FDA held a second public scientific workshop on May 15, 2019 and requested comments about tackling youth tobacco addiction and cessation, with a focus on e-cigarette cessation. In response to a previous request for similar information, we appeared at the January 18, 2019 public hearing and submitted comments dated February 1, 2019, which we attach and incorporate herein.[1] 


            In the four months since we submitted our written comments, evidence has continued to rapidly accumulate that e-cigarettes are designed to and successfully do attract and addict youth to nicotine products, but no new strategies to address this youth epidemic have emerged.  “Juuling” has become a crisis in schools, with teachers and school administrators spending time monitoring bathroom use instead of focusing on teaching academic curricula, and there is no sign that the epidemic is abating. FDA should use its existing authority to aggressively enforce against companies using marketing strategies designed to appeal to youth, create new youth customers, and keep youth addicted to nicotine.


  1. FDA should prohibit e-cigarette design features that maximize addiction potential and appeal to youth


Bluetooth-enabled or other technologies have the potential to allow manufacturers to customize the dose, speed of delivery, and frequency of use of nicotine to maximize the additive potential for individual users.[2] For example, some devices (e.g., IQOS) have features that allow the device to communicate with the manufacturer that would automatically remind consumers to use the device and to reorder nicotine liquids or pods. Juul’s chief executive Kevin Burns said Juul will soon be testing new Bluetooth technology that will let users monitor on their smartphones how many puffs they are taking and will allow Juul to have “a much more intimate relationship” with customers and help “coach” them to manage their nicotine intake.[3]  This kind of technology featuring two-way communication raises significant privacy as well as health concerns.  It has the potential to allow IQOS, Juul, and other e-cigarette companies to manipulate nicotine delivery in a way that would increase abuse potential and maximize nicotine addiction (while at the same time also maximizing product sales). FDA should prohibit these kinds of technologies and two-way communications in e-cigarettes and other new tobacco products.


FDA’s April 30, 2019 issuance of a marketing order[4] permitting Philip Morris International (PMI) to market its IQOS heated tobacco product in the United States is disconcerting because the IQOS device contains Bluetooth technology that allows PMI to monitor consumers’ puffing behavior and remind them to purchase more nicotine Heatsticks.[5]  FDA’s failure to even mention this issue should be corrected by amending the IQOS marketing order to prohibit two-way communication between the IQOS and PMI or any other party.


In addition to technological design features in devices that could create and maintain nicotine addiction in youth, the physical design of some products are especially attractive to youth and could encourage youth and other non-users to initiate with e-cigarettes and become addicted to nicotine. 


For example, the “tech appeal” of pod devices and in particular the slick design of Juul that resembles USB memory sticks and other user-friendly personal electronics could encourage uptake among young people.[6]  Additionally, because the pod devices are discrete, portable, and create discreet clouds of aerosol, they are convenient and lend themselves to inconspicuous use in places where tobacco use is generally prohibited.6 Moreover, the pod devices may reduce the social stigma previously associated with conventional cigarettes and with earlier generation large “box mod” devices.6 Error! Bookmark not defined. Because these devices are associated with personal electronic devices instead of with tobacco products that are deadly and stigmatized, and are supported by aggressive social media advertising, use of these products have become normalized.6  


Moreover, the Bluetooth, chip, and other electronic features that have been added to e-cigarettes and other new tobacco products have exacerbated environmental concerns. Burgeoning e-cigarette use is creating problems with disposal of hazardous waste in addition to health problems related to tobacco use and nicotine addiction.



  1. FDA should regulate social media advertising by tobacco companies


A May 10, 2019 investigative report by Reuters[7] exposed how PMI aggressively marketed their IQOS heated tobacco product on Instagram and other social media platforms,[8] reaching millions of young people across the globe. This report “demonstrates Philip Morris’ utter lack of sincerity when they promise to market IQOS only to existing smokers and not to youth and nonsmokers – a promise the FDA relied on when it recently authorized the sale of IQOS in the United States.”[9] FDA must put teeth behind marketing restrictions to ensure that PMI and other e-cigarette companies do not use similar strategies to market their products to kids by prohibiting any use of social media influencers.


  1. FDA should halt Juul’s “Switch” campaign because it has high potential to confuse youth and makes unauthorized cessation and modified risk claims


On their face, the ads and testimonials on Juul’s website violate the FDA rules requiring a company to receive FDA authorization from its drug/device authorities before marketing its products for cessation or other "therapeutic" purposes. However, Juul seems to be taking advantage of some murky language in the preamble to FDA's final rule on what it considers the "intended use" of a tobacco product.[10]  However, that imprecise language (in particular, the "switching" language at 82 FR 2193, 2214) must be read in the context of the rest of the rule. Looking at the plain meaning of the words and common sense understanding, "switching" and "smoking cessation" are interchangeable notions that both communicate the same thing to their audience: Juul will help you quit smoking. FDA should immediately clamp down on unauthorized cessation and modified risk claims being made by Juul and other e-cigarette companies.


Importantly, the final rule clearly states that claims made by companies that their product cures or treats nicotine addiction, helps prevent relapse by treating nicotine craving, or provides nicotine addiction relief are all therapeutic claims that would require FDA approval as a drug or device. The language of the final rule itself at section 21 CFR 1100.5(a) says a tobacco product will be subject to regulation as a drug, device, or combination product if the intended use is for "the cure or treatment of nicotine addiction (e.g., smoking cessation), relapse prevention, or relief of nicotine withdrawal symptoms”, and FDA explains in the preamble to the final rule that a claim that a product could be used to “wean yourself off of nicotine” would also suggest that its intended use is as a drug or device.[11] FDA provides some examples "for purposes of illustration," but explicitly states that this is not an exhaustive list. (see 82 FR at p. 2205 and footnote 14). Many of the testimonials on Juul’s website talk about how customers use Juul to get their "nicotine fix," and this seems to fit under that category. See also discussion about Comment 23 at 82 FR p. 2211.


At the very least, these claims are confusing. FDA's says it has "skepticism" about claims that could confuse consumers into believing FDA approves the product for therapeutic uses. FDA said in the final rule preamble, "Where products making claims related to quitting smoking also attempt to disclaim that use in some way, FDA intends to view such disclaimers skeptically because of the likelihood of consumer confusion." This language is repeated at 82 FR at p. 2199, 2203, and 2212.


Of particular and timely concern, FDA stated that "unsubstantiated cessation claims that reach adolescents may confuse teens and lead teens to believe that these products are FDA­approved smoking cessation products." 82 FR at 2212. Many of these issues were raised in a lawsuit recently filed on behalf of the parents of a 15-year-old girl who became addicted to Juul in part because she was confused and misled by Juul’s marketing campaign.[12]


Finally, Juul's stated mission is to "improve the lives" of the world's billion adult smokers. Because the law prohibits Juul from making unsubstantiated health claims, it is indisputable that Juul would not be permitted to state that its product “improves the health” of smokers. We are skeptical that there is a plausible difference between "improving the lives" of smokers and "improving the health" of smokers. Juul may argue that they only mean that their company is "improving the lives of smokers" by giving them a product that doesn't smell as bad, thereby putting Juul in the “non­therapeutic” category. But that kind of claim would hardly be credible, especially since Juul's founders Adam Bowen and James Monsees, who were both longtime smokers, originally said they started experimenting with vaping technology to help themselves and other adults quit smoking.[13]


The FDA has the responsibility and authority to take enforcement action to require Juul to stop running the ads with unsubstantiated cessation and modified risk claims unless and until Juul gets authorization under FDA’s drug/device authorities to market its products as cessation or therapeutic aids, or authorization under FDA’s tobacco authorities to market them with modified risk tobacco product (MRTP) claims. In the United States, companies are prohibited from marketing products with unsubstantiated health claims.  We discussed this issue in our public comment submitted to Docket No. FDA-2019-D-0661on March 21, 2019, which we attach and incorporate herein.[14]


  1. Strong evidence shows flavors attract youth to initiate with and continue using tobacco products and there is not good evidence supporting industry claims that flavors are necessary to help adults quit smoking


In order to attract young and new users, the tobacco industry adds characterizing flavors like mint, menthol, fruit, and candy to tobacco, often using the same flavorants that are in fruit-flavored candy, and sometimes at higher doses.[15] These flavors appeal to new users by masking the harsh taste of tobacco, and in the case of e-cigarettes, resulting in a more pleasant smell than that found with tobacco alone.


Flavor or “taste” is one of the most common persuasive marketing techniques used to promote food (mostly candy and snacks) to children on TV.[16] Exposure to ads for flavored products is positively associated with youth consumption,[17] and most money spent by youth is on food or beverages, particularly sweets.[18] Research on e-cigarettes is consistent with these findings, concluding: flavors play an important role for online e-cigarette marketing and boosts user interaction and positive emotion;[19] flavored (vs. unflavored) e-cigarette ads elicit greater appeal and interest in buying and trying e-cigarettes; and the appeal of ads marketing flavors is linked to rapid and persistent adoption of e-cigarettes among youth.[20]

Youth are Attracted to Flavored Tobacco Products

The vast majority of youth in the US who try tobacco initiate with flavored tobacco products, including 81% of e-cigarette ever users, 65% of cigar ever users, and 50% of cigarette ever smokers.[21] Adolescents are more likely to report interest in trying an e-cigarette from a friend if it is menthol-, candy-, or fruit-flavored than if unflavored.[22] Flavor preferences are associated with higher e-cigarette use among adolescents.[23] Most adolescent current tobacco users cite flavors as a reason for use (including 81% for past 30-day e-cigarette users; 74% for past 30-day cigar users).10 Three quarters of adolescent and young adult flavored tobacco product users reported they would quit if flavors were unavailable.[24]

Youth and young adult tobacco users are more likely than older adult tobacco users to use flavored products, including menthol cigarettes,[25] flavored smokeless tobacco,[26] and flavored cigars.[27] Young smokers (12-17 years of age) are three times as likely to smoke menthol cigarettes than smokers 35 years and older.[28]  Research among approximately 4000 school-going youth shows that for 98% of them, first e-cigarettes used were flavored to taste like something other than tobacco, compared to 44.1% of older adults nationwide. Fruit and candy flavors predominated for all groups; and, for youth, flavors were an especially salient reason to use e-cigarettes.[29] Finally, a recent study showed that only 1.5% of adolescent and young adult e-cigarette users used tobacco flavored-Juuls and .9% used tobacco-flavored other e-cigarette products.  Instead, the majority used fruit or dessert flavors (33% for Juul users and 64% for other e-cigarette users) and 27% of Juul users and 12% of other e-cigarette users used mint or menthol flavors.[30]

Youth Believe Ads for Flavored E-cigarettes Target Them


Using flavors in e-cigarettes is a key marketing strategy to reach and recruit youth. In 2014, over 7,700 flavors for e-cigarettes were available, with greater than 240 new flavors being added per month.[31] What is most important is that youth believe flavored e-cigarette ads target them.

            In a study[32] of California youth and young adults (mean age 17.5, SD = 1.7), participants were asked to indicate whether eight different ads for flavored e-cigarette products (Figure 2), randomly displayed, target someone younger than them, their age, someone a little older, or someone much older like their parents. Participants felt the ads were for someone just a little older than them (age 18 – 26; not for someone much older). More than half of participants felt ads for cherry, vanilla cupcake, caramel, and smoothie flavors were for someone their age. Ads were also seen as targeting an audience younger than them. These findings suggest that while the tobacco industry argues that flavored tobacco products, including sweet and fruit flavored products, are not meant to attract youth, youth see them as aimed at them.
