It kills them indirectly.\n\nThe smoking releases a rush of neurotransmitters (the chemicals neurons use to transmit signals to one another) at a much higher rate than normal. \n\nTo keep themselves from being overly stimulated, the neurons let the neurotransmitter receptors on their membranes die off.\n\nAs a person smokes more and more, more and mroe recepts are allowed to die.\n\nWhenever the person is not smoking, the neurotransmitter signals return to normal levels but are not received since the neurons let the receptors die off.\n\nWhen a neuron isn't used enough, the brain pretty much kills it to conserve energy/nutrients for the ones that are used.\n\nThe more you smoke, the more smoke is needed to achieve a high and the more brain cells die afterward.

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. Their are so many, You take a big risk with your health when you start to smoke. I hope i answed your ? to your liking.

A few things I can think of right off my head, without reviewing physiology.  Very basic info here, for more details, you can find it in any good physiology textbook.\n\nSmoke in cigarrettes decreases the capacity for hemoglobin to carry O2, and thus decreases the efficiency for O2 diffusion.\n\nCO2 decreases the surfactant in the lungs, making them less efficient in CO2/O2 exchange.\n\nCO2 also damages cells lining the blood vessels (capillaries) that are important in the diffusion process.

What in the world have you been smoking?  Whatever it is, you need to stop.  It is destroying any brains that you may have had!

I would have to say I know of people of whom i have talked to and or have know from my much younger years and yes they tried both. Marijuana and Tobacco and you don't get any smarter that's for sure. It keeps a person from being able to study or to drive on the roads or to concentrate on much of anything for long periods of time.Although there's not been very much study done on the Marjuana smoking some doctors have been known to prescribe it to cancer patients for to keep them so doped up that they may or may not have alot of pain with their type of cancer so, if you want to play it smart , I SAY DON'T DO EITHER ONE, NOT EVEN TO TRY FOR A SECOND.AS THEY SAY BE SMART DON'T START !!!!!

Effects on the Brain\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 movement\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 use indicate some changes in the brain similar to those seen after long-term use of other major drugs of abuse. 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 system and changes in the activity of nerve cells containing dopamine. Dopamine neurons are involved in the regulation of motivation and reward, and are directly or indirectly affected by all drugs of abuse.\n\nEffects on the Heart\nOne study has indicated that a user’s risk of heart attack more than quadruples in the first hour after smoking marijuana. 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\nEffects on the Lungs\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 nonsmokers. Many of the extra sick days among the marijuana smokers in the study were for respiratory illnesses.\n\nEven infrequent use 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 airways. Smoking marijuana increases the likelihood of developing cancer of the head or neck, and the more marijuana smoked the greater the increase. A study comparing 173 cancer patients and 176 healthy individuals produced strong evidence that marijuana smoking doubled or tripled the risk of these cancers.\n\nMarijuana use also has the potential to promote cancer of the lungs and other parts of the respiratory tract because it contains irritants and carcinogens. In fact, marijuana smoke contains 50 to 70 percent more carcinogenic hydrocarbons than does tobacco smoke. It also produces high levels of an enzyme that converts certain hydrocarbons into their carcinogenic form—levels that may accelerate the changes that ultimately produce malignant cells. 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 increase the risk of cancer more than smoking tobacco.\n\nOther Health Effects\nSome of marijuana’s adverse health effects may occur because THC impairs the immune system’s ability to fight off infectious diseases and cancer. 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 inhibited. In other studies, mice exposed to THC or related substances were more likely than unexposed mice to develop bacterial infections and tumors.\n\nEffects of Heavy Marijuana Use on Learning and Social Behavi

It depends on the person your with. The smoking does make you taste different as well.

Long-term abuse might lead to some problems. You should not get dumb from smoking the stuff occasionally though. My best advice however would be not to bother with the stuff at all. Try video games, girls, and excelling at your studies instead!

I quit smoking back in February.  I smoked about a pack a day for years.  During the withdraw I had a headache for 3 days, and I was grouchy for about 2 weeks.  They say you have to replace one habbit with another.  What I did was started sucking on jolly ranchers and chewing bubble gum.  I also started exercising.  I have never felt better.  I noticed a difference in my breathing after only 2 weeks!!  Just hang in there, and the days will pass and you won't even think about it anymore.  It's also great to go someplace and not worry about being looked down on because of being a smoker.

No, it's not bad.\n\nin fact for many people it's very good.\nRecent studies have shown that it can be of help to Alzheimer's patients.\nI think it depends on how you use it as to how good or bad it is.\nIf you smoke lots every day, I doubt if its very good. But smoked in moderation, like say a couple of times per week, it will have no long term bad effects, and the benefits of not being up-tight can be of great help.\nI know one guy who is 80 years old who has smoked every day for more than 60 years, and he never forgets anything, and is never ill. The short term memory problem is not created by a brain problem. It is created by a lack of concentration at the time of doing things.\nIf it is used as a concentration aid, which it can be, then there are not even short term memory problems. If used in a spiritual way, by being absolutely aware of every single movemnet that is made, and every breath that is taken, then it can be beneficial. Problems arise when used with alcohol, but those problems are mainly alcohol related.

In small doses nicotine has a stimulating effect, increasing activity, alertness and memory. Repeat users report a pleasant relaxing effect. It also increases the heart rate and blood pressure and reduces appetite.

No because when you drink something it gets into your blood stream and smokeing it will have a differant effect, it is absobed differantly. I don't think it will actally do anything to you apart from maybe make you sick

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.

Do you smoke? YES\ndid you used to smoke? YES\nAt what age did you start? 15\nWhy? What was the circumstance? I enjoyed it....initially I thought it looked cool.\nDo you know what tolerance is? Yes\nDid you develop a tolerance? Yes\nHow do you feel when you smoke? Wonderful!\nHow do you feel when you don't smoke? Horrible\nDid you ever try to quit? Nope....\nHow? What method? Did you have help? N/A\nWhy did you quit? I didn't and wouldn't.  I enjoy it too much!\nWhat does smoking do to the body?(what u know-dont search)Relaxes it.  Don't believe all the propoganda that claims it kills you.  If you know anything of science, you know that there were no control subjects in any study done, therefore the science is junk.\nDid you know you could get oral cancer? Yes, did you know that non-smokers can get oral cancer?\nDid you know that it is harmful to the non-smoker? Did you know that 2nd hand smoke is a fairy tale?  Do a little research and you will see that in 1998 the Supremem Court overrulled the EPA's opinion on 2nd hand smoke.  The courts said there was no solid proof that 2nd hand smoke is bad for ANYONE!  I urge you to research this item for your paper.
