This caused deaths with 1, people injured. 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.

This retail display ban includes noncigarette products such as cigars and blunt wraps. 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. In , Iceland became the first country to enforce graphic warnings on cigarette packaging. The only feature that differentiates one brand from another is the product name in a standard color, position, font size, and style.

This took effect on December 1, 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. 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. 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. 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 s, 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". The most common tobacco byproducts include:. 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 [81] and the plant stem.

A recipe-specified combination of brightleaf, burley-leaf, and oriental-leaf tobacco is mixed with various additives to improve its flavors. 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". Finally, the tobacco mixture is filled into cigarette tubes and packaged.

A list of cigarette additives , created by five major American cigarette companies, was approved by the Department of Health and Human Services in April 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 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. 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 [91]. The United States Tobacco Taxation Bureau defines a cigarette tube as "Cigarette paper made into a hollow cylinder for use in making cigarettes. 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. The common name for the remains of a cigarette after smoking is a cigarette butt.

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. In a trial the city of Vancouver , British Columbia , partnered with TerraCycle to create a system for recycling of cigarette butts. Cigarette filters are made up of thousands of polymer chains of cellulose acetate , which has the chemical structure shown to the right.

Once discarded into the environment, the filters create a large waste problem. Cigarette filters are the most common form of litter in the world, as approximately 5. Discarded cigarette filters usually end up in the water system through drainage ditches and are transported by rivers and other waterways to the ocean. In the International Coastal Cleanup, cigarettes and cigarette butts constituted After a cigarette is smoked, the filter retains some of the chemicals, and some of which are considered carcinogenic.

Researchers instead focus on the whole cigarette filter and its LD This allows for a simpler study of the toxicity of cigarettes filters. Toxic chemicals are not the only human health concern to take into considerations; the others are cellulose acetate and carbon particles that are breathed in while smoking. These particles are suspected of causing lung damage.

Under certain growing conditions, plants on average grow taller and have longer roots than those exposed to cigarette filters in the soil. A connection exists between cigarette filters introduced to soil and the depletion of some soil nutrients over a period time. Another health concern to the environment is not only the toxic carcinogens that are harmful to the wildlife, but also the filters themselves pose an ingestion risk to wildlife that may presume filter litter as food.

This could lead to toxin build-up bioaccumulation in the food chain and have long reaching negative effects. Smoldering cigarette filters have also been blamed for triggering fires from residential areas [] to major wildfires and bushfires which has caused major property damage and also death [] [] [] as well as disruption to services by triggering alarms and warning systems. Once in the environment, cellulose acetate can go through biodegradation and photodegradation.

This variance in rate and resistance to biodegradation in many conditions is a factor in littering [] and environmental damage. The first step in the biodegradation of cellulose acetate is the deactylation of the acetate from the polymer chain which is the opposite of acetylation. Deacetylation can be performed by either chemical hydrolysis or acetylesterase.

Chemical hydrolysis is the cleavage of a chemical bond by addition of water. In the reaction, water H 2 O reacts with the acetic ester functional group attached the cellulose polymer chain and forms an alcohol and acetate. The alcohol is simply the cellulose polymer chain with the acetate replaced with an alcohol group.

The second reaction is exactly the same as chemical hydrolysis with the exception of the use of an acetylesterase enzyme. The enzyme, found in most plants, catalyzes the chemical reaction shown below. In the case of the enzymatic reaction, the two substrates reactants are again acetic ester and H 2 O, the two products of the reaction are alcohol and acetate.

This reaction is exactly the same as the chemical hydrolysis. Both of these products are perfectly fine in the environment. Once the acetate group is removed from the cellulose chain, the polymer can be readily degraded by cellulase , which is another enzyme found in fungi , bacteria , and protozoans.

Cellulases break down the cellulose molecule into monosaccharides "simple sugars" such as beta- glucose , or shorter polysaccharides and oligosaccharides. These simple sugars are not harmful to the environment and are in fact are a useful product for many plants and animals. The breakdown of cellulose is of interest in the field of biofuel.

The duration of the biodegradation process is cited as taking as little as one month [] to as long as 15 years or more, depending on the environmental conditions. The major factor that affects the biodegradation duration is the availability of acetylesterase and cellulase enzymes. Without these enzymes, biodegradation only occurs through chemical hydrolysis and stops there.

Temperature is another major factor, if the organisms that contain the enzymes are too cold to grow, then biodegradation is severely hindered. Availability of oxygen in the environment also affects the degradation. Cellulose acetate is degraded within 2—3 weeks under aerobic assay systems of in vitro enrichment cultivation techniques and an activated sludge wastewater treatment system. Thus, filters last longer in places with low oxygen concentration ex. Overall, the biodegraditon process of cellulose acetate is not an instantaneous process.

The other process of degradation is photodegradation , which is when a molecular bond is broken by the absorption of photon radiation i. Thus, the primary photodegradation of cellulose acetate is considered insignificant to the total degradation process, since cellulose acetate and its impurities absorb light at shorter wavelengths.

Research is focused on the secondary mechanisms of photodegradation of cellulose acetate to help make up for some of the limitations of biodegradation. The secondary mechanisms would be the addition of a compound to the filters that would be able to absorb natural light and use it to start the degradation process. The main two areas of research are in photocatalytic oxidation [] and photosensitized degradation.

Photosensitized degradation, though, uses a species that absorbs radiation and transfers the energy to the cellulose acetate to start the degradation process. Several options are available to help reduce the environmental impact of cigarette butts. Proper disposal into receptacles leads to decreased numbers found in the environment and their effect on the environment.

The next option is using cigarette packs with a compartment in which to discard cigarette butts, implementing monetary deposits on filters, increasing the availability of butt receptacles, and expanding public education. It may even be possible to ban the sale of filtered cigarettes altogether on the basis of their adverse environmental impact. One research group in South Korea has developed a simple one-step process that converts the cellulose acetate in discarded cigarette filters into a high-performing material that could be integrated into computers, handheld devices, electrical vehicles, and wind turbines to store energy.

These materials have demonstrated superior performance as compared to commercially available carbon, grapheme, and carbon nanotubes. The product is showing high promise as a green alternative for the waste problem. Smoking has become less popular, but is still a large public health problem globally. The significant reductions in smoking rates in the United States, United Kingdom, Australia, Brazil, and other countries that implemented strong tobacco control programs [ according to whom?

The Chinese market now consumes more cigarettes than all other low- and middle-income countries combined. Other regions are increasingly playing larger roles in the growing global smoking epidemic. Due to its recent dynamic economic development and continued population growth, Africa presents the greatest risk in terms of future growth in tobacco use. Within countries, patterns of cigarette consumption also can vary widely. For example, in many of the countries where few women smoke, smoking rates are often high in males e.

By contrast, in most developed countries, female smoking rates are typically only a few percentage points below those of males. In many high and middle income countries lower socioeconomic status is a strong predictor of smoking. Other countries have considered similar measures. In New Zealand, a bill has been presented to parliament in which the government's associate health minister said "takes away the last means of promoting tobacco as a desirable product.

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. Due to recent U. Research shows that smoking "light" or "low-tar" cigarettes is just as harmful as smoking other cigarettes.

A very strong argument can be made about the association between adolescent exposure to nicotine by smoking conventional cigarettes and the subsequent onset of using other dependence-producing substances. The harm from smoking comes from the many toxic chemicals in the natural tobacco leaf and those formed in smoke from burning tobacco.

People keep smoking because the nicotine , the primary psychoactive chemical in cigarettes, is highly addictive. Smoking harms nearly every organ of the body. Smoking leads most commonly to diseases affecting the heart, liver, and lungs, being a major risk factor for heart attacks , strokes , chronic obstructive pulmonary disease COPD including emphysema and chronic bronchitis , and cancer particularly lung cancer , cancers of the larynx and mouth , and pancreatic cancer.

It also causes peripheral vascular disease and hypertension. Children born to women who smoke during pregnancy are at higher risk of congenital disorders, cancer, respiratory disease, and sudden death. On average, each cigarette smoked is estimated to shorten life by 11 minutes. The World Health Organization estimates that tobacco kills 8 million people each year as of [] and million deaths over the course of the 20th century.

The most important chemical compounds causing cancer are those that produce DNA damage since such damage appears to be the primary underlying cause of cancer. The seven most important carcinogens in tobacco smoke are shown in the table, along with DNA alterations they cause. Second-hand smoke is a mixture of smoke from the burning end of a cigarette and the smoke exhaled from the lungs of smokers.

It is involuntarily inhaled, lingers in the air for hours after cigarettes have been extinguished, and can cause a wide range of adverse health effects, including cancer, respiratory infections , and asthma. Second-hand smoke has been estimated to cause 38, deaths per year, of which 3, are deaths from lung cancer in nonsmokers. Smoking cessation quitting smoking is the process of discontinuing the practice of inhaling a smoked substance.

Smoking cessation can be achieved with or without assistance from healthcare professionals or the use of medications. Although stopping smoking can cause short-term side effects such as reversible weight gain, smoking cessation services and activities are cost-effective because of the positive health benefits.

At the University of Buffalo, researchers found out that fruit and vegetable consumption can help a smoker cut down or even quit smoking []. Tobacco contains nicotine. Smoking cigarettes can lead to nicotine addiction. The number of nicotinic receptors in the brain returns to the level of a nonsmoker between 6 and 12 weeks after quitting. 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.

The benefits and the health risks of e-cigarettes are uncertain. E-cigarettes create vapor made of fine and ultrafine particles of particulate matter , [] which have been found to contain propylene glycol, glycerin, nicotine, flavors, small amounts of toxicants , [] carcinogens , [] and heavy metals , as well as metal nanoparticles , and other substances.
