Missouri, USA hemp laws: quick overview

Missouri law defines “industrial hemp” as Cannabis sativa L. (any part) with an average delta‑9 THC concentration not exceeding 0.3% on a dry‑weight basis, or the maximum allowed under federal law, whichever is greater (RSMo §195.010, effective now) ([revisor.mo.gov](https://www.revisor.mo.gov/main/OneSection.aspx?bid=35415&section=195.010&utm_source=openai)). Under HB 2641 (Intoxicating Cannabinoid Control Act), signed April 23, 2026, and effective November 12, 2026, all hemp‑derived cannabinoid products—including those with synthetic cannabinoids, delta‑9 THC above naturally occurring levels, or marketed as smokable/vapeable or edible forms—are reclassified as marijuana and regulated under Article XIV of the Missouri Constitution (RSMo §195.900) ([revisor.mo.gov](https://revisor.mo.gov/main/OneSection.aspx?bid=59932&section=195.900&utm_source=openai)). Until that effective date, hemp and hemp‑derived intoxicating cannabinoids remain largely unregulated at the state level, though the Missouri Department of Health & Senior Services has issued advisories warning consumers to avoid products containing delta‑8, delta‑10, THCA, HHC, and similar compounds due to lack of regulation and safety data ([health.mo.gov](https://health.mo.gov/news/dhss-issues-health-advisory-regarding-risks-associated-consumption-hemp-derived-intoxicating?topic=&wrapped=true&utm_source=openai)). The Missouri Attorney General issued a cease‑and‑desist in March 2026 directing sellers to stop offering products with delta‑9 THC over 0.3% dry weight and to avoid deceptive marketing implying marijuana dispensary status ([ago.mo.gov](https://ago.mo.gov/wp-content/uploads/CeaseandDesistGrayAreaCannabis.pdf?utm_source=openai)).

Shipping guidance

Until November 12, 2026, interstate shipment of hemp is permitted under federal law and Missouri does not restrict transport (RSMo §195.900) ([revisor.mo.gov](https://revisor.mo.gov/main/OneSection.aspx?bid=59932&section=195.900&utm_source=openai)). After that date, hemp‑derived cannabinoid products will be regulated as marijuana and subject to Article XIV licensing and transport rules; only licensed marijuana facilities may handle them. Age verification (21+) and retailer licensing will be required under the marijuana framework.

Testing & COA guidance

Missouri defers to USDA hemp testing protocols for hemp crops, requiring total THC testing pre‑harvest (post‑decarboxylation) under USDA rules ([health.mo.gov](https://health.mo.gov/safety/cannabis/pdf/hemp-derived-cannabinoids.pdf?utm_source=openai)). There is no state‑specific ISO 17025 requirement or COA retention rule publicly available for hemp; after November 12, 2026, testing will follow marijuana testing facility standards under Article XIV (RSMo §195.900).

What to buy

Currently legal: hemp flower, seeds, fiber, grain, topical or ingestible products derived from industrial hemp with delta‑9 THC ≤ 0.3% dry weight (RSMo §195.010).

What to avoid

Avoid hemp‑derived intoxicating cannabinoids such as delta‑8 THC, delta‑10 THC, THCA, HHC, and similar compounds—these are unregulated and advised against by DHSS ([health.mo.gov](https://health.mo.gov/news/dhss-issues-health-advisory-regarding-risks-associated-consumption-hemp-derived-intoxicating?topic=&wrapped=true&utm_source=openai)). After November 12, 2026, any hemp‑derived cannabinoid product exceeding natural delta‑9 levels or containing synthetic cannabinoids will be treated as marijuana and must not be sold outside licensed dispensaries (HB 2641) ([revisor.mo.gov](https://revisor.mo.gov/main/OneSection.aspx?bid=59932&section=195.900&utm_source=openai)).
