Breathing Easier with Cannabis: ALS Patients Finding Relief

Amyotrophic Lateral Sclerosis (ALS), also known as Lou Gehrig’s disease, is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord, leading to loss of muscle control. One of the more serious complications of ALS is difficulty with breathing, as the muscles that aid in respiration weaken. Recently, there has been growing interest in the potential benefits of cannabis for ALS patients, particularly regarding respiratory function.

The Respiratory Challenge in ALS

As ALS progresses, patients may experience respiratory failure, which is the most common cause of death for those with the disease. The loss of respiratory muscle strength hampers the ability to cough, clear airways, and can lead to decreased lung function, making breathing laborious.

Cannabis and Neuroprotection

Cannabis contains compounds that may offer neuroprotective effects, which could be beneficial in diseases like ALS that involve neural degeneration. Cannabinoids such as THC and CBD are known to interact with the endocannabinoid system, which plays a role in the regulation of various physiological processes including inflammation and nerve health.

Potential Benefits for Respiration

Research on cannabis and ALS is still in its early stages, but some studies suggest that cannabinoids may help in managing symptoms related to respiratory function. A study in the “American Journal of Hospice and Palliative Care” suggested that cannabis might have a range of pharmacological effects that could be beneficial for ALS patients, including bronchodilation (Carter et al., 2010).

Bronchodilation, the widening of the bronchi and bronchioles, can aid in better air movement, potentially offering relief to patients experiencing breathing difficulties. Although traditionally associated with the treatment of asthma, bronchodilation might assist ALS patients by easing the work of breathing.

Improved Sleep and Reduced Spasticity

Sleep disturbances due to difficulty breathing can significantly affect life quality in ALS patients. Cannabinoids have been recognized for their sedative effects and might improve sleep quality for those with respiratory difficulties. Furthermore, cannabis has been found to reduce spasticity — involuntary muscle contractions — which is a common symptom of ALS and can further interfere with normal breathing.

Anecdotal Evidence

There is anecdotal evidence from patients with ALS who have used cannabis that suggests a subjective improvement in respiratory function and overall well-being. These reports are valuable as they offer insights into the potential relief cannabis could provide, underscoring the need for more structured clinical research.

Considerations for Use

While the potential benefits of cannabis for ALS patients are promising, it is crucial to consult with healthcare providers before use. Dosage, method of consumption, and the balance of THC and CBD should be tailored to individual needs and symptoms under professional guidance. Vaporizing cannabis, for example, may deliver the beneficial effects without the potential harm of smoke inhalation.

Legal and Ethical Aspects

The legal status of cannabis varies widely, and this affects the availability for patients. As research progresses and laws potentially change, the therapeutic use of cannabis in ALS, particularly for respiratory issues, may become a more accessible and discussed option in patient care.


For ALS patients grappling with the daunting challenge of respiratory complications, cannabis may offer a source of relief. While we await more comprehensive research, the neuroprotective and bronchodilatory effects of cannabis, along with its ability to reduce spasticity and improve sleep, suggest a potential role in supporting respiratory health in ALS.

Please note, the use of cannabis should always be discussed with a healthcare professional and should be in compliance with local regulations.
