  • 1. Smoking… Thrills but kills
  • 2. Smoking
    • Can be easily defined as the practice where tobacco is burned and the vapors either tasted or inhaled.
  • 3. History
    • Began as early as 5000-3000 BC
    • Some civilizations burnt incense during religious practices which was later adopted for pleasure
    • Tobacco smoking began in South America where it was first cultivated
    • It also became a part of Shamanistic rituals
    • First used to achieve trances and go into the spiritual world
  • 4. Painting of Aztec women being handed cigars before banquet dinner
  • 5. Tobacco
    • It is basically a plant
    • Processed from leaves of Nicotina plant genus
    • Means a pipe which is used to smoke
    • Was first cultivated in South America
    • Mayans were the first to use at as a drug
    • Contains Nicotine which gives smoker a pleasurable feeling
  • 6. Tobacco Plant
  • 7. Nicotine
    • Alkaloid found in Tobacco plants
    • Used as an insecticide as it has antiherbivore chemicals
    • Responsible for pleasurable feeling in smoking
    • Addiction is very hard to break
  • 8. Nicotine
  • 9. How Nicotine works on the body
    • Once nicotine has entered the body, it immediately gets into the bloodstream which means it has access to all the major organs of your body like the brain
    • It triggers the adrenaline hormone to be released which in turn triggers glucose to be released which gives the smoker a short-term energy boost
    • This is one of the many reasons of the smoker’s high
  • 10.
    • Also, almost as soon as nicotine enters your bloodstream, it flows to the brain
    • This is responsible for a part of the pleasurable feeling obtained from smoking it’s also responsible for the withdrawal symptoms and irritability you feel when you try to quit
  • 11.
    • Simultaneously, nicotine suppresses the pancreas release of insulin, preventing the body from re-storing released glucose. This ultimately makes the smoker’s appetite much lower
    • So people think of smoking as also a way to lose weight
  • 12. Side effects of smoking
    • Affects air passages, lungs, alveoli and heart – apart from other things
    • Associated with lung cancer, bronchitis, emphysema, coronary heart disease and ulcers of the stomach and duodenum
    • Pregnant women who smoke more likely to give weight to under-weight babies
  • 13. Smokers Cough
    • In the trachea and bronchi of a smoker, the cilia are destroyed by chemicals in the cigarette smoke
    • Therefore, the lungs become susceptible to bacteria and dust affecting them
    • Also, the number of cilia gets reduced
    • The reduced number of cilia mean that mucus is not swept away from the lungs, but instead remains to clog the air passages
  • 14.
    • This is made worse because the smoke irritates the linings of the airways which causes them to release more mucus
    • The smoker then develops an acute cough which is what is known as the “Smoker’s Cough”
  • 15. Person with Smoker’s Cough
  • 16. Emphysema
    • It kills about 20,000 people a year in Britain
    • Smoke damages the walls of the alveoli, which break down and fuse together again to form irregular air spaces
    • This reduces surface area for gas exchange
    • So, gas exchange becomes very inefficient
  • 17.
    • The blood of the smoker also begins carrying less oxygen
    • This as we all know, is fatal
    • It could lead, in serious cases, to the person being unable to carry out any form of mild exercise like even walking
    • There is no cure for emphysema
  • 18. Lungs affected by Emphysema
  • 19. Lung cancer
    • Evidence of the association between smoking and lung cancer first appeared in the 1950s
    • A survey of people suffering lung cancer was done by a group of scientists. Almost all the patients were smokers
    • So they realised the co-relation between smoking and lung cancer
  • 20.
    • There are 18 drugs, one of which is nicotine, known to cause cancer
    • They are known as carcinogens
    • They are what form tar in the lungs
    • Cancer happens when cells mutate and start to divide uncontrollably, forming a tumor
    • Lung cancer is very hard to detect as it causes no pain in the early stages
  • 21. Lungs
  • 22.
    • Smoking cause cancers not only in the lungs but also in other parts of the body like the larynx, pharynx, esophagus, bladder and many more
  • 23.  
  • 24. Carbon monoxide in smoke
    • It is one of the many harmful substances in cigarette smoke
    • When breathed in, it interferes with the haemoglobin in blood to form carboxyhaemoglobin
    • When this happens, blood carries far less oxygen
    • Therefore, carbon monoxide is a major cause of heart disease
  • 25. Smoking also gives…
    • Bad skin. Because smoking restricts blood vessels, it can prevent oxygen and nutrients from getting to the skin — which is why smokers often appear pale and unhealthy.
    • Bad breath. Cigarettes leave smokers with a condition called halitosis, or persistent bad breath.
  • 26.
    • Bad-smelling clothes and hair. The smell of stale smoke tends to linger — not just on people's clothing, but on their hair, furniture, and cars.
    • Reduced athletic performance. People who smoke usually can't compete with nonsmoking peers because the physical effects of smoking (like rapid heartbeat, decreased circulation, and shortness of breath) impair sports performance
  • 27. This is what you’re putting into your body when you smoke!!!
  • 28. So we should realise that… Cigarettes are killers that travel in packs
  • 29. And… Stop smoking!!!
  • 30. But How?
    • The only way is to stop smoking!
    • Some people are more suited to the immediate quitting approach
    • While others prefer to do it slowly and in bits
    • Also, it’s a good idea to have your reasons for quitting in mind. They will give you the drive to quit
  • 31.
    • Talk to a counselor or look online for resources on how to quit smoking which can help you through the process
    • When quitting, you might find it hard but don’t give up
    • Realise that the first few days of quitting are the hardest
  • 32. Wouldn’t it be nice if we could all do this to our smoking? =)
