Is Vaping Safer than Smoking Cigarettes?

Electronic cigarettes, or e-cigarettes,
are being marketed as the “safe” new alternative to conventional cigarettes. They now come in a variety of forms and include vape mods, Juuls, and vape pens. The focus of this article is on e-cigarettes because most of the research that exists has been done on them, but much of the information below is relevant to these other products as well.
The big questions are: Are they safe? What does the FDA think about them? Will they reverse the decline in smoking—giving new life to an old habit—or can they help people quit smoking? Here is what you need to know.
What are E-cigarettes?
E-cigarettes are battery-operated devices that were initially shaped like cigarettes, but now include vape mods, Juuls, and vape pens. All these products contain nicotine, an addictive drug that stimulates, relaxes, and is naturally found in tobacco. It is the nicotine in cigarettes that makes smoking so addictive, and the same is true for vaping and juuling. These electronic products allow nicotine to be inhaled, and they work by heating a liquid cartridge containing nicotine, flavors, and other chemicals into a vapor. Because e-cigarettes heat a liquid instead of tobacco, what is released is considered smokeless.[1]
Is Vaping Safer than Smoking Traditional Cigarettes?
The key difference between traditional cigarettes and e-cigarettes and related products is that the latter don’t contain tobacco. But, it isn’t just the tobacco in cigarettes that causes cancer. Traditional cigarettes contain a laundry list of chemicals that are proven harmful, and e-cigarettes have some of these same chemicals.
Since 2009, FDA has pointed out that e-cigarettes contain “detectable levels of known carcinogens and toxic chemicals to which users could be exposed.” For example, in e-cigarette cartridges marketed as “tobacco-free,” the FDA detected a toxic compound found in antifreeze, tobacco-specific compounds that have been shown to cause cancer in humans, and other toxic tobacco-specific impurities.[2] Another study looked at 42 of these liquid cartridges and determined that they contained formaldehyde, a chemical known to cause cancer in humans.[3] Formaldehyde was found in several of the cartridges at levels much higher than the maximum EPA recommends for humans. In 2017, a study published in the Public Library of Science Journal showed that significant levels of benzene, a well-known carcinogen, were found in the vapor produced by several popular brands of e-cigarettes. [4]
The body’s reaction to many of the chemicals in traditional cigarette smoke causes long-lasting inflammation, which in turn leads to chronic diseases like bronchitis, emphysema, and heart disease.[5] Since e-cigarettes also contain many of the same toxic chemicals, there is no reason to believe that they will significantly reduce the risks for these diseases.
In fact, a preliminary study presented at the 2018 annual meeting of the American Chemical Society found that vaping could damage DNA [16]. The study examined the saliva of 5 adults before and after a 15-minute vaping session. The saliva had an increase in potentially dangerous chemicals, such as formaldehyde and acrolein. Acrolein has been proven to be associated with DNA damage, for example, and DNA damage can eventually cause cancer. [18]
A study of mice funded by the National Institutes of Health found that e-cigarette smoke could cause mutations in DNA that could increase the risk of cancer. These specific mutations have been shown to potentially contribute to the development of lung and bladder cancer in mice exposed to electronic cigarette smoke. The researchers claim that these chemicals could also induce mutations leading to cancer in humans. Although mice studies aren’t always relevant to human health, this study seems to confirm the studies of human health and e-cigarettes. [19]
Because they are smokeless, many incorrectly assume that e-cigarettes are safer for non-smokers and the environment than traditional cigarettes. However, a study published in the International Journal of Hygiene and Environmental Health found that the use of e-cigarettes results in increased concentrations of volatile organic compounds (VOCs) and airborne particles, both of which are potentially harmful when inhaled.[6] Although e-cigarette vapor may not result in the obvious smell and visible smoke of traditional cigarettes, it still has a negative impact on air quality, especially when vaping indoors.
There are no long-term studies to back up claims that the vapor from e-cigarettes is less harmful than conventional smoke. Cancer takes years to develop, and e-cigarettes were only very recently introduced to the United States. It is almost impossible to determine if a product increases a person’s risk of cancer or not until the product has been around for at least 15-20 years. Despite positive reviews from e-cigarette users who enjoy being able to smoke them where regular cigarettes are prohibited, very little is known about their safety and long-term health effects.
There is also danger from e-cigarettes exploding in the user’s mouth or face. Last year, the British Medical Journal used data from several agencies to estimate that there were roughly 2,035 e-cigarette explosion and burn injuries in the U.S. just in a three-year period from 2015 to 2017. One of the authors of the study stated that the number was likely higher as such incidents were not well tracked. The report also said that e-cigarettes, commonly powered by a lithium-ion battery, could overheat to the point of catching fire or exploding, a phenomenon known as “thermal runway”.[20]
Be a fukking idiot with no common sense brahs
E cigarettes
Dont have the 1 actually natural substance "tobacco"
Which is the less harmful part of real cigarettes
U have wayyy
Less health risk if you rolled your own
Home grown tobbaco cigarettes
Think that inhaling heated chemicals won't kill u
