Medical cannabis in the UK refers specifically to cannabis-based products for medicinal use (CBPMs). These products are manufactured to pharmaceutical standards, prescribed only by specialist clinicians, and supplied through controlled and compliant channels. Although they share origins with the broader cannabis plant, CBPMs differ significantly in formulation, cannabinoid profile, and clinical application.
For clinics, prescribers, and operational teams, understanding these differences is essential—not only for patient care, but also for governance, prescribing oversight, and regulatory compliance.
This guide explains the main types of CBPMs used in the UK today and outlines the key factors that influence clinical decision-making.
What Defines a Medical Cannabis Product in the UK?
A product is considered a CBPM when it meets strict criteria laid out under the Misuse of Drugs Regulations and relevant MHRA guidance. These include:
Pharmaceutical manufacturing standards, ensuring controlled cannabinoid levels and product consistency.
Specialist-only prescribing, meaning only doctors on the specialist register may initiate treatment.
Controlled drug handling, including appropriate documentation, secure storage, and pharmacy oversight.
Governance and monitoring, including clinical assessments, follow-up protocols, and pharmacovigilance.
Importantly, UK medical cannabis is not classified by strain types such as indica, sativa, or hybrid. Instead, decisions are based on formulation, cannabinoid content, and therapeutic need, reflecting an evidence-based, regulated approach.
Oil-Based Formulations
Oil-based CBPMs are the most commonly prescribed form in the UK. These products offer consistent dosing, predictable onset, and strong suitability for chronic or long-term symptom management.
Oils allow clinicians to titrate doses gradually, giving patients time to adjust while ensuring safety and symptom control. They are typically dispensed with measured droppers or syringes, enabling precise administration.
Because of their stability and consistent pharmacokinetics, oils are often selected as first-line CBPMs when establishing a patient’s treatment plan.
Flower-Based Products (for Vaporisation)
Flower-based CBPMs are prescribed less frequently than oils but remain an important option for patients who benefit from a faster onset of action. When vaporised using medically approved devices, flower can provide symptom relief within minutes.
This rapid onset can be clinically useful for conditions where symptoms escalate quickly. However, flower products have a shorter duration of effect and require careful patient education to ensure safe administration.
As with all CBPMs, specialist oversight is essential—not only to determine whether flower is appropriate, but also to ensure patients understand device use, dose control, and safety considerations.
Cannabinoid Profiles: THC, CBD, and Balanced Formulations
The therapeutic effect of CBPMs is heavily influenced by their cannabinoid profile. In the UK, products are generally categorised into three groups:
High-THC Products
These formulations may offer stronger symptomatic relief but require increased monitoring due to psychoactive effects and potential adverse reactions. Specialists typically start with low doses and titrate upward cautiously.
High-CBD Products
CBD-dominant CBPMs are non-intoxicating and are often selected for patients who may benefit from symptom relief without significant psychoactive effects. They are commonly used in chronic conditions, anxiety-related presentations, and seizure disorders.
Balanced THC: CBD Products
Balanced products provide a middle ground. CBD can modulate some of THC’s psychoactive effects, which may result in improved tolerability. These formulations are widely used for pain, spasticity, and complex symptom profiles.
Forms of Medical Cannabis Used in the UK
Oils and Tinctures
Oils are typically used sublingually or orally. They provide steady absorption and are easy for clinicians to integrate into structured dosing plans.
Flower (for Vaporisation)
Used only with approved devices, flower provides rapid but short-lived relief. It requires careful assessment to ensure suitability and safe titration.
Capsules and Oral Preparations
Capsules offer precise dosing and controlled administration. Their slower onset but longer duration can be beneficial for steady symptom control.
Topical Preparations
Non-systemic and applied directly to the skin, topicals may be used for localised discomfort without producing systemic psychoactive effects.
Each product type carries its own governance and monitoring requirements, making documentation and follow-up essential.
How Clinicians Select the Right Product
The choice of CBPM depends on several factors, including:
the patient’s primary symptoms
previous treatment responses
risk assessment and side-effect profile
lifestyle and practical considerations
controlled drug requirements
necessity for rapid vs sustained relief
Clinicians must justify their product choice within a governance framework that aligns with CQC expectations and demonstrates clear clinical reasoning.
Safety, Monitoring, and Regulatory Considerations
Although CBPMs can be well tolerated, they require careful monitoring. Potential side effects include dizziness, fatigue, nausea, or cognitive changes, especially with THC-rich formulations.
Clinics must maintain robust documentation, ensure appropriate follow-up appointments, and accurately manage controlled drug records.
Sourcing from licensed, compliant pharmacies is essential to guarantee product quality, batch tracking, and patient safety.
