Find your cannabis testing lab here.

You’ve tested your flower in-house using GemmaCert, and the results are excellent; your products are safe, effective, predictable, and compliant.

But there’s still another step before you can bring your product to market: you must send your sample and in-house results or certificate of analysis (COA) to an accredited third-party testing facility.

If you’re new to the cannabis industry, you might wonder, where can I get my cannabis tested?”

First, you’ll need to verify the licensing body (State) where you can test your product. Once you’ve established this, you can then choose a lab that’s right for you.

We’ve pulled together a list of accredited cannabis testing facilities and DEA registered hemp/CBD testing labs to help you take that next step towards compliance. If you’re an accredited cannabis testing laboratory and would like us to include your lab in this directory, please contact us at here

Frequently Asked Questions

1. Why are third-party testing labs necessary?

Testing isn’t just about knowing what’s happening with your plants. You also may need to have an independent third party test your products if you intend to sell them in a medical or recreational cannabis market. Plus, CBD consumers look for third-party tests when they select products. Third-party testing puts the finishing touches on an all-encompassing cannabis analytics regimen that starts at the seed stage.

2. How do I find cannabis testing labs in California?

Luckily for cannabinoid entrepreneurs in the Golden State, third-party testing companies for cannabis are abundant throughout California. Producers in California’s medical and recreational cannabis markets must submit their products to third-party testing before distribution, creating a government mandate for cannabis analytical testing labs to operatea in the state. Due to the intense competition, California cannabis labs generally provide high-quality results.

3. How to start a cannabis testing lab?

Starting a marijuana testing facility will look different depending on the state where you set up shop and the products you intend to test. Each state has different rules for handling and testing cannabis products, and rules also vary significantly for hemp and THC testing labs. Consult with your state’s relevant regulatory authorities to learn the specifics regarding starting a cannabis testing lab.

4. How do I find cannabis testing labs in Canada?

The Canadian government has set strict requirements for companies that want to be certified as cannabis testing labs. Canadian cannabis operators seeking testing for their products are advised to contact the government’s cannabis authority. See our link above for a full list of state-certified cannabis testing labs in Canada.

5. What should I look for in a cannabis testing facility?

The best cannabis testing lab will offer detailed, accurate results for fair prices. When it comes to cannabis testing, though, accuracy is more important than economy. Don’t be tempted to take or offer deals in exchange for fudged numbers. Nepotism is rampant in the third-party cannabis testing industry, so don’t be afraid to put an analytics company on the line to see if it will stay true to its integrity.

6. Are cannabis and hemp CBD lab testing facilities the same?

From a technological perspective, cannabis and hemp lab testing facilities are virtually indistinguishable. From a regulatory perspective, however, cannabis testing labs often have to go through a lot more hoops than their hemp counterparts. Cannabis analytics facilities must receive additional certifications to handle THC-rich cannabis while CBD lab testing facilities often fly under the radar.

7. How do I find cannabis labs in Colorado?

As the epicenter of the American cannabis revolution, Colorado is home to dozens of different reputable cannabis labs. Some Centennial State cannabis labs test all cannabinoid products, others only test CBD. Scroll up for a full list of recommended third-party cannabis labs in Colorado, and don’t be afraid to shop around as you find the right fit for your testing needs.

8. What is the best Florida hemp test laboratory?

10. How do I choose a third-party CBD testing lab?

CBD lab testing is a little bit different from THC lab testing since you can send CBD hemp samples anywhere in the country. As a result, your options are vastly increased when it comes to potential testing labs. In this process, online customer reviews will be your friend, and you may simply want to go with a local lab where you can drop a sample off in person.

11. Are there marijuana testing labs in Massachusetts?

Scroll up to view our list of recommended cannabis testing labs in Oklahoma.

13. How much does CBD testing cost?

Third-party CBD product testing generally costs around $50 – $100 per sample. Testing companies often offer discounts when multiple samples are tested at once—a $100 testing charge, for instance, may go down to $75 when five or more samples are tested and down further to $50 per sample for 10 samples or more. You may also pay a slight premium for working with CBD testing labs that have a reputation for excellence.

14. What are the best hemp testing labs in Tennessee?

Tennessee is home to a handful of reputable cannabis and hemp testing labs. The two Tennessee cannabis testing labs that we would recommend are Kaycha Labs and New Bloom Labs. Out of the two, New Bloom Labs focuses specifically on hemp testing while Kaycha tests both hemp and cannabis. Scroll up for links to the homepages for both facilities.

15. What are DEA hemp testing labs?

Most hemp and cannabis testing labs are certified by the DEA since they test for the presence of an illicit substance: THC. The presence of THC is the main variable both hemp and cannabis labs are testing for, so receiving certification from the federal government’s drug authority is a prerequisite for analytics labs that want to provide the type of data both CBD and THC producers need.
