Wouldn't it be nice if instead of just bars with alcohol, there were establishments for people to consume cannabis while eating, playing board games, and socializing?
If anything, cannabis seems like a much better (and more profitable) drug around which to build a leisurely establishment.
Some coffeeshops have men with purple hats standing in front, essentially advertising the place. Not to mention all the big signs saying this is a coffeshop, with customers sitting outside on benches and smoking weed in plain sight.
It's definitely possible to find coffeeshops with boardgames, although they are not very popular, since I guess most tourists aren't into that, and most locals can just smoke and play boardgames at home.
Since I'm getting downvoted here: what I wrote is based on my experience in the Zuid Holland region. It might be different in other places of the Netherlands.
