Relying on marijuana alone as treatment while avoiding or delaying conventional medical care for cancer may have serious health consequences. Marijuana can also pose some harms to users. Smoked marijuana delivers THC and other cannabinoids to the body, but it also delivers harmful substances to users and those close by, including many of the same substances found in tobacco smoke. The effects can also differ based on how deeply and for how long the user inhales.
Likewise, the effects of ingesting marijuana orally can vary between people. Also, some chronic users can develop an unhealthy dependence on marijuana. There are 2 chemically pure drugs based on marijuana compounds that have been approved in the US for medical use. Nabiximols is a cannabinoid drug still under study in the US. Based on a number of studies, dronabinol can be helpful for reducing nausea and vomiting linked to chemotherapy.
Dronabinol has also been found to help improve food intake and prevent weight loss in patients with HIV. Research is still being done on this drug. Like many other drugs, the prescription cannabinoids, dronabinol and nabilone, can cause side effects and complications. Some people have trouble with increased heart rate, decreased blood pressure especially when standing up , dizziness or lightheadedness, and fainting. They can also worsen depression, mania, or other mental illness.
Some patients taking nabilone in studies reported hallucinations. The drugs may increase some effects of sedatives, sleeping pills, or alcohol, such as sleepiness and poor coordination. Patients have also reported problems with dry mouth and trouble with recent memory. People who have had emotional illnesses, paranoia, or hallucinations may find their symptoms are worse when taking cannabinoid drugs. Talk to your doctor about what you should expect when taking one of these drugs.
The American Cancer Society supports the need for more scientific research on cannabinoids for cancer patients, and recognizes the need for better and more effective therapies that can overcome the often debilitating side effects of cancer and its treatment. The Society also believes that the classification of marijuana as a Schedule I controlled substance by the US Drug Enforcement Administration imposes numerous conditions on researchers and deters scientific study of cannabinoids.
Federal officials should examine options consistent with federal law for enabling more scientific study on marijuana. The American Cancer Society medical and editorial content team.

Cannabis oil and cancer. Two main cannabinoids have been identified: Cannabis and cancer There has been a lot of interest in cannabinoids. Scientists have found that different cannabinoids can: But they have also found that cannabinoids can: Cannabis oil Cannabis, particularly cannabis oil, is a popular topic.
If you are thinking about using cannabis oil, there are some important things to keep in mind: Buying it online can be risky. There are side effects of using cannabis oil. They may also interact with other drugs. Finding reliable information online If you are looking for information online you want to be sure that it is accurate and up to date.
Here are some things to think about when you are looking at a website: Is the information regularly updated? You should be able to find the date when the information was last reviewed on each page. Is it clear who has written the information? A good website should tell you about the organisation that has made the pages or written the information.
The website should list its sources of information, or tell you who to contact to find out. Is the website sponsored by a company? You might also be interested in. Latest from the Online Community. Many in vitro and in vivo experiments have shown that cannabinoids inhibit proliferation of cancer cells, stimulate autophagy and apoptosis, and have also a potential to inhibit angiogenesis and metastasis.
The review includes also a summary of currently ongoing clinical trials evaluating the safety and efficacy of cannabinoids as anticancer agents. Nowadays, we observe an increasing public and scientific interest in the medical applications of Cannabis plants.
In the USA, marijuana is now allowed for medical applications in 24 states and the District of Columbia. Furthermore, during the last decade, we have collected a great pool of evidence from preclinical and clinical studies that Cannabis and cannabinoids have a therapeutic potential in many medical fields, and can even display some anticancer characteristics. This class of molecules can be divided into three main groups: Phytocannabinoids are secondary metabolites of Cannabis plants. Action of THC in human organism relies on mimicking endogenous agonists of CB receptors—endocannabinoids 3.
Another phytocannabinoid which gains medical attention is cannabidiol CBD. It has low affinity for cannabinoid receptors and acts independently of them. They have been proposed to be classified as CB receptors, but their exact role in endocannabinoid signaling is still under discussion 3.
Endocannabinoids are part of the endocannabinoid system, which is composed of cannabinoid receptors, their endogenous ligands, and the enzymes involved in their metabolism. To date, two cannabinoid receptors CB1 and CB2 have been identified in mammalian tissues 5 , 6. Its high expression has been observed in these areas of central nervous system, that are engaged in the modulation of motor behavior, memory, learning, emotions, perception, and endocrine functions 3 , 8. CB2 receptors have been found in immune cells, but their presence was revealed also in nervous system 10 , In addition to its neuromodulatory function, endocannabinoid system has been shown to play other important functions such as control of the energy metabolism, immunity, cardiovascular tone, and reproduction 12 , According to the contribution of the endocannabinoid system in a regulation of such variety of processes, its pharmacological modulation becomes promising therapeutic strategy.
To date, cannabinoids have been exploited in the palliative medicine. Nabilone THC synthetic analogue is allowed for the treatment of nausea and vomiting induced by chemotherapy, and sleep disorders. 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
