Vaping damages DNA and raises risk of cancer the same way as cigarettes, study claims – but it’s not as bad as traditional smoking

Vaping damages people’s DNA in the same way as smoking a normal cigarette — but to a lesser extent — a study warned today.

According to a University of Southern California study, these biological changes can lead to diseases like cancer.


Vaping has been seen as a safer alternative to smoking, with plans to prescribe e-cigarettes to cigarette users in the UK to help them quit.

There have been many studies that suggest that e-cigarettes are harmful, but many questioned whether smoking is still to blame as most vapers also smoke traditional cigarettes or have a prior history of smoking.

But a team of researchers from the University of Southern California found that these biological changes also occur in the vapors of people who have never touched a cigarette.

However, the changes are more widespread among people who smoke tobacco products, the scientists said.

The laws allowing manufacturers to apply vapes are stricter in the UK than in the US, so the US study may not fully reflect the effects of available e-cigarettes on the British market.

The study looked at 82 healthy adults who divided them into three categories – current vapers, those who smoked only cigarettes and a control group who had never smoked or vaped.

They then analyzed the genes of all the participants and looked for changes in gene regulation in each participant’s blood cells.

When the normal regulation of a gene is disrupted it can interfere with the function of the gene, leading to disease.

The research studied 37 current vapers, 22 current smokers and 23 non-smokers in Los Angeles. Vapers currently smoking were excluded from the results.

They took blood samples from the participants to determine how many contaminating genes were in the different groups.

After accounting for age and sex, they found a ‘statistically significant’ association of damaged genes in vaping – even if they had never smoked.

Lead author and Professor of Research Population and Public Health Sciences Dr Ahmed Besartinia said: ‘Our study, for the first time, examines the biological effects of vaping in adult e-cigarette users, as well as accounting for their past smoking exposure. does.

‘Our data indicate that smoking, like smoking, is associated with the regulation of mitochondrial genes and the disruption of molecular pathways involved in immunity and the inflammatory response, which govern health versus disease status.’

E-cigarette users 15% more likely to have a stroke in middle age than regular smokers, study claims

Research suggests that e-cigarette users may be more likely to have a stroke in middle age than traditional smokers.

Academics in New York – who tracked nearly 80,000 Americans – found that smokers were six times more likely to have a stroke than vapers.

But vapors faced a nearly 15 percent higher risk at an earlier age than smokers.

E-cigarette users had their first stroke at an average age of 48 — a decade earlier than traditional cigarette smokers.

While vaping is generally considered to be healthier than cigarettes, researchers caution that exposure to the devices at a young age can still cause irreparable harm.

Cigarette smoking increases the risk of stroke as well as suffering from other conditions including cancer and heart disease.


The study found that 12 percent of the affected genes in the vapor were in mitochondria – parts of cells that scientists say can help the immune system work effectively and prevent cancer and other diseases from developing .

The number of damaged genes in smokers was about 7.4 times higher than in vapers, the researchers said.

Mitochondria – the ‘engine’ of cells that produce energy They also play an important role in regulating the body’s immune system.

When mitochondria are damaged, the body is more prone to heart disease and cancer.

Dr Basartinia said: ‘When mitochondria become inactive, they release key molecules.

‘The molecules released can act as signals to the immune system, triggering an immune response that leads to inflammation, which is important not only for maintaining health but also for cardiovascular and respiratory diseases. Like it also plays an important role in the development of various diseases. Metabolic diseases, and cancer.’

It was announced last month that England is set to become the first country in the world to prescribe e-cigarettes to help smokers quit.

Despite a torrent of evidence on the health risks of vaping, the medical regulator has to ‘pave the way’ on introducing it to the NHS.

Manufacturers will be able to submit e-cigarettes to the drugs and health products regulatory agency to go through the same ‘approval process’ like other drugs.

This means they can then be licensed as a medical product and prescribed by doctors on a case-by-case basis to people who want to give up traditional cigarettes.

Currently, the NHS advises that vaping can help smokers – although this is not available on prescription.

E-cigarette devices usually cost around £20 to £30, plus more for replacement cartridges.

The controversial move comes despite the World Health Organization saying last year that the devices are “undoubtedly harmful”.

Some 3 million Britons currently use vapes, which is more than three times as many as 700,000 a decade ago.

For comparison, there are currently 7 million smokers in the UK, more than half of what it was a decade ago.

The researchers said the results may have been affected by a higher number of smokers than by vaping — 37 and 22, respectively.

But he said…
