The utilization of medical marijuana for chronic pain management has been a subject of extensive research and discussion within the medical community. Studies have shown that oral cannabis extracts and THC may be effective in treating centrally mediated pain and painful spasms. This is supported by evidence from multiple trials, indicating a potential role for cannabinoids in alleviating discomfort associated with various conditions.
In the context of spasticity, which often accompanies chronic pain, cannabinoids have been rated as effective based on patient-reported outcomes. However, the effectiveness on objective measures of spasticity is still considered to be only possibly effective. The distinction between subjective relief and objective measures is crucial for healthcare providers when considering treatment options.
While the evidence points towards a beneficial impact of cannabinoids on chronic pain, it is essential to approach this treatment option with careful consideration of individual patient circumstances and potential side effects.
The reluctance of clinicians to code for opioid use disorder highlights the need for comprehensive documentation and a multidisciplinary approach to pain management. This includes considering alternatives like cannabinoids, especially in light of the opioid crisis and the search for safer pain management strategies.
Spasticity and Neurological Benefits
Medical marijuana has been scrutinized for its potential benefits in treating spasticity and other neurological conditions. Evidence suggests that oral cannabis extract and THC may improve the subjective experience of spasticity, with several studies rating them as effective or probably effective. This is particularly relevant for conditions like multiple sclerosis, where spastic movements and pain are common symptoms.
The American Academy of Neurology, in a systematic review, found evidence supporting the effectiveness of cannabis extracts in treating certain neurological symptoms. However, it also noted that there is insufficient evidence to determine effectiveness for several other neurological diseases. The review highlighted the need for more high-quality trials to better understand the therapeutic potential and safety of medical marijuana in this context.
While medical marijuana shows promise in managing spasticity, it is crucial to consider the balance between therapeutic effects and potential adverse events.

The complexity of assessing impairment from cannabis use complicates the enforcement of safety regulations and underscores the need for clear guidelines and testing methods.
Efforts to address these concerns include the development of roadside testing technologies and workplace policies that balance patient rights with public safety. However, the variability in how individuals are affected by cannabis complicates these measures.
Cannabinoid Hyperemesis Syndrome
Cannabinoid Hyperemesis Syndrome (CHS) is a paradoxical condition where individuals who consume cannabis chronically and in large amounts experience severe nausea, vomiting, and abdominal pain. The syndrome is often characterized by a compulsion to take hot showers or baths, which can provide temporary relief from symptoms.
- Symptoms of CHS:
- Cyclic episodes of nausea and vomiting
- Abdominal pain
- Compulsive hot bathing
- Relief of symptoms with cessation of cannabis use
CHS is a relatively new clinical diagnosis, and its pathophysiology is not fully understood. However, it is believed to be associated with the dysregulation of the endocannabinoid system due to prolonged exposure to THC.
The condition is often under-recognized and may lead to frequent emergency department visits. Treatment primarily involves cessation of cannabis use, supportive care, and in some cases, pharmacological interventions. The recognition of CHS is crucial for appropriate management and prevention of unnecessary medical investigations and treatments.
Medical Cannabis Research Limitations
The intricate legal status of cannabis, particularly THC, has led to significant barriers in the availability of research material and funding. In the United States, the National Institute on Drug Abuse and the Drug Enforcement Administration maintain strict control over the only federally-legal cannabis source for research. Despite promises to issue licenses to additional growers, the reality has been a standstill, with no licenses granted out of numerous applications.
Federal limitations extend beyond cultivation to the clinical research and therapeutic applications of cannabis. The absence of FDA-approved cannabis products for federal commerce stifles the potential for comprehensive studies and the development of new treatments. This regulatory environment not only hampers the progress of medical marijuana research but also impacts the ability to draw reliable conclusions about its efficacy for various conditions.
