Amsterdam will not take part in the regulated marijuana experiment which started last December in Tilburg and Breda, MPs agreed on Tuesday.

As expected, a majority of the new-look parliament voted against the amendment which would have made the participation of Amsterdam-Oost possible. But a proposal from the far right PVV to put the entire experiment “on hold” was only backed by the three Christian parties and Denk.

The government had hoped to include a big city to assess the impact of regulating the supply chain in a more complex area but all five said no. Amsterdam’s mayor later suggested adding Amsterdam Oost to the 10 smaller cities whose participation was approved earlier.

In the first phase of the trial, cannabis cafes or coffeeshops can continue selling “illegal” marijuana as well as regulated products and not all outlets will have to take part.

Later, all coffee shops in the cities where trials are taking place will be restricted to legal marijuana products only.

The experiment aims to assess if cannabis cafes, or coffee shops, can operate legally by buying the soft drug from official growers. Coffee shops are currently licenced by their local authority but buy the drug on the illegal circuit.

Amsterdam is the only city in the Netherlands where everyone over the age of 18 can buy cannabis products from a coffee shop. Elsewhere, only locals residents can use their facilities.

Ten growers have been given licences to provide exclusive produce to coffeeshops in Breda and Tilburg, and then to coffeeshops in another eight municipalities this year, including Groningen and Maastricht.
