Cannabis can sometimes relieve nausea more effectively than If there is no clear trigger for nausea, a patient should work with their doctor to. The anti-emetic effect of cannabinoids has been shown across a wide variety of A major advance in the control of acute emesis in chemotherapy treatment .. Early work suggested that anti-nausea agents interfered with the expression of. Cannabinoids and How They Work to Reduce Nausea and Vomiting. There are two cannabinoids that may help control nausea and vomiting.
CBD to Does Nausea? Work How Fight
Rats administered with an emetic drug which only makes them nauseous, as rats are unable to vomit were also administered CBD, and it was found that any behavior indicating nausea was effectively eliminated, or strongly inhibited.
It was a direct success, significantly decreasing the vomiting which occurred in the shrews. This led the researchers to conclude that the combination of THC and CBDa at sub-threshold doses was an effective antiemetic, and could be used for therapeutic purposes.
This is one of the most undesirable yet obnoxiously consistent side effects of chemotherapy. With many chemo patients describing the rapid onset CINV experience as overpowering , a plethora of antiemetics have been produced to combat the condition.
The 5-HT3 antagonists -setrons are the most common, those being:. Furthermore, the corticosteroid dexamethasone is somewhat effective in treating CINV.
Many other drug classes treat CINV:. So, pretty much everything. Nothing quite compares to cannabinoids, however. As you can see, there is strong overlap with the rat and shrew studies in terms of cannabinoid effects on nausea.
These are typically very effective, but can carry side effects. Cannabinoid Hyperemesis Syndrome , or CHS , is a paradoxical and poorly understood affliction sometimes induced in long-time cannabis users. Considering the widespread use of cannabis for treating symptoms such as chronic nausea, CINV, and morning sickness, the very existence of CHS seems absurd.
Despite this, a number of studies have shown that CHS can exist in long-time cannabis users, typically resolving following cessation. It is extremely unlikely to be inflicted with CHS:. Research into this is only beginning, however.
Cannabis contains over cannabinoids, and we have only studied four of them for nausea specifically. Perhaps with the advent of new breakthroughs in cannabis, such as the possible discovery of the CB3 receptor, and with more support and funding towards cannabis as a whole, we could put an end to unneeded nausea altogether.

Cannabinoid agonists have been shown to reduce vomiting in cats McCarthy and Borison, , pigeons Feigenbaum et al. The mechanism of action of the suppression of nausea and vomiting produced by cannabinoids has recently been explored with the discovery of the endocannabinoid system and the development of animal models of nausea and vomiting.
Recent reviews on the gastrointestinal effects of cannabinoids have concluded that cannabinoid agonists act mainly via peripheral CB 1 receptors to decrease intestinal motility Pertwee, , but may act centrally to attenuate emesis Van Sickle et al. The dorsal vagal complex DVC is involved in the vomiting reactions induced by either vagal gastrointestinal activation or several humoral cytotoxic agents.
The DVC is considered to be the starting point of a final common pathway for the induction of emesis in vomiting species. Endogenous cannabinoid ligands, such as anandamide and 2-arachidonyol glycerol 2-AG , as well as synthetic cannabinoids, such as WIN 55,—2, also act on these receptors Simoneau et al.
Although anandamide has been reported to have anti-emetic properties in the ferret Van Sickle et al. Darmani found that 2-AG 2. An evaluation of changes in endocannabinoid levels elicited by cisplatin revealed that cisplatin increased levels of 2-AG in the brainstem, but decreased intestinal levels of both 2-AG and anandamide Darmani et al. On the other hand, Van Sickle et al. CB 2 receptors in the brainstem may play a role in the regulation of emesis by 2-AG, at least when CB 1 receptors are co-stimulated.
The anti-emetic effects of 2-AG 0. Although inhibition of FAAH elevates multiple endocannabinoid-like molecules that show activity at multiple target receptors, the anti-emetic effects of URB were reversed by pretreatment with rimonabant, indicating a CB 1 mechanism of action. In experiments with the S. A relative of the cannabinoid system, vanilloid TRPV1 receptors have recently been shown to regulate emesis in the ferret Sharkey et al.
The TRPV1 receptor is targeted by capsaicin the burning component of chili peppers as well as resiniferatoxin, which can produce pro-emetic and anti-emetic effects at similar doses in S. Recent findings indicate that the cannabinoid system interacts with the 5-hydroxytryptaminergic system in the control of emesis e.
The first evidence of an interaction between cannabinoids and 5-HT 3 receptors was revealed by the finding that anandamide, WIN55 and CP inhibit 5-HT 3 receptor-mediated inward currents with IC 50 values in the nanomolar concentration range in rat nodose ganglion cells Fan, Since WIN 55,—2 did not displace a 5-HT 3 antagonist [ 3 H]-GR from the ligand binding site, the results suggest that cannabinoids inhibit 5-HT 3A receptors noncompetitively by binding to an allosteric modulatory site of the receptor Barann et al.
Additionally, cannabinoids have been shown to reduce the ability of 5-HT 3 agonists to produce emesis Darmani and Johnson, and this effect was prevented by pretreatment with rimonabant. Cannabinoids may act at CB 1 presynaptic receptors to inhibit the release of newly synthesized 5-HT Schlicker and Kathmann, ; Howlett et al.
Indeed, Darmani et al. Another major cannabinoid found in marijuana is CBD. As has been reported by others e. A wide range of doses was not effective in reducing motion-induced emesis in the S.
The anti-emetic effect of CBD does not appear to be mediated by its action at CB 1 receptors, because it is not reversed by the CB 1 antagonist, rimonabant Kwiatkowska et al. Indeed, Russo et al. Recently, our laboratory has investigated the mechanism of action for the anti-emetic effects of CBD. This activation of the 5-HT 1A receptors results in a reduction of the rate of firing of 5-HT neurones, ultimately reducing the release of forebrain 5-HT Blier and de Montigny, In addition, a recent finding suggests that CBD may also act as an allosteric modulator of the 5-HT 3 receptor Yang et al.
These findings suggest that allosteric inhibition of 5-HT 3 receptors by CBD may also contribute to its role in the modulation of emesis. Nausea is more resistant to effective treatment with new anti-emetic agents than is vomiting e.
Andrews and Horn, and therefore remains a significant problem in chemotherapy treatment and as a side effect from other pharmacological therapies, such as anti-depressants. Even when the cisplatin-induced emetic response is blocked in the ferret by administration of a 5-HT 3 receptor antagonist, c-fos activation still occurs in the AP, suggesting that an action here may be responsible for some of the other effects of cytotoxic drugs, such as nausea or reduced food intake Reynolds et al.
In rats, the gastric afferents respond in the same manner to physical and chemical intragastric copper sulphate and cisplatin stimulation that precedes vomiting in ferrets, presumably resulting in nausea that precedes vomiting Hillsley and Grundy, ; Billig et al.
Furthermore, 5-HT 3 antagonists that block vomiting in ferrets also disrupt this preceding neural afferent reaction in rats. That is, in the rat the detection mechanism of nausea is present, but the vomiting response is absent. Nauseogenic doses of cholecystokinin and LiCl induce specific patterns of brainstem and forebrain c-fos expression in ferrets that are similar to c-fos expression patterns in rats Reynolds et al.
In a classic review paper, Borrison and Wang suggest that the rats' inability to vomit can be explained as a species-adaptive neurological deficit and that, in response to emetic stimuli, the rat displays autonomic and behavioural signs corresponding to the presence of nausea, called the prodromata salivation, papillary dilation, tachypnoea and tachycardia.
The typical measure used in the literature to evaluate the nauseating potential of a drug is conditioned taste avoidance. However, taste avoidance is not only produced by nauseating doses of drugs, it is also produced by drugs that animals choose to self-administer or that establish a preference for a distinctive location e.
Berger, ; Wise et al. In fact, when a taste is presented prior to a drug self-administration session, the strength of subsequent avoidance of the taste is a direct function of intake of the drug during the self-administration session Wise et al.
This paradoxical phenomenon was initially interpreted as another instance of taste aversion learning. Because Garcia et al. However, in an animal capable of vomiting, the S. Since rats are incapable of vomiting, it is likely that conditioned taste avoidance produced by rewarding drugs in this species is based upon a learned fear of anything that changes their hedonic state e.
Gamzu, when that change is paired with food previously eaten. Another approach to understanding the role that nausea plays in the establishment of taste avoidance in rats is to evaluate the potential of anti-nausea treatments to interfere with avoidance of a flavour paired with an emetic treatment.
Early work suggested that anti-nausea agents interfered with the expression of previously established taste avoidance produced by LiCl Coil et al. Furthermore, there is considerable evidence that anti-nausea treatments either do not interfere with the establishment of conditioned taste avoidance learning Rabin and Hunt, ; Rudd et al. Two prominent anti-nausea treatments include drugs that reduce 5-HT availability and drugs that elevate the activity of the endocannabinoid system in rats see Parker et al.
Over the past number of years, our laboratory has provided considerable evidence that conditioned nausea in rats may be displayed as conditioned disgust reactions Parker, ; ; ; ; Limebeer and Parker, ; ; Limebeer et al. Rats display a distinctive pattern of disgust reactions including gaping, chin rubbing and paw treading when they are intraorally infused with a bitter tasting quinine solution.
Rats also display this disgust pattern when infused with a sweet tasting solution that normally elicits hedonic reactions of tongue protrusions that has previously been paired with a drug that produces vomiting such as LiCl or cyclophosphamide in species capable of vomiting. Only drugs with emetic properties produce this conditioned disgust reaction when paired with a taste.
The most reliable conditioned disgust reaction in the rat is that of gaping Breslin et al. If conditioned gaping reflects nausea in rats, then anti-nausea drugs should interfere with this reaction.
Limebeer and Parker demonstrated that when administered prior to a saccharin-LiCl pairing, the 5-HT 3 antagonist, ondansetron, prevented the establishment of conditioned gaping in rats, presumably by interfering with LiCl-induced nausea. Since ondansetron did not modify unconditioned gaping elicited by bitter quinine solution, the effect was specific to nausea-induced gaping. Subsequently, Limebeer and Parker demonstrated a very similar pattern following pretreatment with the 5-HT 1A autoreceptor antagonist, 8-OH-DPAT, that also reduces 5-HT availability and serves as an anti-emetic agent in animal models.
Most recently, Limebeer et al. The orofacial characteristics of the rat gape are very similar to those of the shrew retch just before it vomits Parker, Indeed, Travers and Norgren suggest that the muscular movements involved in the gaping response mimic those seen in species capable of vomiting.
Using the conditioned gaping response as a measure of nausea in rats, we have demonstrated that a low dose 0. The potent agonist, HU 0. When administered 30 min prior to the conditioning trial, rimonabant did not produce conditioned gaping on its own, but it did potentiate the ability of LiCl to produce conditioned gaping. This same pattern has been reported in the emesis literature Van Sickle et al. Van Sickle et al. More compelling evidence that the endocannabinoid system may serve as a regulator of nausea is the recent finding that prolonging the duration of action of anandamide by pretreatment with URB, a drug that inhibits the enzyme FAAH, also disrupts the establishment of LiCl-induced conditioned gaping reactions in rats Cross-Mellor et al.
Rats pretreated with URB 0. Rats given the combination of URB 0. Although inhibition of FAAH produces an elevation of a variety of fatty acids that act at different receptors, the effect of URB on conditioned nausea was reversed by AM, indicating that it was mediated by CB 1 receptors. On the other hand, the silent CB 1 antagonists, AM and AM, which do not have inverse agonist properties, do not produce conditioned gaping Sink et al.
In addition, the peripherally restricted silent CB 1 antagonist, AM, which also suppresses feeding at equivalent doses of AM Cluny et al.
Finally, neither the silent antagonist, AM which crosses the blood—brain barrier nor AM with limited CNS penetration , potentiate LiCl-induced nausea, an effect evident with low doses 2. AMinduced conditioned nausea is thus mediated by inverse agonism of the CB 1 receptor. Recent research Rock et al. Research aimed at determining the forebrain regions e. AN often develops over the course of repeated chemotherapy sessions Nesse et al.
For instance, Nesse et al. He experienced the same nausea when returning for routine follow-up visits, even though he knew he would not receive treatment.
The nausea gradually disappeared over repeated follow-up visits. AN is best understood as a classically conditioned response CR Pavlov, Control over AN could be exerted at the time of conditioning or at the time of re-exposure to the conditioned stimulus CS.
If an anti-emetic drug is presented at the time of conditioning, then a reduction in AN would be the result of an attenuated unconditioned response UCR ; that is, reduced nausea produced by the toxin at the time of conditioning thereby attenuating the establishment of the CR.
Indeed, when administered during the chemotherapy session, the 5-HT 3 antagonist, granisetron, has been reported to reduce the incidence of AN in repeat cycle chemotherapy treatment Aapro et al. On the other hand, if a drug is delivered prior to re-exposure to cues previously paired with the toxin-induced nausea, then suppressed AN would be the result of attenuation of the expression of the CR conditioned nausea ; the 5-HT 3 antagonists are ineffective at this stage Nesse et al.
Although there has been considerable experimental investigation of unconditioned retching and vomiting in response to toxins, there have been relatively few reports of conditioned retching; that is, emetic reactions elicited by re-exposure to a toxin paired cue. Conditioned retching has been observed to occur in coyotes, wolves and hawks upon re-exposure to cues previously paired with lithium-induced toxicosis Garcia et al.
This effect was replicated more recently and extended to demonstrate that CBD also interferes with the expression of conditioned retching in the shrew, but the 5-HT 3 antagonist ondansetron was completely ineffective Parker et al.
The doses employed were selected on the basis of their potential to interfere with toxin-induced vomiting in the S. Rats also display conditioned gaping reactions when re-exposed to a context previously paired with LiCl-induced nausea Limebeer et al.
Following four pairings of a distinctive, vanilla odour-laced chamber with LiCl-induced illness, rats were returned to the context for 30 min and received a 1 min intraoral infusion of novel saccharin solution every 5 min. During the infusions, the rats displayed gaping reactions. Surprisingly, the rats also gaped during intervals when they were not being infused with saccharin while in the LiCl-paired context.
The finding that rats express conditioned gaping responses when re-exposed to an odour-laced context previously paired with LiCl during inter-infusion intervals Limebeer et al.
Meachum and Bernstein had previously shown the re-exposure to a lithium-paired odour cue elicited gaping reactions in rats.
Recently, Limebeer et al. Most recently, Rock et al. Indeed, inhibition of FAAH by URB also prevented the establishment of LiCl-induced conditioned gaping elicited by the contextual cues when administered 2 h prior to each conditioning trial. These results suggest that cannabinoid compounds may be effective agents in the treatment of AN in chemotherapy patients. Since the discovery of the mechanism of action of cannabinoids, our understanding of the role of the endocannabinoid system in the control of nausea and vomiting has greatly increased.
In theory, this might be related to the anti-seizure effects of some components of cannibis. At this date early , these are just anecdotes. Products that we have been told were helpful are "Charlotte's Web", "Watermelon Pucks", and "Anandahemp ".
The first is CBD oil, and can easily be ordered from the internet. The second contains some THC, and is not as readily available. As noted above, THC is approved by the FDA for treatment of nausea and vomiting associated with chemotherapy, and thus it is not surprising that "Watermelon Pucks" might be helpful in some people with dizziness.
To be very clear, I am not advocating for these products, but I am simply transmitting what patients are telling me. As of , cannabis was approved for medical use in roughly 27 states.
In Illinois, the Illinois Compassionate Use of Medical Cannabis Pilot Program requires physicians to certify the diagnosis of a debilitating condition or terminal illness for a qualifying patient seeking to apply for a medical cannabis registry identification card.
Whether or not a physician chooses to provide a written physician certification is up to the health care practitioner. More information is here: According to Fife et al , the system used in Illinois is the usual one used to handle the odd situation where the Federal government states that licensed physicians cannot legally prescribe herbal marijuana although they may prescribe nabilone or dronabinol.
Physicians can document that the patient has a medical condition that justifies the use of marijuana under that state's law.
Patients then may proceed to acquire the marijuana, under the particulars of the laws of their state. Nevertheless, certain institutions, including the Department of Veteran affairs, may have policies bannng physicians from discussing medical marijuana with their patients. An individual diagnosed with one or more debilitating conditions is eligible to apply for a medical cannabis registry identification card. The qualifying patient must obtain a written certification from a physician specifying their debilitating condition, unless they are a veteran receiving health services at a VA facility.
Veterans must submit one year of medical records from the VA facility where they receive services. Effective January 1, , the Act was amended to include eligibility for children under age 18 and to add seizure disorders to the list of debilitating conditions. On June 30, , the Act was amended Public Act to add Post-Traumatic Stress Disorder PTSD as a debilitating condition and to allow persons diagnosed with a terminal illness to apply for a medical cannabis registry identification card.
Qualifying patients must be diagnosed with a debilitating condition, as defined in the Compassionate Use of Medical Cannabis Pilot Program Act, to be eligible for a medical cannabis registry identification card in Illinois.
Marijuana and Cancer
While it is an effective cure for motion sickness specifically, it's unlikely that it will work in treating other causes of nausea. Researchers have. Here are seven health benefits of CBD oil that are backed by effects related to cancer treatment, like nausea, vomiting and pain. However, these are test-tube and animal studies, so they can only suggest what might work in people. have cancer-fighting properties, more research is needed to assess. So can CBD help with nausea? If this is an avenue you'd like to pursue, work with your doctor (and the laws of your state) to come up with a.
