Transcript

  • 1. Ulyafaridah<br /> XII<br /> IPA 2 <br />
  • 2. cigarette<br />DANGER<br />
  • 3. A cigarette is a small roll of finely cut tobacco leaves wrapped in a cylinder of thin paper for smoking. The cigarette is ignited at one end and allowed to smoulder; its smoke is inhaled from the other end, which is held in or to the mouth and in some cases a cigarette holder may be used as well. Most modern manufactured cigarettes are filtered and include reconstituted tobacco and other additives<br />
  • 4. The term cigarette, as commonly used, refers to a tobacco cigarette but can apply to similar devices containing other herbs, such as cloves or cannabis. A cigarette is distinguished from a cigar by its smaller size, use of processed leaf, and paper wrapping, which is normally white, though other colors are occasionally available. Cigars are typically composed entirely of whole-leaf tobacco.<br />
  • 5. Rates of cigarette smoking vary widely, and have changed considerably over the course of history – since cigarettes were first widely used in the mid-20th century. While rates of smoking have over time leveled off or declined in the developed world, they continue to rise in developing nations. Nicotine, the primary psychoactive chemical in tobacco and therefore cigarettes, is addictive. About half of cigarette smokers die of tobacco-related disease and lose on average 14 years of life. Cigarette use by pregnant women has also been shown to cause birth defects, including mental and physical disabilities.Secondhand smoke from cigarettes has been shown to be injurious to bystanders, which has led to legislation that has banned their smoking in many workplaces and public areas. New research has shown that third hand smoke, which is the residue of cigarette chemicals left on clothes, furniture and carpets after second hand smoke has gone, increases the probability of lung-related diseases. Cigarettes are the most frequent source of fires in private homes, which has prompted the European Union and the United States to ban cigarettes that are not fire standard compliant by 2011.<br />
  • 6. What's In Cigarette Smoke?<br /> Cigarette smoke contains over 4,000 chemicals, including 43 known cancer-causing (carcinogenic) compounds and 400 other toxins. These include nicotine, tar, and carbon monoxide, as well as formaldehyde, ammonia, hydrogen cyanide, arsenic, and DDT. <br /> Nicotine is highly addictive. Smoke containing nicotine is inhaled into the lungs, and the nicotine reaches your brain in just six seconds. <br /> Nicotine in small doses acts as a stimulant to the brain. In large doses, it's a depressant, inhibiting the flow of signals between nerve cells. In even larger doses, it's a lethal poison, affecting the heart, blood vessels, and hormones. Nicotine in the bloodstream acts to make the smoker feel calm. <br /> As a cigarette is smoked, the amount of tar inhaled into the lungs increases, and the last puff contains more than twice as much tar as the first puff. Carbon monoxide makes it harder for red blood cells to carry oxygen throughout the body. Tar is a mixture of substances that together form a sticky mass in the lungs<br />
  • 7. Health issues<br />Nicotine, the primary psychoactive chemical in cigarettes, is addictive. Cigarette use by pregnant women has also been shown to cause birth defects (which include mental and physical disability). On average, each cigarette smoked shortens lifespan by 11 minutesand half of smokers die early of tobacco-related disease and lose, on average, 14 years of life.Some of the mineral apatite in Florida used to produce phosphate for U.S.A. tobacco crops contains uranium, radium, lead 210 and polonium 210 and radon.The radioactive smoke from tobacco fertilized this way is deposited in lungs and releases radiation even if a smoker quits the habit. The combination of carcinogenic tar and radiation in a sensitive organ such as lungs increases the risk of cancer. If the smoker also breathes in the asbestos fibers which commonly occur in urban and industrial environments, the risk of cancer is greatly increased<br />
  • 8. User<br />
  • 9. Consumption<br /> As of 2002, approximately 5.5 trillion cigarettes are produced globally each year and are smoked by over 1.1 billion people or greater than one-sixth of the world population. While smoking rates have leveled off or declined in developed nations, they continue to rise in developing parts of the world. Smoking rates in the United States have dropped by half from 1965 to 2006 falling from 42% to 20.8% of adults. In the developing world, tobacco consumption is rising by 3.4% per year.<br />
  • 10. Conclusion<br /> As a cigarette is smoked, the amount of tar inhaled into the lungs increases, and the last puff contains more than twice as much tar as the first puff. Carbon monoxide makes it harder for red blood cells to carry oxygen throughout the body. Tar is a mixture of substances that together form a sticky mass in the lungs. <br />
