Dry mouth is frequently reported as a prevalent side effect of CBD and other cannabis-based products. In this article, we will explore the mechanisms by which CBD induces dry mouth and provide practical tips on mitigating this discomfort.

How does CBD cause dry mouth?

Dry mouth, also known as xerostomia, is a common side effect reported by some individuals who use CBD. CBD interacts with the endocannabinoid system, which plays a role in regulating various bodily functions, including salivation. While research on this specific side effect is limited, anecdotal evidence suggests that CBD may reduce saliva production, leading to dry mouth in some users. It typically occurs due to CBD interacting with the endocannabinoid system, which can alter the flow, consistency, and composition of saliva.

How to control Dry mouth after using CBD?

If you experience dry mouth after using CBD, there are several strategies you can try to alleviate the discomfort:

  1. Stay Hydrated: Drinking plenty of water can help counteract the dryness in your mouth. Carry a water bottle with you and take sips throughout the day.
  2. Chew Gum or Suck on Candy: Chewing sugar-free gum or sucking on sugar-free candy can stimulate saliva production and relieve dry mouth.
  3. Use Moisturizing Oral Products: Consider using moisturizing mouthwashes, lozenges, or sprays designed to alleviate dry mouth symptoms.
  4. Limit Caffeine and Alcohol: Both caffeine and alcohol can contribute to dehydration, and promote dry mouth. Limit your intake of these substances.
  5. Opt for Humidifiers: Using a humidifier in your living or sleeping space can add moisture to the air, helping to reduce dry mouth symptoms.
  6. Choose CBD Products Wisely: If you consistently experience dry mouth with a particular CBD product, consider trying a different form or brand. Experimenting with various consumption methods might help you find one that minimizes this side effect.
  7. Adjust CBD Dosage: Lowering the CBD dosage may help reduce the severity of dry mouth. It's advisable to start with a lower dose and gradually increase it while monitoring your body's response.

Remember that individual responses to CBD can vary, and what works for one person may not work the same way for another. It's essential to listen to your body and make adjustments as needed. If dry mouth is accompanied by other concerning symptoms, or if you have pre-existing health conditions, consult with an expert for proper guidance.
