Study breakdown

UK medical cannabis patients with inflammatory bowel disease reported improvements over 18 months

ObservationalModerate evidence
The takeaway

IBD patients prescribed cannabis-based products in the UK showed improved quality of life, anxiety, and sleep scores over 18 months, though without a control group, the cause of improvement remains uncertain.

Gastroenterologists, IBD patients exploring cannabis-based treatments, and medical cannabis researchers

116 IBD patients tracked for 18 months

What the researchers found

Among 116 IBD patients in the UK Medical Cannabis Registry treated with cannabis-based products, there were statistically significant improvements in IBD-specific quality of life (SIBDQ), generalized anxiety (GAD-7), sleep quality (SQS), and general quality of life (EQ-5D-5L) over 18 months.

Why it matters

Long-term data on cannabis-based products for IBD is scarce. This 18-month follow-up from a real-world registry provides some of the longest observational data available for this patient population.

The numbers in context

116 patients; 81% male; mean age 39.5 years; significant improvements in SIBDQ, GAD-7, SQS, and EQ-5D-5L (all p < 0.05); 17.2% reported adverse events (155 total events)

How the study worked

Prospective registry study tracking 116 IBD patients prescribed cannabis-based medicinal products (CBMPs) through the UK Medical Cannabis Registry, with validated outcome measures collected from baseline through 18 months.

What this study cannot tell us

No control group so improvements could reflect natural disease course or placebo effects; predominantly male sample; registry data subject to selection bias; patients self-selected into cannabis treatment

How to read the evidence

Real-world registry study with validated outcome measures but no control group or randomization.

When this study was published

2024 study with 18-month follow-up data

The bigger picture

IBD treatment options remain limited for many patients. Real-world registry data like this can help identify whether cannabis-based products warrant further investigation through randomized controlled trials.

Questions still open

  • Would these improvements hold up in a randomized controlled trial with a placebo arm? What specific cannabis formulations and doses produced the best outcomes?

Common questions

What improved for IBD patients using medical cannabis?
Patients showed statistically significant improvements across multiple measures: IBD-specific quality of life, generalized anxiety, sleep quality, and general health-related quality of life over the 18-month treatment period.
Were there side effects?
About 17% of patients reported adverse events, with 155 total events recorded across the study population. The study authors note that causation cannot be inferred from this type of observational data.
