What This Study Found

85.3% of GPs received patient inquiries about medicinal cannabis in the prior three months, but only 52.3% felt comfortable discussing it. Just 21.8% had prescribed a cannabis product, and 66.9% felt they had inadequate knowledge.

Key Numbers

505 GPs surveyed; 85.3% had patient inquiries; 52.3% comfortable discussing; 21.8% had prescribed; 66.9% felt inadequate knowledge. GPs rated opioids, benzodiazepines, and chemotherapy drugs as more hazardous than cannabis.

How They Did This

Cross-sectional study using a 42-item online questionnaire completed by 505 Australian GPs attending an educational seminar between November 2021 and February 2022. Results were compared to a 2017 survey to track changes over time.

Why This Research Matters

Six years after medicinal cannabis became available in Australia, GPs remain the primary prescribers but many feel underprepared, highlighting a gap between patient demand and practitioner readiness.

The Bigger Picture

The gap between patient interest and GP confidence in medicinal cannabis is a global pattern seen across multiple countries, suggesting systemic issues with medical education rather than country-specific barriers.

What This Study Doesn't Tell Us

GPs attending educational seminars may not represent all GPs. Self-selection bias likely. Some GPs incorrectly believed CBD causes addiction and driving impairment, suggesting misinformation. Cross-sectional design.

Questions This Raises

  • ?What specific educational interventions would most effectively improve GP knowledge?
  • ?Does GP comfort with cannabis prescribing correlate with patient outcomes?

Frequently Asked Questions

How has GP acceptance of medicinal cannabis changed since 2017?

Support for prescribing cannabis for palliative care, cancer pain, chemotherapy nausea, and epilepsy increased between 2017 and 2022. However, support for prescribing for mental health conditions like depression and anxiety remained lower.

What misconceptions did GPs hold about cannabis?

Some GPs incorrectly believed CBD (cannabidiol) could cause addiction and driving impairment, which does not align with current evidence. This suggests a need for better educational resources.
