The Science Behind Cotton Mouth
Before the onset of cannabis legalization that led to the wide selection of products seen in dispensaries today, recreational smoking was the primary method of use. In those times, many believed cotton mouth was caused by the thick smoke that resulted from burning cannabis. However, as users began vaping as an alternative to smoking, cotton mouth remained to be a side effect. As capsules, oils, and gummies began to make an appearance, those products also carried with them the same results. The question behind why cotton mouth occurs could only be answered when scientists began to study the problem .
Dry mouth as a side effect of consuming cannabis is fairly common, and most refer to it as “cottonmouth,” though the scientific name for dry mouth is “xerostomia.” In 2006, Juan Pablo Prestifilippo and his colleagues at the Centro de Estudios Farmacologicos y Botanicos in Buenos Aires searched for potential causes of cotton mouth, specifically, a decrease in saliva secretion. The team theorized that there are cannabinoid receptors located in the salivary glands which are responsible for this effect. Experiments on male rats determined receptors CB 1 and CB 2 were present in specific locations of the submandibular gland – a salivary gland in rats. It was discovered that the cannabinoid anandamide attaches to these receptors, resulting in hyposalivation (decreased saliva output) .
Olga Kopach and Juliana Vats at The State Key Laboratory of Molecular Biology in Kiev found that normally, the cells of saliva glands use the endocannabinoid system to signal feedback that inhibits the over accumulation of saliva in the mouth. When a person consumes cannabinoids, receptors CB 1 and CB 2 bring about a significant drop in saliva production, causing the mouth to feel dry. Kopach also reported findings that these receptors behave differently at the cellular level. “CB 1 receptors predominantly modulate the flow of saliva, while CB 2 receptors seem to influence consistency and content of saliva (such as sodium levels) . . . Cells in the salivary glands can synthesize anandamide” . Dry mouth from consuming cannabis does not cause dehydration throughout the rest of the body, which is why it does not cause the type of hangover some experience from alcohol consumption. Interestingly, what scientists have learned about how the salivary glands and cannabinoids interact could lead to new therapies for those who experience complications with salivation .
Is Cotton Mouth Dangerous to Health?
A collection of research out of the Department of Periodontology at the Academic Centre of Dentistry in Amsterdam suggests that with increased cannabis use 4 , oral health is a concern. The researchers stated that providers of oral health care need to be more aware of the potentially chronic side effects associated with dry mouth from cannabis consumption. Mainly, these are:
- Leukoedema – “A white or whitish-gray edematous lesion of the buccal and labial oral mucosa” .
- Candida Albicans – A type of yeast present in microbes on the skin (including inside the mouth) and gastrointestinal tract that is healthy at normal levels but harmful when multiplied. In that case, it becomes known as thrush, or Candida overgrowth .
- Periodontal Disease – An infection of the gums that can cause bad breath, swollen or red gums, bleeding or tender gums, pain when chewing, loss of teeth, sensitive teeth, and receding gums .
- Tooth Decay and Cavities8
Saliva lubricates the mouth so that we can taste food, swallow, and speak. It also protects the mouth, throat, and teeth from bacteria, viruses, and other microorganisms. As such, saliva levels that are consistently low become a risk factor for tooth decay, cavities, periodontal disease, and even tooth loss . Less serious side effects include: feeling thirsty, hoarseness, sore throat, tingling in the mouth, a raw or red tongue, cracked lips, mouth sores, and skin that is split in the mouth . While marijuana is not the only medicine that may result in xerostomia, hyposalivation is typically solved when the user stops taking the problem medication, such as with radiation treatments for cancer patients. On the other hand, those who consume cannabis tend to do so frequently and consistently over longer periods of time. Understanding ways to prevent or cure cotton mouth is key to avoiding these harmful side effects .
How to Prevent Cotton Mouth
The American Dental Association encourages consumers of cannabis to maintain regular visits with a dentist, chew sugar-free gum, and maintain a regimen of teeth brushing at least two times per day using fluoride-enriched toothpaste. Some other health professionals have suggested a reduction in citrus-based foods and alcohol-based breath sprays, beverages, and mouth wash because they can dry the mouth. Some drug stores carry gums and sprays that help keep the mouth moist and are a good idea for those who consume cannabis on a regular basis or who tend to experience cotton mouth . Gum chewing helps by preventing signals from the endocannabinoid system that limit saliva production.
Another obvious cure for dry mouth is to drink water, especially while consuming cannabis. While it may be tempting to have a refreshing beer or wine, those beverages contain tannins that can further dry the mouth. Some fruit juices and teas may also contribute to the problem. The important part is to sip on water throughout the day or before, during, and after cannabis consumption. Even drinking water will not be as effective once dry mouth has set in. Some prefer to eat crushed ice as a means to break up the monotony of drinking water .
In an article published by American Marijuana titled, “Cannabis & Cotton Mouth – Get Rid of Marijuana Dry Mouth,” Dwight Blake provides the following additional remedies for cotton mouth:
- “Sipping water frequently especially with a straw keeps you hydrated.
- Chewing gum, beef jerky or dried fruit stimulates the release of saliva.
- Lick lollipop or suck on some hard candy. These stimulate saliva production – sour flavors are usually better for increased saliva production.
- Cough medicines, which are also known as demulcents, help reduce dryness of the mouth by covering the mucus membrane with a dewy film.
- Herbal teas help reduce the dry feeling on the throat” .

The Potential Side Effects of CBD
CBD: Benefits and Side Effects
Wendy Rose Gould is a lifestyle reporter with over a decade of experience covering health and wellness topics.
Generally speaking, CBD is considered a safe substance when applied topically or taken orally. There are, however, some potential side effects to keep in mind when using this substance, the majority of which are mild.
Common Side Effects of CBD
The most comment side effects of CBD include drowsiness, gastrointestinal issues, dry mouth, reduced appetite, nausea, and interaction with other medications. Those are outlined in detail below.
Some common side effects when using CBD include drowsiness and sedation. This is also considered a benefit, but Dr. Jas Matharu-Daley, a physician and chief medical officer for a CBD brand, notes that the effects might be too strong if you’re also taking CBD with other sedating medications.
Some people may get diarrhea or liver problems [when using CBD]. This is dependent on the individual and their medical history, so monitoring is important,” says Dr. Matharu-Daley.
Also known as “cotton mouth,” CBD can potentially cause your mouth and eyes to feel very dry, notes Dr. Brent A. Bauer via Mayo Clinic. Though this side effect is more likely to occur with THC, it can happen with CBD, as well.
Can Interact With Other Medications
CBD might interfere with the other medications you take. Dr. Matharu-Daley says it’s important to talk to your doctor about whether CBD could affect your existing prescriptions.
In some cases, those who ingest CBD supplements might experience nausea, says Dr. Matharu-Daley. This depends on how sensitive the person is to CBD, as well as the amount they ingest.
Because CBD supplements come in so many different forms—such as oils, gummies, tinctures, and vapors—the amount that’s actually absorbed can vary drastically. This, combined with each person, will ultimately affect which (if any) CBD side effects you might experience.
What Is Cannabidiol (CBD)?
CBD—the abbreviation for cannabidiol, a substance that’s generally derived from the hemp plant—has skyrocketed in popularity over the last five years. In fact, according to some research, “CBD” as a Google search term remained stable from 2004 to 2014 but has since ballooned by up to 605%.
CBD is one of the many chemical compounds that is found in the cannabis plant—referred to as cannabis sativa. There are two primary parts of the plant that humans use. One is THC, or Delta-9-Tetrahydrocannabinol, and the other is CBD. Though they’re from the same plant, THC and CBD are quite different from each other.
“CBD is not an intoxicating substance, whereas THC is a psychoactive that can get you high,” explains Dr. Jas Matharu-Daley, a physician and consultant for a brand that specializes in CBD production.
Are There Any Benefits Associated With Using CBD?
There are several reasons why someone might want to use CBD. The substance can be found in a multitude of products ranging from pain-relieving creams to edible tinctures to skincare. Research is still underway, but over the last few decades scientists have become more aware of how CBD might prove beneficial when applied either topically or ingested.
“Since discovering the endocannabinoid system (ECS) in the body in the 1990s, CBD has been researched more extensively. The ECS is a central regulatory system restoring normal balance and homeostasis in a range of human physiologic systems throughout the body and brain and has cannabinoid receptors and chemicals in its function,” explains Dr. Matharu-Daley.
CBD benefits include the following:
- CBD can have positive impact on the brain. In fact, Dr. Matharu-Daley says that the substance is legally prescribed in a specific medication for certain severe forms of epilepsy in children.
- It has also been shown to have anti-inflammatory properties, which is why you often see CBD in topical products such as oils, creams, and lotions.
- Some research points to CBD’s ability to relieve stress and anxiety.
- It has been used as a nausea treatment in some countries.
- CBD may potentially reduce pain symptoms.
- It has antioxidant properties, which means it can help fight off free radical damages that leads to premature aging.
- Regarding skincare, CBD may help reduce excessive oil production in those with very oily skin types.
Ultimately, the primary reasons why people use CBD is because it tends to have calming, relaxing, pain-reducing effects. It has been used to alleviate joint pain and nerve pain, reduce anxiety and stress, treat insomnia, improve migraines, and address nausea.
CBD Is Still an Unregulated Substance
It’s important to point out that CBD is not regulated by the FDA and therefore dosages might not be accurate. It’s also difficult to know what an appropriate dose is the first time you try a new product.
“If the CBD is from a reputable source and one that has been inspected by a third-party independent lab, the content of CBD is more reliable,” notes Dr. Matharu-Daley. “The CBD should be organically grown, free of pesticides and heavy metals, and not sourced in food which can affect absorption. Generally, CBD is safe and side effects are few at low doses.”
A Word From Verywell
CBD is technically an unregulated substance in the United States and therefore it ought to be used with caution. This is especially important for those taking additional medications and/or those with ongoing medical issues. That said, preliminary research on CBD and its benefits are promising in relation to helping with mild to moderate health concerns and it is generally considered a safe substance. Health professionals do not consider CBD a cure-all for serious medical issues, including cancer.
As with any sort of supplement, we recommend speaking to your medical doctor about whether using CBD makes sense for you. Your doctor can also recommend certain products that align with your needs and help ensure you get the correct dosage.
You have probably heard of the benefits surrounding CBD, but what are the potential side effects you ought to be aware of?
