[Therapeutic use of cannabis derivatives].

The therapeutic use of cannabis has generated a lot of interest in the past years, leading to a better understanding of its mechanisms of action. Countries like the United States and Canada have modified their laws in order to make cannabinoid use legal in the medical context. It’s also the case in France now, where a recent decree was issued, authorizing the prescription of medication containing “therapeutic cannabis” (decree no. 2013-473, June 5, 2013). These agents are most promising to relieve chronic pain associated with cancer, with human immunodeficiency virus infection and with multiple sclerosis.

Clinical endocannabinoid deficiency (CECD) revisited: can this concept explain the therapeutic benefits of cannabis in migraine, fibromyalgia, irritable bowel syndrome and other treatment-resistant conditions?

A review of the literature indicates that significant progress has been made since Dr. Ethan B. Russo’s landmark paper, just ten years ago (February 2, 2004). Investigation at that time suggested that cannabinoids can block spinal, peripheral and gastrointestional mechanisms that promote pain in headache, fibromyalgia, irritable bowel syndrome and muscle spasm. Further research and especially, clinical trials will further demonstrate the usefulness of medical cannabis. As legal barriers fall and scientific bias fades this will become more apparent.

Medical cannabis: Another piece in the mosaic of autoimmunity?

Legalization of cannabis’ medicinal use is rapidly increasing worldwide, raising the need to evaluate medical implications of cannabis. Currently, evidence supports cannabis and its active ingredients as immune-modulating agents, affecting T-cells, B-cells, monocytes, and microglia cells, causing an overall reduction in pro-inflammatory cytokine expression and an increase in anti-inflammatory cytokines. Due to the supporting evidence of cannabinoids as an immune-modulating agent, research focusing on cannabinoids and autoimmunity has emerged. Several clinical trials in multiple sclerosis, inflammatory bowel disease, and fibromyalgia suggest cannabis’ effectiveness as an immune-modulator.

Cannabis as a substitute for prescription drugs – a cross-sectional study

The use of medical cannabis is increasing, most commonly for pain, anxiety and depression. Emerging data suggest that use and abuse of prescription drugs may be decreasing in states where medical cannabis is legal. These patient-reported outcomes support prior research that individuals are using cannabis as a substitute for prescription drugs, particularly, narcotics/opioids, and independent of whether they identify themselves as medical or non-medical users. This is especially true if they suffer from pain, anxiety and depression. Additionally, this study suggests that state laws allowing access to, and use of, medical cannabis may not be influencing individual decision-making in this area.

Cannabis as a Substitute for Opioid-Based Pain Medication: Patient Self-Report

 Prescription drug overdoses are the leading cause of accidental death in the United States. Alternatives to opioids for the treatment of pain are necessary to address this issue. Cannabis can be an effective treatment for pain, greatly reduces the chance of dependence, and eliminates the risk of fatal overdose compared to opioid-based medications. Medical cannabis patients report that cannabis is just as effective, if not more, than opioid-based medications for pain. 

Brief Report: Cannabidiol-Rich Cannabis in Children with Autism Spectrum Disorder and Severe Behavioral Problems-A Retrospective Feasibility Study

Anecdotal evidence of successful cannabis treatment in autism spectrum disorder (ASD) are accumulating but clinical studies are lacking. Following the cannabis treatment, behavioral outbreaks were much improved or very much improved in 61% of patients. This preliminary study supports feasibility of CBD-based cannabis trials in children with ASD.
