Tobacco smoking is the practice of burning

European colonists, where it followed common trade routes. The practice encountered criticism from its first import into the Western world onwards but embedded itself in certain strata of a number of societies before becoming widespread upon the introduction of automated cigarette-rolling apparatus.[2][3]

Smoking is the most common method of consuming tobacco, and tobacco is the most common substance smoked. The agricultural product is often mixed with additives

endorphins are released, which are often associated with pleasure,[8] leading to addiction.[9]

German scientists identified a link between smoking and

developed world have either peaked or declined.[12] However, they continue to climb in the developing world.[13] As of 2008 to 2010, tobacco is used by about 49% of men and 11% of women aged 15 or older in fourteen low-income and middle-income countries (Bangladesh, Brazil, China, Egypt, India, Mexico, Philippines, Russia, Thailand, Turkey, Ukraine, Uruguay and Vietnam), with about 80% of this usage in the form of smoking.[14] The gender gap tends to be less pronounced in lower age groups.[15][16] According to the World Health Organization, 8 million annual deaths are caused by tobacco smoking.[17]

Many smokers begin during adolescence or early adulthood.

History

Use in ancient cultures

Smoking's history dates back to as early as 5000–3000 BC, when the agricultural product began to be cultivated in Mesoamerica and South America; consumption later evolved into burning the plant substance either by accident or with intent of exploring other means of consumption.

Babylonians, the Indians, and the Chinese – burnt incense during religious rituals. Smoking in the Americas probably had its origins in the incense-burning ceremonies of shamans but was later adopted for pleasure or as a social tool.[21] The smoking of tobacco and various hallucinogenic drugs was used to achieve trances and to come into contact with the spirit world.[22] Also, to stimulate respiration, tobacco smoke enemas were used.[23]

Eastern North American tribes would carry large amounts of tobacco in pouches as a readily accepted trade item and would often smoke it in ceremonial pipes, either in sacred ceremonies or to seal bargains.[24] Adults as well as children enjoyed the practice.[25] It was believed that tobacco was a gift from the Creator and that the exhaled tobacco smoke was capable of carrying one's thoughts and prayers to heaven.[26]

Apart from smoking, tobacco had uses as medicine. As a pain killer it was used for earache and toothache and occasionally as a

cough root, Leptotaenia multifida, the addition of which was thought to be particularly good for asthma and tuberculosis.[27]

Popularization

In 1612, six years after the settlement of

Virginia joint stock company from its failed gold expeditions.[28] In order to meet demands from the Old World, tobacco was grown in succession, quickly depleting the soil. This became a motivator to settle west into the unknown continent, and likewise an expansion of tobacco production.[29]

Frenchman Jean Nicot (from whose name the word nicotine is derived) introduced tobacco to France in 1560, and tobacco then spread to England. The first report of a smoking Englishman is of a sailor in Bristol in 1556, seen "emitting smoke from his nostrils".[2] Like tea, coffee and opium, tobacco was just one of many intoxicants that was originally used as a form of medicine.[30] Tobacco was introduced around 1600 by French merchants in what today is modern-day Gambia and Senegal. At the same time, caravans from Morocco brought tobacco to the areas around Timbuktu, and the Portuguese brought the commodity (and the plant) to southern Africa, establishing the popularity of tobacco throughout all of Africa by the 1650s.

Soon after its introduction to the Old World, tobacco came under frequent criticism from state and religious leaders.

shogunate as being a threat to the military economy by letting valuable farmland go to waste for the use of a recreational drug instead of being used to plant food crops.[31]

Religious leaders have often been prominent among those who considered smoking immoral or outright blasphemous. In 1634, the

James I of England, a staunch smoking opponent and the author of A Counterblaste to Tobacco, tried to curb the new trend by enforcing a 4000% tax increase on tobacco in 1604 it was unsuccessful, as suggested by the presence of around 7,000 tobacco outlets in London by the early 17th century. From this point on for some centuries, several administrations withdrew from efforts at discouragement and instead turned tobacco trade and cultivation into sometimes lucrative government monopolies.[32][33]

By the mid-17th century most major civilizations had been introduced to tobacco smoking and in many cases had already assimilated it into the native culture, despite some continued attempts upon the parts of rulers to eliminate the practice with penalties or fines. Tobacco, both product and plant, followed the major trade routes to major ports and markets, and then on into the hinterlands. The English language term smoking appears to have entered currency in the late 18th century, before which less abbreviated descriptions of the practice such as drinking smoke were also in use.[2]

Growth in the US remained stable until the American Civil War in 1860s, when the primary agricultural workforce shifted from

James Bonsack created a machine in 1881 to partially automate their manufacture.[34]

Social attitudes and public health

In 1912 and 1932 in Germany, anti-smoking groups, often associated with anti-liquor groups,[35] first published advocacy against the consumption of tobacco in the journal Der Tabakgegner (The Tobacco Opponent). In 1929, Fritz Lickint of Dresden, Germany, published a paper containing formal statistical evidence of a lung cancer–tobacco link. During the Great Depression Adolf Hitler condemned his earlier smoking habit as a waste of money,[36] and later with stronger assertions. This movement was further strengthened with Nazi reproductive policy as women who smoked were viewed as unsuitable to be wives and mothers in a German family.[37] In the 20th century, smoking was common. There were social events like the smoke night which promoted the habit.

The

post-war Germany steadily rose from 460 in 1950 to 1,523 in 1963.[10] By the end of the 20th century, anti-smoking campaigns in Germany were unable to exceed the effectiveness of the Nazi-era climax in the years 1939–41 and German tobacco health research was described by Robert N. Proctor as "muted".[10]

In 1950,

British Medical Journal showing a close link between smoking and lung cancer.[40] Beginning in December 1952, the magazine Reader's Digest published "Cancer by the Carton", a series of articles that linked smoking with lung cancer.[41]

In 1954, the British Doctors Study, a prospective study of some 40 thousand doctors for about 2.5 years, confirmed the suggestion, based on which the government issued advice that smoking and lung cancer rates were related.[11] In January 1964, the United States Surgeon General's Report on Smoking and Health likewise began suggesting the relationship between smoking and cancer.[42]

As scientific evidence mounted in the 1980s, tobacco companies claimed contributory negligence as the adverse health effects were previously unknown or lacked substantial credibility. Health authorities sided with these claims up until 1998, from which they reversed their position. The Tobacco Master Settlement Agreement, originally between the four largest US tobacco companies and the attorneys general of 46 states, restricted certain types of tobacco advertisement and required payments for health compensation; which later amounted to the largest civil settlement in United States history.[43]

Social campaigns have been instituted in many places to discourage smoking, such as Canada's National Non-Smoking Week.

From 1965 to 2006, rates of smoking in the United States declined from 42% to 20.8%.

developing world, however, tobacco consumption continued to rise at 3.4% in 2002.[13] In Africa, smoking is in most areas considered to be modern, and many of the strong adverse opinions that prevail in the West receive much less attention.[45] Today Russia leads as the top consumer of tobacco followed by Indonesia, Laos, Ukraine, Belarus, Greece, Jordan, and China.[46]

Consumption

Methods

oxidation and degradation of carotenoids in tobacco leaf. This produces certain compounds in the tobacco leaves which can be attributed to sweet hay, tea, rose oil, or fruity aromatic flavors. Before packaging, the tobacco is often combined with other additives in order to increase the addictive potency, shift the product's pH, or improve the effects of smoke by making it more palatable. In the United States these additives are regulated to 599 substances.[4]
The product is then processed, packaged, and shipped to consumer markets.

Common methods of consuming tobacco include the following:

Beedi
Beedis are thin South Asian cigarettes filled with tobacco flakes and wrapped in a tendu leaf tied with a string at one end. They produce higher levels of carbon monoxide, nicotine, and tar than cigarettes typical in the United States.[47][48]
Tendu Patta (Leaf) collection for Beedi industries
Cigars
Cigars are tightly rolled bundles of dried and fermented tobacco which are ignited so that smoke may be drawn into the smoker's mouth. They are generally not inhaled because of the high alkalinity of the smoke, which can quickly become irritating to the trachea and lungs. The prevalence of cigar smoking varies depending on location, historical period, and population surveyed, and prevalence estimates vary somewhat depending on the survey method. The United States is the top consuming country by far, followed by Germany and the United Kingdom; the US and Western Europe account for about 75% of cigar sales worldwide.[49] As of 2005 it is estimated that 4.3% of men and 0.3% of women smoke cigars in the US.[50]
Cigarettes
Cigarettes, French for "small cigar", are a product consumed through smoking and manufactured out of cured and finely cut tobacco leaves and reconstituted tobacco, often combined with other additives, which are then rolled or stuffed into a paper-wrapped cylinder.[4] Cigarettes are ignited and inhaled, usually through a cellulose acetate filter, into the mouth and lungs.

Hookah
Hookah are a single or multi-stemmed (often glass-based) water pipe for smoking. Originally from India, the hookah was a symbol of pride and honor for the landlords, kings and other such high class people. Now, the hookah has gained immense popularity, especially in the Middle East. A hookah operates by water filtration and indirect heat. It can be used for smoking herbal fruits, tobacco, or cannabis.
Kretek
Kretek are cigarettes made with a complex blend of tobacco, cloves and a flavoring "sauce". It was first introduced in the 1880s in Kudus, Java, to deliver the medicinal eugenol of cloves to the lungs. The quality and variety of tobacco play an important role in kretek production, from which kretek can contain more than 30 types of tobacco. Minced dried clove buds weighing about one-third of the tobacco blend are added to add flavoring. In 2004 the United States prohibited cigarettes from having a "characterizing flavor" of certain ingredients other than tobacco and menthol, thereby removing kretek from being classified as cigarettes.[51]
Pipe smoking
Pipe smoking is done with a tobacco pipe, typically consisting of a small chamber (the bowl) for the combustion of the tobacco to be smoked and a thin stem (shank) that ends in a mouthpiece (the bit). Shredded pieces of tobacco are placed into the chamber and ignited.
Roll-your-own
Roll-your-own or hand-rolled cigarettes, often called "rollies", "cigi" or "Roll-ups", are very popular particularly in European countries and the UK. These are prepared from loose tobacco, cigarette papers, and filters all bought separately. They are usually much cheaper than ready-made cigarettes and small contraptions can be bought making the process easier.
Vaporizer
A
vaporizer is a device used to sublimate the active ingredients of plant material. Rather than burning the herb, which produces potentially irritating, toxic, or carcinogenic
by-products; a vaporizer heats the material in a partial vacuum so that the active compounds contained in the plant boil off into a vapor. This method is often preferable when medically administering the smoke substance, as opposed to directly pyrolyzing the plant material.

Physiology

The active substances in tobacco, especially cigarettes, are administered by burning the leaves and inhaling the vaporized gas that results. This quickly and effectively delivers substances into the bloodstream by

substrates among these drugs.[54]

The absorbed

When tobacco is smoked, most of the nicotine is pyrolyzed. However, a dose sufficient to cause mild somatic dependency and mild to strong psychological dependency remains. There is also a formation of

MAO inhibitor) from the acetaldehyde in tobacco smoke. This may play a role in nicotine addiction, by facilitating a dopamine release in the nucleus accumbens as a response to nicotine stimuli.[58] Using rat studies, withdrawal after repeated exposure to nicotine results in less responsive nucleus accumbens cells, which produce dopamine responsible for reinforcement.[59]

Demographics

Percentage of females smoking any tobacco product. Note that there is a difference between the scales used for males and the scales used for females.[46]

As of 2000, smoking was practiced by around 1.22 billion people. At current rates of 'smoker replacement' and market growth, this may reach around 1.9 billion in 2025.[60]

Smoking may be up to five times more prevalent among men than women in some communities,[60] although the gender gap usually declines with younger age.[15][16] In some developed countries smoking rates for men have peaked and begun to decline, while for women they continue to climb.[61]

As of 2002, about twenty percent of young teenagers (13–15) smoked worldwide. 80,000 to 100,000 children begin smoking every day, roughly half of whom live in Asia. Half of those who begin smoking in

adolescent years are projected to go on to smoke for 15 to 20 years.[13] As of 2019 in the United States, roughly 800,000 high school students smoke.[62]

The

developing world, however, tobacco consumption is rising by 3.4% per year as of 2002.[13]

The WHO in 2004 projected 58.8 million deaths to occur globally,[64] from which 5.4 million are tobacco-attributed,[65] and 4.9 million as of 2007.[66] As of 2002, 70% of the deaths are in developing countries.[66] As of 2017, smoking causes one in ten deaths worldwide, with half of those deaths in the US, China, India and Russia.[67]

Psychology

Takeup

Sigmund Freud, whose doctor assisted his suicide because of oral cancer caused by smoking[68]

Most smokers begin smoking during adolescence or early adulthood. Some studies also show that smoking can also be linked to various mental health complications.[69] Smoking has elements of risk-taking and rebellion, which often appeal to young people. [citation needed] The presence of peers that smoke and media featuring high-status models smoking may also encourage smoking. Because teenagers are influenced more by their peers than by adults [dubious ], attempts by parents, schools, and health professionals at preventing people from trying cigarettes are often unsuccessful.[70][71]

Children of smoking parents are more likely to smoke than children with non-smoking parents. Children of parents who smoke are less likely to quit smoking.[18] One study found that parental smoking cessation was associated with less adolescent smoking, except when the other parent currently smoked.[72] A current study tested the relation of adolescent smoking to rules regulating where adults are allowed to smoke in the home. Results showed that restrictive home smoking policies were associated with lower likelihood of trying smoking for both middle and high school students.[73]

Behavioural research generally indicates that teenagers begin their smoking habits due to peer pressure, and cultural influence portrayed by friends. However, one study found that direct pressure to smoke cigarettes played a less significant part in adolescent smoking, with

is a greater cause of adolescent smoking.

Psychologist Hans Eysenck (who later was questioned for nonplausible results

Extraversion is the trait that is most associated with smoking, and smokers tend to be sociable, impulsive, risk taking, and excitement seeking individuals.[81]

Persistence

The reasons given by some smokers for this activity have been categorized as addictive smoking, pleasure from smoking, tension reduction/relaxation, social smoking, stimulation, habit/automatism, and handling. There are gender differences in how much each of these reasons contribute, with females more likely than males to cite tension reduction/relaxation, stimulation and social smoking.[82]

Some smokers argue that the depressant effect of smoking allows them to calm their nerves, often allowing for increased concentration. However, according to the Imperial College London, "Nicotine seems to provide both a stimulant and a depressant effect, and it is likely that the effect it has at any time is determined by the mood of the user, the environment and the circumstances of use. Studies have suggested that low doses have a depressant effect, while higher doses have stimulant effect."[83]

Patterns

A number of studies have established that cigarette sales and smoking follow distinct time-related patterns. For example, cigarette sales in the United States of America have been shown to follow a strongly seasonal pattern, with the high months being the months of summer, and the low months being the winter months.[84]

Similarly, smoking has been shown to follow distinct circadian patterns during the waking day—with the high point usually occurring shortly after waking in the morning, and shortly before going to sleep at night.[85]

Effects

Health

Tobacco smoking is the

leading cause of preventable death and a global public health concern.[86] There are 1.3 billion tobacco users in the world, as per latest data from WHO.[17] One person dies every six seconds from a tobacco related disease.[87]

Common adverse effects of tobacco smoking. The more common effects are in bold face.[88]

Tobacco use leads most commonly to diseases affecting the heart and lungs, with smoking being a major risk factor for

malignant diseases.[89][94][100][101]

Tobacco smoke is a complex mixture of over 7,000

alcohols, and heavy metals, all of which are dangerous to human health.[98][111][112][113][114] A comparison of 13 common hookah flavors found that melon flavors are the most dangerous, with their smoke containing four classes of hazards in high concentrations.[114]

The World Health Organization estimates that tobacco caused 8 million deaths in 2004[17] and 100 million deaths over the course of the 20th century.[115] Similarly, the United States Centers for Disease Control and Prevention describes tobacco use as "the single most important preventable risk to human health in developed countries and an important cause of premature death worldwide."[116] Although 70% of smokers state their intention to quit only 3–5% are actually successful in doing so.[117]

The probabilities of death from lung cancer before age 75 in the United Kingdom are 0.2% for men who never smoked (0.4% for women), 5.5% for male former smokers (2.6% in women), 15.9% for current male smokers (9.5% for women) and 24.4% for male "heavy smokers" defined as smoking more than 25 cigarettes per day (18.5% for women).[118] Tobacco smoke can combine with other carcinogens present within the environment in order to produce elevated degrees of lung cancer.

The risk of lung cancer decreases almost from the first day someone quits smoking and it drops by 50% after 10 years of smoking cessation.[17] Healthy cells that have escaped mutations grow and replace the damaged ones in the lungs. In the research dated December 2019, 40% of cells in former smokers looked like those of people who had never smoked.[119]

Rates of smoking have generally leveled-off or declined in the developed world. Smoking rates in the United States have dropped by half from 1965 to 2006, falling from 42% to 20.8% in adults.[120] In the developing world, tobacco consumption is rising by 3.4% per year.[121]

Smoking alters the transcriptome of the lung parenchyma; the expression levels of a panel of seven genes (KMO, CD1A, SPINK5, TREM2, CYBB, DNASE2B, FGG) are increased in the lung tissue of smokers.[122]

Passive smoking is the inhalation of tobacco smoke by individuals who are not actively smoking. This smoke is known as second-hand smoke (SHS) or environmental tobacco smoke (ETS) when the burning end is present, and third-hand smoke after the burning end has been extinguished. Because of its negative implications, exposure to SHS has played a central role in the regulation of tobacco products. Six hundred thousand deaths were attributed to SHS in 2004. It also has been known to produce skin conditions such as freckles and dryness.[123]

In 2015, a meta-analysis found that smokers were at greater risk of developing

psychotic disorder.[124] Tobacco has also been described an anaphrodisiac due to its propensity for causing erectile dysfunction.[125] There is a correlation between tobacco smoking and a reduced risk of Parkinson's disease.[126][127]

Economic

In countries where there is a

universally funded healthcare system, the government covers the cost of medical care for smokers who become ill through smoking in the form of increased taxes. Two broad debating positions exist on this front, the "pro-smoking" argument suggesting that heavy smokers generally do not live long enough to develop the costly and chronic illnesses which affect the elderly, reducing society's healthcare burden, and the "anti-smoking" argument suggests that the healthcare burden is increased because smokers get chronic illnesses younger and at a higher rate than the general population. Data on both positions has been contested. The Centers for Disease Control and Prevention published research in 2002 claiming that the cost of each pack of cigarettes sold in the United States was more than $7 in medical care and lost productivity.[128] The cost may be higher, with another study putting it as high as $41 per pack, most of which however is on the individual and his/her family.[129] This is how one author of that study puts it when he explains the very low cost for others: "The reason the number is low is that for private pensions, Social Security, and Medicare — the biggest factors in calculating costs to society — smoking actually saves money. Smokers die at a younger age and don't draw on the funds they've paid into those systems."[129] Other research demonstrates that premature death caused by smoking may redistribute Social Security income in unexpected ways that affect behavior and reduce the economic well-being of smokers and their dependents.[130] To further support this, whatever the rate of smoking consumption is per day, smokers have a greater lifetime medical cost on average compared to a non-smoker by an estimated $6000.[117] Between the cost for lost productivity and health care expenditures combined, cigarette smoking costs at least 193 billion dollars (Research also shows that smokers earn less money than nonsmokers[131]). As for secondhand smoke, the cost is over 10 billion dollars.[132]

By contrast, some non-scientific studies, including one conducted by Philip Morris in the Czech Republic called Public Finance Balance of Smoking in the Czech Republic[133] and another by the Cato Institute,[134] support the opposite position. Philip Morris has explicitly apologised for the former study, saying: "The funding and public release of this study which, among other things, detailed purported cost savings to the Czech Republic due to premature deaths of smokers, exhibited terrible judgment as well as a complete and unacceptable disregard of basic human values. For one of our tobacco companies to commission this study was not just a terrible mistake, it was wrong. All of us at Philip Morris, no matter where we work, are extremely sorry for this. No one benefits from the very real, serious and significant diseases caused by smoking."[133]

Between 1970 and 1995, per-capita cigarette consumption in poorer developing countries increased by 67 percent, while it dropped by 10 percent in the richer developed world. Eighty percent of smokers now live in less developed countries. By 2030, the World Health Organization (WHO) forecasts that 10 million people a year will die of smoking-related illness, making it the single biggest cause of death worldwide, with the largest increase to be among women. WHO forecasts the 21st century's death rate from smoking to be ten times the 20th century's rate ("Washingtonian" magazine, December 2007).

The tobacco industry is known to be one of the largest global enterprises in the world. The six biggest tobacco companies made a combined profit of $35.1 billion (Jha et al., 2014) in 2010.[135]

Social

Skull with a burning cigarette, by Vincent van Gogh

Famous smokers of the past used cigarettes or pipes as part of their image, such as

Sir Arthur Conan Doyle, smoked a pipe, cigarettes, and cigars. The DC Vertigo comic book character John Constantine, created by Alan Moore, is synonymous with smoking, so much so that the first storyline by Preacher creator Garth Ennis centered around John Constantine contracting lung cancer. Professional wrestler James Fullington
, while in character as "The Sandman", is a chronic smoker in order to appear "tough".

The problem of smoking at home is particularly difficult for women in many cultures (especially Arab cultures), where it may not be acceptable for a woman to ask her husband not to smoke at home or in the presence of her children. Studies have shown that pollution levels for smoking areas indoors are higher than levels found on busy roadways, in closed motor garages, and during fire storms.[clarification needed] Furthermore, smoke can spread from one room to another, even if doors to the smoking area are closed.[136]

The ceremonial smoking of tobacco, and praying with a

fasting however, it is forbidden to smoke tobacco.[138] In the Baháʼí Faith, smoking tobacco is discouraged though not forbidden.[139]

Public policy

On 27 February 2005 the WHO Framework Convention on Tobacco Control, took effect. The FCTC is the world's first public health treaty. Countries that sign on as parties agree to a set of common goals, minimum standards for tobacco control policy, and to cooperate in dealing with cross-border challenges such as cigarette smuggling. Currently the WHO declares that 4 billion people will be covered by the treaty, which includes 168 signatories.[140] Among other steps, signatories are to put together legislation that will eliminate secondhand smoke in indoor workplaces, public transport, indoor public places and, as appropriate, other public places.

Taxation

Many governments have introduced

excise taxes on cigarettes in order to reduce the consumption of cigarettes. The World Health Organisation finds that:[141]

The structure of tobacco excise taxes varies considerably across countries, with lower income countries more likely to rely more on ad valorem excises and higher income countries more likely to rely more on specific excise taxes, while many countries at all income levels use a mix of specific and ad valorem excises.

Tobacco excise tax systems are quite complex in several countries, where different tax rates are applied based on prices, product characteristics such as presence/absence of a filter or length, packaging, weight, tobacco content, and/or production or sales volume. These complex systems are difficult to administer, create opportunities for tax avoidance, and are less effective from a public health perspective.

Globally, cigarette excise taxes account for less than 45 percent of cigarette prices, on average, while all taxes applied to cigarettes account for just over half of half of price. Higher income countries levy higher taxes on tobacco products and these taxes account for a greater share of price, with both the absolute tax and share of price accounted for by tax falling as country incomes fall.

In 2002, the Centers for Disease Control and Prevention said that each pack of cigarettes[quantify] sold in the United States costs the nation more than $7 in medical care and lost productivity,[128] around $3400 per year per smoker. Another study by a team of health economists finds the combined price paid by their families and society is about $41 per pack of cigarettes.[142]

Substantial scientific evidence shows that higher cigarette prices result in lower overall cigarette consumption. Most studies indicate that a 10% increase in price will reduce overall cigarette consumption by 3% to 5%. Youth, minorities, and low-income smokers are two to three times more likely to quit or smoke less than other smokers in response to price increases.

, however, i.e. a large rise in price will only result in a small decrease in consumption.

Many nations have implemented some form of tobacco taxation. As of 1997, Denmark had the highest cigarette tax burden of $4.02 per pack. Taiwan only had a tax burden of $0.62 per pack. The federal government of the United States charges $1.01 per pack.[145]

Cigarette taxes vary widely from state to state in the United States. For example, Missouri has a cigarette tax of only 17 cents per pack, the nation's lowest, while New York has the highest cigarette tax in the U.S.: $4.35 per pack. In Alabama, Illinois, Missouri, New York City, Tennessee, and Virginia, counties and cities may impose an additional limited tax on the price of cigarettes.[146] Sales taxes are also levied on tobacco products in most jurisdictions.

In the United Kingdom, as of April 2023, a packet of 20 cigarettes has a tax added of 16.5% of the retail price plus £5.89.[147] The UK has a significant black market for tobacco, and it has been estimated by the tobacco industry that 27% of cigarette and 68% of handrolling tobacco consumption is non-UK duty paid (NUKDP).[148]

In Australia total taxes account for 62.5% of the final price of a packet of cigarettes (2011 figures). These taxes include federal excise or customs duty and

Goods and Services Tax.[149]

Restrictions

In June 1967, the US Federal Communications Commission ruled that programmes broadcast on a television station which discussed smoking and health were insufficient to offset the effects of paid advertisements that were broadcast for five to ten minutes each day. In April 1970, the US Congress passed the Public Health Cigarette Smoking Act banning the advertising of cigarettes on television and radio starting on 2 January 1971.[150]

The Tobacco Advertising Prohibition Act 1992 expressly prohibited almost all forms of Tobacco advertising in Australia, including the sponsorship of sporting or other cultural events by cigarette brands.

All tobacco advertising and sponsorship on television has been banned within the European Union since 1991 under the Television Without Frontiers Directive (1989).[151] This ban was extended by the Tobacco Advertising Directive, which took effect in July 2005 to cover other forms of media such as the internet, print media, and radio. The directive does not include advertising in cinemas and on billboards or using merchandising – or tobacco sponsorship of cultural and sporting events which are purely local, with participants coming from only one Member State[152] as these fall outside the jurisdiction of the European Commission. However, most member states have transposed the directive with national laws that are wider in scope than the directive and cover local advertising. A 2008 European Commission report concluded that the directive had been successfully transposed into national law in all EU member states, and that these laws were well implemented.[153]

Some countries also impose legal requirements on the packaging of tobacco products. For example, in the countries of the European Union, Turkey, Australia[154] and South Africa, cigarette packs must be prominently labeled with the health risks associated with smoking.[155] Canada, Australia, Thailand, Iceland and Brazil have also imposed labels upon cigarette packs warning smokers of the effects, and they include graphic images of the potential health effects of smoking. Cards are also inserted into cigarette packs in Canada. There are sixteen of them, and only one comes in a pack. They explain different methods of quitting smoking. Also, in the United Kingdom, there have been a number of graphic NHS advertisements, one showing a cigarette filled with fatty deposits, as if the cigarette is symbolizing the artery of a smoker.

Some countries have also banned advertisement at point of sale. United Kingdom and Ireland have limited the advertisement of tobacco at retailers.[156][157] This includes storing of cigarettes behind a covered shelf not visible to the public. They do however allow some limited advertising at retailers. Norway has a complete ban of point of sale advertising.[158] This includes smoking products and accessories. Implementing these policies can be challenging, all of these countries experienced resistance and challenges from the tobacco industry.[159][160][161] The World Health Organisation recommends the complete ban of all types of advertisement or product placement, including at vending machines, at airports and on internet shops selling tobacco.[162] The evidence is as yet unclear as to the effect of such bans.  

Many countries have a

smoking age. In many countries, including the United States, most European Union member states, New Zealand, Canada, South Africa, Israel, India,[18] Brazil, Chile, Costa Rica and Australia, it is illegal to sell tobacco products to minors and in the Netherlands, Austria, Belgium, Denmark and South Africa it is illegal to sell tobacco products to people under the age of 18. On 1 September 2007 the minimum age to buy tobacco products in Germany rose from 16 to 18, as well as in the United Kingdom where on 1 October 2007 it rose from 16 to 18.[163]
Underlying such laws is the belief that people should make an informed decision regarding the risks of tobacco use. These laws have a lax enforcement in some nations and states. In China, Turkey, and many other countries usually a child will have little problem buying tobacco products, because they are often told to go to the store to buy tobacco for their parents.

Several countries such as Ireland, Latvia, Estonia, the Netherlands, Finland, Norway, Canada, Australia, Sweden, Portugal, Singapore, Italy, Indonesia, India, Lithuania, Chile, Spain, Iceland, United Kingdom, Slovenia, Turkey and Malta have legislated against smoking in public places, often including bars and restaurants. Restaurateurs have been permitted in some jurisdictions to build designated smoking areas (or to prohibit smoking). In the United States, many states prohibit smoking in restaurants, and some also prohibit smoking in bars. In provinces of Canada, smoking is illegal in indoor workplaces and public places, including bars and restaurants. As of 31 March 2008 Canada has introduced a smoke-free law in all public places, as well as within 10 metres of an entrance to any public place. In Australia, smoke-free laws vary from state to state. In New Zealand and Brazil, smoking is restricted in enclosed public places including bars, restaurants and pubs. Hong Kong restricted smoking on 1 January 2007 in the workplace, public spaces such as restaurants, karaoke rooms, buildings, and public parks (bars which do not admit minors were exempt until 2009). In Romania smoking is illegal in trains, metro stations, public institutions (except where designated, usually outside) and public transport. In Germany, in addition to smoking bans in public buildings and transport, an anti-smoking ordinance for bars and restaurants was implemented in late 2007. A study by the University of Hamburg (Ahlfeldt and Maennig 2010) demonstrates that the smoking ban had, if any, only short run effects on bar and restaurant revenues. In the medium and long run no negative effect was measurable. The results suggest either that the consumption in bars and restaurants is not affected by smoking bans in the long run or that negative revenue effects by smokers are compensated by increasing revenues through non-smokers.[164]

Ignition safety

An indirect public health problem posed by cigarettes is that of accidental fires, usually linked with consumption of alcohol. Enhanced combustion using nitrates was traditionally used but cigarette manufacturers have been silent on this subject claiming at first that a safe cigarette was technically impossible, then that it could only be achieved by modifying the paper. Roll your own cigarettes contain no additives and are fire safe. Numerous

RJ Reynolds), the US' 3rd-largest tobacco company, seems to be ambivalent.[167]

Health warnings

Individual cigarettes in Canada now carry warnings such as "poison in every puff" and "cigarettes cause impotence" in what the government says is an effort to make it "virtually impossible to avoid health warnings altogether".[168]

Gateway drug theory

The relationship between tobacco and other drug use has been well-established, however the nature of this association remains unclear. The two main theories are the

phenotypic causation (gateway) model and the correlated liabilities model. The causation model argues that smoking is a primary influence on future drug use,[169] while the correlated liabilities model argues that smoking and other drug use are predicated on genetic or environmental factors.[170] One study published by the NIH found that tobacco use may be linked to cocaine addiction and marijuana use. The study stated that 90% of adults who used cocaine had smoked cigarettes before (this was for people ages 18–34). This study could support the gateway drug theory.[171]

Cessation

Quitting smoking often involves advice from physicians or social workers,[18] cold turkey, nicotine replacement therapy, contingent vouchers,[172] antidepressants, vaping,[173] hypnosis, self-help (mindfulness meditation),[174] and support groups.

In the United States, about 70% of smokers would like to quit smoking, and 50% report having made an attempt to do so in the past year.[175] Without support, 1% of smokers will successfully quit smoking each year. Physician advice to quit smoking increases the rate to 3% per year.[176] Adding first‐line smoking cessation medications (and some behavioral help), increased quit rates to around 20% of smokers in a year.[177] For cessation of smoking, public participation in health campaigns are important. In Nepal, cardiologist Om Murti Anil has launched smokers are not selfish campaign on the occasion of valentines day. He is using social media to motivate people to sacrifice their smoking habits as gift to their loved ones .[178]
