A tobacco pipe, often called simply a pipe, is a device specifically made to smoke tobacco. It comprises a chamber for the tobacco from which a thin hollow stem (shank) emerges, ending in a mouthpiece. Pipes can range from very simple machine-made briar models to highly prized hand-made artisanal implements made by renowned pipemakers, which are often very expensive collector's items. Pipe smoking is the oldest known traditional form of tobacco smoking.
A cigarette is a narrow cylinder containing burnable material, typically tobacco, that is rolled into thin paper for smoking. Most commercial 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. Some cigarettes may contain a flavoring agent such as menthol. 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 the cigarette as "a drug administration system for the delivery of nicotine in acceptable and attractive form."
Tobacco smoke is an aerosol produced by the incomplete combustion of tobacco during the smoking of cigarettes and other tobacco products. Temperatures in burning cigarettes range from about 400 °C between puffs to about 900 °C during a puff. During the burning of the cigarette tobacco, thousands of chemical substances are generated by combustion, distillation, pyrolysis and pyrosynthesis. Tobacco smoke is used as a fumigant and inhalant.
Tobacco smoking is the practice of burning tobacco and ingesting the smoke that is produced. The smoke may be inhaled, as is done with cigarettes, or simply released from the mouth, as is generally done with pipes and cigars. The practice is believed to have begun as early as 5000–3000 BC in Mesoamerica and South America. Tobacco was introduced to Eurasia in the late 17th century by 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.
The R. J. Reynolds Tobacco Company, is an American tobacco manufacturing company based in Winston-Salem, North Carolina, and headquartered at the RJR Plaza Building. Founded by R. J. Reynolds in 1875, it is the second-largest tobacco company in the U.S.. Nowadays the company is a wholly owned subsidiary of Reynolds American Inc., after merging with the U.S. operations of British American Tobacco in 2004.
A hookah, or shisha, is a single- or multi-stemmed instrument for heating or vaporizing and then smoking either tobacco, flavored tobacco, or sometimes cannabis, hashish, and in the past opium. The smoke is passed through a water basin—often glass-based—before inhalation.
Premier was an American brand of smokeless cigarettes which was owned and manufactured by the R.J. Reynolds Tobacco Company (RJR). Premier was released in the United States in 1988. It was the first commercial heated tobacco product. However, it was difficult to use and tasted unpleasant; as a result, it was unpopular with consumers. A commercial failure, the brand was a significant financial loss for RJR and was quickly taken off the market.
Tar is the name for the resinous, partially combusted particulate matter made by the burning of tobacco and other plant material in the act of smoking. Tar is toxic and damages the smoker's lungs over time through various biochemical and mechanical processes. Tar also damages the mouth by rotting and blackening teeth, damaging gums, and desensitizing taste buds. Tar includes the majority of mutagenic and carcinogenic agents in tobacco smoke. Polycyclic aromatic hydrocarbons (PAH), for example, are genotoxic via epoxidation.
Nicotine marketing is the marketing of nicotine-containing products or use. Traditionally, the tobacco industry markets cigarette smoking, but it is increasingly marketing other products, such as electronic cigarettes and heated tobacco products. Products are marketed through social media, stealth marketing, mass media, and sponsorship. Expenditures on nicotine marketing are in the tens of billions a year; in the US alone, spending was over US$1 million per hour in 2016; in 2003, per-capita marketing spending was $290 per adult smoker, or $45 per inhabitant. Nicotine marketing is increasingly regulated; some forms of nicotine advertising are banned in many countries. The World Health Organization recommends a complete tobacco advertising ban.
Tobacco use has predominantly negative effects on human health and concern about health effects of tobacco has a long history. Research has focused primarily on cigarette tobacco smoking.
Cannabis smoking is the inhalation of smoke or vapors released by heating the flowers, leaves, or extracts of cannabis and releasing the main psychoactive chemical, Δ9-tetrahydrocannabinol (THC), which is absorbed into the bloodstream via the lungs. Archaeological evidence indicates cannabis with high levels of THC was being smoked at least 2,500 years ago.
A cigarette filter, also known as a filter tip, is a component of a cigarette, along with cigarette paper, capsules and adhesives. Filters were introduced in the early 1950s.
A hookah lounge is an establishment where patrons share shisha from a communal hookah or from one placed at each table or a bar.
Tobacco harm reduction (THR) is a public health strategy to lower the health risks to individuals and wider society associated with using tobacco products. It is an example of the concept of harm reduction, a strategy for dealing with the use of drugs. Tobacco smoking is widely acknowledged as a leading cause of illness and death, and reducing smoking is vital to public health.
An electronic cigarette is an electronic device that simulates tobacco smoking. It consists of an atomizer, a power source such as a battery, and a container such as a cartridge or tank. Instead of smoke, the user inhales vapor. As such, using an e-cigarette is often called "vaping". The atomizer is a heating element that atomizes a liquid solution called e-liquid. E-cigarettes are activated by taking a puff or pressing a button. Some look like traditional cigarettes, and most versions are reusable.
The scientific community in United States and Europe are primarily concerned with the possible effect of electronic cigarette use on public health. There is concern among public health experts that e-cigarettes could renormalize smoking, weaken measures to control tobacco, and serve as a gateway for smoking among youth. The public health community is divided over whether to support e-cigarettes, because their safety and efficacy for quitting smoking is unclear. Many in the public health community acknowledge the potential for their quitting smoking and decreasing harm benefits, but there remains a concern over their long-term safety and potential for a new era of users to get addicted to nicotine and then tobacco. There is concern among tobacco control academics and advocates that prevalent universal vaping "will bring its own distinct but as yet unknown health risks in the same way tobacco smoking did, as a result of chronic exposure", among other things.
A heated tobacco product (HTP) is a tobacco product that heats the tobacco at a lower temperature than conventional cigarettes. These products contain nicotine, which is a highly addictive chemical. The heat generates an aerosol or smoke to be inhaled from the tobacco, which contains nicotine and other chemicals. HTPs may also contain additives not found in tobacco, including flavoring chemicals. HTPs generally heat tobacco to temperatures under 600 °C (1100 °F), a lower temperature than conventional cigarettes. HTPs use embedded or external heat sources, heated sealed chambers, or product-specific customized cigarettes. Whereas e-cigarettes are electronic devices that vaporize a liquid containing nicotine, HTPs usually use tobacco in leaf or some other solid form, although there are some hybrid products that can use both solid tobacco and e-liquids. There are various types of HTPs. The two most common designs are those that use an electric battery to heat tobacco leaf and those that use a carbon ember that is lit and then heats the tobacco. There are similar devices that heat cannabis instead of tobacco.
The composition of the emissions generated from heated tobacco products are generally lower than that found in cigarette smoke. This is due to the comparatively low temperatures, the filter systems, and physical design. The composition of what is produced is complex. The main toxicants found in the emissions of cigarette smoke are also found in the emissions of these products in varying concentrations. The aerosol generated contains levels of nicotine and cancer-causing chemicals that are comparable to regular cigarettes. The emissions contained 84% of the nicotine found in regular cigarettes.
