Connecticut, USA hemp laws: quick overview

Connecticut’s baseline hemp definition aligns with the 2018 Farm Bill: hemp is cannabis with delta‑9 THC ≤ 0.3% dry‑weight (Conn. Gen. Stat. § 22‑61l) ([cga.ct.gov](https://cga.ct.gov/2020/sup/chap_424.htm?utm_source=openai)). Manufacturer hemp products must comply with this and cannot contain synthetic cannabinoids (Conn. Gen. Stat. § 22‑61l(v)) ([cga.ct.gov](https://www.cga.ct.gov/CURRENT/PUB/chap_424.htm?utm_source=openai)). In 2021, Senate Bill 1201 (effective July 1, 2021) redefined “cannabis” to include hemp products with total THC > 0.3% dry‑weight, including delta‑8, delta‑9, delta‑10, etc., meaning such products must be sold only by licensed cannabis establishments ([portal.ct.gov](https://portal.ct.gov/dcp/news-releases-from-the-department-of-consumer-protection/2021-news-releases/selling-thc-containing-hemp-products-is-now-illegal?archived=true&utm_source=openai)). The 2026 Office of Legislative Research report clarifies that “high‑THC hemp products” are defined as manufacturer hemp products with total THC exceeding either 1 mg per serving (up to 5 mg per container) or 0.3% dry‑weight for flower/trim (2026‑R‑0019, Jan 12 2026) ([cga.ct.gov](https://www.cga.ct.gov/2026/rpt/pdf/2026-R-0019.pdf?t=1785012825993&utm_source=openai)). Connecticut also created a “moderate‑THC hemp product” category: products containing 0.5–5 mg total THC per container. Starting January 1, 2025, these may be sold only by cannabis establishments or vendors holding a certificate of registration from the Department of Consumer Protection (Conn. Gen. Stat. § 21a‑426) ([cga.ct.gov](https://cga.ct.gov/current/PUB/chap_420j.htm?utm_source=openai)).

Shipping guidance

Connecticut allows shipment or transportation through the state of hemp lawfully produced under federal law (Conn. Gen. Stat. § 22‑61l(bb), effective June 4 2024) ([cga.ct.gov](https://www.cga.ct.gov/CURRENT/PUB/chap_424.htm?utm_source=openai)). Inbound shipments of compliant hemp are permitted. There is no state requirement for age verification or retailer registration for non‑THC hemp products; however, moderate‑THC hemp products require vendor registration, and high‑THC hemp products must be sold by licensed cannabis establishments.

Testing & COA guidance

Hemp producers must comply with federal and state sampling and testing procedures as adopted by the Commissioner (Conn. Gen. Stat. § 22‑61l(v), (d)) ([cga.ct.gov](https://www.cga.ct.gov/CURRENT/PUB/chap_424.htm?utm_source=openai)). Manufacturer hemp products must be tested per standards established under Conn. Gen. Stat. § 21a‑421j (added by P.A. 23‑79, effective October 1 2023) ([cga.ct.gov](https://www.cga.ct.gov/CURRENT/PUB/chap_424.htm?utm_source=openai)). ISO 17025 accreditation is not explicitly required in statute; COA retention requirements are not specified in available sources.

What to buy

CBD products derived from hemp with delta‑9 THC ≤ 0.3% dry‑weight are legal and treated as foods (Conn. Gen. Stat. § 22‑61l(w)) ([cga.ct.gov](https://cga.ct.gov/2020/sup/chap_424.htm?utm_source=openai)). Moderate‑THC hemp products (0.5–5 mg total THC per container) may be sold by registered vendors or cannabis establishments. High‑THC hemp products (total THC > 1 mg/serving or > 0.3% dry‑weight flower) are legal only via licensed cannabis retailers.

What to avoid

Avoid any hemp‑derived products containing total THC > 0.3% dry‑weight (including delta‑8, delta‑10, THCa, etc.) unless sold by licensed cannabis establishments. Synthetic cannabinoids are banned in manufacturer hemp products. Smokable hemp flower with total THC > 0.3% is treated as cannabis and restricted accordingly.
