The FDA proposed new regulations on e-cigarettes on Thursday, including rules that would make them off-limits to children under 18 years old.
But many people still might not know exactly what they are, and how they work. While there is some variety amongst the various forms of e-cigs, there are a few basic principles that apply to all of them, no matter their shape or size. All electronic cigarettes contain e-liquid. Propylene glycol and vegetable glycerine produce vapour and throat hit, though while VG produces more vapour, PG produces more throat hit. E-cigarettes are made up of a few main components; an atomiser within a cartridge , a battery, and a mouthpiece.
The atomiser is the most important part of any electronic cigarette, as it is the part that turns the liquid into vapour. It does this by heating a coil that is in contact with the filler material containing the e-liquid. When the liquid is heated, along with the nicotine and flavourings, it creates a vapour, with a much more pleasant aroma than regular cigarette smoke! While it's difficult to make any definitive claims as to the effects e-cigs have on your health, it's obvious that they have some benefits compared to regular smoking:.

The Royal College of Midwives states that "While vaping devices such as electronic cigarettes e-cigs do contain some toxins, they are at "far lower levels than found in tobacco smoke.
If a pregnant woman who has been smoking chooses to use an e-cig and it helps her to quit smoking and stay smokefree, she should be supported to do so. The UK National Health Service says: "If using an e-cigarette helps you to stop smoking, it is much safer for you and your baby than continuing to smoke.
Many women who vape continue to do so during pregnancy because of the perceived safety of e-cigarettes compared to tobacco. The term harm reduction implies any reduction in relative harm from a prior level, even a small reduction such as reducing smoking by one or two cigarettes per day. Tobacco smoke contains known carcinogens, and potentially cancer causing chemicals, but e-cigarette vapor contains less of the potential carcinogens than found in tobacco smoke.
The core concern is that smokers who could have quit entirely will develop an alternative nicotine addiction. A PHE report concluded that hazards associated with products currently on the market are probably low, and apparently much lower than smoking. The available research on the efficacy of e-cigarette use for smoking cessation is limited.
Studies pertaining to their potential impact on smoking reduction are very limited. It is unclear whether e-cigarettes are only helpful for particular types of smokers. Vaping is not clearly more or less effective than regulated nicotine replacement products or 'usual care' for quitting smoking.
It is difficult to reach a general conclusion from e-cigarette use for smoking cessation because there are hundreds of brands and models of e-cigarettes sold that vary in the composition of the liquid. The efficacy and safety of vaping for quitting smoking during pregnancy is unknown. Research has not yet provided a consensus on the risks of e-cigarette use. The cytotoxicity of e-liquids varies,  and contamination with various chemicals have been detected in the liquid.
E-cigarettes create vapor that consists of fine and ultrafine particles of particulate matter , with the majority of particles in the ultrafine range. Nicotine, a key ingredient  in most e-liquids, [notes 5]  is well-recognized as one of the most addictive substances, as addictive as heroin and cocaine. When nicotine intake stops, the upregulated nicotinic acetylcholine receptors induce withdrawal symptoms. A American Academy of Pediatrics AAP policy statement stressed "the potential for these products to addict a new generation of youth to nicotine and reverse more than 50 years of public health gains in tobacco control.
Following the possibility of nicotine addiction via e-cigarettes, there is concern that children may start smoking cigarettes. Because of overlap with tobacco laws and medical drug policies, e-cigarette legislation is being debated in many countries. The scientific community in US and Europe are primarily concerned with their possible effect on public health. Medical organizations differ in their views about the health implications of vaping. It is commonly stated that the modern e-cigarette was invented in by Chinese pharmacist Hon Lik , but tobacco companies had been developing nicotine aerosol generation devices since as early as In , Joseph Robinson applied for a patent for an electronic vaporizer to be used with medicinal compounds.
The earliest e-cigarette can be traced to American Herbert A. Gilbert,  who in applied for a patent for "a smokeless non-tobacco cigarette" that involved "replacing burning tobacco and paper with heated, moist, flavored air". Hon Lik , a Chinese pharmacist and inventor, who worked as a research pharmacist for a company producing ginseng products,  is frequently credited with the invention of the modern e-cigarette.
Hon Lik registered a patent for the modern e-cigarette design in Initially, their performance did not meet the expectations of users. In , a consumer created an e-cigarette called the screwdriver. International tobacco companies dismissed e-cigarettes as a fad at first.
Consumers have shown passionate support for e-cigarettes that other nicotine replacement products did not receive. By , a subculture had emerged calling itself "the vaping community". Contempt for Big Tobacco is part of vaping culture. A popular vaporizer used by American youth is the Juul.
Large gatherings of vapers, called vape meets, take place around the US. A subclass of vapers configure their atomizers to produce large amounts of vapor by using low-resistance heating coils. Regulation of e-cigarettes varies across countries and states, ranging from no regulation to banning them entirely. The legal status of e-cigarettes is currently pending in many countries.
In February the European Parliament passed regulations requiring standardization and quality control for liquids and vaporizers, disclosure of ingredients in liquids, and child-proofing and tamper-proofing for liquid packaging. E-cigarettes containing nicotine have been listed as drug delivery devices in a number of countries, and the marketing of such products has been restricted or put on hold until safety and efficacy clinical trials are conclusive.
Multiple reports from the U. Fire Administration conclude that electronic cigarettes have been combusting and injuring people and surrounding areas. Fire Administration noted in their report that electronic cigarettes are not created by Big Tobacco or other tobacco companies, but by independent factories that have little quality control. Most incidents in which electronic cigarettes have been known to explode, occurred when the device itself is charging, usually within 10 minutes.
Multiple case studies have shown that electronic cigarettes are at risk of this while they are charging. The U. The first issue would be the device causing a fire while charging and while in use, in which a person may be harmed but they can relatively quickly put out the fire with minimal damage to them and their surroundings.
Some of the incidents that the U. In 10 incidents, the fire spread was major and involved significant portions of a building and required suppression by the fire department,". Fire Administration also notes that in most cases, when the device has combusted, the fire produced spreads to nearby clothing, carpets, drapes, etc. Large tobacco companies have greatly increased their marketing efforts.
They are marketed to men, women, and children as being safer than traditional cigarettes. While advertising of tobacco products is banned in most countries, television and radio e-cigarette advertising in several countries may be indirectly encouraging traditional cigarette use. Celebrity endorsements are used to encourage e-cigarette use. E-cigarettes are heavily promoted across all media outlets. The number of e-cigarettes sold increased every year from to The leading seller in the e-cigarette market in the US is the Juul e-cigarette,  which was introduced in June In Canada, e-cigarettes had an estimated value of million CAD in By the e-cigarette market had only reached a twentieth of the size of the tobacco market in the UK.
Compared to traditional cigarettes, reusable e-cigarettes do not create waste and potential litter from every use in the form of discarded cigarette butts. Although some brands have begun recycling services for their e-cigarette cartridges and batteries, the prevalence of recycling is unknown. Other devices to deliver inhaled nicotine have been developed.
British American Tobacco, through their subsidiary Nicoventures, licensed a nicotine delivery system based on existing asthma inhaler technology from UK-based healthcare company Kind Consumer. BLOW started selling e-hookahs, an electronic version of the hookah , in From Wikipedia, the free encyclopedia.
