You chew nicotine gum as a way to help yourself quit using tobacco. The gum contains nicotine and feels and looks like chewing gum. When you chew the gum, the nicotine begins to slowly release into your mouth. Then you hold the gum in your mouth between your cheek and gums.
Cigarette smoke passes nicotine almost instantly into the blood through the lining of the lungs, and the blood takes it to the brain in a few seconds. The nicotine in the gum takes several minutes to reach the brain. This makes the "hit" less rapid with the gum than with a cigarette. Nicotine gum also delivers much less nicotine to your body than a cigarette would.
Nicotine gum comes in several flavors and in two strengths: 2mg and 4mg. Start with the 4mg strength if you smoke 25 or more cigarettes a day or if your doctor recommends it.
Do not chew nicotine gum like normal gum. Instead, use the "chew and park" method:
It is possible to become dependent on nicotine gum, but this is rare.
Nicotine gum does have side effects. Read the package insert before you use this medicine.
