Can CBD Oil Cause Dry Mouth?



CBD (cannabidiol) has gained popularity for its potential health benefits, but like any supplement, it can have side effects. One common side effect reported by users is dry mouth, also known as cottonmouth. In this article, we explore why CBD causes dry mouth, how to manage it, and provide answers to frequently asked questions.

Why Does CBD Cause Dry Mouth?

Several factors contribute to dry mouth after taking CBD oil or any cannabis-based product:

  1. Cannabinoid Receptors: CBD interacts with cannabinoid receptors (CB1 and CB2) located in the salivary glands. These receptors play a role in saliva production. When activated, they reduce saliva secretion, leading to dry mouth.

  2. Brain Signaling: CBD may signal the brain to slow down saliva production. Researchers believe that the central nervous system controls saliva production at the glandular level.

  3. Impurities: Contaminated CBD oils can contain harmful byproducts, causing irritation in the mouth and lungs. These contaminants contribute to dry mouth.

Coping with Dry Mouth

  1. Stay Hydrated: Drinking water helps alleviate dry mouth. Hydration is essential, especially when using CBD.

  2. Chew Gum: Sugar-free CBD gum or regular xylitol-containing gum can stimulate saliva production.

  3. Limit CBD Dosage: Adjust your CBD dosage to minimize dry mouth. Start with a lower dose and gradually increase if needed.


Dry mouth is a common side effect of CBD, but it’s usually temporary. Chronic or long-term use may lead to persistent dryness. Stay hydrated and be mindful of dosage. If discomfort persists, seek medical attention.
