Title: Smoking Cessation With Varenicline (Champix) and Integrated Voice Response Technology (IVR)
Brief Summary: The goal of this study is to provide you with an effective treatment for reducing the physical and emotional stress that can occur during the early phase of being without cigarettes. It is our hope that this treatment will help you to stay smoke-free. You will receive counseling and a supply of Champix, a medication to help suppress the symptoms of nicotine withdrawal.

Purpose: To assess the effect of extended Integrated Voice Response (IVR) on smoking cessation after varenicline (Champix) and IVR treatment Hypothesis: There will be significant increase in participants who do not smoke at 1 year if extended IVR is used after 12 weeks of varenicline (Champix) and IVR treatment.

   * deviations which could affect subject's safety (e.g. illness requiring treatment\[s\]) which in the clinical judgement of the investigator might invalidate the study by interfering with the allocated test product or the willingness of the subject to comply with the study activities.
