Smoking cessation with nicotine replacement therapy

Nicotine replacement therapy uses products that supply low doses of nicotine. These products do not contain the toxins found in smoke. The goal of therapy is to cut down on cravings for nicotine and ease the symptoms of nicotine withdrawal.

Nicotine replacement therapy is of the most help for people who smoke more than 15 cigarettes a day. It is not yet proven to help people who smoke fewer than 10 cigarettes per day.

Studies show that variants of the OPRM1, CHRNA and ANKK1 genes may influence the effect of nicotine replacement therapies such as the trans-dermal nicotine patch and nicotine nasal spray.
