Alleviate Symptoms CBD Cancer-Related
THC seems to decrease the time to sleep latency and to improve sleep quality over a wide dose range of 2. In rats, very low doses of about 0. RBD is a sleep disorder that causes people to act out their dreams. Common symptoms include talking, shouting, and complex movements associated with nightmares.
Three of the patients received 75 mg of CBD per day and 1 received mg per day. All 4 patients experienced a significant reduction in symptoms following treatment. Probably the most exciting property of cannabis, scientific evidence for anticancer effects, goes back to at the Medical College of Virginia at the behest of the US government, about 2 decades before the endocannabinoid system and mechanism of its actions had been detected.
Funded by the National Institutes of Health to find evidence that marijuana damages the immune system, the study found instead that THC slowed the growth of 3 kinds of cancer in mice—lung and breast cancer, and a virus-induced leukemia. Astrocytomas and in particular glioblastomas are the most frequent brain tumors among approximately different types.
Malignant glioma remains one of the most aggressive forms of brain cancer, with a median survival after resection, radiotherapy and chemotherapy of 12 to 15 months.
In children, brain tumors constitute the second-most-common malignancy. When cells become malignant, they develop more cannabinoid receptors and become more susceptible to endocannabinoids, thus enabling an efficient intervention.
In most brain tumors the endocannabinoid system is upregulated and seems to be under epigenetic control. Interestingly, some benign pediatric astrocytic tumors, such as subependymal giant cell astrocytoma, which may only occasionally cause mortality owing to progressive growth, also display high CB2 immunoreactivity. Cannabinoids decrease tumor progression by at least 2 mechanisms: Initial studies showed that THC and other cannabinoids induce the apoptotic death of glioma cells by CB1- and CB2-dependent stimulation of the de novo synthesis of the proapoptotic sphingolipid ceramide.
Therefore, additional, nonreceptor mechanisms such as induction of reactive oxygen species seem to be plausible. The first and only published clinical study aimed at assessing antitumoral action of THC in humans was a pilot phase 1 trial in 9 patients with recurrent glioblastoma multiforme.
All of them had previously failed standard therapy surgery and radiotherapy and had clear evidence of tumor progression at the time they received THC. The median duration of an administration cycle was 10 days; 5 patients received more than 1 cycle. In 3 of these 5 patients, a temporary reduction of tumor proliferation was observed. THC administration was safe without overt psychoactive effects. In 2 patients who received THC for 30 and 26 days, respectively, and in whom CB receptor expression had been determined after THC treatment, a slight decrease in CB1 receptor expression but no change in CB2 receptor expression was observed, which might reflect a predominant binding of THC to the former protein or its higher susceptibility to desensitization.
Maximal doses of THC and CBD in these 2 trials are about 5- to times lower than doses that were effective in animal studies see below. In contrast to THC, CBD does not interact directly with CB1 and CB2 receptors but produces nonetheless a remarkable antitumor effect in glioma as well in a number of other animal models of cancer, including reduction of invasiveness and metastasis.
The mechanisms by which CBD kills glioma cells, independently of cannabinoid receptor stimulation, both in vivo and in vitro, has not as yet been completely clarified.
It seems to rely—at least in part—on its ability to inhibit the transcription of tumor-related genes eg, midkine, MDK and enhance the production of reactive oxygen species in cancer cells. CBD also decreases the activity and content of 5-lipoxygenase. It is therefore of particular interest that CBD significantly downregulates Id-1 gene expression and associated glioma-cell invasiveness and self-renewal at concentrations that can be achieved in vivo.
A number of reports on treatment of various brain tumors with cannabis exist in the internet but are unfortunately restricted to inconclusive or poorly documented anecdotal testimonials on various cannabis extracts eg, hemp oil used by patients or their relatives 63 ; this includes also a report on spontaneous regression of pilocytic astrocytoma after incomplete resection in 2 children. A recent review article emphasized that all 16 in vivo studies that evaluated cannabinoid action on glioma so far showed statistically significant reductions of tumor volumes when comparing to controls.
Duration of treatment was between 7 and 28 days. Results are summarized in Table 3 and also include publications since the data lock date of AM review, December Combinations with temozolomide, X-rays, or cannabinoids enhanced the activity further. One study demonstrated that higher doses of THC were more effective, thus confirming a dose-dependency observed already in vitro; differences in sensitivity of glioma cells to cannabinoids exist.
In short, a number of experiments, in vitro and in vivo, have demonstrated that cannabinoids act synergistically, which is of great importance for the development of future anticancer therapies. The treatment of glioblastoma cells with both compounds, THC and CBD, led to significant modulations of the cell cycle and induction of reactive oxygen species and apoptosis as well as specific modulations of extracellular signal-regulated kinase and caspase activities.
These specific changes were not observed with either compound individually, indicating that the signal transduction pathways affected by the combination treatment were unique. A steadily increasing number of publications demonstrate the high potential of cannabinoids in palliative care. They can be combined with other therapies and seem to be devoid of any significant toxicity. Effects differ, however, between cannabinoids and change also with increasing doses whereby many aspects remain unsolved.
However, CB1 stimulation is necessary for improving mood and appetite and many other effects. At present, it is hard to imagine a better approach than adjusting THC doses individually to balance wanted versus unwanted effects. Generally, higher doses are needed to achieve analgesic and antiemetic effects. Such high doses preclude an oral use of THC as single substance in humans due to side effects.
Many questions are also unsolved when it comes to chronic treatment with cannabinoids, a particularly important point in palliative care. Full recovery of CB1 receptors after stopping THC for example may take up to several weeks, with regional differences. Is a daily treatment, as commonly practiced, necessary or is a pulse-dosing concept with intermittent dosages given as short cycles a better alternative? How long last effects? CBD and possibly other non-psychotropic cannabinoids, may be a promising alternative for many indications, likely to include nausea, vomiting and improvement of sleep, although more studies in humans are necessary.
Combinations were synergistic under many circumstances such as in pain and antitumor studies. Cannabinoids differ in their antitumor activities and probably in their mechanisms and targets, which is a rationale for combinations.
However, for many pharmacological effects except against tumors roughly times higher daily doses are needed for CBD compared to THC. This leaves some doubts as to whether a 1: A further, unsolved question is whether the common intervention strategy of 1 to 3 applications of cannabinoids per day can be optimized. More recent findings demonstrate that the activity of the ECS is profoundly modulated by circadian rhythmicity.
As an example, CB1 receptor protein is at its highest concentration when AEA levels are lowest and vice versa, whereas the expression of CB2 did not show striking diurnal differences, at least in the rat cerebral cortex. In contrast, levels of 2-AG, a full agonist to CB1 receptors and about times more abundant in brain than AEA, follow an opposite course. Concentrations are lowest around In rats, an AEA injection before experimentally induced traumatic brain injury significantly increased survival when traumatic brain injury was induced at This suggests that the time of administration of cannabinoids could also modulate effects.
Last but not least, nutrition also plays an important role in palliative care. Some pathways of their degradation produce, among others, proinflammatory compounds. A recent study found that 2-AG plasma levels were significantly reduced by a diet high in omega-3 and low in omega-6 fatty acids H3-L6 intervention , which in turn significantly decreased severity of headaches. In summary, the endocannabinoid system is likely playing a crucial role in palliative care.
The future will show whether an optimized treatment strategy with cannabinoids can also prolong life of brain tumor patients by their virtue to combat cancer cells. Oxford University Press is a department of the University of Oxford.

CBD oil might also help alleviate cancer-related symptoms such as chemotherapy-induced nausea. Because of this, some chemotherapy patients seek alternatives, including CBD oil. Another CBD oil benefit to consider? It might alleviate muscle spasticity caused by multiple sclerosis.
Another benefit of CBD oil? Anticipatory nausea is nausea that occurs in anticipation of chemotherapy treatment, and is a condition that is very difficult to treat in patients undergoing longer-term chemotherapy. So the ability of CBD to help reduce this nausea could be a big benefit to cancer patients. CBD also has great promise as an anti-tumor compound which can help to stop of the spread of cancer metastasis.
There is quite a bit of evidence that CBD inhibits cancer cell migration, adhesion, and invasion, making it a potent inhibitor of both cancer growth and spread. You can read more about the anti-cancer effects of CBD by clicking the blue button above.
