Is vaping better than smoking cigarettes?

Thomas Munzel and co-authors report from Mainz on the advantages and disadvantages of electronic cigarette smoking

In the current era of the coronavirus pandemic, there is unusual to discuss another health issue, such as smoking cigarettes, or the best way to stop smoking cigarettes, like the use of e-cigarettes. However, smoking cigarettes and especially chronic obstructive lung disease is an indicator of risk for the development of severe COVID-19-related infection. In addition, The Global Burden of Disease Study ranks smoking cigarettes as the second most dangerous factor that cause deaths across the globe and is the second most dangerous after hypertension. 1

The electronic (e)-cigarette Disposable vape is a source of considerably fewer toxins than cigarettes, has been advertised as a healthy alternative to smoking traditional cigarettes and is believed to be a reliable method for quitting smoking. 2 As the result it has seen an increase in electronic cigarettes, especially for young people, with the result that e-cigarettes quickly became the most frequently used cigarettes within the USA. 3

The rapid growth in e-cigarette sales has raised concerns over the negative health effects on high school and middle school students. 4 This issue is further confirmed due to the recent launch of vaping devices with high nicotine content like ‘JUUL’, with no full understanding of the health risks of long-term e-cigarette use.

Vaping e-cigarettes is as risky as smoking tobacco?

No, definitely certainly not.

Many researchers agree on the serious health risks arising from the reports of the Center for Disease Control (CDC) and the Food and Drug Administration (FDA) and State Health Departments relating to severe lung disease and deaths in e-cigarette users is likely to be due to the presence of vitamin E acetate, particularly in the form of tetrahydrocannabinol found in e as well as vaping items.

Do we think switching from smoking tobacco to electronic cigarettes good to our boats?

Definitely.

There are a number of studies that show an improvement in the function of the endothelial cells as a result of switching from smoking tobacco to electronic cigarettes. For instance, within one month after switching from smoking tobacco to e-cigarette vaping , there was a noticeable increase in endothelial function as well as the stiffness of the vascular system ( Figure 1). 5 Females had more benefit by switching than males in every comparison between groups. People who did the best at switching to e-cigarettes showed the most significant increase.

What data are we lacking in relation to E-cigarettes?

There is a significant lack of information regarding the health implications for the entire population of using electronic cigarettes. According to the study, a majority of studies available provide evidence that e-cigarettes are not as harmful as smoking tobacco, 6.7 However, both the number of long-term studies, as well as the number of mechanistic studies, aren’t as extensive. If one considers that vaping is linked to lower typical age for first-time (e)-cigarette users, then the healthier electronic cigarettes profile could easily be scuttled (or perhaps reversed) due to the greater percentage of adolescents who use. It is therefore possible that vaping e-cigarettes could negatively affect the general population’s disability-adjusted life span, resulting in an increased burden of disease.

What is the mechanism behind the cardiovascular, pulmonary, and cerebral side effects of electronic cigarettes?

The rapid vaping of a single e-cigarette raises heart rate and causes the arteries to stiffen and cause malfunction of the lining of arteries for healthy smokers. 8 It is vital to remember that the endothelium controls the proper constriction and dilation of blood vessels, shields tissues from harmful substances, and also regulates inflammation and blood process clotting. Endothelial dysfunction can be a factor in the development of cardiovascular diseases and, consequently, is a pre-eminent indicator of the risk of developing cardiovascular disease.

The results of animal studies show that vaping with e-cigarettes results in hypertension, inflammation of the brain, lungs and vessels due an increase in inflammation as well as an increase in oxidative stress. This is likely caused by major toxicants found in emissions like acrolein formaldehyde, as well as Acetaldehyde. The elimination of the phagocytic NADPH Oxase (subtype NOX-2) significantly protects animals from cerebral and vascular adverse effects of vaping, like the endothelin-receptor antagonist Macitentan. 8

A recent examination of published studies revealed little evidence that suggests that e-cigarette consumption may result in less adverse cardiovascular effects than traditional smoking cigarettes. 9 The studies in the review revealed that e-cigarettes may cause adverse cardiovascular effects in a variety of ways, such as inflammation, oxidative stress arterial stiffness, DNA damage, and altered hemodynamics and platelet function, both separately or in combination together. These results suggest pathways that e-cigarettes used for a long time could contribute to the development of cardiovascular diseases. Therefore, further quality controlled studies that are randomized and of high quality are required to determine conclusively the safety and effectiveness of electronic cigarettes..

What are the guidelines from the regulatory authorities?

In the USA In the United States, the FDA regulates every aspect of sales and production. In 2016 the FDA added e-cigarettes to the tobacco product list and therefore they are regulated in the same manner as cigarettes made from tobacco. While the FDA permits sales of e-cigarettes but some organizations in the USA have demanded their complete ban. The CDC advises that e-cigarettes of any kind should not be used by children 10 and that vapers should stay away from the habit completely. 11

The World Health Organization (WHO) expressed doubts about the benefits of electronic cigarettes and expressed grave fears about the risks they pose. 12 The American Heart Association (AHA) has begun an initiative to stop all sales of e-cigarettes. 13 The AHA is also claiming that there is sufficient evidence to link e-cigarettes with teens’ addiction to nicotine as well as the increase in the number of smokers who are attracted to smoking.

The position of Europe regarding e-cigarettes isn’t uniform in any way. In the UK there are two main groups: the National Health Service (NHS) as well as the British Heart Foundation (BHF) have a strong stance in support of electronic cigarettes in order to reduce the use of tobacco. According to a YouGov study, 14 more than 3.6 million adults ~7.1 percent of the population of adults in the UK utilize electronic cigarettes. Of these 54% of them are former smokers and are attempting to quit smoking. It is believed that it may become easier to give up smoking using the use of an electronic cigarette. They also suggest anyone who smokes with a heart problem ought to consider e-cigarettes, especially if they have tried to quit in the past but were unsuccessful. They suggest that it could be much more simple to quit smoking an electronic device, but they’re likely not secure. While they’re less harmful the proposed 90% less dangerous claim by Public Health England and the Royal College of Physicians for E-cigarettes needs to be reviewed quickly because of the increasing amount of evidence about possible health-related side effects caused by electronic cigarettes.

A formal suggestion from the European Society of Cardiology on how to handle the issue of e-cigarettes is certainly something that should be welcomed.

In general, the alarmingly increase in the use of electronic cigarettes is alarming and wider tobacco control measures such as raising taxes on tobacco, implementing smoking-free laws, conducting massive media campaigns, and limiting the marketing of tobacco should be taken into consideration to improve the health of the population in general. 15

Future research should be focused on the long-term negative effects of vaping with e-cigarettes for the cardiovascular system as well as cancer of the respiratory system because evidence of their effects is not yet available. Vapour that is secondhand are the most likely to benefit from more information about the effects on cardiovascular diseases resulting from vaping e-cigarettes.

While we’re aware that e-cigarettes are safer in comparison to tobacco, we’re conscious of their potential to create nicotine addicts which could be enough to cause more stringent regulations for these products. It is undisputed that quitting smoking remains the most effective strategy to avoid the onset of respiratory and cardiovascular disease.
