses combustible tobacco” - The strategic dialogue on tobacco harm reduction. Tobacco Control, 2009.

“One closing thought…. I absolutely understand the concerns… regardinge-cigarettes. Let’s not lose our focuson the primary cause of death—burning,combusting cigarettes.” CongressionalHearing, May 15, 2014

“FDA Commissioner Hamburg – Comments from Final Testimony to Senate, March, 2015

On Tobacco Deeming Rule:

“Public health-based regulation of These products [e-cigarettes] can help reduce the death and disease toll from tobacco use.”

a potential “flash

Summary

• Maximizing conditions that facilitate the transition away from combusted products is essential to improving public health

• Product standards that reduce nicotine content could serve as a “flash point” for reducing combusted product use and facilitating switching to alternative nicotine delivery systems

Public Support for Selected E-Cigarette Regulations

Andy Tan

FDLI 2015 Conference on FDA Regulation of Tobacco Products

October 21, 2015

Background

• Federal regulations for e-cigarettes are pending

• States and local communities have introduced regulations (bans in public, youth access, taxes)

• Assessed public support for six e-cigarette regulations

• Examined whether exposure to e-cigarette information was associated with support

Methods

• Online survey in July 2014

• Data from 527 adults 18+ years

• Outcomes were support for 6 policies

• Correlates were exposure to information, demographics, and tobacco use

Policies

There are currently proposals to regulate electronic cigarettes (e-cigarettes) in various ways. How much do you agree or disagree with the following statements?

1) Vaping or using e-cigarettes should not be allowed in places where smoking cigarettes is not allowed.

2) Youth under 18 years should not be allowed to buy e-cigarettes.

3) E-cigarette packages and advertisements should be required to carry an addiction warning.

Policies (cont’d)

4) The use of flavors in e-cigarettes should not be allowed.

5) E-cigarette packages should be required to label the amount of nicotine and other harmful ingredients.

6) Marketing and advertising e-cigarettes to youth under 18 years should not be allowed

Sample Characteristics

• Mean age 51.8 years (SD=16.4)• 50% female• 75% were non-Hispanic white• 31.5% completed college education or higher• 13% were current cigarette smokers• 4% have used e-cigarettes in the past 30 days

Trends in Public Support for Banning E-cigarette Use in Public Venues

Summary

• Moderate to high support for 5 of 6 policies, restricting use of flavors had lowest support.

• Recommend continued monitoring of public support for e-cigarette policies.

“To dismiss, misuse or under-use successful vapers’ insights and experiences as part of health services’ efforts to help smokers quit with reduced-risk products would, in my opinion, be a monumental missed public health opportunity,”
