The purpose of the Substance Use Prevention Education in the WIC Program project grant is to develop trainings and resources to assist State and local agency WIC staff when addressing substance use prevention and referrals with WIC participants. This opportunity provides funding to develop and deliver a train-the-trainer model substance (i.e., drug and alcohol) use education program for WIC State agencies to deliver to WIC staff, revise the WIC Substance Use Prevention Guide, develop a custom online training course for WIC staff, develop a minimum of two participant education materials, and develop and present outcomes of these four activities to FNS staff.
