Trait Mindfulness and Progression to Injection Use in Youth With Opioid Addiction.

Background: Many youth initiate opioid misuse with prescription opioids and transition over time to more severe substance-using behaviors, including injection. Trait mindfulness is a potentially protective factor.

Objectives: This is a cross-sectional study characterizing a sample of opioid-using youth by level of mindfulness and examines the potential effect modification of emotion regulation on the relationship between mindfulness and progression to injection opioid use.
