Make informed choices about the quality, viability, health risks, and effectiveness of cannabis and hemp that you produce, process, or consume.
Cannabinoids are chemical compounds found in cannabis, hemp and hops. These compounds, also known as phytocannabinoids, are found in the highest concentration in the flowering portion of the plant, specifically within the resin glands located on the flower. At Green Leaf Lab, we test for 14 different cannabinoids.
Terpenes are the flavor and aroma compounds found in plant resins. There are thousands found in the plant kingdom and more than 100 known to be in cannabis alone. Terpenes are the chemical compounds that provide the aroma and flavor of cannabis varieties, such as earthy and spicy or sweet and fruity. Terpenes are known as the “fingerprint” of a cannabis strain. Green Leaf Lab currently tests for 42 terpenes.
Pesticides are commonly used in agricultural production. Research shows that pesticides have negative impacts on health and wellness. As more research is conducted and published, specifically on the impact of pesticide inhalation, pesticide testing will continue to develop in the cannabis industry. We ensure our pesticide testing is accurate and legally defensible by utilizing two separate instruments, GC-MS MS and LC-MS MS to perform a pesticide test. This gives our clients and consumers peace of mind.
Homogeneity is the quality in which an item has uniform structure or composition. Homogeneity testing is found within multiple industries, including the cannabis industry. The process of ensuring a product or item is homogeneous begins with sampling and continues throughout the testing process. Homogeneity testing is required in Oregon.
Green Leaf Lab is a valuable resource for product development. With years of cannabis testing experience, combined with nutraceutical and pharmaceutical product development experience, we continually push the industry forward by providing consulting on product development and production practices. This ensures cannabis goods are manufactured accurately and consistently. We have worked closely with many of the leading brands you trust in cannabis goods. Our expertise ensures the successful development of new products and a competitive advantage for our clients.
The representative sampling of cannabis and cannabis products is the first step to ensure accurate test results and therefore the accurate labeling of those goods. If the sample collected does not properly reflect the entire batch of cannabis or cannabis goods, the test results will not be representative and therefore inaccurate. This can create issues for both cannabis businesses and consumers alike. At Green Leaf Lab we pride ourselves on going above and beyond to ensure batches are sampled following a comprehensive sampling protocol to ensure accurate results and defensible data.
Residual solvents are organic volatile chemicals used in the manufacturing or extraction process. In cannabis, they are used to extract cannabinoids or terpenes from the plant material. These solvents are often not completely removed by practical manufacturing or extraction processes. Therefore, testing for these chemicals is required in many industries, including cannabis.
Heavy metals are contaminants that originate from both manufacturing and soil contamination in agricultural production. Most consumer products intended for human use and sold in regulated markets are required to undergo heavy metals analysis in order to protect consumer safety. California requires all cannabis products undergo testing for Cadmium, Lead, Arsenic, and Mercury.
Microbiology is the study and analysis of microorganisms. As with many agricultural or manufactured consumer goods, contamination can occur with improper handling or production techniques. Exposure to these harmful microbiological contaminants can pose serious health risks. Microbiological testing ensures safe product reaches consumers, especially those with compromised immune systems. In California, cannabis must be tested for Salmonella, E.coli, Aspergillus species A. fumigatus, A. flavus, A. niger, and A. terreus.
Mycotoxins are toxic metabolic products from molds or fungi and are typically found in agricultural products. Mycotoxins can negatively impact health, most notably for the kidney, liver, and endocrine systems. In California, cannabis products intended to be consumed via inhalation are required to be tested for Mycotoxins. The total presence of Aflatoxin B1, B2, G1, G2 cannot exceed 20 ug/kg, and total Ochratoxin A cannot exceed 20 ug/kg.
Water activity is the analysis of the binding of water molecules in agricultural or food items. It is a measurement of the availability of water that is utilized for microbial growth. Water activity below established thresholds will prevent microbial growth from occurring.
Vitamin E Acetate
Vitamin E Acetate is a synthetic variant of Vitamin E and is often used in topical products such as skin creams or medications. Vitamin E Acetate is a fat-soluble liquid when kept at room temperature and therefore has been used as a thickening agent for some THC vape cartridge manufacturers. Having your product tested to ensure your product is free from Vitamin E acetate will bring you and consumers peace of mind.
Foreign materials are items that are typically unwanted in the production of food or products, such as stems, insects, sand, dirt or other unwanted fragments. Foreign materials typically found in cannabis are dirt, sand, insects or soil. California requires laboratories to perform foreign material inspections that must not exceed acceptable limits.
Moisture content is the amount of water in a sample, measured by weight. This is an important indicator for the likelihood of microbial growth as well as the curing technique for cannabis flower. Some claim that moisture content affects the smooth or harsh experience when inhaling cannabis.
