The Science Behind CBD and Dry Mouth

Before we dive into the nitty-gritty, let’s understand why CBD might cause dry mouth. CBD, or cannabidiol, is a compound found in cannabis that interacts with our body’s endocannabinoid system (ECS). This system plays a crucial role in regulating various physiological processes, including saliva production.

How CBD Interacts with Salivary Glands

Research suggests that cannabinoids, including CBD, can influence saliva production. A study conducted in 2006 found that cannabinoid receptors, specifically CB1 and CB2, are present in the submandibular glands, which are responsible for producing about 60-67% of our saliva.

These receptors interact with cannabinoids produced by our body, such as anandamide, which can inhibit saliva secretion. CBD and THC, the primary cannabinoids found in cannabis, interact with these receptors in a similar way, potentially leading to a dry mouth sensation.

CBD’s Influence on the Brain and Saliva Production

Interestingly, the ECS’s role in saliva production isn’t limited to the salivary glands. The same 2006 study suggested that cannabinoids might also interact with the cannabinoid receptors in the brain, influencing saliva production at a central level.

Potential Causes of Dry Mouth from CBD

Now that we’ve covered the science, let’s look at some potential reasons why CBD might cause dry mouth.

Contaminated CBD Oil

Impurities in CBD oil can lead to irritation in the mouth and lungs, potentially causing dry mouth. Always ensure your CBD oil is pure and free from harmful contaminants. If you experience severe dryness, itching, or swelling, stop using the product and seek medical attention immediately.

High Doses of CBD

Taking high doses of CBD (more than 100 mg) can lead to side effects like dry mouth, dizziness, changes in appetite, and fatigue. Always start with a low dose and gradually increase it to find the optimal dosage for you.

Smoking and Vaping Cannabis

Smoking or vaping CBD can cause dry mouth and irritation in the mouth, throat, and lungs. This is because the inhaled CBD directly interacts with your salivary glands, reducing saliva secretion.

Sublingual CBD Products

Sublingual CBD products, such as oils and sprays, can have a stronger effect on your salivary glands as they are taken under the tongue. While this method allows CBD to enter the bloodstream faster, it can also inhibit saliva production, leading to dry mouth.

Managing Dry Mouth from CBD: Tips and Tricks

Experiencing dry mouth from CBD doesn’t mean you have to stop using it. Here are some tips to help you manage this side effect:

  1. Stay Hydrated: Drink plenty of water throughout the day. You can also drink hydrating liquids like herbal teas or electrolyte-rich drinks before taking CBD to help offset dry mouth.

  2. Stimulate Saliva Production: Eating something sour or sweet, like a lollipop or gummy, can stimulate saliva production. Brushing your teeth can also help.

  3. Chew Gum: Chewing gum, especially those flavored with peppermint essential oils and xylitol, can stimulate your salivary glands and increase saliva production.

  4. Eat Fruit: Fresh fruits, especially citrus ones, can help reduce dry mouth sensation. Chewing on dry fruits or ice cubes can also stimulate saliva production.

  5. Try Different Forms of CBD: Some forms of CBD, like capsules or topicals, are less likely to cause dry mouth. Experiment with different forms to see what works best for you.


So, does CBD cause dry mouth? The answer is, it can. But with the right knowledge and some simple management techniques, you can continue to enjoy the benefits of CBD without the discomfort of a dry mouth. Remember, always choose high-quality, pure CBD products and start with a low dose. Stay hydrated, stimulate your salivary glands, and don’t be afraid to try different forms of CBD. Happy hydrating! 😊
