CBD for Sciatica: A Look Into the Potential Treatment for Chronic Pain
Though science hasn’t gotten far when it comes to using CBD for sciatica, results from existing studies show CBD can help diminish neuropathic pain and inflammation caused by this condition.
The studies primarily include research performed with Sativex, a drug that contains both CBD (non-psychoactive) and THC (the psychoactive component of cannabis).
Clinical research found that Sativex is very effective for treating neuropathic pain in multiple sclerosis (MS) patients, and this medication is available for MS patients in Canada.
Studies That Confirm The Effectiveness of a CBD-Containing Drug
During this study from 2006, patients with multiple sclerosis were given Sativex in the form of a spray, and researchers found that 8-12 sprays per day significantly diminished symptoms of MS, most notably neuropathic pain and muscle spasticity.
Each spray of Sativex delivered 2.5 mg of CBD and 2.7 mg of THC, which in total comes to around 20~30 mg of CBD per day, and 22~32 mg of THC.
Researchers concluded that “Sativex is efficacious and well tolerated in the treatment of these symptoms”.
Researchers in a different study from 2007 summarized the efficacy and safety profile of Sativex for MS patients suffering from neuropathic pain, agreeing that cannabinoid-based medications are helpful:
“Cannabinoids including the cannabidiol/THC buccal spray are effective in treating neuropathic pain in MS.”
Finally, a 2008 study concurred that Sativex is beneficial for various types of pain:
“Numerous randomized clinical trials have demonstrated safety and efficacy for Sativex in central and peripheral neuropathic pain, rheumatoid arthritis and cancer pain.”
Even though the aforementioned studies were focusing on the effects of CBD and THC used together, there are several studies that indicate that the use of CBD alone can prove beneficial for various types of pain.
This 2012 research mentioned that the use of CBD significantly suppressed both neuropathic pain and chronic inflammation in rodents, without causing any apparent analgesic tolerance.
A review from 2013 noted that orally-ingested CBD appears to be a promising compound for the treatment of chronic inflammation and neuropathic pain.
An animal study from 2016 used CBD gel on rats with arthritis and found that a dose of 6.2 mg CBD per day significantly reduced inflammation and pain.
Conclusively, a 2018 scientific review mentioned that cannabidiol (CBD) is a very important chemical compound that may possess “significant analgesic, anti-inflammatory, anticonvulsant and anxiolytic activities.”
Besides the sensation of neural pain, sciatica is often accompanied with inflammation.
Multiple studies are showing that CBD directly lowers inflammation:
- Animal study from 2012 (for acute lung injury)
- Three studies from 2011 (for inflammation resulting from oxidative stress, chronic inflammation of the gut, and neural inflammation related to Alzheimer’s disease)
- Animal study from 2007 (for chronic inflammation and neuropathic pain)
One of the best anecdotal evidence showing CBD’s efficacy for sciatica comes from Brenda Davidson from Scotland. Esteemed UK newspaper Independent ran a story about her CBD treatment in 2017.
After suffering from debilitating sciatica for 13 years, she discovered CBD oil at the age of 55.
She mentioned in the interview that using CBD oil relieved the majority of her symptoms, and greatly helped her to reclaim her life.
How to Use CBD for Sciatica
There are three different methods of administration for sciatica, and they include:
- CBD oils
- CBD capsules
- CBD topicals (creams infused with CBD)
It’s important to know that CBD oils and topicals have a quicker onset of effects, while CBD capsules require more time.
Oils and topicals require about 15 minutes to start working, while capsules require 60~90 minutes.
As for CBD oils, a dose of oil should be placed under the tongue with a dropper that comes with the bottle.
The dose should be left under the tongue for one minute, so the sublingual veins can absorb the CBD. Any remaining oil should be swallowed.
CBD Dosage for Sciatica
A single dose in the range of 15 mg to 20 mg of CBD is usually adequate to relieve symptoms for most users, while some users require larger doses (40 mg or 60 mg).
Some people don’t experience any beneficial effects when they start using CBD. This isn’t completely understood, but a contemporary scientific hypothesis (called clinical endocannabinoid system deficiency) attempts to explain this occurrence.
This theory mentions that some people have a dysfunctional endocannabinoid system, which is an internal bodily system through which CBD creates the majority of its effects.
A dysfunctional endocannabinoid system makes CBD therapy somewhat difficult, but certainly not impossible.
Clinical endocannabinoid system deficiency hypothesis explains that a frequent exposure to cannabinoids like CBD progressively revitalizes the endocannabinoid system.
If you don’t experience any beneficial effects, continue using CBD on a daily basis to “restart” your endocannabinoid system. This process usually requires several weeks.
Possible Side Effects of CBD & Drug Interactions
While most users don’t experience any issues during their CBD treatment, a small percentage of consumers can experience side effects.
Reasons to why this occurs are still unclear, but a running hypothesis is that age, overall health and personal genetics of the user affect how they react to the treatment.
The main potential side effects of CBD include nausea, diarrhea, changes in body weight and appetite, and users who take large daily doses may also feel irritability and fatigue.
Another important aspect of CBD therapy is how this compound interacts with other drugs.
It’s crucial to note that products containing CBD can interfere with the metabolization (breakdown) of drugs that have a grapefruit warning on their packaging.
This occurs because CBD is metabolized by the same enzyme as those drugs, and that enzyme is called CYP3A4.
If a user consumes two (or more) substances at the same time that are metabolized by the same enzyme, the enzyme can have a hard time metabolizing all those substances at once.
Elevated levels of an unmetabolized drug in the body are potentially hazardous, and should definitely be avoided.
I use cannabis oil. Cannabis oil helps me a lot. I would actually really like to try some other cannabis products. And I use oil when adding food. Of course, the effect is not the same as from a direct hit on the tongue, but it also turns out very well, in fact. Some pain relieves well.
Thank you for an interesting piece, Marco Medic.
The information below is for palmetto rehab. And for anybody else who is able to take away anything from it. A bit winded, but once I got going, the information just flowed out. If anybody gets any take-away info, then that Rocks! The big one is how to make
Cannabis Topical Cream.
I have both neuropathic and nociceptive pain, in multiple areas. Mainly from injured joints, shoulders, R ankle, most of my neck, and parts of my spine.
I vape cartridges for convenience and when I am where I don’t want to attract attention; such as public events & non-smoking areas. I’m inhaling vapor at a temperature too low to burn. It is discrete and usually does not smell like marijuana. I have vaped at a sports event, with all the lights on. I blew it out down in front of me, or I blow it into my clothes. Vapor dissipates quickly and does not drift slowly up like smoke would.
Every day at home I smoke flower from a water pipe. This is what helps everything overall. I am lucky that I can smoke outside my home. Bubblers work well for me and the water is an excellent filter.
But my Number One relief is from topical CBD/THC Cream. Cannabis Cream. Mixed at a Ratio of 1:1, one to one, even parts of each. It relieves my pain quickly. If one is generous and increases the amount used, relief from pain may last 2 to 3 hours.
Even in ratios of 1 to 1, the THC doesn’t have an effect on me. One would have to use a very expensive amount of cream for it to register beyond trace amounts in urinalysis.
There is a symbiosis between CBD & THC. The THC reinforces the CDB, and the CBD ameliorates, or lessens the mind effects from the THC. The effects though, are present mainly when ingesting oils, which would have an effect on your mind.
When the Cannabis Cream is not available and I have access to oils, I can make my own in any ratio I would like. Experiment, CBD/THC Ratios of 2:1, 3:1, and the reverse,
1:2, 1:3, may work better for some people.
For me and my pains, we all prefer 1:1.
I would like to mention that this cream also works for my stubborn spasms wherever they occur. Neck, back, lumbar (lower back), and other joints & places.
Back to making my own Cannabis Cream when I have to. I use:
250-300mg of CBD Oil.
250-300mg of THC Oil.
2 ounces (60ml) of Skin Cream.
I Mix it by hand until there is no more visible oil floating on the cream.
I prefer to use Indica derived CBDs (Remedy for ex.) & THC. I don’t care if I have to mix the last bits of oils from any number of leftover jars. It doesn’t matter if I have more of one than the other when it comes time that I’m running out of cream. That causes me a lot of concern, if I were to run out of Cannabis Cream. For me and joint pain, muscle pain, electrical nerve pain, or spasms. My first answer is Topical Cannabis Cream. It acts within minutes.
To hell with, “Be safe”. Hey, have fun! You just have to manage risk.
