11. Detox

While trying to figure out why a young patient ( Nicholas D'Agosto ) will not stop bleeding after getting into a car wreck with his girlfriend ( Amanda Seyfried ), House accepts Cuddy 's challenge and goes off Vicodin for a week in exchange for no clinic duty for a month. As House's withdrawal symptoms become severe, his methodology for his patient is more harsh and risky, and Foreman and Cameron are afraid he may not be thinking clearly enough in order to save the patient's life. House does solve the case though by exhuming the family's recently deceased cat and performing an autopsy on it. He finds high doses of naphthalene, which is excreted by termites as a repellent. The patient has been exposed to the poisonous vapors due to a termite nest behind the walls of his bedroom. Final diagnosis: Naphthalene poisoning
