CBD oil is seen to be beneficial to many individuals across the United States. It was after the legalization of hemp cultivation and commercial use. The amount of CBD oil to be consumed by an individual depends on various factors that need to be considered. This article explains whether an individual can take too much CBD oil.

It is natural for someone experimenting or starting to use CBD to ask this question. Normal over-the-counter drugs have information on their levels and the manufacturer’s manual about the stipulated dosage one should follow. Individuals are taught in school how to follow doctors’ instructions. Most users of CBD products do not discuss their prescription with doctors or use products that are ideally felt as snacks to manage their conditions. While CBD has made these freedoms achievable by users, it causes people to question whether they are consuming too much CBD oil in a product. Are you one of them? This article will discuss how much CBD is and safety precautions to exercise while using CBD.


Taking too much of something is when you have taken more than the agreeable or recommended amount of a particular drug or medication. Like any drug, it can take more CBD oil than your body can handle. It is shown that a total amount of 1500 milligrams a day is well tolerated by most people. Cyr et al. (2018) stated that CBD does not significantly inhibit brainstem-like opioids from causing a fatal reaction when taken in high doses. The brainstem is the part of the brain that controls your heartbeat, blood pressure, breathing, body temperature, and digestion. A high amount of general drugs cause a fatal overdose as the brain contains many opioid receptors. Increased stimulation of these receptors slows down your heartbeat and eventually your breathing. Chen et al. (2017) stated that the lower brainstem has fewer cannabinoid receptors. CBD is thought to bind with these receptors when consumed by users. So, if you take too much CBD oil, there will not be enough cannabinoid receptors to bind to and activate to affect your health adversely. While that seems good, ingesting too much CBD can use intolerable side effects. Cabral et al. (2015) explained that these side effects include dry mouth; this happens as CBD activates cannabinoid receptors in the mouth, causing a decrease in saliva secretion. Others are nausea, diarrhea, upset stomach, lightheadedness, and drowsiness caused by CBD adversely lowering the blood pressure. High ingestion of CBD might cause significant relaxation of blood vessel walls and general body disorientation. Some studies on lab rats after ingesting too much CBD confirmed liver damage. It is also a health side effect if one ingests too many CBD products. It is important to be advised by a doctor who will offer a prescription when adding CBD to help your general healthcare.


Interestingly there is no conclusive answer to how much CBD is considered too much. Taylor et al. (2018) explained that taking a whole bottle of highly concentrated CBD is tolerable. The researched patients used the highest amount of CBD daily and did not show significant side effects. Another study was conducted on CBD’S tolerability and safety. The results of these studies were that at increasing the doses between 1500-6000 mg, most participants still tolerated CBD oil. Proper dosage varies from person to person as people react differently to CBD products. MacCallum & Boivin (2021) explained that starting with low doses and concentrations of CBD is always recommended as your body builds tolerance for a high dose and concentration. This way, you will find your optimal dose. Carry out the process while evaluating yourself after feeling its effects. Most brands offer their recommendations of how much CBD you should take. When you start CBD, check in the labeling or drug manual how much has been advised to be ingested in one taking and after how long. If purchasing from a CBD company, ask for information. Experts advise that to strike a good balance with your body’s system, consider sticking to a dose between 50-200mg. While the lethal dose of CBD has not been established, its toxicity threshold likely needs to be significantly exceeded to cause severe consequences.


Taking too much CBD cannot kill someone. The side effects, as discussed, are less severe than ingesting high doses of over-the-counter drugs or marijuana. Individuals should try and stay hydrated, make themselves comfortable, and wait for some time to pass. If the effects are too uncomfortable, call 911 or, if possible, go to the nearest medical facility with the CBD product you have consumed to be checked. After that, experts recommend taking a 3-5 day break from consuming any CBD products. It will trigger your body system to come back to its normal well-being. Your tolerance of CBD may be higher after this scenario. The break plus a cut of your dose to half might help reset your tolerance. Lastly, consider starting back to a lower dose.


The odds of having a fatal reaction after taking too much CBD oil are improbable. However, consuming too much CBD might cause adverse reactions, including liver damage. It is important to work out a reasonable dosage and evaluate how your body reacts to CBD products. Also, consider taking products that already have a prescribed dosage, including pills, capsules, and tinctures. They decrease the chances of using too much CBD adversely. An important note to consider is always to remember to purchase products from reputable sources to avoid purchasing a product that is expired or contaminated. Also, labels have information about products’ terms of use. Reading these guidelines might help achieve an optimum dosage for you. Food and Drugs administration does not regulate these products; it is therefore upon you to make the right choices with the information at hand.
