Does Fight Nausea? How CBD Help Oil
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 the ferret and shrew models, the site of action has been identified in the emetic area of the brainstem, the DVC. The shrew model, in particular, is cost effective for the evaluation of the anti-emetic properties of agents.
The conditioned gaping response in the rat has provided a glimpse into the anti-nausea mechanisms of action of cannabinoids, in the absence of a vomiting response. Since nausea is a more difficult symptom to control than vomiting, the gaping model may serve as a useful tool for the development of new anti-nausea treatments, as well as for the evaluation of the potential side effects of nausea in newly developed pharmacological treatments. Recent work has also supported anecdotal reports that cannabis may attenuate AN.
Although chemotherapy-induced vomiting is well controlled in most patients by conventionally available drugs, nausea acute, delayed and anticipatory continues to be a challenge. Nausea is often reported as more distressing than vomiting, because it is a continuous sensation e. Both preclinical and human clinical e.
Animal models of vomiting have been valuable in elucidating the neural mechanisms of the emetic reflex e. Hornby, ; however, the neural mechanisms of nausea are still not well understood Andrews and Horn, One limitation in the preclinical screening of the nauseating side effect of compounds and the potential of compounds to treat nausea has been the lack of a reliable preclinical rodent model of nausea.
For years researchers have been using conditioned taste avoidance in rats as a model of nausea, but it has been well documented that non-nauseating treatments also produce taste avoidance — it is not a selective measure of nausea e. However, the considerable amount of evidence reviewed above indicates that conditioned disgust in rats elicited by an illness-paired flavour e.
This model may be a useful tool for elucidating the neurobiology of nausea and the role that the endocannabinoid system plays in the regulation of this distressing condition.

Nausea is having the feeling or urge to vomit. In some cases, nausea can be debilitating and lead to vomiting, which means to forcefully throw-up the contents of the stomach out through the mouth.
Nausea and vomiting both play an important defensive role by rejecting the ingestion or digestion of potentially harmful substances. For example, nausea and vomiting can prevent the body from keeping down much-needed medications intended to treat serious conditions.
If a patient has previously gotten sick numerous times following treatment, for example, the smells, sights and sounds of the treatment room can trigger nausea even before treatment has begun.
Controlling nausea is important for allowing patients to continue their necessary medical treatment and to have a better quality of life. Not controlling nausea and vomiting can lead to chemical changes in the body, mental changes, loss of appetite, malnutrition, dehydration, a torn esophagus, broken bones and reopening of surgical wounds.
In addition, nausea can cause longer hospital stays, difficulty handling everyday activities, lost work hours and depression.
Cannabis has long been known to limit or prevent nausea and vomiting from a variety of causes 5,8. The major cannabinoids within cannabis, tetrahydrocannabinol THC and cannabidiol CBD , have both been shown effective at regulating nausea and vomiting because they interact with cannabinoid receptor 1 CB 1 of the endocannabinoid system. Activating the CB 1 receptor suppresses vomiting 4. For patients suffering from nausea following cancer treatments , cannabis has shown it can provide relief.
Studies have found that cannabinoids, including CBD contained in cannabis, are effective at treating the more difficult to control symptoms of nausea, as well as preventing anticipatory nausea in chemotherapy patients 6. Another study found that THC was also effective at reducing conditioned rejection and chemotherapy-induced nausea 1. Currently, 19 states have approved medical cannabis specifically for the treatment of nausea. A couple of other states will consider allowing medical cannabis to be used for the treatment of nausea with the recommendation by a physician.
