4 What are heated tobacco products? Products that heat tobacco leaf to deliver an inhaled aerosol Technology first introduced in the 1980s and 1990s two primary formats: 1) Carbon-tipped tobacco sticks lit with a lighter 2) Electronic devices that heat tobacco sticks or capsules Unclear whether combustion actually occurs; thus, use of the term heated tobacco products (HTPs) rather than industry term heat-not-burn 4

5 Crosswalking HTPs, E-cigarettes, and Cigarettes Characteristics* HTPs E-cigarettes Manufactured Cigarettes Electronic Flame-activated Contain tobacco leaf Can deliver nicotine Produce secondhand emissions Produce smoke Can deliver marijuana *Sometimes or always 5

6 Flameactivated HTPs Typically employ a carbon tip lit with a lighter User inhales until the tip glows red and product is activated; stick is disposed after use Packs of 20, similar size and shape of cigarette 3 iterations have been tested in U.S. (1989 Premier, Eclipse, 2015 Revo) 7/2/2018 6

7 HTPs pending FDA pre-market approval IQOS: Umbrella brand for PMI s multiple reduced risk product (RRP) platforms Compressed tobacco stick inserted into device, discarded after use. iqos store outlet in Tokyo Flavors Regular, Balanced, Mint, Menthol 14 drags per stick, 6 minute heat time before automatic shut-off, 1 stick per charge HeatSticks are sold in packs of 20, priced comparably to cigarettes 7/2/2018 7

8 HTPs available outside the U.S. Part 1 JTI PloomTECH heats capsules filled with granulated tobacco leaves Regular ( Balanced ) and menthol ( Cool Purple ) flavors Capsules sold in packs of 5; recharge every 5 capsules Activated by inhaling making it possible to enjoy the experience immediately and at anytime Capsule can be used several occasions before disposal. 7/2/2018 8

9 HTPs available outside the U.S. Part 2 BAT glo heats tobacco NeoStiks, packs of 20 glo ifuse is a hybrid that heats liquid and tobacco 20 sticks per battery charge Flavors: Bright Tobacco, Fresh Mix (mint), Zest Mix (citrus) NeoStiks are priced 2x higher than cigarettes and have an approx. 45% lower tax rate in Japan because they are lighter and taxes are applied by weight. 7/2/2018 9

11 SummerStyles 2017 Survey Web-based, cross-sectional survey of U.S. adults aged 18 years Online panel from GFK s KnowledgePanel Address-based probability sampling Weighted to U.S. Current Population Survey proportions JUN-JUL 17 Fielded by Porter Novelli during June-July ,107 respondents completed SummerStyles 74% response rate 11

12 Measuring Awareness of Heated Tobacco Products Survey Question: Response Options: Heat-not-burn tobacco products heat tobacco sticks or capsules to produce an aerosol or vapor. They are different from electronic vapor products such as e- cigarettes, which heat a liquid to produce an aerosol or vapor. Some brands of heatnot-burn tobacco products include iqos, glo, Ploom TECH, and Revo. Before today, have you heard of heat-not-burn tobacco products? Yes No Don t know/not sure 12

13 Measuring Ever Use of Heated Tobacco Products Response Options: Have you ever tried a heat-notburn tobacco product, even just one time? Yes No Don t know/not sure 13

16 Potential future steps Include illustrated images in future surveys to assist respondents Revise questions to reflect current brands as needed Potentially revise heat-not-burn terminology in future survey questions As products become available, potentially add related questions to large nationally representative surveys 16

17 Key takeaways The landscape of tobacco products is continually changing By being proactive and looking at new product offerings outside the U.S., we can prepare our surveillance systems to track changes in tobacco use Probability-based samples can inform larger surveillance systems down the road Understanding unique properties and health implications of each tobacco product can inform public health planning, policy, and practice 17

25 Purpose of Truth Initiative JUUL studies: To learn more about JUUL awareness, use, perceptions and terminology

26 JUUL Studies Utilized online convenience panel sample weighted to national population. Two Surveys Conducted: First Survey Age: N=1,012 Data collected 11/22/17 11/28/17. During this period, JUUL represented 40% of e-cig dollar share. Second Survey Age: N=2,575 Data collected online, 4/3/18 to 4/9/18. During this time, JUUL represented 60% of e-cig dollar share.

59 Key Takeaways The tobacco product landscape has and continues to diversify over time. In 2016, about 3.2% of U.S. adults currently used e-cigarettes some days or every day. Considerable variations exist by sex, race/ethnicity, age, and region. Since 2014, e-cigarettes have been the most commonly used tobacco product among U.S. youth; in 2017, about 2.1 million middle and high school students reported using e-cigarettes in the past 30 days. The next generation of tobacco products, including novel e- cigarettes, have important implications for tobacco control surveillance and practice. 59
