Maine, USA hemp laws: quick overview

Maine defines “hemp” in 7 M.R.S. § 2231 (as amended by PL 2019, c. 528 and further by PL 2025, c. 416) as Cannabis sativa L. and derivatives with delta‑9‑THC concentration not more than 0.3% on a dry‑weight basis, or as otherwise defined in federal law ([mainelegislature.org](https://www.mainelegislature.org/legis/bills/bills_129th/chapters/PUBLIC528.asp?utm_source=openai)). The 2025 amendment added definitions for “potentially intoxicating hemp product” and expanded the list of regulated cannabinoids including delta‑8, delta‑10, HHC, etc., requiring ingestible hemp products to contain less than 0.3% potentially intoxicating cannabinoids and maintain a non‑intoxicating to intoxicating cannabinoid ratio of more than 10:1 ([president.maine.gov](https://president.maine.gov/legis/statutes/7/title7sec2231.html?utm_source=openai)). Maine’s Department of Agriculture, Conservation and Forestry (DACF) administers the hemp program under Chapter 274 rules (effective February 2023) which require licensed growers, planting reports within 14 days, sampling and testing by ISO 17025 labs for delta‑9‑THC, THCA, and total THC, and destruction of crops exceeding 0.3% total THC on a dry‑weight basis ([maine.gov](https://www.maine.gov/dacf/php/hemp/documents/FinalChapter274_2-17-2023.pdf?utm_source=openai)). The rules align with USDA-approved state hemp plan and enforce sampling, inspection, and corrective action protocols ([maine.gov](https://www.maine.gov/dacf/php/hemp/documents/FinalChapter274_2-17-2023.pdf?utm_source=openai)).

Shipping guidance

Maine law does not explicitly regulate inbound shipping of hemp products beyond federal requirements. Licensed growers must comply with federal shipping rules. No state‑specific age verification or retailer registration for shipping hemp products is mandated under DACF hemp program.

Testing & COA guidance

Maine requires testing by ISO 17025‑accredited laboratories. COAs must report delta‑9‑THC, THCA, and total THC on a dry‑weight basis per Chapter 274 rules ([maine.gov](https://www.maine.gov/dacf/php/hemp/documents/FinalChapter274_2-17-2023.pdf?utm_source=openai)). Growers must retain COAs and submit planting and post‑harvest reports. Crops exceeding 0.3% total THC must be destroyed per DACF instructions ([www1.maine.gov](https://www1.maine.gov/dacf/php/hemp/index.shtml?utm_source=openai)).

What to buy

Products derived from hemp with delta‑9‑THC ≤ 0.3% dry weight, total THC ≤ 0.3% dry weight, and ingestible products with non‑intoxicating cannabinoid ratio > 10:1 are permitted. Topicals, ingestibles, food, food additives, beverages derived from hemp are allowed if compliant ([president.maine.gov](https://president.maine.gov/legis/statutes/7/title7sec2231.html?utm_source=openai)).

What to avoid

Avoid products exceeding 0.3% delta‑9 or total THC. Products with potentially intoxicating cannabinoids (e.g., delta‑8, delta‑10, HHC) in aggregate ≥ 0.3% or with non‑compliant cannabinoid ratios are restricted. Synthetic hemp‑derived cannabinoids are excluded from the hemp definition and may be prohibited ([legislature.maine.gov](https://legislature.maine.gov/backend/App/services/getDocument.aspx?documentId=100665&utm_source=openai)). Smokable hemp flower is not separately banned but must meet THC limits.

• Total THC ≤ 0.3% dry weight per Maine DACF hemp program rules
• Licensed grower required for planting, harvesting, processing hemp (7 M.R.S. § 2231)
• ISO 17025 lab testing required with COA including delta‑9, THCA, total THC (Chapter 274 rules)
• Crops exceeding THC limit must be destroyed per DACF rules
• Potentially intoxicating cannabinoids regulated under 2025 amendments (PL 2025, c. 416)
