While some research has reported that they are considerably safer than tobacco cigarettes, a new study from researchers at the University of Connecticut claims something different: that vaping using a device filled with nicotine-based liquid can cause just as much DNA damage as smoking regular cigarettes.
Why are vapes bad for your health?
One of the reasons why vapes are bad for your health is that they can damage your DNA. A 2018 report by the American Chemical Society found that vaping e-cigarettes can affect the DNA structure of cells in your mouth. The irritating effect of inhaling and exhaling flavored vapors could increase your risk of cancer.
Does vaping cause cancer like smoking?
A Daily Mail headline states: “Vaping damages DNA and raises the risk of cancer the same way as cigarettes”. Although the second part of the headline offers balance: “but it’s not as bad as traditional smoking”, the damage to public perceptions may already be done. No one is claiming that e-cigarettes are completely risk free.
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.
Can vaping cause a stroke?
Vaping doesn’t just do damage to your lungs but can also cause cognitive impairment that causes a stroke. Vaping chemical-laden juices has the effect of causing inflammation damage in your brain. Some studies have shown that vaping can result in vascular inflammatory responses that can be a factor in suffering a stroke.
Does vaping cause DNA damage?
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.
How long does vape stay in your DNA?
One study from late 2016 (from British American Tobacco) used the Ames test (which tests for DNA mutations using bacteria) to compare smoke to vapour from e-cigarettes. The results showed that vapour had no effect after three hours of continuous exposure, whereas cigarette smoke did after just 24 minutes.
Does nicotine cause DNA damage?
Nicotine Induces DNA Damage in Human Cells. Many tobacco-specific nitrosamines that result from the nitrosation of nicotine, such as NNN and NNK, are potent carcinogens and can induce cancer in different organs, including the lung (20, 21, 27).
How does smoking affect your DNA?
The habit can add chemical modifications to genes involved in cancer. Cigarettes leave you with more than a smoky scent on your clothes and fingernails. A new study has found strong evidence that tobacco use can chemically modify and affect the activity of genes known to increase the risk of developing cancer.
How long is vaping detected in your blood?
Vape in the System: Blood Vape stays in the blood for around a day or three (3) days in the case of nicotine and up to ten (10) days in the case of cotinine.
How long does 1 hit of nicotine stay in system?
Nicotine is typically only detectable in your bloodstream for a short amount of time (about one to three days), whereas its metabolites last in the body longer: up to ten days. In fact, after your final exposure to nicotine, about half of it is already broken down by the body within a matter of hours.
Does nicotine affect sperm DNA?
The harmful substances in tobacco inhaled by smokers cause DNA damage, which may elevate DNA fragmentation rates (15,16). Increased sperm DNA fragmentation rates have been positively correlated with impaired fertility (17).
Does smoking mutate DNA?
Smoking leaves an "archaeological record" of the hundreds of DNA mutations it causes, scientists have discovered. Having sequenced thousands of tumour genomes, they found a 20-a-day smoker would rack up an average of 150 mutations in every lung cell each year.
Does vaping effect your health?
2: Research suggests vaping is bad for your heart and lungs. It causes you to crave a smoke and suffer withdrawal symptoms if you ignore the craving. Nicotine is a toxic substance. It raises your blood pressure and spikes your adrenaline, which increases your heart rate and the likelihood of having a heart attack.
Can you damage your DNA?
DNA can be damaged via environmental factors as well. Environmental agents such as UV light, ionizing radiation, and genotoxic chemicals. Replication forks can be stalled due to damaged DNA and double strand breaks are also a form of DNA damage.
Does nicotine stay in your body forever?
Generally, nicotine will leaves your blood within 1 to 3 days after you stop using tobacco, and cotinine will be gone after 1 to 10 days. Neither nicotine nor cotinine will be detectable in your urine after 3 to 4 days of stopping tobacco products.
How does smoking alter genes?
Cigarette smoking activates oxidative and inflammatory response and leads to uncontrolled structural changes in airways and alters gene expression. Such changes have a characteristic similar to that for COPD patients. Therefore, smoking is determined as a key risk factor for chronic respiratory disease development.
Can doctors tell if you smoke from a blood test?
Nicotine shows up in blood tests, as do its metabolites, including cotinine and anabasine . Nicotine itself may be present in the blood for only 48 hours, while cotinine may be detectable for up to three weeks. After blood is drawn in a lab, results can take from two to 10 days.
What does DNA mean in vaping?
If you're looking to get the best performance out of your vape, look no further than a DNA mod. A DNA mod is any mod that uses Evolv's DNA chip to regulate and deliver power. Especially revered among temperature control vapers, DNA chips have proven to be the most accurate and reliable chips currently available.
Does vaping affect blood tests?
Smoking can also affect blood test results. If a person has been asked to fast before a blood test, they should avoid smoking. If you vape, it's fine to continue doing this during your fast.
Do drug tests test for nicotine?
Nicotine and cotinine testing detect evidence of nicotine use and presumed tobacco usage. Testing is most often performed on a sample of urine or saliva, but may also be performed on samples of blood or hair.
Not a safer alternative to smoking?
Since hitting the market over a decade ago, e-cigarettes have become particularly popular among young people. They come in a variety of flavors and companies often market them as a safe alternative to tobacco products. However, many studies have suggested otherwise.
Vaping likely another source of cancer
The researchers have previously shown e-cigarette users develop some of the same cancer-related molecular changes in oral tissue as smokers. They also discovered vapers had the same kind of cancer-linked chemical changes to their genome.
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 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.
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.

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.
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.
Does vaping damage you?
While there will always be uncertainty surrounding how much you can conclude from short-term changes, any direct comparisons between smoking and vaping have consistently shown that vaping does much less damage.
Does smoking cause DNA damage?
One possibility is direct damage to the DNA as a result of the cancer-causing chemicals in smoke, with the repair process leading to methylation of the nearby sections of the DNA, and another possibility is that nicotine itself affects gene expression, which may have impacts on methylation.
