Wikipedia
Nicotine gum is a type of chewing gum that delivers nicotine to the body. It is used as an aid in nicotine replacement therapy (NRT), a process for smoking cessation and quitting smokeless tobacco. The nicotine is delivered to the bloodstream via absorption by the tissues of the mouth.
It is currently available over-the-counter in Europe, the US and elsewhere. The pieces are usually available in individual foil packages and come in various flavors. Nicotine content is usually either 2 or 4 mg of nicotine, roughly the nicotine content of 1 or 2 cigarettes, with the appropriate content and dosage depending on the smoking habits of the user. Popular brands include Nicotex, Nicoderm, Nicorette, Nicogum, Nicotinell and Zonnic.
Alternative nicotine replacement products include the nicotine patch, nicotine pastilles/lozenges and the nicotine inhaler.
