MedlinePlus, the National Library of Medicine's online Medical Encyclopedia, stated as of May 15, 2006:
"Arthritis is inflammation of one or more joints, which results in pain, swelling, and limited movement.
Osteoarthritis is a common type
of arthritis characterized by a gradual loss of cartilage from the
joints. Although osteoarthritis can affect almost any joint, it most
often affects the hands, knees, hips, and spine. Common symptoms
include pain, stiffness, some loss of joint motion, and changes in the
shape of affected joints.
Rheumatoid arthritis is a chronic
autoimmune disease, mainly characterized by inflammation of the lining,
or synovium, of the joints. It can lead to long-term joint damage,
resulting in chronic pain, loss of function and disability"
Is Marijuana an Effective Treatment for the Symptoms of Arthritis?
Rheumatology reported in a Jan. 2006 article titled "Preliminary Assessment of The Efficacy, Tolerability and Safety of A Cannabis-based Medicine (Sativex) in The Treatment of Pain Caused By Rheumatoid Arthritis," by D.R. Blake et al.:
"In comparison with placebo, the CBM [cannabis-based medicine]
produced statistically significant improvements in pain on movement, pain at rest, quality of sleep....
In the first ever controlled trial of a CBM
in RA [rheumatoid arthritis], a significant analgesic effect was
observed and disease activity was significantly suppressed
following Sativex treatment."
The Journal of Neuroimmunology, in their Sep. 2005 article titled "Cannabinoids and the Immune System: Potential For The Treatment of Inflammatory Diseases?" by J. Ludovic and Takashi Yamamura, stated:
from chronic cannabis smokers have provided much of the evidence for
immunomodulatory [modifying or regulating the immune system] effects of
cannabis in humans...
can modulate both the function and secretion of cytokines
[regulatory proteins] from immune cells.
Therefore, cannabinoids may be considered for treatment of inflammatory disease."
Ethan Russo, MD, Senior Medical Advisor at the Cannabinoid Research Institute, stated in a 2005 Americans for Safe Access brochure titled "Arthritis and Medical Marijuana":
"Patients have long told us that cannabis has
been helpful to them in the treatment of their arthritic
Science has now demonstrated that the THC component of cannabis is a
very effective analgesic (pain killer), and that the CBD (cannabidiol)
component has unique immunomodulatory benefits as an antagonist of
tumor necrosis factor-alpha, supporting benefits in treatment of
Tod Mikuriya, MD, a psychiatrist and medical coordinator, stated in the 2002 article titled "Medicinal Uses of Cannabis," published on his website:
"Clinical interviews of
over 6500 members at cannabis buyers clubs and patients in my
office practice lead to this generalization: Many illnesses or
conditions present with both inflammation and muscle spasm.
Cannabis is both an antispasmodic and anti inflammatory....
Chronic inflammatory conditions like arthritis and lumbosacral disease
responds well to cannabis compared with other analgesics.

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."
James McKoy, MD, Chief of Rheumatology at Kaiser Permanente in Honolulu, Hawaii, stated in the Dec. 2000 issue of Arthritis Today:
"I have one patient with
rheumatoid arthritis who uses it for pain and, other than getting
a 'high,' it hasn't reduced any of her needs for DMARDs
[disease-modifying antirheumatic drugs], NSAIDs [non- steroidal
anti inflammatory drugs], prednisone or Vicodin.
The National Institute of Drug Abuse (NIDA), in its July 2005 "Research Report," stated:
is underway to examine the effects of smoked marijuana and extracts of
marijuana on appetite stimulation, certain types of pain [including
arthritis], and spasticity due to multiple sclerosis. However, the
inconsistency of THC dosage in different marijuana samples poses a
major hindrance to valid trials and to the safe and effective use of
little is known about the many chemicals besides THC that are in
marijuana, or their possible deleterious impact on patients with
The Office of National Drug Control Policy (UNDCP) Director John Walters stated in an Apr. 21, 2006 press release:
"Too many of our citizens
suffer from pain [a symptom of arthritis] and chronic illnesses.
Smoking illegal drugs may make some people
'feel better.' However, civilized societies and modern day
medical practices differentiate between inebriation and the
safe, supervised delivery of proven medicine by legitimate
