This is not an issue I was even aware of before, but I can easily see how someone could get in trouble for this without even knowing they were doing something illegal:
U.S. personnel in Japan and South Korea won’t get in trouble if they take prescription or over-the-counter medication off-base, even if the ingredients are prohibited under host-nation law, according to local national officials.
A U.S. English teacher, Carrie Russell, was arrested last month after officials discovered 180 Adderall pills that she had mailed to her new home in Nagoya, Japan. Russell’s mother earlier sent the pills — used to treat attention deficit disorder — to her daughter in South Korea, according to the Tribune News Service.
Adderall, which contains amphetamines, is illegal in Japan and South Korea. Ritalin, the other main drug used in the West to treat ADD, was banned in 2007 in Japan as officials cited widespread abuse.
Pseudoephedrine-based medications sold over-the-counter in the U.S. and at on-base commissaries are also controlled substances in Japan.
Warnings about the import of cold and flu medications with brand names such as Tylenol, Nyquil, Actifed, Sudafed, Advil, Dristan, Drixoral, Vicks and Lomotil are posted on Japanese consular websites. The cold and flu remedies contain narcotic or stimulant ingredients in excess of Japan’s standards, the websites state.
However, officials said U.S. military personnel won’t get in trouble if they take that type of medication off-base.
U.S. Forces Korea spokesman Andre Kok said by email that the Status of Forces Agreement there affords the U.S. the right to furnish medical support for troops, civilians and family members. [Stars & Stripes]
