Further study details as provided by University of Oklahoma:

Primary Outcome Measures:
  • Change in Child Salivary Cotinine [ Time Frame: 3, 6, and 12 weeks ]
    Child salivary cotinine will be measured to assess the level of secondhand smoke exposure. We will measure the change throughout the study.

Secondary Outcome Measures:
  • Change in Parent and Child Lung Function [ Time Frame: 3, 6, 12 weeks ]
    We will collect both parent and child spirometry data and compare changes.

Enrollment: 74
Actual Study Start Date: November 2012
Estimated Study Completion Date: October 2017
Primary Completion Date: March 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Counseling
Experimental: Nicotine lozenge
Participants will receive nicotine lozenge to use as needed for 12 weeks.
Drug: Nicotine polacrilex
Experimental: Tobacco lozenge
Participants will receive tobacco lozenge to use as needed for 12 weeks.
Drug: Tobacco lozenge
