Cannabis in Argentina Gains Public Laboratory in Mendoza

Cannabis in Argentina - When science meets those who produce and those who need care, the path toward quality opens up new possibilities. In the Argentine province of Mendoza, the opening of a public laboratory specializing in medical cannabis expands local capacity to test products and verify their composition—an important step toward strengthening sector oversight and regulation.

In this article, you will see:

• How the new cannabis laboratory in Argentina operates
• Which medicinal products can be tested
• How technology can contribute to quality control
• What is still needed to expand oversight

Cannabis in Argentina: What changes with the laboratory?

The province of Mendoza, Argentina, inaugurated a public laboratory specializing in medical cannabis testing. The facility operates at the Instituto de Histologia e Embriologia de Mendoza (IHEM-Conicet), located at the Universidade Nacional de Cuyo, and was developed in partnership with the Instituto de Sanidade e Qualidade Agropecuária de Mendoza (ISCAMEN) and the provincial Ministry of Government.

According to a report published on the Cañamo portal, this new development for cannabis in Argentina allows authorized producers and projects to conduct testing within the province itself, reducing reliance on services located in other regions.

The initiative expands the scientific infrastructure available to the sector and establishes new conditions to verify the composition of products marketed within the authorized system.

How does medical cannabis testing work in Argentina?

The operational section of the cannabis in Argentina laboratory uses high-performance liquid chromatography with a diode-array detector (HPLC-DAD), an analytical technique employed to separate and identify components in a sample.

According to information from ISCAMEN cited by Cáñamo, the equipment makes it possible to assess the composition and potency of various products, including:

• Cannabis flowers;
• Oils and extracts;
• Resins;
• Creams;
• Pharmaceutical formulations.

The service offers two testing profiles: one covering 16 cannabinoids and another, more limited, with five compounds, intended for routine assessments.

This capability provides a clearer understanding of the chemical profile of samples. In practice, information about composition can contribute to quality control and the oversight of products intended for authorized uses.

Quality control: What is the laboratory's capacity?

According to Mendoza's Minister of Government, Natalio Mema, the equipment can process up to 200 samples simultaneously, with procedures taking approximately 15 minutes.

Conducting analyses within the province itself can shorten the path between production, technical evaluation, and oversight. However, official data on the number of samples actually processed, service fees, or savings generated compared to shipping to other locations have not yet been released.

The laboratory also fits into a broader regulatory organization context. In 2025, Mendoza regulated its cannabis and hemp legislation, establishing rules for the registration and oversight of sector activities.

The new facility adds a scientific tool to this process: in addition to establishing rules, having technical resources is necessary to verify what is present in the analyzed samples.

Medical cannabis: What still needs to advance?

Despite the inauguration, not all announced capabilities are fully operational.

According to ISCAMEN, the system primarily aimed at detecting pesticide residues in very low concentrations has already been installed and verified, but it is still undergoing training, method development, and technical adjustments.

The agency is also working on procedures compliant with the ISO/IEC 17025 standard, the international benchmark for the competence of testing and calibration laboratories. However, this does not mean the facility has already received this accreditation.

The distinction is important: composition and potency testing is already available, while other control fronts remain under development.

What does this advancement represent for cannabis in Argentina?

In a social media post, the governor of Mendoza, Alfredo Cornejo, stated that the laboratory was created to enhance the quality, control, and safety conditions of medical cannabis and industrial hemp in the province.

The initiative brings scientific research closer to regulatory needs and can facilitate the work of authorized producers and projects. For patients and healthcare professionals, however, it is important not to confuse the existence of an analytical infrastructure with an automatic guarantee of safety or clinical efficacy for all products.

The opening represents a step forward in local testing capacity, but its concrete results will depend on the implementation of controls, the consolidation of methods, and transparency regarding the operation of the service.

In a sector where composition and potency are crucial information, strengthening laboratory testing is part of a broader path: bringing together science, regulation, and care, without losing sight of the limits of available evidence.
