Dr. Michael McNeil, Chief of Administration for Columbia Health at New York's Columbia University, is our guest for this month's episode of "Prevention Profiles: Take Five." During the interview, Michael talks about the differences in how he viewed drug misuse prevention as a student versus now as a professional in the field; some of the top drug-related questions on "Go Ask Alice" (the school's popular online health Q&A forum); his school's naloxone training program, and more.
