Maine, USA hemp laws: quick overview

Maine defines “hemp” as Cannabis sativa L. and any part thereof with delta‑9‑THC concentration not more than 0.3% on a dry weight basis, consistent with federal law (Title 7 §2231, PL 2019, c. 528; revised 2021) ([legislature.maine.gov](https://legislature.maine.gov/legis/statutes/7/title7sec2231.html?utm_source=openai)). In 2025, Maine added definitions for “nonintoxicating cannabinoids” (e.g., CBD, CBG, CBN) and “potentially intoxicating cannabinoids” (including delta‑8, delta‑9, delta‑10, HHC, etc.) under Title 7 §2231 (PL 2025, c. 416) ([legislature.maine.gov](https://legislature.maine.gov/legis/statutes/7/title7sec2231.html?utm_source=openai)). The 2025 amendments also created a category of “potentially intoxicating hemp products,” defined as ingestible hemp‑derived products containing less than 0.3% potentially intoxicating cannabinoids and maintaining a ratio of at least 10:1 nonintoxicating to potentially intoxicating cannabinoids (PL 2025, c. 416) ([mainelegislature.org](https://www.mainelegislature.org/legis/statutes/7/title7sec2231.html?utm_source=openai)). These products may only be sold to individuals aged 21 or older (PL 2025, c. 416) ([mainelegislature.org](https://www.mainelegislature.org/legis/statutes/7/title7sec2231.html?utm_source=openai)). Under Title 22 §2158‑A (PL 2019, c. 528), food, food additives, or food products containing hemp or hemp‑derived CBD are not considered adulterated solely due to hemp inclusion, and their non‑medical sale is permitted (Title 22 §2158‑A) ([legislature.maine.gov](https://legislature.maine.gov/statutes/22/title22sec2158-A.html?utm_source=openai)).

Shipping guidance

Inbound shipments of hemp are permitted if compliant with state definitions and licensing. Growers must be licensed by Maine DACF. Age verification (21+) is required for potentially intoxicating hemp products. Retailers must hold appropriate licenses for ingestible hemp products (Title 7 §2231).

Testing & COA guidance

Maine DACF requires third‑party lab testing for THC content (COA) and sampling at planting and pre‑harvest; hemp must not exceed 0.3% Total THC by dry weight (Maine DACF Chapter 274 rules, Feb 17 2023) ([maine.gov](https://www.maine.gov/dacf/php/hemp/documents/FinalChapter274_2-17-2023.pdf?utm_source=openai)). COAs must be retained; ISO 17025 not specified in statute.

What to buy

State‑legal products include hemp flower, extracts, ingestible products, topicals, and food products containing hemp‑derived nonintoxicating cannabinoids (CBD, CBG, etc.) that meet ≤ 0.3% delta‑9 THC and, if containing potentially intoxicating cannabinoids, meet the 10:1 ratio and < 0.3% threshold.

What to avoid

Avoid products with > 0.3% delta‑9 THC, or ingestible products with potentially intoxicating cannabinoids that exceed 0.3% or fail the 10:1 ratio. No blanket ban on delta‑8, delta‑10, HHC, THCa, but they are regulated as potentially intoxicating cannabinoids. Smokable hemp is not banned under statute.
