🇬🇧 Is Medical Cannabis Legal in the UK?
Yes medical cannabis became legal on 1 November 2018. However, the NHS still limits prescriptions to rare and severe conditions like:
- Drug-resistant epilepsy

🌿 What Is Medical Cannabis and How Does It Work?
Medical cannabis includes cannabis-based medications that doctors prescribe for specific health conditions. These products consist of high-grade, lab-tested strains or extracts that contain:
- THC (tetrahydrocannabinol) – the psychoactive component
- CBD (cannabidiol) – non-intoxicating and therapeutic
Unlike recreational cannabis, these strains are cultivated under strict regulations to ensure safety, consistency, and medical-grade quality.
🔬 The Endocannabinoid System (ECS)
To understand how cannabis works, it’s important to learn about the ECS the body’s largest neurotransmitter system. It helps regulate key functions such as:
- Pain
- Mood
- Sleep
- Appetite
- Immune response
Cannabis interacts with ECS receptors in your brain and body. By mimicking the body’s natural endocannabinoids, it supports balance (homeostasis) and may relieve symptoms related to chronic conditions.

This method allows doctors to tailor treatment plans more precisely.
