Does Nicotine Restrict Blood Flow?

Nicotine constricts blood vessels, including those in the skin and coronary blood vessels, but dilates blood vessels in skeletal muscle. Vasoconstriction of the skin results in reduced skin blood flow and reduced fingertip skin temperature.

Does nicotine cause poor blood circulation?

Nicotine causes your blood vessels to constrict or narrow, which limits the amount of blood that flows to your organs. Over time, the constant constriction results in blood vessels that are stiff and less elastic. Constricted blood vessels decrease the amount of oxygen and nutrients your cells receive.

How long after quitting smoking does blood flow increase?

Your blood circulation improves within 2 to 12 weeks of stopping smoking. This makes physical activity a lot easier and lowers your risk of a heart attack.
