There's a juicy article today about drug deals among the North Korean elite. It also mentions a certain "underground casino" for foreigners at the Yangkag Hotel in Yyongyang. A Google search on this hotel brings up three links--all referring to this article.
North Korea is supposedly a pusher's dream:
One North Korean tradesman ‘H’ revealed, “Drug dealers con North Koreans with money by saying that the ‘medicine’ clears the head and acts as an aphrodisiac by giving you strength. Then they let the buyers taste-test the drug for free.” H said, “After a few times, the majority of these people become addicted and the dealer sets up a relationship to sell the drug for a long time.”The article says the drugs are mostly made in the district of Hamheung, but I'm waiting for the North Korean government to finally put two and two together and blame the CIA for all this debauchery.
