The Importance of Testing Cannabis

Chem Service Cannabis Testing

Greyhound Chromatography is pleased to represent the worlds leading manufcturers in providing Reference Standards and Materials, Columns, UHPLC/HPLC Solvents and Reagents (including Derivitization Reagents) specifically for testing Cannabis for medicinal purposes. Please visit our home page for an overview of the products that can be provided.

With increasing regulation worldwide to ensure that medicinal cannabis is free from inpurities there is a need for stringent testing for Cannabinoids, Residual Solvents, Terpenes, Pesticides, Trace and Heavy Metals and other impurities that may be present in the soil or growing medium, additives to encourage healthy growth and water. To date there are over 23 states in the U.S., Canada and countries within Europe with differing laws allowing the use of Cannabis for medicinal or recreational use. The debate about cultivating cannabis for medicinal vs recreational use is complex, there is a wealth of information available via the internet. Greyhound supplies all the consumables needed for the analysis of cannabis using chromatography, products are added daily to the portfolio of products that can be used during the testing process, if you require a specific product and do not see it listed on our website please email sales@greyhoundchrom.com we will be happy to source specific products for you.

Cannabis can have many benefits and as it becomes more legalized across the United States and many countries around the world, the industry is starting to be held to quality control standards. Like any growing industry though, there is still a lot of room for growth regarding safety and testing. For example, if medical cannabis was put into the same bucket as other pharmaceuticals, every batch would be tested for potency and purity, but that is not always the case.

During the cannabis extraction process to create concentrations for recreation, food, pharmaceuticals and personal care items, solvents and other hydrocarbons can be used that contain potentially unsafe residues. Testing cannabis for both medical and recreational use varies from state to state, but it is important to test for residual solvents that can be potentially harmful to users.

What are the Active Chemicals in Cannabis?

Cannabis is derived from a complex plant called hemp, or Cannabis sativa. The most known active ingredient is THC, or delta-9-tetrahydrocannadinol, that is found in the leaves and flowering parts of the plant and is responsible for the behavioral influences of marijuana. The other common active ingredient is cannabidiol which is related to diet, energy utilization and pain sensors. The structure of the chemicals are very similar, but their effects are quite different.

What are Cannabis Oil Solvents?

When utilizing a solvent to extract cannabis oil it is intended to evaporate, but sometimes the evaporation process does not remove all of the solvent and it remains in the final product. Solvents are separated into 3 categories: Class 1 (volatile solvents to avoid), Class 2 (suspect solvents to limit) and Class 3 (safe solvents to use).

Some common residual solvents to test for include:

Acetone (Class 3)	Heptane (Class 3)
Acetonitrile (Class 2)	Methanol (Class 2)
Benzene (Class 1)	Pentane (Class 3)
Chloroform (Class 2)	Toluene (Class 2)
Ethanol (Class 3)	Triethylamine (Class 1)

Can you Make Cannabis Oil Without Solvents?

There are many ways to make cannabis oil without the use of harmful solvents. A solventless, or mechanical extraction, can be used and does not require chemicals to achieve the final product. When small hair-like growths (trichomes) are rubbed or pressed from the plant, it results in a concentrate known as kief. Ice water extraction can also be using to make kief which is then pressed into bubble hash. These processes leave more of the original cannabinoids intact that are normally altered from the use of solvents and can be tried safely at home.

What is a Cannabinoid Profile?

Cannabinoids are chemical compounds produced by cannabis flowers that mimic the effects of endocannabinoids. These chemicals are naturally produced in the human body to help us maintain homeostasis.

A cannabinoid profile informs consumers about the concentration of active cannabinoids in their product. Cannabinoids can help with a variety of things such as pain, nausea relief, preventing nervous system degeneration, and reducing seizures and convulsions, so this profile aids processors, physicians and consumers in understanding the potency of cannabis products and when assessing which product is best suited for the patient’s needs.

How do you Test Cannabis Oil?

There are no strong regulations or guidelines currently in place about how cannabis is tested and measured making it even more important to test cannabis at home. To get an accurate determination of solvent residuals in a cannabis sample a chromatography should be used. This test provides high accuracy that users can depend on.

Analyzing Cannabinoids using Chromatography

Chromatography plays a vital role in the purification and testing of cannabis products and can be tightly linked to cannabis safety. This testing process is helpful to accurately measure the levels of cannabinoids and terpenes while also checking for potential contaminants such as pesticides, heavy metals, and residual solvents.

Chem Service Provides Residual Solvents for Testing the Safety of Cannabis

Chem Service has recently launched residual solvents that test the safety of cannabis products. Through our years of experience with chemical testing, we have curated residual solvent mixes for those across the United States and additionally for those who live in California, Oregon, Florida, and Canada.
