This could be via a cigarette, cigar, roll-up, pipe, or hookah (waterpipe). The smoke contains nicotine, a very addictive drug. It also contains tar, carbon monoxide and up to 4000 other chemicals, many of which are toxic or carcinogenic (cause cancer). @ASPSDubai How do you think smoking affect gas exchange system? @ASPSDubai  Ciliated cells Smoking damages the tiny hairs that line the gas exchange system; these hairs are called ciliated cells. These move mucus up that has trapped dust and pathogens out of the airways. This can result in smokers developing a cough to remove this mucus. Smoking also irritates the bronchi which can lead to bronchitis. Smoking also breaks down the lining of the alveoli, which means less gas exchange can occur and can lead to chronic obstructive pulmonary disease (COPD). @ASPSDubai  Smoking CARBON NICOTINE MONOXIDE TAR Reduces the Black sticky Highly addictive amount of oxygen substance that clogs drug that acts that is carried in the lungs and makes directly on the your red blood lung infections more brain. cells. likely.

Cigarettes are made from the dried and cured leaves of the tobacco plant. Nicotine is the key addictive drug in tobacco. Like heroin and cocaine, nicotine changes the way the brain works and causes cravings for more nicotine. Nicotine can be found in: ​ Tailor-made manufactured cigarettes ​ Roll-your-own cigarettes ​ Cigars ​ Pipe tobacco ​ Water pipe tobacco (shisha, narghile), Read more ​ Chop-chop (illegal loose rolling tobacco) ​ Herbal and spiced cigarettes ​ E-cigarettes, Read more What else do cigarettes contain? Research shows that cigarette smoke contains more than 7,000 chemicals, many of which are harmful toxins. These include: ​ Carbon monoxide — this also comes out of car exhausts. ​ Lead, mercury, chromium and cadmium — toxic metals. ​ Hydrogen cyanide — used in larger doses in gas chambers. ​ Ammonia — found in cleaning products and added to cigarettes to increase the nicotine hit. ​ Polonium 210 — a radioactive substance. Some of the toxins in cigarette affect the mouth, throat and lungs, while others travel in the bloodstream throughout the body. The longer a person smokes, and the more often they smoke, the greater their risk of developing diseases such as lung cancer. Sometimes people believe that a certain type of tobacco, such as roll-your-own cigarettes, is more natural and healthier than manufactured ‘tailor-made’ cigarettes. This is not true. Inhaling smoke is harmful no matter what type of tobacco is used. How many young people have tried cigarettes? Smoking rates among school students have fallen greatly since the 1980s. According to the 2022-2023 Australian secondary schools' survey, 1 in 30 students (3%) aged 12–17 reported they had smoked in the past month. What are the effects of cigarettes? Even though smoking is legal, it doesn’t mean that it’s safe, or that it is less harmful than illegal drugs. In fact, smoking is responsible for more deaths than any other drug. Smoking is legal because it was already widely used and socially accepted before the health risks became understood. The effects of tobacco smoking vary, but may include: Immediate Long-term Increased heart rate Dependence (see glossary) Increased blood pressure Dental problems Reduced oxygen to the brain and Premature aging lungs Bad breath Reduced physical fitness Stained teeth and fingers Reduced fertility Shortness of breath Respiratory (breathing) problems Increased phlegm production Increased risk of heart disease (smokers are 2-4 times more at risk) Persistent coughing Lung disease (e.g., emphysema) Constricted blood vessels Diabetes Cancer What are the effects of second-hand smoke? Second-hand (passive) smoking occurs when people near a smoker breathe in the smoke. This is not safe and can have serious health effects including lung cancer and heart disease. Electronic cigarettes (e-cigarettes) Electronic cigarettes (also known as ‘e-cigarettes’ or vapes) are handheld electronic devices that mimic the effects of a tobacco cigarette but produce vapour instead of smoke when inhaled. The use of e-cigarettes is often referred to as ‘vaping’. According to the 2022/23 Australian Secondary School Students' Alcohol and Drug Survey, 30% of young people aged 12-17 have used e-cigarettes. Around two thirds (69%) of these young people had never smoked a tobacco cigarette before trying an e-cigarette. As e-cigarettes are a relatively recent phenomenon, there are no long-term studies that can establish their safety. Because of this, it is unclear whether vaping is any safer than smoking tobacco, and the long-term effects are currently unknown.
