I'm currently watching season 3 of House M.D. and I'm a bit confused. He tries to get Vicodin from his coworkers and even visits an external doc but since he is a doc himself why doesn't he prescribe Vicodin for his own use?
House is not allowed to self-prescribe. It is not clear if this is all doctors or just Cuddy's restriction on House, but this is the case. This can be seen a few seasons later when House has to ask Wilson for a legitimate prescription.
