E-cig
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 vaporizes a liquid solution called e-liquid, which quickly cools into an aerosol of tiny droplets, vapor and air. E-cigarettes are activated by taking a puff or pressing a button. Some look like traditional cigarettes, and most kinds are reusable. The vapor mainly comprises propylene glycol and/or glycerin, usually with nicotine and flavoring. Its exact composition varies, and depends on several things including user behavior. Vaping is likely much less harmful than smoking. E-cigarette vapor contains fewer toxins than cigarette smoke. It contains traces of harmful substances not found in cigarette smoke. Nicotine is highly addictive. Users beco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Composition Of Electronic Cigarette Aerosol
The chemical composition of the electronic cigarette aerosol varies across and within manufacturers. Limited data exists regarding their chemistry. However, researchers at Johns Hopkins University analyzed the vape clouds of popular brands such as Juul and Vuse, and found "nearly 2,000 chemicals, the vast majority of which are unidentified." The aerosol of e-cigarettes is generated when the e-liquid comes in contact with a coil heated to a temperature of roughly within a chamber, which is thought to cause pyrolysis of the e-liquid and could also lead to decomposition of other liquid ingredients. The aerosol (mist) produced by an e-cigarette is commonly but inaccurately called vapor. E-cigarettes simulate the action of smoking, but without tobacco combustion. The e-cigarette aerosol looks like cigarette smoke to some extent. E-cigarettes do not produce aerosol between puffs. The e-cigarette aerosol usually contains propylene glycol, glycerin, nicotine, flavors, aroma transporte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Construction Of Electronic Cigarettes
An electronic cigarette is a handheld battery (electricity), battery-powered Vaporizer (inhalation device), vaporizer that simulates tobacco smoking, smoking, but without tobacco combustion. E-cigarette components include a mouthpiece (drip tip), a cartridge (liquid storage area), a heating element/atomizer nozzle, atomizer, a microprocessor, a battery, and some of them have an LED lamp, LED light on the end. An atomizer consists of a small heating element, or coil, that vaporizes e-liquid and a capillary action, wicking material that draws liquid onto the coil. When the user inhales a flow sensor activates the heating element that atomizes the Solution (chemistry)#Liquid solutions, 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 smo ...

Cigarette
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 an herbal cigarette. A cigarette is distinguished from a cigar by its usually smaller size, use of processed leaf, and paper wrapping, which is typically white. Since the 1920s, scientists and doctors have been able to link smoking with respiratory illness. Researchers have identified negative health effects from smoking cigarettes such as cancer, chronic obstructive pulmonary disease (COPD), heart disease, and other health problems relating to nearly every organ of the body. Nicotine, the psycho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vaporizer (inhalation Device)
A vaporizer or vaporiser, colloquially known as a vape, is a device used to vaporize substances for inhalation. Plant substances can be used, commonly cannabis, tobacco, or other herbs or blends of essential oil. However, they can also be filled with a combination propylene glycol, glycerin, and drugs such as nicotine (e.g. extract from tobacco) or tetrahydrocannabinol as a liquid solution. Vaporizers contain various forms of extraction chambers including straight bore, venturi, or sequential venturi, and are made of materials such as metal or glass. The extracted vapor may be collected in an inflatable bag, or inhaled directly through a hose or pipe. When used properly, cooler temperatures due to lack of combustion result in significantly more efficient extraction of the ingredients. Hence, the irritating and harmful effects of smoking are heavily reduced, as is its secondhand smoke. Cannabis vaporizers Cannabis flower is commonly consumed using a dry herb vaporizer. The cann ...

Tobacco Products Directive
The Tobacco Products Directive (TPD) or European Tobacco Products Directive (EUTPD) (2014/40/EU) is a directive of the European Union which places limits on the sale and merchandising of tobacco and tobacco related products in the EU. The TPD aims to improve the functioning of the internal market for tobacco and related products, while ensuring a high level of health protection for European citizens. Based on the proposal of the European Commission the Directive entered into force on 19 May 2014 and became applicable in the EU Member States on 20 May 2016. This Directive applies to the manufacture, presentation, and sale of tobacco related products including cigarettes, roll your own tobacco, pipe tobacco, cigars, cigarillos, smokeless tobacco, electronic cigarettes, and herbal products for smoking. To address this situation, the European Union and its Member States have taken various tobacco control measures in the form of legislation, recommendations and information campaigns. ...

Nicotine Salt
Nicotine salts are salts formed from nicotine and an acid. They are found naturally in tobacco leaves. Various acids can be used, leading to different conjugate bases paired with the ammonium form of nicotine. Research Research on nicotine salts is limited. Possible health risks of persistent inhalation of high levels of nicotine salts are not known. "Juul products use nicotine salts, which can lead to much more available nicotine," Principal Deputy Director Dr. Anne Schuchat of the Centers for Disease Control and Prevention (CDC) stated in September 2019. She also stated that the nicotine salts "cross the blood brain barrier and lead to potentially more effect on the developing brain in adolescents." Types A nicotine base and a weak acid such as benzoic acid or levulinic acid is used to form a nicotine salt. Across a sample of 23 nicotine salts available for public purchase, the three most common acids used in the formation of nicotine salts were lactic acid, benzoic acid and ...
