Bulletin | Duplicate Sampling | November 6, 2024

To: Licensees (Marijuana Establishments, Medical Marijuana Treatment Centers)
From: Investigations and Enforcement Department
Date: November 6, 2024
Subject: Bulletin – Duplicate Sampling

The Cannabis Control Commission (“Commission”) issues this bulletin to all Marijuana Establishments and Medical Marijuana Treatment Centers (collectively, “Licensees”).

This bulletin is intended to serve as a reminder of Licensees obligation to collect and submit duplicate samples for testing in accordance with Section 5.4 of the Protocol for the Sampling and Analysis of Finished Marijuana Products and Marijuana Products for Marijuana Establishments, Medical Marijuana Treatment Centers, and Colocated Marijuana Operations.

Duplicate samples are collected to provide verification of representative sampling and laboratory procedures. As such, Licensees must adhere to the following processes:

• Licensees must collect a duplicate sample for 5 percent—one out of every 20—of the representative samples collected for each Marijuana product type.
• Duplicate samples must be taken on the same day from the same product batch.
• Licensees must not identify the samples as duplicates to the Independent Testing Laboratory, for purposes of blind quality control.

The Commission may periodically review testing results, including duplicate samples, to evaluate any variance in the sampling and analysis procedures. This review may be used to inform future policy development to improve current Protocols or lead to enforcement action in instances of noncompliance.
