Unraveling Lab Reports for CBD Products

You’ll hear us say time and again that you should only purchase lab tested CBD products. In a 2017 study, The Journal of the American Medical Association found that as much as 70% of the CBD labels they tested were inaccurate. One way to protect yourself as a consumer is through lab results. But what does that mean? We’re here to help with this article on unraveling lab reports for CBD products.

What is a Lab Report?

Hemp is an industry that is sadly lacking in regulation. Manufacturers do not follow one set of standards for product packaging, labeling, or even serving sizes. Because of the lack of production standards, some hemp based products can be confusing to buy and consume. One way to make sure that you’re purchasing a safe, quality, product is to verify that there are lab reports made available to you.

Are There Differences?

Just as you’ll see differences in hemp products from manufacturer to manufacturer, you’ll see differences in lab reports. Some manufacturers make multi page documents available to you while others provide a quick summary. These will vary both by lab and by product.

Why Do I Care?

Hemp is a porous plant. If it’s planted in unhealthy soil, it will soak up those contaminants and possibly end up in your box or bottle. Additionally, you want to make sure that the active ingredients (CBD or other cannabinoids) that are in the package match the label. If they don’t, you could be taking a much different serving than you think you are. Essentially, the goal is to make sure that everything you want in your hemp product is there – and everything you don’t want (like those contaminants or even THC) are not present.

Lab Reports versus Certificates of Analysis

The phrase “lab report” or “lab test” may be used interchangeable with “certificate of analysis” (COA). In reality, though, the lab report is the full document and the COA is the shorter document that certifies those results (essentially the cliff notes version.) Often the COA is all that is made available to the public.

Why are Lab Reports Important for CBD Products?

Cannabinoid Content

There are more than 100 compounds, or cannabinoids, found in hemp plants. Those compounds make up the cannabinoid content. If you’re taking a tincture with 300mg of CBD and 0 THC on the label, the cannabinoid content is what you’re looking at to make sure that you’re getting what you paid for and also that you’re not taking more THC than you bargained for. A high THC hemp product is referred to as “hot” and they are definitely out there.

Contaminants Testing

When we’re talking about hemp, contaminants fall into the categories of pesticides, heavy metals, solvents and microbials. Pesticides used to grow the hemp, or microbials (bugs) that made it into the hemp stalks can leach into the soil and your bottle. Heavy metals from bad soil can also make it through, as can solvents if the hemp oil is not extracted safely. Each state has different allowable limits.

How Do I Read a Report?

Let’s start with definitions of all of the jargon that you’ll see on your report.

Just for the Math of It

The first thing that you’ll see on the lab report is usually that cannabinoid profile – how much of each compound was present in the sample tested. Do keep in mind that a test is just that – a sample. Using our gummy example able, the sample size was 5 gummies. Enough that they feel it to be a good representative of the whole. Any good lab will require at least double the amount that they need to test in case they see inconsistencies and want to re-test.

Some labs will quote in milligrams and others will quote in percentages. In this example, this is a 50mg strength soft gel capsule. The results column tells you that the test results came to 60.18 mg and how those broke down. There were 52.62mg of CBD and trace amounts of CBN, CBG, CBDV, CBC and THCV.

Cannabinoid Profile Example

This COA quotes in terms of percentages as well as ml, and it gives a quick chart on the other items tested, such as those pesticides and heavy metals. This is a lab test for a lotion, so they cannot provides results per serving. That’s where our math comes in. The CBD potency will reflect mg/g – concentration of cannabinoids per gram of product. You may also see mg/ml if measuring a liquid in milliliters. One gram and one milliliter are equal. They’re quoting 543.2 milligrams of cannabinoids in 30 ml (1 ounce.) We multiply that by 2 because this is a two ounce jar for a total of 1086.4 cannabinoids in this lot. The label states 1000mg.Lab Test Key

 

Here’s another lab example that does the math for you and tells you the stated label quantity.

If the product label states 0 THC, that’s something to check as well. While it’s not likely to fail a drug test from taking a full spectrum CBD product, it can happen. If your career is at risk or you want to avoid THC for other reasons, make sure to check the COA.

Solvents, Pesticides and Microbials – Oh My

When looking at Lab Report for these dirty possibilities, it’s a simpler task. This is where we want to see those LOQ, LOD and ND notations to tell us that they are not present. Lab reports will often tell you what that quantitative limit is, as well.
