Experts warn vaping after quitting smoking maintains high lung cancer risk |


Medical experts have warned that taking up vaping or continuing to do so after quitting smoking keeps the risk of developing lung cancer ‘high’. The recent surge in vape popularity means there are still uncertainties and potential issues that may arise in years to come associated with this controversial trend.

While some studies suggest health benefits to swapping out smoking cigarettes for a vape, there are potentially serious health issues too. According to medicalnewstoday.com, 15 puffs on an e-cigarette is equivalent to smoking a single cigarette.




Swapping a cigarette for a vape could reduce a person’s exposure to highly toxic cigarette smoke, which may help the body to start healing. However, some chemicals in vapes have been linked to lung damage and disease, particularly cancer. This is most worrying for people who may have already done damage with cigarette smoking.

This warning comes weeks after it was reported that long-term vaping makes cancer “almost a certainty”, according to a study from The Royal College of Surgeons in Ireland. Flavoured vapes mimicking fruit, candy and dessert flavours are the most concerning, Professor of Chemistry at RCSI and lead author of the study Dr Dónal O’Shea said.

These flavours are more dangerous and need “urgent attention” as they contain from six to 20 different chemicals to make the commercial flavour. The study, conducted using artificial intelligence, found that once these chemicals were heated very toxic compounds were detected.

Fruit and candy-flavoured vapes had the most volatile carbonyls (VCs) present, which are known to pose serious health risks such as cancer and pulmonary disease. The study noted that the “cocktail of chemicals” used in these flavours were never intended to be heated to high temperatures for inhalation.

A total of 127 hazardous chemicals detected from vapes used in the study were classified as ‘Acute Toxic’, 153 as ‘Health Hazards’ and 225 as ‘Irritants’. While vape manufacturers say their products are targeted at people trying to quit smoking cigarettes, Professor O’Shea says vaping causes a “different profile of chemical hazards” compared to tobacco.

He said: “We wanted to understand, before it’s too late, the likely impact flavoured vapes are having on the health of the growing number of vapers. It is plausible that we are on the cusp of a new wave of chronic diseases that will emerge 15 to 20 years from now due to these exposures.

“We hope this research will help people make more informed choices and contribute to the conversation on the potential long-term health risks and the regulation of vaping, which this research suggests should be comprehensive.”
