Labels contain very vital information about their products; the brand, type, composition, expiration dates, production dates, regulating body certifications, and so on. Any product can be produced and claim it is suitable for use, but until a guarantee is seen on the label in the form of test results or approval, the claim means nothing.

Test results are one of the most important contents of labels on products from online dispensaries in Canada. These results provide you with proof that the product you are about to purchase has been tested by a third-party lab independent of the manufacturer. Although this information could be limited depending on the regions labeling laws, some producers publish results on their labels.

Any product which has no means of access to its lab test results is a red flag. It is either the product has not undergone the test, or there’s a reason why the producer has refused to make it visible. However, it is important to know that not all lab tests are accurate, and testing standards differ across the industry. Should you decide to buy weed online or its products, below are why it is essential to read the label’s test result.

Note that the types of tests performed on different products depending on their intended use, product type, and relevant regulations.


Most test results will at least show the intensityof CBD, THC, and some other cannabinoids available in the product. While the THC and CBD are the most recognized, others are important, such as THCa, CBN, THCV, CBDa, CBG, and CBC. These cannabinoids are responsible for the physiological and psychological effects of various products.


Compared to the cannabinoids, terpenes are less commonly shown in the test results. Terpene is more of what gives the flavor and the aroma of weed products. Tests for terpenes are intentionally absent on some products and are generally important on some others.

Common terpenes you may find their results include myrcene, terpinolene, and limonene.

Residual Solvents

Due to some cannabis production methods, there can be a solvent level behind the product. Some of these materials could potentially cause harm to health if their level is quite high.  However, depending on the region, the standard for acceptable levels for these solvents differs. Some of these solvents usually tested for and shown on results include xylenes, benzenes, butane, and propane.

Moisture Content

Some product’s Certificates of analysis will include the moisture content level of the test sample. Generally, if the moisture content is above 15% (too high), there is a high risk of fungi and bacteria infesting the product. On the other hand, if it is below 5% (too low), the product could be dry and brittle, resulting in a harsh consumption experience.

Other Safety Tests

Another significant test usually carried out is the microbial test for microorganisms like yeast, mold, E. coli, and salmonella to ensure the products meet standard and is safe for use. Another is the heavy metal test in the Certificate of analysis for highly toxic heavy metals. These metals cannot be efficiently removed by human anti-bodies and could cause damage to humans. They include arsenic, lead, cadmium, and mercury.

Now you know why you should read labels when you are about to get a product. They contain so much about the product’s purity, edibility, and authenticity. If you buy weed online or its products and cannot access the label or test results, please you might need to question its authenticity.
