Maine, USA hemp laws: quick overview

Maine defines “hemp” under 7 M.R.S. §2231 (as amended by PL 2019, c. 528 and PL 2021, c. 669) as Cannabis sativa L. and derivatives with delta‑9‑THC concentration not more than 0.3% on a dry‑weight basis, aligning with federal law ([president.maine.gov](https://president.maine.gov/legis/statutes/7/title7sec2231.html?utm_source=openai)). In 2025, PL 2025, c. 416 introduced the concept of “potentially intoxicating hemp products,” defined as ingestible hemp‑derived products containing less than 0.3% potentially intoxicating cannabinoids and maintaining a ratio of non‑intoxicating to potentially intoxicating cannabinoids of at least 10:1 ([web.legis.maine.gov](https://web.legis.maine.gov/legis/statutes/7/title7sec2231.html?utm_source=openai)). That law also prohibits sales of such products to persons under age 21 and mandates child‑resistant, tamper‑evident packaging for non‑topical forms ([legislature.maine.gov](https://legislature.maine.gov/backend/App/services/getDocument.aspx?documentId=116982&utm_source=openai)). Maine’s hemp program is administered by the Department of Agriculture, Conservation and Forestry (DACF), which enforces USDA‑aligned THC limits (Total THC ≤ 0.3% dry weight), sampling, testing, and destruction protocols for non‑compliant crops ([maine.gov](https://www.maine.gov/DACF/php/hemp/index.shtml?utm_source=openai)).

Shipping guidance

Inbound shipments of hemp products are allowed provided they meet Maine’s hemp definition (Total THC ≤ 0.3% dry weight). There is no state‑specific age verification or retailer registration requirement for shipping, but potentially intoxicating hemp products must only be sold to persons 21+ and packaged per state rules.

Testing & COA guidance

Maine requires testing by ISO 17025‑accredited labs; 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)). Samples are split for retest; results above 0.3% delta‑9‑THC trigger license suspension/revocation and crop destruction unless retest requested within 10 days ([legislature.maine.gov](https://www.legislature.maine.gov/doc/5665?utm_source=openai)).

What to buy

State‑legal products include hemp biomass, extracts, ingestible and topical products derived from hemp containing ≤ 0.3% delta‑9‑THC dry weight, and potentially intoxicating hemp products meeting the < 0.3% intoxicating cannabinoid and ≥ 10:1 ratio rule, sold only to 21+.

What to avoid

Avoid any hemp‑derived products exceeding 0.3% delta‑9‑THC dry weight, or potentially intoxicating hemp products that fail the ratio or concentration thresholds. Forms like delta‑8, delta‑10, HHC, THCa flower are not specifically addressed and thus their status is unknown.

How to shop compliant, tested hemp

• Delta‑9 THC ≤ 0.3% dry weight per 7 M.R.S. §2231 (PL 2019, c. 528; amended PL 2025, c. 416)

• Potentially intoxicating hemp products restricted: < 0.3% potentially intoxicating cannabinoids and ≥ 10:1 non‑intoxicating to intoxicating ratio (PL 2025, c. 416)
• Sale of potentially intoxicating hemp products limited to age 21+ (PL 2025, c. 416)
• ISO 17025 lab COA required for THC testing (Maine DACF Chapter 274 rules)
