Harmful effects of nicotine?!
Question: Harmful effects of nicotine?
What it does to you short term and long term.
Answers:
When a person smokes a cigarette, the body responds immediately to the chemical nicotine in the smoke. Nicotine causes a short-term increase in blood pressure, heart rate and the flow of blood from the heart. It also causes the arteries to narrow. The smoke includes carbon monoxide, which reduces the amount of oxygen the blood can carry. This, combined with the nicotine effects, creates an imbalance between the demand for oxygen by the cells and the amount of oxygen the blood can supply.
Cigarette smoking may increase the risk of developing hardening of the arteries and heart attacks. Carbon monoxide may damage the inner walls of the arteries, encouraging fatty buildups in them.
Over time, this causes the vessels to narrow and harden. Nicotine may also contribute to this process. Smoking also causes several changes in the blood that make clots — and heart attack — more likely.
