Cannabis Testing: Importance of Data Quality

December 28, 2021

The cannabis industry has witnessed tremendous growth in the recent past. And if recent projections by multiple research bodies are anything to go by, then the industry is headed for better times. 

As marijuana continues to garner mainstream interest, there’s a corresponding increase in the demand for testing. 

But what is cannabis testing, and why does data quality matter? Those questions shall be the focus of this article.

Choosing the Best Cannabis Products

Several factors go into determining the quality of cannabis goods. Notable ones include the extraction method used, seller reputation, and proof of lab-testing. 

First: Choosing Cannabis Products by Extraction Method

There are several ways to obtain various cannabis extracts from raw plant materials. However, marijuana experts generally recommend the Carbon Dioxide (CO2) Extraction Method, also known as Supercritical CO2 Extraction. 

The Supercritical CO2 Extraction Method delivers purer and more potent cannabis compounds than other common extraction methods, such as Solvent Extraction. 

So, one way to vouch for the quality of marijuana-infused goods is to check whether the specific cannabis compounds in the product were obtained by CO2 Extraction.

Second: Choosing Cannabis Products by Brand Reputation

The cannabis industry is fairly lucrative. That explains the ever-growing number of investors setting up marijuana ventures. 

Unfortunately, the cannabis market isn’t free from unscrupulous sellers swindling unsuspecting buyers. One way to overcome marijuana scams is by purchasing your weed products from established brands. 

When you choose high supplies or other reputable cannabis suppliers, you’re assured of getting your hands on premium-quality products at industry-competitive rates.

Third: Choosing Cannabis Products by Proof of Lab Testing

This is arguably the most important consideration while shopping for marijuana goods. 

As you browse the e-commerce websites of reputable cannabis sellers, you’ll realize that each product comes with proof of lab-testing. It’s important to take your time going through the information presented in these reports. 

More importantly, beware of cannabis suppliers who don’t offer proof of lab testing.

Understanding Cannabis Testing

Cannabis testing mainly screens for the presence of cannabinoids in a weed-based product. Cannabinoids refer to the pharmacologically beneficial compounds that occur naturally in the cannabis plant. 

So far, researchers have uncovered at least 120 cannabinoids. The most common ones include cannabidiol (CBD) and tetrahydrocannabinol (THC). 

Cannabidiol and tetrahydrocannabinol are also the most abundant cannabinoids. The two compounds account for a whopping 40% of the total extracts obtained from cannabis plant materials. 

Since CBD and THC are the most abundant compounds in marijuana, most cannabis testing organizations focus on these two compounds. 

However, marijuana screening may also target other fairly uncommon cannabinoids like cannabigerol (CBG), cannabinol (CBN), and cannabichromene (CBC). Depending on how intricate the screening process is, the reports could also indicate the presence of terpenes. 

Terpenes are compounds that give marijuana cannabinoids their distinctive taste and aroma. Common ones include pinene, linalool, and limonene. 

The following are reasons to insist on lab-tested cannabis products;

1. Cannabis Testing Confirms the Ingredients in the Product Label

This is the most significant role played by cannabis screening. 

The testing reports prove that the ingredients appearing on the product label are actually contained in the product. Therefore, you know you’re buying the real thing. 

Without proof of lab testing, you may never know whether the product you’re about to purchase is marijuana in the first place. It might as well be a random concoction of herbal extracts marketed as a weed.

2. Cannabis Testing Reveals the Potency of Cannabinoids 

Marijuana products come in varying concentrations of cannabidiol and tetrahydrocannabinol. These concentrations are also known as potencies or strengths. 

It’s important to understand the strength of CBD and THC in cannabis goods before purchasing the product. For instance, tropicana strain is energizing but also helps in relaxation. That’s mainly because the potency of these compounds is a crucial factor when determining your doses. 

Admittedly, marijuana has no standard dose for everyone. But all factors held constant. Higher potency of CBD and THC translates to lower servings. 

The data on potency provided by lab testing reports is vital for tetrahydrocannabinol. THC is the compound in marijuana that induces a “high.” Therefore, you want to ensure you’re consuming the right amount of tetrahydrocannabinol based on your tolerance and sensitivity to the compound. 

3. Cannabis Testing Reveals the Presence of Terpenes 

Besides cluing you in on the potency of cannabinoids, cannabis testing reports also offer more insights into the presence of terpenes in a product. 

Remember, the overall taste and aroma of a cannabis good mainly depend on the dominant terpenes in the product. 

Also, some terpenes may enhance the overall therapeutic effects of cannabinoids. That’s all the more reason to familiarize yourself with the presence of these compounds in a weed-based product. 

4. Cannabis Testing Confirms Product Safety

Cannabis screening not only confirms that a product contains the ingredients appearing on the label. These tests also certify that those compounds are safe for consumption. 

Note that cannabis goods not only include cannabinoids and terpenes. These products may also contain preservatives, penetration enhancers, artificial sweeteners, etc. Marijuana screening reveals the safety of these compounds. 

Cannabis tests may also establish the presence of toxins, including residual solvents like butane, microbial contaminants like salmonella, and heavy metals like lead.


There's a rising demand for cannabis testing as mainstream interest in marijuana continues to grow. There are numerous benefits of investing in lab-tested cannabis goods. Most importantly, it’s vital to insist on products screened by accredited and independent laboratories instead of testing organizations affiliated with a manufacturer or retailer. Moreover, For products containing cannabis derivatives, rigorous testing is necessary to ensure
