Every time you smoke a cigarette, toxic gases pass into your lungs, then into your bloodstream where they spread to every organ in your body. A cigarette is made using the tobacco leaf, which contains nicotine and a variety of other compounds. As the tobacco and compounds burn, they release thousands of dangerous chemicals, including over 40 known to cause cancer. Cigarette smoke contains the poisonous gases carbon monoxide and nitrogen oxide, as well as trace amounts of cancer-causing radioactive particles. All forms of tobacco are dangerous, including cigars, pipes, and smokeless tobacco, such as chewing tobacco and snuff. Nicotine is an addictive chemical in tobacco. After you inhale tobacco smoke, nicotine flows through the bloodstream to your brain, where it induces a pleasurable feeling. When you repeatedly expose your brain to nicotine, it becomes desensitized, making you crave more and more nicotine just to feel normal. Smoking causes death. People who smoke typically die at an earlier age than nonsmokers. In fact, one of every five deaths in the United States is linked to cigarette smoking. If you smoke, your risk of major health problems increases dramatically, including heart disease, heart attack, stroke, lung cancer, and death from chronic obstructive pulmonary disease. Smoking causes cardiovascular disease. When nicotine flows through your adrenal glands, it stimulates the release of epinephrine, a hormone that raises your blood pressure. In addition, nicotine and carbon monoxide can damage the lining of the inner walls in your arteries. Fatty deposits, called plaque, can build up at these injury sites and become large enough to narrow the arteries and severely reduced blood flow, resulting in a condition called atherosclerosis. In coronary artery disease, atherosclerosis narrows the arteries that supply the heart, which reduces the supply of oxygen to your heart muscle, increasing your risk for a heart attack. Smoking also raises your risk for blood clots, because it causes platelets in your blood to clump together. Smoking increases your risk for peripheral vascular disease, in which atherosclerotic plaques block the large arteries in your arms and legs. Smoking can also cause an abdominal aortic aneurysm, which is a swelling or weakening of your aorta, where it runs through your abdomen. Smoking damages two main parts of your lungs. Your airways, also called bronchial tubes, and small air sacs called alveoli. With each breath, air travels down your windpipe, called the trachea, and enters your lungs through your bronchial tubes. Air then moves into thousands of tiny alveoli, where oxygen from the air moves into your bloodstream, and the waste product, carbon dioxide, moves out of your bloodstream. Tiny hair like projections, called cilia, line your bronchial tubes and sweet harmful substances out of your lungs. Cigarette smoke irritates the lining of your bronchial tubes, causing them to swell and make mucus. Cigarette smoke also slows the movement of your cilia, causing some of the smoke and mucus to stay in your lungs. While you are sleeping, some of the cilia recover and start pushing more pollutants and mucous out of your lungs. When you wake up, your body attempts to expel this material by coughing repeatedly, a condition known as smoker’s cough. Over time, chronic bronchitis develops. Chronic bronchitis and emphysema are collectively called chronic obstructive pulmonary disease, or COPD. COPD is a gradual loss of the ability to breathe for which there is no cure. Cigarette smoke contains at least 40 cancer causing substances, called carcinogens, including cyanide, formaldehyde, benzene, and ammonia. In your body, healthy cells grow, make new cells, then die. Genetic material inside each cell, called DNA, directs this process. If you smoke, toxic chemicals can damage the DNA in your healthy cells. As a result, your damaged cells create new, unhealthy cells, which grow out of control and may spread to other parts of your body. The most common cancer in the world is lung cancer, with over a million new cases diagnosed every year…

    It’s hard to a people to stop smoking when he or she was addicted on that vices but I know someone who can change you to stop smoking if you have faith on Him and his words …God knows how to change you the God in the Bible can help you

  6. Ghostxx Tamimi on November 3, 2022 at 8:59 am

    Why can’t smoking be banned? Why can’t alcohol be banned? Why can’t hash be more strictly banned?

  7. Masagaipou Reamei on November 3, 2022 at 9:02 am

    What would be easier…Giving up smoking🚬 or reducing chemicals

  8. Ferrascarf on November 3, 2022 at 9:03 am

    i wonder why stores sell substances that kills us and is easily accessible…

  9. BY THE GRACE OF GOD on November 3, 2022 at 9:04 am

    Im not saying smoking is good for you and that people should smoke but how can you explain how Actor George Burns smoked cigars most his life and yet he lived to be 100 years????

  12. Bruholojist on November 3, 2022 at 9:10 am

    ı smoke for 10 years and it haven’t made me addicted to it untill now.

  13. Paws Here on November 3, 2022 at 9:10 am

    I don’t smoke. Every person I know that has cancer has NOT smoked. I know smokers in their 80s and 90s who have never had any major illness. Do what the fk you want and stop being a bunch of whinging brats. Nothing is guaranteed and most smokers don’t even get cancer . Worry more about air pollution if you care so much about your lungs, but most of the people who whine about passive smoking drive cars that damage the whole planet. Screw you hypocrites.

    anyone else getting BURG.L vibes from the narrator

  23. Emily S2019 on November 3, 2022 at 9:23 am

    I never have smoked, and never will, for religious reasons. I don’t drink alcohol for the same reasons.
    I even have made the attempt to kick my caffeine habit because I don’t want to let substances in that I will depend on that aren’t necessary, although it’s not said not to have caffeine in my faith other than a no to coffee and caffeinated tea. Another reason I also went to kick my caffeine habit is a family history of congestive heart failure. I don’t want to put more stress on my heart than necessary. I feel that the more I strain my heart via caffeine, the worse the effects of congestive heart failure will be if my preventative measures don’t do enough to prevent it.
    I will allow some caffeine if I absolutely need it, just not on a daily basis any more.
    I exercise to get my heart rate up instead if I can’t kickstart myself.
    I have strong feelings about addicting substances that cause dependency.

    If you smoking, i’m not recomended to smoke a cigarette. The smoking kills.

  29. Bobmac90 on November 3, 2022 at 9:27 am

    This should be on public television fir those people out there who are both e-cigarette smokers and all you vaporing people. You think nothing is going to affect you think again. A strong champagne needs to happen and educate everyone on the dangers!!!! 👿

  30. Kentyox Michael Perez on November 3, 2022 at 9:28 am

    I tried to stop smoking for 1 month 1 year ago ..And I got sick(cough,fever, vomiting and etc)😷 that is why today I can’t stop smoking 🥺

    most of cigar smokers don’t inhale

  33. Happy SIKUBWABO on November 3, 2022 at 9:31 am

    All these organisations and governments are just hypocrites, that’s what they are… First off why not forbid and make illegal producing and selling cigarets? why just require to display on the box that it could be harmful as if that’s the most effective way of creating awareness ? Where is the campain to at least try and bring down the giants who are killing people each year? Truth is, it is a trillion dollar industry, and those benefiting from it could never afford to lose it. This same video, take it to the right place and maybe you could make a change, until then this is just as useless as it is hypocritical.

  34. DickChisqo on November 3, 2022 at 9:31 am

    Does Marijuana have these same effects on the organs?? Or just tobacco

  35. Brians Wife on November 3, 2022 at 9:34 am

  39. Avvoider on November 3, 2022 at 9:42 am

    Inhaling any type of smoke is bad. Smoking is terrible. How do I reason with older people who say "Oh ive been smoking my whole life and at 67 im still alive"?

  40. xko on November 3, 2022 at 9:42 am

    My grandmother was a chain smoker. Had COPD, lung cancer, but still smoked until the day she died. I can’t imagine just how addictive cigarettes must truly be. All I can say is I’ll never try it out, every smoker I’ve ever met has told me to steer clear of it. Speaks volumes.

    The irony is that alcohol kills more than smoking, but no one talks about it 😆
