FOR decades, doctors and governments have already been attempting to wean smokers off their habit. It is a tricky task. Nicotine is just as addictive as heroin and cocaine. There are plenty of officially endorsed methods for quitting. People can try inhalators, gum, lozenges, patches, nasal sprays and prescription medications. All will help, but few replicate all the physical and social rituals that surround cigarettes. That limits how desirable they may be to committed smokers.
It had been into this mix that e-cigarettes arrived regarding a decade ago. Unlike ordinary cigarettes, which count on burning tobacco to offer their payload, e-cigarettes work with an electric charge to vaporise a dose of nicotine (accompanied, often, by various flavouring chemicals). They may have proved very popular, particularly in America, Britain and Japan. Public-health officials have already been quick to conclude that 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 information regarding their effects remains 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 is going to release in the coming months. Earlier this month it put free vapor cigarettes on notice that they must try to combat underage usage of their products or face sanction. How worried should vapers-or their parents-be?
The chemistry is the greatest starting point. Cigarette smoke is genuinely nasty stuff. It has about 70 carcinogens, as well as deadly 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 suggests that, rather than the a large number of different compounds in cigarette smoke, it contains merely hundreds. Its main ingredients-propylene glycol and glycerol-are considered to be mostly harmless when inhaled. But that is not certain. People with chronic contact with special-effect fogs used in theatres-that have 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 become deemed insignificant. Metallic particles from the device’s heating element, like nickel and cadmium, are also a concern.
The JUUL is definitely a unique and innovative e-cigarette and differs in good shape towards the other devices in this article, although it’s roughly exactly 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 electronic cigarette. Some have even been calling it the iPhone of e-cigs.
The JUUL offers the biggest throat hit of all of the 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 last a surprisingly very long time. It is possible to understand why a lot of experienced vapers select the Juul for his or her stealth vape when they are out contributing to!
Some research has learned that e-cigarette vapour can contain high amounts of unambiguously nasty chemicals including formaldehyde, acetaldehyde and acrolein, all based on other ingredients that have been exposed to high temperatures. The vapour also includes free radicals, highly oxidising substances which can damage tissue or DNA, and which are thought to toastw mostly from flavourings. Based on work published this January flavourings like cinnamon, vanilla and butter generate by far the most.
Several studies in mice have confirmed that the vapour can induce an inflammatory response within the lungs. In June, for example, Laura Crotty Alexander in the University of California San Diego County and her colleagues published results which indicated that electronic cigarette vapour has a number of unpleasant effects, inducing kidney dysfunction as well as a thickening and scarring of connective tissue in 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 the could make it easier for pathogens like bacteria to take hold. That will 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.
