CBD Oil Before Surgery: Is it safe? 5 minute breakdown (2021)
January 03, 2021 6 min read
Is taking CBD oil before surgery a good idea? In this article, we outline what many surgery patients who use CBD want to know.
Even though the World Health Organization seems to support the widely accepted, positive safety status of cannabidiol, users of CBD products should still practice caution when using new wellness supplements, especially alongside other medications or treatments.
Because of the way that CBD interacts with some medications, it’s crucial that users take the time to look into how CBD products can affect other aspects of your wellness routine or required medical treatments. One of the most important considerations is the use of CBD oil before surgery.
If you’re wondering “Should I stop taking CBD oil before surgery?” you’re in the right place. Let’s take a look at what the research says, as well as some expert opinions, on how CBD may affect your pre-surgical routine.
CAN I TAKE CBD OIL BEFORE SURGERY?
Various studies have verified that CBD is safe, and CBD’s safety profile is generally well-rounded. Still, researchers are aware that cannabidiol interacts with multiple medications, which may complicate things when surgical anesthesia or other necessary medications become part of the picture.
So, can you take CBD before surgery?
Here’s what we know:
Many sources suggest that you shouldn’t take much of anything, including water, before surgery to prevent serious complications, like aspiration, increased risk of infection, increased heart rate, or sudden nausea and vomiting.
When you go in for a surgical procedure, you’ll often fill out a form or be verbally assessed regarding your use of opioids or other medications. That’s because certain medications can affect the anesthesia, in some cases making it totally ineffective.
Alternatively, frequent use of some medications may not render the anesthesia completely useless, but your anesthesiologist should know so that he or she can adjust your dose based on your tolerance.
Many sources suggest that CBD falls into line with these ideas. Dr. Perry Solomon, MD, suggests that CBD oil is safe to take in the days prior to scheduled surgery under certain conditions.
For instance, research shows that CBD may also have anti-coagulant effects, meaning it may do the same job as traditional blood thinners. According to Dr. Solomon, CBD may be okay to take before surgery as long as you aren’t taking other medications that may interact with CBD, like blood thinners.
However, Dr. Solomon also says that you should “observe the instructions by whoever calls you from the hospital regarding what time to stop eating and drinking fluids,” making sure you don’t take CBD after that time either.
In short, CBD may be safe to use up until you should discontinue other medications, food, and beverages. This is true for edible CBD items, like CBD Gummies, and other types of CBD products, like oils, capsules, or vaporizers.
Just like with opioid medications, you should inform your doctor and your anesthesiologist about your CBD use.
According to Dr. David Hepner, MD, MPH, this communication is crucial. He states in a Harvard Health publication that traditional cannabis use can alter the amount of anesthesia mediations needed during surgery by more than 300%.
Even though CBD alone may not cause the same resistance to anesthesia as THC, you still want your anesthesiologist to be prepared to increase your dose if needed. That means you should keep track of exactly how much CBD oil you take and when you take it so that you can give accurate information to the doctor.
Many people are interested in using CBD to manage anxiety prior to the surgery, but most research suggests that taking CBD too close to your surgery could pose risks, especially since many doctors don’t quite understand the full effects of CBD oil yet.
Of course, using CBD after surgery may be a different story, and may actually pose an even greater range of benefits than as a pre-operative supplement.
BENEFITS OF CBD OIL FOR POST-OPERATIVE RECOVERY
So what about taking CBD oil aftersurgery? After most surgical procedures, your doctor will send you home with some sort of prescription to help aid the recovery process and manage pain in the days after your surgery.
According to Dr. Solomon, CBD may help the recovery process as well. He suggests that a 1:1 CBD:THC tincture may even be an appropriate replacement for opioids to manage post-recovery pain.
CBD also has benefits when used on its own, and according to Dr. Solomon, “as an anti-inflammatory, it may even help with your wound healing.”
Research about the cannabinoid is limited. However, there is some evidence that suggests cannabidiol has many effects that may make it useful for managing post-operative discomfort and aiding recovery.
Like our expert suggested, cannabidiol has been linked to powerful anti-inflammatory effects, which is why many people use it for managing conditions like arthritis. CBD may help inhibit the inflammatory response by binding with certain neuroreceptors to prevent signals of inflammation from reaching the brain.
Research shows that it works in nearly the same way to help prevent pain signals from reaching the brain, too, which means CBD could be useful for managing pain after your surgery.
Different types of cannabidiol applications may help with these symptoms, and CBD topicals may be an effective option for managing postoperative recovery due to the way CBD interacts with the Endocannabinoid System in the skin.
The side effects of surgery vary depending on unique biological characteristics, medications you take, or the type of surgery you had. However, nausea, vomiting, and loss of appetite are common after many surgical procedures, especially in those who suffer from one of many chronic health conditions. Studies show that CBD is an effective treatment for regulating nausea and vomiting.
Fatigue, another common surgery side effect, may be managed with CBD oil, too. Studies show that cannabidiol has wake-promoting effects, and many people take CBD alongside their coffee to help boost their focus during the day.
Experts also suggest that in larger doses, cannabidiol may even work as a sort of sleep aid. Studies show that CBD may be useful for managing insomnia, especially if sleeplessness is caused by anxiety, inflammation, or pain. Alternatively, other cannabinoids (like CBN) have been linked to sleep benefits that may be useful.
Consult your Doctor about using CBD before surgery and/or after surgery. While your doctor may prescribe medication for any of your post-operative symptoms, many people turn to cannabidiol instead because of its low potential risks.
When compared to most prescription medications, especially narcotics like opioid medications, the side effects of CBD are considerably mild and rare.
For most people, CBD provides the right amount of post-operative relief from anxiety, inflammation, pain, and more, without the same adverse side effects of many prescription options.
TALK TO YOUR DOCTOR ABOUT USING CBD OIL BEFORE OR AFTER SURGERY
As you can see, there are several ways that cannabidiol may benefit you in the days before or after your surgery, but most experts would suggest avoiding CBD in the hours before a surgical procedure, the same time your doctor recommends avoiding other medications, beverages, and foods.
If you use CBD regularly, or took any CBD in the days prior to your surgery, be sure to inform your doctor and your anesthesiologist.
If you want to reap the many benefits of CBD after your surgery, there are multiple different ways to consume CBD that may work for you. Just be sure that you always talk about plans to change your wellness routine with your doctor, especially if you are going to use CBD products in place of any prescription medications.

CBD Surgery Facts You Should Not Ignore
Loving your cannabidiol (CBD) especially for its anxiolytic and anti-inflammatory properties? Great. Can you safely take it before surgery to help you through the ordeal? Well, as usual, the answer is not straightforward, and those in the know don’t seem to agree 100 percent, either. But that’s not a problem.
With CBD, hospital stays can definitely be more positive, but you need to see the whole picture before making a choice. Surgery involves a lot more than meets the eye, obviously. So, you and your doctor will need to work together closely if you want to include CBD in your arsenal against anxiety, pain, and inflammation.
CBD Surgery—always Do This First
Let’s lead with one important piece of advice, though: always disclose your CBD and/or cannabis use (including weed) to the surgeon and anesthesiologist or any medical staff responsible for your hospital intake. Also, ask the presiding surgical doctor if you should be ingesting any cannabinoid at all, and take that advice seriously. Read on for the basic guidelines, but sticking to what the doctor says will be the best course of action.
Are there any guidelines as to who should really avoid taking CBD before surgery, though? Yup, and they’re pretty simple—if you are on any anticoagulant, you should completely avoid taking CBD or any cannabis-related product long before getting operated on.
Here’s why, according to Dr. Alaa Abd-Elsayed, writing for ASRA News. Abd-Elsayed is a pain physician and anesthesiologist:
“Blood coagulation studies indicate that . CBD showed mild anticoagulating effects. Furthermore, the authors demonstrated that 50% clotting times in obese and lean rats treated with cannabis extracts were 1.5- to 2.0-fold greater than their controls (rats not treated with cannabis extracts). The authors also suggested that cannabis may be used in the setting of hypercoagulable states as may exist in patients with diabetes type 2.5. In other studies, CBD oil was found to affect platelets and anticoagulants by suppressing their production and thereby potentially increasing bleeding tendencies.” 
In simpler terms—research shows that CBD is a mild blood thinner. It could potentially exacerbate bleeding after surgery and slow down wound healing, especially if you suffer from any clotting disorder.
Cannabidiol furthermore gets metabolized via the same liver pathways as most prescription anti-coagulants. This effect is dose dependent, but it can affect the potency of the drug. (Research has shown that CBD increases serum warfarin, which could prove fatal.) 
Therefore, if you’re taking prescription blood thinners, always consult with your doctor before starting on any CBD regimen. They should insist on regular blood checks, as CBD and cannabis can decrease the degradation of especially warfarin in your body, and doses should be adjusted accordingly. If not, it could cause serious complications that would put your health—even your life—at risk.
If you are taking CBD together with any chronic medicine (especially those with a risk of drug-drug interaction), the rule of thumb should be to consult with your doctor for guidance days before uptake for surgery or any other hospital procedure.
Anesthesia is no joke. Your body literally gets paralyzed by powerful drugs (ergo the need for ventilators, because you cannot breathe by yourself while “under!”) before the surgeon takes to it with their blade. You don’t want to mess with this procedure.
For this reason, patients are always advised to disclose any chronic supplements and medication they take well before surgery, including cannabis and related products.
From a patient education pamphlet distributed by the Royal Victoria Regional Health Care Centre, Ontario:
“Anesthetic risk has many variables and is often related to your unique medical issues and specific surgery. Individuals who use cannabis do so in many ways, forms and amounts. Therefore, its effect on the body is difficult to predict when combined with a wide variety of anesthetic agents and techniques.
Currently, we do not have enough evidence to say that cannabis alone will increase your anesthetic risk when stopped at an appropriate time.” 
CBD Surgery—when Should You Stop Taking CBD?
If you’re not taking chronic medication, it gets somewhat easier.
At the Royal Victoria, patients are advised to stick to the following times for stopping any cannabis product:
Another doctor responder for the HelloMD forum sends this notice to her patients:
“If you ever do end up with surgery, you must discontinue your CBDs and your vitamin D3 approximately 48 hours before surgery. Both CBD and vitamin D thin the blood so typically surgeons would like to have you off anything that thins your blood for 48 hours before surgery. You may start in both medications again after surgery, typically when you’re released from the hospital.” 
Yet another doctor, the Chief Medical Officer of HelloMD, says this on the same forum:
“There should be no issue with you taking CBD the day before surgery, unless you are on blood thinners. CBD could perhaps prolong your bleeding time. As an anti-inflammatory it may even help with your wound healing. Depending on the time of your surgery, I would make sure that if you are taking a capsule that you observe the instructions by whoever calls you from the hospital regarding what time to stop eating and drinking fluids. You should not take the CBD after that time either. For post operative pain, you might want to consider using a 1:1 CBD:THC ratio tincture instead of an opioid, if one is prescribed by your surgeon. I would also let them know that you are taking it as well.” 
Get the idea? Cannabis, CBD, hospitals, and surgery are not simple and easy companions—and research is lacking, so there are no formal guidelines. Therefore, the safest route would always be to consult with your physician and disclose what you ingested well before surgery.
With CBD, hospital stays can surely be more positive, but is it safe to take CBD before surgery to help you through the ordeal? Get the whole picture here.
