It all sounds stressing. But a dose of concern is useful too. One alarming study in August claimed that e-cigarette users are more likely to have been diagnosed with heart problems. However, many vapers have smoked previously, or still do. The paper may have been picking up old harms from smoking, rather than new ones from vaping. Many feel that the toxic nature of flavored vapor cigarettes might have been exaggerated by unrealistic laboratory conditions. Overheating the fluid creates an unpleasant taste that users actively avoid. Lab tests may heat the fluid more vigorously than real vapers do, for instance.
The last piece of the puzzle is definitely the nicotine. Besides being addictive, it has proven to come with an adverse affect around the body. Nevertheless the current source of issue is its effects on children. For example, operate in animals suggests that exposure to nicotine might be unhealthy for adolescent brains, making users more prone to other addictive substances in the future. This may be one reasons why human smokers who start young have higher rates of addiction as adults. It may also mean that children who vape risk a lifelong addiction to nicotine, and may also start smoking. But, says Dr West, these concerns have not yet been borne out by epidemiological studies.
Smoking during adolescence has also been connected with lasting cognitive and behavioural impairments, including on working memory and attention. Animal tests suggest that exposure to nicotine specifically could explain xjelej least a number of that effect. This forms the scientific backdrop to the FDA’s worries about the results of vaping among the young.
Getting definitive answers will require time. Epidemiology is really a tricky business. All kinds of confounding factors and overlooked connections can skew conclusions. Smoking stands apart in medical history as a pastime that is so unambiguously bad for you the signal cuts through almost any level of noise. The reality regarding e-cigarettes will require longer to tease out.
Which could sound frustratingly vague. However it points to at least one clear conclusion-be it harmless or only moderately harmful to you, vaping is almost certainly safer than smoking. That is a message which needs spreading. In The Uk about a third of smokers say they have not tried vaping since they are worried about its safety and addictiveness. This attachment to a known evil is self-defeating. At the very least for the time being, the e-cigarette looks like a good innovation in public health.
