Cigarettes
A cigarette is a narrow cylinder containing a combustible material, typically tobacco, that is rolled into thin paper for smoking. The cigarette is ignited at one end, causing it to smolder; the resulting smoke is orally inhaled via the opposite end. Cigarette smoking is the most common method of tobacco consumption. The term ''cigarette'', as commonly used, refers to a tobacco cigarette, but the word is sometimes used to refer to other substances, such as a cannabis cigarette or a herbal cigarette. A cigarette is distinguished from a cigar by its usually smaller size, use of processed leaf, different smoking method, and paper wrapping, which is typically white. There are significant negative health effects from smoking cigarettes such as cancer, chronic obstructive pulmonary disease (COPD), heart disease, birth defects, and other health problems relating to nearly every organ of the body. Most modern cigarettes are filtered, although this does not make the smoke inhaled f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Cigarettes

It consists of an Construction of electronic cigarettes#Atomizer and tank, atomizer, a power source such as a battery, and a container such as a cartridge or tank. Instead of tobacco smoke, smoke, the user inhales Vaporizer (inhalation device), vapor. As such, using an e-cigarette is often called "vaping". The atomizer is a heating element that vaporizes a Solution (chemistry)#Liquid solutions, liquid solution called construction of electronic cigarettes#E-cigarette liquid, e-liquid that cools into an aerosol of tiny droplets, vapor and air. The vapor mainly comprises propylene glycol and/or glycerin, usually with nicotine and flavoring. Its composition of electronic cigarette aerosol, exact composition varies, and depends on matters such as user behavior. E-cigarettes are activated by taking a puff or pressing a button.

Health Effects Of Electronic Cigarettes
The health effects of electronic cigarettes (e-cigarettes) are less harmful than those of smoking, but worse than not smoking at all. However, health effects are a function of inhaled materials, of associated behavior changes (notably traditional cigarette smoking), of how and how often the products are used, over what period, manufacturing/distribution quality control, marketing, the regulatory environment, and the actual user population. A 2025 US study that analyzed data from the National Vital Statistics System (NVSS), the Behavioral Risk Factor Surveillance System (BRFSS), the National Health Interview Survey (NHIS), and the National Survey on Drug Use and Health (NSDUH) concluded that e-cigarettes had preserved 677,000 Quality-adjusted life year, life–years from 2011 to 2019. A 2025 review of 39 studies found "no significant incident or prevalent risk" of cancer from vaping. The public health community is divided over the use of these devices to reduce/prevent smoking. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Construction Of Electronic Cigarettes
An electronic cigarette is a handheld battery-powered vaporizer that simulates smoking, but without tobacco combustion. E-cigarette components include a mouthpiece (drip tip), a cartridge (liquid storage area), a heating element/ atomizer, a microprocessor, a battery, and some of them have an LED light on the end. An atomizer consists of a small heating element, or coil, that vaporizes e-liquid and a wicking material that draws liquid onto the coil. When the user inhales, a flow sensor activates the heating element that atomizes the liquid solution; most devices are manually activated by a push-button. The e-liquid reaches a temperature of roughly within a chamber to create an aerosolized vapor. The user inhales an aerosol, which is commonly but inaccurately called vapor, rather than cigarette smoke. Vaping is different from smoking, but there are some similarities, including the hand-to-mouth action of smoking and an aerosol that looks like cigarette smoke. The aerosol p ...

Health Effects Of Tobacco
Tobacco products, especially when smoked or used orally, have serious negative effects on human health. Smoking and smokeless tobacco use are the single greatest causes of preventable death globally. Half of tobacco users die from complications related to such use. Current smokers are estimated to die an average of 10 years earlier than non-smokers. The World Health Organization estimates that, in total, about 8 million people die from tobacco-related causes, including 1.3 million non-smokers due to secondhand smoke. It is further estimated to have caused 100 million deaths in the 20th century. Tobacco smoke contains over List of cigarette smoke carcinogens, 70 chemicals, known as carcinogens, that cause cancer. It also contains nicotine, a highly Addiction, addictive psychoactive drug. When tobacco is smoked, the nicotine causes Physical dependence, physical and psychological dependency. Cigarettes sold in least developed countries have higher tar content and are less likely to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbal Cigarette
An herbal cigarette (also called a tobacco-free cigarette or nicotine-free cigarette) is a cigarette that usually does not contain any tobacco or nicotine, instead being composed of a mixture of various herbs and/or other plant material. However, Chinese herbal cigarettes contain tobacco and nicotine with herbs added, unlike European and North American herbal cigarettes which have tobacco and nicotine omitted. Like herbal smokeless tobacco, they are often used as a substitute for standard tobacco products (primarily cigarettes). Herbal cigarettes are often advertised as a smoking cessation aid. They are also used in acting scenes by performers who are non-smokers, or where anti-smoking legislation prohibits the use of tobacco in public spaces. Herbal cigarettes can carry carcinogens. Construction Paper and filter Herbal cigarettes are most often made using standard-issue rolling papers and cigarette filters, bundled together.

Nicotine
Nicotine is a natural product, naturally produced alkaloid in the nightshade family of plants (most predominantly in tobacco and ''Duboisia hopwoodii'') and is widely used recreational drug use, recreationally as a stimulant and anxiolytic. As a pharmaceutical drug, it is used for smoking cessation to relieve drug withdrawal, withdrawal symptoms. Nicotine acts as a receptor agonist at most nicotinic acetylcholine receptors (nAChRs), except at two nicotinic receptor subunits (nAChRα9 and nAChRα10) where it acts as a receptor antagonist. Nicotine constitutes approximately 0.6–3.0% of the dry weight of tobacco. Nicotine is also present at Parts-per notation, ppb concentrations in edible plants in the family Solanaceae, including potatoes, tomatoes, and eggplants, though sources disagree on whether this has any biological significance to human consumers. It functions as an plant defense against herbivory, antiherbivore toxin; consequently, nicotine was widely used as an insecti ...

Cigarette Filter
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. Filters may be made from plastic cellulose acetate fiber, paper or activated charcoal (either as a cavity filter or embedded into the plastic cellulose acetate fibers). Macroporous phenol-formaldehyde resins and asbestos have also been used. The plastic cellulose acetate filter and paper modify the particulate smoke phase by particle retention (filtration), and finely divided carbon modifies the gaseous phase (adsorption). Filters are intended to reduce the harm caused by smoking by reducing harmful chemicals inhaled by smokers. While laboratory tests show a reduction of " tar" and nicotine in cigarette smoke, filters are ineffective at removing gases of low molecular weight, such as carbon monoxide. Most of these measured reductions occur only when the cigarette is smoked on a smoking machine; when smo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tobacco
Tobacco is the common name of several plants in the genus '' Nicotiana'' of the family Solanaceae, and the general term for any product prepared from the cured leaves of these plants. More than 70 species of tobacco are known, but the chief commercial crop is ''N. tabacum''. The more potent variant ''N. rustica'' is also used in some countries. Dried tobacco leaves are mainly used for smoking in cigarettes and cigars, as well as pipes and shishas. They can also be consumed as snuff, chewing tobacco, dipping tobacco, and snus. Tobacco contains the highly addictive stimulant alkaloid nicotine as well as harmala alkaloids. Tobacco use is a cause or risk factor for many deadly diseases, especially those affecting the heart, liver, and lungs, as well as many cancers. In 2008, the World Health Organization named tobacco use as the world's single greatest preventable cause of death. Etymology The English word 'tobacco' originates from the Spanish word ''taba ...

Smoking
Smoking is a practice in which a substance is combusted, and the resulting smoke is typically inhaled to be tasted and absorbed into the bloodstream of a person. Most commonly, the substance used is the dried leaves of the tobacco plant, which have been rolled with a small rectangle of paper into an elongated cylinder called a cigarette. Other forms of smoking include the use of a smoking pipe or a bong. Smoking is primarily practised as a route of administration for psychoactive chemicals because the active substances within the burnt dried plant leaves vaporize and can be airborne-delivered into the respiratory tract, where they are rapidly absorbed into the bloodstream of the lungs and then reach the central nervous system. In the case of tobacco smoking, these active substances are a mixture of aerosol particles that includes the pharmacologically active alkaloid nicotine, which stimulates the nicotinic acetylcholine receptors in the brain. Other notable active ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cigar
A cigar is a rolled bundle of dried and Fermentation, fermented tobacco leaves made to be Tobacco smoking, smoked. Cigars are produced in a variety of sizes and shapes. Since the 20th century, almost all cigars are made of three distinct components: the filler, the binder leaf which holds the filler together, and a wrapper leaf, which is often the highest quality leaf used. Often there will be a cigar band printed with the cigar manufacturer's logo. Modern cigars can come with two or more bands, especially Cuban cigars, showing Limited Edition (''Edición Limitada'') bands displaying the year of production. Cigar tobacco is grown in significant quantities primarily in Brazil, Central America (Costa Rica, Ecuador, Guatemala, Honduras, Mexico, Nicaragua, and Panama), and the islands of the Caribbean (Cuba, the Dominican Republic, Haiti, and Puerto Rico); it is also produced in the Eastern United States (mostly in Florida, Kentucky, Tennessee, and Virginia) and in the Mediterrane ...
