Maine, USA hemp laws: quick overview

Maine law 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, aligning with federal law (7 M.R.S. §2231(1‑A)(D), PL 2019, c. 528; revised PL 2021, c. 669) ([legislature.maine.gov](https://legislature.maine.gov/legis/statutes/7/title7sec2231.html?utm_source=openai)). In 2025, Maine amended the statute (PL 2025, c. 416) to explicitly categorize “potentially intoxicating cannabinoids” (including Δ8, Δ9, Δ10, HHC, etc.) and define “potentially intoxicating hemp products” as those containing less than 0.3% of such cannabinoids and maintaining a ratio of non‑intoxicating to intoxicating cannabinoids of at least 10:1 ([legislature.maine.gov](https://legislature.maine.gov/legis/statutes/7/title7sec2231.html?utm_source=openai)). The amendment also imposes age‑21 minimum sales and child‑resistant packaging requirements for these products (PL 2025, c. 416 §§4‑5) ([legislature.maine.gov](https://legislature.maine.gov/legis/statutes/7/title7sec2231.html?utm_source=openai)). Maine’s DACF administers hemp grower licensing, sampling, testing, and destruction of over‑limit crops; all hemp must meet USDA’s ≤ 0.3% total THC dry weight standard (Maine DACF hemp program) ([maine.gov](https://www.maine.gov/dacf/php/hemp/?utm_source=openai)).

Shipping guidance

Maine law does not explicitly regulate inbound shipping of hemp products beyond federal standards. However, potentially intoxicating hemp products must comply with age‑21 sales and child‑resistant packaging; no separate state shipping license is required.

Testing & COA guidance

Growers must allow DACF inspection and sampling; crops testing above 0.3% total THC dry weight must be destroyed (Maine DACF) ([www1.maine.gov](https://www1.maine.gov/dacf/php/hemp/index.shtml?utm_source=openai)). Maine requires third‑party COAs for seed/clone THC content documentation submitted with planting reports within 14 days of planting (Maine DACF) ([maine.gov](https://www.maine.gov/DACF/php/hemp/index.shtml?utm_source=openai)). ISO 17025 accreditation is not specified in state rules.

What to buy

Products derived from hemp with Δ9‑THC ≤ 0.3% dry weight and, for potentially intoxicating hemp products, < 0.3% intoxicating cannabinoids and ≥ 10:1 ratio of non‑intoxicating to intoxicating cannabinoids. Non‑intoxicating cannabinoids (CBD, CBG, CBC, CBN, THCV, CBDV, CBTC, CBL, CBE) are permitted.

What to avoid

Products containing potentially intoxicating cannabinoids above 0.3% or with ratio < 10:1 are prohibited. Δ8, Δ9, Δ10, HHC, THCa flower, and other intoxicating cannabinoids are restricted unless within thresholds. No smokable hemp ban noted.
