Researchers have found that vaping causes concerning health problems that take over your body seconds after you puff on an e-cigarette.
Vaping has long been promoted as a less harmful option to smoking tobacco products, but as more and more research is done on the devices that mimic smoking cigarettes, the toxicity of vaping is becoming more and more apparent.
Disposable vapes will be outlawed in the UK in 2025, the government has declared, in an effort to stop youngsters as young as 11 from using them. The price of the liquids used in refillable vapes will more than treble due to a proposed vaping tax.
As smoking grows more common among younger people, Sir Keir Starmer’s government is enacting a first-of-its-kind generational smoking ban as part of a larger campaign to enhance public health.
According to new research released today (November 25) by the Radiological Society of North America (RNSA), both vapes and cigarettes can have acute effects on your “vascular function”—even if you don’t consume any nicotine.
“Compared to tobacco smoke, vapes contain a lot fewer chemicals and carcinogens. Because of this, many people think that e-cigarettes are less dangerous than smoking cigarettes, according to the RNSA.
However, a recent study by Marianne Nabbout, MD, suggests that we should reconsider the effects of vaping on our bodies, as the harm is still present.
Dr. Nabbout, a radiology intern at the University of Arkansas for Medical Sciences in Little Rock, stated that “e-cigarettes have long been marketed as a safer alternative to regular tobacco smoking.”
“Some believe that e-cigarettes don’t contain any of the harmful products, such as free radicals, found in regular tobacco cigarettes, because no combustion is involved.”
In the University of Pennsylvania study, Dr. Nabbout and associates aimed to determine the immediate effects of vaping e-cigarettes with and without nicotine, as well as the acute impacts of smoking cigarettes on vascular function, or the body’s capacity to pump blood through it as necessary.
Thus far, the study has included 31 healthy smokers and vapers with ages ranging from 21 to 49.
Prior to and following each of the following smoking/vaping episodes—tobacco cigarettes, e-cigarette aerosol with nicotine, and e-cigarette aerosol without nicotine—study participants received two MRI scans in three different sessions.
The upper thigh was cuffed to prevent blood flow. Following deflation, venous oxygen saturation—a measurement of the quantity of oxygen in the blood that returns to the heart after delivering oxygen to the body’s tissues—and femoral artery flow velocity—a measurement of the speed of blood flow in the femoral artery—were assessed. Phase-contrast MRI, a specialized form of MRI, was used to quantify cerebrovascular reactivity, or blood flow in the brain.
Ten non-smokers and non-vapers, ages 21 to 33, had their baseline scans compared to the data of the smokers and vapers.
The resting blood flow velocity in the superficial femoral artery significantly decreased after inhaling each form of smoking or vaping. The entire lower body receives oxygenated blood from this artery, which travels along the thigh.
After inhaling nicotine-containing e-cigarettes, the decline in vascular function was most noticeable, followed by those without nicotine. Regardless of whether the e-cigarettes contained nicotine or not, vapers also had decreased venous oxygen saturation. This implies that following vaping, the lungs’ ability to absorb oxygen is immediately reduced.
The public’s lesson, according to Dr. Nabbout, is that vaping might not be risk-free. “In the end, we are depending on science to help direct the regulation of such products in favor of public health,” the speaker stated. Avoiding smoking and vaping is always advised
