The Dutch opium law does not allow advertising for ‘drugs’ (as long as it’s not regulated). Earlier reports showed prosecutor Frits Posthumus demanded repercussions for 5 Coffeeshops. However only three of them were fined (according to the Dutch Parool).
Outcome of the judges’ decision was, (about as vague as 10 years ago) that they are allowed to advertise in a way. Just not in combination of any contact information, they allowed to show/ display them in their establishment, nor are they allowed to distribute/ give them away.. Main motivation behind this outcome was that Coffeeshops- and their business are illegal.
