Can Cannabis Provide New Hope for Chronic Pain Sufferers?

For millions worldwide, chronic pain is a daily reality.  This has, unfortunately, led to an overuse of strategies reliant upon addictive and dangerous drug families like opioids.  This has led to a search for safer and more effective alternatives, with cannabis emerging at the forefront in many cases.  The plant, which has a long history of medicinal use, is increasingly being seen as a potential tool in the fight against chronic pain for sufferers in need of something less potent and less dangerous than an opioid.  This is recently highlighted in a study under the title ‘Cannabis-dependent analgesia is mediated by hypothalamic galanin‘¹.

Cannabis’s Pain-Relieving Potential

In the aforementioned study, researchers found that the analgesic effects of cannabis are mediated through a specific pathway in the brain involving the neuropeptide galanin, primarily in the hypothalamus. Simply put – when galanin was released in the hypothalamus in the presence of cannabinoids, pain responses were less pronounced.  This is important because it tells us how and where cannabis works to diminish pain, potentially allowing for targeted drug development.

However, it is important to note that while the study highlighted the role of the hypothalamus and galanin in pain responses, cannabis’s pain-relieving effects are still believed to be multi-pronged.  Previous research² has established interactions between THC and CBD with the endocannabinoid system (ECS), which also has the ability to not only regulate pain but also reduce inflammation and other physiological processes.

A Solution to the Opioid Crisis?

The opioid crisis is far greater than anything one alternative medication can tackle.  However, cannabis as a pain reliever is particularly intriguing, as it has the potential to prevent many individuals from becoming dependent on an addictive drug class that may be too potent for their needs in the first place.

For the time being, as we previously highlighted,  there is a significant disconnect between chronic pain sufferers and their doctors.  Patients often feel their pain is not adequately addressed while doctors grapple with the risks associated with opioid prescriptions.  These two common options equate to choosing between undermedicating or overmedicating a patient.  Cannabis could be the answer to getting it just right with its pain-relieving properties, coupled with a lower risk of addiction compared to opioids, making it an attractive alternative for managing chronic pain.

For those worried that cannabis will simply lead to opioids in time anyway, make sure to read another of our recent articles in which we highlighted a study that shed light on how cannabis is no longer viewed as a gateway drug.  Notably, it was found that cannabis use could actually lead to a reduction in opioid reliance among chronic pain patients.  This is a crucial point because the misconception that cannabis use leads to harder drug use has historically been a barrier to its acceptance as a legitimate medicine.

Time for a Change?

As legalization and mainstream acceptance of cannabis continue to spread, so does our understanding of the plant and its medicinal properties through stringent studies.  While more time and work may be needed to definitively slot cannabis in as a potential alternative to opioids, the growing body of evidence supporting this is strong.  For now, cannabis stands at a pivotal point in its growth from a stigmatized substance to a recognized medicine.
