Maine, USA hemp laws: quick overview

Maine defines “hemp” as Cannabis sativa L. and any part thereof with a delta‑9‑THC concentration not more than 0.3% on a dry weight basis, including measurement of uncertainty, aligning with federal law (7 MRS §2231, enacted via PL 2019, c. 528; effective upon enactment) ([mainelegislature.org](https://www.mainelegislature.org/legis/bills/bills_129th/chapters/PUBLIC528.asp?utm_source=openai)). The law allows unlicensed personal cultivation of up to three hemp plants on no more than one acre or within an indoor facility for personal use (7 MRS §2231(2)) ([mainelegislature.org](https://www.mainelegislature.org/legis/bills/bills_129th/chapters/PUBLIC528.asp?utm_source=openai)). Commercial growers must obtain a license from the Department of Agriculture, Conservation and Forestry (DACF), submit planting reports within 14 days of planting, and use certified seed sources or tested clones (7 MRS §2231(2‑A), (4)) ([mainelegislature.org](https://www.mainelegislature.org/legis/bills/bills_129th/chapters/PUBLIC528.asp?utm_source=openai)). Maine’s hemp program operates under USDA‑approved plan; all hemp must meet the federal Total THC ≤ 0.3% dry weight standard ([maine.gov](https://www.maine.gov/dacf/php/hemp/?utm_source=openai)). Sampling and testing rules (01‑001 CMR ch. 274 § IV) require pre‑harvest sampling of all lots unless exempt, quantitative testing for total THC, retention of split samples, retest rights, and destruction of non‑compliant lots; labs must be ISO 17025‑accredited ([law.cornell.edu](https://www.law.cornell.edu/regulations/maine/01-001-C-M-R-ch-274-SS-IV?utm_source=openai)).

Shipping guidance

Maine follows federal rules: interstate shipments of compliant hemp are allowed. There is no state‑specific restriction on inbound shipments. No age verification or retailer registration requirements are specified for hemp products under DACF rules.

Testing & COA guidance

All licensed hemp lots (unless exempt) must be sampled and tested for total THC prior to harvest under 01‑001 CMR ch. 274 § IV. Testing must be quantitative, with split samples retained, retest rights within 10 days, and ISO 17025‑accredited labs required ([law.cornell.edu](https://www.law.cornell.edu/regulations/maine/01-001-C-M-R-ch-274-SS-IV?utm_source=openai)). Certificates of Analysis must be sent to DACF within 24 hours of testing; non‑compliant lots require a disposal plan within 48 hours ([law.cornell.edu](https://www.law.cornell.edu/regulations/maine/01-001-C-M-R-ch-274-SS-IV?utm_source=openai)).

What to buy

State‑legal hemp products include those derived from hemp with total THC ≤ 0.3% dry weight, including CBD oils, edibles, topicals, fiber, seed products, and extracts. Maine law explicitly includes topical or ingestible consumer products derived from hemp within the definition of hemp (7 MRS §2231) ([mainelegislature.org](https://www.mainelegislature.org/legis/bills/bills_129th/chapters/PUBLIC528.asp?utm_source=openai)).

What to avoid

Products exceeding total THC > 0.3% dry weight are non‑compliant. Maine law does not explicitly address Delta‑8, Delta‑10, THCa, or HHC; their legal status under state law is unknown. Smokable hemp flower is not banned by state statute, though some retailers may restrict sales to under‑21s; public smoking may be restricted locally ([mainecannabis.org](https://mainecannabis.org/hemp?utm_source=openai)).
