The word 'drugs' is a stretch. Its mainly just marihuana ('just' as for me that's normal as I am Dutch and it is decriminalised here though I myself don't use it). Harddrugs are not acceptable. This sign makes that more than clear in Danish and English [1].

To put that in perspective (I already mentioned marihuana decriminalisation in The Netherlands):

1) Danes go to Sweden to buy cheap liquor because alcoholic beverages in Denmark are more expensive than in Sweden (EDIT: I stand corrected, the other way around, thank you @clan). Same with Danes living near the German border. Alcohol, if abused, is a harddrug.

2) Going down more south of Europe is Portugal who have decriminalised drugs [2].

Wikipedia has more info on Christiania [3].

Denmark is an interesting country for a variety of reasons; they actually have a startup scene as well, and are aiming to be self reliant with regards to electricity.
