Никотинова дъвка

No, nicotine gum doesn't produce the same "buzz" as smoking a cigarette. While it does deliver nicotine, it's at much lower levels and slower than smoking, and it doesn't contain the cancer-causing substances found in cigarettes. Nicotine gum primarily helps to manage nicotine withdrawal symptoms and cravings, and it can be used as part of a quit smoking plan. 

Nicotine is absorbed only through the lining of the mouth. It is used differently than regular gum so very little will get in the stomach where it can cause heartburn, hiccups, and upset stomach. Do not swallow the nicotine or your saliva. Let the nicotine be absorbed through your mouth.
