“Inflammatory bowel diseases (IBD) are disorders of chronic intestinal inflammation of unknown etiology. The basic pathophysiological process is that of immune mediated inflammation affecting the intestinal tract. This process is dependent on and governed by both genetic and environmental factors. There are two distinct forms of IBD – ulcerative colitis and Crohn’s disease. There is no curative medical treatment. Furthermore, over 30% of patients, and over 70% with Crohn’s disease, will need surgical intervention for their disease. Thus, it comes as no surprise that many patients will turn to complementary or alternative medicine at some stage of their disease. Recent information reveals that between 16% and 50% of patients admit to having tried marijuana for their symptoms. There is a long list of gastrointestinal symptoms that have been reported to be relieved by cannabis. These include anorexia, nausea, abdominal pain, diarrhea, gastroparesis – all of which can be part of IBD. These effects are related to the fact that the gastrointestinal tract is rich in cannabinoid (CB) receptors and their endogenous ligands, comprising together the endocannabinoid system (ECS). In conclusion, use of cannabis is common in IBD, and it seems to be mostly safe. Accumulating preliminary data from human studies support a beneficial role of cannabinoids in IBD.” https://www.ima.org.il/FilesUpload/IMAJ/0/228/114217.pdf https://www.ima.org.il/imaj/ViewArticle.aspx?aId=4045 https://www.ncbi.nlm.nih.gov/pubmed/28457058]]>

Efficacy of Medical Cannabis for Treatment of Refractory Epilepsy in Children and Adolescents with Emphasis on the Israeli Experience.
“The effectiveness of marijuana in the treatment of epilepsy was originally reported as early as 1800 BC. There is now concrete evidence to suggest the efficacy of cannabis in the treatment of epilepsy, particularly in the refractory group. To summarize, in view of the good outcome in a significant number of patients, which is not significantly worse than other accepted options for patients with refractory epilepsy, it seems that medical cannabis should be considered a viable treatment option.” https://www.ima.org.il/FilesUpload/IMAJ/0/228/114213.pdf https://www.ima.org.il/imaj/ViewArticle.aspx?aId=4041 https://www.ncbi.nlm.nih.gov/pubmed/28457054]]>
The role of cannabinoids in dermatology
“Twenty-eight states currently allow for comprehensive public medical cannabis programs, and this number continues to grow. Approximately 1 in 10 adult cannabis users in the United States use it for medical purposes. Numerous studies have investigated its uses for chronic pain, spasticity, anorexia, and nausea. In recent years, researchers have also investigated its use for the treatment of dermatologic conditions including pruritus, inflammatory skin disease, and skin cancer.” http://www.jaad.org/article/S0190-9622(17)30308-0/abstract]]>
Neurological aspects of medical use of cannabidiol.
“Cannabidiol (CBD) is among the major secondary metabolites of Cannabis devoid of the delta-9-tetra-hydrocannabinol psychoactive effects. It is a resorcinol-based compound with a broad spectrum of potential therapeutic properties, including neuroprotective effects in numerous pathological conditions. CBD neuroprotection is due to its antioxidant and antiinflammatory activi-ties and the modulation of a large number of brain biological targets (receptors, channels) involved in the development and maintenance of neurodegenerative diseases.
OBJECTIVE:
Aim of the present review was to describe the state of art about the pre-clinical research, the potential use and, when existing, the clinical evidence related to CBD in the neurological field.RESULTS:
Laboratory and clinical studies on the potential role of CBD in Parkinson’s disease (PD), Alzheimer’s disease (AD), multiple sclerosis (MS), Huntington’s disease (HD), amyotrophic lateral sclerosis ALS), cerebral ischemia, were examined.CONCLUSIONS:
Pre-clinical evidence largely shows that CBD can produce beneficial effects in AD, PD and MS patients, but its employment for these disorders needs further confirmation from well designed clinical studies. CBD pre-clinical demonstration of antiepileptic activity is supported by recent clinical studies in human epileptic subjects resistant to standard antiepileptic drugs showing its potential use in children and young adults affected by refractory epilepsy. Evidence for use of CBD in PD is still not supported by sufficient data whereas only a few studies including a small number of patients are available.” https://www.ncbi.nlm.nih.gov/pubmed/28412918]]>Cannabis for Pain and Headaches: Primer.
“Marijuana has been used both medicinally and recreationally since ancient times and interest in its compounds for pain relief has increased in recent years. The identification of our own intrinsic, endocannabinoid system has laid the foundation for further research. Synthetic cannabinoids are being developed and synthesized from the marijuana plant such as dronabinol and nabilone. The US Food and Drug Administration approved the use of dronabinol and nabilone for chemotherapy-associated nausea and vomiting and HIV (Human Immunodeficiency Virus) wasting. Nabiximols is a cannabis extract that is approved for the treatment of spasticity and intractable pain in Canada and the UK. Further clinical trials are studying the effect of marijuana extracts for seizure disorders. Phytocannabinoids have been identified as key compounds involved in analgesia and anti-inflammatory effects. Other compounds found in cannabis such as flavonoids and terpenes are also being investigated as to their individual or synergistic effects. This article will review relevant literature regarding medical use of marijuana and cannabinoid pharmaceuticals with an emphasis on pain and headaches.” https://www.ncbi.nlm.nih.gov/pubmed/28281107]]>
Cannabinoids for treating inflammatory bowel diseases: where are we and where do we go?
“Fifty years after the discovery of Δ9-tetrahydrocannabinol (THC) as the psychoactive component of Cannabis, we are assessing the possibility of translating this herb into clinical treatment of inflammatory bowel diseases (IBDs).
Here, a discussion on the problems associated with a potential treatment is given.
From first surveys and small clinical studies in patients with IBD we have learned that Cannabis is frequently used to alleviate diarrhea, abdominal pain, and loss of appetite.
Single ingredients from Cannabis, such as THC and cannabidiol, commonly described as cannabinoids, are responsible for these effects. Synthetic cannabinoid receptor agonists are also termed cannabinoids, some of which, like dronabinol and nabilone, are already available with a narcotic prescription.
Recent data on the effects of Cannabis/cannabinoids in experimental models of IBD and in clinical trials with IBD patients have been reviewed using a PubMed database search. A short background on the endocannabinoid system is also provided.
Expert commentary: Cannabinoids could be helpful for certain symptoms of IBD, but there is still a lack of clinical studies to prove efficacy, tolerability and safety of cannabinoid-based medication for IBD patients, leaving medical professionals without evidence and guidelines.”
Potential of Cannabidiol for the Treatment of Viral Hepatitis.
“Viral hepatitis B (HBV) and hepatitis C (HCV) pose a major health problem globally and if untreated, both viruses lead to severe liver damage resulting in liver cirrhosis and cancer. While HBV has a vaccine, HCV has none at the moment. The risk of drug resistance, combined with the high cost of current therapies, makes it a necessity for cost-effective therapeutics to be discovered and developed. The recent surge in interest in Medical Cannabis has led to interest in evaluating and validating the therapeutic potentials of Cannabis and its metabolites against various diseases including viruses. Preliminary screening of cannabidiol (CBD) revealed that CBD is active against HCV but not against HBV in vitro. CBD inhibited HCV replication by 86.4% at a single concentration of 10 μM with EC50 of 3.163 μM in a dose-response assay. These findings suggest that CBD could be further developed and used therapeutically against HCV. Cannabidiol exhibited in vitro activity against viral hepatitis C.” https://www.ncbi.nlm.nih.gov/pubmed/28250664 “Cannabidiol (CBD) is a nonpsychoactive cannabinoid found in the Cannabis plants and is credited for several pharmacological properties. It is also known to have beneficial effects against inflammation/pain, neurological conditions, cancer, and other ailments. In general, with regard to antiviral activity, medical Cannabis was reported to be used as an accompanying remedy by HIV/AIDS patients to alleviate neuropathic pain, wasting, nausea, and vomiting. Given the increasing use and application of medical Cannabis along with its nonpsychoactive metabolite (CBD), and in line with our continuous effort to evaluate and validate the potential therapeutic properties of CBD, the major aim of this study was as such to evaluate the anti-HBV and anti-HCV activities of CBD in vitro. We report here for the first time in vitro studies to demonstrate the antiviral activity of CBD against HCV. CBD was shown to have activity against HCV in vitro but not against HBV. A review of the literature seems to suggest that CBD may also have activity in vivo based on its interaction with the CB2 receptor and as such using a host mechanism to indirectly slow the pathogenic process of the HBV virus. Based on these findings, CBD as such has potential to be further developed as a treatment for viral hepatitis, especially as a combination therapy with the currently existing therapies.” https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5330095/]]>
Recreational Cannabis — Minimizing the Health Risks from Legalization
“Most adults who occasionally use cannabis find it pleasurable and don’t experience substantial problems.
There is a growing body of research on the medical benefits of consuming cannabis flowers or extracts, and legalization should make it easier to study the therapeutic potential and allow access for patients who could benefit.”
“Early attention to pain and symptoms in those with cancer improves both quality of life and survival. Opioid medications are the mainstay treatment of cancer-related pain.
