Can You Overdose on CBD Oil? Ask a Pharmacist

Can You Overdose on CBD Oil? Ask a Pharmacist

Posted by Dr. Leslie Mudd, PharmD on Apr 30th 2020

After reports that people in legal marijuana states have gone to the Emergency Room after taking too much THC while snacking on edibles, some people worry that taking too much CBD may have a similar effect. It has led many people to ask: Can you overdose on CBD? What happens if you take too much CBD? How much CBD should I take? This post will answer these questions.

First, let’s define a few CBD terms. The term “overdose” can have a few different meanings. "Overdose" can mean something serious things like taking a potentially lethal amount of a drug, whether prescription or illegal. "Overdose" can also just mean accidentally taking two doses instead of one. Or, when a person’s body has a bad reaction and they assume it was because they took too much CBD. When someone asks about an overdose, it helps to know their definition of the term and the context in order to give the best possible answer.

Is CBD Oil Addictive?

To date, there is no study published showing that CBD could be addictive, nor that it has a dependence potential. Studies also show that the CBD compound does not get you high, which further lowers the risk of possible harm from CBD.2 That means that CBD has a much lower chance of becoming habit-forming, and that there is little risk that someone could overdose on CBD.

Can You Build a Tolerance to CBD?

When people develop a tolerance for something, it means that their body gets used to that compound, which requires more to get the same effects, like needing an extra cup of coffee.4 This could compel a person to take more of it to obtain the same feeling. As the amount of CBD per day increases over time, this may lead to unwanted side effects if they take too much CBD.

Anecdotally, some people claim that CBD has less an effect on them as it did previously, or that it took longer to work, which could be an indication of increased tolerance. This issue can potentially be resolved by taking CBD at a different time of day, taking a short break, or only taking CBD periodically to address a specific need.5

This could be different for someone who is used to full-strength cannabis products, or someone with a history of marijuana use, because they have previously been introduced to cannabinoids. These sorts of cannabis experiences can change how legal cannabidiol products work for you. By ingesting any sort of cannabinoid, whether it be rich in CBD or THC, the regular use of a cannabis product may result in a different experience than that of a first time CBD user.

For folks who may have reached a plateau from CBD isolate or broad spectrum CBD products, switching over to a full spectrum CBD oil can prove as an effective kick-start. For those seeking comfort from problematic muscles and joints, our CBD balm can be an effective treatment as it is infused with organic peppermint oil and arnica oil.

Bottom Line:Can Humans Overdose on CBD Oil?

To date, there has been no study published or any reports about an overdose on CBD oil, to our knowledge.* However, it is certainly possible to accidentally take too much CBD than is recommended and experience some mild discomfort.

That's one big reason why Cornbread Hemp products contain graduated droppers, to be able to easily measure the proper serving size. The variables involved in determining one's proper serving of CBD include weight, diet, sex, and age. To learn more about correct dosing, and to avoid taking too much CBD, check out our CBD dosage guide.

Can Pets Overdose on CBD?

No reports have surfaced in the United States to our knowledge about pets being injured by taking too much CBD oil have surfaced in the United States.* Pets react to CBD in much the same way as humans.7 Pet owners just have to keep in mind the proper dosage for their pet's body weight. Then they must figure out the best way to give it to their furry companion, whether they will take a capsule or lick the oil, or if it must be added to food.

Like humans, pets who use CBD may find comfort in the wholesome full spectrum hemp compounds extracted from CBD-rich cannabis flowers. These CBD-rich extracts contain small amounts of THC, enough to be effective but not enough to cause harm to pets. That's why pet products containing CBD oil have become so popular among pet lovers.8 

If you’re still wondering where to start with your pet and CBD oil, look for the nearest holistic veterinarian in your area. Also, never shop for CBD oil for the first time on Amazon. Most of these products are merely a blend of hempseed oil and coconut oil, and they do not contain any actual CBD.

Effective Dosing of CBD for People

The real question is what the most effective dose of CBD is. What is the best dosage? CBD taken orally is subject to the digestive process. Does it matter if CBD is taken with or without food? Some CBD preparations may be better absorbed with a high fat meal. Is there anything else in the CBD that might affect how it works or how CBD makes you feel? Researchers are looking for the answers to these questions, and we hope to be able to speak more about them soon.

For now, follow the instructions on the label of your CBD product. CBD that has been produced according to the federal requirements of less than 0.3 percent THC should not produce any intoxicating effects.9 If you are taking the product on the advice of a healthcare provider, follow your doctor's orders.

We recommend to most CBD first timers to start with one full dropper per day of our original formula. Our products are designed to easily be able to measure a 25 mg dose of CBD per serving. With the addition of our 1,500 mg CBD oils, Cornbread Hemp customers can now enjoy a 50 mg dose of CBD per dropper of CBD oil, or four equal parts at 12.5mg of CBD.

Does CBD Oil Have Side Effects?

It’s important to understand that CBD is not a drug and is considered by health care practitioners to be a natural supplement, much like fish oil, so it cannot be described in medicinal terms. However, just like with dietary supplements, we can say that CBD may have risks associated with it. Some people may experience negative side effects like dry mouth or nausea if they take too much CBD oil, and those with a hemp allergy would want to avoid hemp based products all together. There is also a potential for drug interactions with certain prescription medications, so you will want to make sure to check with your doctor if you are taking medications.

Additionally, fake CBD products or low-quality products may have harmful ingredients that can cause negative side effects. In order to make sure you don't end up wasting your time and money on products that are unsafe or ineffective, make sure to properly research the CBD company you purchase from. Check for third party lab reports to make sure you are getting a safe, potent product.

Choosing a CBD Oil Brand You Can Trust

The bottom line is that there are zero reports of a person overdosing on CBD. But that doesn’t mean that CBD is totally harmless. Some disreputable CBD brands have been shown to contain dangerous contaminants like pesticides and heavy metals. One report suggests that 70 percent of CBD products contain dangerous contamination.11

The only way to ensure that a CBD oil is free of pesticides, heavy metals, solvents, and microbial contaminants is to look for CBD oils that are certified organic and third-party lab tested like the CBD oils made by Cornbread Hemp. Not only do we test for pesticides and heavy metals, but we also grow our hemp under the authority of the United States Department of Agriculture's organic program, which requires our operations to remain completely free of any potential non-organic contaminants.

Organic farming requires a crop rotation that usually consists of three to four different organic crops that rotate on different areas of land each season. These rotated crops regenerate the nutrients in the soil, which gives us a much better yield in the long run, while also replenishing the nutrients and minerals that our next crop will depend on.

Hemp is a natural bio-accumulator, meaning is absorbs much of the nutrients, toxins, and other elements within the soil that surrounds it. If we didn't regenerate the soil's nutrients, we would have to replace them with chemicals, just like our competitors do.

It’s extremely important to grow the hemp used in your CBD oil without the use of pesticides. And, it's equally important to regenerate the nutrients naturally that are essential to growing the most CBD-rich hemp genetics in the world. That’s what we refer to as “regenerative agriculture.”

Why Cornbread Hemp?

Since the Farm Bill of 2018 passed Congress, products containing CBD may be everywhere from gas stations and coffee shops, to health food stores and pharmacies. And you can find CBD in many different forms: from oils, to CBD gummies, capsules, and more. But with so many products saturating the market, it can be hard to find a genuine, high quality CBD product that you can trust.  

By committing ourselves to using only the highest quality, pesticide-free organic hemp, and by administering third party lab tests, Cornbread Hemp ensures our customers will receive the safest and most effective organic CBD products available on the market. We recommend that you do your own research on CBD products, in part by reading the reviews about CBD on the Cornbread Hemp website.

Can You Overdose on CBD Oil FAQ's

Can CBD oil get you high?

No, CBD oil does not get you high. Full spectrum CBD oils contain trace amounts of THC that must be below 0.3% by law. That's not nearly enough THC to get you high. Even if you take more CBD than you should, you will not get high. CBD interacts with the way that THC binds with the receptors in your body, and CBD can actually lessen the effect of THC. So, bottom line- CBD does not get you high.

How does CBD oil make you feel?

Many people report noticing the impact of CBD after they stop taking it for a regular period of time. However, this is often dependent upon whether your CBD oil contains a full spectrum of cannabinoids, or just CBD isolate. Just know that you cannot overdose on CBD, the worst you can do is make yourself feel some uncomfortable side effects if you take too much CBD.
