Data Partners

One coffeeshop menu cannot tell you what the wider market looks like. WeedIndex puts listed prices side by side across the Netherlands. It follows flower, hash, pre-rolls and edibles, with comparisons by city and over time. The headline numbers are medians: the middle prices, rather than averages pulled up by a few expensive outliers. That makes the figures useful for spotting differences, but they remain published menu prices, not a live stock check or a promise of what you will pay at the counter.

PASS THAT HAZE was never meant to stop at addresses and opening hours. Visitors also want a sense of what cannabis costs and why prices differ from city to city. WeedIndex was already tackling that question with a clear method. Rather than build a second price index from scratch, we got in touch and discussed how to work together. We were given permission to use the data and a dedicated partner API endpoint. We show the national index with clear attribution; WeedIndex remains the place to explore the full figures and the method behind them.

Coffeeshop Menu starts with the menu itself. You can browse by city or coffeeshop and look through recently published menus. The site also brings together practical shop details and filters for things such as card payments, parking and accessibility. Visitors and shops can submit new menus, helping the collection keep pace with changes on the ground. A menu is still a snapshot of a particular moment: prices, products and availability may have changed since it was posted.

A useful coffeeshop guide should tell you more than where the front door is. People also want to know what a shop has put on its menu. Coffeeshop Menu has spent time gathering exactly that information. We contacted the owner and received permission to use data from the platform. Dedicated partner API endpoints were also set up for PASS THAT HAZE. They allow us to connect relevant menu information to our own guide while clearly crediting its source.
