What Does ‘Unlicensed Specials’ Mean for Medical Cannabis Prescriptions?
Medical cannabis is now prescribed in the UK under carefully controlled conditions, but terms like “unlicensed specials” can confuse patients and even some healthcare professionals. This article explains what unlicensed specials mean in the context of medical cannabis prescriptions, why the UK strictly endorses vaporisation over smoking, and how pharmacies and pharmacists handle these medicines to ensure safe, effective treatment.
Understanding Unlicensed Medicine and Specials: The Basics
First, let’s clarify what an unlicensed medicine actually means. In the UK, medicines usually need a licence (or marketing authorization) from the MHRA (Medicines & Healthcare products Regulatory Agency) confirming they've been rigorously tested for safety, quality, and efficacy.
Unlicensed medicines lack this formal MHRA licence but are still legally prescribed and dispensed when licensed options are unavailable or inappropriate. When a specific formulation or strength is needed that’s not commercially available, pharmacies can source or manufacture these as “specials.”
In short: “Unlicensed specials” are tailor-made or specially sourced medicines without a formal MHRA license but legally used when needed.
Medical Cannabis as an Unlicensed Special
Most medical cannabis prescriptions today fall into the category of unlicensed specials. There is currently no MHRA-licensed cannabis product for medical use that covers all patient needs, so doctors work with specialist pharmacies to source standardized cannabis-based medicines as specials.
Why UK Medical Cannabis is Vaporised, Not Smoked
A frequent misconception is that prescribed cannabis is “smokable.” This is inaccurate in the UK. Clinical guidance and NHS policy strongly recommend vaporisation — not smoking — for medical cannabis patients. Here’s why this matters.
Vaporisation vs Combustion: The Health Difference
Smoking cannabis means burning plant material, which produces combustion by-products (tar, carbon monoxide, and toxic chemicals). These can harm the lungs and overall health over time.
- Combustion By-products: Carcinogens and lung irritants formed from burning.
- Vaporisation: Heating cannabis to a temperature that releases active cannabinoids as vapor, without combustion.
Clinical evidence shows vaporisation delivers the medicine’s active ingredients with fewer harmful chemicals, making it safer and more consistent for dosing.
Devices as Part of the Treatment Plan
The vaporiser device is integral to medical cannabis treatment. It’s not just “how patients take it,” but key for consistent dosing and reducing risks.
Doctors may prescribe specific vaporiser models validated for delivering measured doses. Pharmacies and patients both need training and support for device use — again, regulated as part of the medicine's safety.
Pharmacy and Pharmacist Responsibilities with Unlicensed Specials
When medical cannabis is prescribed as an unlicensed special, community and specialist pharmacies take on important legal and professional responsibilities regulated by the General Pharmaceutical Council (GPhC).

Specials Sourcing and Record Keeping
Pharmacies must source unlicensed cannabis products from reputable manufacturers or importers who meet quality standards. They must keep detailed records including:
- Supplier details and batch information. https://bizzmarkblog.com/is-a-budget-conduction-vaporiser-good-enough-for-medical-use/
- Manufacture and expiry dates.
- Quality assurance documentation.
- Patient’s prescription and clinical notes verifying need.
This traceability is essential best temperature setting for vapour for patient safety and regulatory compliance.
Pharmacist Professional Responsibilities
- Verification: Pharmacists check the prescription, ensuring it fits patient clinical history.
- Information Provision: Explain treatment, device use, possible side effects, and storage.
- Adherence Support: Confirm patients understand vaporisation vs smoking risks, device operation, and dosing.
- Reporting: Monitor and report adverse effects or supply issues promptly.
The GPhC Code of Conduct requires pharmacists to exercise professional judgement to safeguard patient safety at all stages.

Summary Table: Common Questions About Unlicensed Specials & Medical Cannabis
Question Answer What is an unlicensed medicine? A medicine without formal MHRA licence but legally prescribed when no licensed alternative exists. Are prescribed cannabis products licensed? No. Most prescribed medical cannabis products are unlicensed specials sourced for individual patients. Is it legal to prescribe cannabis for smoking? No. UK policy discourages smoking and prescribes cannabis via vaporisation devices only. Why vaporisation over smoking? Vaporisation avoids harmful combustion by-products, improving safety and dosing. What are pharmacist responsibilities? Ensure safe sourcing, check prescriptions, provide patient info, maintain records, support adherence.Final Thoughts: What Patients Should Remember
If you are prescribed medical cannabis in the UK, remember that it will be an unlicensed special medicine and must be used via a vaporiser device, not smoked. The pharmacy handling your medication is bound by strict rules to ensure quality and safety, including detailed record keeping and patient support.
Never assume your cannabis medicine is the same as recreational or “smokable” cannabis. The prescribing, dispensing, and administration process here is tightly regulated to protect your health, and your pharmacist is a key partner in this.
Understanding these points can empower you to have informed discussions with your healthcare team and get the best out of your treatment.
