For consumers in Jacksonville, medical marijuana rules don’t change city-to-city—patients follow Florida’s statewide medical marijuana law. That matters because it keeps the “how much can I have?” question pretty clear, even if the way limits are tracked can feel confusing at first.

The big possession rule: “smokable flower” has a hard cap

For marijuana in a form for smoking (flower), Florida law sets a possession limit of 4 ounces at any given time—unless a physician requests and the Department of Health approves an exception for a specific patient.

Separately, Florida also limits dispensing/purchasing of smokable flower to no more than 2.5 ounces in any 35-day period (again, exceptions can be requested).

A common Jacksonville “oops” scenario is a patient who shops sales at multiple dispensaries and forgets what they already have at home. The registry tracks purchases, but possession is about what’s physically in the patient’s control. Staying under the 4-ounce cap is the safer “real-world” target.

Non-smokable products: tracked as a “70-day supply”

For vapes (inhalation), edibles, tinctures, capsules, topicals, and other routes, Florida uses a 70-day supply limit based on the physician certification and state dosing rules. Patients are not allowed to possess more than a 70-day supply.

Two compliance rules Jacksonville patients forget

Florida’s Office of Medical Marijuana Use also stresses two practical requirements:

• Keep products in original packaging from the licensed Medical Marijuana Treatment Center (MMTC).

• Carry and present your MMJ Registry ID card if law enforcement requests it. Refusing or failing to present it can be charged as a second-degree misdemeanor.

What happens if a patient breaks the limits?

If someone goes over the program limits—or has products that don’t meet the program rules (like not being in original packaging or not acquired from an MMTC)—they can lose the legal protections that normally shield patients from Florida’s general cannabis prohibitions.

From there, consequences can look like standard Florida possession enforcement. Under Florida law, possession of 20 grams or less of cannabis is a first-degree misdemeanor. And possession over 20 grams can be charged as a felony, which carries much higher stakes.

Final takeaway

Long-time consumers put it simply: treat the limits like guardrails—check your registry totals before buying, don’t stockpile flower beyond 4 ounces, and keep everything labeled and packaged. If something ever goes sideways, the difference between “compliant patient” and “unprotected possession case” can come down to small details.
