If you’ve ever read about medical cannabis in the UK, you might have come across the phrase “unlicensed specials.” For many patients and clinicians alike, these terms can be confusing. What exactly does it mean when a prescription is for an “unlicensed special,” especially in the context of how to get uk cannabis prescription medical cannabis? How does regulation shape how these products are sourced, dispensed, and used? And how is that different from what patients might expect—like smoking cannabis?
In this detailed explainer, we’ll unpack the meaning of “unlicensed specials” in UK healthcare, explain why prescribed medical cannabis is vaporized (never smoked), and outline the key responsibilities pharmacists have to ensure patient safety and compliance with regulations.
What Is an Unlicensed Medicine? The Definition in UK Regulation
Unlicensed medicines
are essentially medicines that don’t have a formal UK marketing authorization (a licence) from the Medicines and Healthcare products Regulatory Agency (MHRA). This authorization confirms a medicine is safe, effective, and manufactured to specific high standards.When a medicine doesn’t have this license, it is referred to as unlicensed. These medicines might still be legal to prescribe and supply but fall outside the usual regulatory approval process.
In pharmacy jargon, an “unlicensed special” (or simply “specials”) is a medicine made or imported to order because:
- It meets a specific patient need not covered by licensed products The product is temporarily unavailable in licensed form The formulation or strength required is not commercially available as a licence medicine
Examples outside cannabis might include rare hormone preparations, paediatric syrups of adult tablets, or specific topical creams.
What About Medical Cannabis?
In the UK, cannabis-based products for medicinal use (CBPM) that doctors prescribe are all classified as unlicensed specials because no licensed cannabis medicine currently exists for this purpose. This means every prescription involves a special order, and pharmacies check here must source and supply these in strict accordance with regulations.
Prescription Cannabis: Vaporised, Not Smoked
One crucial point about prescribed medical cannabis in the UK: it is meant to be vaporised, not smoked.
The media or informal talk often slips into the phrase “smokable cannabis,” but this is misleading and clinically important to clarify.
Why No Smoking?
Smoking cannabis involves combustion—the chemical process of burning plant material. Combustion creates harmful by-products such as carcinogens, tar, and carbon monoxide, which have been linked to respiratory problems and other health risks.
Vaporisation, by contrast, heats cannabis to a temperature that releases active cannabinoids (like THC and CBD) as a vapour without burning the plant matter. This significantly reduces or eliminates the combustion by-products.

Benefits of Vaporisation for Medical Use
- Health: Lower risk of lung irritation and toxic inhalant exposure. Dosing consistency: Vaporisation devices deliver more reliable doses than smoked cannabis which varies wildly in potency. Device safety: Prescribed vape devices are designed for medical use and regulated as part of the medicine supply chain.
Doctors and pharmacists emphasize vaporisation because it enables safer, more controlled cannabis therapy when prescribed.
The Device Is Part of the Treatment
Medical cannabis prescriptions don’t just cover the cannabis extract or flowers, but also the device used for vaporisation. This matters because the device affects how the medicine is delivered and absorbed.
Devices authorised or recommended in the NHS or private prescribing frameworks meet standards for:
- Temperature control to avoid combustion Dosing accuracy Ease of use for patients Safety and hygiene (to reduce contamination risk)
When a pharmacist dispenses an unlicensed special cannabis product, they often supply or advise on the appropriate vaporiser device as part of the treatment package.
Why Is Device Advice Important?
If a patient uses unsuitable equipment or tries to smoke the product, two risks arise:
Health dangers from toxic smoke and irregular dosing Loss of the intended clinical effectiveness due to poor deliveryTherefore, the device choice is a regulated part of the prescribing and dispensing process.

Pharmacy and GPhC Regulation Regarding Unlicensed Specials
Unlike licensed medicines, unlicensed specials require stringent oversight throughout sourcing, dispensing, and record-keeping. This oversight is to protect patients while allowing access to medicines where no licensed alternative exists.
Pharmacist Responsibilities
The General Pharmaceutical Council (GPhC) and MHRA provide clear guidance for pharmacists handling unlicensed specials:
- Assess appropriateness: Pharmacists must ensure that an unlicensed special is prescribed suitably, considering licensed alternatives first. Sourcing: Only obtain specials from reputable manufacturers or suppliers with quality assurance, to meet MHRA standards. Record keeping: Keep detailed records on sourcing, reception, dispensing, and patient counselling related to the unlicensed special. These enable traceability and audit compliance. Patient information: Provide clear information about the unlicensed status of the medicine, its expected benefits, and what monitoring is ongoing. Reporting: Report any adverse drug reactions or quality issues promptly to protect future patients.
Specials Sourcing & Record-Keeping in Practice
Practically speaking, pharmacies have dedicated procedures for unlicensed specials that include:
Verifying the prescription is from a registered medical practitioner authorised to prescribe unlicensed medicines Confirming the supplier’s MHRA compliance status Retaining batch numbers, manufacturing certificates, and supply chain documentation Documenting patient consent and counselling details Logging all communication with prescribers and manufacturersSummarizing the Cost and Safety - What Patients and Clinicians Need to Know
Because unlicensed specials are made to order or imported, they typically cost more than licensed medicines due to:
Cost Factor Explanation Impact on Price Custom Manufacture Made in small batches or bespoke formulation Higher than mass-produced licensed meds Quality Assurance Special testing and certification required Added lab and compliance costs Supply Chain Importation and specialised distribution Shipping and handling fees Professional Handling Extra pharmacist time for sourcing and record-keeping Consultation and dispensing feesPatients should always discuss costs upfront with prescribers and pharmacists and understand that despite the lack of licensing, strict regulatory frameworks exist to keep cannabis specials safe and effective.
Key Takeaway: The Bottom Line
“Unlicensed specials” means the the medicine isn’t yet formally licensed in the UK, but can still be prescribed and dispensed under strict regulation. For medical cannabis, this is the legal and clinical standard, with vaporisation devices built into treatment to protect patient health.
Pharmacists carry important responsibilities to source these specials properly, maintain detailed records, provide clear patient information, and manage the entire supply chain in line with GPhC and MHRA guidance.
That means if you’re prescribed medical cannabis in the UK, you’re getting a carefully regulated medicine—not simply something to smoke—delivered in a way that prioritises your safety and treatment consistency.
