Vapeboss – An MRI-based functional study conducted in Switzerland and published in Radiology found that cigarette smoke inhibits lung perfusion, while nicotine e-cigarettes actually increase blood flow in the lungs.
MRI (Magnetic Resonance Imaging) is an examination of body organs performed using magnetic technology and radio waves. This examination is conducted to obtain detailed and in-depth images of organs, bones, and tissues inside the body.
The study, titled "MRI Shows Lung Perfusion Changes after Vaping and Smoking," was conducted by a research team from Bern University Hospital. The study involved 44 healthy adults consisting of 13 vapers, 12 smokers, 9 ex-smokers, and 10 non-users who were then sent for MRI tests and functional lung tests.
The test results showed that current and former tobacco users experienced a significant decrease in lung perfusion/blood flow after smoking. Interestingly, vapers actually experienced an increase in lung perfusion after vaping.
"MRI showed decreased lung perfusion after exposure to tobacco smoke and increased lung perfusion after the use of electronic nicotine delivery systems," the study concluded.
Meanwhile, another recent study conducted by the American Cancer Society highlighted that although quitting smoking reduces cancer risk at any age, doing so before the age of 45 almost eliminates all risk.
Titled "Association of Smoking Initiation and Cessation Across the Life Course and Cancer Mortality Prospective Study of 410,000 US Adults," the study of over 400,000 Americans found that smokers were three times more likely to die from tobacco-related cancer than non-smokers.
However, researchers reported that quitting at age 45 would reduce this risk by 89%, while for those who quit before age 35, the risk was completely eliminated. On the other hand, quitting smoking between ages 45-54 still significantly reduced the risk by 78%, while quitting smoking between ages 55-64 reduced the risk by 56%.
The research team found that the age of smoking initiation also impacted cancer risk. People who started smoking before age 18 had at least three times the risk of cancer mortality, while those who started smoking before age 10 had a four-fold risk.
