Cannabinoid Profile

A complete cannabinoid profile will help a patient determine the potency and medicinal benefits provided by their cannabis. PSI Labs can accurately test for the major cannabinoids (THC, CBD and CBN), as well as many of the minor cannabinoids (THCV, CBG, CBC, THCA and CBDA).

What are Cannabinoids?

The endocannabinoid system is a crucial physiologic system necessary for establishing and maintaining human health. Endocannabinoids and their receptors cover the entire body. Phytocannabinoids (cannabinoids found in cannabis, and other plants) stimulate the body’s cannabinoid receptors, and affect the mind and body in a number of different ways. They are among the active ingredients that contribute many of the medicinal properties of cannabis.

Terpene Profile

A more informed cannabis patient or cultivator may be interested in the unique terpene profile of different medicines and its relation to the flavors and effects of the particular strain of cannabis. PSI Labs’ state of the art GC/MS is fully equipped to run full terpene profiles to accurately test for terpenes including, but not limited to Limonene, α-Pinene, β-Pinene, β-Myrcene, β-Caryophyllene and Linalool.

What are Terpenes?

Terpenes are the chemical compounds responsible for giving cannabis its flavor and unique aroma. Like cannabinoids, research has shown that terpenoids have medicinal properties. The synergistic combination of terpenes and cannabinoids create an “entourage effect,” meaning that use of the entire plant is more medically beneficial than any one cannabinoid or terpene in isolation.

Residual Solvent and Chemical Residue Screening

Cannabis-infused products constitute an ever-growing portion of the retail cannabis marketplace. Patients who use concentrates and extracts must be able to know that their medicine is safe, and free from residual solvents. Volatile chemicals like naphtha, butane, propane and hexane are examples of solvents used in the chemical extraction process. If an extraction is not expertly carried out, residual solvents may remain in a patient’s medicine.

Using a headspace sampler paired with a mass spectrometer, PSI Labs can accurately detect trace levels of volatile compounds used in various extraction methods.

Consultation Services

PSI Labs is in the unique position to offer specialized scientific consultation services. Depending on our clients’ needs, we can provide a broad range of consultation services. Consultation services may range from preventing pestilence in the initial grow phase, streamlining edible production (accurately marking and measuring doses of activated THC in cannabis-infused products), determing cannabinoid ratios in clones, to specialized breeder services.

Prices for Consultation Services will vary depending upon clients needs.

Visual Inspection Utilizing Microscope with Imaging System

PSI Labs will visually screen for pests and obvious mold infestations as part of our rigorous sample documentation procedure. PSI Labs will also provide attractive, high-magnification images for clients to use in advertising/cataloging.

Visual inspection and imaging is an included service as part of our regular service offerings.

Plate Enumeration (Microbiological Examination)

As with residual solvent and pesticide residue analyses, a microbiological examination is a crucial component of a full safety compliance screen. Cannabis is vulnerable to fungi and bacterial diseases; its growing conditions are often ideal environments for microbial growth.

PSI Labs uses plate enumeration to accurately determine the total amount of microbiological contamination present on a sample of cannabis. A “passing” microbiological examination verifies the sample is safe for human consumption. As opposed to microscopy or visual analysis, plate enumeration will quantify the amount of contamination in a sample (e.g. 30,000 Colony Forming Units [CFU] per gram).

Pesticide Residue Analysis**

An area often overlooked by the medical cannabis community, cannabis may contain pesticide residues in significant amounts. Due to the extraction process, cannabis-infused products may contain even higher amounts. In order to accurately screen for pesticide residue, PSI Labs will isolate, separate, identify, and quantify a large number of chemical compounds at extremely low concentrations.

** While not part of our current service offerings, PSI Labs is currently in method development and plans offer Pesticide Residue analysis in the coming months.
