The Dabwoods Quality Standard
We don’t cut corners. Every gram of hemp extract that leaves our facility has been independently verified by an ISO/IEC 17025-accredited laboratory — no exceptions, no batch skipped.
What We Test Every Batch
Six independent test panels run on every batch before a single cartridge is filled. This is what “lab-tested” actually means.
Cannabinoid Potency
We verify the exact percentage of CBD, Delta-8 THC (where applicable), Delta-9 THC (<0.3% required), CBG, CBN, and the full cannabinoid spectrum. Every label claim is confirmed before products ship.
Pesticide Screening
Over 200 pesticide residues are screened in every batch, including organophosphates, pyrethroids, fungicides, and herbicides. We exceed California Proposition 65 standards — the strictest in the US.
Heavy Metals
Arsenic, cadmium, lead, and mercury — the four heavy metals required by USP standards — are tested in every batch. Hemp is particularly effective at absorbing soil contaminants, which is why testing for this panel is non-negotiable.
Residual Solvents
Our supercritical COâ‚‚ extraction process produces solvent-free oil, but we test anyway. Every batch is screened for over 60 residual solvents including benzene, butane, ethanol, hexane, and propane to USP Class 1, 2, and 3 limits.
Microbial Contamination
Total yeast, mold, aerobic bacteria, bile-tolerant gram-negative bacteria, Salmonella, and E. coli are all tested. Vaping a contaminated product could put that contamination directly into your lungs — which is why this panel is critical.
Mycotoxins
Aflatoxin B1, B2, G1, G2 and Ochratoxin A — naturally occurring fungal toxins that can appear in hemp crops — are screened in every batch. These compounds are known carcinogens at elevated doses and have no place in any hemp product.
From Farm to Cartridge
Every step of our process is documented, audited, and verified. This is what transparent hemp production looks like.
USDA Certified Organic Hemp Sourcing
We partner exclusively with USDA-certified organic hemp farms in Kentucky, Colorado, and Oregon. Farmer relationships are audited annually. All source hemp is tested at harvest before acceptance into our supply chain.
Supercritical COâ‚‚ Extraction
Our SFE (supercritical fluid extraction) system uses COâ‚‚ at precise temperature and pressure to extract the full cannabinoid and terpene profile without residual solvents. The result is a clean, full-spectrum oil that preserves the plant’s natural character.
Pre-Fill Batch Sample Submission
Before any cartridge is filled, a representative sample from each batch is submitted to our accredited third-party lab partner. We do not fill cartridges from batches that have not yet received a passing COA.
COA Review and Batch Release
Our QA team reviews each COA against our internal specifications (which are stricter than the lab’s default limits). Only after written batch release approval does production proceed. Failing batches are quarantined and destroyed.
COA Published on Every Product Page
The batch-specific COA for your exact product is available for download on every product page. You can verify the lab’s accreditation, the test date, all analyte results, and the chain of custody. Transparency is not optional at Dabwoods.
What Is a COA and Why It Matters
Reading Your Dabwoods COA
A Certificate of Analysis (COA) is a document issued by an accredited laboratory confirming the results of testing performed on a specific batch of product. A COA is only meaningful if it comes from a genuinely independent, accredited lab — not an internal test or a paid certification service.
All Dabwoods COAs are issued by ISO/IEC 17025-accredited laboratories that have no financial relationship with Dabwoods other than being paid for testing services. The labs do not know the results we expect. They simply test what we send them and report what they find.
When you download a Dabwoods COA, you can verify:
- The lab’s name and their ISO/IEC 17025 accreditation number
- The batch number matching your product packaging
- The date of testing
- Every analyte tested and its measured concentration
- Pass/fail determination for each regulatory threshold

Everything you need to know about how we test, what we test for, and what the results mean for you.
Full Education Center →In-house testing creates an obvious conflict of interest — a company testing its own products has financial incentive to report passing results. Third-party accredited labs have no relationship with us beyond a testing service agreement. Their accreditation depends on reporting accurate results, not favorable ones. This is the only testing model that genuinely protects consumers.
ISO/IEC 17025 is the international standard that establishes requirements for the competence of testing and calibration laboratories. An accredited lab has been assessed by an independent accreditation body and found to produce technically valid, reliable results. It is the most important qualification to look for when evaluating any product’s third-party testing claims.
Each Dabwoods product includes a batch number on the packaging. This batch number corresponds directly to a COA available on the product page. You can download the COA, find the lab’s accreditation number, and verify that accreditation independently through the relevant accreditation body’s public database (e.g., A2LA, ANAB, or equivalent state body).
Any batch that fails any test panel is quarantined immediately and never released for sale. Depending on the nature of the failure, we investigate the root cause — which can range from a farm-level contamination issue to a processing anomaly. The entire batch is then destroyed under documented conditions. To date, we have never shipped a failing batch.
Vaping any substance carries inherent inhalation risk, and we are transparent about this. Our products use borosilicate glass tanks and ceramic coils to eliminate the risk of heavy metal leaching from hardware. Full-spectrum hemp oil with verified-clean test results eliminates the contaminant risks associated with untested products. We do not add vitamin E acetate or any cutting agents. That said, all vaping is an individual health decision, and we recommend consulting a physician if you have respiratory health concerns.
