What are e-cigarettes ?
E-cigarettes, known as electronic cigarettes and vaporizer cigarettes are devices that emit doses of vaporized nicotine that you inhale it. The device works with battery and can also emit non-nicotine vaporized solutions. Manufacturers claim they are an alternative for tobacco smokers who don’t want to inhale smoke. Tobacco smoke contains over 4,000 different chemicals, many of which are dangerous for human health.
Manufacturers and many users say the e-cigarette provides a similar sensation to inhaling tobacco smoke although, there is no smoke.
E-cigarettes are long-shaped tubes, like a cigarette, cigar or pipe. Most of them are reusable with replaceable and refillable cartridges. And a few of them are throw-away ones – disposable e-cigarettes. Most of them are now automatic – as the user sucks on it, a sensor activates a heating element that vaporizes a liquid. The user can determine whether or not to have nicotine in the flavored liquid. In older ones, there is a minute button which turns the heating element on and off. An LED shows whether the device has been activated when the user inhales.they also known as green smoke!
Don’t worry about misplacing your lighter or your matches if you’re smoking an e-cigarette — there’s nothing to light. Instead, e-cigarettes run on a lithium battery; each also contains a vaporization chamber and a cartridge filled with liquid solution. When you puff on your e-cig as you would a regular cigarette, the battery turns on the device to heat the liquid and vaporize it. Some e-cigarettes have an LED tip that glows red. As they don’t burn tobacco, there’s no smoke, no carbon monoxide and no odor; what you inhale is only vapor.
E-cigarettes are free of smoke and tobacco, but they contain nicotine. The liquid in e-cigarettes usually contains nicotine, flavorings, propylene glycol, and other things. The amount of nicotine depends on the liquid-nicotine cartridge you put in the device. Some products contain nicotine the same as tobacco cigarettes, while others contain levels closer to that of a light or ultralight cigarette. There are also cartridges available that have flavored liquid without nicotine.
Cigarette smoke contains more than 7,000 chemicals, and 69 are known carcinogens. Both regular and electronic cigarettes are toxic. Liquid nicotine is extracted from tobacco, but unlike tobacco leaves, liquid nicotine can be seriously threat your health. It can cause harm while inhaling, but it can also be harmful while ingested or absorbed through the skin. Some testing suggests it’s not only the nicotine that could be dangerous. Certain e-cigarette devices produce metals during use, including tin in some cases like other impurities known to be toxic and carcinogenic.
Many regulatory agencies and health professionals can’t estimate how safe e-cigarettes are. The amount of nicotine listed on a cartridge label may not match the real amount in the cartridge. FDA testing has found cartridges under the same manufacturing label may release significantly different amount of nicotine. And for those nicotine-free cartridges, lab tests reveals you’re still getting a low dose, despite the claims.
The FDA regulates several tobacco products, including cigarettes, cigarette tobacco, roll-your-own tobacco and smokeless tobacco. But it wasn’t until 2014 that the agency proposed requirements for e-cigarettes, nicotine gels and dissolvable tobacco. Under these regulations manufacturers have to disclose all ingredients in their products, and have FDA approval before producing them. Moreover, e-cigs can’t be sold to minors, and all labeling must include health warnings; free samples and vending machine sales are also prohibited.
E-cigarette work with a battery, and as long as you keep the battery charged they’re reusable. And like a lot of other devices we use every day many e-cigs come with USB and car charges. It’s not only the rechargeable battery that makes these devices reusable; but also they have the ability of being refilled. The liquid in the cartridges needs to be resupplied regularly, by inserting a new cartridge or refilling the empty cartridge.
Smokers with a pack-a-day habit spend more than $1,000 per year to get the nicotine they need, and in many cases an e-cigarette habit is much cheaper. A typical starter kit, which contains the e-cigarette device, a battery and several cartridges, costs from $30 to $100, depending on the brand, model and style. The cost of a year’s worth of replacement cartridges for keeping the equivalent of a pack-a-day habit will cost $600. To reduce those prices you also can buy the liquid in bulk and refill the cartridges themselves.
Because there’s little regulation of e-cigarette devices, manufacturers claim that their cigarettes can be smoked anywhere, presenting them as smokeless tobacco products that have no health risks. As a result, e-cigs are allowed in otherwise smoke-free environments.
It’s not only smokers who are affected by cigarettes; as many as 2.5 million nonsmokers have died from the lethal effects of secondhand smoke. But e-cigs manufacturers claim that they’re a safe alternative to usual cigarettes, e-cigarettes may not completely solve the problem of secondhand exposure to nicotine.
Cigarette smokers are known to be at higher risk of cancers, the biggest risk being lung cancer; tobacco users are 15 to 30 times more likely to be diagnosed with or die as a result of lung cancer than nonsmokers, and tobacco use causes 90 percent of all lung cancers. Although the marketing claims that e-cigarettes are much safer than smoking tobacco, scientists are finding e-cig users experience diminished lung function, airway resistance and cellular changes, regardless of whether or not they currently smoke cigarettes.
