What is GACP Cannabis Certification?

GACP (Good Agricultural and Collection Practices) cannabis certification in Thailand is a mandatory government certification system that regulates all legal cannabis cultivation in the country. Established by the Thai Food and Drug Administration (FDA), GACP ensures cannabis farms meet strict quality, safety, and regulatory standards.

GACP certification is legally required for any cannabis cultivation operation in Thailand, whether for medical cannabis, industrial hemp, or research purposes. Without this certification, cannabis cultivation remains illegal under Thai law and can result in criminal penalties.

The certification system was implemented in 2022 as part of Thailand’s cannabis legalization framework, designed to create legitimate regulatory oversight while supporting the development of a professional cannabis industry.

Core Elements of GACP

Quality Control Systems ensure consistent product standards through standardized cultivation procedures, regular testing protocols, and comprehensive documentation that tracks every aspect of growing.

Traceability Requirements mandate complete seed-to-sale tracking using approved systems that document plant genetics, cultivation inputs, harvest dates, and distribution channels.Safety Standards protect workers and consumers through proper handling procedures, chemical usage restrictions, and contamination prevention protocols.

Consumer Protection

GACP certification protects Thai consumers by ensuring cannabis products meet established safety and quality standards. The system verifies that farms follow proper cultivation procedures, use approved inputs, and maintain hygienic conditions throughout production.

International Market Access

Thailand’s GACP system aligns with international agricultural standards, enhancing credibility in global cannabis markets and facilitating export opportunities for Thai cannabis products.
