Composition of heated tobacco product emissions

Last updated • 4 min readFrom Wikipedia, The Free Encyclopedia

The composition of the emissions generated from heated tobacco products are generally lower than that found in cigarette smoke. [1] This is due to the comparatively low temperatures, the filter systems, and physical design. [1] The composition of what is produced is complex. [2] The main toxicants found in the emissions of cigarette smoke (i.e., tar, nicotine, carbonyl compounds, and nitrosamines) are also found in the emissions of these products in varying concentrations. [3] The aerosol generated contains levels of nicotine and cancer-causing chemicals that are comparable to regular cigarettes. [4] The emissions contained 84% of the nicotine found in regular cigarettes. [5]

The available research on the mainstream and exhaled aerosol generated by these products is limited, as of 2018. [6] They do not generate side-stream emissions. [6] The exhaled aerosol is highly volatile because it is made up of liquid particles that evaporate quickly. [6] The particle size of their emissions have a median aerodynamic diameter that is somewhat bigger than those found in cigarette smoke. [2] There is a lack of agreement on the composition of the emissions in the documented literature, as of 2018. [7] These products, however, still pose health risks. [1] Lower levels of harmful emissions has been shown, but lowering the risk to the smoker who transitions to using them has not been shown, as of 2018. [2] As a result of the various types of heated tobacco products, the characteristics and effects for each type will be different. [8]

Since the 1960s heated tobacco products were in development by tobacco companies. [9] Safer heated tobacco products that deliver nicotine but limit emissions of tar or carbon monoxide (CO) is a half-century old idea, which had been unsuccessfully market-tested since 1988, first as Premier by the RJ Reynolds Tobacco Company (RJR) and later as Eclipse (RJR) and Accord Philip Morris International (PMI). [10] Various heated products were reintroduced to the market, as of 2018. [11]

Introduction

Heated tobacco products are electronic devices that heat processed tobacco to supposedly deliver an aerosol with fewer toxicants than in cigarette smoke. [10] Commercially available heated tobacco systems like glo (produced by British American Tobacco (BAT)) or IQOS (Philip Morris International (PMI)) include a charger, a holder and tobacco sticks, plugs or capsules. [10] Inserted into the holder, tobacco sticks are heated with an electronically controlled heating element. [10] Other products, like iFuse from BAT or Ploom Tech from Japan Tobacco (JT), produce aerosol from a non-tobacco source and pass it through a tobacco plug to absorb flavor and nicotine. [10] Heated tobacco products aim for a niche between combustible tobacco smoking and electronic cigarettes that aerosolize nicotine suspended in humectants. [10]

Since the 1960s heated tobacco products were in development by tobacco companies. [9] Safer heated tobacco products that deliver nicotine but limit emissions of tar or carbon monoxide (CO) is a half-century-old idea, which had been unsuccessfully market-tested since 1988, first as Premier by the RJ Reynolds Tobacco Company (RJR) and later as Eclipse (RJR) and Accord (PMI). [10] As of 2018, various heated tobacco products were reintroduced to the market. [11] Japan, where manufacturers have marketed several heated tobacco brands since 2014, has been the focal national test market, with the intention of developing global marketing strategies. [12] According to a 2018 report, the launching of the latest incarnation of heated tobacco products is a reiteration of similar efforts in the past to use similar products to undermine tobacco control, particularly efforts that present the tobacco industry as a harm reduction partner. [13]

As of 2018, of the current heated tobacco products, IQOS was launched in several cities in Japan, Italy and Switzerland in 2014, iFuse was released in Romania in 2015 and glo and Ploom Tech were introduced to Japanese cities in 2016. [10] Due to regulations restricting the sale of nicotine-containing e-cigarettes, Japan was a fertile market for heated tobacco producers, suggesting that the products have potential 'for explosive global growth'. [10] By 2017, IQOS was available in 30 countries and was being considered by United States Food and Drug Administration for a reduced-risk product approval, and the UK was one of the first countries to assign a separate taxation category for heated tobacco products. [10]

List of substances

Substances emitted exist as gases, [2] liquid droplets, [6] and particulate matter. [8]

Nicotine marketing is the marketing of nicotine-containing products or use. Traditionally, the tobacco industry markets cigarette smoking, but it is increasingly marketing other products, such as electronic cigarettes and heated tobacco products. Products are marketed through social media, stealth marketing, mass media, and sponsorship. Expenditures on nicotine marketing are in the tens of billions a year; in the US alone, spending was over US$1 million per hour in 2016; in 2003, per-capita marketing spending was $290 per adult smoker, or $45 per inhabitant. Nicotine marketing is increasingly regulated; some forms of nicotine advertising are banned in many countries. The World Health Organization recommends a complete tobacco advertising ban.

Smokeless tobacco is a tobacco product that is used by means other than smoking. Their use involves chewing, sniffing, or placing the product between gum and the cheek or lip. Smokeless tobacco products are produced in various forms, such as chewing tobacco, snuff, snus, and dissolvable tobacco products. Smokeless tobacco products typically contain over 3000 constituents. All smokeless tobacco products contain nicotine and are therefore highly addictive. Quitting smokeless tobacco use is as challenging as smoking cessation.

<span class="mw-page-title-main">Electronic cigarette</span> Device that vaporizes a liquid nicotine solution for inhalation

An electronic cigarette or vape is a device that simulates tobacco smoking. It consists of an atomizer, a power source such as a battery, and a container such as a cartridge or tank filled with liquid. Instead of smoke, the user inhales vapor. As such, using an e-cigarette is often called "vaping". The atomizer is a heating element that vaporizes a liquid solution called e-liquid, which quickly cools into an aerosol of tiny droplets, vapor and air. E-cigarettes are activated by taking a puff or pressing a button. Some look like traditional cigarettes, and most kinds are reusable. The vapor mainly comprises propylene glycol and/or glycerin, usually with nicotine and flavoring. Its exact composition varies, and depends on several things including user behavior.

Smoking in South Korea has decreased overall for both men and women in the past decades. However, a high prevalence of tobacco use is still observed, especially with the rise of novel tobacco products like e-cigarettes and heat-not-burn tobacco products. There are socioeconomic inequalities in smoking prevalence according to gender, income, education, and occupational class. Advocates call for measures to reduce the smoking rates and address smoking inequalities using a combination of monitoring and tobacco control policies. These measures include significant price hikes, mandatory warning photos on cigarette packs, advertising bans, financial incentives, medical help for quitting, and complete smoking bans in public places.

The use of electronic cigarettes (vaping) carries health risks. The risk depends on the fluid and varies according to design and user behavior. In the United Kingdom, vaping is considered by some to be around 95% less harmful than tobacco after a controversial landmark review by Public Health England.

<span class="mw-page-title-main">Construction of electronic cigarettes</span> Engineering and chemistry of e-cigarettes

An electronic cigarette is a handheld battery-powered vaporizer that simulates smoking, but without tobacco combustion. E-cigarette components include a mouthpiece, a cartridge, a heating element/atomizer, a microprocessor, a battery, and some of them have an LED light on the end. An atomizer consists of a small heating element, or coil, that vaporizes e-liquid and a wicking material that draws liquid onto the coil. When the user inhales a flow sensor activates the heating element that atomizes the liquid solution; most devices are manually activated by a push-button. The e-liquid reaches a temperature of roughly 100–250 °C (212–482 °F) within a chamber to create an aerosolized vapor. The user inhales an aerosol, which is commonly but inaccurately called vapor, rather than cigarette smoke. Vaping is different from smoking, but there are some similarities, including the hand-to-mouth action of smoking and a vapor that looks like cigarette smoke. The aerosol provides a flavor and feel similar to tobacco smoking. There is a learning curve to use e-cigarettes properly. E-cigarettes are cigarette-shaped, and there are many other variations. E-cigarettes that resemble pens or USB memory sticks are also sold that may be used unobtrusively.

A vape shop is a retail outlet specializing in the selling of vaping products, though shops selling derived psychoactive cannabis products have increased since the passage of the 2018 Farm Bill. There are also online vape shops. A vape shop offers a range of vaping products. The majority of vape shops do not sell vaping products that are from "Big Tobacco" companies. In 2013, online search engine searches on vape shops surpassed searches on e-cigarettes. Around a third of all sales of vaping products take place in vape shops. Big Tobacco believes the independent vape market is a threat to their interests.

A heated tobacco product (HTP) is a tobacco product that heats the tobacco at a lower temperature than conventional cigarettes. These products contain nicotine, which is a highly addictive chemical. The heat generates an aerosol or smoke to be inhaled from the tobacco, which contains nicotine and other chemicals. HTPs may also contain additives not found in tobacco, including flavoring chemicals. HTPs generally heat tobacco to temperatures under 600 °C (1100 °F), a lower temperature than conventional cigarettes.

<span class="mw-page-title-main">Usage of electronic cigarettes</span> Overview about the usage of electronic cigarettes

The usage of electronic cigarettes has risen rapidly since their introduction to the market in 2002. The global number of adult e-cigarettes users rose from about 7 million in 2011 to between 68 million and 82 million in 2021. Awareness and use of e-cigarettes greatly increased over the few years leading up to 2014, particularly among young people and women in some parts of the world. Since their introduction vaping has increased in the majority of high-income countries. E-cigarette use in the US and Europe is higher than in other countries, except for China which has the greatest number of e-cigarette users. Growth in the UK as of January 2018 had reportedly slowed since 2013. The growing frequency of e-cigarette use may be due to heavy promotion in youth-driven media channels, their low cost, and the belief that e-cigarettes are safer than traditional cigarettes, according to a 2016 review. E-cigarette use may also be increasing due to the consensus among several scientific organizations that e-cigarettes are safer compared to combustible tobacco products. E-cigarette use also appears to be increasing at the same time as a rapid decrease in cigarette use in many countries, suggesting that e-cigarettes may be displacing traditional cigarettes.

Exposure to nicotine, from conventional or electronic cigarettes during adolescence can impair the developing human brain. E-cigarette use is recognized as a substantial threat to adolescent behavioral health. The use of tobacco products, no matter what type, is almost always started and established during adolescence when the developing brain is most vulnerable to nicotine addiction. Young people's brains build synapses faster than adult brains. Because addiction is a form of learning, adolescents can get addicted more easily than adults. The nicotine in e-cigarettes can also prime the adolescent brain for addiction to other drugs such as cocaine. Exposure to nicotine and its great risk of developing an addiction, are areas of significant concern.

Electronic cigarettes are marketed to smoking and non-smoking men, women, and children as being safer than cigarettes. E-cigarette businesses have considerably accelerated their marketing spending. All of the large tobacco businesses are engaging in the marketing of e-cigarettes. For the majority of the large tobacco businesses these products are quickly becoming a substantial part of the total advertising spending. E-cigarette businesses have a vested interest in maximizing the number of long-term product users. The entrance of traditional transnational tobacco businesses in the marketing of such products is a serious threat to restricting tobacco use. E-cigarette businesses have been using intensive marketing strategies like those used to publicize traditional cigarettes in the 1950s and 1960s. While advertising of tobacco products is banned in most countries, television and radio e-cigarette advertising in several countries may be indirectly encouraging traditional cigarette use.

Nicotine salts are salts formed from nicotine and an acid. They are found naturally in tobacco leaves. Various acids can be used, leading to different conjugate bases paired with the ammonium form of nicotine.
