Full Spectrum vs Broad Spectrum: What UK Patients Need to Know
A guide to the practical differences between full spectrum and broad spectrum medical cannabis products, helping UK patients make informed decisions with their prescribing specialist.
One of the most common questions among UK patients new to medical cannabis concerns the difference between full spectrum and broad spectrum products. Understanding the distinction is important for patients when discussing options with their prescribing specialist and for setting expectations about treatment effects.
What Is Full Spectrum Cannabis
Full spectrum cannabis products contain the complete range of cannabinoids, terpenes, and other phytochemicals found in the original plant, including THC in its naturally occurring concentration. This means patients may benefit from the entourage effect, the synergistic interaction between multiple plant compounds that may enhance therapeutic outcomes.
- Contains THC alongside CBD, CBG, CBN, and other minor cannabinoids
- Terpene profile is preserved, contributing to effects and flavour
- Associated with stronger symptom relief for certain conditions, particularly pain and PTSD
- THC content means psychoactive effects are possible, especially at higher doses
What Is Broad Spectrum Cannabis
Broad spectrum products contain a range of cannabinoids and terpenes but have had THC specifically removed or reduced below a threshold. This approach aims to preserve entourage effect benefits while minimising psychoactive effects, making these products suitable for patients sensitive to THC or those who need to avoid it for professional or personal reasons.
- THC removed or reduced to below 0.2% or below detectable levels
- CBD, CBG, CBN, and terpenes retained
- Lower risk of psychoactive effects compared to full spectrum
- May be preferred for daytime use and patients with anxiety triggered by THC
Choosing the Right Product
The choice between full and broad spectrum is a clinical decision that should be made in consultation with your prescribing specialist. Factors including your condition, existing medications, lifestyle, and previous experience with cannabis will all inform the recommendation.
