Navigating MS: The Emerging Role of Medicinal Cannabis in Symptom Management

What is Multiple Sclerosis?

Multiple sclerosis (MS) is a long-term health condition affecting the brain and spinal cord. In MS, the protective layer (known as the myelin sheath) that covers our nerves gets inflamed and damaged. This damage disrupts the normal communication between our brain and the rest of the body. Over 4,000 New Zealanders live with MS, a condition that can impact movement, sensation, balance, bodily functions, and cognition.

Who is Affected and What Causes MS?

MS is typically diagnosed between the ages of 20 and 50, with women being three times more likely to be affected than men. The exact cause of MS is still unknown, but it involves a combination of genetic and environmental factors. MS is considered an autoimmune condition, where the body’s immune system mistakenly attacks its own cells.

Understanding MS Symptoms

Symptoms of MS vary and relate to the affected nerve areas. Common symptoms include muscle spasm and stiffness, pain, visual disturbances, fatigue, numbness, weakness in limbs, balance problems, tremor, dizziness, bladder and bowel issues, and cognitive difficulties.

Multiple Sclerosis Treatment with Medicinal Cannabis

Medicinal Cannabis and MS in New Zealand

Medicinal cannabis was approved in New Zealand in 2010 for treating certain MS symptoms, particularly muscle pain and stiffness. It involves a combination of CBD and THC, and its effectiveness varies among individuals. A slow and low approach is recommended to find the lowest effective dose and minimise side effects. While some people experience significant improvements, others may see moderate or minimal changes.

Other Symptoms Addressed by Medicinal Cannabis

Evidence suggests medicinal cannabis may also help with MS-related pain, sleep issues, and anxiety. It’s often used alongside other treatments and may reduce the need for certain pain relievers or sedatives.

Important Considerations

It’s crucial to remember that medicinal cannabis does not impact the underlying MS disease process. Its role is to manage symptoms and improve quality of life. Treatment should be supervised by a practitioner experienced in prescribing medicinal cannabis, and it’s often safe to use with conventional MS medications, with some exceptions.


At CannaPlus+, we are committed to providing up-to-date, evidence-based information about MS and medicinal cannabis treatment. We encourage patients to discuss their treatment options with their healthcare providers, ensuring a safe and effective approach to managing their condition.



Q1: What is Multiple Sclerosis (MS)?

    • Tremor
    • Dizziness
    • Bladder and bowel concerns
    • Anxiety/depression
    • Difficulty with thinking

Q3: How is MS diagnosed?

A: MS is diagnosed by a neurologist through a combination of medical history, physical exams, and tests like MRI scans, which help to look at the brain and spinal cord.

Q4: Can medicinal cannabis help with MS?

A: Yes, medicinal cannabis, particularly combinations of CBD and THC, has been found to be helpful in managing symptoms like muscle stiffness and pain associated with MS.

Q5: Is medicinal cannabis safe for everyone with MS?

A: While it can be beneficial, medicinal cannabis may not be suitable for everyone. It’s important to consult with a healthcare professional experienced in prescribing medicinal cannabis to ensure safety and effectiveness.

Q6: How is medicinal cannabis used in MS treatment?

A: Medicinal cannabis is often used as part of a broader treatment plan. It’s usually started at a low dose and gradually increased to find the most effective dose with minimal side effects.

Q7: Does medicinal cannabis cure MS?

A: No, medicinal cannabis does not cure MS. It is used to help manage symptoms and improve the quality of life for people living with MS.
