ALS (also known as Lou Gehrig’s Disease) is a fatal motor neuron disease, affecting an estimated 30,000 Americans.
ALS causes the degeneration of nerves that control voluntary muscle movement, like those that allow us to chew, speak, and walk. When the nerves die, they stop sending messages to the muscles which causes gradual weakening, twitching, and wasting away.
Patients with ALS become weak, but remain quite conscious. They are completely aware of their progressive disability. Eventually, the brain can no longer initiate or control voluntary movements. Death often results from respiratory failure when the nerves that control breathing lose the ability to function.
We don’t know what causes ALS. There is a genetic mutation that affects 5 to 10 percent of patients, but most cases are sporadic with no clear risk factors or family history of the disease. Athletes and those who have served in the military have a higher incidence of ALS, but we have not been able to find a clear causal connection for this observation. ALS is recognized as a service-connected disease by the U.S. Department of Veterans Affairs.
Conventional Treatment for ALS
There is no known cure for ALS. There are prescription medications approved by the FDA to treat the disease by reducing damage to nerves or by slowing the decline of function. These drugs may prolong life, but neither drug stops the disease in its tracks.
Other prescription medications are used to treat the symptoms of ALS. Muscle cramps, stiffness, and drooling are common, as are disturbing uncontrollable episodes of laughing or crying caused by destruction of brain tissue. Pain, depression, sleep problems and constipation may also be managed by medication, some more successfully than others.
Cannabinoids: Antioxidants and Neuroprotectants
Nerve damage in ALS is caused by two significant factors: oxidative stress and excitotoxicity. Cannabis shows promise as an aid in managing some of the nerve damage, as it has been shown to generally address both factors, though specific studies on ALS and cannabis have yet to be done.
Oxidative stress occurs when there is an imbalance between free radicals and antioxidants within the body. When the production of antioxidants can’t keep up with production of free radicals, we are not able to detoxify from the free radicals’ harmful effects in the body. Cannabis is a known antioxidant and helps to decrease the nerve tissue damage that free radicals can cause.
Excitotoxicity destroys nerve tissue that has already been compromised. When nerve tissue is injured, the amino acid glutamate is released in excessive, uncontrolled amounts. This excess leads to cell death, a destructive process called excitotoxicity. CBD and THC both decrease the release of glutamate, thus sparing the neurons from excitotoxity and cell death.

The Proof is in the Patents
These cannabinoid qualities are well-known and recognized as therapeutic. The US government filed Federal Patent #US 6630507 B1 in 1999 that specifically identifies cannabinoids as antioxidants and neuroprotectants:
“The cannabinoids are found to have particular application as neuroprotectants, for example in limiting neurological damage following ischemic insults, such as stroke and trauma, or in the treatment of neurodegenerative diseases…”
Considering the neuroprotective effects of cannabinoids and the anti-spastic effects of cannabinoids in multiple sclerosis patients, it only makes sense to consider their use in ALS. Preclinical work and some patient reports are promising.
What Research Exists?
Raman et al published a 2004 study that showed THC delays ALS progression in mice. Based on this and other compelling research data, Carter et al published a review in 2010 that called for clinical studies.
“Preclinical data indicate that cannabis has powerful antioxidative, anti-inflammatory, and neuroprotective effects. Cannabis also has properties applicable to symptom management of ALS, including analgesia, muscle relaxation, bronchodilation, saliva reduction, appetite stimulation, and sleep induction. With respect to the treatment of ALS, from both a disease modifying and symptom management viewpoint, clinical trials with cannabis are the next logical step. Based on the currently available scientific data, it is reasonable to think that cannabis might significantly slow the progression of ALS, potentially extending life expectancy and substantially reducing the overall burden of the disease.”
Managing ALS With Cannabis
THC and CBD are considered the most helpful phytocannabinoids for patients with ALS. Any clinical feedback ALS patients provide on the use and effectiveness of cannabinoid medicine will encourage further research and the publication of well-designed clinical studies.
