Chewing gum must contain a gum base, such as polyethylene and polyvinyl acetate. It also contains sweeteners and softeners such as sugar and glycerin or vegetable oil.

Well there is chewing tobacco. Cigars and cigarettes are forms of smoking tobacco.

This prohibition started progressively, there is no a fixed date for that Law. May be the last decade of the XX century.

well if you mean chewing tobaco it can cause much more problems then nomal cigerettes because your holding it in your mouth cause damage to your gums and teeth.

Want good cigarettes chose them from www.cigs4girls.net

If you're asking what the name of the chemical active in tobacco, which gives the rush and euphoria, its called Nicotine.

To understand why it is hard to quit smoking, you have to understand how it works. Tobacco is usually smoked, so we'll look at that method.

First, the smoke enters your lungs. The smoke is absorbed into the bloodstream, through the heart, and into the brain within a matter of seconds. Once inside the brain, it activates a chemical response which triggers the release of dopamine and endogenous morphine (Endorphins). These chemicals are responsible for the euphoria and general feeling of calmness and reduction of stress. Dopamine is the brain's key chemical in the reward system; it is released with endorphins after eating (especially foods high in sugar), sex, exercise, and accomplishment.

Once nicotine becomes an everyday supplement, the brain begins to slow the production of endorphins. This is because the brain now believes that nicotine is a superior substitute to generating its own, so you are now required to intake nicotine to release a normal amount of endorphins.

Since the levels of dopamine were being altered, the brain also slows down the transmission of dopamine via synapses. In combination with low endorphin count, you cannot function normally (at least happily). You begin to notice that you cannot enjoy the things that you used to love beforehand as much.

The effects of nicotine withdrawal are decreased motivation, pleasure, concentration (dopamine levels), irritability, depression (serotonin levels), intense cravings (low levels of dopamine and endorphins).

Once you are hooked on nicotine, you basically have a disabled natural rewards system; the only reward system is in the cigarette/snuff/whatever. A fine taper of nicotine (gradually lowering the dose) can help slowly balance the chemicals in the brain.

Another reason is simply because it is a social event. You see people smoking, you have to smoke. You talk to them, you're friendly, etc because of the surge of endorphins.

My interesting idea for why we smoke when we do (after eating, work, sex, etc) is because those are natural times when brain chemicals are released; accomplishment. Since the brain doesn't produce much of its own anymore, the tobacco must provide it. It sends signals of epinephrine (adrenaline), which is the jitteryness or strange feeling in the heart when you are craving a cigarette.

I've been hooked for a long time now. It costs more to quit than it is to smoke. Patches are at least $200 for the complete kit (week 1, 2, 3, etc). Plus the long-term success rate of patches are relatively low; something like 70% of former smokers relapsed within a year of quitting on patches.

Cigars

I don't know much about the colonies, but I do know tobacco changed Jamestown a whole lot. John Rolfe started growing tobacco, and got a bunch of different types. A few types sold really well and got the colonies a bunch of cash.

Contrary to popular belief smokeless tobacco is not as harmful to you as once thought. It has not been linked scientifically to oral cancer, unlike smoking. The combo of smoking and drinking is a major cause of cancers in the mouth, throat, etc.

From tobacco plants. Its cut, dried and additives are well....added. But dont do it. Its very bad for you.

Yes, you definitely can get tongue cancer by chewing tobacco. You also increase your chances of getting mouth cancer. Chewing tobacco gives you stained teeth, bad breath, gingivitis, gum ulcers and worn down teeth.

I would assume so, yes. When you smoke from a pipe, residue from the marijuana or tobacco (or whatever you're smoking) builds up in the pipe, in the form of a thick black tar-like substance called "resin." That is the same stuff that is also building up in your lungs...

Anyway. Marijuana smokers will often scrape this resin out of their pipes when it builds up, and smoke it, thus making their weed supply go farther and saving themselves some money.

Often it is possible to just smoke the pipe "dry," as in, with nothing in it. Since the resin often builds up in the bowl of the pipe (the place where you put the marijuana or tobacco), you can often just light the pipe dry and get a few hits.

So, if you put tobacco in a pipe that had weed in it, you will end up smoking a little bit of the resin from the weed, every time you light the pipe. So there is a pretty good chance you will fail a drug test afterwards.

The main chemical in all plants is cellulose, with a mixture of other polysaccharides. Then there are water, carbon dioxide, nitrogen, etc.

All plants synthesise a number, usually around 40-100, of allelochemicals to ward off predators, for reproduction, etc. Nicotine is one such allelochemical produced by the tobacco plant (and in smaller quantities by the potato, tomato, bell pepper, egg-plant and some teas).

All of the quoted 'nasties' like mercury, arsenic, lead, polonium, etc. are absorbed from the environment, as is equally the case for ALL plants, including 'healthy' fruit and vegetables.

CANCER OF THE LIPS,MOUTH ,GUMS ,TONGUE,THROAT, ESOPHOGUS, AND STOMACH

all of that stuff is really bad for u and it can rote ur lip off

and your lungs will be blocked by tar from the smoke you inhail which will limt your amount of exercise you do in the furture.

A book would be needed to list the harmful effects of tobacco on the human body but I presume you are referring to smoking.

Tobacco contains nicotine which is a very addictive drug and very toxic. The nicotine in a packet of cigarettes is capable of killing a man or a woman. Tobacco smoke has well over 100 harmful chemicals in it and most are cancer forming.

Nicotine has the effect of constricting the blood vessels thus making the heart work harder and reducing the blood flow. Small blood vessels such as those on the face will be affected and cause wrinkles prematurely. The tiny blood vessels in the macula (the area on the retina at the back of the eye that pinpoint what is being looked at can degenerate due to blood starvation leading to permanently impaired vision. Blood starvation in the lower limbs can lead to leg amputation and the fatty deposits in the arteries lead to higher blood pressure, heart attacks and strokes. Only about 40% of tobacco smoke inhaled will be exhaled. The rest remains in the lungs and sticks to the lung membrane leaving a thick tarry cancer forming deposit which destroys the small hairs that clear the lungs of dust, and air impurities and reduces the lung's efficiency. Added to this, tobacco smoke contains carbon monoxide which actually grabs the oxygen already in the blood stream so reducing the blood's ability to carry oxygen around the body. Is this enough? I could go on and on and on.

Every cigarette smoked shortens life by eleven minutes and 80% of smokers die of smoking related illnesses and the rest have a reduced quality of life.

The human lungs are simply not designed to cope with dense poisonous smoke being drawn into them day in and day out. Many far less dangerous substances have been banned on the grounds that they are harmful to health and are cancer forming but STILL people smoke.

Cancer is a very lonely disease and a smoker who gets it is on his/her own. If it is contracted in the lower lung the prognosis is dire.

A non smoker saving the cost of a packet of cigarettes a day from the age of 20 to 60, could accumulate around one million pounds if the money is put in the right place! How is that for a pension fund?

Finally, it is no good a smoker arguing against the statistics. I am not one to believe all the stupid reports we read about, that emanate from two bit researchers, but the evidence we have is built up from the Surgeon General's report "Smoking and Health" which was published over fifty years ago and has been built on ever since.

Fortunately, help is at hand if the above does not put a smoker off the habit. The NHS and others have ways of helping smokers give up but the best advice is "Don't start in the first place."

Depending on the Dosage, Nicotine is can be either a Depressant and Stimulant. With a low dosage it is a stimulant, where as with higher dosages it becomes a depressant.

Most people i know say that baseball players chew tobacco or something like that, but as a baseball player myself i think its not true because if they do they would come out positive in the drug tests. When i play i ither chew gum or eat flower seeds, but i keep away from tobacco.

The MLB does not test for tobacco....it's legal and non-performance enhancing.

Wisdom teeth removal results in holes in each of the extracted tooth sockets. These holes take several weeks to completely close. Although using snuff is a bad idea in general, it would be wisest to not use the product at all until the holes have closed completely.

tobacco has a very addictive drug called nicotine. Nicotine is a stimulant that has many side affects. Not only that but tobacco has other bad components such as tar that can line the lungs when burned and smoked.

NO. People may believe that smoking kills you, and it can, but they make their own choice to smoke. If there is a death caused by smoking, there realy isn't anyone to blame except the smoker his/herself. Lay off the companies, but if there's no Surgeon General warning on the advertisement, then you may have a case there.

It does extremely disgusting things to your body. Tobacco effects the function of your lungs and if your lungs don't work properly then toxin particles in your lungs won't be cleared efficiently which can lead to respiratory diseases like lung cancer and emphysema.

Also, tar collects in your lungs. (yuck!!) tobacco also stains teeth, causes bad breath and decreases the ability to smell and taste. AND

The carbon monoxide and nicotine found in tobacco may cause throat, mouth and esophageal cancers.

So yeah, don't try tobacco.

There are many ways. You can either quite cold turkey or try to ween yourself of of the product.

I dipped for a couple years and wanted to stop. Sometimes I would quite cold turkey and others I would ween myself off by lowering the amounts I allowed myself to have each day. I have found that quiting cold turkey takes a lot more will power and you are more likely to fail. I failed a couple times when I got in a stressfull time or just felt like a pinch would feel great. I have been free of dip ever since I weened myself off of it and it has been a few months. This will probably be your best bet b/c you won't have the cravings from the nicotine receptors that you would quiting cold turkey.

I took up chewing gum or drinking coffee to help during quiting and that helped a lot. just having something to chew on like a straw or gum will help.

Whatever your choice, stick to it. the first week is hell but if you can get through that, the rest should be easier. Good luck
