CBD vs THC For Chronic Pain: Comparing Two Potent Cannabinoids
Are you trying to decide between CBD and THC for relieving chronic pain?
Maybe you’re just curious about the differences between the two. It’s easy to assume that these two compounds are similar, since they both come from the same plant. But while they can both play an important role in managing chronic pain, CBD and THC are very different substances, and each one works differently in the body.
In this article, we’ll explore how these two popular cannabis compounds work to relieve chronic pain — both separately and together.
The Basics of THC and CBD
CBD (short for cannabidiol) and THC (tetrahydrocannabinol) belong to a group known as cannabinoids, and they are derived from the cannabis plant – either hemp or psychoactive cannabis (“marijuana”). There are over 100 different cannabinoids, but CBD and THC are the most dominant substances in cannabis, making them responsible for most of the effects that marijuana is famous for.
Both CBD and THC work by interacting with the endocannabinoid system, which refers to a group of receptors in the body that regulate various physiological processes, including pain, digestion, mood, and sleep. Cannabis is well-known for its versatility, helping people worldwide with problems like insomnia, PTSD, and pain – and it’s all because these endocannabinoid receptors are involved in so many different bodily functions.
By far, the most notable difference between CBD and THC is that THC causes a high, while CBD does not. CBD’s lack of psychoactive effects is one of the reasons it has become so popular as of late. In fact, CBD can counteract some of THC’s psychoactive effects (like euphoria and anxiety). This is why high-CBD strains of cannabis are often popular for pain relief, since they allow one to keep a clear head.
THC is also associated with more side effects than CBD, although these tend to be mild and are temporary. Some well-documented side effects of THC are dry mouth, red eyes, and hunger. Most people who use CBD report little to no side effects, with sleepiness being the most common, especially at high doses.
CBD Benefits for Chronic Pain and Inflammation
Research has established that CBD is an effective anti-inflammatory, with strong evidence that it can relieve pain from inflammatory conditions such as arthritis. For example, a 2017 study concluded that CBD can reduce osteoarthritis-related pain and inflammation, and prevent nerve damage.
Other studies support CBD for relief of neuropathic pain and incision-related pain. CBD’s effectiveness at relieving different types of pain has led to its popularity among people with conditions such as fibromyalgia, IBS, multiple sclerosis, and cancer.
THC Benefits for Chronic Pain and Inflammation
Although there is plenty of research supporting the use of cannabis for pain relief in conditions like Crohn’s disease, chronic migraine, and fibromyalgia, less attention has been paid to the specific benefits of THC. The few studies that are available tend to be small and show conflicting results.
A recent study in Neurology found THC is effective for alleviating chronic nerve pain. A larger study, involving 177 cancer patients, found that while THC was not effective at reducing pain, the patients who took a CBD/THC combination had their pain reduce by over 30 percent when compared to placebo. Another double-blind study supported this conclusion when using THC for post-surgery pain. Meanwhile, a 2017 study found both THC and CBD, when taken alone, were effective for reducing chemotherapy-related pain in mice.
The same study also discovered that when combined, previously ineffective doses of CBD and THC could relieve pain. This relates to an important benefit of THC – it can enhance the pain-relieving properties of CBD through what’s known as the entourage effect.
How CBD and THC Work Together: The Entourage Effect
Although CBD and THC are the most dominant compounds in the cannabis plant, they aren’t alone. There are dozens of other cannabinoids and terpenes that work together to provide different synergic effects. For example, the third most dominant compound in cannabis, cannabichromene (CBC) has shown anti-inflammatory benefits similar to those of CBD.
The entourage effect refers to the benefits that one can experience by ingesting multiple cannabinoids together, including CBD and THC. In short, while CBD and THC have their own powerful benefits, they tend to be more potent when combined – especially when it comes to pain relief. An analysis of 18 studies on cannabinoids for multiple sclerosis pain found that the combination of THC and CBD was slightly more effective for pain reduction than CBD on its own.
The entourage effect is why CBD products fall into two categories: full spectrum and isolate. Full spectrum CBD products contain all the cannabinoids and terpenes that were extracted along with CBD. On the other hand, isolate CBD products remove all traces of these other substances, resulting in a product that is pure CBD.
Some people have better success using full spectrum CBD products for pain relief because of the entourage effect. However, due to the variety of cannabinoids and terpenes, full spectrum products can be somewhat unpredictable in their effects. Isolate CBD products are often favored by those who can’t tolerate any traces of THC, or need to avoid it due to drug testing.
Legalities and Limits of THC In CBD Products
The majority of CBD products you’ll find on the market today are made from hemp, which by law can contain up to a maximum of 0.3 percent THC. This means hemp-derived, full spectrum CBD products are likely to contain low amounts of THC. There are CBD products available that are made from marijuana instead of hemp, and therefore contain a higher percentage of THC. For legal reasons, these products tend to be restricted to dispensaries.
Closing Thoughts on CBD vs. THC
As you can see, there isn’t a simple answer for whether CBD or THC is better for chronic pain. Both compounds bring their own benefits to the table, and in regard to chronic pain, there is evidence that they’re more effective when taken together due to the entourage effect.
Either way, it’s clear that cannabis has plenty to offer for chronic pain patients, and cannabis products can vary widely in effectiveness. So if you don’t have success with one product, don’t give up; try something new, whether it’s a different blend of cannabinoids, or a different potency.
