Today, April 7, the Dutch government's cannabis experiment enters a new phase. This marks the final stage of the Closed Coffee Shop Chain Experiment. In this phase, coffee shops in participating municipalities are only allowed to sell regulated cannabis.
Just before the start of the long-delayed trial, the responsible ministries announced that more time is needed to improve hashish production and the purchasing process by coffee shops. As a result, the sale of hashish in participating coffee shops will temporarily not be enforced. This gives growers more time to get their production in order.
Cannabis production has started off well for more and more growers. After a previous visit to grower CanAdelaar, we will now also take a look at Hollandse Hoogtes in Bemmel. A report from this visit to the Bemmel-based grower will follow later.
Purpose of the Closed Coffee Shop Chain Experiment
Currently, the Dutch government tolerates the sale of cannabis (adult-use cannabis and hashish) in coffee shops to consumers. This means coffee shops can sell cannabis under strict conditions without facing criminal prosecution. However, the cultivation of cannabis remains illegal in the Netherlands. This makes it unclear where the cannabis comes from and what its composition is. The aim of the experiment is to investigate whether a closed and regulated chain of cannabis production, distribution, and sale is feasible.
Research
Throughout the experiment, a team of independent researchers will examine the effects on public health, crime, safety, and nuisance. The results of this research may contribute to decision-making on future cannabis policy in the Netherlands. Starting June 10, 2025, enforcement will begin on the sale of illegal hashish in coffee shops, and only regulated cannabis will be permitted for sale.
