What is nicotine polacrilex used for?

Smoking cessation: this is the official name for nicotine "gum," which is really much more viscous (thick) than usual chewing gums. Most people use it to try to stop smoking, although some individuals will just use it to prevent nicotine withdrawal (nicotine 'fits') when they have to fly on an airplane, see a movie or have to be in a non-smoking setting for a long period of time.
