J. Michael Walker, PhD, Professor of Psychology and the Linda and Jack Gill Chair of Neuroscience at the University of Indiana, in the Dec. 2000 issue of Arthritis Today, stated:

“The spinal cord is loaded with cannabinoid receptors. These cannabinoid compounds [from marijuana] apparently reduce swelling from inflammation [a major symptom of arthritis]. But more than that, they kill the pain from inflammation specifically. They work on the peripheral nerves that carry pain from your joint into the spinal cord.”
