For many years, doctors and governments have been seeking to wean smokers off their habit. It is a tricky task. Nicotine is as addictive as heroin and cocaine. There are numerous officially approved options for quitting. People can try inhalators, gum, lozenges, patches, nasal sprays and prescription medications. All may help, but few replicate all of the physical and social customs that surround cigarettes. That limits how appealing they may be to committed smokers.
It was into this mix that e-cigarettes arrived in regards to a decade ago. Unlike ordinary cigarettes, which count on burning tobacco to deliver their payload, e-cigarettes use an electric charge to vaporise a dose of nicotine (accompanied, often, by various flavouring chemicals). They have proved extremely popular, especially in America, Britain and Japan. Public-health officials have already been quick to conclude they are a lot better than smoking. Consumers, says Robert West, a professor of health psychology at University College London, are “voting with their lungs”.
Still, not many are happy. E-cigarettes are new, so information about their effects is still scarce. Others concern yourself with who may be utilizing them. The Food and Drug Administration, an American regulator, says it offers data showing an “epidemic” of vaping among teenagers which it can release in the coming months. Earlier this month it put cheap vapor cigarette on notice that they must try to combat underage use of their products and services or face sanction. How worried should vapers-or their parents-be?
The chemistry is the greatest place to begin. Cigarette smoke is genuinely nasty stuff. It includes about 70 carcinogens, in addition to carbon monoxide (a poison), particulates, toxic heavy metals such as cadmium and arsenic, oxidising chemicals and assorted other organic compounds.
The composition of e-cigarette vapour varies between brands. A best guess shows that, instead of the a large number of different compounds in tobacco smoke, it has merely hundreds. Its main ingredients-propylene glycol and glycerol-are considered to be mostly harmless when inhaled. But that is certainly not certain. People who have chronic contact with special-effect fogs used in theatres-that contain propylene glycol-have reported respiratory problems. Nitrosamines, a carcinogenic family of chemicals, have been discovered in electronic cigarette vapour, albeit at levels low enough to get deemed insignificant. Metallic particles from the device’s heating element, such as nickel and cadmium, will also be an issue.
The JUUL is a very unique and innovative electronic cigarette and differs in shape to the other devices in this posting, although it’s roughly the same size as a few of the smallest e-cigs tested! Their intuitive sophisticated Apple-like design results in a very simple and powerful e-cigarette. Some have even been calling it the iPhone of e-cigs.
The JUUL offers the biggest throat hit of all e-cigs we tested, given its high nicotine level and vapor production. The JUUL can be quickly recharged using its magnetic USB charging adapter. The pods hold .7 mL of e-liquid and keep going for a surprisingly very long time. It is possible to see why a lot of experienced vapers select the Juul for their stealth vape while they are out contributing to!
Some studies have found that e-cigarette vapour can contain high amounts of unambiguously nasty chemicals such as formaldehyde, acetaldehyde and acrolein, all based on other substances that have been exposed to high temperatures. The vapour also includes free radicals, highly oxidising substances which could damage tissue or DNA, and that are considered to toastw mostly from flavourings. Based on work published this January flavourings such as cinnamon, vanilla and butter generate by far the most.
Several studies in mice have confirmed that this vapour can induce an inflammatory response within the lungs. In June, for example, Laura Crotty Alexander at the University of California San Diego and her colleagues published results which showed that electronic cigarette vapour has many different unpleasant effects, inducing kidney dysfunction and a thickening and scarring of connective tissue in their hearts called fibrosis. Her data claim that the vapour can also be disrupting the epithelial barrier that lines the lungs, triggering inflammation. They speculate that this could make it easier for pathogens like bacteria to take hold. That will match recent work by Lisa Miyashita at Queen Mary University of London, which discovered that vaping makes cells lining the airways stickier and more prone to bacterial colonisation.
