Why this matters

If you are exploring medical cannabis, you may have heard about capsules, oils, or other extracts. These are sometimes called non-flower formulations. They can be taken orally or under the tongue, and they come in measured doses. For some patients, this can feel more familiar than inhaling flower.

However, availability, suitability, and prescribing decisions are led by your clinician. Formulations can change, and this guide is here to help you have a more informed conversation with your clinic or pharmacist, not to steer a treatment choice.

Research into medical cannabis is still developing. The NHS, NICE, and the MHRA provide guidance, but individual responses to different formulations vary. Your prescriber will consider your medical history, other medications, and what has or hasn’t worked before.

What are capsules and extracts, and how are they different?

Capsules and extracts (including oils, tinctures, and softgel capsules) contain cannabinoids like THC and CBD in a measured dose. Unlike flower, which is inhaled, these are usually taken by mouth. This means they are absorbed through the digestive system, which can lead to a slower onset of effects—often 30 minutes to two hours—and a longer duration.

Because the dose is fixed in each capsule or drop, you cannot easily adjust it mid-session. This can be helpful for consistency, but it also means that finding the right dose may take time and careful monitoring with your clinician.

It is important to understand that no formulation is inherently better or worse. Your clinician will decide based on your condition, your goals, and your tolerance. For more on the differences between oil and flower, see our guide on medical cannabis oil vs flower.

What to ask your clinic or pharmacy

These questions are designed to help you understand what is being offered, without assuming availability or suitability. Always follow your clinician’s advice on dosing and timing.

  • What specific formulation are you considering for me, and why? This helps you understand the reasoning behind the choice.
  • How does this option fit the treatment plan we are discussing? This keeps the conversation focused on your own care.
  • What does the THC:CBD ratio on this label mean? For more on this, see our guide on THC:CBD ratios explained.
  • Are there any product-specific instructions I need to check with the pharmacy? Storage and use instructions can vary between products.
  • How long should I expect before I notice any effect, and how long might it last? This helps set realistic expectations.
  • What is the clinic’s advice if I miss a planned dose or have a concern? Your clinic should provide clear safety instructions.
  • How will we review how I am getting on?
  • Are there any interactions with my other medications? Always check this with your pharmacist.
  • What is the cost, and is it likely to change? Private prescriptions can vary in price.

What this guide cannot decide for you

This guide cannot tell you whether capsules or extracts are right for you. It cannot promise that any specific product will be available, effective, or suitable. Your clinician is the only person who can make that decision, based on your individual circumstances.

For most unlicensed CBPMs, a specialist considers the available evidence, other treatment options and the individual patient’s circumstances before prescribing.

If you have concerns about side effects or lack of effect, contact your clinic or prescriber directly.
