What is Cotton Mouth From Weed?
Introduction
Cannabis consumption has grown in popularity, both for recreational and medicinal purposes. As more people engage with cannabis, one side effect often associated with its use becomes a frequent topic of discussion—cotton mouth, or xerostomia, as it is scientifically known. While not experienced by every user, cotton mouth is a common issue that can be uncomfortable and unpleasant. Understanding what causes cotton mouth, how to prevent it, and its long-term effects is important for any cannabis consumer.
This article explores the causes, symptoms, and solutions to cotton mouth, particularly in relation to THC consumption.
What is Cotton Mouth?
Cotton mouth, medically referred to as xerostomia, is characterized by a dry and sticky sensation in the mouth, resulting from decreased saliva production. The term "cotton mouth" is commonly used within the cannabis community to describe the arid feeling in the mouth after consuming cannabis. It is usually caused by THC (tetrahydrocannabinol), the psychoactive compound found in cannabis that binds to the body's CB1 receptors, thereby affecting various biological functions, including saliva production. This lack of moisture in the mouth leads to a variety of uncomfortable symptoms.
Why Does Weed Give You Cotton Mouth?
The relationship between THC and saliva production is the primary cause of cotton mouth. When THC enters the body, it binds to CB1 receptors located in the brain and central nervous system. These receptors influence a variety of processes, one of which is the regulation of saliva secretion. When THC binds to these receptors, it disrupts their normal function, leading to a decrease in the release of acetylcholine—a neurotransmitter that helps stimulate saliva production.
In particular, the submandibular gland, one of the major saliva-producing glands in the mouth, is affected. THC’s interaction with CB1 receptors reduces the amount of saliva released, causing the mouth to feel dry. It is important to note that this phenomenon can occur regardless of the method of consumption—whether through smoking, vaping, edibles, or even THC-infused gum. Additionally, research suggests that the higher the THC concentration and the lower the CBD (cannabidiol) content in the cannabis product, the more likely the consumer will experience cotton mouth.

Symptoms of Cotton Mouth
While cotton mouth itself may seem like a minor inconvenience, it can lead to a range of symptoms that affect one's overall well-being. Some of these symptoms are temporary, while others can persist if cotton mouth becomes a regular occurrence. Here are the primary symptoms associated with cotton mouth:
Persistent Dryness: This is the most common and noticeable symptom. Even after drinking water or using saliva substitutes, the mouth continues to feel dry.
Difficulty Chewing and Swallowing: Saliva plays a vital role in the process of chewing and swallowing by helping to break down food and ease its movement through the throat. A lack of saliva can make these activities uncomfortable or even painful.
Altered Taste: Without sufficient saliva, the ability to taste food and beverages can diminish. This can lead to an altered or dulled sense of taste, making meals less enjoyable.
Oral Health Issues: Saliva is crucial for maintaining oral health. It helps wash away food particles and neutralizes harmful acids in the mouth, reducing the risk of tooth decay and gum disease. Chronic dry mouth increases the likelihood of developing cavities, gum disease, bad breath, and mouth infections.
Other symptoms that may accompany cotton mouth include a burning sensation in the mouth, cracked lips, mouth sores, and throat dryness. Chronic dry mouth can also lead to recurrent infections in the mouth or throat if not addressed.
Is Cotton Mouth Dangerous?
In most cases, cotton mouth is more uncomfortable than dangerous. For occasional cannabis consumers, it is typically a temporary condition that subsides as the effects of THC wear off. However, for frequent users or those who experience prolonged bouts of dry mouth, the condition can lead to more serious oral health issues. Saliva serves as the body’s natural defense mechanism for the mouth, helping to cleanse it of harmful bacteria and acids that can cause tooth decay and gum disease.
Without sufficient saliva, the risk of developing oral infections and cavities increases. Prolonged dry mouth can also make it harder for the body to fight off disease-causing bacteria, potentially leading to complications if not properly managed. If dry mouth persists for more than a few hours after consuming cannabis or becomes a regular issue, it is advised to seek medical advice to prevent long-term damage to oral health.
How to Prevent Cotton Mouth
Fortunately, there are several steps cannabis consumers can take to minimize or prevent the effects of cotton mouth. While avoiding THC altogether is the most effective solution, it may not be feasible for everyone. Here are some tips that may help reduce or alleviate the symptoms of cotton mouth:
Stay Hydrated: Drinking plenty of water is crucial for reducing dry mouth. Aim to drink 8–12 cups (64–96 ounces) of water per day. Sipping water regularly, especially during meals, can help improve chewing and swallowing.
Chew Sugarless Gum or Candy: Chewing gum or sucking on hard candy, particularly sugar-free varieties, can stimulate saliva production. Opt for flavors like sour, citrus, cinnamon, or mint, which are often more effective at triggering saliva flow.
Limit Caffeine and Alcohol: Caffeine and alcohol are known to dehydrate the body, which can worsen the symptoms of dry mouth. Reducing or eliminating beverages like coffee, tea, soda, and alcohol can help improve saliva production.
Avoid Spicy and Salty Foods: Spicy or salty foods can exacerbate the burning sensation that often accompanies dry mouth. If you are prone to cotton mouth, try to avoid these types of food.
Use a Humidifier: A humidifier can help increase the moisture in the air, especially during sleep, which may help prevent dry mouth overnight.
Quit Smoking and Avoid Tobacco Products: Tobacco is a known cause of dry mouth, so quitting or reducing your use of tobacco products can help mitigate the effects of cotton mouth.
Consider CBD-Infused Products: Some consumers find relief by drinking CBD-infused water or using products like Flintts Mints, which stimulate saliva production.

Treating Cotton Mouth
If prevention methods do not fully address the symptoms, there are several treatment options that can help manage cotton mouth. In cases where dry mouth is caused by medications, a healthcare provider may recommend adjusting the dosage or switching to a different drug. For cannabis users, saliva substitutes or artificial saliva products are available, which can provide temporary relief.
Some consumers may also benefit from sipping on CBD-infused water, which provides hydration and may help alleviate dry mouth due to CBD’s lack of interference with saliva production. Over-the-counter mouth rinses and saliva stimulants are additional options that may be suggested by a healthcare professional.
How Long Does THC Affect Saliva Glands?
The duration of cotton mouth symptoms largely depends on the amount of THC consumed, the frequency of cannabis use, and individual metabolism. While the initial effects of dry mouth may subside after a few hours, studies show that THC can remain detectable in saliva for up to six hours after consumption. For frequent cannabis users, THC may be detectable in saliva for even longer periods. This prolonged presence of THC in the system can result in longer-lasting cotton mouth symptoms, even after the psychoactive effects have worn off.
Final Thoughts
Cotton mouth, though generally harmless, is an uncomfortable side effect of cannabis consumption that can lead to short- and long-term oral health issues if not properly managed. By understanding the causes and symptoms of cotton mouth, consumers can take proactive steps to minimize its effects. Staying hydrated, chewing sugarless gum, and avoiding dehydrating substances like caffeine and alcohol are just a few methods that can help alleviate dry mouth. If cotton mouth persists, seeking medical advice and exploring additional treatments may be necessary to protect oral health while continuing to enjoy cannabis responsibly.
