This article examines the benefits and possible side effects of CBD oil. Recent research suggests that CBD oil may be useful for pain relief and other which it is possible to use to make creams or gels that people can apply. Marijuana has been used to treat pain as far back as B.C. (2). of marijuana, including CBD, are responsible for its pain-relieving effects. and THC is effective in treating pain related to multiple sclerosis and arthritis. There's a lot of ongoing research about the effects of CBD oil on rheumatoid arthritis after five weeks of use, a cannabis-based medication called Sativex reduced that the CBD gel reduced both joint pain and inflammation without any side effects. It is also possible to apply CBD oil topically and many cream and lotion.

Potential for adverse side-effects on activity levels or motor abilities stemming from CBD gel application were assessed by monitoring open-field exploratory behaviour of naive animals for 45 min prior to and directly after treatment. Irrespective of the amount of CBD applied onto the back of animals, no changes were detected for total time spent in either exploratory activity or resting Fig.
Two other specific exploratory activities acquired in the open-field test but not affected by CBD were rearing events in which the animals rise on their hindlimbs to explore the environment and the total distance travelled during the 45 min test data not shown.
After batch staining immunohistochemical methods, the intensity of immunofluorescence was determined using computer assisted quantification. The immunoreactivity for neuropeptide CGRP was significantly increased in the superficial dorsal horn of the spinal cord in the monoarthritis group.
Treatment with high doses of CBD 6. Immunocytochemical localization of inflammatory biomarkers. Quantification of pro-inflammatory biomarkers in the lumbar spinal cord and dorsal root ganglia DRG. Naive animals had low levels of OX42 expression in the spinal cord, a marker for activated microglia Fig. Outcomes of this study indicate that topical application of CBD gel is an effective treatment for reduction in inflammation and hypersensitivity associated with the rodent adjuvant-induced monoarthritis model.
Transdermal administration of CBD provided good blood absorption due to avoidance of first pass metabolism encountered by orally administered drugs. Similarly in this study, CBD plasma concentrations for rats dosed with 0. However, the highest dose, The lack of increased outcome for this highest CBD concentration was potentially due to maximally activated CBD effects or capacity-limit absorption and metabolism.
This would account for the flattened linear pharmacokinetic profile effect of the Spreading large quantities of gel directly on the skin over the joint itself was not feasible in this transdermal dosing paradigm and would provide opportunity for oral ingestion by the rats. Efficacy of transdermal CBD for reduction in inflammation-associated symptoms in adjuvant-induced monoarthritic animals was determined comparing knee joint circumference and other features.
Likewise, increased synovial membrane thickness was reduced by the 6. These results concur with previous studies showing orally administered CBD decreased inflammation Malfait et al. Decreased inflammation and reduction in secretions of pro-inflammatory and matrix-degrading effector molecules by the synovial cell connective tissue membrane lining the joints are important for symptomatic treatment of patients with rheumatoid arthritis.
Pro-inflammatory and matrix-degrading effector molecules produced in excess are primary contributors to cartilage degradation over time Ospelt et al. The improvement of pain scores provided by transdermal CBD is an indirect measure of joint inflammation and direct measure of function.
The PWL in response to noxious heat stimuli was optimal with both the 6. Analogous to the results presented here, the highest dose of CBD administered in that study also did not perform as well as the next lower dose. In the same study at 6 h post inflammation, CBD treatment with two orally administered lower doses, 5 and 7. Peripheral inflammation and hypersensitivity are reversed by pharmacological inactivation of both central and peripheral neurons and central microglia Sluka et al.
Although CBD is described as an attenuator of both mechanical and heat hypersensitivity induced by inflammatory and neuropathic pain models, the exact mechanism of action is as yet unknown Mechoulam and Hanus, ; Kress and Kuner, Unlike THC and related cannabinoids, phytocannabinoid-CBD, an important bioactive component of Cannabis sativa without psychotropic effect, is an antagonist of orphan G protein-coupled receptor 55 GPR55, a potential third metabotropic cannabinoid receptor without binding to CB1 and CB2 receptors Begg et al.
A particular focus has been on TRPA1 and TRPV1, two widely co-expressed ion channels found in CGRP expressing peptidergic nociceptors essential for neurogenic inflammation, oedema formation and inflammation-induced mechanical and thermal hypersensitivity Davis et al. Their activation by CBD in vitro results in desensitized responses following noxious stimulation with capsaicin or mustard oil, their respective agonists.
This mechanism potentially decreases neuropeptide expression Bisogno et al. In vivo absence or inhibition of TRPA1 results in reduced mechanical hypersensitivity in animal models of inflammation Petrus et al. Absence of TRPV1 in vivo reduces inflammation-induced swelling, thermal hypersensitivity and nociceptive behaviour in various pain models Caterina et al.
In naive animals, TRPV1 immunoreactivity is localized in nociceptive primary afferents innervating the knee joint. After inflammation, TRPV1 expression increases not only in primary afferents, but is detected in synoviocytes which secrete lubricating fluid into the synovial space and function as local immune cells Kochukov et al. Primary afferents are thus not only sensitized by peripheral release of pro-inflammatory cytokines, but are surrounded by cells that produce and release these molecules themselves.
Further studies are needed to identify specific receptors and mechanisms underlying the anti-inflammatory and anti-hyperalgesic effects of CBD.
Transdermal CBD application was successful in decreasing monoarthritis-associated increases of pro-inflammatory biomarkers in neuronal tissues.
In this study, the expression of CGRP in spinal cord was increased after peripheral inflammation as previously reported Sluka and Westlund, , and was decreased by high doses 6. Like other neuropeptides, CGRP is rapidly transported to nerve terminals for release centrally as well as peripherally where as a potent vasodilator it contributes to neurogenic inflammation Kawasaki et al. Although increases in CGRP are described in DRG after hindpaw inflammation Nahin and Byers, , no significant changes in DRG expression were observed here data not shown , possibly due to the small number of sensory neurons innervating the joint.
It is also plausible that by 7 days post monoarthritis induction, neuropeptide content has stabilized. In monoarthritic animals, spinal cord OX42 expression is increased in activated microglia, the immune cells specific to the central nervous system, as previously described for CFA-induced ankle inflammation and trinitrobenzene sulfonic acid TNBS -induced pancreatitis Shan et al.
Treatment with high doses of transdermal CBD in this study effectively reduced OX42 expression below baseline levels, indicating reduced microglial activation.
CBD is a known non-psychoactive cannabinoid, and due to its low affinity for the CB1 receptor it would be expected that exploratory behavioural activity would be similar among treatment groups compared to negative side-effects associated with THC Croxford, ; Malone et al. This was demonstrated in this study by lack of CBD-induced changes in open-field exploration among naive treatment groups. Combinatorial with psychoactivity, side-effects such as hypothermia and hypomobility induced by THC are avoided with use of CBD Zimmer et al.
These studies demonstrate transdermal administration of CBD has long-lasting therapeutic effects without psychoactive side-effects. Thus, use of topical CBD has potential as effective treatment of arthritic symptomatology.
The data presented suggest transdermal CBD is a good candidate for developing improved therapies for these debilitating disease. Stinchcomb, University of Kentucky start-up funds to K.

Abstract Background Current arthritis treatments often have side-effects attributable to active compounds as well as route of administration. Results Measurement of plasma CBD concentration provided by transdermal absorption revealed linearity with 0.
Conclusions These data indicate that topical CBD application has therapeutic potential for relief of arthritis pain-related behaviours and inflammation without evident side-effects. Introduction Almost 50 million Materials and methods 2. Open in a separate window. Conclusion These studies demonstrate transdermal administration of CBD has long-lasting therapeutic effects without psychoactive side-effects.
Cannabinoids and cannabinoid receptors have been studied as potential targets for reducing pain and inflammation associated with osteoarthritis and rheumatoid arthritis. Cannabinoid side-effects vary and depend on several factors like administrated dose, route of administration, etc. What does this study add? Transdermal cannabidiol CBD gel application has therapeutic potential for relief of arthritic pain-related behaviours and exerts an anti-inflammation property without evident high brain centre psychoactive effects.

Serum levels peak in 1—4 hours Lemberger et al It was also primarily developed as an anti-emetic in chemotherapy, and was recently re-approved for this indication in the USA. Prior case reports have noted analgesic effects in case reports in neuropathic pain Notcutt et al and other pain disorders Berlach et al Sedation and dysphoria were prominent sequelae.
An RCT of nabilone in 41 post-operative subjects actually documented exacerbation of pain scores after thrice daily dosing Beaulieu Table 1. An abstract of a study of 82 cancer patients on nabilone claimed improvement in pain levels after varying periods of follow-up compared to patients treated without this agent Maida However, 17 subjects dropped out, and the study was neither randomized nor controlled, and therefore is not included in Table 1.

Both Marinol and Cannador produced reductions in pain scores in long-term follow-up Zajicek et al Cannador was assayed in postherpetic neuralgia in 65 subjects with no observed benefit Ernst et al Table 1 , and in 30 post-operative pain subjects CANPOP without opiates, with slight benefits, but prominent psychoactive sequelae Holdcroft et al Table 1. It was approved by Health Canada in June for prescription for central neuropathic pain in multiple sclerosis, and in August , it was additionally approved for treatment of cancer pain unresponsive to optimized opioid therapy.
Sativex effects commence in 15—40 minutes, an interval that permits symptomatic dose titration. A very favorable adverse event profile has been observed in over patient years of exposure in over experimental subjects. Patients most often ascertain an individual stable dosage within 7—10 days that provides therapeutic relief without unwanted psychotropic effects often in the range of 8—10 sprays per day.
In a Phase II double-blind crossover study of intractable chronic pain Notcutt et al in 24 subjects, visual analogue scales VAS were 5. During that time, there was no escalation of dose indicating an absence of tolerance to the preparation. Similarly, no withdrawal effects were noted in a subset of patients who voluntarily stopped the medicine abruptly.
Upon resumption, benefits resumed at the prior established dosages. In a Phase II double-blind, randomized, placebo-controlled, 5-week study of 56 rheumatoid arthritis patients with Sativex Blake et al , employed nocturnal treatment only to a maximum of 6 sprays per evening In a study of spinal injury pain, NRS of pain were not statistically different from placebo, probably due to the short duration of the trial, but secondary endpoints were clearly positive Table 1.
Finally, in an RCT of intractable lower urinary tract symptoms in MS, accompanying pain in affected patients was prominently alleviated Table 1. Common adverse events AE of Sativex acutely in RCTs have included complaints of bad taste, oral stinging, dry mouth, dizziness, nausea or fatigue, but do not generally necessitate discontinuation, and prove less common over time.
While there have been no head-to-head comparative RCTs of Sativex with other cannabinoid agents, certain contrasts can be drawn. Sativex Rog et al and Marinol Svendsen et al have both been examined in treatment of central neuropathic pain in MS, with comparable results Table 1. However, adverse events were comparable or greater with Marinol than with Sativex employing THC dosages some 2.
Similarly, while Sativex and smoked cannabis have not been employed in the same clinical trial, comparisons of side effect profiles can be made on the basis of SAFEX studies of Sativex for over a year and up to several years in MS and other types of neuropathic pain Russo b ; Wade et al , and government-approved research programs employing standardized herbal cannabis from Canada for chronic pain Lynch et al and the Netherlands for general conditions Janse et al ; Gorter et al over a period of several months or more.
As is evident in Figure 2 Figure 2 , all adverse events are more frequently reported with herbal cannabis, except for nausea and dizziness, both early and usually transiently reported with Sativex see Russo b for additional discussion. Comparison of adverse events AE encountered with long term therapeutic use of herbal cannabis in the Netherlands Janse et al ; Gorter et al and Canada Lynch et al , vs that observed in safety-extension SAFEX studies of Sativex oromucosal spray Russo ; Wade et al Phytocannabinoids are lipid soluble with slow and erratic oral absorption.
While cannabis users claim that the smoking of cannabis allows easy dose titration as a function of rapid onset, high serum levels in a short interval inevitably result.
This quick onset is desirable for recreational purposes, wherein intoxication is the ultimate goal, but aside from paroxysmal disorders eg, episodic trigeminal neuralgia or cluster headache attack , such rapid onset of activity is not usually necessary for therapeutic purposes in chronic pain states.
The vast majority of subjects in Sativex clinical trials do not experience psychotropic effects outside of initial dose titration intervals Figure 2 and most often report subjective intoxication levels on visual analogue scales that are indistinguishable from placebo, in the single digits out of Wade et al Thus, it is now longer tenable to claim that psychoactive effects are a necessary prerequisite to symptom relief in the therapeutic setting with a standardized intermediate onset cannabis-based preparation.
Intoxication has remained a persistent issue in Marinol usage Calhoun et al , in contrast. Recent controversies have arisen in relation to non-steroidal anti-inflammatory drugs NSAID , with concerns that COX-1 agents may provoke gastrointestinal ulceration and bleeding, and COX-2 drugs may increase incidents of myocardial infarction and cerebrovascular accidents Fitzgerald ; Topol Frequent questions have been raised as to whether psychoactive drugs may be adequately blinded masked in randomized clinical trials.
Internal review and outside analysis have confirmed that blinding in Sativex spasticity studies has been effective Clark and Altman ; Wright Sativex and its placebo are prepared to appear identical in taste and color.
Great public concern attends recreational cannabis usage and risks of dependency. The addictive potential of a drug is assessed on the basis of five elements: Drug abuse liability DAL is also assessed by examining a drug's rates of abuse and diversion. US Congress placed cannabis in Schedule I of the Controlled Substances Act in , with drugs categorized as addictive, dangerous, possessing severe abuse potential and no recognized medical value.
Marinol was placed in Schedule II, the category for drugs with high abuse potential and liability to produce dependency, but certain recognized medical uses, after its FDA approval in Marinol was reassigned to Schedule III in , a category denoting a lesser potential for abuse or lower dependency risk after documentation that little abuse or diversion Calhoun et al had occurred.
Nabilone was placed and has remained in Schedule II since The degree to which a drug is reinforcing is determined partly by the by the rate of its delivery to the brain Samaha and Robinson Sativex has effect onset in 15—40 minutes, peaking in a few hours, quite a bit slower than drugs of high abuse potential. It has been claimed that inclusion of CBD diminishes psychoactive effects of THC, and may lower potential drug abuse liability of the preparation see Russo b for discussion.
Prior studies from Sativex clinical trials do not support the presence reinforcement or euphoria as problems in administration Wade et al Certain facets of acute cannabinoid exposure, including tachycardia, hypothermia, orthostatic hypotension, dry mouth, ocular injection, intraocular pressure decreases, etc.
No dose tolerance to the therapeutic effects of Sativex has been observed in clinical trials in over patient-years of administration. Additionally, therapeutic efficacy has been sustained for several years in a wide variety of symptoms; SAFEX studies in MS and peripheral neuropathic pain, confirm that Sativex doses remain stable or even decreased after prolonged usage Wade et al , with maintenance of therapeutic benefit and even continued improvement.
Debate continues as to the existence of a clinically significant cannabis withdrawal syndrome with proponents Budney et al , and questioners Smith While symptoms recurred after 7—10 days of abstinence from Sativex, prior levels of symptom control were readily re-established upon re-titration of the agent Wade et al Overall, Sativex appears to pose less risk of dependency than smoked cannabis based on its slower onset, lower dosage utilized in therapy, almost total absence of intoxication in regular usage, and minimal withdrawal symptomatology even after chronic administration.
No known abuse or diversion incidents have been reported with Sativex to date as of November Cognitive effects of cannabis have been reviewed Russo et al ; Fride and Russo , but less study has occurred in therapeutic contexts. Effects of chronic heavy recreational cannabis usage on memory abate without sequelae after a few weeks of abstinence Pope et al Studies of components of the Halstead-Reitan battery with Sativex in neuropathic pain with allodynia have revealed no changes vs placebo Nurmikko et al , and in central neuropathic pain in MS Rog et al , 4 of 5 tests showed no significant differences.
While the Selective Reminding Test did not change significantly on Sativex, placebo patients displayed unexpected improvement. Slight improvements were observed in Hospital Anxiety and Depression Scales depression and anxiety scores were noted with Sativex in MS patients with central neuropathic pain Rog et al , although not quite statistically significant.
No long-term mood disorders have been associated with Sativex administration. Debate continues with regard to the relationship between cannabis usage and schizophrenia reviewed Fride and Russo An etiological relationship is not supported by epidemiological data Degenhardt et al , but if present, should bear relation to dose and length of high exposure.
It is likely that lower serum levels of Sativex in therapeutic usage, in conjunction with anti-psychotic properties of CBD Zuardi and Guimaraes , would minimize risks. Children and adolescents have been excluded from Sativex RCTs to date. SAFEX studies of Sativex have yielded few incidents of thought disorder, paranoia or related complaints.
Adverse effects of cannabinoids on immune function have been observed in experimental animals at doses 50— times the psychoactive level Cabral In four patients using herbal cannabis therapeutically for over 20 years, no abnormalities were observed in leukocyte, CD4 or CD8 cell counts Russo et al Investigation of MS patients on Cannador revealed no major immune changes Katona et al , and similarly, none occurred with smoked cannabis in a short-term study of HIV patients Abrams et al Hematological measures have been normal in all Sativex RCTs without clinical signs of immune dysfunction.
Concerns are frequently noted with new drug-drug interactions, but few have resulted in Sativex RCTs despite its adjunctive use with opiates, many other psychoactive analgesic, antidepressant and anticonvulsant drugs Russo a , possibly due to CBD ability to counteract sedative effects of THC Nicholson et al Thus, Sativex should be safe to use in conjunction with other drugs metabolized via this pathway. The Sativex product monograph in Canada http: Given that THC is the most active component affecting such abilities, and the low serum levels produced in Sativex therapy vide supra , it would be logical that that patients may be able to safely engage in such activities after early dose titration and according to individual circumstances, much as suggested for oral dronabinol.
This is particularly the case in view of a report by an expert panel Grotenhermen et al that comprehensively analyzed cannabinoids and driving. Prior studies document that 4 rapid oromucosal sprays of Sativex greater than the average single dose employed in therapy produced serum levels well below this threshold Russo b.
Sativex is now well established as a cannabinoid agent with minimal psychotropic effect. These include anti-emetic effects, well established with THC, but additionally demonstrated for CBD Pertwee , the ability of THC and CBD to produce apoptosis in malignant cells and inhibit cancer-induced angiogenesis Kogan ; Ligresti et al , as well as the neuroprotective antioxidant properties of the two substances Hampson et al , and improvements in symptomatic insomnia Russo et al The degree to which cannabinoid analgesics will be adopted into adjunctive pain management practices currently remains to be determined.
Given their multi-modality effects upon various nociceptive pathways, their adjunctive side benefits, the efficacy and safety profiles to date of specific preparations in advanced clinical trials, and the complementary mechanisms and advantages of their combination with opioid therapy, the future for cannabinoid therapeutics appears very bright, indeed.
