4. Smoking Assignment In recent years, research has contributed to increased understanding of the effects of smoking on health. The Director of Student Support at the University is concerned that, in spite of this research, students are continuing to smoke, and young people, in particular, are taking up smoking. The Director has requested you to write a report which will provide the following: • information about the health risks associated with smoking, and • recommendations about the most effective way to educate students about these risks.

6. poisoning. Investigators found he and his friend did it to cure boredom, deciding whoever quit the smoking marathon first would pay for all the tobacco. After 40 cigarettes Liu gave up and admitted defeat, but Wu, emboldened by a growing crowd of spectators, kept puffing away, eventually smoking five cigarettes at a time before reaching the fatal 100 mark. Beijing: A teenager from north China who smoked 100 cigarettes in one sitting easily won a bet with a friend, but paid for it with his life when his heart gave out…the 19 yr old.. suddenly lost colour and collapsed after finishing a fifth pack..was declared dead soon after being rushed to hospital. (He) died of a heart attack brought on by excessive intake of cigarette smoke and acute nicotine Smoking

9. Comment from smoking graph……..In chewing nicotine gum, the nicotine concentration increases rapidly at first then the rate of increase slows. It reaches a peak • three quarters of an hour after initial intake, then the level gradually decreases. • If another gum is chewed then the nicotine builds up to a higher level than before. • After three gums the level of nicotine is over 20 nanograms per millilitre. • The main difference between gum and cigarettes is the peak levels of nicotine. The nicotine concentration in a cigarette is twice that of gum at maximum concentrations. OPACS 2002

10. Sentence structure(correct where necessary) • After one hour the nicotine concentration was decreased from 30 to 12 mg. • After one hour the nicotine concentration decreased • The nicotine concentration was jumped to 50 mg • The nicotine concentration jumped • The nicotine can take longer to drop down • The nicotine can take longer to drop • When the smoker smoking, his nicotine concentration levels had a rapid increased • While the smoker is smoking, his nicotine concentration levels increases rapidly • The nicotine inhaled quickly • The nicotine was inhaled quickly

12. What one cigarette does to you • Level of carbon monoxide soars • Pulse increases by up to 21beats per minute; blood pressure rises • Increases tension • Skin temperature drops by up to 5 degrees OPACS 2002

13. Contents of Cigarettes

14. Compare by subtraction • Brand A has 14 milligrams more tar than brand B • Brand A has 1 milligram more nicotine than brand B • Brand A has 5 milligrams more carbon monoxide than brand B OPACS 2002

15. Comparison of brands • Brand A has 8 times as much tar as brand B • Brand A has 10 times as much nicotine as brand B • Brand A has 50% more carbon monoxide than brand B OPACS 2002

16. Absorption of chemicals from smoking Not all of the chemicals in cigarettes are absorbed by the body. For example, a cigarette of brand A contain 16mg of tar, 1.2 mg of nicotine and 15 mg of carbon monoxide. Since some of the above is lost when not puffing, only about 70% would be inhaled. Moreover, not all of these substances are absorbed. This varies, but on average 90% would be absorbed into the tissues. Therefore about 10 mg of tar (16 × 0.7 ×0.9), 0.76 mg of nicotine and 9.5 mg of carbon monoxide are absorbed. OPACS 2002

20. Comment on graph Figure 1 shows the change in heart rate of a participant after having smoked. Before smoking, the heart rate was about 72 beats per minute (bpm). The maximum response was almost immediately after smoking and then dropped quickly after the smoke. The heart rate did not return to normal until about two hours after dosing. OPACS 2002

22. Objectives • Measure and graph pulse rates • Compare tar, carbon monoxide and nicotine in various brands of cigarettes • Draw and interpret scatterplots • Write sentences and paragraphs related to the effects of smoking on health OPACS 2002
