Background: Initially considered a primarily rural, White issue, opioid use and overdose rates have risen faster for Latinos (52.5%) than for White, non-Hispanics (45.8%) from 2014 to 2016. With an estimated 45% to 65% of Latino immigrant families using Mexican traditional medicine (MTM) practices before seeking Western medical services, these practices could be used as a method to increase access to care and improve outcomes. Practice Model: Although not well known, MTM is founded on a defined set of theoretical tenets that comprise a whole medical system as defined by the National Center for Complementary and Integrative Health. Whole medical systems are characterized as complete systems of theory and practice that develop independently and parallel allopathic medicine. Classifying MTM as a whole medical system to encourage further research and utilization of traditional and complementary medicine (T&CM) practices could help improve health outcomes for Latino patients. Specific T&CM practices that could be used in opioid treatment integration to decrease stigma and increase treatment utilization are then discussed. Conclusion: Incorporating T&CM practices will allow more effective, culturally competent and culturally sensitive health care provision for Latino immigrants in the United States to decrease stigma, improve health care outcomes, and address disparities in opioid use treatment.
