Overview

The goal of this clinical trial is to use contingency management (CM) as an intervention tool to address methamphetamine use.

The main objectives are to:

• Gather effectiveness data on a pilot a CM program for participants in Hawaii who use methamphetamine following hospitalization due to traumatic injury
• To assess participant perspectives on engaging with a CM program based at a Level 1 Trauma Center. Researches will assess both patient-reported and biologically-confirmed medium-term program effectiveness and conduct qualitative interviews with participants post-program.

Participants will:

• Visit a follow-up clinic up to three times per week to complete urinalysis following discharge from the trauma unit
• Complete Treatment Effectiveness Assessments at 6 and 12-weeks
• Engage in a qualitative interview at the end of the CM program
