S7, E22: Are psychiatric drugs necessary? - In SVU's season seven finale, former rock star Derek Lord (guest star Norman Reedus) goes on a national talk show and lectures about the abuse of psychiatric drugs. Meanwhile, an unstable young woman Jamie Hoskins (guest star Brittany Snow), who loses her virginity, goes off her prescribed medication, gets behind the wheel of a car, and mows down 10 people. As these events are played out in a highly charged way, the argument about prescribed "meds" is challenged. Mariska Hargitay, Christopher Meloni, Tamara Tuni, B.D. Wong, Richard Belzer, Ice-T and Dianne Neal also star.
