Looks like she doesn't have a prescription nor a reason to need one. It was only 57 pills sent to her, which is far to few to make significant money selling them, which leads me to believe she has an addiction...
According to the report, “a routine health checkup conducted after the arrest of managing officer Julie Hamp on Thursday to examine her health status prior to detention showed she did not have any particular problem.” At yesterday’s news conference, Toyota CEO Akio Toyoda sidestepped questions whether Ms. Hamp was in pain, or whether she had a prescription for painkillers.
Ms. Hamp received a package with 57 tablets of Oxycodone hidden in it, reports say. Oxycodone is categorized as a narcotic in Japan, and is said to be stronger than morphine. Overdosing can produce euphoric effects like heroin.
47News, quoting police sources, says that Ms. Hamp had been in and out of Japan repeatedly since her April 1 appointment as Managing Officer of Toyota, and that she re-entered Japan just prior to her arrest. The Tokyo Metropolitan Police Department Organized Crime Section 5 is said to be investigating why Ms. Hamp received the pills in an international courier package instead of bringing in the pills on herself during one of her frequent trips.
