List of heat-not-burn products

A wide variety of new tobacco- and smoking-related products have emerged on the market in recent years, as of 2018.[1] Moreover, tobacco companies will keep developing new products to keep meeting the changing needs of their consumers and fulfill changing regulatory requirements.[1] These tobacco-related products can quickly gain popularity, even before there is sufficient scientific evidence to determine their effects on the user and bystander.[1] For instance, recently products marketed as "harm reduction," "reduced risk," or "next generation" products were introduced making claims of being up to 90% less harmful than traditional cigarettes, as of 2018.[1] Even though these products seem very attractive to consumers, independent scientific research to support these claims is lacking.[1] In addition, these products may be attractive for smokers, but may also be used by non-smokers.[1] Besides, regardless of their own harmfulness, popular new products could also serve as a gateway to the use of tobacco or tobacco-related products.[1]

According to a 2018 report, given their potential harmful health effects, and the possibility that these products serve as a gateway to the use of more harmful products, it is important for national authorities and scientists to closely monitor product development of new tobacco and tobacco-related products.[1] Data on product development, marketing strategies, and consumer interest in new products could help to understand potential implications for public health and guide tobacco control efforts.[1] The World Health Organization recognizes the importance of monitoring the availability and regulation of new tobacco and tobacco-related products entering national and global markets.[1]

The tobacco control community is still deciding how to address the unexpected rise in popularity of e-cigarettes.[7] However, there is another product innovation already emerging: Heat-not-burn tobacco products.[7] These products are being introduced in markets around the world by tobacco companies seeking to appeal to consumers who still demand the "throat-hit" delivered by traditional cigarettes but not by e-cigarettes.[7]

Japan has been the focal market to test the potential of heat-not-burn as a cigarette alternative, where manufacturers have marketed several heat-not-burn brands nationwide, including Japan Tobacco's "Ploom TECH" device in March 2016, Philip Morris International"s "iQOS" device in April 2016, and British American Tobacco’s "glo" device in December 2016.[7] As of 2017, tobacco industry leaders have predicted heat-not-burn products are poised to further displace traditional cigarette smoking and, by extension, tobacco control strategies typically framed around traditional cigarettes.[7]

A regular cigarette consists primarily of tobacco leaves wrapped in cigarette paper.[8] It may also contain a filter, chemical additives, or other components.[8] The user lights the tip of the cigarette to burn the tobacco and inhales the smoke through the unlit end.[8]

A heat-not-burn product consists of a heating source and tobacco.[8] The tobacco may be wrapped in paper, which makes it a type of cigarette.[8] However, the tobacco is heated to a lower temperature than a combusted cigarette to create an aerosol that the user inhales.[8]

An electronic cigarette uses an e-liquid that may contain nicotine (typically derived from the tobacco plant), glycerin, propylene glycol, flavorings, and other ingredients.[8] The device has an electric heat source that heats the e-liquid to create an aerosol that the user inhales.[8]

Three components of a heat-not-burn type product.[9]

There are two types of heat-not-burn products currently allowed to be sold in the US, as of 2019.[8] One product type, which has been on the US market at various times since the 1990s, uses a carbon tip wrapped in glass fibers.[8] The user lights the carbon tip, which heats the dried tobacco inside to a temperature that does not cause the product to create ash or burn down in size.[8]

Another heat-not-burn product called IQOS[10] that recently obtained US Food and Drug Administration (US FDA} authorization in April 2019 consists of an electronic heating device and sticks made from dried tobacco wrapped in paper.[8] The user places the stick into the electronic heating device, which pierces the stick with a glass-covered ceramic blade that heats the tobacco, creating an aerosol.[8]

There are a variety of products colloquially called heated tobacco products and heat-not-burn products that do not appear to fit easily into universally agreed upon product categories.[8] Products currently sold in global markets may function in various ways.[8] For example, these products heat to various temperatures, can contain dry, moist, or liquid tobacco ingredients, and appear in a wide variety of shapes.[8]

For the US FDA's purposes, if a tobacco product meets the legal definition of a cigarette but the tobacco is not heated to a temperature high enough to cause combustion, the product would be currently categorized as a non-combusted cigarette and regulated as a cigarette.[8] As of 2019, the types of heated tobacco products currently authorized for sale in the US are all non-combusted cigarettes.[8]
