Side Effects of Taking CBD Oil - Read This Guide Carefully

Dryness Of The Mouth

Cannabinoids, like CBD and tetrahydrocannabinol (THC), which is a primary component in various marijuana strains, can induce dehydration among users. The lack of moisture can lead to a phenomenon wherein the users experience a feeling of “cotton bulls stuffed in the mouth”. 

Also called “cottonmouth”, this scenario can be an adverse effect of using specific CBD oil products. But, it shouldn’t be life-threatening, and users can quickly remedy this effect by drinking water or other hydrating fluids. 

The reason behind this phenomenon is because when someone consumes a cannabinoid, the receptors in the endocannabinoid system (ECS) cease functioning, particularly the receptors in the salivary glands. Hence, the body briefly stops the secretion of saliva in the mouth. 

Different CBD oil products may produce different intensities of this adverse effect. Visit this webpage to check the different CBD-infused products that may or may not lead to mouth dryness.. 

Low Blood Pressure

People diagnosed with hypertension can seek the help of CBD oil to help them in lowering their blood pressure back to normal levels. 

But, high doses of CBD oil might cause drops in blood pressure deemed lower than average. Hence, it might be cumbersome for high blood pressure patients to use CBD oil and other medications to lower blood pressure. It is for the reason that this natural substance can lower the blood pressure to severely low levels. 

Other side effects linked to this phenomenon may include lightheadedness, headaches, and nausea. Therefore, it’s paramount to consult with a doctor before using any CBD-infused product, especially if a patient is under prescription medicine for high blood pressure. 


Patients experiencing particular physiological or psychological discomforts may use CBD oil for the relief or treatment of their health concerns. CBD can be an excellent choice to relieve pain, improve anxiety-related symptoms, and alleviate discomfort from cancer treatments. 

This naturally-occurring compound interacts with the receptors in the ECS to normalize different imbalances in the body. In turn, the body and mind may fall into a state of relaxation, which might proceed to sedation if the patient consumes CBD at high doses. 

Thus, it might be beneficial for CBD users to consume the substance away from times of work. But, this potential adverse effect may also work in favor of the consumer. 

People experiencing insomnia may use higher-than-average doses of CBD oil to incur a good night’s sleep. The calming effect may also help relieve other pain-related symptoms, causing the individual to have peace of mind while blissfully sleeping at night. 

Digestive Issues

CBD oil may interact with the digestive system negatively. The substance may cause concerns, such as:

  • Diarrhea
  • Nausea
  • Vomiting
  • Unexplained weight gain or loss
  • Increased or reduced appetite

However, it may seem that CBD isn’t the culprit for these digestive issues. One study explains that CBD helps improve health concerns like diarrhea and nausea instead of causing them. So, patients experiencing these adverse effects might have stemmed from the consumption of CBD products infused with carrier oils, like unrefined coconut oil, avocado oil, and sunflower oil. 

Another study sees that CBD oil may interact with specific supplements, causing digestive issues to consumers. The consumption of supplements with harmful contaminants, like heavy metals, pesticides, and solvents, might be the primary culprit to the adverse interaction of CBD oil in the body. 

Consumers experiencing digestive issues from consuming CBD oil should consult their doctors immediately. The medical professional may recommend solutions, such as reducing the dose, shifting to another CBD brand, or taking alternative supplements. 

Slowed Movement

The calming effects of CBD oil might deliver adverse results to the consumer’s motor skills. Seemingly basic movements, like walking, moving the hands, or standing up, might take longer than average to accomplish. 

But, this side effect may only exist on individuals with other severe underlying illnesses, like Parkinson’s disease. Doses of 300 mg/day or above may promote symptoms like resting tremor and hypokinesia, which is a disorder wherein a significant reduction in speed and efficiency of movement becomes apparent. 

However, that adverse effect might not exist in all patients with Parkinson’s disease. One study in the Journal of Psychopharmacology states that CBD oil can improve the quality of life of patients with this disorder. 

Thus, it goes to show a requirement for more clinical research is evident because of the mixed results produced by CBD oil among Parkinson’s disease patients. 

Increased Anxiety

Mental adverse effects may also surface among CBD oil consumers, mainly when they consume CBD products with THC. THC is the component that is responsible for the mind-altering or psychoactive effects of marijuana.

Some CBD products have THC in them, albeit at an amount no higher than 0.3%. Nonetheless, that seemingly minuscule amount may impact the mental stability of the consumer negatively. The consumer may experience a slight increase in anxiety-related symptoms, which may dwell into mild psychosis. 

Is It Safe To Use CBD Oil?

Be careful when buying CBD online or from brick-and-mortar stores. Some retailers will sell low-quality CBD oils, which may increase the risk of the adverse effects mentioned above to surface in the bodies of consumers. 

Don’t hesitate to invest in high-quality CBD oil to reduce the risk of adverse side effects from appearing. However, some minor adverse effects, such as dry mouth and lightheadedness, may still appear in consumers. But, these results tend to be temporary, and users can remedy these concerns without taking other medications or visiting their doctors. 

Nonetheless, it’s critical to visit an experienced medical professional if the adverse effects of using CBD oil persist for extended periods. Don’t take these effects for granted; otherwise, these negative results might lead to other health complications.
