Dear Brady, Thanks for posting your query to healthcare magic. Its good that you are trying to quit smoking but-- Poison is poison if taken in any form!! Yes for your kind information kindly do not take nicotine in either smoking or chewing form. By chewing tobacco you can get your inner side of cheek irritation by the chemical it contains and can then lead to swelling. You should be more careful as these kind of irritation are late to appear in tobacco chewing. If swelling is there that means you are more sensitive to this form. So kindly stop it immediately for your better health. You can try Medicated Nicotine patches which are easily available at medical stores to quit all form of nicotine dependence. Best of luck, Dr Sanjay K Kanodia
