North Korean Restaurant, Yanji. A North Korean woman gets ready to perform to an audience of Chinese and South Koreans. North Korea is the most isolated, restricted country in the world, which made reporting a story on a taboo subject extremely difficult. Few people, North Korean or foreign, are permitted to travel freely around the country. The only person Newsweek spoke with who claimed the ability to do so, an evangelical Christian, described “miserable starvation, miserable agony” but refused to elaborate on drugs. That said, by cobbling together defector testimony, interviews with experts and on the ground reporting, it’s possible to create a partial picture of the drug’s usage in the Hermit Kingdom. Jilin Province, China. 2011.
