Are you concerned about CBD oil side effects? You’re not alone. While many people use CBD oil for its health benefits, side effects can occur. This guide discusses potential reactions, ranging from mild and commonplace to rarer, more severe issues, empowering you with vital knowledge before you decide to use CBD oil.
Key Takeaways
CBD oil can cause side effects like dry mouth, low blood pressure, drowsiness, and gastrointestinal discomfort, which are generally mild and temporary; however, it can also lead to rare, severe side effects such as liver issues or worsened Parkinson’s symptoms.
While the FDA does not fully regulate CBD oil’s therapeutic claims, and interactions with other medications are possible, careful product selection and consultation with healthcare providers are critical before use.
Exploring CBD Oil Side Effects

CBD oil, sourced from the cannabis sativa plant, is considered a prospective remedy for numerous health conditions. However, while it offers potential therapeutic benefits, it also carries the risk of side effects. These side effects can vary greatly depending on the individual, the type of CBD product used, and how it is consumed.
The most common side effects associated with CBD oil use include:
Dry mouth
Low blood pressure
Drowsiness
Gastrointestinal discomfort
These adverse effects are typically mild and temporary, often diminishing as the body adjusts to the CBD oil. However, it’s important to note that everyone’s experience with CBD oil is different, and what may be a mild side effect for one person could be more severe for another.
One should realize that although CBD oil comes from the cannabis sativa plant, it doesn’t produce the ‘high’ typically associated with marijuana. This is because CBD oil does not contain THC, the psychoactive compound found in marijuana. However, some cannabidiol extracts sold online may include THC, which can cause psychoactive effects. Hence, it’s vital to verify that the CBD oil you’re using is sourced from hemp and contains less than 0.3% THC.
Before using CBD oil, it’s crucial to be aware of the possible side effects and interactions with other medications. This is particularly important for those who are considering using CBD oil as a dietary supplement. As with any new medication or supplement, it’s always best to consult with a healthcare provider before starting to use CBD oil.
Common Side Effects
Although CBD oil is generally tolerated well, it may result in some prevalent side effects. These typically include dry mouth, reduced blood pressure, and feelings of drowsiness. Some users also report relief from joint pain when taking CBD oil, although this effect is not universal. ²
CBD oil may also lead to gastrointestinal issues, such as diarrhea and vomiting. These side effects can be uncomfortable, but they are usually short-lived and disappear once the body adapts to the CBD oil. However, if these side effects persist, consulting with a healthcare professional is essential.
It’s also important to remember that everyone’s experience with CBD oil is different. Factors such as individual body chemistry, the dosage of CBD used, and the method of administration can all affect how a person reacts to CBD oil. Hence, starting with a modest dose and progressively increasing it until the anticipated effects are accomplished is paramount.
Rare and Severe Side Effects
Despite the common side effects of CBD oil being generally mild and transient, there exist some infrequent yet severe side effects that users should be conscious of. These can include liver abnormalities, exacerbation of muscle movement, and tremors in individuals with Parkinson’s disease.
While these severe side effects are rare, they can be challenging. Hence, it’s essential to recognize these potential risks before using CBD oil, particularly if you have pre-existing health conditions or are on other medications. Always consult with a healthcare provider before starting any new treatment, including CBD oil.
It’s also worth noting that:
The Food and Drug Administration (FDA) has only approved one CBD product, a prescription drug called Epidiolex, used to treat certain types of epilepsy. This makes Epidiolex the only CBD product approved by the FDA.
The FDA does not regulate other CBD products on the market, so their safety and effectiveness cannot be guaranteed.
Therefore, it’s crucial to choose CBD products carefully and always buy from reputable sources.
FDA Approval and Regulation of CBD Products
Although CBD oil holds potential therapeutic benefits, it’s necessary to realize that it’s not fully regulated by the Food and Drug Administration (FDA). Currently, the FDA has only approved one CBD product, a prescription drug called Epidiolex, which is used to treat certain types of epilepsy.
Epidiolex, a form of medical cannabis, is a cannabidiol (CBD) enriched extract derived from the entire cannabis plant. The FDA has sanctioned it in the United States for addressing seizures in individuals above the age of two diagnosed with Lennox-Gastaut and Dravet syndromes.
The lack of regulation for other CBD products means their safety and effectiveness cannot be guaranteed. Hence, choosing CBD products meticulously is essential and always purchasing from reliable sources.
Always consult with a healthcare provider before starting to use CBD oil or any other CBD product.
How to Choose a Quality CBD Product
With the escalating popularity of CBD products, the market is brimming with various options. But not all CBD products are created equal. It’s essential to choose the only CBD product that ensures quality so you’re getting the benefits you’re looking for.
When choosing a CBD product, consider the source of CBD. The quality of the hemp plant from which the CBD is derived can significantly impact the effectiveness and overall quality of the product. Look for products that use high-quality, organically-grown hemp.
It’s also vital to check for independent lab testing. A certificate of analysis (COA) from an independent laboratory can assure that the product contains the amount of CBD it claims to and is free from harmful contaminants. Additionally, the COA can provide information about the product’s THC content, ensuring that it is below the legal limit of 0.3%.
In Summary
CBD oil, an extract of the cannabis sativa plant, is a natural substance with a range of potential health benefits. From managing chronic pain to easing anxiety, it has shown promise in helping address a variety of health issues. However, knowing the possible side effects and interactions with other medications is essential.
Despite its potential, CBD oil is not a magic cure-all. Its effectiveness can vary significantly from person to person, and more research is needed to understand its potential benefits and risks fully. As with any new treatment, it’s crucial to consult with a healthcare provider before starting to use CBD oil.
In conclusion, CBD oil offers a promising alternative to traditional medications for many people. With its potential health benefits and natural origins, it’s no wonder that CBD oil has become such a popular wellness product. But as with any treatment, it’s essential to do your research, choose quality products, and consult with a healthcare provider before starting to use CBD oil.
