First of all the user's entire system would become addicted to extremely high levels of nicotine which would elevate heart beat, and breathing, so they'd need it every day. Then it rots the teeth, and gums, and finally it causes or at least promotes mouth cancer..

very difficult question,indeed!! Not because that there is any doubt whatsoever about the harmful effects of the chewing tobacco...or for that matter any form of tobacco use. Yes, it is a killer !! There are no second opinions about that. Your question is about effects after its regular use for 2-3 years. As a matter of facts, it all depends upon the frequency of its use, the form in which it is used, your own body resistance....and many more complex factors which can not be covered here. Now,I request anybody who has been chewing tobacco to head towards a dental surgeon who would do a thorough oral examination and then advise you accordingly, That visit is very very important because only a professional can find out whether any alarming changes have already occurred in your mouth already or not. Then it is time to say good-bye to the habit alongwith the proper treatment of the ailment. Because they say na that it is never too late to mend. God willing, if everything is fine at the moment, even then this is the best time to bid adieu to this villain because anybody just can predict as to for how long you will not develop any tobacco-related oral disease.
Now, specific to your question....the harmful effects include bad, ugly looking stained teeth, a foul smell, pyorrhoea, loose teeth and of course, pre-cancerous oral changes which can ultimately progress to full-fledged cancer if the habit of tobacco use is not stopped. After they they say rightly even for smoking ....Cancer cures Smoking !!!
Please dont be carried by all this technical jargon. Just leave this habit just now.....and just have a oro-dental check by some dental surgeon. Good Luck !
Trust me, it is only your will power which will help you in quitting this habit. You may feel slightly uneasy just for 3-4 days after that you will enjoy a new bliss in your life !! You can keep some Saunf or chhoti elaichi handy for your strong cravings !!

By the way, this advice is coming to you who has been seeing the misery of the tobacco related oral lesions in his patients for more than last two decades.

I just quit a long time habit-on my 6th day using Nicorette. Also started lifting weights again and feeling optimistic about my future. It's hard to have a good outluck on life when you are killing yourself and treating your temple with disrespect.

Tobacco is a losing game, and it really should be outlawed. Murder is legal-one cig or chew at a time.
