Cannabinoids: Medical implications

Herbal cannabis has been used for thousands of years for medical purposes. With elucidation of the chemical structures of tetrahydrocannabinol (THC) and cannabidiol (CBD) and with discovery of the human endocannabinoid system, the medical usefulness of cannabinoids has been more intensively explored. While more randomized clinical trials are needed for some medical conditions, other medical disorders, like chronic cancer and neuropathic pain and certain symptoms of multiple sclerosis, have substantial evidence supporting cannabinoid efficacy.

Plant-Based Cannabinoids for the Treatment of Chronic Neuropathic Pain

Chronic neuropathic pain is a prevalent condition that places a heavy burden on individuals and the healthcare system. Current medications have limitations and new approaches are needed, particularly given the current opioid crisis. There is some clinical evidence that the plant Cannabis sativa produces relief from neuropathic pain. This animal data suggests that cannabidiol and low dose nabiximols warrant consideration for clinical studies, at least as adjuvants to current drugs. Preclinical research is also required to identify other phytocannabinoids that have therapeutic potential.

The Consumption of Cannabis by Fibromyalgia Patients in Israel

To report on the habits of cannabis consumption among fibromyalgia patients in Israel. An Internet-based questionnaire was posted to three large fibromyalgia Facebook groups in our country. Cannabis consumption among fibromyalgia patients in our country is very common and is mostly not licensed. Nearly all CC reported favorable effects on pain and sleep, and few reported adverse effects or feeling of dependence on cannabis

Systematic Review of the Costs and Benefits of Prescribed Cannabis-Based Medicines for the Management of Chronic Illness: Lessons from Multiple Sclerosis

Cannabis-based medicines (CBMs) may offer relief from symptoms of disease; however, their additional cost needs to be considered alongside their effectiveness. We sought to review the economic costs and benefits of prescribed CBMs in any chronic illness, and the frameworks used for their economic evaluation. Prescribed CBMs are a potentially cost-effective add-on treatment for MS spasticity; however, this evidence is uncertain. Further investment in randomised trials with in-built economic evaluations is warranted for a wider range of clinical indications.

Current status of cannabis treatment of multiple sclerosis with an illustrative case presentation of a patient with MS, complex vocal tics, paroxysmal dystonia, and marijuana dependence treated with dronabinol

Pain, spasticity, tremor, spasms, poor sleep quality, and bladder and bowel dysfunction, among other symptoms, contribute significantly to the disability and impaired quality of life of many patients with multiple sclerosis (MS). Motor symptoms referable to the basal ganglia, especially paroxysmal dystonia, occur rarely and contribute to the experience of distress. An illustrative case is presented of a 52-year-old woman with MS, paroxysmal dystonia, complex vocal tics, and marijuana dependence.

Medical marijuana: medical necessity versus political agenda

Marijuana is classified by the Drug Enforcement Agency (DEA) as an illegal Schedule I drug which has no accepted medical use. However, recent studies have shown that medical marijuana is effective in controlling chronic non-cancer pain, alleviating nausea and vomiting associated with chemotherapy, treating wasting syndrome associated with AIDS, and controlling muscle spasms due to multiple sclerosis.
Patients have a right to all beneficial treatments and to deny them this right violates their basic human rights.

The Endogenous Cannabinoid System: A Budding Source of Targets for Treating Inflammatory and Neuropathic Pain

A great need exists for the development of new medications to treat pain resulting from various disease states and types of injury. Given that the endogenous cannabinoid (that is, endocannabinoid) system modulates neuronal and immune cell function, both of which play key roles in pain, therapeutics targeting this system hold promise as novel analgesics. Here we examine the preclinical and clinical evidence of various endocannabinoid system targets as potential therapeutic strategies for inflammatory and neuropathic pain conditions.

Effect of adding medical cannabis to analgesic treatment in patients with low back pain related to fibromyalgia: an observational cross-over single centre study

Low back pain (LBP) occurs in many patients with fibromyalgia (FM). The current study aimed to assess the possible pain and function amelioration associated with medical cannabis therapy (MCT) in this setting. This observational cross-over study demonstrates an advantage of MCT in FM patients with LBP as compared with SAT. Further randomised clinical trial studies should assess whether these results can be generalised to the FM population at large.

The level of evidence of medical marijuana use for treating disabilities: a scoping review

Twenty-nine states have bypassed federal regulations by legalizing marijuana (MJ) either medicinally, recreationally or both. The FDA states that there is no empirical evidence that MJ is effective to treat these disorders. With over a billion individuals living with a disability across the globe, it is crucial to fully research the efficaciousness and safety of medical MJ to treat this population. The purpose to present the results of a scoping review of studies focused on the levels of evidence currently available on medical MJ’s efficacy in treatment across a large range of disabilities.
