    Smoking Smoking Presentation Transcript

    • Smoking… Thrills but kills
    • Smoking
      • Can be easily defined as the practice where tobacco is burned and the vapors either tasted or inhaled.
    • 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
    • Painting of Aztec women being handed cigars before banquet dinner
    • 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
    • Tobacco Plant
    • 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
    • Nicotine
    • 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
      • 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
      • 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
    • 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
    • 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
      • 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”
    • Person with Smoker’s Cough
    • 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
      • 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
    • Lungs affected by Emphysema
    • 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
      • 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
    • Lungs
      • 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
    • 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
    • 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.
      • 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
    • This is what you’re putting into your body when you smoke!!!
    • So we should realise that… Cigarettes are killers that travel in packs
    • And… Stop smoking!!!
    • 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
      • 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
    • Wouldn’t it be nice if we could all do this to our smoking? =)
