What is cottonmouth from weed?

The medical term for cottonmouth is Xerostomia or hyposalivation, which means a lack of saliva flow. Many things can trigger this condition, including illness, medications, and consuming certain products like cannabis. 

Saliva is more importantthan just keeping our mouths wet and indicating when we need to rehydrate. The liquid also contains electrolytes, enzymes, and antibacterial properties crucial for breaking down food. It plays a vital role in our oral health, keeping teeth strong and gums clean. 

When marijuana dry mouth hits, these processes are compromised, leading to more severe issues with our health if left untreated. 

The term cottonmouth refers to the feeling it causes in the mouth and throat. Signs that you’re suffering from weed dry mouth include: 

  • Dry or claggy feeling in the mouth.
  • Sore and tickly throat.
  • Stringy saliva. 
  • Insatiable thirst. 
  • Split skin in the corner of the mouth or on lips.
  • Difficulty talking and swallowing.
  • Your tongue sticks to the roof of your mouth.
  • Denture wearers may find it a challenge to insert their teeth comfortably. 

Is cottonmouth dangerous to health? 

Mild and occasional cases of cottonmouth from weed aren’t anything to run to your physician about. Typically symptoms only last a maximum of a few hours after you put the pot down. 

If severe symptoms of hyposalivationplague your marijuana sessions, then you could be facing a chronic problem that can trigger a number of oral health problems such as:

  • Gum disease: A lack of saliva makes the gums more susceptible to plaque, tartar, and bacteria buildup, which can cause gum disease. Without proper treatment, teeth loosen and fall out. `
  • Damage to teeth: When the mouth is dry, plaque builds up much faster. Without adequate saliva, foodand acids get stuck between teeth causing them to rot. 
  • Enamel erosion: Saliva also neutralizes any acidity in the mouth. Without it, too much acid erodes the tooth enamel, and your mouth will be prone to infection. 
  • Staining: Your saliva acts as a cleaning fluidas it passes by your teeth. When the flow is inefficient, discoloration and stains appear

Why does weed give you cottonmouth?

Many people are under the misconception that weed smoke is the cause of cottonmouth. The real answer to why does weed make your mouth dry is a lot more complex. 

Recent research has found that it’s actually triggered by how the cannabinoid THC in weedinteracts with our endocannabinoid system

To learn why you get cotton mouth after smoking weed, first, you must understand how the system works. It consists of a network of cannabinoid receptorsthat are found throughout the body and brain.

The cannabinoids in marijuana activate these receptors. Famously these interactions give you that high feeling, but they also affect the body in many other ways. 

One of which is the production of saliva from the submandibular gland. It’s responsible for producing the largest amount of saliva in the mouth. 

It’s thought that when THC binds with the submandibular glands’ cannabinoid receptors, it causes them to stop receiving messages from the nervous system to produce saliva. As a result, the decreased secretion leads to Xerostomia.

Do edibles cause dry mouth?

Now we know the answer to why does weed give you cottonmouth? With this in mind, it’s easy to understand that not only does smoking cause dry mouth but any THC product you consume. 

Do edibles cause dry mouth? Yes, edibles and vapes also interact at some level with your endocannabinoid system and, therefore, can trigger dry mouth symptoms.

How to get rid of dry mouth when high?

Experiencing dry mouth after smoking weed can put a negative spin on the experience and dampen your high. Some users even blame cottonmouth from weed for triggering bouts of paranoia. 

Don’t let it ruin a session with your favorite strain or become a chronic condition. Take action to relieve the issue. 

Learn how to get rid of dry mouth when high below. We’ve put together some simple and inexpensive remedies for you to turn to when your tongue gets stuck to the roof of your mouth. 

Stay hydrated

The number one piece of advice on how to not get cotton mouth when smoking weed is to stay hydrated

Keep a bottle of water handy while you enjoy your joint or edible. Take small sips but often, ideally through a straw. Drinking large amounts of water at once can aggravate the issue and cause dryness as it washes away the mucus film that lines the mouth. 


Dentists commonly prescribe fluoride-based mouthwashes and toothpaste to patients suffering from dry mouth. These products increase saliva production, promote oral hygiene, and prevent the long-term damage cottonmouth from weed can cause. 

Eat some candy

As well as a yummy treat, eating candy or chewing on some gum stimulates the salivary glands. The action encourages them to make more liquid so that your food enjoys a smooth passage into the stomach. 

Research has also found that the saliva produced from masticatory stimulation contains an increased amount of ions. They work to relieve the symptoms of cottonmouth from weed and play a part in remineralizing tooth enamel. 

Breathe through your nose

If you feel marijuana dry mouth setting in, breathe deeply through your nose. When you draw air in through your mouth, it dries the area out and interferes with saliva creation. 

In comparison, breathing through the nose adds moisture preventing your mouth from drying out and becoming scratchy. 

Cough medicines 

Cough medicines like syrups and drops are an ideal remedy for cottonmouth; they coat the mucous membrane of the mouth with a soothing film of liquid. 

They work much faster than chewing on candy but remember to follow the recommended dosage to avoid overdosing. 

Use a humidifier

Regular marijuana users stop dry mouth after smoking weed by using a humidifier in their homes. Most modern homes are full of dry ambient air, which is known to worsen mouth and throat dryness. 

For optimal health and comfort, keep the humidity in your house in the 30–50% range

How to prevent dry mouth when smoking weed?

As with anything negative in life, prevention is always better than the cure, and the same is true for cottonmouth from weed. 

THC interacting with the endocannabinoid system is to blame for the condition. It’s impossible to tell how the cannabinoid will affect you each time. You should know if you’re going to consume marijuana, then dry mouth can’t be completely avoided.

Read on to learn how to prevent dry mouth when smoking weed to the best of your ability. Following the below lifestyle choice changes can keep your mouth, throat, and saliva production in tip-top shape, helping to mitigate symptoms and reduce the risk of chronic hyposalivation. 

Avoid alcohol

Alcohol has diuretic properties, which means it removes water from your blood. As a result, it can dehydrate you very fast and cause a dry mouth. It also irritates any mucus present in your mouth and makes gums much more susceptible to inflammation. 

Run from caffeine

Soda, coffee, tea, and any other caffeinated drinks significantly reduce saliva production and trigger cottonmouth. Studies suggest this is because the compound compromises adrenergic modulation in the body. The regulatory mechanism is responsible for blood pressure. 

Do not smoke cigarettes

Smoking tobacco products hinders saliva creation, which in turn aggravates a dry mouth.

A cigarette smoker’s mucus secretionsare also typically muchthicker than they should be, making the salivaineffective in supporting good oral health. 

Avoid dry snacks

The sharp edges of dry snacks like chips and crackers can easily damage the soft tissue of your inner cheeks, irritating the mouth and compromising the mucous lining

Most of these products are also covered in salt, which dehydrates the body and dries out your mouth.

What causes cottonmouth?

THC interacts with the endocannabinoid system and binds to receptors through the body, including those found in the largest salivary gland in the mouth.

What drinks help cottonmouth?

Water is the best choice when you’re trying to get rid of weed dry mouth. Small and frequent sips lubricate the mouth and keep you hydrated. 

If water isn’t your thing, then herbal teas are another great option. They’ll help to soothe the symptoms and keep your water levels topped up. Avoid caffeinated products as these only worsen the cottonmouth.

What foods increase saliva production?

Many everyday food products help reduce the symptoms of cottonmouth from weed by promoting saliva production. 

Xylitol, for instance, highly stimulates the nervous system responsible for saliva flow. It’s a natural compound found in various products, including berries, oats, peanut butter, and chewing gum

Sugar-free lollipops, lozenges, and mints are also great salivary stimulants. Like chewing on your favorite candies, these items encourage your glands to bump up production while also lasting long enough to soothe the symptoms.
