SCIs are thought to affect between 10.4 and 83 people per million every year. In North America, about 39 in every million people incur a traumatic SCI each year. Falls and other high impact injuries are common causes of SCIs, but people with arthritis or multiple sclerosis (MS) are also at high risk of SCIs.

Spinal cord diseases (SCDs) can include degenerative disc disease (DDD), Spinocerebellar Ataxia (SCA), spinal stenosis, tumors affecting the spine, and many more. Activation of CB1 receptors is associated with deficits in motor coordination, whereas CB1 receptor antagonists may help prevent and overcome such deficits, restoring balance to the ECS and (quite literally) balance to the body and one’s ability to move.

There are a number of endocannabinoid receptors on the spinal cord. Targeting these could help prevent further cell damage. CBD may help repair broken, fractured and porous bones, as the ECS has been shown to play a role in the regulation of bone metabolism and the formation of bones.

Frequently asked questions

Is a spinal cord injury a qualifying condition for medical cannabis?

Yes — spinal cord injuries and diseases are explicitly listed qualifying conditions in the majority of U.S. medical cannabis states. The evidence base for cannabis in SCI-related pain, spasticity, and neurological symptoms is well-established.

How does medical cannabis help with spinal cord injury symptoms?

Medical cannabis is used to manage several SCI-related challenges, including neuropathic pain below the level of injury, muscle spasticity, bladder dysfunction, sleep disorders, and depression. It can also help with central sensitization — the heightened pain response common in SCI patients.

Can cannabis restore function after a spinal cord injury?

There is no evidence that cannabis can restore lost function in spinal cord injuries. Its role is in symptom management and quality-of-life improvement. Preclinical research into cannabinoids' neuroprotective and anti-inflammatory properties is ongoing, but human trials have not yet shown functional recovery.

What delivery method is best for SCI patients?

Because motor function may be limited, easy-to-use delivery methods are preferred. Capsules, tinctures, and edibles are most accessible for SCI patients. Topicals can provide localized relief for muscle spasms and pain without systemic effects. A Leafwell provider will factor in your level of injury and mobility when making recommendations.

Does Leafwell offer online consultations for SCI patients who have mobility challenges?

Yes — Leafwell's entire consultation process is conducted online, from any device, from your home. No in-person appointment is needed. The process is designed to be as accessible as possible for patients with mobility limitations.
