Description

Summary

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

Official Title

Extended Intervention for Tobacco (EXIT) Use for People Experiencing Homelessness

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 tobacco treatment with 6 month supply of NRT and coaching for 6 months.
  • Control group: receives tobacco treatment with 3 month supply of NRT.

Participants will be follow-up at 3 and 6 months.
