What the researchers found

Most people using cannabis medicinally in the Netherlands continue to rely on non-prescribed sources. The survey documented patterns of use, motivations, perceived effectiveness, and barriers to accessing the prescribed system, quantifying the qualitative findings from companion research.

Why it matters

This quantitative companion to the qualitative Dutch study (RTHC-07732) provides numbers to support the finding that medical cannabis programs can fail to serve their intended population when structural barriers remain unaddressed.

The numbers in context

Survey conducted January-April 2023. Netherlands context. Convenience sample. Assessed use patterns, motives, perceived effectiveness, and access barriers.

How the study worked

Cross-sectional online survey conducted January-April 2023 using convenience sampling of individuals self-medicating with non-prescribed cannabis in the Netherlands.

What this study cannot tell us

Convenience sampling limits representativeness. Self-selected participants likely biased toward those with barriers to formal access. Cross-sectional design. Online survey may miss populations without internet access.

How to read the evidence

Cross-sectional survey providing quantitative data to complement qualitative findings, but convenience sampling limits to moderate.

When this study was published

Survey conducted January-April 2023 in the Netherlands.

The bigger picture

Together with the qualitative companion study, this research provides a comprehensive picture of why one of the world's longest-running medical cannabis programs still fails to reach most of its potential users.

Questions still open

  • What proportion of Dutch medical cannabis users have tried the prescribed system?
  • Would specific policy changes increase prescribed cannabis uptake?

Common questions

How do Dutch people get medical cannabis?
Despite having a legal prescribed system for over 20 years, most people who use cannabis medicinally in the Netherlands obtain it from non-prescribed sources.
Why is the Dutch system relevant to other countries?
As one of the oldest medical cannabis programs, the Netherlands demonstrates that long-term program existence alone does not guarantee patient uptake, offering lessons for newer programs.
