Does CBD Help You Poop? The Science Explained

Cannabidiol (CBD) is a compound harvested from the Cannabis sativa plant, widely recognized for its potential wellness benefits. Unlike its close relative, THC, CBD is non-intoxicating, meaning it does not produce the “high” associated with cannabis use. A growing number of people are exploring its use for digestive health, leading to the question of whether CBD can scientifically assist in regulating bowel movements and addressing constipation.

CBD and the Gut’s Endocannabinoid System

The body contains a complex regulatory network known as the Endocannabinoid System (ECS), which plays a significant role in maintaining balance across multiple physiological systems. The ECS is distributed throughout the body, including the gastrointestinal tract, where it helps regulate functions like sensation, inflammation, and motility. Within the gut, the ECS interacts closely with the Enteric Nervous System, which controls muscle contractions and fluid balance.

CBD is thought to exert its effects on digestion by modulating the activity of this system. CB1 receptors are found in the neurons of the enteric nervous system, regulating muscle contractions, while CB2 receptors are more common in immune cells and modulate inflammatory responses. By influencing these receptors and other non-cannabinoid targets, CBD can indirectly affect the overall environment of the gut.

Impact on Bowel Motility and Constipation

The question of whether CBD helps a person “poop” is directly related to its influence on bowel motility, the process of muscle contractions that moves waste through the intestines. Preliminary animal studies have suggested that cannabinoids, including CBD, may modulate intestinal muscle contractions. This modulation can potentially increase or decrease the speed of movement through the digestive tract depending on the specific dose and individual response.

Some evidence suggests CBD may help relieve constipation, but this benefit is often viewed as indirect. Chronic stress and anxiety are known contributors to digestive issues by causing tension in the gut, and CBD’s noted anti-anxiety effects may help relax this digestive tension. Furthermore, by interacting with receptors like CB2 and PPAR-γ, CBD may help reduce inflammation in the gut, which can be a secondary factor in some forms of constipation.

The current scientific data is limited, with a scarcity of large-scale human trials specifically investigating CBD as a treatment for constipation. While some people report positive changes in regularity after using CBD, the evidence supporting it as a direct prokinetic agent remains preliminary. Therefore, any use for this purpose is based largely on anecdotal reports and the broader understanding of the ECS’s role in gut regulation.

Dosage Considerations and Digestive Side Effects

There is no standardized, clinically approved dosage for individuals considering using CBD for digestive issues. A common recommendation is to start with a low amount, such as 10 to 20 milligrams per day, and slowly increase the dose while carefully monitoring the body’s reaction. This approach allows the individual to find the minimum effective dose and reduce the risk of adverse effects.

A notable side effect of CBD use, especially at higher doses, is diarrhea or loose stools. This digestive discomfort is often attributed not just to the CBD itself, but also to the carrier oil used in many tinctures, such as MCT or hemp seed oil, which can have a laxative effect. Digestive issues like diarrhea are a frequent reason for people to discontinue CBD use, highlighting the importance of cautious, low-dose initiation.

CBD can interact with several common medications by affecting liver enzymes responsible for drug metabolism, similar to the “grapefruit warning.” Consulting a healthcare provider is prudent before beginning a CBD regimen, particularly for those who take prescription drugs or have existing digestive conditions. Choosing a high-quality product with a Certificate of Analysis ensures purity and minimizes the risk of consuming irritants that could upset the gastrointestinal tract.
