Every assay a compliance panel might ask for, and which labs run it.
01 · Potency
171 labs
Cannabinoid Potency
Quantifies THC, CBD and minor cannabinoids. Required on every compliance panel and on the label of any product sold at retail.
90% OF INDEX
02 · Terpenes
167 labs
Terpene Profile
Identifies and quantifies the aromatic compounds that drive strain character. Usually optional for compliance, but a major marketing input.
88% OF INDEX
03 · Pesticides
168 labs
Pesticide Residue
Screens for regulated pesticide residues at parts-per-billion levels. A failure here is the most common cause of a batch being destroyed.
88% OF INDEX
04 · Mycotoxins
148 labs
Mycotoxins
Detects aflatoxins and ochratoxin A produced by mould. Mandatory in most regulated markets because the toxins survive processing.
78% OF INDEX
05 · Heavy metals
158 labs
Heavy Metals
Measures lead, arsenic, cadmium and mercury. Cannabis is a hyperaccumulator, so contaminated soil shows up in the finished product.
83% OF INDEX
06 · Microbials
169 labs
Microbial Contaminants
Screens for total yeast and mould, coliforms, E. coli, salmonella and Aspergillus species. Required before any product reaches a patient.
89% OF INDEX
07 · Residual solvents
159 labs
Residual Solvents
Confirms that butane, ethanol, propane and other extraction solvents have been purged below action limits. Applies to concentrates and vapes.
84% OF INDEX
08 · Moisture / Aw
116 labs
Moisture & Water Activity
Water activity above roughly 0.65 Aw lets mould grow in the package. Cheap to run and the single best predictor of shelf-life failure.
61% OF INDEX
09 · Stability
36 labs
Stability & Shelf Life
Repeat testing across a storage window to establish an expiry date and prove potency claims hold over time.

Cannabis Lab 101: Sampling and Why the Sample Matters More Than the Instrument
I've watched a perfectly calibrated instrument return a useless result because the sample going into it was wrong. This article covers increment counts, batch-size rules in California, New York, Michigan, and Minnesota, chain-of-custody requirements, and the lab-shopping problem that undermines all of it.

Cannabis Lab 101: Pesticide Testing (LC-MS/MS vs GC-MS/MS) and Why You Need Both
I spent years running pesticide panels on cannabis flower and learned fast that no single instrument platform covers the full analyte list. This guide walks through QuEChERS extraction, matrix effects, why GC-MS/MS handles what LC-MS/MS cannot, and what California's §15719 actually requires your LOQ to be.

Cannabis Lab 101: Stability Testing, Expiry Dates, and How Labs Set a Shelf Life
I spent years running compliance panels and watched stability testing get treated as an afterthought. This article breaks down real-time vs accelerated studies, what states actually require, how THC degrades over time, and what acceptance criteria your data must hit before a regulator will approve an expiration date.
