Missouri, USA hemp laws: quick overview

Missouri law defines hemp as cannabis sativa with Δ9‑THC not exceeding 0.3% on a dry‑weight basis, or the federal maximum, whichever is greater (RSMo § 261.265; RSMo § 195.010) ([revisor.mo.gov](https://revisor.mo.gov/main/OneSection.aspx?bid=14103&hl=&section=261.265&utm_source=openai)). Hemp extract used for treating intractable epilepsy must contain no more than 0.3% THC by weight, at least 5% CBD, and no other psychoactive substances; possession is limited to 20 ounces per registrant, with waiver possible (RSMo § 195.207, effective August 28, 2023) ([revisor.mo.gov](https://www.revisor.mo.gov/main/OneSection.aspx?bid=53870&section=195.207&utm_source=openai)). As of now, hemp‑derived intoxicating cannabinoids (e.g., Δ8, Δ10, THCA) are unregulated and considered neither hemp nor marijuana until November 12, 2026, when HB 2641 (RSMo § 195.900) takes effect, reclassifying such products as marijuana and subjecting them to Article XIV licensing and regulation (effective November 12, 2026) ([revisor.mo.gov](https://www.revisor.mo.gov/main/OneSection.aspx?bid=59932&section=195.900&utm_source=openai)). The Missouri Attorney General issued a cease‑and‑desist in March 2026 directing that products with Δ9‑THC over 0.3% dry weight are illegal and must be sold only via licensed dispensaries (AGO March 23, 2026) ([ago.mo.gov](https://ago.mo.gov/wp-content/uploads/CeaseandDesistGrayAreaCannabis.pdf?utm_source=openai)).

Shipping guidance

Interstate shipment of hemp is permitted (RSMo § 195.900(6)) ([revisor.mo.gov](https://www.revisor.mo.gov/main/OneSection.aspx?bid=59932&section=195.900&utm_source=openai)). There are no state‑specific inbound shipping restrictions for hemp. Age verification and retailer registration requirements for hemp‑derived intoxicating cannabinoids will apply beginning November 12, 2026 under HB 2641; until then, such products are unregulated.

Testing & COA guidance

Missouri’s industrial hemp plan requires ISO 17025‑accredited labs and DEA registration for testing (per USDA‑approved state plan amendments) ([agriculture.mo.gov](https://agriculture.mo.gov/news/newsitem/uuid/82fc52ff-24fc-4605-a9d8-81eb1ae6f4aa/missouri-industrial-hemp-amendments-approved?utm_source=openai)). Hemp extract for epilepsy must comply with testing rules under RSMo § 195.207; specifics of panels and COA retention are governed by DHSS rules but not detailed in statute.

What to buy

Currently legal: industrial hemp products with Δ9‑THC ≤ 0.3% dry weight; hemp extract for epilepsy (≤ 0.3% THC, ≥ 5% CBD, ≤ 20 oz with registration).

What to avoid

Avoid hemp‑derived intoxicating cannabinoids (Δ8, Δ10, THCA, HHC, etc.)—unregulated until November 12, 2026 and advised against by DHSS (April 30, 2024) ([health.mo.gov](https://health.mo.gov/news/dhss-issues-health-advisory-regarding-risks-associated-consumption-hemp-derived-intoxicating?utm_source=openai)). Products with Δ9‑THC > 0.3% dry weight are illegal outside licensed dispensaries (AGO March 23, 2026) ([ago.mo.gov](https://ago.mo.gov/wp-content/uploads/CeaseandDesistGrayAreaCannabis.pdf?utm_source=openai)).
