How Does Weed Help Nausea?

Nausea is a commonly experienced symptom that can be caused by several factors, such as motion sickness, medical conditions, or certain treatments like chemotherapy. It can significantly impact one’s life by affecting appetite and the overall quality of life. While there are medications to alleviate nausea, an increasingly popular alternative remedy is the use of marijuana.

Marijuana has been utilized for many centuries to treat ailments, and its potential to relieve nausea has garnered increased attention in recent years. This article explores the effectiveness of marijuana in alleviating nausea and the mechanisms behind its effects.

Understanding Nausea

Before delving into how marijuana aids in reducing nausea, it is important to have an understanding of what causes this sensation. Nausea often occurs due to signals sent from the brain’s center (the vomiting center) as a response to internal or external stimuli. These stimuli can include factors such as stress, specific foods or odors, hormonal changes (such as during pregnancy), digestive disorders, infections, medications, or emotional influences. The brain and stomach collaborate closely in regulating digestion and maintaining balance within the body.

The Endocannabinoid System

To comprehend how marijuana effectively addresses nausea, it is essential to grasp the functioning of the endocannabinoid system (ECS). The human body has a network of receptors known as CB1 and CB2 receptors. These receptors are spread throughout the body and play critical roles in regulating important functions, such as controlling appetite, managing mood, and modulating the response to pain and inflammation. When cannabinoids like THC (tetrahydrocannabinol) found in marijuana plants activate these receptors, they interact with neurotransmitters in our system to produce various effects on the body. One significant effect of THC is its ability to alleviate symptoms like nausea, anxiety, and pain by activating these receptors. This can have an impact on our responses throughout the body due to communication between these receptors.

Using Marijuana for Nausea Relief and Appetite

Studies have demonstrated that specific compounds present in marijuana, THC, and CBD (cannabidiol) effectively alleviate symptoms of nausea. THC activates the CB1 receptors located in the brain’s vomiting center, thereby regulating the neurotransmitters involved in vomiting and nausea. In addition to reducing nausea, marijuana is also known for its documented ability to stimulate appetite. Individuals undergoing chemotherapy or living with conditions like HIV/AIDS often experience a loss of appetite, leading to weight loss. Marijuana has been found to increase appetite by stimulating areas of the brain associated with hunger and satiety, helping individuals regain some much-needed nutrition.

Benefits of Marijuana for Specific Medical Conditions

There are certain conditions that can cause chronic or prolonged episodes of nausea. Marijuana can offer benefits to individuals who are experiencing the following symptoms:

  • Nausea and Vomiting due to Chemotherapy: The antiemetic properties of marijuana make it a valuable treatment option for cancer patients dealing with complications related to chemotherapy, such as nausea and vomiting.
  • Gastrointestinal Disorders: Conditions like Crohn’s disease, ulcerative colitis, and irritable bowel syndrome can cause several symptoms, including intense nausea. Marijuana may help alleviate these symptoms through its inflammatory and pain-relieving properties.

The ability of marijuana to combat nausea is primarily attributed to its impact on the neurotransmitter signals involved in causing vomiting. Many recent research findings also support this theory.

Side Effects & Considerations

While marijuana can effectively alleviate nausea in most cases, it is important to consider side effects and legal restrictions. Some possible side effects of using marijuana include dizziness, dry mouth, increased heart rate, impaired coordination, and short-term memory loss. Furthermore, the regulations concerning the use of recreational marijuana differ significantly depending on the jurisdiction. It is essential to seek advice from healthcare professionals with expertise in cannabis treatment to ensure appropriate usage.


Marijuana has shown significant potential as a remedy for relieving nausea. Its ability to activate receptors in the system and regulate neurotransmitters involved in vomiting makes it an effective solution for alleviating nausea symptoms. However, it is crucial to consider its side effects as well and consult healthcare professionals before incorporating marijuana into a treatment plan. As ongoing research continues to deepen our understanding of cannabis therapy, we will gain insights into how marijuana can combat specific symptoms like nausea. This constant evolution in knowledge regarding the properties of this plant offers hope for individuals experiencing chronic or treatment-induced nausea who may find relief through its use.
