vice.com has a nice article on the use of marijuana in North Korea. Despite the well deserved reputation for being a highly controlled society it seems the use of marijuana is rather higher than most might expect. That said it seems there is a rather large difference between how it is viewed there and how it is often viewed by certain groups in much of the rest of the world. Though it is viewed as something of a poor person's vice it seems it is enjoyed by a rather broad section of North Korean society and even finds fans among the military there. http://www.vice.com/read/north-korea-is-stoned-all-the-time-which-explains-a-lot Best Korea.
