The “Practicing Safety Mindfulness Project for Mothers in Drug Treatment” is a federally funded multi-faceted intervention aimed at reducing the toxic stress children of families with substance use disorders endure. One dimension of this intervention is the implementation of a 12-week mindfulness based parenting intervention for mothers of children aged 3 to 36 months. This workshop describes the integration of mindfulness into an opioid treatment program. Participants will also experience mindfulness-based stress reduction practices. Lastly, findings and results will be provided that demonstrate the effect of the intervention on individual psychosocial, parenting, and maternal domains.
