Cannabis Testing Data

Every tested package, every lab, every quarter of New Jersey's released testing data. 72,098 packages across 133 facilities, 8 labs, and 3,499 strains. Jan 2023 – Dec 2025.

By Max Jackson — former licensed cannabis cultivator, now reading the same Metrc data he used to generate.

Built on data New Jersey made public. The Cannabis Regulatory Commission released one of the most complete cannabis testing datasets any state has put in the open — every tested package, every lab, every quarter. None of the analysis here would exist without that. Credit where it's due.

Testing & Safety

98.0% of packages pass all required tests. 1,411 packages failed. The leading analyte failures are Total Yeast and Mold (746), Water Activity (255), Total Aerobic Microbial Count (185), and Chromium (140) — three microbial categories plus one heavy metal. 573 packages were flagged remediated. Of these, 570 had no failed test on file in this dataset; 3 had a prior failed test.

Remediation Patterns

573 packages flagged remediated. Of these, 570 had no failed test on file in this dataset; 3 had a prior failed test.

The Metrc RemediatedProduct flag indicates a product designated as remediated. Two interpretations are consistent with the data: that products underwent a remediation process before testing, or that packages with initial failures were remediated and re-tested. The data alone cannot distinguish between them.

New Jersey has no consumer-facing remediation labeling requirement.

Potency

Median flower Total THC climbed from 20.84% to 26.03% over 12 quarters — a 5.2-point increase. The distribution clusters heavily in the 20–30% range, with 16.67% at the 5th percentile and 30.99% at the 95th.

Flower Total THC Distribution

All flower packages, 2% bins. Median 23.98%, mean 23.93%.

Reference line at 30% reflects the proposed cap in New Jersey A1806 (2026), which would cap flower at 30% Total THC and concentrates at 60%. The bill was introduced after this dataset's cutoff.

Flower Total THC Distribution by Year

Same flower distribution, split by calendar year. Each curve is normalized to its own share of packages so years are comparable — watch the peak shift right over time.

Built by summing each year's quarterly flower distributions (2% bins). The rightward drift in the peak tracks the same upward drift in reported median Total THC shown in the trend chart above.

Where Each Lab Falls on the Total THC Distribution

Density curves per lab overlaid on the market distribution of flower Total THC

A note on reading any single lab's numbers: if any lab in a market were to report higher results, the cultivators most likely to move to it would be those with the lowest potency or the highest failure rates. That kind of migration would pull other labs' averages in the same direction — so a fully compliant lab can look anomalous without doing anything wrong. Lab-level differences here reflect client mix as much as lab conduct. This is a description of a market dynamic, not a claim that any lab has reported inaccurate results.

Median Flower Total THC Over Time

20.84% → 26.03% · flower samples only

The dashed line marks January 2024, when New Jersey's microbial action limit was loosened from 10,000 to 100,000 CFU/g. The Total THC trend is shown across that date.

Labs

8 labs serve New Jersey's cannabis market. Lab-to-lab differences in failure rates and median potency may reflect differences in lab methodology, client mix, or sample characteristics. These data do not isolate the cause.

Lab D's package count ramped from 2024 onward; its sample skews toward later quarters when the market median was already elevated. All-time aggregate medians are not controlled for entry timing — see the quarterly potency chart for time-controlled comparison. This is a descriptive correlation in the data, not a claim that Lab D or its clients misreported results.

Stability Testing

29,973 packages were tested for stability over time across 81 facilities (multiple time points per package). 273 of those packages failed at least one stability test row — a 99.09% package-level pass rate. Of 293 failed test rows, 291 were microbial (yeast and mold, aerobic microbial, coliforms, salmonella) and 2 were heavy metal (chromium). 52 facilities have no stability testing on record.

Frequently Asked Questions

Direct answers to the questions this dataset uniquely answers, drawn from the public record.

What is the cannabis testing failure rate in New Jersey?

New Jersey's regulated cannabis passes compliance testing 98.0% of the time. From January 2023 through December 2025, 1,411 of 72,098 tested packages failed at least one test — roughly 1 in 50 batches. The single most common failure is microbial: total yeast and mold.

How high is THC in New Jersey cannabis?

Median flower Total THC in New Jersey rose from 20.84% to 26.03% over three years (January 2023 to December 2025). Most flower clusters in the 20–30% range; the 5th percentile sits at 16.67% and the 95th at 30.99%. This is the upward drift in reported numbers — a description of the trend, not a claim about any lab's accuracy.

How many cannabis cultivators and labs are in New Jersey?

133 facilities have submitted testing data to date, served by 8 testing labs. As of the most recent quarter, 118 facilities were actively testing; 15 have gone dark, meaning no testing on record for two or more quarters.

Why do New Jersey cannabis labs report different THC and failure rates?

Lab-level failure rates differ by more than fourfold under the same state regulation. Those differences may reflect lab methodology, client mix, or sample characteristics. The data shows the divergence but does not isolate the cause — it is not, and should not be read as, evidence that any lab acted improperly.

Is New Jersey cannabis testing data public?

Yes. The NJ Cannabis Regulatory Commission released its full Metrc testing dataset in March 2026 — one of the most complete records any state has put in the open. This dashboard analyzes 72,098 packages drawn directly from those public records.

What is the most common reason cannabis fails testing in New Jersey?

Microbial contamination. The leading individual failures are total yeast and mold (746), water activity (255), and total aerobic microbial count (185) — three of the top four causes are microbial.
