March 4, Last Revised: For reprint requests, please see our Content Usage Policy. Marijuana and Cancer Marijuana is the name given to the dried buds and leaves of varieties of the Cannabis sativa plant, which can grow wild in warm and tropical climates throughout the world and be cultivated commercially. Marijuana Different compounds in marijuana have different actions in the human body.
The effects of marijuana also vary depending on how marijuana compounds enter the body: When taken by mouth , such as in baked goods, the THC is absorbed poorly and can take hours to be absorbed. When marijuana is smoked or vaporized inhaled , THC enters the bloodstream and goes to the brain quickly. The second psychoactive compound is produced in small amounts, and so has less effect.
The effects of inhaled marijuana fade faster than marijuana taken by mouth. How can marijuana affect symptoms of cancer? Smoked marijuana has also helped improve food intake in HIV patients in studies. There are no studies in people of the effects of marijuana oil or hemp oil. Possible harms of marijuana Marijuana can also pose some harms to users. Cannabinoid drugs There are 2 chemically pure drugs based on marijuana compounds that have been approved in the US for medical use. It can be taken by mouth to treat nausea and vomiting caused by cancer chemotherapy when other drugs have not worked.
How can cannabinoid drugs affect symptoms of cancer? High blood pressure is linked to higher risks of a number of health conditions, including stroke and heart attack.
Studies indicate that CBD may be a natural and effective treatment for high blood pressure. One recent study treated 10 healthy men with one dose of mg of CBD oil and found it reduced resting blood pressure, compared to a placebo. The same study also gave the men stress tests that normally increase blood pressure. Interestingly, the single dose of CBD led the men to experience a smaller blood pressure increase than normal in response to these tests. Researchers have suggested that the stress- and anxiety-reducing properties of CBD are responsible for its ability to help lower blood pressure.
CBD has been studied for its role in treating a number of health issues other than those outlined above. Though CBD is generally well tolerated and considered safe, it may cause adverse reactions in some people.
CBD is also known to interact with several medications. Before you start using CBD oil, discuss it with your doctor to ensure your safety and avoid potentially harmful interactions.

Today cannabis is undergoing a real renaissance. Apart from cannabis herb medicinal cannabis and botanical extracts, essentially 3 types of cannabinoids exist: Although there are a number of investigational cannabinoids currently in development, the only non-natural, synthetic cannabinoid commercialized today is nabilone with properties that are essentially similar to THC.
It is used for the same indications and marketed in the United States, Canada, and in some European countries. Dosages are about 5 to 10 times lower than with THC. Opposite to purified cannabinoids, extracts contain additional cannabinoids and a range of other bioactive compounds such as flavonoids and terpenoids. Medicinal cannabis, either smoked as dry herb or prepared and taken by vaporizers, has the problem of widely differing compositions and dosages; it is also not allowed in many countries as mentioned before.
Generally, reliability of such claims cannot be controlled. For this reason and due to the availability for therapy, only THC, CBD, and their combination will primarily be considered in this article. However, since its discovery in the s, a number of additional targets and ligands have been identified.
This makes the ECS extremely complex. Because space limitations, reference is also made to recent overviews on specific subjects, rather than to original papers. Palliative care is related to symptom management and supportive care for patients facing life-limiting illness.
It focuses on the amelioration of the quality and duration of remaining life, particularly on physical, emotional, and psychological suffering. Long-term drug safety is also important. Palliative effects of phytocannabinoids, such as on pain, mood, appetite, and radiation- or chemotherapy-induced nausea and vomiting, have been studied in cancer patients since the early s. The striking benefit of these substances is their multitarget action and compatibility with many eventually needed comedications, as well as their impressive safety margin.
Although dosages must be adapted to individual needs, multiple therapeutic effects can be achieved simultaneously with only one product, such as reducing pain, spasticity, depression and anxiety; improving mood and sleep; increasing appetite and weight; etc. Many disease-ameliorating effects of cannabinoids and endocannabinoids are receptor-mediated, but many are not, indicating additional involvement of non-cannabinoid receptor signaling pathways.
A quantitative systematic review 4 that included 30 randomized comparisons of oral THC, nabilone or nabiximols, or the intramuscular levonantradol preparation no longer available with placebo in patients receiving chemotherapy found that, as antiemetics, cannabinoids were more effective than prochlorperazine, metoclopramide, chlorpromazine, thiethylperazine, haloperidol, domperidone, or alizapride.
THC was more effective than odansetron for mildly to moderately severe nausea produced by chemotherapy, but not for severe emetogenic treatments. No single antiemetic is currently available to completely prevent the acute or delayed phases of chemotherapy-induced nausea and vomiting. The most recent guidelines of the National Comprehensive Cancer Network, published in , 6 cautiously mention cannabinoids as a breakthrough treatment for chemotherapy-induced nausea and vomiting not responsive to other antiemetics.
Preclinical research indicates that CBD 2. Low doses suppress toxin-induced vomiting but high doses potentiate. Activation of these autoreceptors reduces the release of 5-HT in terminal forebrain regions. Nausea- and vomiting-reducing effects have also been reported for nabiximols and nabilone.
Loss of appetite and tumor cachexia is a common problem in oncology. A few clinical trials included the change of body weight with THC, but gave mixed results in cancer patients.
An increase in weight was also observed in a crossover, placebo-controlled study with much higher doses 0. In Table 1 , results of studies with THC in cancer patients are summarized.
A case series with 6 patients who received THC showed, however, a loss of effect in 3 of the subjects after several weeks, 19 which may be related to a desensitization of CB1 receptors. It has been hypothesized that weight gain is due to an increase of fat mass as a result of the lipogenic action of THC via CB1 receptors.
In contrast, CBD has no orexigenic effect; high doses 2. Chronic pain is another common symptom and not confined only to tumor patients. A recent review that included THC, nabilone, and nabiximols found moderate-quality evidence to support the use of cannabinoids for the treatment of chronic pain and spasticity.
However, there was no difference in average quality-of-life scores as measured by the EQ-5D health status index between nabiximols and placebo. In a cancer trial, oral THC 20 mg was thought to be comparable to codeine mg, but with more marked psychological effects.
However the dose of CBD—each substance was given as sublingual spray containing 2. Details of some representative studies are given in Table 2. Other notable findings include the reduction in the dose of opioid pain medications with cannabinoids and the blockade of opiate-dependence in rats.
As morphine induces upregulation of CB2 with inflammatory responses in activated microglia and potentially abnormal immune function , cannabinoids are also counteracting this unwanted effect. Mechanisms of CBD seem to be rather complex: Combinations of CBD and morphine produced synergistic effects in reversing acetic acid-stimulated stretching behavior, but subadditive effects in the hot plate thermal nociceptive assay and the acetic acid-decreased operant responding for palatable food assay; thus, the opioid-saving effect of a combination may depend on the pain type.
To note, a dysfunction of TRP channels has been implicated in chronic pain. During the last decades many studies reported that numerous other cancer-related or treatment-related symptoms were also significantly improved by cannabinoids, such as depression, anxiety, fatigue, constipation, sexual function, sleep disorders, and itching.
The only cannabinoid likely having a role in depression is CBD as may be concluded from animal experiments. More generally, cancer patients using cannabis uniformly report better influence from the plant extract than from pure or synthetic products. In a recent review, mixed and somewhat inconsistent results have been reported about effects on sleep with cannabinoids, including nabilone and nabiximols.
Differences between cannabinoids may exist as well. 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.
Integrating cannabis into clinical cancer care
Here are potential uses, from anxiety relief to possible cancer treatment, for CBD oil to fully understand the effects of CBD oil for neurodegenerative diseases. CBD may help alleviate cancer symptoms and cancer treatment side effects. Cannabidiol, or CBD, is a chemical compound in marijuana with a variety CBD may help reduce symptoms related to cancer and side effects. The Cannabis plant yields inactive acidic forms of thc and cbd, namely thc-a and cbd-a. Traditionally, patients with cancer-related symptoms have . Oncologists might be concerned that cannabinoids could reduce the.
