Rev Mal Respir ; Introduction For several decades a more peripheral distribution of the broncho-pulmonary tobacco-related pathologies has been observed. Methods The aim of this study is to examine whether changes in the particle size of cigarette smoke resulting from new manufacturing technologies could play a part in the observed epidemiological changes through a more distal deposition of smoke particles in the airways. Using a smoking machine and a low pressure electrostatic impactor we measured the particle size of the smoke from six different types of cigarette, representing the older and more modern manufacturing techniques.

Cigarette filterVIDEO ON THE TOPIC: How It Is Made - Cigarettes
Decades of research have thoroughly documented the health problems that result from inhaling tobacco smoke — more than a dozen different types of cancer, heart disease, stroke, emphysema and other respiratory diseases, among others.
Are these risks an inevitable part of smoking? Or is there a way of creating safe cigarettes without any of these hazards? Tobacco smoke is a complex cocktail of at least 4, chemicals including at least 70 known carcinogens. Journalist Will Storr recently documented a history of bungled attempts to create a safer cigarette , from one that passed the carcinogenic smoke through a filter made of another carcinogen — asbestos — to another that heated tobacco rather than burning it, but tasted of sulphur, charcoal, and burning plastic.
The problem is that no single step in the production or consumption process fills cigarette smoke with its dangerous constituents. Some constituents are in the tobacco leaves themselves at the point of harvesting. The plants can absorb metals and metalloids like arsenic and cadmium from fertilisers and the surrounding soil, while sticky hairs on their leaves can gather particles from the air, including radioactive elements like polonium When the harvested leaves are cured and dried, compounds within them are converted into tobacco-specific nitrosamines TSNAs , a class of well-known and intensely studied carcinogens.
And, they cause similar patterns of DNA damage to those seen in actual tumours. The route of exposure also matters. Many of the chemicals in tobacco smoke are also found in other everyday sources, including foods. There are some measures that could individually reduce the number of carcinogens in smoke: modifying the blend of tobacco; refining the curing process; including charcoal filters to absorb some of the volatiles; and so on.
It increases heart rate, constricts blood vessels, and contributes to high levels of cholesterol. But both of these claims come from studies in lab-grown cells. These cigarettes were tested with machines that, sure enough, measured a lower concentration of tar in the ensuing smoke.
As the smoke from these brands also contained less nicotine, smokers would get their fix by taking longer drags, smoking more frequently , or simply blocking the filters with their fingers. Smokeless tobacco products fare little better. Even though they are sucked, chewed and sniffed, and never set on fire, they still contain many of the same carcinogens as cigarettes, and have been linked to mouth, oesophageal and pancreatic cancers.
Indeed, some recent studies have suggested that snus users have a higher risk of pancreatic cancer , and a higher risk of dying from cancer. His concerns are that snus could make it harder for active smokers to give up their habit by fuelling nicotine addiction, or act as a gateway drug that entices non-smokers to start. The same arguments apply to e-cigarettes — battery-powered devices that look like cigarettes, and release a nicotine vapour without any of the accompanying carcinogens.
An analysis from the US Food and Drug Administration showed that some still contained detectable traces of nitrosamines. The use of both snus and e-cigarettes will probably remain highly controversial, even after more data comes in. This reflects a tension in public health circles : given smoking is so addictive and damaging, is it acceptable or even ethical to reduce that harm by advocating products that are safer, but still not safe?
In a world where tobacco never existed, these arguments would be moot. But that world does not exist; what do we do in this one?

Filter manufacturers and cigarette companies are inextricably intertwined and depend on each other. Cigarette sales volumes also affect filter suppliers and they have to come up with ingenious solutions to stay competitive. When it comes to modern cigarettes, few consumers waste a thought on what is arguably the most high-tech component: the filter. Although non-filtered cigarette brands are still around, filter-tipped cigarettes reign supreme and currently make up the absolute majority of all cigarettes sold worldwide. While consumers may take filters for granted, they are in fact little technological marvels designed to not only enhance the overall smoking experience but to also remove varying proportions of larger smoke particles and water-soluble compounds like aldehydes and phenols. Tobacco companies have the choice of being supplied with ready-to-use filter rods from a myriad of manufacturing companies or produce their filters in-house, taking deliveries of raw materials such as cellulose acetate CA , polypropylene PP or — since relatively recently - polylactic acid PLA tow in addition to a range of plug wraps and tipping papers. Both options have advantages and disadvantages.

This application claims the benefit of International Application No. Until a few years ago, shop-bought filter-tipped cigarettes comprised a filter made solely of one portion of cellulose acetate formed from a strip of cellulose acetate, which is stretched, impregnated with plasticizing additives, and rolled to form a cylindrical rod which is then wrapped in a sheet of paper material. A filter made of a single portion of cellulose acetate is capable of blocking and retaining course particulate and moisture present in tobacco smoke, but fails to adequately block volatile substances in the smoke. For which reason, a cigarette filter has recently been proposed, in which a further filtering portion, comprising active-carbon granules, is interposed between two portions of cellulose acetate.
The present application is a continuation of application Ser. This application claims the benefit of U. The present invention relates to filter-tipped smoking articles such as filtered cigarettes, and in particular, to cigarette filters containing a carbon material. Filter-tipped smoking articles, particularly cigarettes, generally comprise a tobacco rod, a filter and a band of tipping paper attaching the filter to tobacco rod. The tobacco rod generally comprises a column of shredded tobacco e. Ventilation of mainstream smoke is achieved by provision of a row or rows of perforations through the tipping paper at a location along the filter plug. Ventilation provides dilution of drawn mainstream smoke with ambient air to reduce the delivery level of tar per puff. During smoking, a smoker draws mainstream smoke from the coal at the lit end of the cigarette. The drawn cigarette smoke first enters the upstream filter portion of the filter and then passes through the downstream portion adjacent to the buccal end of the cigarette filter.

The present application claims the benefit of provisional application Ser. The present invention relates to cigarette filters, and more particularly to cigarette filters that include vacuum deposited particulate filter material. A variety of cigarette filters have been proposed over the years, and many of these filters include granular filter material particularly in so-called plug-space-plug filters. In these filters, spaced apart plugs, usually made of cellulose acetate, define a cavity therebetween which is filled with granulated material, such as granulated carbon, for example. The filters are attached to wrapped tobacco rods with tipping paper to produce the finished cigarettes. In many instances, the granulated material is vertically filled into the cavity during filter manufacture. It is important that the cavity between the cellulose acetate plugs be sufficiently filled with particulate material so that tobacco smoke comes into contact with the material as it is drawn through the filter. Insufficient fill causes so-called channeling of the smoke as it passes through the cavity which results in less efficient filtering. One of the primary objects of the present invention is a cigarette filter that includes a sufficiently packed bed of particulate material. Another object of the present invention is the feature of horizontally depositing particulate material into the cavity of a cigarette filter in a manner that produces a packed bed of material with improved filtering efficiency.
Filters: A Sometimes Overlooked High-Tech Cigarette Component
This application is a continuation-in-part of U. This invention relates to an improved method of manufacturing a filter cigarette with a tipping paper having lip release properties. More particularly, the invention relates to a method of imparting lip release properties to a base tipping paper during the production of the base tipping paper in a paper machine followed by manufacturing the cigarette itself. Tipping paper is the outermost paper of the filter section of a cigarette and is used to join the tobacco-containing section to the filter section. It is important to a cigarette smoker that the cigarette filter section does not adhere to his lips.
