Part of: Closed coffeeshop chain experiment
Bills, official publications, letters to parliament, motions, reports and academic articles about the experiment — including post-2029/2030 scenarios.
The knowledge base brings together key policy documents, reports and articles that shed light on the cannabis experiment and the regulation behind it — supplemented with explanations of political instruments and the scenarios for the period after 2029/2030.
Scenario development after 2029 / 2030
An amendment (ChristenUnie) tried to push for wind-down of the experiment. In the same vein, it is possible to steer early to prevent the experiment ending without structural follow-up.
Scenarios are developed on the basis of:
- interim reports,
- experience in participating municipalities,
- implementation practice,
- further elaboration of KPIs, criteria and assessment parameters,
- annual monitoring of the experiment.
Key moments:
- Committee debate on drugs policy — 12 March.
- Summer 2026 — first WODC study.
- After summer 2026 — first government response.
- 7 December 2028 — government position.
- 7 April 2029 — end of the experimental phase, start of the six-month wind-down phase.
- 7 October 2030 — possible end of the experiment, unless structural regulation has been introduced.
Amendment vs. motion
Two political instruments through which the House of Representatives steers legislation and implementation — both play a role in decision-making around the experiment.
Amendment
An amendment is a proposal to change a bill. It is submitted during the parliamentary handling of a bill.
- Targeted at changing the text.
- Handled in the House of Representatives.
- Put to a vote.
Example: "The House proposes to replace the word 'may' with 'must' in article 3."
Motion
A motion is a proposal on a topic that does not directly concern a bill. It is a request, statement or instruction to the government or another body.
- Concerns a judgement, request or call.
- May cover any topic.
- Put to a vote.
Example: "The House requests the government to investigate how … and to inform the House about this."
