Is nicotine a vasoconstrictor?
As a vasoconstrictor, nicotine has this effect on the blood vessels no matter what form it’s ingested.

What does vaping do to your vascular system?
Coronary artery disease and circulatory problems were also higher among vape users. Research has also shown vaping immediately stiffens and tightens your blood vessels, which limits the movement of oxygenated blood to and from the heart to other parts of the body: a true life necessity.

Nicotine caused only a mild and transient vasoconstriction of the cerebral circulation, mediated primarily by stimulation of the superior cervical ganglia, and a small direct cerebral vasoconstrictor component.
Is smoking a vasodilator?
These findings extend previous observations obtained in the brachial artery to coronary arteries, suggesting that smoking is associated with a generalized endothelial vasodilator dysfunction.

Vasoconstriction and vasorelaxation in isolated perfused human skin flaps (approximately 8 x 18 cm) derived from dermolipectomy specimens were asse …
What Will Vasoconstriction Do?
I’ve already touched on the basic principle behind what a vasoconstrictor does in as much as it causes a narrowing of the blood vessels and an increase in blood pressure. But beyond that, what else will happen within the circulatory system when this occurs? Here are a few additional things to understand.

Left unchecked, high blood pressure can cause serious health problems, including damaged arteries, heart disease, metabolic syndrome, and more. Blood pressure alone is a major health risk, and enhancing its severity through the use of nicotine is something that should be avoided.
Does nicotine cause cholesterol?
Nicotine also causes the body to release fat and cholesterol when it enters the blood stream. This means that you have an increased amount of cholesterol flowing through the circulatory system, which in turn means that there is an increased chance of your cholesterol levels building up.
Does nicotine affect blood pressure?
The first thing to clear up what nicotine does to the vessels themselves. Nicotine is a vasoconstrictor that causes the blood vessels to shrink and tighten up. This in turn has a big impact on the blood pressure. Since vessels are smaller, blood pressure rises and brings with it a wide range of health risks.
Does nicotine cause fetal undernourishment?
When nicotine is used, those same blood vessels are narrowed just like any other in the body. This leads to fetal undernourishment and has been linked to a wide range of health problems for unborn children including: Increased risk of obesity. Increased risk of diabetes. Increased risk of facial clefts.
