For the cancer patient, cannabis has a number of potential benefits, especially in the management of symptoms. Cannabis is useful in combatting anorexia, chemotherapy-induced nausea and vomiting, pain, insomnia, and depression. Cannabis might be less potent than other available antiemetics, but for some patients, it is the only agent that works, and it is the only antiemetic that also increases appetite. Inhaled cannabis is more effective than placebo in ameliorating peripheral neuropathy in a number of conditions, and it could prove useful in chemotherapy-induced neuropathy.
A pharmacokinetic interaction study of vaporized cannabis in patients with chronic pain on stable doses of sustained-release opioids demonstrated no clinically significant change in plasma opiates, while suggesting the possibility of synergistic analgesia. Aside from symptom management, an increasing body of in vitro and animal-model studies supports a possible direct anticancer effect of cannabinoids by way of a number of different mechanisms involving apoptosis, angiogenesis, and inhibition of metastasis.
Despite an absence of clinical trials, abundant anecdotal reports that describe patients having remarkable responses to cannabis as an anticancer agent, especially when taken as a high-potency orally ingested concentrate, are circulating. Human studies should be conducted to address critical questions related to the foregoing effects. Magnetic resonance imaging revealed that the princess had a primary tumour in the right breast, with axial adenopathy and metastatic disease.
It is hypothesized that the cannabis was used to manage her pain and perhaps other symptoms, or even possibly as a treatment for her malignant disease. Widely used as medicine during the ensuing millennia, cannabis disappeared from the pharmaceutical armamentarium in the s as its prohibition took hold.
Today, we are in the midst of what appears to be something of a medicinal cannabis renaissance, with patients across the globe gaining increased access to this potent botanical medicine. Regrettably, most oncologists trained during the era of cannabis prohibition and have no knowledge of how to use the plant as medicine.
In these days of targeted therapies and nanotechnology, the modern oncologist might feel somewhat ill at ease recommending a herbal intervention, notwithstanding the number of potent cytotoxic chemotherapeutic agents derived from plants. An even more vexing concern to the oncologist is the lack of data on which to base treatment recommendations. Given the nature of the drugs that they prescribe, oncologists are used to seeing strong evidence of a favourable risk—benefit ratio before recommending a therapeutic intervention.
Usually, oncology drugs have proceeded through preclinical studies, followed by the traditional phase i , ii , and iii analyses, before we feel comfortable adding them to our toolbox. Such data about the clinical effectiveness of medicinal cannabis are all but lacking. In the United States, cannabis is classified as a Schedule I agent with a high potential for abuse and no accepted medical use.
The study of cannabis requires a special Schedule I license from the U. In addition, the only legal source of cannabis for clinical trials is the National Institute on Drug Abuse, which has a congressional mandate to study substances of abuse only as substances of abuse.
Although investigators can obtain National Institute on Drug Abuse cannabis to conduct effectiveness clinical trials, funding must come from another source. Hence, carefully controlled clinical trials of cannabis as a therapeutic agent—the sorts of trials that would satisfy a data-driven oncologist—are quite rare.
Hence, oncologists probably have the longest record of using a cannabis-based medicine. In , the dronabinol indication was expanded to include treatment of the anorexia associated with aids wasting syndrome. In , nabilone Cesamet: The foregoing drugs are thc alone and do not include any of the other potentially therapeutic cannabinoids, terpenoids, or flavonoids that are present in the whole plant 3. Cannabidiol cbd , in particular, is another of the phytocannabinoids that has been generating significant interest for its potential therapeutic effects 4.
GW Pharmaceuticals, Salisbury, U. Originally approved in Europe for the treatment of central pain associated with multiple sclerosis, this sublingual preparation has also been studied in a number of cancer-related conditions 5 — 8. Because most of the information derived from clinical trials on cannabinoids in cancer is derived from studies of those licensed pharmaceuticals, the present review discusses findings from studies of those agents as well as from studies of cannabis itself.
To date, two types of cannabinoid receptors seven-transmembrane domain G protein—coupled receptors have been identified in humans and other animal species 9. The cb1 receptor, initially identified in the brain, is found in high concentrations in areas involved in the processing of noxious stimuli. The cb2 receptor is predominantly located in cells of the immune system and likely has a role in the control of inflammation and cell proliferation. The cb receptors are not present to react with the phytocannabinoids from cannabis alone.
It has been suggested that the entire function of the system of cannabinoid receptors and endocannabinoids might be to assist in modulation of the response to pain. With that in mind, it is not surprising that an increasing body of knowledge is being developed about the effects on pain of cannabinoid medicines.
A recently published systematic review 10 considered 28 studies involving a total of participants and preparations including inhaled cannabis, dronabinol, nabilone, and nabiximols, among others. Twelve of the studies investigated neuropathic pain, and three looked at patients with cancer pain. The studies generally showed improvement in pain measures, with an overall odds ratio of 1.
An earlier systematic review of eighteen randomized controlled trials of cannabinoids in participants with chronic non-cancer pain found that fifteen of the studies reported a significant analgesic effect for the cannabinoids compared with placebo, and a number of the studies also noted improvements in sleep Another review that included six of those eighteen studies in patients with cancer-related pain also favoured cannabinoids Neuropathic pain is certainly problematic in cancer patients A systematic review of six randomized, double-blind, placebo-controlled trials of cannabinoids five specifically addressing neuropathic pain found evidence for the use of low-dose medical cannabis in refractory neuropathic pain in conjunction with traditional analgesics Another analysis reviewed five trials of inhaled cannabis in patients with hiv -related peripheral neuropathy and again found a positive effect for cannabis compared with placebo A recent small study 16 showed a dose—response effect for vaporized cannabis in the relief of pain from diabetic peripheral neuropathy, a huge clinical problem estimated to affect million people worldwide.
With all of those impressive data suggesting that cannabinoids could be effective in peripheral neuropathy, where are the studies in patients with chemotherapy-induced peripheral neuropathy? Preclinical studies in rodent models have suggested that cannabinoids might actually be able to prevent peripheral neuropathy.
Activation of the cb1 and cb2 receptors suppresses the development of vincristine-induced peripheral neuropathy in rats In mice receiving daily cisplatin, administration of anandamide an endocannabinoid together with an inhibitor of the fatty-acid amide hydrolase that metabolizes anandamide attenuated chemotherapy-induced peripheral neuropathy Cannabidiol pretreatment stops paclitaxel-induced neuropathy in mice To date, the only human study of a cannabis-based medicine in chemotherapy-induced peripheral neuropathy is a crossover placebo-controlled trial of nabiximols Overall, reported pain scores were not different with nabiximols and with placebo.
However, on a 0—10 scale, 5 responders reported a greater than 2-point decline in neuropathic pain. That observation suggests that 5 patients have to be treated with the sublingual preparation for 1 to experience clinical benefit an acceptable number-needed-to-treat for a neuropathic condition , suggesting that further investigation of cannabis medicines in chemotherapy-induced peripheral neuropathy is warranted.
Even more exciting would be a study demonstrating the potential for cannabis to actually lower the risk for neuropathy or to prevent it from developing in the first place, as the animal models suggest. In animal models, cannabinoids and opioids have been demonstrated to have synergistic analgesic effects Analgesic effects of cannabinoids are not blocked by opioid antagonists, suggesting that the two types of agents work through different receptors and pathways. An early study found that thc was ineffective as an analgesic on its own, but that it slightly increased the effect of morphine on 2 of 3 measures A randomized controlled trial of nabiximols in cancer patients with poorly controlled pain despite a stable opioid regimen found that the sublingual preparation 4, 10, or 16 sprays daily for 5 weeks reduced both pain and sleep disruption A pharmacokinetic interaction study of vaporized cannabis in 21 patients with chronic—mostly non-cancer—pain taking sustained-release morphine or sustained-release oxycodone showed no significant effect on plasma levels of the opiates, but a suggestion of enhanced analgesia However, that small study was not powered for a pain endpoint, suggesting that a larger follow-on trial is warranted Clinically, I have observed that many cancer patients benefit from adding cannabis to their pain regimen.
Although the effect on chemotherapy-induced peripheral neuropathy has not been glaringly obvious, other sorts of cancer-related pain appear to respond. Patients who have been put on high doses of opiates at the end of life by their well-meaning oncologist or palliative care team frequently feel totally unable to communicate with their loved ones in their precious remaining time because of altered cognition.
Many have successfully weaned themselves down or off their opiate dose by adding cannabis to their regimen. Although it would seem that thc -dominant strains of cannabis would be most likely to have analgesic effects, patients often report significant pain reduction from strains that are predominantly cbd -rich.
Although cbd does not actually bind to the cb1 receptor, it does block the fatty-acid binding protein that transports the endocannabinoid intracellularly to be hydrolyzed by the fatty-acid amide hydrolase, hence allowing the endogenous cannabinoid complexed with the receptors to persist As an oncologist practicing medicine in San Francisco since the early s, I have often said that I need a clinical trial to demonstrate that cannabis is an effective antiemetic about as much as I need a placebo-controlled trial to demonstrate that penicillin is an antibiotic!
It would appear that, if the single most active constituent of the plant is licensed and approved for treatment of chemotherapy-induced nausea, that the parent botanical should also work. Being aware that the plural of anecdote is not evidence, I would like to share an e-mail message from a year-old gentleman with metastatic colon cancer requesting a renewal of his medical cannabis authorization:.
A number of small studies of smoked marijuana found that it can be helpful in treating nausea and vomiting from cancer chemotherapy. A few studies have found that inhaled smoked or vaporized marijuana can be helpful treatment of neuropathic pain pain caused by damaged nerves.
Studies have long shown that people who took marijuana extracts in clinical trials tended to need less pain medicine. Some animal studies also suggest certain cannabinoids may slow growth and reduce spread of some forms of cancer. There have been some early clinical trials of cannabinoids in treating cancer in humans and more studies are planned. While the studies so far have shown that cannabinoids can be safe in treating cancer, they do not show that they help control or cure the disease.
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.
