Arkansas Purchase Limit — 2.5 oz / 14-Day Rolling Period

Last verified: May 2026

The 2.5-Ounce / 14-Day Cap

Amendment 98 § 3(a) sets the patient cap: 2.5 ounces of usable marijuana per 14-day rolling period. ADH Rules § XV implements the cap, defining "usable marijuana" as flower, pre-rolls, edibles, concentrates, vape cartridges, tinctures, capsules, topicals, and transdermal patches — all measured at their dried-flower-equivalent weight under ADH’s conversion table.

Compared to other state programs, 2.5 oz / 14 days is a moderate cap: more permissive than Mississippi’s 24-MMCEU (~3.5 oz) / 30-day rolling cap, comparable to Pennsylvania’s 30-day supply, and less generous than Oklahoma’s 3-oz / 30-day default.

The Seed-to-Sale Tracking System

Arkansas operates a state-contracted seed-to-sale tracking system administered by the Alcoholic Beverage Control Division of DFA. Every transaction is logged in real time. When a patient or caregiver presents an Amendment 98 ID at any Arkansas dispensary, the budtender’s POS terminal queries the central tracking database to verify:

• Card validity (active, not expired, not suspended).
• Purchase history within the last 14 days from any Arkansas dispensary.
• Remaining purchase capacity under the 2.5 oz / 14-day cap.

The system enforces the cap statewide and to the minute: a patient cannot circumvent the cap by visiting multiple dispensaries on the same day or sequential days.

Possession vs. Purchase

Amendment 98 imposes a 2.5 oz purchase cap and a related possession-protection rule. A patient may legally possess the cannabis they have purchased through licensed dispensaries; possession beyond that quantity (or possession of cannabis not purchased through licensed dispensaries) falls outside Amendment 98 protection and back into Title 5, Chapter 64 criminal liability.

Practical implication: a patient who purchases 2.5 oz on Day 1 and then again 2.5 oz on Day 15 (the 14-day window has rolled forward) can legally possess up to 5 oz at the start of Day 15 if they have not yet consumed the Day-1 purchase. The cap is on purchase rate, not simultaneous possession.

Edible THC Cap

Cannabis-infused food or beverages may not exceed 10 milligrams of THC per serving (the de facto national standard for medical edibles). Products may not be designed in shapes "primarily consumed by and marketed to children." See edible THC cap page for full details.

No Hard Cap on Flower or Concentrate Potency

Unlike Mississippi (which imposes a unique 30%-flower / 60%-concentrate THC potency cap), Arkansas does not impose a hard THC cap on flower or concentrates. ADH Rules require potency testing — results must appear on labels — but the underlying flower or concentrate may legally exceed any specific THC-percentage threshold.

Where Consumption Is Prohibited

Amendment 98 § 4 and ADH Rules forbid medical-cannabis consumption:

• On the grounds of any school.
• In any motor vehicle (driver or passenger).
• In correctional facilities.
• In childcare facilities.
• In any health facility where smoking is forbidden by the Arkansas Clean Indoor Air Act of 2006.
• In the presence of anyone under 14.
• In the presence of a pregnant woman.
• In any place where "an individual could reasonably be expected to be observed by others" — effectively a public-consumption ban.

Visiting-Patient Cap

Visiting patients (non-resident cardholders with a 30-day Arkansas visiting-patient card — see visiting-patient page) are subject to the same 2.5 oz / 14-day rolling cap.

Caregiver Capacity

A registered caregiver serving multiple patients may purchase up to each patient’s individual 2.5 oz / 14-day cap on behalf of that patient. The caregiver’s total capacity is therefore per-patient-additive: a caregiver serving the maximum 5 patients can transact up to 5 × 2.5 oz / 14 days = 12.5 oz / 14 days, but each patient’s 2.5 oz portion is tracked to that patient. The caregiver may not consume any portion of caregiver-purchased cannabis.

Practical Patient Guidance

• Plan purchases around the 14-day rolling window. The system enforces the cap statewide; multiple dispensaries do not multiply the cap.
• Keep receipts. The Amendment 98 protection extends to legally purchased medicine; product without a corresponding dispensary receipt may not be Amendment-98-protected if challenged.
• Transport in original sealed packaging. Loose flower or unmarked containers in a vehicle can support a possession-with-intent inference.
• Do not exceed the cap by stockpiling. The system prevents new purchases; it does not retroactively legalize possession beyond the cap.
