Study breakdown

Most Australian gastroenterologists don't support cannabis for IBD despite patient demand

Cross SectionalModerate evidence
The takeaway

Only 21% of Australian gastroenterologists supported medical cannabis for IBD and just 6% understood current access pathways, despite 39% having patients already using cannabis and ranking it safer than steroids, immunomodulators, and biologics.

Gastroenterologists, IBD patients, and medical cannabis access advocates.

21% supported MC for IBD; only 6% knew access pathways

What the researchers found

39% had patients using medical cannabis. Only 21% supported MC in IBD. Only 28% wanted to prescribe. Just 6% understood access pathways. Only 31% felt comfortable discussing MC with patients. 20% cited adverse effects as a barrier. Driving impairment (64%) and developing brain effects (56%) were top concerns. Yet most ranked MC as less hazardous than steroids, immunomodulators, and biologics. 53% supported patient participation in clinical trials.

Why it matters

The disconnect between patient use (39% of specialists had MC-using patients) and specialist support (21%) creates a gap in clinical guidance.

The numbers in context

93 respondents (70 gastroenterologists, 23 trainees). 39% had MC-using patients. 21% supported MC in IBD. 28% wanted to prescribe. 6% understood access pathways. 31% comfortable discussing. 64% concerned about driving. 53% supported clinical trials.

How the study worked

Anonymous 30-item survey of 70 Australian gastroenterologists and 23 trainees, collected April-August 2019.

What this study cannot tell us

Small sample from one country. Self-selected respondents may not represent all gastroenterologists. Survey conducted before some evidence updates.

How to read the evidence

Small survey with reasonable response quality, but limited to one country and potentially subject to selection bias.

When this study was published

2020 survey from 2019.

The bigger picture

Gastroenterologists may be more cautious than their patients about cannabis because they focus on disease modification (where evidence is lacking) rather than symptom relief (where patients report benefit).

Questions still open

  • Would more gastroenterologist education change prescribing patterns? Is the gap between patient use and specialist support widening or narrowing?

Common questions

Do gastroenterologists recommend cannabis for IBD?
In this Australian survey, only 21% supported cannabis for IBD and 28% wanted to prescribe, despite ranking it safer than standard IBD medications like steroids and biologics.
Do IBD patients use cannabis?
39% of gastroenterologists surveyed reported having patients using medical cannabis, often without clinical guidance, highlighting a gap between patient behavior and specialist knowledge.
