Nebraska 5 Ounce / 30-Day Supply Rule

Last verified: May 2026

The Initiative 437 Possession Allowance

I-437 defines "allowable amount" as up to 5 ounces of cannabis at any given time. The statutory text:

"a Patient or Caregiver shall not possess more than the allowable amount, defined as: (1) up to five ounces of cannabis at any given time."

The 5 oz does NOT include the weight of any other ingredient combined with cannabis — meaning a 5-oz cannabis-content cap, not a 5-oz total-product-weight cap. A patient holding 10 oz of cannabis-infused olive oil at 5% cannabis content would be within the cap (0.5 oz cannabis equivalent).

The Commission’s 30-Day Purchase Cap

The April 13, 2026 formal regulations from the Nebraska Medical Cannabis Commission limit purchase to up to 5 ounces per 30 days per patient. This cap aligns purchase with the possession allowance and prevents patients from accumulating beyond the I-437 cap. The cap is imposed by the commission, not by I-437 itself.

The Commission’s 90-Day Delta-9 THC Cap

The April 2026 regulations also impose a cap of 5 grams of delta-9 THC per patient from the same dispensary in any 90-day period. This effectively limits concentrate purchases to a relatively small amount per quarter.

For context: a typical 1-gram vape cartridge contains 700-900 mg of delta-9 THC. A 5-gram delta-9 THC quarterly cap permits roughly 5-7 vape cartridges per 90 days from a single dispensary. Edibles are subject to similar mathematical constraint.

Advocate Challenge to the Caps

Sen. John Cavanaugh (D-Omaha) and Nebraskans for Medical Marijuana have publicly challenged the 30-day / 90-day caps as inconsistent with I-437’s text. Cavanaugh filed a formal regulatory complaint in October 2025 charging the commission with overriding voter intent on this and other commission-imposed restrictions (in-state-physician requirement, in-state-ownership requirement, 1,250-plant cultivator cap).

The challenge framework involves:

• Initiative 437 does not contain 30-day / 90-day purchase caps.
• The "exclusive" regulatory authority of the commission under I-438 must be exercised consistent with patient-protection purposes.
• The 5-gram delta-9 THC quarterly cap is below typical patient consumption for chronic-pain or PTSD treatment regimens.
• The cap creates a "pretext" for patients to obtain product from non-licensed sources, undermining the voter-mandated regulated framework.

The challenge has not yet produced a court ruling or commission rule change as of May 2026.

How the Caps Compare to Other Medical-Cannabis States

• Florida: 70-day supply rule (per Amendment 2 framework); typically 35 g delta-9 THC per 70 days.
• Pennsylvania: 90-day supply; typically 30-day rolling.
• Mississippi: 6 MMCEU (Mississippi Medical Cannabis Equivalency Units, 100 mg delta-9 THC each = 600 mg total) per 7 days.
• Alabama: 50 mg / 75 mg total THC daily cap; 70-day supply limit.
• Iowa: 4.5 g delta-9 THC per 90 days — the most restrictive program in the U.S. and roughly comparable to Nebraska’s commission-imposed 5 g per 90 days.
• Utah: 56-day supply rule with daily dosage limits; pharmacy-dispensing model.

Nebraska’s commission-imposed 5 g delta-9 THC / 90 days is among the most restrictive in the U.S. for medical-cannabis programs, comparable to Iowa’s 4.5 g cap.

Patient Strategies Under the Caps

Within the commission caps, patients may:

• Spread purchases across multiple licensed dispensaries (when more dispensaries open).
• Choose lower-potency products (flower with lower THC vs. concentrate) to maximize quantity within delta-9 cap.
• Use non-THC-bearing cannabinoid products (CBD, CBG, CBN) outside the cap.
• Coordinate with practitioner on dosing strategy.

The Multiple-Dispensary Workaround

The 5-gram delta-9 THC / 90-day cap applies "from the same dispensary." Theoretically, a patient could purchase 5 g delta-9 THC from each of multiple licensed dispensaries within a 90-day window without violating the regulatory cap. As of May 2026, with 0 operational dispensaries, this workaround is theoretical.

Practical Notes

• The 5-oz possession cap is in I-437 and protected by voter mandate.
• The 30-day / 90-day caps are commission-imposed and may be litigated.
• Possession beyond 5 oz reverts to the § 28-416 plant-form penalty schedule (above 1 lb = Class IV felony).
• Concentrate possession beyond commission caps reverts to the § 28-416(3) Class IV felony framework.
• Documentation is critical: keep practitioner recommendation, product labeling, and dispensary receipts to establish the affirmative defense.
