Some of the immediate effects of passive smoking (second hand smoke) include eye irritation, headache, cough, sore throat, dizziness and nausea. Adults with asthma can experience a significant decline in lung function when exposed, while new cases of asthma may be induced in children whose parents smoke.\n\nShort term exposure to tobacco smoke also has a measurable effect on the heart in non-smokers.  Just 30 minutes exposure  is enough to reduce coronary blood flow.

Smoking produces major changes in the flow of “feel good” chemicals between brain cells, both temporarily and long-term. And those changes in flow match up with changes in how smokers say they feel before and after smoking.\n\nIt's the first time smoking has been shown by positron emission tomography (PET) imaging to affect the human brain's natural system of chemicals called endogenous opioids, which are known to play a role in quelling painful sensations, heightening positive emotions, and creating a sense of reward. It's the same system that is stimulated by heroin and morphine.\n\nAs for drinking...'As for the effects in general, it's the early stages that feel good, of course. Usually, I hate actually being pissed; but the initial feeling of altering my state of mind, of shifting the perspective a little, is very pleasant – I have a sense of stress evaporating, of neuroses fading into the background for a while

Some of the Harmful effects smoking can cause are:\n\n1.straining on your heart and blood vessels.\n\nThe mixture of nicotine and carbon monoxide in each cigarette you smoke temporarily increases your heart rate and blood pressure, straining your heart and blood vessels.\n\n2. heart attacks and stroke.\n\n It slows your blood flow, cutting off oxygen to your feet and hands. Some smokers even end up having their limbs \namputated because of this.\n\n3. causes cancer.\n\nTar coats your lungs like soot in a chimney.A 20-a-day smoker breathes in up to a full cup (210 g) of tar in a year.\n\n4. Emphysema.\n\nEmphysema is an illness that slowly rots your lungs away. Most People with emphysema often get bronchitis again and again, and suffer lung and heart failure.\n\n5. Lung cancer.\n\nLung cancer is caused by the tar in the tobacco smoke. Men who smoke are ten times more likely to die from lung cancer than non-smokers.\n\n6. block blood vessels.\n\nSmoking causes fat deposits to narrow which is why blood vessels become blocked which leads to heart attack.\n\nI could go on and on but i am sure you want an answer today \n1-6 are the most common effects of smoking.

How Marijuana Smoking Affects the Body \n\nAdversely affects normal cell formation. \nProduces feelings of isolation and depersonalization. \nProduces shakes, lack of coordination and headaches. \nMakes any mental or emotional problem worse. \nIncreases the heart rate. \nHas 50 percent more tar per ounce than tobacco. \nDecreases air flow and creates loss of lung capacity in little more than a month of regular smoking. \nProduces chronic irritation of nasal and lung passages. \nCreates precancerous changes in the lungs of smokers in their 20s. \nSuppresses sex drive and sexual performance with prolonged use. \nCan lead to impotence. \nHarms the developing fetus. \nIs associated with increased still births, neonatal deaths, decreased birth weight and abnormal reactions in children born to mothers on marijuana. \nDecreases brain response, affects thinking and brain function, creates confusion and problems with short and long term memory, and distorts perception of time. \nCauses blackouts. \nImpairs driving skills. Studies show brake response time is increased, concentration is decreased and risk taking is increased. \nDistorts peripheral vision, especially in the first two hours after using. \nPeople who smoke marijuana generally have reduced energy, reduced motivation and decreased drive. Marijuana twists the mind with false moods, chemically induced distortions and unreal perceptions of people and life. Marijuana distorts what is stored in the memory. It lies to the user.\n\nSmoking marijuana decreases the chance for a naturally satisfying life. It is an especially harmful drug for young people. Just when teens and young adults are searching for motivation and the best way to achieve their dreams, marijuana robs them of motivation. Young people do less, learn less and become less capable when they smoke marijuana.\n\nSmoking marijuana drains self-confidence and arrests the development of confidence in a person's own ability to get natural rewards out of life. Because marijuana introduces people to altered perceptions and feelings, and an "I don't care" attitude, the drug encourages use of other drugs and sinks its users into an ever-deepening dependence on drug lifestyles. Drawn into the illegal drug culture, users are then available to those who are pushing other drugs.

Smoking, whether it is in the form of cigarettes, bidi, cigar or hookah, is a form of nicotine addiction. All of them are harmful. It can cause cancer and damages the lungs and the respiratory tract.\n\nCigarette smoking is a major cause of preventable deaths worldwide. On an average, people who smoke die 5 to 8 years earlier than people who dont smoke. Tobacco users, and people who live with smokers, have nearly all cases of lung cancer. Their risk of developing throat, mouth, oesophageal, pancreatic, kidney, bladder, and cervical cancer is several times greater than for people who are not regularly exposed to tobacco smoke. Smoking is the major cause of emphysema, a debilitating lung disease which slowly destroys a persons ability to breathe normally. Smoking is especially hazardous for people with heart disease, blood vessel disease, diabetes, high blood pressure, high cholesterol or a family history of these diseases.\n\nSmokers, and those living with smokers, have a two times greater risk of fatal heart disease. Smoking also increases the risk of having a stroke. Women, especially those over 35 years old, who take birth control pills and smoke have an increased risk of stroke or heart attack. Increased blood pressure is another danger of smoking. Smoking also decreases HDL (the good cholesterol) levels. Smokers and people living with them have a two to three times greater chance of having peptic ulcers. Smokers also have a greater than average risk of hip, wrist, and fractures of the spine. In addition, smoking also complicates sleep disorders. Smokers also tend to get colds and other respiratory tract infections more often than nonsmokers.\n\nTobacco smoke is dangerous to nonsmokers. Exposure to the smoke, also called passive smoking, increases the risks of nonsmokers getting the same problems as smokers. A nonsmoker in a very smoky room for 1 hour with several smokers inhales as many bad chemicals as he would inhale by actually smoking 10 or more cigarettes himself.\n\nSmoking affects pregnant women and their unborn children. Smoking mothers have a greater risk of miscarriage and stillbirth. Children born to women who smoke have lower birth weights on average. They also have more frequent respiratory infections, a higher risk of chronic ear infections and asthma, and less efficient lung function. Children of smokers usually become cigarette smokers themselves. The more cigarettes a person smokes each day, the greater the risk of disease. Cigar and pipe smokers are at the same risk for cancers of the mouth, lip, larynx, and oesophagus as cigarette smokers. Fortunately, when a smoker stops smoking many of these risks decrease. Users of snuff or chewing tobacco (smokeless tobacco) increase their risk of cancer of the mouth. The mouth cancer can develop relatively quickly, within 10 to 15 years of the first use of snuff or chewing tobacco.

The main way it affects it is this.  Smoke particles block up the alvioli in the lungs and that is where the exchange of oxygenated and deoxygenated blood cells take place - the more are blocked, the less oxygen can get into the bloodstream and the less oxygen gets to the body's vital organs.  Cigarettes also contains tar which also blocks up the lungs and small traces of arsenic (a poison) which is stored by the body and builds up over a period of time.  As to diseases:\n\nAsthma, Emphysema, permanently stained teeth and fingers, Gingivitis, Gangrene, chronic obstructive pulmonary disease (COPD), acute myeloid leukemia and cancers of the cervix, kidney, pancreas and stomach; abdominal aortic aneurysm, chronic bronchitis, cataracts, periodontitis and pneumonia, colorectal cancer, liver cancer, prostate cancer or erectile disfunction, increased chances of getting breast cancer, cancer of the bladder, eosophagus, larynx, lung, mouth, throat, linked to chronic lung disease, chronic heart and cardiovascular disease as well as reproductive problems. Expect to die 10 to 15 years earlier than non-smokers. \n\nHope that helps.

Cigarette smoke contains a number of toxic chemicals and irritants. People with allergies may be more sensitive to cigarette smoke than others and research studies indicate that smoking may aggravate allergies.\n\n \nSmoking does not just harm smokers but also those around them. Research has shown that children and spouses of smokers tend to have more respiratory infections and asthma than those of non-smokers. In addition, exposure to secondhand smoke can increase the risk of allergic complications such as sinusitis and bronchitis. \n\nCommon symptoms of smoke irritation are burning or watery eyes, nasal congestion, coughing, hoarseness and shortness of breath presenting as a wheeze.

How Smoking Affects Your Body\nThere's hardly a part of the human body that's not affected by the chemicals in the cigarettes you smoke. Let's take a tour of your body to look at how smoking affects it.\n\nStarting at the Top\n\nAs a smoker, you're at risk for cancer of the mouth. Tobacco smoke can also cause gum disease, tooth decay and bad breath. The teeth become unsightly and yellow. Smokers may experience frequent headaches. And lack of oxygen and narrowed blood vessels to the brain can lead to strokes.\n\nLungs and Bronchi\n\nMoving down to your chest, smoke passes through the bronchi, or breathing tubes. Hydrogen cyanide and other chemicals in the smoke attack the lining of the bronchi, inflaming them and causing that chronic smoker's cough. Because the bronchi are weakened, you're more likely to get bronchial infections. Mucus secretion in your lungs is impaired, also leading to chronic coughing. Smokers are 10 times as likely to get lung cancer and emphysema as nonsmokers.\n\nSmoking and the Heart\n\nThe effects of smoking on your heart are devastating. Nicotine raises blood pressure and makes the blood clot more easily. Carbon monoxide robs the blood of oxygen and leads to the development of cholesterol deposits on the artery walls. All of these effects add up to an increased risk of heart attack. In addition, the poor circulation resulting from cholesterol deposits can cause strokes, loss of circulation in fingers and toes and impotence.\n\nSmoking and the Body's Organs\n\nThe digestive system is also affected. The tars in smoke can trigger cancer of the esophagus and throat. Smoking causes increased stomach acid secretion, leading to heartburn and ulcers. Smokers have higher rates of deadly pancreatic cancer. Many of the carcinogens from cigarettes are excreted in the urine where their presence can cause bladder cancer, which is often fatal. High blood pressure from smoking can damage the kidneys.\n\nThe Results\n\nThe health effects of smoking have results we can measure. Forty percent of men who are heavy smokers will die before they reach retirement age, as compared to only 18 percent of nonsmokers. Women who smoke face an increased risk of cervical cancer, and pregnant women who smoke take a chance with the health of their unborn babies.\n\nBut the good news is that when you quit smoking your body begins to repair itself. Ten years after you quit, your body has repaired most of the damage smoking caused. Those who wait until cancer or emphysema has set in aren't so lucky—these conditions are usually fatal. It's one more reason to take the big step and quit now.

Effects on the Brain\n\nScientists have learned a great deal about how THC acts in the brain to produce its many effects. When someone smokes marijuana, THC rapidly passes from the lungs into the bloodstream, which carries the chemical to organs throughout the body, including the brain.\n\nIn the brain, THC connects to specific sites called cannabinoid receptors on nerve cells and influences the activity of those cells. Some brain areas have many cannabinoid receptors; others have few or none. Many cannabinoid receptors are found in the parts of the brain that influence pleasure, memory, thought, concentration, sensory and time perception, and coordinated movement4.\n\nThe short-term effects of marijuana can include problems with memory and learning; distorted perception; difficulty in thinking and problem solving; loss of coordination; and increased heart rate. Research findings for long-term marijuana abuse indicate some changes in the brain similar to those seen after long-term abuse of other major drugs. For example, cannabinoid (THC or synthetic forms of THC) withdrawal in chronically exposed animals leads to an increase in the activation of the stress-response system5 and changes in the activity of nerve cells containing dopamine6. Dopamine neurons are involved in the regulation of motivation and reward, and are directly or indirectly affected by all drugs of abuse.\n\n\nEffects on the Heart\n\nOne study has indicated that an abuser's risk of heart attack more than quadruples in the first hour after smoking marijuana7. The researchers suggest that such an effect might occur from marijuana's effects on blood pressure and heart rate and reduced oxygen-carrying capacity of blood.\n\n\nEffects on the Lungs\n\nA study of 450 individuals found that people who smoke marijuana frequently but do not smoke tobacco have more health problems and miss more days of work than nonsmokers8. Many of the extra sick days among the marijuana smokers in the study were for respiratory illnesses.\n\nEven infrequent abuse can cause burning and stinging of the mouth and throat, often accompanied by a heavy cough. Someone who smokes marijuana regularly may have many of the same respiratory problems that tobacco smokers do, such as daily cough and phlegm production, more frequent acute chest illness, a heightened risk of lung infections, and a greater tendency to obstructed airways9. Smoking marijuana possibly increases the likelihood of developing cancer of the head or neck. A study comparing 173 cancer patients and 176 healthy individuals produced evidence that marijuana smoking doubled or tripled the risk of these cancers10.\n\nMarijuana abuse also has the potential to promote cancer of the lungs and other parts of the respiratory tract because it contains irritants and carcinogens9,11. In fact, marijuana smoke contains 50 to 70 percent more carcinogenic hydrocarbons than does tobacco smoke12. It also induces high levels of an enzyme that converts certain hydrocarbons into their carcinogenic form—levels that may accelerate the changes that ultimately produce malignant cells13. Marijuana users usually inhale more deeply and hold their breath longer than tobacco smokers do, which increases the lungs' exposure to carcinogenic smoke. These facts suggest that, puff for puff, smoking marijuana may be more harmful to the lungs than smoking tobacco.\n\n\nOther Health Effects\n\nSome of marijuana's adverse health effects may occur because THC impairs the immune system's ability to fight disease. In laboratory experiments that exposed animal and human cells to THC or other marijuana ingredients, the normal disease-preventing reactions of many of the key types of immune cells were inhibited14. In other studies, mice exposed to THC or related substances were more likely than unexposed mice to develop bacterial infections and tumors15,16.\n\n\nEffects of Heavy Marijuana Use on Learning and Social Behavior\n\nResearch clearly demonstrate

Here are some facts about smoking:\n\nHalf of all people who smoke will end up dying of a smoking-related problem. (National Institute on Aging)\n\nEach day, over a thousand people in America die because of a smoke-related issue. (CDC)\n\nSmokers die an average of 12 years younger than their nonsmoking neighbors. (NIA)\n\nEach year in America, 100 billion dollars is spent treating people who are sick from a smoke-related problem. (WHO)\n\nA spouse or roommate of a smoker is likely to develop problems from second-hand smoke, including stroke, lung cancer, and even breast cancer. (Vanderbilt University Study)\n\nSmall children who live with a smoker are more like to have asthma. (CDC)\n\n70% of smokers suffer mental disorders caused by their addiction to nicotine. (National Institute of Alcohol Abuse)\n\nNocitine damages a smoker's home -- wallpaper, carpet, and curtains get discolored and have the smell of smoke.\n\nThe average price of a carton of cigarettes is 20-40 dollars. If you smoke a carton a week, that's about 100 dollars a month you're wasting.\n\nAccording to a study by the Australian Medical Journal, smokers generally don't go on as many dates as nonsmokers. Smoking has been shown to stain your teeth, affect your complexion, and leave the smell of smoke on your breath. \n\nAnd if that's not enough, consider this: some 80% of the nonsmoking world wants to ban smoking in public altogether, so in a few years smoking will be all but illegal anyway.\nCigarette smoking in public places causes pollution and poor air quality, which means people with asthma are made sick by their neighbors who smoke.\n\nSmoking is not just a personal decision. It affects your neighbors, your spouse, your children, your pocketbook, your coworkers, and your customers.
