How does CBD oil work?

Potential side effects

Dry mouth

Dry mouth, medically known as xerostomia, is a condition where the salivary glands in your mouth don't produce enough saliva. This lack of moisture can make it difficult to speak, eat, and swallow. It can also lead to bad breath and a diminished sense of taste. Over time, dry mouth can contribute to oral health issues like tooth decay.


Diarrhea is characterized by frequent, loose, or watery bowel movements. It can lead to dehydration if not managed properly, requiring the intake of fluids and electrolytes. Persistent diarrhea can also lead to nutritional deficiencies and should be discussed with a healthcare provider for proper diagnosis and treatment.

Reduced appetite

A reduced appetite can be particularly concerning, especially for children or individuals with preexisting health conditions. Less desire to eat can lead to malnutrition, weight loss, and exacerbation of other health issues. If appetite suppression continues, medical consultation is advised.


Drowsiness is not just about feeling sleepy; it's an overall sense of lethargy that can impair your ability to focus, think clearly, and react quickly. This can be particularly dangerous if you need to drive or operate heavy machinery. If you experience drowsiness while taking CBD, it may be necessary to adjust your dosage or consult a healthcare provider.


Fatigue goes beyond mere tiredness. It's a pervasive feeling of exhaustion that can affect both physical and mental well-being. This can interfere with daily activities, work performance, and even social interactions. If you experience fatigue while using CBD, it's crucial to consult a healthcare provider for proper diagnosis and treatment.

Low blood pressure

Low blood pressure, or hypotension, can manifest as dizziness, lightheadedness, and in severe cases, fainting. It can be particularly concerning for individuals already taking medications for blood pressure or those with cardiovascular issues. Immediate medical attention is advised if symptoms persist.


Light-headedness can be disorienting, making you feel like you're about to faint. It can be accompanied by nausea and may affect your ability to focus or perform tasks effectively. If you experience light-headedness while using CBD, it's crucial to consult a healthcare provider.

Interactions with other medications

CBD can interact with other medications you may be taking, such as blood thinners. This can lead to increased side effects or reduced effectiveness of your medications.

Purity and dosage concerns

There are also concerns about the purity and dosage of CBD in products, as some may contain less CBD than labeled and may include THC.


While CBD is often well-tolerated, it's essential to be aware of its potential side effects and interactions with other medications. Always consult your healthcare provider before starting any CBD products, especially if you are taking other medications or have concerns about the purity and dosage of CBD.
