Cannabis Testing Labs in Massachusetts

There are 16 licensed cannabis testing laboratories in Massachusetts listed on CannaBizGuide. All labs are regulated by Cannabis Control Commission (CCC) and data is sourced from Cannabis Control Commission. The number of licensed labs can change as new facilities receive accreditation or existing labs lose their license.

Massachusetts cannabis products must typically be tested for cannabinoid potency (THC, THC-A, CBD, CBD-A and often other cannabinoids), terpene profile (sometimes optional), pesticides, heavy metals, residual solvents (for concentrates), microbial contaminants, mycotoxins, and moisture content. Cannabis Control Commission (CCC) sets the specific analyte panels and action limits. Retest rules, homogeneity sampling, and label claim tolerances are also state-specific. See our testing requirements by state guide for the current MA panel.

Full-panel compliance testing in Massachusetts typically ranges from a few hundred to over a thousand dollars per sample depending on matrix type (flower vs concentrate vs edible), panel scope, and turnaround. Bulk pricing and volume discounts are common for multi-state operators. R&D testing (not for compliance) is usually less expensive. Get quotes from multiple labs and confirm they can test ALL required matrices before committing.

At minimum, look for ISO/IEC 17025 accreditation from a recognized body (A2LA, PJLA, ANAB, or similar). Massachusetts may also require specific state-level certification or licensing from Cannabis Control Commission (CCC). Some operators also look for ORELAP, EMLAP, or TNI certifications, particularly for specific analyte categories. Verify accreditation status directly with the accrediting body - do not rely on lab marketing alone.

Standard compliance testing turnaround is usually 5-10 business days from sample receipt to reported Certificate of Analysis (COA). Rush service (48-72 hours) is available at most labs for a premium. Complex matrices (distillates, edibles with unusual excipients) and retest scenarios often take longer. Plan testing windows into your release schedule, especially around regulated harvest or batch-release deadlines.

A cannabis COA reports pass/fail for each required analyte category plus quantified values (potency % and contaminant levels). Key things to check: batch number, sample intake date, testing methodology references (LC-MS/MS, GC-MS, qPCR), and that the lab's name and accreditation number match a currently-licensed lab. Beware of COAs from unaccredited or out-of-state labs. See our How to Read a Cannabis COA guide for a detailed walkthrough.
