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. Our team is made up of doctors and master's-prepared nurses with deep knowledge of cancer care as well as journalists, editors, and translators with extensive experience in medical writing.

The end point of primary interest was antiemetic efficacy. Different end points for antiemetic efficacy were reported. Because of this inconsistency in definitions we extracted only dichotomous data that came closest to complete control that is, absence of nausea or vomiting in the first 24 hours of chemotherapy.
These data were not further analysed. The end point of secondary interest was the number of patients who, after completion of the trial, expressed preference for cannabis or control for future chemotherapy cycles.
Data on adverse effects were extracted when reported in dichotomous form. We looked for a dose-response relation in data from clinically homogeneous subgroups. Such subgroups had to report comparisons of different doses of one cannabinoid for instance, nabilone with one comparator for instance, placebo , have a similar underlying emetogenic risk for instance, highly emetogenic chemotherapy with cisplatin , and have a well defined end point for instance, complete control of vomiting.
We screened reports; 51 were potentially relevant randomised controlled trials. Twenty one were subsequently excluded. Seven were not primarily studies of cannabinoids or had no relevant information. Five randomised trials four reports were excluded because they reported emesis data per chemotherapy cycle only and no other relevant data could be extracted, 24 the data could not be analysed, 25 the study design was unclear, 26 or the study used only physiological measurements.
Thus, efficacy data from patients could be analysed. The average trial size was 46 patients range 8 to The median quality score was 4 range 1 to 4 ; 17 scored 4, eight 3, two 2, and three 1. Since the results from crossover trials were usually reported as if they had come from a parallel group trial we used the data accordingly. The median number of chemotherapy cycles was two range one to six. Two trials were in children, 34 , 39 and one in both children and adults. Various tumours were treated.
Five trials reported on the number of patients with a history of cannabis use. Characteristics of studies included in systematic review of cannabinoids for chemotherapy induced nausea and vomiting. Three different cannabinoids were tested. Oral nabilone was tested in 16 trials, oral dronabinol in 13, and intramuscular levonantradol in one. Nabilone doses ranged from 1 mg per 24 hours in children 34 to 8 mg per 24 hours in adults 40 ; the commonest dose was 4 mg per 24 hours.
Dronabinol regimens were most often given according to body surface area in m 2. Commonest controls were prochlorperazine 12 trials , and placebo 10 trials.
Other comparators were metoclopramide four , chlorpromazine two , thiethylperazine one , haloperidol one , domperidone two , and alizapride one. In 14 trials, the observation period was clearly defined as 24 hours. In the other trials, chemotherapy cycles may have lasted longer, but it was unclear how long observations continued for antiemetic efficacy. We had to assume for all these trials that they reported antiemetic efficacy per patient within 24 hours—that is, acute antiemetic efficacy.
In one trial, additional efficacy data were clearly defined for days 2 to 4—that is, delayed antiemetic efficacy. This was not considered for combined analyses. Twelve trials reported antiemetic efficacy with various scoring systems, but we could not extract dichotomous data on the number of patients who were completely free of nausea or vomiting.
Incidences of nausea and vomiting with cannabinoids and control treatments. Each symbol represents one trial. Data are from 10 trials that reported separate dichotomous data on nausea or vomiting. Two trials had two comparators active and placebo and nine trials had data on both nausea and vomiting. Symbol sizes are proportional to trial sizes.
The solid line represents equality. Six to eight patients needed to be treated with cannabinoids for one to benefit who would have vomited or had nausea had they all received a conventional antiemetic.
Control of nausea and vomiting and patients' preference for treatment in trials of cannabinoid against active antiemetic or control treatment. One trial reported very low event rates in the control groups: It became clear that cannabinoids were antiemetic only when the components of the chemotherapy regimen and the event rates in control patients suggested a medium emetogenic setting. We therefore tried to test for dose responsiveness after excluding trials that reported extreme event rates in control groups.
For the same reason, no conclusion could be drawn on the relative efficacy of nabilone, dronabinol, or levonantradol. At the end of 18 crossover trials, patients were asked which treatment they preferred for further chemotherapy cycles. A subgroup analysis, taking into account history of cannabis use, was not possible since this was inconsistently reported.
Percentages of patients preferring cannabinoids or control for future chemotherapy. This difference that was not significant relative risk 0. Hallucinations and paranoia occurred exclusively with cannabinoids. Rates of side effects among patients receiving cannabinoid antiemetic treatment compared with placebo or active control.
The evidence we have from randomised trials shows cannabinoids to be slightly better than conventional antiemetics for treating chemotherapy induced emesis, and patients prefer them. They are also more toxic. Two extreme positions could be taken, perhaps using the following arguments. The optimistic position favours cannabinoids. Overwhelmingly, patients preferred cannabinoids for future chemotherapy, even though cannabinoids were only slightly more effective than other antiemetics and only for moderately emetogenic chemotherapy.
Patients' subjective view on preference is more important than the scientifically evaluated efficacy of that intervention.
Although side effects occur more often with cannabinoids, these may be concentrated in a fairly small number of patients so that most patients find cannabinoids effective without undue adverse effects.
There are even some potentially beneficial side effects. Some patients may perceive a degree of sedation or somnolence as useful during chemotherapy. Thus, further clinical trials with cannabinoids in chemotherapy are justified. The pessimistic position favours conventional antiemetics, as cannabinoids are not much better, and their toxicity is unacceptably high dizziness, dysphoria, hallucinations, paranoia.
The toxic effects may lead to study withdrawal. There were no comparisons of cannabinoids with a serotonin 5-HT 3 receptor antagonist, the best comparator for prevention of acute emesis in highly emetogenic chemotherapy. It is, however, unlikely that cannabinoids would be more effective and less toxic than a 5-HT 3 receptor antagonist.
The correct position is probably somewhere in the middle. Undoubtedly, most patients preferred cannabinoids for future chemotherapy cycles. One in two compared with placebo, and one in three compared with conventional antiemetics would have preferred to receive cannabinoids again. Before a chemical compound can be recommended for medical use, both its efficacy and safety must be proved. Cannabinoids were more effective than conventional antiemetics prochlorperazine, metoclopramide.
Of cancer patients treated with oral cannabinoids during chemotherapy, 16 will not be nauseated number needed to treat 6. Compared with placebo, cannabinoids were obviously better, although a placebo may not be an adequate comparator in patients having chemotherapy. We could not establish a dose-response relation, mainly because there were insufficient quality data from the original trials.
In some trials, dose was adjusted during the trial. In one trial, antiemetic efficacy was related to the plasma concentration of dronabinol.
Defining an intervention's usefulness includes estimates of the likelihood for harm. The physical and neuropsychiatric adverse effects of long term use of cannabis are well established, based mainly on observations from long term marijuana smokers.
Some adverse effects occurred almost exclusively with cannabinoid exposure. The number of patients withdrawing from the studies due to intolerable side effects is the most reliable parameter of the severity of cannabinoid related toxicity. One in eleven patients treated with cannabinoids will stop treatment who would not have stopped treatment had they taken a placebo or another antiemetic.
