Description

Summary

This study is investigating tobacco use and providing tobacco treatment among people experiencing homelessness in California, in San Francisco and Los Angeles.

Details

PRIMARY OBJECTIVES:

  1. Biochemically verified 7-day point prevalence tobacco abstinence at 6-months follow-up.

II. Use expired carbon monoxide (CO) to confirm self-reports of abstinence using a cut-off of CO ≤5 parts per million (ppm).

SECONDARY OBJECTIVES:

  1. Biochemically-verified 7-day point prevalence tobacco abstinence at 3-months follow-up.

II. Measured at 6-months follow-up, a total number of expired carbon monoxide (CO-negative samples).

III. Measured at 6-months follow-up, longest duration of abstinence (i.e., total number of uninterrupted days abstinent), proportion with 50% reduction in expired CO for those who do not quit smoking.

IV. Use expired CO to confirm self-reports of abstinence using a cut-off of CO ≤5 ppm.

OUTLINE:

Participants will be randomized to one of two groups:

  • Intervention group receives 6 months of pharmacist consultation, monthly delivery of nicotine replacement therapy, and telephone wellness coaching.
  • Control group receives pharmacist consultation and monthly delivery of nicotine replacement therapy for 3 months.

Participants will be followed up at 1, 3 and 6 months.
