How Much Can You Buy From a Florida Dispensary at a Time?

A Florida dispensary can sell a qualified patient up to 2.5 ounces of smokable marijuana in any rolling 35-day period, plus up to 24,500 milligrams of THC in non-smokable products across a rolling 70-day supply. Those are the statewide ceilings, and how much you can buy from a Florida dispensary at a time also depends on what your physician has actually authorized in the Medical Marijuana Use Registry, which may be less than the maximum.¹

Only patients with an active Florida registry ID card can buy at all. The state does not recognize medical cards from other states, so out-of-state visitors cannot purchase from a Florida dispensary regardless of what their home program allows.²

Smokable Marijuana: 2.5 Ounces Every 35 Days

The smokable flower cap is 2.5 ounces per 35-day rolling window.¹ It is not a calendar month. The 35 days count forward from each dispensing event, so the amount you have available at any given moment depends on what you have already bought in the preceding weeks.

A separate possession cap applies on top of the purchase cap. You cannot have more than 4 ounces of smokable marijuana in your possession at any time, even if your rolling purchase total would technically leave room to hold more.¹

Your physician decides how much of the 2.5-ounce ceiling to actually authorize based on your condition. Not every patient is written for the full amount.

Non-Smokable Products: Measured in Milligrams of THC

For anything other than flower, Florida stops counting weight and starts counting THC. The state sets a daily dose cap for each delivery method, and those daily amounts feed into a 70-day rolling supply calculation.³

Edibles: 60 milligrams of THC per day
Inhalation, such as vaporization: 350 milligrams of THC per day
Oral products like capsules and tinctures: 200 milligrams of THC per day

Across every non-smokable form combined, your 70-day supply cannot exceed 24,500 milligrams of THC.³ Again, your physician’s order sets your personal ceiling, which can be lower than the statutory maximum.

How the Registry Enforces These Limits

Every sale runs through the Medical Marijuana Use Registry in real time. Before ringing up a purchase, the dispensary checks that your card is active, pulls your physician’s current order, and looks at how much of your rolling allotment is still available. If a transaction would push you over any applicable cap, the system blocks it.⁴

The tracking is centralized. Visiting different dispensaries will not reset your counter, because every licensed Medical Marijuana Treatment Center pulls from the same database. You can log into the registry yourself to see exactly how much you have left before making a trip.

When Your Physician Can Request More

If the standard caps do not meet your medical needs, your physician can file a Request for Exception through the registry. The request has to include a statement of the anticipated medical benefit of a higher dose, and the Office of Medical Marijuana Use has 14 days to approve or deny it.¹

The exception process covers the daily dose caps, the 35-day smokable supply, and the 4-ounce possession limit. If the OMMU returns the form, the physician may need to add medical records or a more detailed benefit statement before resubmitting.⁵ Not every request is approved, so exceptions work best when the physician can clearly document why the standard amounts are insufficient.

Caregiver Purchases Count Against the Patient

A registered caregiver can shop for a patient who cannot make the trip themselves. Whatever the caregiver buys applies to the patient’s allotment as set by the patient’s physician. There is no separate caregiver allowance.¹

Caregivers must be at least 21, be Florida residents, and pass a Level 2 background screening unless they are a close relative of the patient. They also need their own registry ID card and must carry it whenever they possess marijuana or a delivery device for the patient.⁶

Two Renewal Dates That Can Cut Off Your Access

Two separate clocks control whether you can buy anything at all, and they run on different schedules.

Your registry ID card is valid for one year and renews annually. You can submit the renewal application up to 45 days before expiration.⁴

Your physician certification, the actual order that authorizes purchases, expires every 210 days. That is roughly seven months, so it lapses before your card does. If the certification expires, the dispensary system will block sales even if your card still shows valid. Both dates are worth tracking on their own.

If You Go Over Your Limits

Because the registry blocks overpurchases at the point of sale, most patients never hit this problem at the counter. Possessing more marijuana than your recommendation allows, though, puts you outside the medical program’s protections and back under standard Florida drug possession law.

On the administrative side, the OMMU can suspend or revoke your registry card. A 2025 law expanded that authority, requiring immediate suspension for any patient or caregiver convicted of trafficking or possession with intent to sell.¹ The practical safeguard is straightforward: check your remaining allotment in the registry before each visit, keep both renewal dates on the calendar, and if the standard caps consistently fall short, ask your physician about an exception request rather than working around the system.
