Our Validation Packages in comparison

Remote Audit Validation‍

We conduct virtual sessions to validate your checklist statements by reviewing your SOPs, photos, videos, and perform selected staff interviews.

On-Site Audit Validation‍

Our auditors visit your production site to collect photographic and video evidence of facilities, equipment, and processes. We also interview staff, review QMS documentation, and briefly assess deviations and change management.

On-Site + QMS Audit Validation‍

This package includes all steps from the on-site audit plus a deep dive into your QMS. We assess how SOPs and internal guidelines are applied in daily operations and provide detailed feedback on improving process compliance.

Why Do We Offer Paid Audit Validation Packages?

We do not assume that your company is being untruthful. However, after auditing more than 20 cannabis companies across Europe, Africa, and North America, we have seen that many organizations do not consistently follow their SOPs—some lack compliant processes altogether.

This has led to significant issues across the medical cannabis value chain, triggering authorities worldwide to scrutinize supply agreements and GACP/GMP compliance more rigorously. GMP processing companies in particular must ensure their suppliers meet GACP standards; otherwise, they risk losing their GMP license and must invest heavily to regain trust.

The urgency increased in 2025:

  • In Portugal, nearly all pharmaceutical cannabis production sites were raided by police under suspicion of illegal activities.
  • In Germany, the term “GMP-washing” is now widely used by regional pharmaceutical authorities. As a result, some regulators no longer permit the import or GMP processing of GACP cannabis at all. In fact, the BfArM stated in 2023 that drying must be performed under GMP.

Such non-compliance has undermined trust between GACP producers, wholesalers, and GMP processors—damaging supply reliability and market confidence.
