Could the cannabis-based medicine CBD oil be the cure for pain? (CBD) oil has steadily gained popularity as a natural approach to pain relief. touted as an alternative to pain medication in the treatment of common conditions like arthritis . Research confirms cannabinoids as potent painkillers and anti-inflammatory These events are natural reactions of our body triggering a patients in testing CBD as a substitute for ibuprofen or other pain-control and anti-inflammatory drugs. Along with CBD oils, there are capsules, sublingual tinctures. CBD as a natural and safe alternative treatment for pain is becoming into the spotlight as an excellent natural alternative to prescription pain medication. A convenient way to use CBD for pain management is with CBD oil.

CBD may offer an option for treating different types of chronic pain. A study from the European Journal of Pain showed, using an animal model, CBD applied on the skin could help lower pain and inflammation due to arthritis.
Another study demonstrated the mechanism by which CBD inhibits inflammatory and neuropathic pain, two of the most difficult types of chronic pain to treat. More study in humans is needed in this area to substantiate the claims of CBD proponents about pain control.
Side effects of CBD include nausea, fatigue and irritability. CBD can increase the level in your blood of the blood thinner coumadin, and it can raise levels of certain other medications in your blood by the exact same mechanism that grapefruit juice does. A significant safety concern with CBD is that it is primarily marketed and sold as a supplement, not a medication. Currently, the FDA does not regulate the safety and purity of dietary supplements.
So you cannot know for sure that the product you buy has active ingredients at the dose listed on the label. In addition, the product may contain other unknown elements. Some CBD manufacturers have come under government scrutiny for wild, indefensible claims, such that CBD is a cure-all for cancer, which it is not. We need more research but CBD may be prove to be an option for managing anxiety, insomnia, and chronic pain.
Should one take as gospel the equivalencies between CBD and Grapefruit juice? Omeprazole is pretty safe, by and large; I think the biggest concern with CBD would be with medications where an altered, irregular dosage could be dangerous, such as blood thinners…. I suffered two concussions within a space of 7 weeks: That was about 18 months ago and I still suffer from post-concussion syndrome, which is barely tolerable. Hyper-sensitivity to light and sound, exhaustion, some dizziness, some cognitive impairment.
I hesitate to try anything that might further impair my cognitive function but I am willing to give cannabis a try now that it is legal in Canada.
There is some evidence that cannabis is neuroprotective, and can help protect against Traumatic Brain Injury: It looks like if one has THC in their system prior to the trauma, some of the damage might be mitigated. Am I wrong on this? I just started cbd oil and want to learn everything I can about it. I need some clarification here.
However, I do want to know,what you base these claims on? Thank you for your questions. Marijuana and hemp are two extremely different strains of the same cannabis sativa plant that have been bred over thousands of years to have entirely different purposes. Hemp is not the male version of the marijuana plant. They both contain CBD. Any medicine can have different effects on different people. For example, Benadryl makes some people sleepy yet can make others wide-awake.
So, it is not inconsistent for a particular medicine to cause a symptom in one person and to help alleviate it in another. I can concur based on real time experience with my Mother who is bed bound with an irreparable fracture to her hip prosthesis. She also eats gluten free muffins containing the oil. She thoroughly enjoys her alternatives and requests them regularly.
Thank you for your comment. It is fantastic that she is able to reduce her use of opioids. But for those struggling with chronic pain conditions, things get expensive fast. CBD oil, on the other hand, is a more affordable option. More or less can be taken depending on the pain levels being experienced that day, and can be stopped and started as needed. Lighter or stronger doses are available as well. What this means to you is that you should be extra careful in finding a reputable, high-quality brand from people you trust.
This might be our team at Apple Wellness, a local supplement store near you, a medical practitioner, chiropractor, or naturopath. Just do your research first. Please remember, we are not advising anyone to stop, start, or alter any medically prescribed medications without first consulting a licensed medical practitioner. People suffering from chronic pain frequently experience additional health issues related to pain.
Some additional medical benefits of CBD oil include relief for the following common side effects of chronic pain: Your first priority is to find a high-quality brand of CBD oil. The best CBD oil equals the best results. Think about coffee — some respond a lot to just a little, while other people can seem to drink a gallon without batting an eye.
All of our bodies process in different ways. Because of this, we recommend that when starting out with CBD oil, start small and start slow. Gradually increase until you feel the results. Keep in mind; it can sometimes take a couple of hours for CBD oil to kick in. Take your CBD oil with or without food, in water, or right under your tongue.

The ECS also mediates central stress-induced analgesia Hohmann et al , and is active in nociceptive spinal areas Hohmann et al ; Richardson et al a including mechanisms of wind-up Strangman and Walker and N-methyl-D-aspartate NMDA receptors Richardson et al b. It was recently demonstrated that cannabinoid agonists suppress the maintenance of vincristine-induced allodynia through activation of CB 1 and CB 2 receptors in the spinal cord Rahn et al The ECS is also active peripherally Richardson et al c where CB 1 stimulation reduces pain, inflammation and hyperalgesia.
These mechanisms were also proven to include mediation of contact dermatitis via CB 1 and CB 2 with benefits of THC noted systemically and locally on inflammation and itch Karsak et al Recent experiments in mice have even suggested the paramount importance of peripheral over central CB 1 receptors in nociception of pain Agarwal et al Cannabinoid agonists produce many effects beyond those mediated directly on receptors, including anti-inflammatory effects and interactions with various other neurotransmitter systems previously reviewed Russo a.
Briefly stated, THC effects in serotonergic systems are widespread, including its ability to decrease 5-hydroxytryptamine 5-HT release from platelets Volfe et al , increase its cerebral production and decrease synaptosomal uptake Spadone THC may affect many mechanisms of the trigeminovascular system in migraine Akerman et al ; Akerman et al ; Akerman et al ; Russo ; Russo The glutamatergic system is integral to development and maintenance of neuropathic pain, and is responsible for generating secondary and tertiary hyperalgesia in migraine and fibromyalgia via NMDA mechanisms Nicolodi et al Additionally, cannabinoids reduce hyperalgesia via inhibition of calcitonin gene-related peptide Richardson et al a.
As for Substance P mechanisms, cannabinoids block capsaicin-induced hyperalgesia Li et al , and THC will do so at sub-psychoactive doses in experimental animals Ko and Woods These are all promising attributes for an adjunctive agent in treatment of clinical chronic pain states.
The anti-inflammatory contributions of THC are also extensive, including inhibition of PGE-2 synthesis Burstein et al , decreased platelet aggregation Schaefer et al , and stimulation of lipooxygenase Fimiani et al THC has twenty times the anti-inflammatory potency of aspirin and twice that of hydrocortisone Evans , but in contrast to all nonsteroidal anti-inflammatory drugs NSAIDs , demonstrates no cyclo-oxygenase COX inhibition at physiological concentrations Stott et al a.
Cannabidiol, a non-euphoriant phytocannabinoid common in certain strains, shares neuroprotective effects with THC, inhibits glutamate neurotoxicity, and displays antioxidant activity greater than ascorbic acid vitamin C or tocopherol vitamin E Hampson et al These activities reinforce the conception of CBD as an endocannabinoid modulator, the first clinically available Russo and Guy CBD additionally affects THC function by inhibiting first pass hepatic metabolism to the possibly more psychoactive hydroxy-THC, prolonging its half-life, and reducing associated intoxication, panic, anxiety and tachycardia Russo and Guy A new explanation of inflammatory and analgesic effects of CBD has recently come to light with the discovery that it is able to promote signaling of the adenosine receptor A2A by inhibiting the adenosine transporter Carrier et al Cannabichromene CBC is the third most prevalent cannabinoid in cannabis, and is also anti-inflammatory Wirth et al , and analgesic, if weaker than THC Davis and Hatoum Furthermore, CBG has more potent analgesic, anti-erythema and lipooxygenase blocking activity than THC Evans , mechanisms that merit further investigation.
It requires emphasis that drug stains of North American ElSohly et al ; Mehmedic et al , and European King et al cannabis display relatively high concentrations of THC, but are virtually lacking in CBD or other phytocannabinoid content.
Cannabis terpenoids also display numerous attributes that may be germane to pain treatment McPartland and Russo Myrcene is analgesic, and such activity, in contrast to cannabinoids, is blocked by naloxone Rao et al , suggesting an opioid-like mechanism. It also blocks inflammation via PGE-2 Lorenzetti et al It is anti-inflammatory comparable to phenylbutazone via PGE-1 Basile et al , but simultaneously acts as a gastric cytoprotective Tambe et al Cannabis flavonoids in whole cannabis extracts may also contribute useful activity McPartland and Russo Cannflavin A, a flavone unique to cannabis, inhibits PGE-2 thirty times more potently than aspirin Barrett et al , but has not been subsequently investigated.
Very few randomized controlled trials RCTs have been conducted using smoked cannabis Campbell et al despite many anecdotal claims Grinspoon and Bakalar A recent brief trial of smoked cannabis 3. This short clinical trial also demonstrated prominent adverse events associated with intoxication. In Canada, 21 subjects with chronic pain sequentially smoked single inhalations of 25 mg of cannabis 0, 2.
Even after political and legal considerations, it remains extremely unlikely that crude cannabis could ever be approved by the FDA as a prescription medicine as outlined in the FDA Botanical Guidance document Food and Drug Administration ; Russo b , due to a lack of rigorous standardization of the drug, an absence of Phase III clinical trials, and pulmonary sequelae bronchial irritation and cough associated with smoking Tashkin Although cannabis vaporizers reduce potentially carcinogenic polyaromatic hydrocarbons, they have not been totally eliminated by this technology Gieringer et al ; Hazekamp et al Two open label studies in France of oral dronabinol for chronic neuropathic pain in 7 subjects Clermont-Gnamien et al and 8 subjects Attal et al , respectively, failed to show significant benefit on pain or other parameters, and showed adverse event frequently requiring discontinuation with doses averaging 15— Dronabinol did demonstrate positive results in a clinical trial of multiple sclerosis pain in two measures Svendsen et al , but negative results in post-operative pain Buggy et al Table 1.
Another uncontrolled case report in three subjects noted relief of intractable pruritus associated with cholestatic jaundice employing oral dronabinol Neff et al Some authors have noted patient preference for whole cannabis preparations over oral THC Joy et al , and the contribution of other components beyond THC to therapeutic benefits McPartland and Russo THC absorption orally is slow and erratic with peak serum levels in 45— minutes or longer.
Systemic bioavailability is also quite low due to rapid hepatic metabolism on first pass to hydroxy-THC. A rectal suppository of THC-hemisuccinate is under investigation Broom et al , as are transdermal delivery techniques Challapalli and Stinchcomb The terminal half-life of THC is quite prolonged due to storage in body lipids Grotenhermen Nabilone Cesamet Figure 1 , is a synthetic dimethylheptyl analogue of THC British Medical Association that displays greater potency and prolonged half-life.
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. Part of its analgesic activity may relate to binding to intracellular peroxisome proliferator-activator receptor gamma Liu et al Peak plasma concentrations have generally been attained in 1—2 hours, but with delays up to 4—5 hours is some subjects Karst et al Debate surrounds the degree of psychoactivity associated with the drug Dyson et al Current research is confined to the indication of interstitial cystitis.
CBD ratios reviewed in Russo and Guy , generally approximately 2: Two pharmacokinetic studies on possibly related material have been reported Nadulski et al a ; Nadulski et al b. 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.
Which is Better for Pain Management: Opioids or CBD?
These pain relievers are not nearly as safe as cannabis. Medical marijuana is becoming a popular alternative to over-the-counter and prescription painkillers, and the whole cannabis plant, with CBD, THC, and the natural medley of . or you would like pain relief without any “high” feeling, CBD oil may. Alternative pain treatments like hemp oil have shown a lot of promise for people People have been looking into alternative pain medication for a long time – in and frankincense have been used for a long time as natural therapies for pain. As a natural pain-relief drug, some experts consider cannabis more suitable for Medical supplements can be pure THC, pure CBD or, so called 'full-spectrum products' like CBD oil, It also offers more benefit while providing similar pain- relief effects. . What exactly it is reacting with from what I, prescribed I'm now sure.
