GMP Certification for Medical Cannabis

GMP Certification for Medical Cannabis


What is medicinal cannabis?

Medicinal cannabis (medicinal marijuana) is cannabis and cannabinoids that are prescribed by physicians for their patients. The medicinal cannabis obtained from a pharmacy is a standardized product that meets strict quality requirements. This cannabis is intended for therapeutic purposes, which is why we call it medicinal cannabis.

The cannabis that is dispensed through the pharmacy meets the highest quality requirements and is only intended for use as a medicine. That is why we speak of medicinal cannabis.


The medicinal cannabis supply chain in the Netherlands


The regulated environment of medicinal cannabis in the Netherlands

Since 1 January 2001 the Organisation of Medicinal Cannabis (OMC) has been the government agency responsible for implementing the Single Convention on Narcotic Drugs. The OMC also processes applications for exemptions from the Opium Act relating to medicinal cannabis.

Organisation of Medicinal Cannabis (OMC) = Bureau voor Medicinale Cannabis (BMC).

What is the Office of Medicinal Cannabis (OMC)?

The OMC is the national cannabis office and responsible for:

  • Production of cannabis for medical and scientific purposes
  • Supplying legal medicinal cannabis to pharmacies, universities, and research institutes
  • Ensuring the quality of medicinal cannabis
  • Providing information about medicinal cannabis.

Pharmaceutical quality of medical cannabis

Medicinal cannabis is used as a medicine and must therefore meet a number of strict pharmaceutical requirements. The most important of these is that every type of medicinal cannabis available in pharmacies always has the same composition and also comparable strength.

The cannabis used by the OMC is grown under standardized conditions that are derived from the Good Agricultural Practice (GAP) rules. This ensures that the medicinal cannabis has a consistent composition. The amount of active ingredients is the same in each new crop of a particular product, so that the user always gets a product of the same strength.


Patients safety

Patients, companies and researchers must be able to trust that the product that the OMC supplies consistent pharmaceutical quality and is free of heavy metals, pesticides and microbial contamination. This means that the cultivated and delivered medicinal cannabis must meet international quality requirements and standards.


Testing of medicinal cannabis

Tests are performed to make sure there is no mould, bacteria, heavy metals or other undesirable additions in the cannabis. These quality requirements are documented in the ‘Cannabis flos’ monograph drafted by a certified company in cooperation with the OMC.


Supervision of chain partners (e.g., grower, independent laboratories, logistics service provider)

The quality of the medicinal cannabis is guaranteed by a constant supervision of the grower and the logistic service provider.


Medicinal cannabis supply chain and the applicable regulations


Production (growers)

A professional company cultivates the medicinal cannabis very carefully. This company grows medicinal cannabis in accordance with applicable EU guidelines for herbal medicines.

The OMC contracts the grower through a European tender procedure that anyone can apply for. Strict requirements are imposed on the grower, such as standardized cultivation according to the Good agricultural Practices (GAP) and Good Manufacturing Practices (GMP) guidelines.

The grower must hold an opium exemption and conclude an agreement with the OMC. The grower may only grow what is ordered by the OMC, the entire harvest is bought (provided it complies with the monograph) and physically removed from the grower. The grower is monitored by OMC and IGJ.


Independent laboratories

In order to guarantee to users that the medicinal cannabis of the OMC meets all requirements, independent laboratories test the medicinal cannabis produced for the presence of unwanted substances such as heavy metals and pesticides and for the presence of possible pathogens.

This external laboratory is contracted by the OMC through a European tender procedure. A sample (made by an employee of the OMC) is sent to the lab from every harvest of cannabis. This sample must meet the requirements as laid down in the monograph. The lab is monitored by IGJ.


OMC releases

After approval from these laboratories, the OMC releases the medicinal cannabis for delivery to the pharmacies, universities, and research institutes


Logistic service providers (including with regard to packaging)


The logistic service provider that is used for the packaging and distribution (logistics services) of the medicinal cannabis. Each harvest is collected from the grower in bulk bags after an OMC employee has checked the product and weighed all the bags. These bulk bags are repackaged at the packer in 5 gram jars. A OMC employee checks whether the pots have been properly weighed and the total packaged weight of medicinal cannabis. The packer is monitored by OMC and IGJ.


The logistic service provider takes orders from pharmacists and ensures delivery of the product within 24 hours. The logistics service provider also takes care of the invoicing to the pharmacists. The logistics service provider is controlled by the CIBG, BMC and IGJ.

The requirements for logistic service providers are laid in down in framework agreements. The logistics service provider works in accordance with GMP / GDP guidelines.


Pharmacies, universities, and research institutes

Identified and certified organizations that allowed to order the medicinal cannabis for intended use. These organizations are monitored by the IGJ.
