Medical Cannabis vs Over-the-Counter CBD: What Is the Difference?

The Regulatory Gap

• CBD supplements sold in UK shops are NOT medical cannabis
• Not prescribed by doctors, not manufactured to GMP standards, not regulated as medicines
• Independent testing repeatedly shows OTC CBD labels are inaccurate — often significantly so
• Prescribed medical cannabis operates within a pharmaceutical framework OTC CBD cannot match

Understanding the difference between OTC CBD and prescribed medical cannabis is essential for patients and carers.

The Prescription Advantage

• EU-GMP certified manufacturing — same standards as pharmaceutical drugs
• Accurate, third-party verified cannabinoid content confirmed by COA
• Can legally contain THC above the 1mg per container limit that applies to OTC products
• Clinical oversight: monitoring for drug interactions, optimising your dose
• Legitimacy: recognised by GP and all other healthcare providers

For patients with qualifying medical conditions, the quality and clinical oversight of prescribed EU-GMP certified cannabis is clinically superior to self-medicating with OTC supplements.
