Mandatory Testing Before Sale

Alaska law requires that every cannabis product be tested by a licensed independent testing facility before it can be sold at a retail marijuana store. No product may reach the retail shelf without passing a battery of safety and potency tests mandated under 3 AAC 306. Testing results are uploaded directly into the Metrc seed-to-sale tracking system and linked to the product's batch number, creating a verifiable chain of accountability from lab to label.

This mandatory testing requirement applies to every product type: flower, concentrates, edibles, tinctures, topicals, and pre-rolls. Each batch must be independently tested before it is released for transfer to a retail store.

What Labs Test For

Alaska's testing requirements under 3 AAC 306 cover five primary categories, ensuring both potency accuracy and consumer safety:

1. Potency (Cannabinoid Profile)

Labs measure the concentrations of THC, CBD, and other cannabinoids in each product. For flower and concentrates, potency is reported as a percentage of total weight. For edibles, tinctures, and other manufactured products, potency is reported in milligrams per serving and per package. Potency testing ensures that the numbers on the label accurately reflect what is in the product — so a package labeled "5 mg THC per serving" actually contains that amount.

2. Pesticides

Labs screen for a panel of pesticide residues to verify that no harmful chemicals were used during cultivation or remain on the final product. Alaska's testing panels check for common agricultural pesticides that could pose health risks when inhaled or ingested. Products that exceed allowable thresholds fail testing and cannot be sold.

3. Residual Solvents

Concentrates, vape cartridges, and other extracted products are tested for residual solvents — chemicals such as butane, propane, ethanol, and CO2 that may be used during the extraction process. Trace amounts above allowable limits indicate that the extraction or purging process was not completed safely. This is particularly important for products made by Alaska's licensed concentrate manufacturers.

4. Heavy Metals

Cannabis plants can absorb heavy metals from soil, water, and fertilizers. Labs test for metals including lead, arsenic, cadmium, and mercury. Products exceeding safe limits are rejected. This testing is especially relevant in Alaska, where some growing operations may use soil or water sources with naturally occurring mineral content.

5. Microbial Contaminants

Labs test for harmful microorganisms including mold, yeast, bacteria (such as E. coli and Salmonella), and fungal pathogens like Aspergillus. Microbial contamination can pose serious health risks, particularly for immunocompromised individuals. Alaska's climate — with wide humidity variations between seasons — makes microbial testing particularly important for ensuring product safety throughout the year.

The Role of Metrc

Alaska uses the Metrc (Marijuana Enforcement Tracking Reporting Compliance) seed-to-sale tracking system to monitor every cannabis product from cultivation through retail sale. When a testing facility completes analysis of a batch, the results are entered directly into Metrc. Only batches that pass all required tests can be tagged for transfer to retail stores.

This integration means that a product's Metrc tag — printed on every retail label — connects to a complete digital record of its journey: which facility grew it, when it was harvested, which lab tested it, what the results were, and when it arrived at the retail store. It is one of the most comprehensive product tracking systems in any legal cannabis state.

How to Read a Certificate of Analysis (COA)

A Certificate of Analysis is the lab report generated for each tested batch. While COAs are primarily used by regulators and licensees, some dispensaries make them available to consumers upon request. Key sections include:

• Sample information: Product name, batch number, producer name and license number, date sampled, and date tested
• Cannabinoid profile: Concentrations of individual cannabinoids, including delta-9-THC, THCA, CBD, CBDA, and others. Total THC is calculated from THCA and delta-9-THC.
• Terpene profile: When included, lists the terpenes detected and their concentrations
• Contaminant results: Separate results for pesticides, heavy metals, residual solvents, and microbials, with pass/fail determinations
• Overall status: A summary pass or fail for the entire batch

What Happens When a Product Fails

If a batch fails any portion of testing, it cannot be sold to consumers. Depending on the nature of the failure, the product may be destroyed, remediated (reprocessed and retested), or held pending further investigation. The Metrc tracking system prevents failed batches from being transferred to retail stores, providing an automated safeguard against contaminated products reaching consumers.

Independent Testing Requirement

Alaska's testing facilities must operate independently from all other cannabis license types. A testing lab cannot hold a cultivation, manufacturing, or retail license. This independence is critical — it ensures that testing results are objective and free from conflicts of interest. The Marijuana Control Board (MCB) oversees testing facility licensing and compliance through AMCO.

Alaska requires all cannabis products to be tested for potency, pesticides, residual solvents, heavy metals, and microbial contaminants by licensed independent testing facilities under 3 AAC 306. Testing results are tracked through the Metrc seed-to-sale system.
