Arthritis and inflammation

Understanding arthritis and inflammation

Arthritis covers conditions causing joint pain, stiffness and inflammation, such as osteoarthritis or rheumatoid arthritis. Management relies first on appropriate medication, physical activity and medical follow-up.

Medical cannabis and arthritis and inflammation

Medical cannabis is sometimes considered within a plan to manage arthritis-related pain when other options haven't been enough. It is not a treatment for arthritis itself, nor a substitute for your medical follow-up. A practitioner assesses your situation, medications and any precautions that apply.

What the evidence shows

Recent osteoarthritis reviews found a small number of highly varied studies. Some report pain improvement, but evidence on function and safety is incomplete and the overall certainty remains limited.

What it does not establish

There is no strong evidence that cannabis slows osteoarthritis, protects joints or controls an inflammatory disease such as rheumatoid arthritis. It does not replace disease-modifying treatment.

Points to discuss during the assessment

• The exact type of arthritis and specialist follow-up
• Pain at rest compared with pain during movement
• Mobility and activities you want to preserve
• Current anti-inflammatory drugs, blood thinners and other medications

Important precautions

• Adverse effects can include drowsiness, dizziness, impaired attention, anxiety or a faster heart rate.
• THC can impair driving and the operation of machinery; never drive while impaired.
• Particular caution is required during pregnancy or breastfeeding, with some heart conditions, or with a personal or family history of psychosis.
• Tell the practitioner about all current medications and supplements so possible interactions can be assessed.
