A study of saliva samples from a small group of electronic-cigarette users confirmed that vaping produces chemicals capable of damaging DNA and potentially increasing cancer risk.
Do vapers have different DNA changes?
Vapers experience DNA changes, according to a recent paper published in Nature, and the changes are similar to those seen in smokers – although much less pronounced.
Does vaping cause DNA damage?
Dator and Balbo identified three DNA-damaging compounds, formaldehyde, acrolein and methylglyoxal, whose levels increased in the saliva after vaping. Compared with people who don't vape, four of the five e-cigarette users showed increased DNA damage related to acrolein exposure.
Does vaping cause cancer?
Studies that do not examine direct clinical effects are easily interpreted and reported as evidence of health damage. A Daily Mail headline states: “Vaping damages DNA and raises the risk of cancer the same way as cigarettes, study claims”.
Can e-cigarettes damage DNA?
E-cigarettes can damage DNA. "We want to characterize the chemicals that vapers are exposed to, as well as any DNA damage they may cause.". Introduced to the market in 2004, e-cigarettes are handheld electronic devices that heat a liquid, usually containing nicotine, into an aerosol that the user inhales.

How does vaping affect DNA?
How vaping affects the DNA is an important topic. It has the potential to inform estimates of the risk posed by vaping in comparison to smoking, especially as we improve our understanding of the consequences of changes to the DNA.
How long does it take for a smoke test to show a change in DNA?
The results showed that vapour had no effect after three hours of continuous exposure, whereas cigarette smoke did after just 24 minutes.
What is DNA methylation?
DNA methylation is a complicated topic to delve into, but it’s essentially plays a role in gene expression – i.e. how the information from the genes is used by the body to make proteins. Dr. Gage explained:
How long does methylation stay high after quitting smoking?
Although most of the methylation sites returned to levels typical for non-smokers five years after quitting, some changes persisted for a massive 30 years after quitting.
What is the name of the process of adding a CH3 group to DNA?
One such factor is DNA methylation: a form of epigenetics (literally meaning “above” genetics). The technical details of what methylation is involve the addition of a “methyl” (CH3) group to the DNA strand, usually in a specific spot on one of the four main components of DNA, cytosine. Methylation happens throughout the genome, ...
How many genes are linked to smoking?
In line with Dr. Gage’s comments, a 2016 study of almost 16,000 participants found that smoking-related methylation sites were linked to over 7,000 genes, which is around a third of human genes overall. The most robust results they found were linked to genes associated with smoking-related diseases such as cardiovascular disease and some cancers. Although most of the methylation sites returned to levels typical for non-smokers five years after quitting, some changes persisted for a massive 30 years after quitting.
What is the genetic code of every cell?
Everyone has a unique genetic code (or genome) which is made of DNA, is in every cell in your body and provides a “blueprint” of who you are. But other factors influence how your genome is read i.e. how easy it is for proteins to be coded from various parts of DNA. One such factor is DNA methylation: a form of epigenetics ...
How long does vaping take to damage DNA?
They collected saliva samples before and after a 15-minute vaping session and analyzed the samples for chemicals that are known to damage DNA. To evaluate possible long-term effects of vaping, the team assessed DNA damage in the cells of the volunteers' mouths.
What are the three DNA-damaging compounds?
Dator and Balbo identified three DNA-damaging compounds, formaldehyde, acrolein and methylglyoxal, whose levels increased in the saliva after vaping. Compared with people who don't vape, four of the five e-cigarette users showed increased DNA damage related to acrolein exposure. The type of damage, called a DNA adduct, occurs when toxic chemicals, ...
What happens if a cell does not repair DNA damage?
If the cell does not repair the damage so that normal DNA replication can take place, cancer could result. The researchers plan to follow up this preliminary study with a larger one involving more e-cigarette users and controls.
When did e-cigarettes come out?
Introduced to the market in 2004, e-cigarettes are handheld electronic devices that heat a liquid, usually containing nicotine, into an aerosol that the user inhales. Different flavors of liquids are available, including many that appeal to youth, such as fruit, chocolate and candy.
Is vaping bad for you?
But the long-term effects of e-cigarette usage, commonly called 'vaping,' are unknown. Today, researchers report that vaping may modify the genetic material, or DNA, in the oral cells of users, which could increase their cancer risk. The popularity of electronic cigarettes continues to grow worldwide, as many people view them as a safer alternative ...
Can e-cigarettes damage DNA?
E-cigarettes can damage DNA. The popularity of electronic cigarettes continues to grow worldwide, as many people view them as a safer alternative to smoking. But the long-term effects of e-cigarette usage, commonly called 'vaping,' are unknown. Today, researchers report that vaping may modify the genetic material, or DNA, ...
Is vaping a long term effect?
But the long-term effects of e-cigarette usage, commonly called " vaping," are unknown.
Is VaporDNA a rechargeable battery?
There is an inherent risk with the use of any and all rechargeable batteries in any circumstance. VaporDNA® and any and all of VaporDNA®'s parent and subsidiary companies are not responsible for damage if there is any modification of the batteries/chargers in any form or shape (including pack making).
Is VaporDNA a Li-ion?
VaporDNA® and any and all of VaporDNA®'s parent and subsidiary companies are not responsible for any damage caused by the misuse and/or mishandling of Li-ion (Lithium-ion), LiPo (Lithium-ion Polymer) and any rechargeable batteries and chargers.
