We examine the political and personal effects of disaster volunteerism with participants of the New Orleans Rebirth Movement (NORM) using four waves of pre- and postsurveys and qualitative analysis of participant journals. Significant increases are found in internal political efficacy, desire to be active in politics, and value placed on social justice issues, but disaster volunteerism also dramatically increases cynicism and emotional distress. Nearly every NORM participant in the study experienced emotional stress, and 1-in-5 self-medicated as a coping strategy upon one's return. Disaster volunteerism holds the potential to rapidly accelerate social justice consciousness and activism, even among those already inclined to be active, but the cost is high. Further research on this unique and increasingly popular type of community-based learning is needed. (Contains 3 figures and 11 notes.)
