A story at Vice is proclaiming the most dystopic and secretive nation in the world, North Korea, is actually a pothead's paradise. Well, maybe not paradise, but of all the things you can get arrested for in North Korea, basically everything (for example folding your newspaper because you might accidentally fold a picture of their leaders), marijuana is not one of them.
North Korea has extremely harsh penalty for hard drugs such as meth, but it does not consider marijuana a drug and there is no societal taboo against it. Marijuana grows freely on the side of the road and in residents' gardens.
It is extremely popular among the lower classes especially soldiers in the military. It is often used as a way to relax and soothe the aches and pains after a day of hard labor.
Although, I have to wonder how you handle the munchies when you're literally starving.
