He apparently prescribed methadone for her alias, which is illegal:
TMZ obtained documents which show that on August 25, 2006, just 13 days before Smith gave birth, Dr. Kapoor wrote a prescription for methadone. The prescription, RX#2846735, was written for Michelle Chase. TMZ has learned that Michelle Chase was an alias Anna Nicole used. Under California law, it’s illegal to prescribe a controlled substance to a false name.
