Montana state law (Title 50 Chapter 46 Part 3 et seq.) permits cannabis use for those who have established medical reasons. The many forms and potencies of cultivated marijuana make it essential that the grower, dispensary, and patient have a reliable assessment of their cannabis content and quality so that an appropriate patient therapy can be implemented as quickly and as cost-effectively as possible.

There are many aspects to cannabis quality, including:

1. Presence of foreign matter

2. Potency (cannabinoid content)

3. Terpene Profile

4. Moisture

5. Microbes

6. Pesticides

7. Mycotoxins (aflatoxins and ochratoxin A)

8. Metals (arsenic, lead, cadmium, mercury)

The recently signed Montana Medical Marijuana Act (Title 50 Chapter 46 Part 3 et seq.) have allowed licensed operations to test medical marijuana products since June 30th, 2017. The act also requires mandatory testing for medical marijuana products after April 30th, 2018 for dispensaries with more than ten cardholders and for all dispensaries after April 30th, 2020.

What Needs to be tested?

The testing requirements in Montana vary with type of MMJ product and stage of refinement. For example, by the current administrative rules, flower must be tested in lots of no more than five pounds for foreign matter inspection (< 5% stems, < 3% seeds), potency, moisture (< 12%), microbes (< 10 CFU/g), pesticides (various action limits), and mycotoxins (<2 0 ppb). The 5lb lot can have multiple strains, but each strain needs to be tested for potency and moisture. Extracts (such as RSO, BHO, CO2 processed) need to be tested like flower but foreign matter inspection and moisture are not required. Infused products (edibles, tinctures, capsules, and salves) only need be tested for potency provided the source material has been certified.
