New Hampshire cannabis testing overview
New Hampshire's Therapeutic Cannabis Program dates to 2013 and operates a small non-profit Alternative Treatment Center model with limited commercial scale. All cannabis products sold in New Hampshire must be tested for potency, contaminants, microbials, and (for concentrates) residual solvents by a lab licensed under NH DHHS - Therapeutic Cannabis Program. Look for ISO/IEC 17025 accreditation and currently valid state licensure when choosing a lab.
Frequently Asked Questions
How many cannabis testing labs are in New Hampshire?+
We are still building our New Hampshire testing lab directory. Cannabis testing in New Hampshire is regulated by NH DHHS - Therapeutic Cannabis Program. If you know of a licensed lab that should be listed, please submit it.
What tests are required for cannabis products sold in New Hampshire?+
New Hampshire 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. NH DHHS - Therapeutic Cannabis Program 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 NH panel.
How much does cannabis testing cost in New Hampshire?+
Full-panel compliance testing in New Hampshire 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.
What accreditations should a New Hampshire cannabis lab have?+
At minimum, look for ISO/IEC 17025 accreditation from a recognized body (A2LA, PJLA, ANAB, or similar). New Hampshire may also require specific state-level certification or licensing from NH DHHS - Therapeutic Cannabis Program. 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.
What is the typical cannabis testing turnaround time in New Hampshire?+
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.
How do I read a cannabis Certificate of Analysis (COA)?+
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.
