The Endocannabinoid System — Clinical Relevance

While well-known systems like the sympathetic nervous system are widely understood, doctors may be less familiar with the more recently identified endocannabinoid system (ECS).^1,2 The ECS is thought to be involved in regulating pain, immunity, stress, appetite, weight, and nausea, yet it remains largely absent from traditional medical education in Australia.³

What will you learn?
This module aims to equip you with the skills and confidence to integrate medical cannabis into patient care when clinically appropriate. Drawing on current evidence and theoretical case studies, the module explores the ECS, cannabinoid pharmacology, proposed therapeutic effects, and the clinical implications of both ECS function and use of medical cannabis.

Through interactive scenarios and evidence summaries, you’ll explore how this knowledge may be relevant to clinical applications—ranging from the potential involvement of the ECS in patient presentations to identifying possible treatment approaches.

Estimated Duration: 4 hours

Access Duration: 12 months from date of purchase

Learning Outcomes

Upon completion of this module, you’ll be able to:

• Identify the endocannabinoid system’s components, role and functions, as currently understood
• Describe how endocannabinoid system function and dysfunction may contribute to symptoms such as pain, anxiety, sleep disturbance and inflammation
• Interpret how the mechanism of the endocannabinoid system may inform the therapeutic potential of medical cannabis
• Explain the pharmacological effects of THC and CBD
• Identify clinical features suggestive of cannabinoid tolerance or receptor desensitisation
• Describe the limitations and uncertainties in the current evidence relating to the endocannabinoid system
