Everything below is real. You can’t buy it here yet.

The CT regulator, statutes, tax stack and track-and-trace on this page are researched and current. We can set up stores in Washington and Arizona today, and CTis not one of them — so there is nothing to sign up for here, and we won’t pretend otherwise. (Washington’s CCRS is still the only track-and-trace we have integrated; Arizona mandates none, which is why it could open without one. A state that mandates one needs that adapter built first.)

Statutes that bite

Citation	Subject
Conn. Gen. Stat. §21a-420 et seq.	Regulation of Adult-Use Cannabis, chapter 420h — the act defined there as RERACA; §21a-420 itself is the definitions section
Conn. Gen. Stat. §21a-408 et seq.	Palliative Use of Marijuana, chapter 420f — the medical program; §21a-408 itself is the definitions section
RCSA §21a-408	DCP palliative-use (medical) regulations, §21a-408-1 to -72 — written certifications, patient and caregiver registration, dispensary PMP reporting, producer transportation. Adult-use is NOT in this series
Conn. Gen. Stat. §12-330ll	Potency-tier excise tax statute (0.625-2.75¢ per mg THC)

Tax stack

Excise

Through 2026-09-30: potency-tier excise per mg THC — 0.625¢ (flower) / 2.75¢ (edibles) / 0.9¢ (other), calculated per-product at point of sale rather than as a flat percentage. From 2026-10-01 that model is REPEALED: Public Act 26-68 §264 replaces Conn. Gen. Stat. §12-330ll with a flat 10.75% excise on gross receipts. Same sale, two different bases either side of the date — worth knowing before your September and October numbers refuse to reconcile.

Sales / Use

6.35% Connecticut state sales tax + 3% municipal cannabis tax (mandatory, not optional). Total state-stack: 9.35% on adult-use. MEDICAL IS TAX-FREE, NOT MERELY EXEMPT FROM THE 3%: DCP’s medical-marijuana programme page states participants “have the benefit of tax-free products when purchased from a dispensary facility or hybrid retailer” — so the relief covers the 6.35% as well, and it is scoped to the SELLER’s licence type. Charging a registered patient the state sales tax over-collects 6.35% on every purchase.

Local option

3% municipal cannabis tax is mandatory, applied uniformly statewide — no local-option variance, so there is no city/county rate to look up.

Compliance topics surfaced in-platform

Age 21+ adult-use / 18+ medical at the register — or an emancipated minor under eighteen, who is a qualifying patient in their own right (Conn. Gen. Stat. §21a-408(20)(C)(ii)); an unemancipated minor patient transacts through the custodial parent or guardian, who the statute requires to control acquisition
BioTrack CATS-shaped inventory + sales reports on the DCP cadence for licensee submission (CATS is the DCP-administered Cannabis and Tracking System for both medical and adult-use reporting) — direct BioTrack integration is not built
Potency-tier excise calculation per product — through 2026-09-30 the Department of Revenue Services taxes per mg of total THC AS REFLECTED ON THE PRODUCT LABEL (Conn. Gen. Stat. §12-330ll: 0.625¢ plant material / 2.75¢ edibles / 0.9¢ other), with returns filed to DRS, not DCP. From 2026-10-01 the model changes; see the tax notes on this page
Patient registry lookup hook (Connecticut Medical Marijuana Patient ID)
Daily point-of-sale-to-CATS reconciliation plus 7-day physical-inventory reconciliation (DCP Policies & Procedures §21a-421j-5(f)), with every activity logged to CATS within one hour — shaped for DCP record-keeping
Social-equity license-class flagging (CT prioritized social-equity applicants in the 2022-2023 conversion)

What CannAgent is built toward for CT

Adult-use + medical product lanes with separate tax stacks
BioTrack CATS-shaped inventory + sale receipt mirror
Daily reconciliation report (auto-runs at close)
Manager write-up assistant configurable to CT labor + DCP rule taxonomy

Coverage here — honestly

Connecticut coverage is written against DCP rules: the bulletins, the excise on both sides of its 2026-10-01 base change — potency-tier per mg THC through 09-30, a flat 10.75% of gross receipts after, under Public Act 26-68 §264 — the 9.35% state stack with no local-option variance, the medical-vs-adult-use 3%-municipal split, and the social-equity license-class topology from the 2022-2023 conversion. We keep it current as the DCP moves, and where something isn’t built for CT yet we say so before you sign — today that means the audit engine will not build a Connecticut filing for October 2026 or later until the gross-receipts basis is settled, because the repeal also strikes the product-class definitions the per-mg basis depended on.
