American cigarettes contain about 9 mg of nicotine, I think it's about the same for English ones too.

Marijuanna contains more tar than cigarettes. I believe smoking a joint is somewhere around smoking 3 cigarettes. (This is off of memory from a speach I did in high school, so don't quote me).\n\nCigarettes on the other hand ALSO contain chemicals such as Benzine, Acetolyne, Formaldahyde, and tons of other poisons.\n\nSince most people smoke less joints per day than cigarettes, it is probably the safer option. Definetly if you are in Canada and don't need to worry about being caught.

hey man there aint no easy way. i smoked for ten years and am quit for a year now.  first you have to do it cold turky. no cutting down patch gum or anything. do it only when ur the most motivated and determined. then use all the will power that you have to not take even a hit off another cig, when cravings start chew gum, and work out. If you run it out that works vary well also, just keep yourself busy and you will notice in a few weeks the cravings will start to go away. just remember the key is cold turky if you put nicoteen in your body in any way you will fail its inevitable. remember dieng of lung cancer will suck, good luck.   -clokey

Because by removing nicotine, you've only removed some of the bad stuff.\nAlso people are addicted to nicotine so they only smoke more.

We suspect that there was expression of the 1 subunit in HT 29 cell line after being exposed to nicotine at a concentration of 5 µM, 10 µM and 20 µM

Nicotine itself does not cause cancer. It is all the other stuff in the cigarrettes that cause it.

Actually, did you know that nicotine can help memory and people with dementia.  So to answer your question,  people who smoke are not necessarily retarded.  In fact they be be smarter.  But I would not advocate smoking\nhttp://www.health24.com/news/Alzheimers_and_dementia/1-890,25374.asp\n\ntry googling  nicotine and dementia.

No dear ..It seems that U have been misguided.Nicotine never remains in Lungs..In fact it is absorbed by our pulmonary(lung) veins...so nicotine comes in blood...and this blood when reaches brain, makes nicotine to bind to our brain-nicotinic receptors..which ultimately produces the effects of smokin....But daily smoking  produces some changes in the tissue of lungs which is continous for years can give irreversible lung changes(including cancers)...BUt research has proved n shown that stopping smoking for 10 years approx can bring your lungs to the previous state(non-smoker state)....but this above statement is condition to one thing that in this 10 years , you should'nt have developed the permanent changes..............In all smoking is very bad...But the irony is that I have been smoking for past 6 years....lol

Cigarette smoke contains many things besides nicotine (the addictive substance which gets a really bad rap...). Nicotine affects the nervous system by binding to receptors on nerves called nicotinic receptors.  The result is stimulatory and becomes addictive like other drugs like opiates (heroin, morphine etc.) and alcohol (which produces opiate like substances upon ingestion in many people and especially alcoholics)\n\nUpon burning, tobacco and tobacco paper give off many toxins, some of which are carcinogenic (cancer causing).  In the not so distant past, and even today, additives such as ammonia and other chemicals are added to cigarettes for various purposes.  Tar is a major offender and reeks havoc in the respiratory system (you can take it from me... my cadaver in medical school was Rod Serling).\n\nThe mechanisms that cause cancer are largely unknown, but are a combination of heredity (genetics), environmental exposure, and lifestyle.  Cancer is not one disease but a host of diseases which share as a common factor the abnormal growth of cells and disruption of normal cellular processes.  By far and away, the chief cause of lung cancer is smoking (especially in post-menopausal women).\n\nPeople that smoke their whole life may not get cancer because of a genetic predisposition or protective factor that we have yet to discover, however we do know that the drawbacks of smoking are numerous both on health, life events, behavior, and life events.\n\nJeez.  Who wants yellow teeth, coughing, weight loss, circulatory effects, shortened life span and the whole laundry list of maladies suffered by smokers?  \n\nNot me.  It's not very attractive to boot.

You won't be in as much danger as someone who smokes on a regular basis but this one item should give you pause:\nSmoking one large cigar can be equivalent to smoking an entire pack of cigarettes.\n\n\nThe rest is just added as more info:\nA National Cancer Institute study concludes that smoking one cigar a day even when not inhaling doubles the risk of developing cancer of the esophagus and oral cavity. Cigars emit 20 times more ammonia and 10 times more cadmium and methylethylnitrosamine (cancer-causing agents) than cigarettes.\n\nCigar smokers are up to 10 times more likely to die from cancer of the larynx, mouth and esophagus as nonsmokers. \n\nCigar smokers have lung cancer at a rate three times higher than nonsmokers. \n\nPersistent coughs and phlegm and an increased risk of peptic ulcers and emphysema are more likely in cigar smokers than in nonsmokers. \n\nSmokers who have left cigarettes for cigars are more likely to inhale them, even without realizing it, and get the same exposure levels as cigarettes. \n\nTar and nicotine concentrations are higher in cigars than cigarettes, which can damage the heart and blood vessels and increase risks of heart attack and stroke.

Nicotine is complex in its effect on the body. I doubt if we know all of its effects.  One of the simplest effects is, it is a vasoconstrictor.  It constricts the small arteries.  This is the basis for Beurger's Syndrome, where some people are highly sensitive to nicotine, and if smokers, they often lose their legs to poor blood flow and neccessary amputation.  It is also the reason, smoking can cause high blood pressure, and can constrict your coronary arteries, contributing to heart attacks.  Nicotine from smoking actually has a protective effect against some diseases, namely Alzheimer's disease, Parkinson's disease, and Ulcerative Colitis.  When addictive smokers stop smoking, they have a great deal of difficulty for years trying to think properly to solve problems.  The nicotine has both a stimulating as well as a soothing effect upon the brain.

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 they are not.Even though a cigarette claims to be nic free it still contains a very small amount and still contains tar. It would also promote smoking to underage kids.

Both, because\n\nYou introduce Nicotin into your blood everytime you smoke.\nIt stays in your blood for up to 72 hours which gives you body time to adjust and accept this as a part of your body.\n\nHints the reason that your body will crave more nicotine when your body is low.\n\nNow, Say you want to quit....\n\nAnything after 72 hours every craving is mental, and since its so strong people can still get cravings in similiar situations in which they used to smoke like being with friends, long talks, and drinking years after they initially quit.\n\nI know this is brief, but hope it helps.
