Medical Cannabis Strains for Pain: Which Work Best in UK Clinics

Choosing Strains for Pain Relief

When medical cannabis is prescribed for pain in UK clinics, the prescribing clinician considers several factors: type of pain (neuropathic, inflammatory, spastic), time of day for use, patient tolerance, and previous cannabis experience. Different strains suit different pain presentations.

Indica vs. Sativa for Pain

The indica/sativa distinction is an oversimplification in scientific terms - the real differences lie in cannabinoid and terpene profiles. That said, the practical shorthand remains useful:

• Indica-dominant strains (high myrcene, caryophyllene): Full-body relaxation, sedation, muscle relaxation. Best for pain at night, muscle spasms, fibromyalgia, MS spasticity. Examples: Northern Lights, Granddaddy Purple, Skywalker OG.
• Sativa-dominant strains (high limonene, terpinolene): More cerebral, less sedating. Better for daytime pain where function must be maintained. Examples: Jack Herer, Durban Poison, Harlequin.
• Hybrid strains (balanced): The most commonly prescribed - covers both dimensions. Examples: Blue Dream, Gorilla Glue, Chemdawg.

Most Prescribed Pain Strains at UK Clinics

• Gorilla Glue 4: High THC (25-28%), high caryophyllene. One of the most frequently prescribed for chronic pain in UK clinics. Powerful body relaxation with mood elevation.
• Blue Dream: Balanced THC:CBD hybrid with high myrcene. Popular for neuropathic pain where full sedation is not required.
• ACDC: High CBD (15-20%), low THC. Preferred for inflammatory pain where psychoactivity is not desirable. One of the best-evidenced strains for anti-inflammatory effect.
• OG Kush: High THC with complex terpene profile. Widely available in UK clinics, commonly prescribed for severe chronic pain and end-of-day relief.
• Harlequin: Balanced CBD:THC (5:2 ratio). The most prescribed balanced strain in UK pain clinics - mirrors the Sativex ratio in whole-flower form.

THC Percentage: Does Higher Mean Better for Pain?

Not necessarily. UK clinical data shows that pain relief plateaus at moderate THC levels (15-20%) for many patients. Higher THC products (25%+) are more often prescribed for severe, treatment-resistant pain where lower-THC products have been inadequate. For new patients without cannabis tolerance, starting with moderate THC reduces the risk of adverse effects.

Terpene Profiles for Pain

For maximum analgesic effect, look for strains high in:

• Caryophyllene: Directly binds CB2 receptors. Anti-inflammatory and analgesic.
• Myrcene: Sedative, muscle-relaxing. Enhances THC absorption.
• Pinene: Anti-inflammatory. Also has bronchodilator properties useful for vaporisation.
