This is a two arm pilot study of African American smokers to provide varying levels of side effect management and compliance support during a 12 week treatment period.

Percent Compliance With Chantix
Compliance with Chantix calculated as the total doses taken over the total number of doses prescribed. Adherence was measured by pill counts. Measurements taken during monthly medication refill visits. There was no specific predetermined cutoff number on the scale which determined non-compliance. All results from compliance calculations are included in the table.
