Connecticut, USA hemp laws: quick overview

Connecticut defines “hemp” under Conn. Gen. Stat. § 22‑61j (effective per USDA‑approved state plan) as Cannabis sativa L. and derivatives with delta‑9 THC not more than 0.3% dry weight ([hempdata.io](https://hempdata.io/states/connecticut?utm_source=openai)). In 2025 legislation, the definition expanded to include cannabis derivatives with total THC up to 0.3%, excluding synthetic cannabinoids and products over 0.4 mg total THC per container ([cga.ct.gov](https://www.cga.ct.gov/2026/rpt/pdf/2026-R-0019.pdf?utm_source=openai)). Public Act 23‑79 (effective July 1, 2023) created “high‑THC hemp products,” defined by total THC thresholds: for edibles/topicals/transdermal patches >1 mg per serving or >5 mg per container; tinctures >1 mg per serving or >25 mg per container; concentrates/extracts >25 mg per container; or other products >1 mg per serving, >5 mg per container, or >0.3% dry‑weight flower/trim ([cga.ct.gov](https://www.cga.ct.gov/2023/rpt/pdf/2023-R-0169.pdf?utm_source=openai)). Moderate‑THC hemp products are those with total THC ≥0.5 mg and ≤5 mg per container (excluding infused beverages) under Conn. Gen. Stat. § 21a‑426 (effective January 1, 2025) ([portal.ct.gov](https://portal.ct.gov/cannabis/knowledge-base/categories/consumer-information/hemp-cbd-and-other-products?language=en_US&utm_source=openai)).

Shipping guidance

Inbound shipments of hemp products into Connecticut are allowed under the 2018 Farm Bill; shipments must include a COA from an ISO/IEC 17025‑accredited lab confirming delta‑9 THC ≤ 0.3% dry weight ([hempdata.io](https://hempdata.io/states/connecticut?utm_source=openai)). No special import permit is required for finished hemp products. Retailers should implement age verification for delta‑8 or intoxicating hemp‑derived products due to enforcement focus ([hempdata.io](https://hempdata.io/states/connecticut?utm_source=openai)).

Testing & COA guidance

Manufacturers must obtain grower‑level test results showing ≤ 0.3% THC dry weight before using hemp ([portal.ct.gov](https://portal.ct.gov/-/media/dcp/hemp/hemp_laboratory_testing.pdf?utm_source=openai)). Independent testing by ISO/IEC 17025‑accredited labs is required for each batch before use in consumables; labs must be registered with DCP as controlled substance labs ([portal.ct.gov](https://portal.ct.gov/-/media/dcp/hemp/hemp_laboratory_testing.pdf?utm_source=openai)). COAs must include delta‑9 THC, CBD content, batch/lot number, test date, and lab accreditation number; retailers must retain COAs for three years ([hempdata.io](https://hempdata.io/states/connecticut?utm_source=openai)).

What to buy

Products with delta‑9 THC ≤ 0.3% dry weight (raw hemp, CBD products without THC) are legal. Moderate‑THC hemp products (total THC ≥ 0.5 mg and ≤ 5 mg per container) are legal if sold by registered vendors or cannabis establishments. High‑THC hemp products (exceeding thresholds) are legal only when sold by licensed cannabis establishments to adults 21+ or qualified patients.

What to avoid

Avoid products exceeding delta‑9 THC > 0.3% dry weight without proper cannabis licensing. High‑THC hemp products sold by unlicensed vendors are illegal. Synthetic cannabinoids are excluded from hemp definition and thus banned ([cga.ct.gov](https://www.cga.ct.gov/2026/rpt/pdf/2026-R-0019.pdf?utm_source=openai)). Infused beverages containing THC require cannabis establishment or package store waiver and are not moderate‑THC hemp ([portal.ct.gov](https://portal.ct.gov/cannabis/knowledge-base/categories/consumer-information/hemp-cbd-and-other-products?language=en_US&utm_source=openai)).
