Did you Know?

Each state’s appointed government body enforces its own set of testing regulations. There is no one-size-fits-all standard when it comes to cannabis testing. 

→ Legal dispensaries employ licensed, third-party lab partners to do their testing, in compliance with the set standards of each state. 

What occurs during state-specific testing?

Tests and allowable levels determined by each state include the following:

1) Exposure to toxicants:
• Pesticides
• Heavy metals
• Mycotoxins (mold/mildew)
• Residual manufacturing solvents

2) Microbial-specific contaminants:
• E. coli
• Aspergillus (fungus)

3) Non-contaminant testing for:
• Cannabinoid profiling: More than 100 are known and defined; common varieties include THC, THCA, CBD, CBN and CBDA.
• Quantitation of total potency: This determines the percentages and breakdowns of major cannabinoids and their strengths.

There are currently more than 175 cannabis testing labs in the United States.

How does hemp testing differ from marijuana testing? 

When it comes to hemp, the most important test is surrounding THC levels. In the Farm Bill passed in December 2018, the federal government determined that hemp should have no more than 0.03% THC to maintain its legality nationwide.

➔ The USDA hopes to have federal hemp testing regulations in place by 2020.

The cannabis testing market is projected to double in revenue from $1 billion now to $2 billion by 2025.

What does a consumer need to keep in mind regarding cannabis testing and labeling?

Harvest date: Although this does not apply to isolates and concentrates (as product is not cited to degrade), you should not purchase a product that is six months or older. Check packaging for production dates.

Cannabinoids: You’ll likely find ratios of THC:CBD, as these are the most popular and sought-after cannabinoids when purchasing cannabis products. For example, 1:1 indicates equal parts THC and CBD.

Percentages: THC potency is important to note, as it will affect your high. Remaining in the 20th percentile is ideal for new consumers, while seasoned consumers can hit the upper-30 percentiles.

Strain: Every label contains a strain name that you can then research to understand the genetics. This helps categorize the strain as sativa, indica, or hybrid (both).

Ingredients: If you have known allergies, make sure to read all ingredient labels associated with cannabis and its harvest.
