WHY NICOTINE IS BAD FOR YOU
• Nicotine is not carcinogenic, but it is highly addictive; after inhalation of smoke, nicotine reaches the brain within 20 seconds and its effects are felt within a minute.
• Nicotine is five to ten times more potent than cocaine or morphine in producing behavioural and psychological effects associated with addiction, including feelings of pleasure, according to a report produced by the U.K.’s Royal College of Physicians in 2007.
• Nicotine dependence is reflected in the difficulty associated with trying to quit smoking. A 2006 report by the U.K. Office for National Statistics found that the majority of smokers (around 70 per cent) want to quit, yet the success rate remains very low. Fewer than 20 per cent of people who embark on a course of treatment to quit smoking succeed in abstaining for as long as a year.
• Nicotine binds to an area of the brain known as the adrenal medulla, which increases the flow of adrenaline. This in turn causes increased blood pressure, heart rate and respiration, and these conditions exacerbate existing heart and blood pressure problems.
• Nicotine can contribute to sleep disorders. It stimulates the nervous system and when taken at nighttime it ensures that the user is alert and awake rather than deep in restorative sleep.
WHY SMOKING IS BAD FOR YOU
• Smoking kills half of all regular smokers.
• Smoking was responsible for 15,500 deaths, or 12 per cent of all deaths in Australia in 2003, according to a government report. If it doesn’t kill you, smoking may severely reduce your quality of life; in the same year smoking caused the loss of 204,700 years of healthy Australian life.
• Smokers are three times more likely to suffer a heart attack than people who have never smoked, a 1990 study by the U.S. Department of Health and Human Services found; each cigarette smoked per day increases the risk by 5.6 per cent.
• Smoking causes nine out of 10 cases of lung cancer and a third of all cancer deaths, according to a 2006 British study.
• Cigarette smoke contains over 4,000 compounds, many of which are toxic and damage our cells. Included in these compounds are acetone, used in nail polish remover; arsenic, often found in insecticides; benzene, a cancer-causing agent; ammonia, used in dry cleaning; and cadmium, which causes cancer of the liver, kidney and brain damage.
• Tar is the main cause of lung and throat cancer in smokers. It stains teeth and skin, and damages the fine hairs in the lungs making breathing difficult and reducing their protective effect against infection. Around 70 per cent of the tar in cigarettes is deposited in a smoker’s lungs.
• A 2007 paper in The Lancet found that smoking causes 73 per cent of chronic obstructive pulmonary diseases (COPD). COPD damages airways and causes them to narrow, making it harder for air to pass in and out of the lungs.
• In people with high blood pressure, smoking may exacerbate the already increased risk of a blood vessel bursting inside the brain, known as intracerebral stroke.

Not reasons...
Most of the 8 reasons "WHY SMOKING IS BAD FOR YOU", aren't.
Instead, they are statistics. Only the "4,000 chemicals" and "Tar is the" bullet points are actual *reasons*.
And the big topic you missed is: sucking burning hot gas and particulates into your lungs clogs up and burns the tissue.
smoke is dangerous
If you paid attention at all in school you would remember if their is a fire you should lay on your stomach and crawl out of the house as not to inhale the smoke get it it is the smoke that kills you cooks your lungs as if they were in a smoker all smoke is a transference of heat from one point to another stop smoking it kills I am just reiterating this persons point
If you paid attention in
If you paid attention in school you would use punctuation.
You might have also learned that smoke is not 'a transference of heat'.
Just saying...
I do, however, like your 'house on fire' analogy. It's true! Smoke is not healthy to inhale. You're doing good in that regard.
Oh, and if you're under 14 years of age I apologize. If that's that case - seriously, you are doing good! Otherwise... sarcasm.
smoke is dangerous
If YOU had paid attention at all in school you would remember that it is "there" and not "their" and it is "lie" and not "lay". And you use periods to complete sentances. These little tricks make your arguement much more effective!!
lol

error
the adrenal medulla is not part of the brain, it is by the kidney. It is composed of modified neurons.
yes, but...
...the question is - modified by whom?

Not Facts about nicotine
This is more about the dangers of smoking than the dangers of nicotine. as a smoker i understand the dangers i have recently switched to the e cig this has already in the past week prevented me from smoking and my health has been increased. I accept that nicotine highers the blood pressure and stimulates the brain but so does gentle excersise. You have only included the "bad" Facts (i use that word loosely as some of your facts are incorrect). Nicotine can also help reduce the affects of depression which is on a massive increase.
The dangers of stopping smoking and/or nicotine replacement
Little mention in all the health journals is made of the weight gain by suddenly denying the body dependent on nicotine.
For myself and many colleagues and associates, Ecigs are the best possible route to avoiding all the known carcinogens in tobacco smoke (eminently proven to cause cancer), but now the UK government is attempting to redefine and "regulate" chemicals containing nicotine - with the exeption of cigarettes !!! In my belief yet another attack on the civil liberties of people choosing an eminently safer alternative that is extremely effective for myself and others, though doubtless driven by the might of tobacco and drugs companies earning millions from monopolised products, hand-in-hand with a government losing revenues from (and heavily dependent upon) tobacco taxation.
When it comes to alcohol though, developing life-long cravings for alcoholics and all the common detrimental social effects, our politicians simply legalise all-night drinking using the mantra of stopping "binge drinking" citing that as the root cause to all ills. Suffice to say, the only thing that has improved are revenues from alcohol.
Oh well, after ten smoke-free months and feeling fantastic with no weight gain or I'll effects, I guess I'll be forced back into smoking again. I find the ignorance and indifference of UK's politicians simply staggering. If anyone suggests I should simply stop, I draw attention to my point on weight gain, though not the issue here.
Good point. Maybe if the
Good point. Maybe if the e-cigarette market grows large enough they could pay off the politicians too.
