Maine, USA hemp laws: quick overview

Maine defines “hemp” as Cannabis sativa L. and derivatives with delta‑9‑THC not more than 0.3% on a dry weight basis, matching federal law (7 MRSA §2231, PL 2019, c. 528; amended PL 2025, c. 416) ([legisweb0.legislature.maine.gov](https://legisweb0.legislature.maine.gov/statutes/7/title7sec2231.html?utm_source=openai)). The Department of Agriculture, Conservation and Forestry (DACF) administers licensing for growers, requiring planting reports within 14 days and COAs from ISO 17025 labs; rules codified in Chapter 274 (effective Feb 17 2023) align with USDA and include measurement of uncertainty in THC testing ([maine.gov](https://www.maine.gov/dacf/php/hemp/?utm_source=openai)). In 2025, Maine added regulation of “potentially intoxicating cannabinoids” (including delta‑8, delta‑10, delta‑9 isomers, HHC, etc.) and defined “potentially intoxicating hemp products” as those with ≥ 0.3% such cannabinoids or a non‑intoxicating to intoxicating ratio exceeding 10:1; these products may only be sold to persons 21+ and must use child‑resistant packaging (PL 2025, c. 416, §§1‑5) ([legisweb0.legislature.maine.gov](https://legisweb0.legislature.maine.gov/statutes/7/title7sec2231.html?utm_source=openai)).

Shipping guidance

Maine law does not explicitly address shipping hemp or hemp‑derived cannabinoids. Inbound shipments are permitted under federal law, but no state‑specific age verification or retailer registration rules for shipping are defined in statute or DACF rules.

Testing & COA guidance

Maine requires Certificate of Analysis from ISO 17025‑accredited labs showing delta‑9‑THC, THCA, and total THC on a dry weight basis per Chapter 274 rules (definitions I.A and I.B) ([legislature.maine.gov](https://legislature.maine.gov/doc/5665?utm_source=openai)). COAs must accompany planting reports and be retained; testing includes measurement of uncertainty. No additional panels specified in statute.

What to buy

State‑legal products include hemp biomass, seeds, clones, and ingestible or topical products derived from hemp containing ≤ 0.3% delta‑9‑THC dry weight, and non‑intoxicating cannabinoids (CBD, CBG, etc.) per 7 MRSA §2231 definitions ([legisweb0.legislature.maine.gov](https://legisweb0.legislature.maine.gov/statutes/7/title7sec2231.html?utm_source=openai)).

What to avoid

Avoid products containing “potentially intoxicating cannabinoids” above thresholds (≥ 0.3% or ratio > 10:1), as these are regulated and restricted to 21+ with packaging requirements. Forms like smokable hemp flower are not separately banned but must meet THC limits; delta‑8, delta‑10, HHC, THCa flower are “potentially intoxicating cannabinoids” and thus restricted under PL 2025, c. 416 ([legisweb0.legislature.maine.gov](https://legisweb0.legislature.maine.gov/statutes/7/title7sec2231.html?utm_source=openai)).

How to shop compliant, tested hemp

• Delta‑9 THC ≤ 0.3% dry weight aligns with federal baseline (7 MRSA §2231)
• Potentially intoxicating cannabinoids regulated under PL 2025, c. 416
• Grower must hold DACF license and submit planting report within 14 days
• COA from ISO 17025 lab required per Chapter 274 rules
• Potentially intoxicating hemp products restricted to 21+ and require child‑resistant packaging
