1 Smoking and Tobacco-Use Information and Health Hazards

2 Smoking Statistics Cigarette smoke contains over 4,000 toxic substances, many of which are known to cause cancer in humans Nicotine dependency through cigarette smoking is the most common form of drug addiction and causes more death and disease than all other addictions combined. Forty percent of teenagers who smoke daily have tried to quit and failed.


4 Constituents of tobacco smoke Tar Nicotine Carbon Monoxide Nitrogen Oxides Hydrogen Cyanide and other ciliatoxic agents Metals Radioactive Compounds Agricultural Chemicals Flavors and other additives

5 Tar The particulate matter inhaled by a smoker from a lighted cigarette. In its condensate form, tar is a sticky brown substance which stains smokers’ teeth, fingers, and lung tissue yellow brown. Nicotine Nicotine is among the most toxic of all poisons. The average lethal dose is between 30 to 60 mg.


7 Carbon Monoxide In large amounts, carbon monoxide is rapidly fatal. It has many toxic effects, but the most important is its impairment of oxygen transportation in the blood. Nitrogen Oxides Causes lung cancer and leads to emphysema.


9 Hydrogen Cyanide Hydrogen cyanide is usually used as a poison in gas chambers. Has a direct lethal effect on the cilia, hindering the natural clearing mechanism of the lung. Other Ciliatoxic Agents: Acrolein Ammonia: used in typical household cleaners Nitrogen Dioxide Formaldehyde: used to embalm dead bodies

10 Metals: (30 metals have been detected in cigarette smoke) Arsenic: usually used in rat poison Cadmium: found in batteries and in artists’ oil paint Chromium: associated with cancer in humans Nickel Radioactive Compounds: Polonium-210: radiation dosage equal to 300 chest X- rays in one year Potassium-40 Radium-226 and Radium-228 Thorium-228


12 Other chemicals: Acetic Acid: hair dye and developer. Acetone: main ingredient in paint and fingernail (polish) remover Benzene: rubber cement Hydrazine: used in jet and rocket fuels Phenol: used in disinfectants and plastics Styrene: found in insulation material Toluene: embalmers glue Vinyl Chloride: ingredient found in garbage bags

13 Agricultural Chemicals: (pesticides, herbicides, fungicides, insecticides) Dieldrin DDT: rat poison


15 Oropharyngeal Cancer Oesophageal Cancer Stomach Cancer Anal Cancer Pancreatic Cancer Laryngeal Cancer Lung Cancer Cervical Cancer Vulval Cancer Penile Cancer Bladder Cancer Renal Parenchymal Cancer Renal Pelvic Cancer Ischaemic Heart Disease Pulmonary Circulation Disease Cardiac Dysrhythmias Heart Failure Stroke Disease

30 Smoke, Why Not? Health Reasons: Avoid premature death Avoid diseases Stay physically fit / stay athletic, do sports Economic Reasons: Avoid an unnecessary expense (40 to 100 pesos per pack) Use your money for other things

31 Social Reasons: Be socially accepted (some people don’t like smokers) Be considerate (smoking affects others around you with second-hand smoke) Be respectable – show will-power and maturity Be attractive (smoking causes yellowing of teeth and fingers, bad breath, unattractive coughing, foul- smelling clothes, impotence in males) Avoid addiction
