Tobacco, nicotine and related products have and continue to change rapidly, creating new challenges for policies regulating their advertising, promotion, sponsorship and sales. This paper reviews recent commercial product offerings and the regulatory challenges associated with them. This includes electronic nicotine delivery systems, electronic non-nicotine delivery systems, personal vaporisers, heated tobacco products, nicotine salts, tobacco-free nicotine products, other nicotine products resembling nicotine replacement therapies, and various vitamin and cannabis products that share delivery devices or marketing channels with tobacco products. There is substantial variation in the availability of these tobacco, nicotine, vaporised, and related products globally, and policies regulating these products also vary substantially between countries. Many of these products avoid regulation by exploiting loopholes in the definition of tobacco or nicotine products, or by occupying a regulatory grey area where authority is unclear. These challenges will increase as the tobacco industry continues to diversify its product portfolio, and weaponises ‘tobacco harm reduction’ rhetoric to undermine policies limiting marketing, promotion and taxation of tobacco, nicotine and related products. Tobacco control policy often lags behind the evolution of the industry, which may continue to sell these products for years while regulations are established, refined or enforced. Policies that anticipate commercial tobacco, nicotine and related product and marketing changes and that are broad enough to cover these product developments are needed.

The landscape of commercial tobacco, nicotine and related products has changed substantially over the past 30 years, accelerating in the past decade. While cigarettes continue to be the dominant form of tobacco use, the number, variety and uptake of more recently developed products are increasing,1 particularly among youth.2 Youth uptake of nicotine and other vaporised products may sustain nicotine addiction or lead to smoking and other substance initiation.3–5 An enormous number and variety of electronic nicotine delivery products are in the market, with nearly 16 000 flavours available,6 and global sales rising to US$15 billion in 2019.1 7 Heated tobacco products (HTPs) were also available in over 50 markets worldwide in 2020.7 The continued introduction of such products creates challenges for marketing policy and regulation.8 9 This paper reviews examples of commercial tobacco, nicotine, and other related products introduced or marketed more aggressively in the past decade and highlights features in their advertising, promotion, sponsorship and sales that create challenges for tobacco control policy, in order to identify evolving needs for effective policy addressing these products’ marketing. While examples herein highlight marketing activities or challenges faced in specific countries, they reflect broader issues likely to be found elsewhere in the world.
Electronic nicotine delivery systems
The 2021 WHO report on the global tobacco epidemic included a call to address ‘new and emerging tobacco products’.1 Electronic nicotine delivery systems (ENDS) and electronic non-nicotine delivery systems (ENNDS)10 11 are subject to different regulatory policies around the world: as of 2020, ENDS/ENNDS sales are banned in 32 countries, and advertising and promotion of ENDS/ENNDS is prohibited completely or partially in 75 countries.1 12 Many countries limit age of purchase, require licensing as medicines, limit public use, or limit nicotine concentrations, ingredients or flavours.1 13 The policies and regulations on combustible tobacco products are reviewed elsewhere in this issue.14 The introduction of new ENDS/ENNDS products and features has typically been faster than regulations can be developed, and the market and advertising continue to evolve rapidly.6 15 Variability in size, efficiency, power, heating materials and liquids creates challenges for regulation. For example, ‘pod vape’-style ENDS like the JUUL-branded devices typically have high levels of nicotine. Following European Union 2016 regulations limiting nicotine content to 20 mg/mL in ENDS liquids,16 in 2019 JUUL released products that increased nicotine delivery by over 50% by changing their wick designs rather than increasing nicotine content in the liquid.17 In addition to nicotine, the solvents and flavours present in the liquids in ENDS/ENNDS may have toxicity warranting regulation.18–20 Most flavours in ENDS/ENNDS are food additives that were not safety tested for heating and inhalation.21 22 More recently, while some ENDS marketing applications have been denied in the USA,23 millions of ENDS/ENNDS products are already being sold,24 and it is unknown how to efficiently or effectively stem the tide.
Enforcement of regulations and advertising control policies is a global challenge. For example, although sales and imports of all ENDS products are banned in Thailand,25 they are sold illegally via online platforms.26–28 The same is true in Brazil, where marketing, advertising and importation of ENDS are not allowed, but they are sold illegally at vape shops, tobacco stores, on the internet and by using delivery apps.29 30 In South Africa, ENDS are to be sold only by prescription, but they are widely advertised as smoking cessation products and sold without prescription.31 Policies narrowly applied to specific types of ENDS are easily circumvented by making small modifications; in the USA when the Food and Drug Administration (FDA) announced it would prioritise enforcement of flavour bans in reusable pod ENDS, disposable ENDS exploited this loophole, and high school student use of disposable ENDS increased from 2.4% in 2019 to 26.5% in 2020.32 Similarly, since the 2017 Tobacco Business Act in South Korea defined tobacco as a product ‘manufactured in a state suitable for smoking, sucking, inhaling steam, chewing or smelling, by using tobacco leaves as all or any part of the raw materials’,33 some ENDS manufacturers introduced liquids for inhalation with nicotine derived from the stem or root of the tobacco plant to circumvent these regulations. ENNDS products with added vitamins, nutrients and herbal supplements may be perceived as healthy without scientific evidence of health benefit,34 and it may not be clear if they can be regulated as tobacco products. Indeed, vitamin ENNDS may be promoted as nicotine free to imply health benefits.
Heated tobacco products
The popularity of ENDS/ENNDS opened market opportunities for HTPs, which contain tobacco heated to temperatures short of combustion to produce tobacco smoke for inhalation.35 Previous heated cigarette products failed due to poor acceptability and inability to deliver on promises of eliminating secondhand smoke,36 but over time devices have become smaller, cheaper and more convenient, and consumers using ENDS are more likely to try HTPs.37 38 Newer generations of HTPs launched in Japan in 201439; in 2021 Japan had the highest number of HTP users in the world40 with Philip Morris International’s (PMI) IQOS leading the market.41 42 HTPs are more likely to be used by younger adults43 and people with higher income.44 There is variability in policies regulating HTPs: some countries completely ban sales or import, while others include HTPs under tobacco regulations.45 In South Africa, HTPs are subject to the same regulations as cigarettes, but since many HTPs resemble ENDS, which are not regulated as tobacco products, regulating HTP is challenging. In Thailand where HTPs are banned,46 the products are sold illegally.26 47 In Japan and Korea, there are more strict limitations on ENDS and fewer restrictions on HTP advertising than cigarettes, which has resulted in aggressive promotion of HTPs which now occupy 14.3% of the total tobacco market in Korea and 30% in Japan.48 In 2020 in Japan, 53% of tobacco advertisements in newspapers and 94% of tobacco advertisements in magazines promoted HTPs.49 In Korea, HTP devices were considered to be electronics rather than tobacco products50 so HTPs have been advertised with lifestyle appeals, including a 2019 British American Tobacco (BAT) social media campaign featuring hip hop musicians popular among youth.50 51 The music video avoided age restrictions because it included images of the heating devices but not the tobacco pods, accruing more than a million views.51 In Germany, the ‘neo glo’ (BAT) HTP features a ‘boost’ feature which gives an extra strong hit of nicotine, and an ‘ergonomic’ and colourful closed system design.52 BAT’s HTPs have ‘gained share in all key markets’ in 2021.53
Some tobacco companies aimed to promote HTP products as reduced harm.36 The US FDA authorised PMI to make an ‘exposure modification’ but not a ‘risk modification’ claim for IQOS in 2020.54 While the FDA regulates only US tobacco products, many other countries rely on FDA for guidance on how to regulate recently developed products.55 The FDA exposure modification authorisation was used to promote IQOS sales as a safer tobacco product in other countries.56 In Thailand, ENDS advocates advertised that the FDA had found IQOS ‘appropriate for the protection of the public health’.25 In Korea, where relative risk claims are allowed as long as the claim does not deceive customers, IQOS was promoted, using a ‘Science Machine’ resembling a now defunct smoking machine57 that collected cigarette smoke and HTP smoke on filter paper to show that HTPs produced fewer residuals than a cigarette.58 59 Smoking machine yields were intentionally misrepresented by tobacco companies in the past to mislead the public by implying low-tar cigarettes were healthier.57 In Japan, reduced risk claims,60 exceptions for HTPs in smoke-free policies, and social acceptability all contribute to HTP popularity.61 In Canada, HTP devices and tobacco sticks were sold without graphic warning labels.62
PMI and ENDS advocacy groups used reduced risk messaging on websites and social media to pressure the government to lift the ENDS ban in Thailand.25 Similarly, in South Africa, tobacco harm reduction claims were used by ENDS manufactures, to challenge efforts to regulate ENDS,56 63 and in Brazil the National Regulatory Agency has been pressured by ENDS advocates and PMI to lift the ban on ENDS and HTPs using harm reduction arguments in public comment64 and on social media.65 66
Pairing tobacco products with other consumer goods
New ENDS/ENNDS features will continue to emerge with unclear regulatory authority. For example, products with personal electronic features, such as connections to apps,67 voice-controlled cloud-based technology like Amazon’s Alexa,68 or Bluetooth speakers,69 have appeared in US markets. Bluetooth and smartphone apps that connect to vape devices have been proposed for entertainment and age enforcement (eg, detection of devices in schools)70–72; these features may also allow manufacturers to track and monitor users passively. Korean IQOS’ Bluetooth technology can record battery level and usage, and a third-party app uses the information to track number of tobacco sticks smoked per day, as well as the days and times IQOS is used most.73 JUUL has produced devices in the UK and Canada with Bluetooth connected to a phone app to allow tracking of vape consumption claiming utility to prevent youth use,70 71 74 and JUUL continued to file patent applications for ‘smart’ ENDS in 2020.75 HTPs that resemble personal electronic devices may appear to be safer due to perceived technological advancement or because they share the familiar ubiquity of electronic devices in everyday life. Differentiation from cigarettes and association with personal electronics may be advantageous in markets where cigarette smoking is denormalised.76 Other accessories such as lanyards and holders share a ‘friendly familiarity’ with other consumer products and may not be included in definitions of tobacco products, making them difficult to regulate. ENDS/ENNDS that resemble speakers, watches or lipsticks may be difficult to recognise, creating a challenge for policy enforcement.
In addition to electronics, flavoured ‘add-ons’ pose a regulatory challenge. Cigarettes with flavoured capsules are popular in Europe, Africa, Latin America and Asia, and flavoured cigarette bans may not include capsules.77 In Brazil, while tobacco additives are prohibited, due to numerous lawsuits, the regulatory measure is still not fully implemented, and flavoured capsules continue to be sold. There is pressure to allow flavoured additives in ENDS as influencers claim the flavours are essential for smoking cessation. As FDA began to enforce eliminating some flavoured ENDS, ‘Puff Krush’ silicone caps containing flavour capsules designed to fit on pod vape devices appeared in the USA (figure 1)78; separate flavour cards and menthol drops were sold in Canada following the menthol ban.79 In Thailand, crushable flavour beads are sold for insertion in cigarettes (figure 1), but pose a regulatory challenge as they are sold separately from tobacco products and also promoted for other uses, such as adding to COVID-19 pandemic face masks to improve bad breath.80–82
Nicotine salt liquids (also called ‘Salt Nic’) with organic acids added to enhance appeal and sensory experience have become widely used in ENDS.83 Nicotine salt liquids dramatically increased nicotine content and efficiency of nicotine delivery.84 In addition to higher nicotine content, US products are available in large sizes with 3000–4000 puffs, 8–12 mL liquid.85 86 Nicotine salts are also offered in nicotine pouches, which resemble and are used similarly to oral tobacco products like Swedish snus, but instead of tobacco leaf contain nicotine, flavourants and binders in a porous pouch.87 Nicotine salts are perceived by consumers to be an innovation, an improvement, better tasting and better quality.16 83 88 While high-nicotine content may encourage users to switch away from cigarettes or to consume less liquid thus decreasing exposure to toxicants,89 it may also facilitate youth nicotine addiction.84 The marketing of these products drives who adopts the product and whether the use pattern is beneficial for population health. In the USA, ENDS with nicotine salts became rapidly popular among youth, first with marketing of JUUL brand devices,90 and continued marketing and promotion of disposables such as Puff Bar.91 Youth use of ENDS led to the net result of more population harm than benefit.92
Nicotine gum, lozenge and pouch products
In recent years, some tobacco companies have started to sell nicotine gum, lozenges and pouches without claims to be nicotine replacement therapies (NRTs).93 Nicotine gum and pouches sold in convenience stores may attract consumers to use nicotine for purposes other than smoking cessation. The Lucy brand in the USA sells nicotine gum (pomegranate, spearmint) and nicotine lozenges (cherry ice, citrus, mint), and pouches (spearmint, mango, cool cider) in flavours more appealing than approved NRTs. The Lucy website states its lozenge products are FDA approved for smoking cessation, while the gum is not; the website claims the gum contains a different ‘unique nicotine resinate’ with greater bioavailability.94 Nicotine salt pouch products (eg, On, Dryft, Zyn) were introduced in the USA in 2016, followed by Rogue in 2018, and sales increased exponentially since their introduction.87 Nicotine pouches are made or distributed by the major tobacco companies in the USA and these products are not approved for smoking cessation; they feature a wider variety of flavours (eg, mango, cinnamon, honey lemon, black cherry, mint) and higher levels of nicotine than NRTs.87 In addition, products are converging under the same brand names. RJR Vapor’s nicotine lozenge (Revel) was subsequently rebranded with its pouch brand name, Velo.95 RJR’s parent company, BAT, announced in 2020 that it would be building a first of its kind factory in Kenya to manufacture nicotine pouches,96 and planned to expand sales of Velo nicotine pouches in Indonesia in 2021.97 Rogue nicotine includes pouches, gum and lozenges under a single brand.98 Consolidating different nicotine products under the same brand name may confuse consumers and give the unapproved products the appearance of FDA approval.
‘Tobacco-free nicotine’: synthetic nicotine
Some nicotine pouches, gum and ENDS claim they contain synthetic nicotine, exploiting another regulatory gap in the USA, falling outside of the definition of tobacco product by the Federal Food Drug and Cosmetic’s Act.99 After FDA orders to remove their flavoured disposable ENDS from the market in 2020,100 the makers of Puff Bar announced in early 2021 they were returning to market with ‘tobacco-free nicotine’ products.101 102 In 2021, at least seven new tobacco-free nicotine pouches have been introduced in the US market (2ONE, NIIN, Rush, Fre, FR3SH, Bidi, Lucy). Two brands, 2ONE and NIIN, advertise the use of TFN, a trademarked ‘tobacco-free’, synthetic nicotine.103 Lucy ‘kapsel pouches’ contain 8 mg of nicotine, double that of other Lucy nicotine products, and claim to contain tobacco-free nicotine unlike Lucy gum and lozenges. An April 2021, search on ENDS retailer websites in the USA found numerous brands of tobacco-free nicotine liquids and disposable pod vaping devices, including both freebase and nicotine salt formulations.104 Some products labelled ‘tobacco-free nicotine’ claim to contain synthetically produced nicotine and others state the nicotine is derived from tobacco but purified. Tobacco plants produce only one of the two chemical enantiomers of nicotine (S-nicotine), while synthetic nicotine is commonly a racemic 50:50 mixture of the two chemical enantiomers (S-nicotine and R-nicotine).105 Little is known about the R-nicotine enantiomer because previously human exposure to and intake of R-nicotine was minimal105; the substantial presence of R-nicotine in synthetic nicotine products has unknown health impact.9
FDA has not made a decision about how it may regulate synthetic nicotine products,101 exemplifying how a regulatory agency may lag behind the commercial market, constrained by outdated and narrow legislation. News reports in 2021 stated the Japanese health ministry will regulate tobacco-free nicotine pouches as pharmaceutical products.106 In some parts of Africa, BAT’s Lyft nicotine pouches are being marketed as ‘modern oral nicotine pouch without tobacco’, causing regulatory confusion as most tobacco laws do not cover nicotine products. As policies in Africa are reviewed to add ENDS regulations, smokeless nicotine products should also be addressed. Similar to ENDS arguments described above, the tobacco industry pushed back on regulation based on harm reduction claims.107 108 Perhaps because they occupy a regulatory loophole, tobacco-free nicotine products are available on the internet from the online retailer Amazon, which prohibits selling tobacco products and ENDS in the USA. Tobacco-free nicotine products may appear to be regulated; some have invented a warning label which appears similar to the US federal nicotine warning labels, but includes the terms, ‘tobacco-free nicotine’109 or ‘non-tobacco nicotine’110 (figure 2).
The use of the term ‘pharmaceutical grade’ nicotine94 to describe recently developed nicotine products and the acquisition of NRTs extends the tobacco industry’s embrace of pharmaceuticalisation —producing products that appear like medical therapeutics conferring perceptions of safety.111 A recent and heavily criticised example of pharmaceuticalisation was PMI’s September 2021 takeover of the UK pharmaceutical company Vectura, which produces inhaled medications, an act that prompted protest from the medical community calling it ‘deeply disturbing and perverse’ that a tobacco company would profit from treatment of the lung diseases caused by its products.112 The purchase is consistent with tobacco industry plans to move into cannabis, botanicals and respiratory drug delivery as part of their ‘beyond nicotine’ strategy to offer a variety of different products that offer consumers ‘sensorial enjoyment for different moods and moments’.113 114 In addition to the diversified tobacco industry, a host of other companies are entering the market, producing similar nicotine and vaporised products, including counterfeit products, which raise further regulatory challenges.
Tobacco and cannabis product convergence
Tobacco and cannabis co-use is common, particularly among young people.115–118 In the USA, tobacco companies considered entering the cannabis market in the 1960s, but did not do so due to the federal legal status.119 Cannabis legalisation in many US states facilitates development of new smoked products. TAAT hemp cigarettes offering a ‘nicotine and tobacco-free smoking experience’ were introduced in the USA in 2021 by a company led by former PMI executives.120 Tobacco and cannabis products may be lumped together for consumers: online ‘product reviews’ for ENDS/ENNDS, HTPs and cannabis vaporisers frequently appear alongside each other on the same websites.121 The popularity of ENDS in the USA was followed by an increase in cannabis vaping among young people, and a proliferation of illicit cannabis vapes that contributed to the outbreak of vaping-associated lung disease.122 Vitamin and CBD ENNDS are also likely to be sold in the same space and circumstances as tobacco products but may not be subject to tobacco regulation. Vitamin ENNDS were promoted as a smoking cessation aid in Korea in 2016123 and were described on the US market in 2018.34 CBD products were commonly found in US online vape shops in 2021.124
Recently developed tobacco, nicotine and other vaporised products are continuing to enter markets with aggressive promotion both in high-income countries where cigarette smoking is declining and where consumers can afford expensive new products, as well as in lower and middle-income countries, circumventing policies banning tobacco advertising or ENDS imports. Attention and debate about ENDS/ENNDS and related products may serve to distract or deter policymakers from an appropriate focus on cigarette smoking. The embrace of tobacco harm reduction may allow tobacco and ENDS companies to reposition themselves as partners in public health, which contradicts the Framework Convention on Tobacco Control Article 5.3 and allows the industry to undermine tobacco control.107 The tobacco industry continues to use harm reduction arguments to argue against bans on ENDS and recently developed products, taxation of new products, and to push for medical authorisation of nicotine products which might later lead to subsidy of the nicotine products for smoking cessation.64 125 Finally, as the industry continues to reinvent itself to stay in business, regulatory authorities mostly play ‘catch up’. Current strategies which give the industry ample time to market products while they are brought under regulatory frameworks are not helpful for public health. The new product and marketing landscape highlights the need to update measures once considered tobacco control staples (eg, advertising bans, which have to some extent been overtaken and rendered out of date by new online promotional methods) to address marketing of ENDS/ENNDS and other recently developed nicotine and vaporised products. Policies that anticipate changes to products and that ensure regulatory provisions are broad enough to accommodate future potential products will save time, money and lives.
What this paper adds
Few studies address the variety of recently introduced tobacco, nicotine, and related products, and how product diversification is used to undermine tobacco control policies.
This paper details how commercial entities tweak product specifications to circumvent current regulations (and often continue updating their products to stay one step ahead of evolving regulations) to maximize rapid sales that outpace policy development and implementation.
Escalating numbers of product variants are a worldwide trend in mature tobacco markets, legitimised explicitly or implicitly as reduced harm without supporting scientific evidence, leveraging perceptions of safety and technological advancement to recruit new generations of tobacco and nicotine addicts.
The tobacco industry deploys harm reduction arguments to circumvent the Framework Convention on Tobacco Control's Article 5.3, to argue against bans on ENDS and recently developed products, pressure against taxation of new products, and to push for medical authorization of nicotine products.
