Do you want to try CBD patches to help quell pain? Read on to learn whether these products are on par with other CBD formulations to provide pain relief.
How CBD Patches May Help With Pain
The transdermal delivery system is a process that provides drug absorption through the skin. It offers a non-invasive alternative for parenteral (injection) routes, avoiding issues like needle phobia(1).
Public and medical interest in CBD (cannabidiol) have been rising(2). Hence, CBD is now available in various formats, allowing individuals to tailor their method of use to their needs.
For instance, transdermal CBD patches are a discreet option for people who do not like inhaling or ingesting CBD. However, studies regarding the efficacy of CBD patches, particularly on pain, are limited.
Still, CBD’s purported medical benefits and activity in the ECS (endocannabinoid system) may elucidate how CBD patches may help with pain.
CBD and the Endocannabinoid System
Cannabidiol, popularly known as CBD, is an active constituent of cannabis. Despite CBD being an essential substance of medical marijuana, the compound is mainly derived from hemp plants.
Meanwhile, the endocannabinoid system is responsible for maintaining bodily balance or homeostasis. It is composed of enzymes, endocannabinoids, and cannabinoid receptors (CB1 and CB2) present throughout the brain and body.
CBD and THC (tetrahydrocannabinol), the primary psychoactive compound of the cannabis plant, may interact with the cannabinoid receptors(3).
CB1 receptors are found within the pain pathways of the CNE (central nervous system) and may affect CBD-induced analgesia (loss of pain perception)(4).
Meanwhile, CB2 receptors, which are mainly present in immune cells, may affect CBD-induced anti-inflammatory properties(5).
Transdermal CBD Patches
CBD transdermal patches are infused with cannabidiol.
Transdermal products like CBD patches and nicotine patches (medicines used to quit smoking) are absorbed through the skin’s layers and into the bloodstream.
In 2003, formulations containing cannabidiol were studied to determine the compound’s efficacy in reducing pain when conventional treatment options have failed(6).
For instance, emerging data suggests a promising effect of cannabis and CBD in fibromyalgia, a condition characterized by fatigue, depressive episodes, and chronic pain(7).
The Benefits of Using CBD Patches for Pain
Studies regarding CBD patches for pain are still in their infancy.
However, animal research from the European Journal of Pain suggested that transdermal CBD may reduce inflammation and arthritis pain-related behaviors without detrimental side effects(8).
The researchers administered 0.6, 3.1, and 6.2mg of CBD gels daily for four consecutive days to a rat model following arthritis induction.
Their findings showed that 6.2mg per day may be an effective dose of CBD in gel format(9).
Meanwhile, an animal study using a murine model reported that the transdermal application of ethosomal CBD resulted in steady CBD plasma levels for 72 hours and prevented inflammation and edema (swelling)(10).
Ethosomal systems refer to novel vesicular carriers with a high percentage of ethanol. These nanocarriers are designed to enhance the transdermal delivery of substances(11).
A 2020 study from Pharmaceuticals provided a systematic collection of data on CBD’s skin permeation(12).
The researchers observed that hydrophilic gel containing propylene glycol (79%, weight for weight) may be optimal for topical CBD administration(13).
Lipophilic ointment and paraffin oil may also be suitable preparations for CBD administration, promising a significant permeation performance(14).
In terms of skin retention, the transdermal patch may also provide comparable results(15).
Although the findings seem promising, they are inconclusive and mostly done on animal models. In addition, most of the studies did not focus on CBD patches.
However, researchers who want to explore the benefits of using CBD patches for pain may find these results helpful.
How to Use a CBD Patch
Unlike topicals, transdermal patches like CBD patches have a systemic effect because they can penetrate all seven epidermal layers of skin and reach the bloodstream(16).
Below are the steps on how to use a CBD patch:
- Read the package instructions and follow them accordingly before using a CBD patch.
- Choose a skin area where you will apply the patch. The area should be clean and free of oils, lotions, or powders.
- Open the packaging carefully. If you are using scissors or cutters, make sure not to cut the patch.
- Remove the protective liner from the patch without touching the sticky side.
- Check if the patch is flat against the skin once you apply it. There must be no folds or bumps in the patch.
- Use your fingers to peel the CBD patch off slowly, then dispose of it properly.
How Long Do CBD Patches Take to Help With Pain?
The onset time of cannabidiol in CBD patches is between 15 and 30 minutes. Generally, you will feel the effect of CBD via this particular transdermal method for up to 8 hours(17).
How Long Will CBD Patches Help With Pain?
How long cannabidiol in CBD patches lasts after it takes effect depends on its pharmacokinetics.
Pharmacokinetics is the movement of a substance or drug into, through, and out of the body. It includes the time course of drug absorption, distribution, metabolism, excretion, and bioavailability.
Bioavailability is the extent to which a particular substance becomes entirely available to its intended biological destinations.
The bioavailability of CBD via the transdermal route is 90%(18).
How to Shop for CBD Patches for Pain
CBD brands like Mary’s Nutritionals, Hemp Bombs, and Pure Ratios are dedicated to giving their customers high-quality CBD products, including transdermal CBD patches for pain.
Generally, there are two designs of transdermal patches currently available: the matrix and the reservoir type.
The matrix patch incorporates the substance into an adhesive polymer matrix, from which the active ingredient is continuously released into the skin(19).
Meanwhile, reservoir patches hold a drug in a solution or gel. Although these patches give tighter control of delivery rates, they may cause an initial burst of drug release(20).
On the contrary, the active ingredients are evenly distributed throughout the matrix patch. Hence, these patches may carry less risk of accidental overdose and offer less potential for abuse(21).
Still, when shopping for CBD patches, the best one is what works for you.
It is also worth noting that some CBD patches may contain ingredients such as aloe vera, menthol, and lidocaine.
Lidocaine helps relieve nerve pain after shingles, a viral infection that triggers a painful rash.
Lidocaine and the other ingredients mentioned may provide added benefits.
For instance, aloe vera may help retain skin moisture(22).
Meanwhile, menthol has anti-inflammatory potential and may accelerate wound healing(23). However, some individuals have contact sensitivity to menthol(24).
Still, it is essential to talk with a doctor versed in cannabis use before buying CBD patches. These experts can advise you regarding possible allergic reactions or recommend hypoallergenic, water-resistant, and long-lasting CBD patches.
Aside from CBD patches, other CBD formats available in the market include CBD oil, tinctures, vapes, CBD topicals like lotions and creams, and CBD edibles like gummies.
Before shopping for CBD patches or other CBD products for overall wellness, here are some more pertinent factors to consider:
1. Hemp Extracts
A full-spectrum CBD product has all compounds of the cannabis plant, including CBD and other cannabinoids, essential oils, flavonoids, and terpenes.
Terpenes are the chemical components of essential oils responsible for the aroma of cannabis(25).
Meanwhile, flavonoids are active compounds in cannabis that have purported antioxidant, anti-inflammatory, and antiviral actions(26).
Full-spectrum CBD oil also has 0.3% THC. Additionally, it is known to produce the entourage effect.
The entourage effect is a theory stating that the biologically active compounds of cannabis work better when administered together.
Frontiers in Plant Science study suggested that due to the entourage effect, full-spectrum hemp extracts may produce better therapeutic benefits than pure CBD(27).
CBD isolates are made of pure CBD. On the other hand, broad-spectrum CBD oil also contains all of the natural compounds of cannabis. However, this CBD variant is usually THC-free.
2. Ingredients
If possible, always opt for CBD products, like transdermal CBD patches, made from U.S.-grown hemp. Legitimate producers grow hemp in accordance with the tribal plans and the regulations of the United States Department of Agriculture (USDA).
3. Extraction Method
The extraction method is the process where CBD oil is derived from cannabis.
Carbon dioxide, ethanol, or solvent extraction is preferred to create a safe CBD product(28). On the other hand, extraction techniques utilizing hexane or butane may leave harmful residues, like heavy metals, pesticides, and other contaminants.
4. Carrier Oils
The most commonly utilized carrier oils are MCT oil (medium-chain triglyceride oil), coconut oil, and hempseed oil.
What to Avoid When Shopping for Transdermal CBD Patches for Pain
The FDA (Food and Drug Administration) does not endorse CBD pain patches. Hence, the agency does not have regulatory guidelines overseeing such products’ testing, marketing, and labeling.
For this reason, consumers should be extra careful when buying transdermal CBD patches.
Make sure to avoid brands that do not provide lab reports or COAs (certificates of analysis) that come from a trusted third-party lab.
Even if the company you choose has readily accessible COAs from its website, always check if the CBD product label matches the information provided on the site.
A research article published on January 5, 2022, stated that some commercial CBD products contain percentages of CBD that vary significantly from the information provided on their labels(29).
Meanwhile, since most people have different opinions and experiences of a product, understanding the overall impression given by other customers will help you with your decision-making.
Therefore, read customer feedback to get more insight into the CBD brand and its products.
If a specific brand gets negative feedback, make sure to research more about the issue before deciding not to purchase from the company altogether.
An article from Harvard Business Review stated that a firm that provides a tailored solution to a particular complaint shows other reviewers that it cares about customer issues(30).
Risks and Side Effects of Using CBD Patches for Pain
CBD is relatively safe for use(31). Nonetheless, the FDA believes that additional work is warranted to build an extensive research database on CBD usage and safety(32).
Moreover, the agency warns the public regarding the possible side effects people may encounter when using CBD. These side effects include(33):
- Changes in alertness
- Gastrointestinal distress
- Changes in mood
Legality of CBD
The 2018 Farm Bill states that Cannabis sativa L. and other derivatives of cannabis with less than 0.3% THC content on a dry weight basis are deemed legal under federal law(34).
