Dronabinol synthetic THC is approved also for nausea and vomiting due to chemotherapy and for the treatment of weight loss associated with AIDS. Medical Cannabis in the form of marijuana dried flowers and leafs is illegal in the USA at the federal level according to the Controlled Substances Act as a Schedule I substance, but some states have legalized it for medical purposes Besides palliative properties of cannabinoids, it has been shown in wide range of in vitro and animal models, that they also exhibit anticancer effects 7 , 15 , 16 , Despite numerous studies conducted during the last decade, there are still inconsistent data regarding the exact role of cannabinoid system in cancer development.
The upregulated expression of CB receptors and the elevated levels of endocannabinoids have been observed in a variety of cancer cells skin, prostate, and colon cancer, hepatocellular carcinoma, endometrial sarcoma, glioblastoma multiforme, meningioma and pituitary adenoma, Hodgkin lymphoma, chemically induced hepatocarcinoma, mantel cell lymphoma , but it is not always correlated with the expression level of these receptors in tissue of origin 7 , 11 , 18 , Furthermore, concentration of endocannabinoids, expression level of their receptors, and the enzymes involved in their metabolism frequently are associated with an aggressiveness of cancer.
This implies that an overactivation of endocannabinoid system might be protumorigenic and plays an essential role in the development of cancer 20 , On the other hand, there are reports indicating that an activation of the cannabinoid receptors can impair cancer development and hence endocannabinoid signaling can be antitumorigenic.
Furthermore, it has been shown that silenced expression of CB1 receptor leads to an acceleration of intestinal adenoma growth, whereas activation of this receptor attenuates its growth in murine model The elevated level of endocannabinoids has been shown to reduce the development of precancerous lesions in mouse colon On the other hand, there are reports that have indicated that under certain circumstances, cannabinoids can be protumorigenic 31 , 32 , It has been shown that CB1 and CB2 receptor agonists stimulate apoptotic cell death in glioma cells by induction of de novo synthesis of ceramide, sphingolipid with proapoptotic activity 34 , If this response fails, ER stress can lead to activation of intrinsic apoptosis pathway The known mechanisms responsible for the induction of apoptosis by cannabinoids.
It has been demonstrated that process of autophagy is upstream of apoptosis in mechanism of cell death induced by cannabinoids.
An inhibition of autophagy prevents apoptosis induced by cannabinoids, while an inhibition of apoptosis prevents only cell death but not the autophagy 39 , 41 , 42 , It has been shown that cannabinoids induce process of autophagy in cancer cell lines such as glioma, melanoma, hepatic, and pancreatic cancer 39 , 41 , 42 , Moreover, some additional mechanisms have been demonstrated to contribute to the process of an induction of cell death by cannabinoids in certain cell lines.
Similar results have been obtained in prostate carcinoma cells Table S1 Cannabinoids devoid of psychoactive properties also exhibit anticancer potential. They do not affect CB receptors directly and their exact mechanism of action is still not fully elucidated.
Another interesting explanation is that CBD can prevent the degradation of anandamide AEA and subsequently leads to increased endocannabinoid concentration by acting as an inhibitor of fatty acid amide hydrolase FAAH 52 , This notion raises the possibility that the observed actions of CBD can be, in fact, partially the result of an elevated level of AEA.
These observations are in line with the described earlier relations between endocannabinoids and cancer development. Most of the research implicates that the action of CBD and other cannabinoids devoid of psychoactive properties is not linked to a direct activation of the CB receptors. However, there are reports suggesting that CBD can induce apoptosis in cancer cells partially via direct or indirect activation of CB2 receptor Recent studies have shown that CBD reduces cancer cell viability in many cancer types such as neuroblastoma, glioblastoma, melanoma, leukemia, colorectal, breast, lung, or prostate cancer Table S1 41 , 50 , 51 , 54 , 56 , 57 , 58 , The mechanism of the immunomodulatory effects of cannabinoids is still not fully elucidated.
Research has been focused mainly on the CB2 receptor, mostly due to its expression primarily in cells of the immune system. CB1 receptors have been noticed in the T lymphocytes and it is proposed that their activation may be connected with the cytokine biasing induced by cannabinoids The highest level of CB2 expression has been observed in B cells, followed by NK cells, monocytes, polymorphonuclear neutrophils, and T cells It has been shown that the expression level of CB2 correlates with the cell activation state and with the presence of immune modulators The immune system is postulated to be involved in the control of growth and development of many types of cancer.
One of the key regulators of the antitumor immune response is cytokines profile. It is postulated that a Th1 response is crucial for an effective immune response against many tumors Phytocannabinoids with high affinity for CB2 receptors, such as THC, exhibit modulatory effects on both cellular and humoral immunity.
Nonpsychotropic cannabinoids with low affinity for CB receptors have also been proven to exhibit immunomodulatory action. Most of the studies indicate that cannabinoids exhibit immunosuppressive action The most extensively examined immunomodulatory effects of cannabinoids in context of cancer are regarding the changes in the activity of T cells.
It has also been proposed that cannabinoids can affect T cells by the induction of apoptosis 73 , Another possibility is that cannabinoids effects on immune cells are at least partially induced indirectly via other suppressive mechanisms such as release of cortisone The effects on the Th17 cells subsets have not been fully described to date.
Interestingly, CB receptors seem to take part in the modulation of those phenomena Indeed, there are reports indicating the suppression of anticancer immune response by THC. It has been demonstrated that THC suppresses host immune reactivity against cancer in murine lung cancer model Lewis lung carcinoma, 3LL and line 1 alveolar cell carcinoma L1C2 , leading to the increase in the tumor growth CB2 receptors antagonists also blocked the effects of THC administration.
Similar results were obtained in the study of mouse mammary carcinoma. It has been demonstrated that THC exposure leads to the significant increase in the 4T1 carcinoma growth and metastasis due to the inhibition of the specific antitumor immune response Observed effects were mediated by CB2 receptors It is possible that tumors originating from tissues of low CB receptors expression would be significantly less sensitive to cannabinoids anticancer action and, eventually, due to THC immunosuppressive properties, such tumors may find a favorable environment for growth and development.
It is also possible that anticancer properties of cannabinoids may be compensated by their immunosuppressive action, finally leading to promotion of the tumor growth. Chronic inflammation has been associated with the development of neoplasia; therefore, reducing inflammation may, to some extent, contribute to the prevention of carcinogenesis. Viability of noncancerous cells seems to remain unchanged or sometimes even elevated by cannabinoids 34 , 35 , 36 , 39 , On the other hand, cannabinoids can trigger apoptotic cell death in some types of nontransformed cells, especially those of high proliferative properties such as endothelial cells The cellular response to cannabinoids relies on different mechanisms in cancerous and noncancerous cells.
It has been demonstrated in vitro that cannabinoids can exhibit a stimulatory activity in nanomolar concentration and an inhibitory activity in micromolar concentration biphasic response , which significantly exceeds concentrations usually detected in blood of marijuana smokers Concentration of THC used in described experiment corresponded to its serum concentration obtained by smoking or oral administration of THC Besides the above described proapoptotic effect in cancer cells, cannabinoids exhibit some other important and potentially valuable properties.
It has been demonstrated that they can inhibit angiogenesis by blocking an activation of the vascular endothelial growth factor VEGF pathway. Cannabinoids have also been shown to reduce spontaneous and induced metastases in animal models and to inhibit an invasiveness of cancer cells in vitro breast, lung, cervical cancer, and glioma 86 , 87 , 88 , 89 , It can be sold in the UK as long as it is sold as a food supplement and the sellers are not making any claim about its medicinal properties.

Cannabis has been shown to kill cancer cells in the laboratory and there are currently many research projects worldwide exploring whether its properties could be harnessed to help stem the growth of malignant tumours.
Several of these studies are summarised in this Nature Reviews Cancer report. However, while many of these studies show exciting early promise, killing cancer cells in a laboratory is far simpler than killing cancer cells in the human body. Until a cancer treatment has gone through the full stages of testing in animals and people, we cannot be certain that it works. Decades of cancer research has demonstrated that cancer is an incredibly complex and varied disease that varies from person to person and tumour to tumour.
