Terpene Profile

Terpenes are aromatic compounds produced by many plants including cannabis. They can also be found in food, drugs, and alcohol.

Residual Solvents

Solvents are used in the production of concentrated cannabis products. Trace amounts of these solvents can have adverse health effects and must be removed at the end of the extraction process.


There are many different pesticides and growth regulators used in agricultural processes including the cultivation of cannabis plants. These substances can be harmful above certain thresholds.


Mycotoxins are toxic compounds that are naturally produced by certain types of molds. These molds are commonly found in soil, decaying vegetation, and grains. These substances can be harmful above certain thresholds.

Heavy Metals

Cannabis plants can readily absorb heavy metals from soil and growth media. These elements have well-documented negative effects on human health and thus screening for heavy metals is important to ensure the safety of cannabis products.

Water Activity and Moisture Content

Water activity is a measure of the free moisture in a product. The water activity of a product describes its ability to facilitate the growth of microorganisms.

Vitamin E Acetate

Vitamin E Acetate is a synthetic form of vitamin E which has been shown to be harmful if inhaled. It is a strong culprit of concern when used as an ingredient in vape cartridges and studies have linked it to pulmonary injuries.

Microbiological Contaminants

Microbial pathogens can contaminate water, food, air, and other environmental media such as cannabis. Due to the diversity of pathogens, it is important to test for a wide range of bacteria and fungi commonly found in the cultivation of cannabis.

Products tested include:

  • Cannabis flower
