Talk about how smoking is stupid with everyone at school. Some people are just saying that smoking doesn't matter because they are addicted and can't stop. They know it is bad inside they just don't want to admit it. Try whatever you can to get them to admit it is bad and they will probably stop or try to. These Articles were sent in by Yvonne.
Smoking affects a person's health in many ways, having both immediate and long term effects.
It is a serious addiction, caused by the drug nicotine. Milligram for milligram, the nicotine contained in all cigarette smoke is more potent than heroin. Whenever you light up, the nicotine in tobacco causes an increase in your heart rate and blood pressure, and the air passages in your lungs constrict, making it more difficult for you to breathe. As small blood vessels constrict, your skin temperature may also decrease, causing your fingers, toes and skin to feel cold. Smoking dulls your senses, particularly your sense of smell and taste.
