After just one puff, researchers at the University of Pennsylvania found an immediate change in the body's blood vessels and circulation, ...
How does vaping affect blood flow?
That meant that blood wasn’t flowing as quickly as it was prior to inhaling the vapor. The researchers also found that vaping reduced the amount of oxygen in the blood by 20 percent, and made the walls of the blood vessels more rigid and stiff—a symptom often associated with cardiovascular diseases like hypertension and stroke. Other studies have found similar results in animals, but this is the first such finding in human subjects. “It’s really stunning,” says Sven Jordt, who studies e-cigarettes at Duke University and who was not involved in this study.

Inhaling e-cigarette vapor alone had an immediate, negative impact on the vascular systems of first-time vapers.
What is the effect of smoking on the blood vessels?
April 17, 2020. Answer: Nicotine and surgery. Smoking combines the effect of nicotine that constricts the blood vessels and the effect of carbon monoxide that reduces the ability of the blood to transport oxygen to the tissues.
What does it mean when your blood vessels are narrowed?
Narrowing of the blood vessels means less blood flow and oxygen to the tissues, which you need to heal. This can lead to disastrous complications such as skin loss and wound healing problems, especially in the face.
Does nicotine cause vasoconstriction?
Hello, The answer is "YES"! Nicotine is a vasoconstrictor, meaning it will narrow the arteries supplying oxygen to the tissues. This can lead to complications in wound healing especially in surgeries requiring elevation of flaps, such as facelifts, breast reductions and tummy tucks. It is crucial to stop using tobacco/nicotine products at least 3-4 weeks prior to surgery and for 4 weeks thereafter. Synthetic cigarettes including vape and e-cigarettes along with nicotine patches and gum are also harmful. Oxygen delivery to tissues is critical to healing and anything that impairs this process will compromise healing. In addition to Nicotine, carbon monoxide is another such harmful substance in tobacco that leads to vasoconstriction. Any surgeon who values patient safety and strives to minimize complications will always decline surgery for patients who have failed to cease tobacco/vape usage. Warm regards, Dr. Pedy Ganchi Village Plastic Surgery
Does smoking affect blood vessels?
Smoking combines the effect of nicotine that constricts the blood vessels and the effect of carbon monoxide that reduces the ability of the blood to transport oxygen to the tissues. This way it creates a combined negative impact on the healing tissues in particular when tension is also involved which reduces the blood flow. For this reason, the World Health Organisation has recently issued a statement indicating that their studies show a minimum of one month of stopping smoking before surgery is necessary to decrease its negative impact on healing.It becomes more difficult to know whether the same is applicable to nicotine in vaping, chewing gum or patches but it is fair to assume that at least part of the negatives of smoking would still be applicable still constriction of the blood vessels. The main issue here is related to the risk of creating irreversible damage in the skin versus the desire to continue using nicotine around the time of surgery. No surgeon wants to risk a poor result and in an elective intervention we try to minimise the risks not only related to nicotine but a multitude of other factors. It would be in your interest to exert your willpower and stop the risk factors that you can rather than to continue the inhalers and expect a lucky outcome.
Does nicotine affect the arteries?
Hello, The answer is "YES"! Nicotine is a vasoconstrictor, meaning it will narrow the arteries supplying oxygen to the tissues. This can lead to complications in wound healing especially in surgeries requiring elevation of flaps, such as facelifts, breast reductions and tummy tucks.
Can nicotine inhalers cause wound healing?
Studies show that nicotine, itself, can cause constriction of the blood flow and result in problems healing your wounds. This gets tricky, as most patients, use these inhalers or patches/gum to quit cigarette smoking. I generally counsel patients to stop all of these products for 4-6 weeks prior to surgery.

What are the ingredients in e-cigarettes?
E-cigarettes come in a wide variety of brands and flavorings and so they may have a giant list of ingredients. But the basic ingredients, propylene glycol and glycerol, are pretty much the same, he added.

Michael Siegel, a professor of community health sciences at Boston University's School of Public Health, who was also not a part of the study, agrees that this study confirms that e-cigarettes, even without nicotine, cause dysfunction in the blood vessels .
Is vaping a cause of heart disease?
But because this effect is short-lived and completely reversible, "it should not be assumed from this research that vaping is a cause of heart disease or permanent blood vessel damage," he said. "Further research will be needed to determine whether vaping poses a risk of irreversible blood vessel injury.".
