When CBD Needs a Prescription in Costa Rica
The Line Is a Daily Dose, Not a Product
People assume CBD is either legal or it is not. In Costa Rica it is neither — it depends on how much you take in a day. Under the regulations covering cannabis and hemp products, a CBD product intended for a daily dose above 70 mg requires a medical prescription. Below that threshold it can be sold over the counter as a food, supplement or cosmetic.
That matters because the shop shelf gives you no indication of which side of the line you are on. A 30 ml bottle labelled 3,000 mg is entirely legal to buy. Whether the dose you end up taking from it requires a prescription depends on how you use it.
A Worked Example
Say you buy a 30 ml bottle containing 1,500 mg of CBD. That is 50 mg per millilitre, and a standard dropper holds about 1 ml.
- Half a dropper once a day — about 25 mg. Over the counter.
- One dropper once a day — about 50 mg. Still over the counter.
- One dropper twice a day — about 100 mg. Now a prescription medicine.
Nothing about the bottle changed. Only the dose did. And 100 mg a day is not unusual — it is well within the range people work up to when a lower dose is not doing much.
The Second Line: 1% THC
There is a separate threshold that catches people out. Costa Rican law divides cannabis at 1% THC by dry weight. Below 1% it is hemp, the category most CBD products fall into. At or above 1% it is psychoactive cannabis, which is pharmacy-only and prescription-only regardless of dose.
Full-spectrum products contain trace THC by design. Reputable ones stay well under the limit and prove it with a certificate of analysis. Products without one are a genuine risk — see our guide on how to read a cannabis label.
Why This Is Worth Getting Right
Two reasons, and neither is about penalties.
The first is medical. If you have reached a dose where a prescription applies, you have reached a dose where drug interactions become a real consideration — CBD affects the same liver enzymes that process many common medications. A prescriber can check that against what you already take. A shop assistant cannot.
The second is practical. A prescription puts your dose in a clinical record, which matters if you travel, if you are asked about your medications, or if you need to show that what you are taking was medically directed.
What to Do If You Are Above the Line
Work out your actual daily milligrams: bottle strength divided by volume, multiplied by how much you take. If it is over 70 mg, that is the point to speak to a physician — not to stop. A consultation establishes whether the dose suits what you are treating, whether it is interacting with anything, and whether a different ratio would serve you better.
Any physician in good standing with the Colegio de Médicos y Cirujanos can prescribe. You do not need a specialist, and you do not need residency — visitors use the same pathway.
