How Medical Marijuana Dosage and Rolling Supply Limits Work

Florida’s medical marijuana dosage limits cap smokable flower at 2.5 ounces per rolling 35-day period and non-smokable products at 24,500 milligrams of THC per rolling 70-day period, with separate daily caps for each route of administration. The limits do not reset on a fixed calendar date. Instead, the Medical Marijuana Use Registry runs a continuous look-back and recalculates your available balance every day based on what you have purchased in the recent past.¹

How the Rolling Supply Window Works

Most people expect a monthly reset. Florida does not work that way. The registry looks back 35 days for smokable marijuana and 70 days for everything else, checking every transaction logged to your patient profile across every dispensary in the state.¹

Your available balance shifts each day. If you filled the entire smokable allotment on a single visit, none of it comes back until day 36, when that purchase ages out of the window. Partial purchases roll off in the amounts they were made. Dispensaries see your real-time availability before ringing up an order, so overages on the purchasing side rarely happen by accident.

Smokable Marijuana Limits

Smokable flower and pre-rolls are capped at 2.5 ounces per 35-day rolling period.² Visiting multiple dispensaries does not stretch this ceiling; the statewide registry tracks your cumulative total.

Possession is a separate cap. You cannot hold more than 4 ounces of smokable marijuana at any time, even if every ounce was purchased legally across multiple rolling periods.¹ All product must also remain in its original dispensary packaging.

Non-Smokable THC Dosage Limits

Non-smokable products are measured in milligrams of THC rather than weight of product. The aggregate cap across all non-smokable routes combined is 24,500 milligrams of THC per 70-day rolling period.³ That aggregate number can be misleading, because each route has its own daily cap. Reach your daily limit for edibles and you cannot buy more edibles that day, regardless of how much aggregate supply you still have.

The daily doses and 70-day supply caps by route:

Inhalation (vaporization): 350 mg daily, 24,500 mg per 70 days
Oral (capsules, tinctures): 200 mg daily, 14,000 mg per 70 days
Suppository: 195 mg daily, 13,650 mg per 70 days
Sublingual: 190 mg daily, 13,300 mg per 70 days
Topical (creams): 150 mg daily, 10,500 mg per 70 days
Edibles: 60 mg daily, 4,200 mg per 70 days

Every figure above is THC content, not product weight.³ A 100 mg gummy might contain 10 mg of THC, and it is the 10 mg that counts against your limit. Patients using more than one route need to track each route independently while staying under the 24,500 mg ceiling overall.

How Long a Certification Lasts

A physician certification can cover up to three 70-day supply periods for non-smokable products, or six 35-day periods for smokable marijuana, before a new certification is required.¹ When a certification lapses, you cannot purchase until your qualified physician renews it in the registry.

Requesting Higher Limits

If the standard caps do not provide adequate relief, your qualified physician can petition the Department of Health for an exception. The statute allows exceptions to the daily dose amounts, the 2.5-ounce smokable supply cap, and the 4-ounce smokable possession cap.¹ Only the treating physician can file; patients cannot submit the request on their own.

The physician submits Form DH8031-OMMU-08/2022 electronically through the Medical Marijuana Use Registry.⁴ The form requires:

The qualifying condition driving the need for a higher amount
The route and dose that has proven insufficient
A description of how the patient will benefit from the increase
The proposed minimum daily dose that would treat the condition adequately

The Department of Health has 14 days from receipt of complete documentation to approve or deny. If the department does not act within that window, the request is automatically deemed approved.¹ Your existing limits remain in effect during the review, and the registry updates to reflect any new authorized amounts once approval takes effect.

What Happens if You Exceed Your Limits

Going over the authorized amount carries layered consequences. The Department of Health can suspend or revoke your registry card if you obtain marijuana in amounts greater than your certification authorizes.¹ Losing the card means losing legal access.

Criminal exposure is more serious. The medical program’s protections apply only while you stay within its requirements. Once you possess more than your authorized amount, those protections fall away and Florida’s general drug statute takes over. Holding more than 20 grams of cannabis without legal authorization is a third-degree felony carrying up to five years in prison. Possession of 20 grams or less, outside program protections, is a first-degree misdemeanor punishable by up to one year in jail.⁵ The registry catches purchasing overages before they happen, but a possession violation can still occur if you fail to track what you already have at home.

Federal Boundaries the State Card Does Not Cover

Two situations sit outside what a Florida card can authorize, and readers commonly assume otherwise.

Firearms

Marijuana remains a Schedule I controlled substance federally. Federal law prohibits anyone who is an “unlawful user of or addicted to any controlled substance” from possessing firearms or ammunition.⁶ An ATF interim final rule effective January 22, 2026, revised the definition of “unlawful user” to require evidence of regular, ongoing use over an extended period rather than a single incident.⁷ A patient using medical marijuana regularly for a chronic condition almost certainly meets that threshold, and answering “no” to the drug-use question on ATF Form 4473 while holding an active card and using product routinely creates a federal false-statement exposure on top of the possession prohibition.

Air Travel

TSA does not actively search for marijuana, but officers must report any suspected legal violation found during screening to law enforcement.⁸ Airport checkpoints operate under federal jurisdiction regardless of whether the origin and destination states have legalized medical use. The only cannabis-related products that clear the federal threshold are those containing no more than 0.3 percent THC on a dry weight basis or products approved by the FDA. A Florida medical card does not override this.
