Indonesia - Java - Yogyakarta - Cigarette Manufacturing - 37

A cigarette, also known colloquially as a fag in British English, is a narrow cylinder containing psychoactive material, usually tobacco, that is rolled into thin paper for smoking. Most cigarettes contain a "reconstituted tobacco" product known as "sheet", which consists of "recycled [tobacco] stems, stalks, scraps, collected dust, and floor sweepings", to which are added glue, chemicals and fillers; the product is then sprayed with nicotine that was extracted from the tobacco scraps, and shaped into curls. The cigarette is ignited at one end, causing it to smolder; the resulting smoke is orally inhaled via the opposite end. Most modern cigarettes are filtered, although this does not make them safer. Cigarette manufacturers have described cigarettes as a drug administration system for the delivery of nicotine in acceptable and attractive form. Cigarettes are addictive (because of nicotine) and cause cancer, chronic obstructive pulmonary disease, heart disease, and other health problems.

 

The term cigarette, as commonly used, refers to a tobacco cigarette but is sometimes used to refer to other substances, such as a cannabis cigarette. A cigarette is distinguished from a cigar by its usually smaller size, use of processed leaf, and paper wrapping, which is typically white. Cigar wrappers are typically composed of tobacco leaf or paper dipped in tobacco extract.

 

Smoking rates have generally declined in the developed world, but continue to rise in some developing nations. Cigarette smoking causes health harms and death. Nicotine is also highly addictive. About half of cigarette smokers die of tobacco-related disease[9] and lose on average 14 years of life.

 

Cigarette use by pregnant women has also been shown to cause birth defects, including low birth weight, fetal abnormalities, and premature birth. Second-hand smoke from cigarettes causes many of the same health problems as smoking, including cancer, which has led to legislation and policy that has prohibited smoking in many workplaces and public areas. Cigarette smoke contains over 7,000 chemical compounds, including arsenic, formaldehyde, cyanide, lead, nicotine, carbon monoxide, acrolein, and other poisonous substances. Over 70 of these are carcinogenic. Additionally, cigarettes are a frequent source of deadly fires in private homes, which prompted both the European Union and the United States to require cigarettes to be fire-standard compliant.

 

HISTORY

The earliest forms of cigarettes were similar to their predecessor, the cigar. Cigarettes appear to have had antecedents in Mexico and Central America around the 9th century in the form of reeds and smoking tubes. The Maya, and later the Aztecs, smoked tobacco and other psychoactive drugs in religious rituals and frequently depicted priests and deities smoking on pottery and temple engravings. The cigarette and the cigar were the most common methods of smoking in the Caribbean, Mexico, and Central and South America until recent times.

 

The North American, Central American, and South American cigarette used various plant wrappers; when it was brought back to Spain, maize wrappers were introduced, and by the 17th century, fine paper. The resulting product was called papelate and is documented in Goya's paintings La Cometa, La Merienda en el Manzanares, and El juego de la pelota a pala (18th century).

 

By 1830, the cigarette had crossed into France, where it received the name cigarette; and in 1845, the French state tobacco monopoly began manufacturing them. The French word was adopted by English in the 1840s. Some American reformers promoted the spelling cigaret, but this was never widespread and is now largely abandoned.

 

The first patented cigarette-making machine was invented by Juan Nepomuceno Adorno of Mexico in 1847. However, production climbed markedly when another cigarette-making machine was developed in the 1880s by James Albert Bonsack, which vastly increased the productivity of cigarette companies, which went from making about 40,000 hand-rolled cigarettes daily to around 4 million.

 

In the English-speaking world, the use of tobacco in cigarette form became increasingly widespread during and after the Crimean War, when British soldiers began emulating their Ottoman Turkish comrades and Russian enemies, who had begun rolling and smoking tobacco in strips of old newspaper for lack of proper cigar-rolling leaf. This was helped by the development of tobaccos suitable for cigarette use, and by the development of the Egyptian cigarette export industry.

 

Cigarettes may have been initially used in a manner similar to pipes, cigars, and cigarillos and not inhaled; for evidence, see the Lucky Strike ad campaign asking consumers "Do You Inhale?" from the 1930s. As cigarette tobacco became milder and more acidic, inhaling may have become perceived as more agreeable. However, Moltke noticed in the 1830s (cf. Unter dem Halbmond) that Ottomans (and he himself) inhaled the Turkish tobacco and Latakia from their pipes (which are both initially sun-cured, acidic leaf varieties).

 

The widespread smoking of cigarettes in the Western world is largely a 20th-century phenomenon. At the start of the 20th century, the per capita annual consumption in the U.S. was 54 cigarettes (with less than 0.5% of the population smoking more than 100 cigarettes per year), and consumption there peaked at 4,259 per capita in 1965. At that time, about 50% of men and 33% of women smoked (defined as smoking more than 100 cigarettes per year). By 2000, consumption had fallen to 2,092 per capita, corresponding to about 30% of men and 22% of women smoking more than 100 cigarettes per year, and by 2006 per capita consumption had declined to 1,691; implying that about 21% of the population smoked 100 cigarettes or more per year.

 

The adverse health effects of cigarettes were known by the mid-19th century when they became known as coffins nails.[31] German doctors were the first to identify the link between smoking and lung cancer, which led to the first antitobacco movement in Nazi Germany. During World War I and World War II, cigarettes were rationed to soldiers. During the Vietnam War, cigarettes were included with C-ration meals. In 1975, the U.S. government stopped putting cigarettes in military rations. During the second half of the 20th century, the adverse health effects of tobacco smoking started to become widely known and text-only health warnings became common on cigarette packets.

 

The United States has not implemented graphical cigarette warning labels, which are considered a more effective method to communicate to the public the dangers of cigarette smoking. Canada, Mexico, Belgium, Denmark, Sweden, Thailand, Malaysia, India, Pakistan, Australia, Argentina, Brazil, Chile, Peru, Greece, the Netherlands, New Zealand, Norway, Hungary, the United Kingdom, France, Romania, Singapore, Egypt, Nepal and Turkey, however, have both textual warnings and graphic visual images displaying, among other things, the damaging effects tobacco use has on the human body.

 

The cigarette has evolved much since its conception; for example, the thin bands that travel transverse to the "axis of smoking" (thus forming circles along the length of the cigarette) are alternate sections of thin and thick paper to facilitate effective burning when being drawn, and retard burning when at rest. Synthetic particulate filters may remove some of the tar before it reaches the smoker.

 

The "holy grail" for cigarette companies has been a cancer-free cigarette. On record, the closest historical attempt was produced by scientist James Mold. Under the name project TAME, he produced the XA cigarette. However, in 1978, his project was terminated.

 

Since 1950, the average nicotine and tar content of cigarettes has steadily fallen. Research has shown that the fall in overall nicotine content has led to smokers inhaling larger volumes per puff.

 

LEGISLATION

SMOKING RESTRICTIONS

Many governments impose restrictions on smoking tobacco, especially in public areas. The primary justification has been the negative health effects of second-hand smoke. Laws vary by country and locality. Nearly all countries have laws restricting places where people can smoke in public, and over 40 countries have comprehensive smoke-free laws that prohibit smoking in virtually all public venues. Bhutan is currently the only country in the world to completely outlaw the cultivation, harvesting, production, and sale of tobacco and tobacco products under the Tobacco Control Act of Bhutan 2010. However, small allowances for personal possession are permitted as long as the possessors can prove that they have paid import duties. The Pitcairn Islands had previously banned the sale of cigarettes, but it now permits sales from a government-run store. The Pacific island of Niue hopes to become the next country to prohibit the sale of tobacco. Iceland is also proposing banning tobacco sales from shops, making it prescription-only and therefore dispensable only in pharmacies on doctor's orders. New Zealand hopes to achieve being tobacco-free by 2025 and Finland by 2040. Singapore and the Australian state of Tasmania have proposed a 'tobacco free millennium generation initiative' by banning the sale of all tobacco products to anyone born in and after the year 2000. In March 2012, Brazil became the world's first country to ban all flavored tobacco including menthols. It also banned the majority of the estimated 600 additives used, permitting only eight. This regulation applies to domestic and imported cigarettes. Tobacco manufacturers had 18 months to remove the noncompliant cigarettes, 24 months to remove the other forms of noncompliant tobacco. Under sharia law, the consumption of cigarettes by Muslims is prohibited.

 

SMOKING AGE

Beginning on April 1, 1998, the sale of cigarettes and other tobacco products to people under the state purchase age has been prohibited by law in all 50 states of the United States. The purchasing age in the United States is 18 in 42 of the 50 states — but 19 in Alabama, Alaska, Utah, and Nassau, Suffolk, and Onondaga Counties in New York, and 21 in California, Hawaii, New Jersey, Oregon, Maine and more than 180 municipalities across the nation. The intended effect of this is to prevent older high school students from purchasing cigarettes for their younger peers. In Massachusetts, parents and guardians are allowed to give cigarettes to minors, but sales to minors are prohibited.

 

Similar laws exist in many other countries. In Canada, most of the provinces require smokers to be 19 years of age to purchase cigarettes (except for Quebec and the prairie provinces, where the age is 18). However, the minimum age only concerns the purchase of tobacco, not use. Alberta, however, does have a law which prohibits the possession or use of tobacco products by all persons under 18, punishable by a $100 fine. Australia, New Zealand, Poland, and Pakistan have a nationwide ban on the selling of all tobacco products to people under the age of 18.

 

Since 1 October 2007, it has been illegal for retailers to sell tobacco in all forms to people under the age of 18 in three of the UK's four constituent countries (England, Wales, Northern Ireland, and Scotland) (rising from 16). It is also illegal to sell lighters, rolling papers, and all other tobacco-associated items to people under 18. It is not illegal for people under 18 to buy or smoke tobacco, just as it was not previously for people under 16; it is only illegal for the said retailer to sell the item. The age increase from 16 to 18 came into force in Northern Ireland on 1 September 2008. In the Republic of Ireland, bans on the sale of the smaller 10-packs and confectionery that resembles tobacco products (candy cigarettes) came into force on May 31, 2007, in a bid to cut underaged smoking.

 

Most countries in the world have a legal vending age of 18. In Macedonia, Italy, Malta, Austria, Luxembourg, and Belgium, the age for legal vending is 16. Since January 1, 2007, all cigarette machines in public places in Germany must attempt to verify a customer's age by requiring the insertion of a debit card. Turkey, which has one of the highest percentage of smokers in its population, has a legal age of 18. Japan is one of the highest tobacco-consuming nations, and requires purchasers to be 20 years of age (suffrage in Japan is 20 years old). Since July 2008, Japan has enforced this age limit at cigarette vending machines through use of the taspo smart card. In other countries, such as Egypt, it is legal to use and purchase tobacco products regardless of age.Germany raised the purchase age from 16 to 18 on the 1 September 2007.

 

Some police departments in the United States occasionally send an underaged teenager into a store where cigarettes are sold, and have the teen attempt to purchase cigarettes, with their own or no ID. If the vendor then completes the sale, the store is issued a fine. Similar enforcement practices are regularly performed by Trading Standards officers in the UK, Israel, and the Republic of Ireland.

 

TAXATION

Cigarettes are taxed both to reduce use, especially among youth, and to raise revenue.Higher prices for cigarettes discourage smoking. Every 10% increase in the price of cigarettes reduces youth smoking by about 7% and overall cigarette consumption by about 4%. The World Health Organization (WHO) recommends that globally cigarettes be taxed at a rate of three-quarters of cigarettes sale price as a way of deterring cancer and other negative health outcomes.

 

Cigarette sales are a significant source of tax revenue in many localities. This fact has historically been an impediment for health groups seeking to discourage cigarette smoking, since governments seek to maximize tax revenues. Furthermore, some countries have made cigarettes a state monopoly, which has the same effect on the attitude of government officials outside the health field.

 

In the United States, states are a primary determinant of the total tax rate on cigarettes. Generally, states that rely on tobacco as a significant farm product tend to tax cigarettes at a low rate. Coupled with the federal cigarette tax of $1.01 per pack, total cigarette-specific taxes range from $1.18 per pack in Missouri to $8.00 per pack in Silver Bay, New York.As part of the Family Smoking Prevention and Tobacco Control Act, the federal government collects user fees to fund Food and Drug Administration (FDA) regulatory measures over tobacco.

 

FIRE-SAFE CIGARETTE

According to Simon Chapman, a professor of public health at the University of Sydney, the burning agents in cigarette paper are responsible for fires and reducing them would be a simple and effective means of dramatically reducing the ignition propensity of cigarettes. Since the 1980s, prominent cigarette manufacturers such as Philip Morris and R.J. Reynolds developed fire safe cigarettes, but did not market them.

 

The burn rate of cigarette paper is regulated through the application of different forms of microcrystalline cellulose to the paper. Cigarette paper has been specially engineered by creating bands of different porosity to create "fire-safe" cigarettes. These cigarettes have a reduced idle burning speed which allows them to self-extinguish. This fire-safe paper is manufactured by mechanically altering the setting of the paper slurry.

 

New York was the first U.S. state to mandate that all cigarettes manufactured or sold within the state comply with a fire-safe standard. Canada has passed a similar nationwide mandate based on the same standard. All U.S. states are gradually passing fire-safe mandates.

 

The European Union in 2011 banned cigarettes that do not meet a fire-safety standard. According to a study made by the European Union in 16 European countries, 11,000 fires were due to people carelessly handling cigarettes between 2005 and 2007. This caused 520 deaths with 1,600 people injured.

 

CIGARETTE ADVERTISING

Many countries have restrictions on cigarette advertising, promotion, sponsorship, and marketing. For example, in the Canadian provinces of British Columbia, Saskatchewan and Alberta, the retail store display of cigarettes is completely prohibited if persons under the legal age of consumption have access to the premises. In Ontario, Manitoba, Newfoundland and Labrador, and Quebec, Canada and the Australian Capital Territory the display of tobacco is prohibited for everyone, regardless of age, as of 2010. This retail display ban includes noncigarette products such as cigars and blunt wraps.

 

WARNING MESSAGES IN PACKAGES

As a result of tight advertising and marketing prohibitions, tobacco companies look at the pack differently: they view it as a strong component in displaying brand imagery and a creating significant in-store presence at the point of purchase. Market testing shows the influence of this dimension in shifting the consumer's choice when the same product displays in an alternative package. Studies also show how companies have manipulated a variety of elements in packs designs to communicate the impression of lower in tar or milder cigarettes, whereas the components were the same.

 

Some countries require cigarette packs to contain warnings about health hazards. The United States was the first, later followed by other countries including Canada, most of Europe, Australia, Pakistan, India, Hong Kong, and Singapore. In 1985, Iceland became the first country to enforce graphic warnings on cigarette packaging. At the end of December 2010, new regulations from Ottawa increased the size of tobacco warnings to cover three-quarters of the cigarette package in Canada. As of November 2010, 39 countries have adopted similar legislation.

 

In February 2011, the Canadian government passed regulations requiring cigarette packs to contain 12 new images to cover 75% of the outside panel and eight new health messages on the inside panel with full color.

 

As of April 2011, Australian regulations require all packs to use a bland olive green that researchers determined to be the least attractive color, with 75% coverage on the front of the pack and all of the back consisting of graphic health warnings. The only feature that differentiates one brand from another is the product name in a standard color, position, font size, and style. Similar policies have since been adopted in France and the United Kingdom. In response to these regulations, Philip Morris International, Japan Tobacco Inc., British American Tobacco Plc., and Imperial Tobacco attempted to sue the Australian government. On August 15, 2012, the High Court of Australia dismissed the suit and made Australia the first country to introduce brand-free plain cigarette packaging with health warnings covering 90 and 70% of back and front packaging, respectively. This took effect on December 1, 2012.

 

CONSTRUCTION

Modern commercially manufactured cigarettes are seemingly simple objects consisting mainly of a tobacco blend, paper, PVA glue to bond the outer layer of paper together, and often also a cellulose acetate–based filter. While the assembly of cigarettes is straightforward, much focus is given to the creation of each of the components, in particular the tobacco blend. A key ingredient that makes cigarettes more addictive is the inclusion of reconstituted tobacco, which has additives to make nicotine more volatile as the cigarette burns.

 

PAPER

The paper for holding the tobacco blend may vary in porosity to allow ventilation of the burning ember or contain materials that control the burning rate of the cigarette and stability of the produced ash. The papers used in tipping the cigarette (forming the mouthpiece) and surrounding the filter stabilize the mouthpiece from saliva and moderate the burning of the cigarette, as well as the delivery of smoke with the presence of one or two rows of small laser-drilled air holes.

 

TOBACCO BLEND

The process of blending gives the end product a consistent taste from batches of tobacco grown in different areas of a country that may change in flavor profile from year to year due to different environmental conditions.

 

Modern cigarettes produced after the 1950s, although composed mainly of shredded tobacco leaf, use a significant quantity of tobacco processing byproducts in the blend. Each cigarette's tobacco blend is made mainly from the leaves of flue-cured brightleaf, burley tobacco, and oriental tobacco. These leaves are selected, processed, and aged prior to blending and filling. The processing of brightleaf and burley tobaccos for tobacco leaf "strips" produces several byproducts such as leaf stems, tobacco dust, and tobacco leaf pieces ("small laminate"). To improve the economics of producing cigarettes, these byproducts are processed separately into forms where they can then be added back into the cigarette blend without an apparent or marked change in the cigarette's quality. The most common tobacco byproducts include:

 

Blended leaf (BL) sheet: a thin, dry sheet cast from a paste made with tobacco dust collected from tobacco stemming, finely milled burley-leaf stem, and pectin.

Reconstituted leaf (RL) sheet: a paper-like material made from recycled tobacco fines, tobacco stems and "class tobacco", which consists of tobacco particles less than 30 mesh in size (about 0.6 mm) that are collected at any stage of tobacco processing: RL is made by extracting the soluble chemicals in the tobacco byproducts, processing the leftover tobacco fibers from the extraction into a paper, and then reapplying the extracted materials in concentrated form onto the paper in a fashion similar to what is done in paper sizing. At this stage, ammonium additives are applied to make reconstituted tobacco an effective nicotine delivery system.

Expanded (ES) or improved stem (IS): ES is rolled, flattened, and shredded leaf stems that are expanded by being soaked in water and rapidly heated. Improved stem follows the same process, but is simply steamed after shredding. Both products are then dried. These products look similar in appearance, but are different in taste.

 

In recent years, the manufacturers' pursuit of maximum profits has led to the practice of using not just the leaves, but also recycled tobacco offal and the plant stem. The stem is first crushed and cut to resemble the leaf before being merged or blended into the cut leaf. According to data from the World Health Organization, the amount of tobacco per 1000 cigarettes fell from 2.28 pounds in 1960 to 0.91 pounds in 1999, largely as a result of reconstituting tobacco, fluffing, and additives.

 

A recipe-specified combination of brightleaf, burley-leaf, and oriental-leaf tobacco is mixed with various additives to improve its flavors.

 

ADDITIVES

Various additives are combined into the shredded tobacco product mixtures, with humectants such as propylene glycol or glycerol, as well as flavoring products and enhancers such as cocoa solids, licorice, tobacco extracts, and various sugars, which are known collectively as "casings". The leaf tobacco is then shredded, along with a specified amount of small laminate, expanded tobacco, BL, RL, ES, and IS. A perfume-like flavor/fragrance, called the "topping" or "toppings", which is most often formulated by flavor companies, is then blended into the tobacco mixture to improve the consistency in flavor and taste of the cigarettes associated with a certain brand name.[85] Additionally, they replace lost flavors due to the repeated wetting and drying used in processing the tobacco. Finally, the tobacco mixture is filled into cigarette tubes and packaged.

 

A list of 599 cigarette additives, created by five major American cigarette companies, was approved by the Department of Health and Human Services in April 1994. None of these additives is listed as an ingredient on the cigarette pack(s). Chemicals are added for organoleptic purposes and many boost the addictive properties of cigarettes, especially when burned.

 

One of the classes of chemicals on the list, ammonia salts, convert bound nicotine molecules in tobacco smoke into free nicotine molecules. This process, known as freebasing, could potentially increase the effect of nicotine on the smoker, but experimental data suggests that absorption is, in practice, unaffected.

 

CIGARETTE TUBE

Cigarette tubes are prerolled cigarette paper usually with an acetate or paper filter at the end. They have an appearance similar to a finished cigarette, but are without any tobacco or smoking material inside. The length varies from what is known as King Size (84 mm) to 100s (100 mm).

 

Filling a cigarette tube is usually done with a cigarette injector (also known as a shooter). Cone-shaped cigarette tubes, known as cones, can be filled using a packing stick or straw because of their shape. Cone smoking is popular because as the cigarette burns, it tends to get stronger and stronger. A cone allows more tobacco to be burned at the beginning than the end, allowing for an even flavor

 

The United States Tobacco Taxation Bureau defines a cigarette tube as "Cigarette paper made into a hollow cylinder for use in making cigarettes."

 

CIGARETTE FILTER

A cigarette filter or filter tip is a component of a cigarette. Filters are typically made from cellulose acetate fibre. Most factory-made cigarettes are equipped with a filter; those who roll their own can buy them separately. Filters can reduce some substances from smoke but do not make cigarettes any safer to smoke.

 

CIGARETTE BUTT

The common name for the remains of a cigarette after smoking is a cigarette butt. The butt is typically about 30% of the cigarette's original length. It consists of a tissue tube which holds a filter and some remains of tobacco mixed with ash. They are the most numerically frequent litter in the world. Cigarette butts accumulate outside buildings, on parking lots, and streets where they can be transported through storm drains to streams, rivers, and beaches. It is also called a fag-end or dog-end.

 

In a 2013 trial the city of Vancouver, British Columbia, partnered with TerraCycle to create a system for recycling of cigarette butts. A reward of 1¢ per collected butt was offered to determine the effectiveness of a deposit system similar to that of beverage containers

 

LIGHTS

Some cigarettes are marketed as “Lights”, “Milds”, or “Low-tar.” These cigarettes were historically marketed as being less harmful, but there is no research showing that they are any less harmful. The filter design is one of the main differences between light and regular cigarettes, although not all cigarettes contain perforated holes in the filter. In some light cigarettes, the filter is perforated with small holes that theoretically diffuse the tobacco smoke with clean air. In regular cigarettes, the filter does not include these perforations. In ultralight cigarettes, the filter's perforations are larger. he majority of major cigarette manufacturers offer a light, low-tar, and/or mild cigarette brand. Due to recent U.S. legislation prohibiting the use of these descriptors, tobacco manufacturers are turning to color-coding to allow consumers to differentiate between regular and light brands.

 

REPLACEMENT

An electronic cigarette is a handheld battery-powered vaporizer that simulates smoking by providing some of the behavioral aspects of smoking, including the hand-to-mouth action of smoking, but without combusting tobacco. Using an e-cigarette is known as "vaping" and the user is referred to as a "vaper." Instead of cigarette smoke, the user inhales an aerosol, commonly called vapor. E-cigarettes typically have a heating element that atomizes a liquid solution called e-liquid. E-cigarettes are automatically activated by taking a puff; others turn on manually by pressing a button. Some e-cigarettes look like traditional cigarettes, but they come in many variations. Most versions are reusable, though some are disposable. There are first-generation, second-generation, third-generation, and fourth-generation devices. E-liquids usually contain propylene glycol, glycerin, nicotine, flavorings, additives, and differing amounts of contaminants. E-liquids are also sold without propylene glycol, nicotine, or flavors.

 

The benefits and the health risks of e-cigarettes are uncertain. There is tentative evidence they may help people quit smoking, although they have not been proven to be more effective than smoking cessation medicine. There is concern with the possibility that non-smokers and children may start nicotine use with e-cigarettes at a rate higher than anticipated than if they were never created. Following the possibility of nicotine addiction from e-cigarette use, there is concern children may start smoking cigarettes. Youth who use e-cigarettes are more likely to go on to smoke cigarettes. Their part in tobacco harm reduction is unclear, while another review found they appear to have the potential to lower tobacco-related death and disease. Regulated US Food and Drug Administration nicotine replacement products may be safer than e-cigarettes, but e-cigarettes are generally seen as safer than combusted tobacco products. It is estimated their safety risk to users is similar to that of smokeless tobacco. The long-term effects of e-cigarette use are unknown. The risk from serious adverse events was reported in 2016 to be low. Less serious adverse effects include abdominal pain, headache, blurry vision, throat and mouth irritation, vomiting, nausea, and coughing. Nicotine itself is associated with some health harms. In 2019, an outbreak of severe lung illness across multiple states in the US has been linked to the use of vaping products.

 

E-cigarettes create vapor made of fine and ultrafine particles of particulate matter, which have been found to contain propylene glycol, glycerin, nicotine, flavors, tiny amounts of toxicants, carcinogens, heavy metals, and metal nanoparticles, and other substances. Its exact composition varies across and within manufacturers, and depends on the contents of the liquid, the physical and electrical design of the device, and user behavior, among other factors. E-cigarette vapor potentially contains harmful chemicals not found in tobacco smoke. E-cigarette vapor contains fewer toxic chemicals, and lower concentrations of potential toxic chemicals than cigarette smoke. The vapor is probably much less harmful to users and bystanders than cigarette smoke,although concern exists that the exhaled vapor may be inhaled by non-users, particularly indoors.
