Ethical Prescribing of Medical Cannabis: A Doctor’s Perspective
Understanding Medical Cannabis
Medical cannabis, also known as medicinal marijuana, is derived from the Cannabis sativa plant. Its primary active compounds, THC (tetrahydrocannabinol) and CBD (cannabidiol), interact with the body’s endocannabinoid system to regulate pain, inflammation, mood, and neurological function. While THC is psychoactive, CBD is non-psychoactive and widely studied for its therapeutic potential.
Doctors increasingly explore medical cannabis as a tool in healthcare for chronic pain, neurological disorders, mental health conditions, and supportive care in oncology.
Legal Status and Regulations: Focus on Australia and Beyond
In Australia, medical cannabis was legally recognised in 2016. The Therapeutic Goods Administration (TGA) regulates its use, requiring prescriptions from authorised healthcare providers. Patients may access cannabis for conditions such as chronic pain, epilepsy, anxiety, and chemotherapy-induced nausea. Licensed suppliers ensure products meet quality standards.
Globally, laws vary widely. Canada has a comprehensive medical cannabis program, while the U.S. has a patchwork of state-specific regulations. Israel and parts of Europe have established structured programs, often with research-driven protocols.

Medicinal Benefits and Applications
Medical cannabis demonstrates a broad range of benefits:
- Chronic Pain Management: Cannabinoids modulate pain pathways, helping patients with arthritis, neuropathy, or fibromyalgia.
- Neurological Conditions: CBD has shown efficacy in reducing seizures in epilepsy and improving spasticity in multiple sclerosis.
- Mental Health Support: Emerging research highlights potential relief for anxiety, PTSD, and depression.
- Oncology Care: Cannabis alleviates chemotherapy-induced nausea, stimulates appetite, and manages cancer-related pain.
Patient studies indicate improvements in sleep, mood, and overall quality of life, often reducing reliance on opioids and other conventional medications.
Potential Risks and Side Effects
While generally safe, medical cannabis carries potential risks:
- Common Side Effects: Fatigue, dry mouth, dizziness, and mild gastrointestinal issues.
- THC-Related Effects: Psychoactive effects such as anxiety, euphoria, or impaired motor function.
- Drug Interactions: Cannabis may interact with blood thinners, anti-seizure medications, or sedatives.
Responsible use and medical supervision are essential to minimize adverse outcomes.

Ethical Considerations in Prescribing
Doctors face important ethical responsibilities:
- Informed Consent: Patients must understand the benefits, risks, and alternatives.
- Personalized Treatment: Prescriptions should consider individual health profiles, conditions, and potential drug interactions.
- Monitoring and Follow-Up: Continuous assessment ensures efficacy, prevents misuse, and identifies adverse effects.
- Stigma Awareness: Healthcare providers must address societal misconceptions and ensure equitable access.
Ethical prescribing balances patient autonomy, clinical judgment, and societal responsibility.
Practical Guidelines for Responsible Use
Responsible medical cannabis use involves:
- Start Low and Go Slow: Begin with minimal doses, particularly with THC products.
- Track Effects: Document symptom relief, mood, and sleep patterns.
- Consistency: Use at regular intervals for maximum therapeutic benefit.
- Ongoing Communication: Regular check-ins with the prescribing physician are crucial.
These steps enhance safety, effectiveness, and patient empowerment.
Real-World Examples and Research
Recent Australian studies show patients with chronic pain who used CBD-dominant medical cannabis experienced improved daily functioning and reduced reliance on opioids over 12 weeks. Another study in mental health settings reported decreased anxiety and improved sleep in PTSD patients using tailored cannabinoid therapy.
These cases highlight the importance of individualized care, careful monitoring, and ethical oversight in prescribing practices.
Conclusion
Medical cannabis is increasingly recognized as a legitimate therapeutic option. Doctors must consider legal frameworks, medicinal benefits, potential risks, and ethical responsibilities when prescribing cannabis. By prioritizing patient education, responsible use, and personalized treatment, healthcare providers can integrate cannabis safely into modern medicine while fostering trust and improving patient outcomes.
