Connecticut, USA hemp laws: quick overview

Connecticut aligns with the 2018 Farm Bill baseline: “manufacturer hemp products” must contain no more than 0.3% Δ9‑THC on a dry‑weight basis (C.G.S. § 22‑61l) ([cga.ct.gov](https://www.cga.ct.gov/current/pub/chap_424.htm?utm_source=openai)). Beginning January 1 2025, Connecticut created a new category of “moderate‑THC hemp products” defined as products containing at least 0.5 mg and no more than 5 mg total THC per container, and for flower/trim, Δ9‑THC must remain ≤ 0.3% dry‑weight (C.G.S. § 21a‑426; portal.ct.gov guidance) ([portal.ct.gov](https://portal.ct.gov/cannabis/knowledge-base/articles/moderate-thc-hemp?utm_source=openai)). Products exceeding those thresholds (i.e., total THC > 5 mg/container or > 0.3% dry‑weight) are classified as “high‑THC hemp products” and regulated as cannabis, requiring sale only by licensed cannabis establishments (portal.ct.gov) ([portal.ct.gov](https://portal.ct.gov/cannabis/knowledge-base/articles/what-is-considered-a-high-thc-hemp-product?language=en_US&utm_source=openai)). Manufacturer hemp products must comply with labeling and packaging rules including COA QR code, batch number, cannabinoid concentrations, warnings, and child safety statements (C.G.S. § 22‑61m) ([cga.ct.gov](https://www.cga.ct.gov/2024/sup/chap_424.htm?utm_source=openai)). Connecticut prohibits synthetic cannabinoids in manufacturer hemp products (C.G.S. § 22‑61l) ([cga.ct.gov](https://www.cga.ct.gov/2024/sup/chap_424.htm?utm_source=openai)). Growers must conduct pre‑harvest sampling within 15 days of harvest; any hemp exceeding 0.3% Δ9‑THC must be embargoed, reported, and destroyed (C.G.S. § 22‑61l) ([cga.ct.gov](https://cga.ct.gov/2020/sup/chap_424.htm?utm_source=openai)).

Shipping guidance

Inbound shipments of hemp and hemp products are allowed under Connecticut’s USDA‑approved state plan; producers must be licensed by the Department of Agriculture (portal.ct.gov) ([portal.ct.gov](https://portal.ct.gov/DOAG/Regulatory/Regulatory/Connecticut-Hemp-Program?utm_source=openai)). There is no specific age verification requirement for shipping, but moderate‑THC hemp products must be sold only to persons 21+ and vendors must hold a certificate of registration (effective Jan 1 2025) ([portal.ct.gov](https://portal.ct.gov/cannabis/knowledge-base/articles/what-is-considered-a-high-thc-hemp-product?language=en_US&utm_source=openai)). Retailers of moderate‑THC hemp products must be licensed cannabis establishments or hybrid retailers; shipping directly to consumers likely requires such registration.

Testing & COA guidance

Connecticut requires pre‑harvest sampling and testing for Δ9‑THC; non‑compliant hemp must be embargoed and destroyed (C.G.S. § 22‑61l) ([cga.ct.gov](https://cga.ct.gov/2020/sup/chap_424.htm?utm_source=openai)). Manufacturer hemp products must include COA information via QR code or barcode linking to independent lab results, including total THC and cannabinoids ≥ 1% (C.G.S. § 22‑61m) ([cga.ct.gov](https://www.cga.ct.gov/2024/sup/chap_424.htm?utm_source=openai)). The state requires labs to be accredited per C.G.S. § 21a‑408‑59 (regulations) ([cga.ct.gov](https://cga.ct.gov/2024/sup/chap_424.htm?utm_source=openai)). COAs must be retained and accessible via packaging.

What to buy

Allowed products include manufacturer hemp products with Δ9‑THC ≤ 0.3% dry‑weight, and moderate‑THC hemp products (total THC ≤ 5 mg/container, Δ9‑THC ≤ 0.3% dry‑weight) sold by registered vendors to adults 21+.

What to avoid

Avoid products exceeding 5 mg total THC per container or Δ9‑THC > 0.3% dry‑weight (classified as cannabis). Synthetic cannabinoids are banned. High‑THC hemp products require cannabis licensing. Ensure products are not mislabeled or misleading.
