Pain

There is scientific evidence that cannabis possesses pain relieving qualities, and some research evidence to support the use of cannabinoids for this purpose. The House of Lords Science and Technology Committee note that it's analgesic effects justified rescheduling the drug so that doctors could legally prescribe it. They consider that priority should be given to further research in this area, as it is the most common symptom for which patients seek therapeutic relief. Similarly The British Medical Association (BMA) says "The prescription of Nabilone, THC and other cannabinoids should be permitted for patients with intractable pain", especially in terminal illness.

Some results suggest that pain caused by damaged nerves (neuropathic) might respond to cannabinoids. This could be of significant value as this type of pain is often resistant to standard opioids. An example is phantom limb pain following amputation (up to 30% of amputees suffer from this condition).

Cannabis may also offer fewer adverse effects than opiates (which can be highly addictive), and NSAIDS (Non-Steroidal Anti Inflammatory Drugs) such as Aspirin, Ibuprofen and Diclofenac, which can induce stomach ulcers, bleeding, and kidney failure.

Doctors commonly prescribe NSAIDs to ease the pain and inflammation associated with arthritis. Although pain-reducing properties of cannabis are well documented, evidence is emerging indicating that it may also hold anti-inflammatory qualities useful in both types of arthritis. It is feasible that these properties could reduce swelling and improve mobility in some arthritis patients.

Physicians are also showing interest in examining the potential of cannabis to treat pain caused by symptoms of migraine, spinal cord injury, fibromyalgia & Nail Patella Syndrome.
