Implementing a Contingency Management Program Addressing Methamphetamine Use For and With the People of Hawaii

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
