Can You Overdose on CBD Oil? [The Truth Exposed]

With the growing awareness about CBD, more and more people are showing their interest in using CBD products for treating their chronic pain, anxiety, insomnia, and many other medical conditions. The use of any medication or supplement always raises concern over overdosing. CBD oil is no exception. 

Different people are asking this question in different contexts. Some individuals are asking more generally to know if they can overdose on CBD without harming themselves. Some of them wonder if like many other medications, they can build a tolerance to CBD and can start overdosing.

However, many are asking this question in the context of its long time association with Marijuana and its psychoactive properties. So, they want to know if they can overdose by getting addicted to CBD.

Well, let us find out the answer to one of the trickiest questions about CBD from all the different angles.

What is Cannabidiol, or CBD?

CBD is the short form of Cannabidiol. It is one of the many compounds found in the Cannabis Sativa plant species. Marijuana and Hemp are the two most popular plants of this species. Apart from CBD, the plant contains over 400 compounds like THC, CBN, terpenes, flavonoids, and many phytochemicals. 

Is CBD Oil Addictive?

Since ages cannabinoids have been known to give you a feeling of high and have been used for recreational purposes. All the plant’s compounds derived from the cannabis plants were supposed to possess psychoactive properties.

However, the recent scientific studies have very categorically reported that only the THC derived from the cannabis plants give you the feeling of high. The studies have further clarified that CBD found in the plant does not contain any psychoactive properties.

All these studies have found out that though both THC and CBD interact with the human endocannabinoid system (ECS), they bind with its receptors differently to offer different results. While THC binds with the receptors that are associated with the nervous system of the human body, CBD links with those affecting the body’s immune system. 

So, neither does CBD possess psychoactive properties like THC, nor it is addictive. On the contrary, some studies have even reported CBD to reduce the psychoactive effects of THC and other addictive substances like heroin and opium.

Can You Develop a Tolerance to CBD Oil?

With prolonged use, you can develop a tolerance to some prescription drugs or even supplements. It means that the regular dose of the drug stops giving you the desired effects. As a result, you increase your dosage to get the effects that you were getting before. In some cases, the higher dosage so taken can be fatal. 

However, in the case of CBD Oil, there is no such evidence of building tolerance. In fact, the working of CBD in the body is quite contrary to traditional drugs. CBD interacts with your body ECS and links with its receptors. In this process, it actually triggers the natural ability of the ECS to produce more endocannabinoids. And as the body produces more cannabinoids naturally, it reduces the need to supplement it externally. So, you get relief with less dose of CBD over time.

That said, some individuals have reported a diminishing effect of CBD on their symptoms over time. In many of these incidences, shifting the time of using CBD Oil has improved the results. In some other cases giving CBD a break or limiting its use to SOS (take if necessary), has also improved the efficacy of CBD Oil. 

The research around the effects of CBD is still in a nascent stage, so it is important to consult an authorized physician for any alteration in CBD Oil dosage.

Can You Really Overdose on CBD?

CBD is not only non-psychoactive but is also non-toxic. What does that mean? It means that it is not a poisonous substance that can kill you. No fatality has ever been reported by using CBD.

It signifies that there are extremely low to no chances of overdosing CBD. Neither the compound in itself is toxic nor does it interact with the human physiology in a way to produce toxins in the body. Therefore, overdose on CBD cannot cause death.

Some people have reported the dangerous effects of using cannabis, but these incidences were not related to overdose on CBD Oil. In most of these incidences of mal-effects of cannabis, THC has been found to be the culprit.

People, in general, have good CBD tolerance. However, it is possible to have some adverse side effects after taking too much CBD in a single dose. Too much CBD consumption at one go can potentially cause side effects including,

  • Dry mouth
  • Dizziness
  • Drowsiness
  • Vomiting
  • Diarrhea
  • Mood swings
  • Lack of concentration
  • Anxiety
  • Depression and so on.

So, overconsumption of CBD does not have any hazardous effects, however, it can affect your efficiency and productivity to a great extent.

What amount of CBD Can You Take Safely?

Though most people have good tolerance of CBD, every individual responds differently to different doses. It is true not only with CBD Oil but also with other drugs and supplements. So, to determine the right dosage, you should begin by taking a small dosage of CBD. If you find that amount to be effective continue with the dosage. However, if you feel the dosage is not too effective, increase the dose gradually.

Now, the important question is to what amount you can increase the dosage that it does not show its side effects. The best guide value is the dosage recommended on the label of the CBD products. The second way is to consult your physician before increasing the dose.

For the academic purpose or to know how much quantity of CBD will be tolerable by humans if consumed accidentally you can refer to a 2011 study that indicates that up to 1,500mg of CBD per day is pretty tolerable.

Can Your Pets Overdose On CBD Oil?

CBD is not only an alternative healing substance for humans, but animals are also getting benefitted by the use of CBD products. In fact, the market for pet CBD products is growing significantly with each passing year and is expected to cross the $1bn mark by the end of the year 2022 in the USA itself.

There is a wide variety of CBD products available in the pet supplement category including oils, tinctures, creams, and treats, and so on. Similar to humans, pets also get many health benefits like relief from chronic pain, inflammation, anxiety, and seizures to name a few. So, people are interested in knowing about the effect of giving too much CBD to their pets as well. 

Though there have been no casualties yet reported on overdose on CBD to the pets, there are increasing incidences of CBD overdose reported by the Animal Poison Control Center (APCC). These symptoms are similar to THC overdosing in animals. These symptoms include:

  • Dullness
  • Irritation
  • Diarrhea
  • Vomiting
  • Change in appetite
  • Loss of control over Urination
  • Uncoordinated movements and many more

So, there are two important factors to consider while administering CBD to pets. The first and foremost is that the dosage should be given strictly as recommended by the manufacturer. So, check the CBD product label for the suggested dosage.

The second is to buy the product from the reputed seller to ensure that the CBD product for your pet is free from THC or any other harmful impurities.

What is the Right Way of Using CBD Oil?

Though we realized that overdose on CBD does not create any dangerous situation yet it is advisable to follow the recommended dose to avoid any adverse side effects caused by overdosing. Besides, it is also important to take CBD Oil as per the instructions provided on the product label.

For instance, the instruction to shake the bottle before the use is important because it allows the CBD to blend well with the oil which gets settled at the bottom of the bottle during storage. Shaking the bottle ensures uniform potency of CBD Oil in the entire bottle. In case CBD settles down at the bottom, CBD content in the oil will be minimum at the top and maximum at the bottom. So, despite taking the right dosage you will actually not be consuming the required amount of CBD with each dose. On one side, it will reduce the effectiveness of CBD Oil and on the other side, it will cause overdosing.

Also, you should take care that you properly fill the dropper and also dispense it fully under your tongue. You should allow it to stay under the tongue for a minute or as instructed. Taking it sublingually helps the oil to absorb in the bloodstream quickly. This offers quicker and more effective results of taking CBD Oil. So, you get the benefits of CBD with lesser quantity as compared to swallowing it directly to get into your bloodstream via the digestive system.

This indirectly prevents you from consuming more quantities of CBD and, in turn, any possibility of overdosing.

What Other Precautions to Take While Using CBD Oil?

Studies about the health effects of CBD products are still in the nascent stage. If you get some side effects by not taking due precautions you can doubt the very effectiveness of CBD. With this misunderstanding, you may also stop using CBD and will eventually bereave yourself of its health benefits. And for this reason, it is essential to take due precautions while taking CBD.

Consult a physician

Consulting a qualified physician before taking CBD products can save you from many problems.

The physician can guide you to buy CBD Oil from genuine suppliers and can recommend to you the right dosage as per your health and medical condition. Furthermore, in case you feel any discomfort, your physician can suggest proper action to mitigate it quickly.

Consume on a full stomach

Consuming CBD empty stomach can also cause problems like diarrhea. So, consume CBD after half an hour of having food. This not only helps to prevent the side effects of CBD but also increases its bioavailability, thus increasing CBD absorption in the body. Increased effectiveness of CBD Oil avoids going for a higher dose, in turn, prevents the possibility of overdosing. 

Method of Consumption

If direct consumption of CBD Oil shows any symptoms of a side-effect, particularly related to the digestive system, you can mix it with a beverage or a recipe. However, if your digestive system is highly sensitive it may react even with the changed method of consumption. 

In such a situation, using the Topical method can be beneficial particularly for any pain condition or skin issues. This will also completely eliminate the possibility of overdosing.

Check for the other ingredients

CBD Oil preparation requires the use of some carrier oil like coconut oil, olive oil, or hemp oil. Particular carrier oil used in preparing CBD Oil can also give side-effects to some individuals. Besides, some colors and flavors are added to the product to mask the raw color and the smell of CBD. They can also cause some allergies. Check the product label to find out if you are allergic to any of the ingredients used in the product. Buy the CBD Oil which does not have those additives.

If you still observe some symptoms of a side-effect, you can try changing the CBD brand with a different set of ingredients.

Buy from a reputed brand

A reputed company puts a lot of effort into promoting its brand image in the market. It cannot afford to take the risk of spoiling it by selling inferior quality products. So, always procure your CBD from a renowned brand or company.

You must conduct thorough research and refer to consumer reviews before buying CBD Oil. 

Besides, you should request the third-party testing report from the seller to check for the presence of heavy metals, chemicals, THC levels, and the composition of CBD Oil. This will prevent you from buying an impure product that can subsequently cause serious repercussions to your health.


Through various scientific studies, it is clear that CBD does not possess any psychoactive properties and is non-toxic and not addictive. Besides, there is no evidence of building a tolerance to CBD Oil. Furthermore, even consuming 1500mg of CBD at once has not reported any fatality.  

Evaluating all these study reports, we can clearly observe that there is no concrete evidence of any dangerous effects of overdosing CBD Oil. Yes, there are some reports that suggest that taking too much CBD can cause some side effects like diarrhea, nausea, vomiting, dizziness, drowsiness, anxiety, and depression, etc.

Also, though overdosing CBD does not create any hazardous situation, impurities like THC, if present in CBD, can pose a serious threat to your life if over-consumed.

Therefore, until there is close monitoring of the Food and Drug Administration (FDA) over the processes of manufacturing CBD Oil, it is advisable to take due precaution to safeguard yourself from its side effects.
