Cannabis has been used for centuries for medicinal purposes and contains compounds called cannabinoids that may offer potential health benefits. Medical cannabis is now legalized in many countries and states for treating chronic pain, with growing evidence supporting its use in this area.

Medical cannabis, also known as medical marijuana, refers to the use of the cannabis plant or its compounds, such as cannabinoids, for therapeutic purposes. While cannabis has a long history of use for potential pain relief, it is only recently that medical science has begun to fully understand its potential.
This article explores the benefits of using medical cannabis for pain relief, the types of pain it may help with, and how it can be used as a treatment option. We also take a closer look at how cannabis compares to traditional opioid-based medications for managing chronic or acute pain.

Medical cannabis describes the use of cannabis specifically for medical purposes, including using various plant compounds like CBD and THC to address symptoms related to certain conditions.
Research has shown that medical cannabis may effectively reduce pain intensity and improve patients' quality of life (1).
Medical cannabis works by interacting with our endocannabinoid system, which plays an essential role in regulating various physiological processes within the body (2).
By activating specific receptors within this system, cannabinoids like CBD and THC may help reduce inflammation (3), relieve pain (1), and improve mood (4).
While further research is needed to fully understand how medical cannabis works on a molecular level, strong evidence suggests its potential therapeutic benefits for those struggling with chronic pain.

Medical cannabis works by interacting with the body’s endocannabinoid system, which plays a role in regulating various physiological processes such as pain perception, inflammation, and mood (2). Cannabinoids in medical cannabis bind to CB1 and CB2 receptors within this system, potentially helping to reduce pain and inflammation.

Medical cannabis is available in various forms, each with unique benefits and effects. The most common form is dried flower, which can be vaporized for immediate pain relief. Cannabis oil is another popular form, which can be taken orally or applied topically to relieve pain and inflammation.
For those who prefer not to inhale vapor, capsules containing cannabis extracts are also available. These provide a consistent dose of active ingredients without the need for an inhalation device. Various forms of medical cannabis have proven effective in treating chronic pain associated with conditions such as multiple sclerosis (6) and cancer-related nausea (7).

Research on medical cannabis has shown promising results in alleviating chronic pain, including migraines, neuropathic pain, cancer-related pain, and pain associated with conditions like multiple sclerosis. Cannabinoids such as THC and CBD interact with the body's endocannabinoid system, which plays a role in pain regulation (8).

Neuropathic pain is caused by damage to the nervous system and can be challenging to treat with conventional medications. Medical cannabis contains compounds that interact with the body’s endocannabinoid system, which helps regulate pain perception. Migraines are another form of chronic pain that may respond well to medical cannabis treatment.

Arthritis is a common condition that causes joint inflammation and can lead to chronic pain. Medical cannabis has demonstrated anti-inflammatory properties, which may help reduce swelling and alleviate arthritis-related discomfort. Additionally, some medical cannabis strains contain high levels of cannabidiol (CBD), a non-psychoactive compound that has been studied for its potential as a pain reliever.
Overall, medical cannabis offers promising benefits for treating various types of chronic pain conditions, such as neuropathic pain, migraines, and arthritis, through its interaction with the body's endocannabinoid system or its anti-inflammatory effects due to CBD content.

Research has shown that cannabis can provide pain relief in cases where traditional medications have failed. Several clinical studies have explored the effectiveness of cannabis in managing chronic neuropathic pain, cancer-related pain, and other conditions that cause significant discomfort.
A meta-analysis published in the Journal of the American Medical Association found that patients using medical marijuana experienced significantly greater relief from chronic neuropathic pain compared to those who received a placebo (9).

Cannabis has been investigated as a potential treatment option for various types of pain, including, but not limited to, headaches, spasticity associated with multiple sclerosis, arthritis-related inflammation and joint issues, and fibromyalgia-related discomfort. While research is ongoing to determine its long-term and short-term effectiveness for various pain types, early results are promising.

Some studies suggest that marijuana may yield similar results to conventional opioids or NSAIDs (nonsteroidal anti-inflammatory drugs) without the risks associated with opioid overdose fatalities or gastrointestinal complications common with prolonged NSAID use (10).

The endocannabinoid system (ECS) plays a crucial role in pain management. By binding to cannabinoid receptors, both endocannabinoids and phytocannabinoids can block the release of pro-inflammatory substances, potentially reducing pain and inflammation.

Treating chronic pain with cannabis may provide an effective alternative to traditional pain management methods. Studies have shown that cannabinoids in cannabis can reduce inflammation and relieve chronic pain caused by conditions such as arthritis, neuropathy, and fibromyalgia.
It is important to note, however, that the effectiveness of cannabis for pain relief in chronic conditions can vary from person to person (12).

For effective use of cannabis in treating chronic pain, dosage and method of consumption play a critical role. It is recommended to start with low doses and gradually increase until the desired effect is achieved. Methods of consumption include vaporizing, edibles, tinctures, or applying creams or patches directly to the painful area. Additionally, consulting a doctor or medical professional is advised if considering medical cannabis for chronic pain treatment.

Cannabis is known to relieve nerve pain by interacting with the body’s endocannabinoid system, which plays an essential role in regulating pain perception, inflammation, and immune function.
Cannabinoids in cannabis bind to the receptors within this system, reducing pain signal transmission and promoting relaxation. When choosing a strain for treating nerve pain, different strains vary in effectiveness. Indica strains are often preferred for their high levels of relaxing terpenes and cannabinoids like CBD, which reduce inflammation without producing psychoactive effects.
While sativa strains may be less effective in alleviating chronic pain, they offer other benefits, such as mood enhancement or increased energy, so there is no single approach to determining what works best.

Cannabinoids in cannabis oil are potentially effective for relieving back pain (13). CBD and THC are the two primary compounds that interact with the body’s endocannabinoid system (2), which plays a crucial role in regulating pain perception. When consumed, these cannabinoids help reduce inflammation and pain signals throughout the body.
There are various ways to use CBD oils for acute or chronic back pain: oral ingestion, topical application on the affected area, and sublingual administration. Each method has its pros and cons, depending on personal preferences and specific symptoms.

When it comes to relieving inflammation caused by arthritis, THC and CBD work effectively together (14). Both cannabinoids have been found to possess anti-inflammatory properties that may help alleviate pain for arthritis patients. Using extracts containing both THC and CBD provides several benefits, including longer-lasting effects compared to vaporizing.
In addition to consuming edibles, there are various methods for administering medical cannabis, such as vaporizing or ingesting. Smoking is the fastest way to feel the effects, though it may not be suitable for individuals with respiratory issues. Vaporizing offers a less harmful alternative to smoking, while consuming capsules or edibles provides a more discreet option for use.

The use of cannabis for pain management in older adults has gained attention as a potential alternative treatment option. Research suggests that medical cannabis can effectively relieve chronic pain, including arthritis and nerve pain, which are common among older adults (15).
Healthcare professionals advise that cannabis use for pain should be closely monitored and administered under medical supervision. However, as more research is conducted on the benefits of medical cannabis, it could become a viable option for managing chronic pain in older adults.

Menstrual pain is a common issue faced by many women each month. Due to its anti-inflammatory and analgesic properties, cannabis may be effective in relieving menstrual discomfort. Here are some ways cannabis may help with menstrual pain (16):

It’s essential to note that different types of cannabis and methods of consumption exist. Consulting a doctor is recommended before trying new treatments for menstrual pain.

Medical cannabis has shown promise as an effective treatment for chronic pain. Research suggests that cannabinoids, the active compounds in cannabis, may help relieve inflammation and nerve pain by interacting with the body’s endocannabinoid system (17). However, it’s important to note that the correct dosage is essential to achieve the desired pain-relieving effect.
While medical cannabis offers several benefits for individuals with chronic pain, potential side effects should also be considered. These may include dizziness, dry mouth and eyes, increased heart rate, and anxiety. It is crucial to discuss any concerns about using medical cannabis with a doctor before starting treatment.
Different forms of medical cannabis, such as oils, capsules, and edibles, can have varying effects on the body. Consulting a doctor can help determine which form is best suited to your individual needs. Additionally, finding the correct dosage is critical for effective pain relief without unwanted side effects.
Factors affecting dosage may include age, weight, metabolism, and the severity of the pain. Starting with a low dose and gradually increasing it under medical supervision can help find the optimal dosage.

For those suffering from chronic pain, medical cannabis can be a viable option to alleviate symptoms. However, how quickly cannabis relieves pain can depend on several factors.
First, it’s important to recognize that cannabis primarily contains two cannabinoids: THC (tetrahydrocannabinol) and CBD (cannabidiol), both of which have been attributed with pain-relieving properties. THC is known for its psychoactive effects, whereas CBD is not. Therefore, the THC and CBD content of your cannabis product may influence the speed of pain relief.
Additionally, the method of consumption can also play a role. Vaporizing cannabis can provide rapid relief, typically within minutes, although the effects may only last a few hours. Edibles, on the other hand, may take longer to take effect—usually between 30 minutes and an hour—but their effects can last for several hours.
Another critical factor is an individual’s tolerance and sensitivity to cannabis. Those who use cannabis regularly may experience faster pain relief, while newcomers to cannabis might take longer to feel its effects.

The short answer is that it depends on the specific medications and the individual’s medical situation.
Cannabis can potentially interact with other medications in ways that may be harmful. For example, cannabis may enhance the effects of sedatives like benzodiazepines and opioids, which can lead to increased dizziness and confusion. It may also interact with blood thinners like warfarin, increasing the risk of bleeding.
Your doctor can assess the potential risks and benefits and determine if cannabis is a safe and effective option for you.
It’s also important to note that there are various types of cannabis products, including those with THC (the psychoactive compound) and those without. Depending on the individual’s condition and symptoms, doctors may recommend different types of cannabis products.

The legal status of medical cannabis varies significantly between countries and states. In some regions, such as Germany and the United Kingdom, medical cannabis is legal with a doctor’s prescription, while in other areas, it remains illegal or decriminalized with no access to legal medical use. Legal requirements for using medical cannabis also vary by location.
Common requirements for the legal use or prescription of medical cannabis typically include:

When considering medical cannabis for pain management, it is essential to be aware of potential side effects. Common side effects include dizziness, dry mouth and eyes, fatigue, and changes in appetite. However, these symptoms are generally mild and short-lived.
Interactions with other medications are another factor to consider when using medical cannabis. Cannabis can interact with certain prescription medications, such as sedatives or antidepressants, leading to enhanced effects or unexpected side effects.
Patients should always consult their doctor before incorporating medical cannabis into their treatment plan.

When it comes to pain relief, cannabis is a potentially promising alternative to opioids. Studies have shown that cannabinoids in cannabis can effectively relieve chronic pain and inflammation without the risks of addiction or overdose associated with opioid use (10).

Research studies have shown promising results for medical cannabis as an option for pain relief. Studies suggest that it may help alleviate chronic pain related to conditions such as multiple sclerosis and arthritis. Medical cannabis has also been effective in reducing the need for opioid medications, which carry a high risk of addiction and overdose.


The legal status and availability of medical cannabis vary widely across countries. While some regions have legalized its use, others allow it only under specific conditions or not at all. However, there is growing global support for the legalization of medical cannabis due to its potential therapeutic benefits.

As research into the medical properties of cannabis continues to progress, future studies will likely focus on the effectiveness of different strains and dosages for various types of pain relief. Additionally, further investigation is expected on how cannabinoids interact with other medications to ensure safe use for patients who take multiple medications simultaneously.

With more data emerging from studies on medical cannabis for pain relief, the expansion beyond traditional pharmaceuticals toward natural alternatives, such as these cannabinoid products, is likely to continue.
