It all sounds stressing. But a dose of scepticism is helpful too. One alarming study in August said that e-cigarette users are more likely to have been clinically determined to have heart disease. But some vapers have smoked before, or still do. The paper might have been picking up old harms from smoking, instead of new ones from vaping. Many think that the toxic nature of fake cigarettes water vapor may have been exaggerated by unrealistic laboratory conditions. Overheating the fluid creates an upsetting taste that users actively avoid. Lab tests may heat the fluid more strongly than real vapers do, for example.
The last piece of the puzzle will be the nicotine. Besides being addictive, it may come with an adverse affect all over the body. However the current source of issue is its effects on children. As an example, work in animals implies that exposure to nicotine may be bad for adolescent brains, making users more susceptible to other addictive substances down the road. This could be one reason why human smokers who start young have higher rates of addiction as adults. It could also suggest that children who vape risk an ongoing dependence on nicotine, and may even start smoking. But, says Dr West, these concerns have not been borne out by epidemiological studies.
Smoking during adolescence has also been related to lasting cognitive and behavioural impairments, including on working memory and attention. Animal tests advise that contact with nicotine specifically could explain xjelej least some of that effect. All this forms the scientific backdrop towards the FDA’s worries concerning the effects of vaping among the young.
Getting definitive answers will take time. Epidemiology is really a tricky business. A variety of confounding factors and overlooked connections can skew conclusions. Smoking stands out in medical history being a pastime which is so unambiguously bad for you the signal cuts through almost any amount of noise. The real truth about e-cigarettes will take longer to tease out.
That could sound frustratingly vague. However it points to at least one clear conclusion-whether it is harmless or only moderately harmful to you, vaping is practically certainly safer than smoking. Which is a message which needs spreading. In Britain regarding a third of smokers say they have not tried vaping because they are concerned about its safety and addictiveness. This attachment to some known evil is self-defeating. At least right now, the electronic cigarette seems like a good innovation in public health.
