Why Cannabis Causes Excessive Burping and Tips to Prevent It

Why Does Weed Make You Burp? The Link Between Cannabis and GERD

It's common to get the burps after smoking or ingesting cannabis. But what causes weed burps, and are they something to be concerned about? Here's a look at the connection between marijuana use and burping, including the role of cannabinoids and their effect on gastroesophageal reflux disease (GERD).

Can Cannabis Cause Excessive Burping?

Burping, or belching, is the act of expelling gas from the upper digestive tract through the mouth. It's a normal bodily function that helps release air that is swallowed during eating and drinking.

However, smoking or ingesting cannabis can lead to more frequent and intense burping spells. This is due to the impact of cannabinoids like THC and CBD on the lower esophageal sphincter (LES).

The Role of the Lower Esophageal Sphincter

The LES is a ring of muscle that separates the esophagus from the stomach. It acts as a valve that opens to allow food and liquid to pass into the stomach, and then closes to prevent the contents of the stomach from moving back up into the esophagus.

When the LES relaxes too frequently or for too long, stomach acid can rise up into the esophagus. This is known medically as acid reflux or gastroesophageal reflux disease (GERD).

How Cannabis Affects the Lower Esophageal Sphincter

Research shows that cannabis use can interfere with the functioning of the LES by causing it to relax. Studies have found that THC, the primary psychoactive compound in cannabis, activates CB1 receptors in the LES.^[1] This receptor activation signals the LES to relax, allowing increased reflux.

CBD has also been found to influence lower esophageal sphincter relaxation through its interaction with the endocannabinoid system.^[2]

Frequent reflux of stomach contents caused by cannabis use can lead to burping as the body's attempt to release excess gas produced by stomach acid rising into the esophagus.

Other Factors That Can Contribute to Cannabis-Related Reflux

While the effect of cannabinoids on the LES is the primary cause of weed burps, other factors can also be at play:

• The mode of ingestion - Smoking and vaping can promote air swallowing and gastritis.
• The terpene content - Some terpenes may relax smooth muscle tissue in the GI tract.
• Strain type and potency - High THC strains may have a greater impact on the LES.
• Dosage - Higher doses further activate CB1 receptors.
• Method of ingestion - Edibles delay activation of cannabinoid receptors.
• Obesity - Excess weight increases intra-abdominal pressure.
• Hiatal hernia - Compromises the LES valve.
• Pregnancy - Hormonal changes that can weaken the LES.

Managing Cannabis-Related Reflux and Burping

If you frequently experience burping after using cannabis, there are some things you can try to minimize reflux:

Choose Low-THC Strains

Opting for strains lower in THC may reduce the effect on the LES. Strains with a more balanced ratio of THC to CBD may also help alleviate burping.

Ingest CBD Separately

Taking CBD on its own, away from THC-containing products, could reduce burping. However, CBD-only products can still potentially relax the LES.

Change Forms of Ingestion

Substituting smoking and vaping with other methods like edibles, tinctures, or topicals could lessen the impact on the LES. This avoids irritating the esophagus with hot smoke.

Manage Dosage and Timing

Lower doses spread out over time rather than large single doses can minimize reflux events. Allowing sufficient time between doses gives the LES time to recover.

Avoid Certain Foods and Drinks

Greasy, spicy, or acidic foods and drinks can make reflux worse when combined with cannabis. Avoid trigger foods around the time of use.

Improve Posture

Remaining upright after ingesting cannabis can use gravity to keep reflux in check. Reclining too soon can make symptoms worse.

Wear Looser Clothing

Tight clothes put extra pressure on the abdomen and can promote reflux. Wear loose, comfortable clothing when ingesting cannabis.

Lose Weight If Overweight

Excess weight strains the LES valve and increases intra-abdominal pressure. Losing weight can alleviate reflux issues.

When to See a Doctor for Cannabis-Induced Reflux

Frequent, bothersome reflux that persists despite lifestyle changes warrants a discussion with your doctor. Seek medical advice if you experience:

• Burping multiple times per day
• A sour, bitter taste in the mouth
• Burning sensation in the chest, known as heartburn
• Regurgitation of food or liquids
• Feeling of a lump in the throat
• Chronic cough, hoarseness, or sore throat
• Tooth erosion from excessive exposure to stomach acids

A physician can help determine if GERD is present and recommend treatment options, which may include:

• Prescription strength acid-blocking medications
• Over-the-counter antacids
• H2 blockers to reduce stomach acid
• Proton pump inhibitors to prevent acid production
• Surgery if GERD is severe

In some cases, stopping cannabis use may be required to resolve severe GERD symptoms. Otherwise, the management tips above can help minimize burping episodes.

The Bottom Line

Mild to moderate burping is common when ingesting cannabis due to the relaxing effect of THC and CBD on the lower esophageal sphincter. While benign for most, frequent reflux can indicate underlying GERD requiring medical attention.

Adjusting consumption methods, dosages, diet, and posture can help reduce burping from cannabis use. See a doctor if lifestyle changes do not resolve bothersome reflux symptoms.
