CBD Patches: What Are They and How Do They Work?

CBD patches are a relatively new way of using cannabidiol (CBD), a compound derived from the cannabis plant that has many potential health benefits. CBD patches are similar to nicotine or birth control patches, but instead of delivering nicotine or hormones, they deliver CBD through the skin and into the bloodstream. CBD patches are designed to provide localized and long-lasting relief for various conditions, such as pain, inflammation, anxiety, and insomnia. But how do CBD patches work, and what are their advantages and disadvantages? In this article, we will answer these questions and more.

How Do CBD Patches Work?

CBD patches are transdermal patches, which means they deliver substances through the skin and into the bloodstream. The skin is a semi-permeable membrane that allows some molecules to pass through, but not others. CBD patches contain a layer of CBD-infused gel, oil, or solution that is applied to the skin. The CBD molecules then diffuse from the patch into the skin, where they encounter capillaries (small blood vessels) that carry them to the rest of the body.

CBD patches work by bypassing the digestive system and the liver, which are involved in oral CBD consumption. When you take CBD orally, such as in oil or gummy form, it has to go through the digestive tract and be metabolized by the liver before it reaches the bloodstream. This process reduces the amount and the bioavailability (the rate and extent of absorption) of CBD that reaches your system. CBD patches avoid this first-pass metabolism and deliver more CBD directly to your bloodstream.

CBD patches also offer a more consistent and sustained release of CBD than other topical methods, such as creams or oils. Topical creams are absorbed by the skin quickly, but their effects wear off after a few hours. You would need to reapply them frequently to maintain a steady level of CBD in your system. CBD patches, on the other hand, can last for several days (depending on the brand and dosage) and provide a steady stream of CBD to your target area.

What Are the Benefits of CBD Patches?

CBD patches have many potential benefits for various conditions, especially those that involve pain and inflammation. CBD is known to have anti-inflammatory, analgesic (pain-relieving), anti-anxiety, anti-insomnia, and neuroprotective properties. Some of the conditions that CBD patches may help with include:

  • Arthritis: Arthritis is a common condition that causes joint pain, stiffness, swelling, and reduced mobility. CBD patches may help reduce inflammation and pain in arthritic joints by interacting with the endocannabinoid system (ECS), a biological system that regulates various functions in the body, including pain perception, inflammation, immune response, mood, sleep, and memory. The ECS consists of endocannabinoids (cannabinoids produced by the body), cannabinoid receptors (CB1 and CB2), and enzymes that break down endocannabinoids. CBD may enhance the activity of the ECS by preventing the breakdown of endocannabinoids or by binding to other receptors that modulate pain and inflammation.
  • Back pain: Back pain is another common condition that affects millions of people worldwide. It can be caused by various factors, such as injury, muscle strain, spinal disc problems, posture issues, or chronic conditions like sciatica or fibromyalgia. CBD patches may help alleviate back pain by reducing inflammation, relaxing muscles, improving blood flow, and modulating pain signals in the brain and spinal cord.
  • Nerve pain: Nerve pain or neuropathy is a type of pain that results from damage or dysfunction of the nerves. It can be caused by various conditions, such as diabetes, shingles, multiple sclerosis (MS), chemotherapy, or injury. Nerve pain can manifest as burning, tingling, numbness, or shooting sensations in different parts of the body. CBD patches may help ease nerve pain by reducing inflammation, protecting nerve cells from oxidative stress or degeneration, and influencing neurotransmitters (chemical messengers) that regulate pain sensation.
  • Anxiety: Anxiety is a mental health disorder that affects millions of people worldwide. It can cause symptoms such as nervousness, fear, worry, panic attacks, racing heartbeats, sweating, trembling, or difficulty breathing. CBD patches may help reduce anxiety by interacting with serotonin receptors (5-HT1A), which are involved in mood regulation, stress response, and emotional processing. CBD may also modulate the activity of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits nerve impulses and has a calming effect on the brain.
  • Insomnia: Insomnia is a sleep disorder that affects millions of people worldwide. It can cause difficulty falling asleep, staying asleep, or waking up too early. It can also affect the quality and quantity of sleep, leading to daytime fatigue, impaired concentration, mood swings, or health problems. CBD patches may help improve sleep quality and duration by reducing anxiety, pain, or inflammation that may interfere with sleep. CBD may also regulate the circadian rhythm (the body’s natural sleep-wake cycle) by influencing melatonin production, a hormone that controls sleep onset and duration.

What Are the Disadvantages of CBD Patches?

CBD patches are generally considered safe and well-tolerated, but they may have some disadvantages or side effects for some people. Some of the possible drawbacks of CBD patches include:

  • Skin irritation: Some people may experience skin irritation, redness, itching, or rash at the site of application. This may be due to the adhesive used in the patch or the other ingredients added to enhance CBD absorption. People with sensitive skin or allergies should test a small area of skin before applying a CBD patch and discontinue use if they notice any adverse reactions.
  • Drug interactions: CBD may interact with some medications, especially those that are metabolized by the liver or have a narrow therapeutic window (the range between an effective dose and a toxic dose). CBD may inhibit or induce certain enzymes (such as cytochrome P450) that are responsible for breaking down drugs, resulting in increased or decreased drug levels in the blood. This may affect the efficacy or safety of the drugs. Some examples of drugs that may interact with CBD include blood thinners, antidepressants, anticonvulsants, opioids, and acetaminophen. People who are taking any medications should consult their doctor before using CBD patches and monitor their drug levels and effects.
  • Legal status: CBD patches are legal in most states in the U.S., as long as they are derived from hemp and contain less than 0.3% THC (the psychoactive component of cannabis). However, some states may have different laws or regulations regarding CBD products, so it is advisable to check the legal status of CBD patches in your state before purchasing or using them. You should also be aware that CBD patches may show up on drug tests, depending on the amount and type of CBD and THC in the patch and the sensitivity and accuracy of the test.

How to Use CBD Patches?

CBD patches are easy to use, but there are some tips and precautions to follow to ensure optimal results. Here are some steps to use CBD patches:

  • Choose a clean, dry, and hairless area of skin to apply the patch. Avoid areas with wounds, cuts, burns, or irritations. You can choose an area close to your pain site or a venous area (such as the inner wrist, ankle, or behind the ear) for faster absorption.
  • Remove the protective liner from the patch and press it firmly onto your skin. Make sure there are no air bubbles or wrinkles on the patch. You can use a bandage or tape to secure the patch if needed.
  • Wash your hands after applying the patch and avoid touching your eyes, mouth, or nose.
  • Leave the patch on for as long as directed by the manufacturer or your doctor. Most CBD patches last for 24 to 96 hours, depending on the brand and dosage. Do not reapply a patch to the same area for at least a week to avoid skin irritation.
  • Remove the patch gently and dispose of it safely. Do not flush it down the toilet or throw it in the trash where children or pets can access it.
  • Wash the area where you applied the patch with soap and water and pat it dry.


CBD patches are a convenient and effective way of using CBD for various conditions, especially those that involve pain and inflammation. CBD patches deliver CBD through the skin and into the bloodstream, bypassing the digestive system and providing consistent and long-lasting relief. CBD patches have many potential benefits for conditions such as arthritis, back pain, nerve pain, anxiety, and insomnia. However, they may also have some disadvantages or side effects for some people, such as skin irritation, drug interactions, or legal issues. Therefore, it is important to consult your doctor before using CBD patches and follow the instructions carefully.
