Therapeutic Action of Cannabinoids on Multiple Sclerosis

Multiple sclerosis (MS) is a chronic progressive neuro-degenerative disease where the brain and spinal cord are damaged by the gradual destruction of myelin, which is the tissue that covers and protects the brain and spinal cord. Patients who have MS suffer with painful muscle spasms, numbness, impaired vision, loss of balance and coordination, tremors, and weakness. There is currently no known cure for MS.

That being said... DELTA..sup.9-Tetrahydrocannabinol (.DELTA..sup.9-THC), the major psychoactive constituent of marijuana, exerts a broad range of therapeutic effects through its interactions with two cannabinoid (CB) receptor subtypes, CB.sub.1 and CB.sub.2. CB.sub.1 receptors are highly expressed in the central nervous system and to a lesser degree in the periphery in a variety of tissues of the cardiovascular and gastrointestinal systems. By contrast, CB.sub.2 receptors are most abundantly expressed in multiple lymphoid organs and cells of the immune system, including spleen, thymus, tonsils, bone marrow, pancreas and mast cells.

Many MS patients are using medical marijuana as they have found that it relieves the spasticity, calms tremors, and helps with the depression and anxiety of being ill. There are a number of scientific studies that show that marijuana helps to reduce MS symptoms. One study looked at 167 patients who reported less pain, less muscle spasms, and less bladder incontinence with use of cannabis. These patients reported that they were able to control symptoms with the same dose of cannabis for a mean duration of 434 days without having to increase their dose. (Wade, Multiple Sclerosis 10:425-33, 2004) Researchers suggest that this study demonstrates that marijuana does not lead to increased tolerance requiring increased doses of medication, unlike the conventional medications used to treat MS

Managing the spectrum of pain etiologies remains a major public health problem and both patients and clinicians are seeking improved strategies to effectively manage pain. No currently available therapies or drugs effectively treat all types of nociceptive and neuropathic pain states. The compounds of the present invention are novel CB.sub.2 receptor modulators that have utility in treating pain, including nociceptive and neuropathic pain.


  1. Sounds great but what about those of us that have asthma on top of MS and can't smoke stuff? I'm all about natural options though and wanna look into this more. I wonder if TX allows medical marijuana?

    A: Many medical marijuana patients are happy to learn about tinctures of cannabis. A tincture is an alcohol-based liquid mixture. It is like a concentrated extract. Currently there are tinctures of cannabis made with alcohol, oil or glycerin. It is a very effective way to use medical cannabis. Drops of the tincture are placed under the tongue (sublingually) and the medication passes through the blood vessels and enters the bloodstream. You will feel the onset of effects in about 5 – 15 minutes with the peak effect at about 30 minutes after taking the medication. For many patients, the effects are similar to inhaled cannabis.

    It is interesting to note that tinctures of cannabis were widely available around the mid 1800’s. -OR- Edibles take from 40 minutes to 1 hour to start working and the peak effect is at 2 hours. The effects last from 6 to 8 hours which is very convenient for those patients who want to sleep or have longer control of pain.
