For many years, doctors and governments have already been seeking to wean smokers from their habit. It is a tricky task. Nicotine is as addictive as heroin and cocaine. There are plenty of officially endorsed options for quitting. People can try inhalators, gum, lozenges, patches, nasal sprays and prescription medications. All may help, but few replicate all the physical and social rituals that surround cigarettes. That limits how appealing they may be to committed smokers.
It was into this mix that e-cigarettes arrived about a decade ago. Unlike ordinary cigarettes, which rely on burning tobacco to offer 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, particularly 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 making use of their lungs”.
Still, few are happy. E-cigarettes are new, so details about their effects continues to be scarce. Others be worried about who may be using them. The Food and Drug Administration, an American regulator, says it offers data showing an “epidemic” of vaping among teenagers which it can release within the coming months. Earlier this month it put smoking vapor electronic cigarette on notice that they have to attempt to combat underage use of their goods or face sanction. How worried should vapers-or their parents-be?
The chemistry is the best starting point. Tobacco smoke is genuinely nasty stuff. It has about 70 carcinogens, along with deadly carbon monoxide (a poison), particulates, toxic chemical toxins such as cadmium and arsenic, oxidising chemicals and assorted other organic compounds.
The composition of electronic cigarette vapour varies between brands. A best guess implies that, instead of the a large number of different compounds in cigarette smoke, it has merely hundreds. Its primary ingredients-propylene glycol and glycerol-are considered to be mostly harmless when inhaled. But which is not certain. Individuals with chronic being exposed to special-effect fogs used in theatres-which contain propylene glycol-have reported respiratory problems. Nitrosamines, a carcinogenic family of chemicals, have been found in e-cigarette vapour, albeit at levels low enough to be deemed insignificant. Metallic particles through the device’s heating element, like nickel and cadmium, will also be an issue.
The JUUL is definitely a unique and innovative e-cigarette and differs in good shape to the other devices in this posting, although it’s roughly exactly the same size as some of the smallest e-cigs tested! Their intuitive sophisticated Apple-like design results in a very easy and powerful electronic cigarette. Some have even been calling it the iPhone of e-cigs.
The JUUL provides the biggest throat hit of all of the e-cigs we tested, given its high nicotine level and vapor production. The JUUL may also be quickly recharged using its magnetic USB charging adapter. The pods hold .7 mL of e-liquid and serve you for a surprisingly long time. It is possible to see why lots of experienced vapers choose the Juul for his or her stealth vape if they are out contributing to!
Some reports have discovered that e-cigarette vapour can contain high levels of unambiguously nasty chemicals including formaldehyde, acetaldehyde and acrolein, all derived from other ingredients that have been exposed to high temperatures. The vapour also contains free-radicals, highly oxidising substances which can damage tissue or DNA, and that are considered to toastw mostly from flavourings. Based on work published this January flavourings like cinnamon, vanilla and butter generate probably the most.
Several studies in mice have confirmed that this vapour can induce an inflammatory response within the lungs. In June, as an example, Laura Crotty Alexander on the University of California San Diego County and her colleagues published results which demonstrated that e-cigarette vapour has a variety of unpleasant effects, inducing kidney dysfunction and a thickening and scarring of connective tissue within their hearts called fibrosis. Her data suggest that the vapour may also be disrupting the epithelial barrier that lines the lungs, triggering inflammation. They speculate that this could make it simpler for pathogens like bacteria to adopt hold. That could fit with recent work by Lisa Miyashita at Queen Mary University of London, which found that vaping makes cells lining the airways stickier and more susceptible to bacterial colonisation.
