Why is Cannabis Testing Important?

Health Canada has not formally provided the requirements for uniformly standardized testing of cannabis products. Understanding the content of various cannabis products is vital for the consumer. That is why most reputable producers are relying on third-party laboratories to verify their products efficacy. Synfine Research lab is a privately owned independent testing lab with more than thirty years' experience in analytical testing. Synfine is not affiliated with any licensed cannabis producers, consumers or brands, and has no vested interest in the outcome, and can provide independent trusted testing to both the producer and consumer. Through the use of sophisticated analytical equipment and established methods, Synfine's PhD's can provide the required testing to ensure, identify and satisfy the safety of the cannabis products as per Health Canada ACMPR guidelines.

Cannabinoid Analysis/Potency

Potency analysis is the process of identifying and quantifying cannabinoids in cannabis and its related products. Knowing the concentration of a product is essential for consumers interested in knowing the exact amounts of cannabinoids in their product. Potency analysis, consists of measuring the amounts of specific cannabinoids present in a product, such as THC, THCA, CBD, CBDA, and CBN. Cannabinoid profiling is an important tool in allowing consumers to make smart and informed decisions on which products will provide the desired result for both research and diagnostics. Some may require products with high levels of THCA while others need products high in CBD and low in THC. Potency testing is especially important for infused products (taken orally), which may take an hour experience the pharmacological effects of the product. Potency analysis is generally performed with either Gas Chromatograph (GC) or and High Pressure Liquid Chromatograph (HPLC)

Synfine Research tests for the following cannabinoids in standard potency testing:

  1. THCA - Tetrahydrocannabinol Acid
  2. d9 - THC("THC"-Delta-9-Tetrahydrocannabinol
  3. CBD - Cannabidiol

  3. CBGA - Cannabigerol Acid
  4. CBL - Cannabicyclol
  5. d8 - THC-Delta-8-Tetrahydrocannabinol
  6. THCV- Tetrahydrocannabivarin


Terpene Testing

Terpenes and terpenoids are the primary building block of plant resins or "essential oils" and contribute to the scent, flavor, colors and related pharmacological activity. Knowing the terpene content can help a consumer choose a product to match the desired effect. Synfine can identify 22 different terpene compounds using a gas chromatograph equipped with a flame ionization detector (FID).

Residual Solvents Testing

Solvents are often used in the extraction of cannabinoids and terpenoids from plant material, varying from CO2 to more dangerous chemicals. If a concentrate is prepared by chemical extraction (by using butane, for example), residual solvents may exist in the final product. Repeated exposure to residual solvents may result in health issues to consumers, including allergic reactions, headaches, nausea and more. By measuring the amounts of solvent in a cannabis concentrate, we are able to provide growers and manufacturers with the information they need to adjust their process and ensure that the highest quality of concentrates are being produced. Residual solvents are analyzed with a Gas Chromatograph with an FID detector and a headspace auto-sampler.

Pesticide Residue Testing

The presence of pesticides in a cannabis product indicates that pesticides were used when growing the cannabis or those pesticides have contaminated the flower or final product after growing. The presence of pesticides indicates a problem for the licensed producer and the inability to offer that product for sale. Synfine test for all 95 compounds on Health Canada's December 2017 Mandatory List Pesticide. Qualification and quantification can be performed with mass spectrometers, which are the most sensitive at detecting pesticides.

Microbial Screening

All natural products contain varying amounts of naturally occurring micro-flora. Quantifying the amounts of mycotoxin can help producers identify product issues before they are sold to the public. Synfine’s microbial screens quantify Total Viable Aerobic Bacteria, Total Viable Yeasts and Molds, and Total Viable Coliforms (including E. coli). Synfine Research uses polymerase chain reactions (PCR) to screen for the presence or absence of Salmonella spp. and possible Shiga toxin-producing strains of E.coli. Shiga toxin producing E. coli (STEC) and Salmonella spp. are considered opportunistic pathogens and carry a strict zero-tolerance policy in food samples. Mycotoxin & contaminant testing is a standard test utilizing High Performance Liquid Chromatograph (HPLC) with a Fluorescence Detector and a Post Column Reactor.

Microbial Testing Services

We offer a number of services to screen for bacterial and fungal contaminations in Cannabis and Cannabis infused products including:
  1. Yeasts and Molds
  2. E. coli and Coliforms
  3. Salmonella
  4. Aerobic Bacteria
  5. Cladosporium*
  1. Alternaria
  2. Botrytis
  3. Mucor
  4. Penicillium*
  5. Aspergillus*
* Mycotoxin producing fungi common to Cannabis

Heavy Metals Screening

The presence of pollutant heavy metals such as lead (Pb), mercury (Hg), arsenic (As), & cadmium (Cd) is common in cannabis products. The sources of these contaminants are soil, water, and air. ICP/MS and AA Spectrophotometers have been reliable sources of instrumentation to test for heavy metals. The significance in testing for metals, such as lead, mercury, cadmium, and arsenic is imperative and required by Health Canada. Reducing the exposure to these heavy metals will reduce the risk of possible poisoning. Synfine Research tests heavy metals in cannabis with utmost accuracy to ensure a safe product.

Moisture Content

Moisture content is a measurement of the concentration of water in a sample. In the event of too much water the product will have a higher susceptibility to microorganisms. The moisture content of properly dried and cured Cannabis should be approximately 15%. The water activity measurement should be below 0.65aw to protect against spoilage during storage.

Sample Submission

1. Send completed form for approval and ship your sample(s) to: 120 Newkirk Road, Unit 19, Richmond Hill, Ontario, L4C 9S7, Canada
2. Once the package has been received, an email will be sent indication we have received the sample(s), along with a date that results are expected.

Recommended Method of Sampling Cannabis Flower

The potency of cannabis can vary dramatically within a batch of cannabis flower (i.e. from bud to bud) and so the quality of testing results depends largely on good sampling methodology. To reduce the potential effect of variability it is necessary to ensure that the composition of a test sample is representative of the larger batch of cannabis. Synfine Research suggests the following best-practice procedure to use when preparing a sample for testing:
- If the batch is stored in multiple containers (e.g, buckets, totes, or bags), take one bud (1-2 g) from each container that makes up the batch, taking care to pick from the upper, middle, and lower sections of the different containers. If the batch is all in one container, take multiple one-bud samples from the upper, middle and lower sections of the container.
- The suggested minimal sample mass required for potency testing is ~0.2% of the batch size. For example, a 5 kg (11 lbs) batch would need a sample of at least 10 g. Prepare the final test sample by combining all samples taken from step 1, then label and submit to Synfine Research for analysis.
- In general, 60 g samples of dried bud are necessary for the full suite of ACMPR required tests, but this may vary depending on your specific needs.

Cannabis Extracts /Oils


As cannabis extracts and oils are typically homogeneous, a smaller sample size of approximately 5 g is necessary for most of the required tests, but 25 g is still required for European Pharmacopoeia compendia Salmonella testing. In general, 30 g samples of oils/extracts are required for the full suite of ACMPR required tests.
