CBD Not Enough - When to Switch to Medical Cannabis

Many people start with store-bought CBD oil. It is easy to get, no prescription needed, and for some it genuinely helps with mild complaints. The problem shows up when symptoms are stronger and CBD simply is not enough.

In this article we explain how CBD differs from medical cannabis, how to tell that CBD alone is too little, and what moving to THC therapy under a doctor's care looks like.

These are two different things, even though both come from cannabis. In short:

The key difference is THC. Store CBD has only trace amounts, so it does not intoxicate but also has a limited effect. Medical cannabis contains real doses of THC and is therefore a prescription medicine. We compared this in more detail in our article on medical cannabis versus store CBD.

There is no rigid line, but there are a few signals worth discussing with a doctor:

If you recognise these situations, it is time to talk to a doctor about THC therapy. That does not mean you will get a prescription automatically - the decision depends on the medical assessment.

THC is psychoactive and has real side effects, which is why it is not available without a prescription. That is not a flaw but a safeguard: the doctor chooses the right product, the THC to CBD ratio and the dose for your problem, and then guides the therapy.

This spares you the trial-and-error approach on your own. It starts with a small dose and increases gradually (start low, go slow), which limits the risk of unpleasant effects.

The path is simple. You book an in-person visit with a doctor, describe your complaints and what you have already tried (including CBD), and the doctor assesses whether THC therapy is justified. If so, they issue an RpW e-prescription valid for 30 days.

We describe it step by step in our article on how to get a medical cannabis prescription. What to look for when choosing a clinic is explained in our guide on how to choose a cannabis clinic.

Do not buy THC products outside a pharmacy and without a prescription - it is not a legal medicine and you cannot be sure what it contains. Do not keep increasing store CBD endlessly hoping it will act like medical cannabis; they are two different products. If CBD is not enough, the right step is to talk to a doctor, not to experiment on your own.

How does CBD differ from medical cannabis?

Store CBD is a supplement with no prescription and a THC content below 0.2%, so it does not intoxicate and has a mild effect. Medical cannabis is a prescription medicine containing real doses of THC (from 1 to 22% in flower), selected and guided by a doctor.

How do I know CBD is too little for me?

Signals include symptoms persisting despite regular use, having to increase the dose with no effect, and a chronic complaint that interferes with functioning. That is when it is worth discussing THC therapy with a doctor.

Can I just buy a stronger THC product?

Not outside a pharmacy and without a prescription - it is not a legal medicine and you cannot be sure of its composition. THC products are available only by prescription, at a pharmacy.

Does switching to medical cannabis mean stopping CBD?

Not necessarily. How to combine or change therapy is decided by the doctor based on your symptoms and response. Do not change treatment on your own.

Will I get a prescription if CBD did not help me?

The lack of a CBD effect alone does not guarantee a prescription. The doctor assesses indications and contraindications and only then decides whether THC therapy is justified in your case.
