What effect does nicotine have on you?

Answer 1

Nicotine causes a short period of well-being and a slight increase in energy. Its time of action is very short, which is why people who are addicted have to smoke cigarette after cigarette. Nicotine also causes constriction of the blood vessels. This causes the heart to work harder, the blood pressure to rise and various other problems. Constriction and reduction of blood flow to the outer layers of the skin is why women who smoke heavily have the complexion of an old lady when they are 40.
