What are the side effects of CBD?

If CBD is known for its relaxing properties, we wonder if there are any CBD side effects . Response elements.

The 3 side effects of hemp

Like other substances, CBD can have undesirable effects on the body. The most reported effects include dry mouth, loss of appetite and diarrhea.

Dry mouth

Having a dry, pasty, sticky mouth is a familiar feeling for smokers of THC-based narcotics. This unpleasant effect also occurs when consuming CBD, although it is not psychotropic. This dry mouth is explained by the action of cannabidiol on the endocannabinoid system , and in particular on the receptors present in the salivary glands. It appears that this molecule blocks the action of these receptors, thus reducing the natural secretion of saliva. However, it is possible to remedy this feeling by drinking a glass of water.

Reduction of appetite

Unlike tetrahydrocannabinol which makes you hungry, cannabidiol reduces appetite. On the one hand, CBD stimulates the body's production of serotonin. By increasing the level of this happiness hormone, CBD helps improve mood. However, high levels of serotonin act on the nervous system to give a feeling of fullness, thus reducing appetite. On the other hand, cannabidiol improves the circulation of anandamide by preventing its degradation. It is a cannabinoid produced by the human body which also intervenes in the regulation of appetite by modulating hunger.

Although this CBD side effect is beneficial for people who want to lose weight, it can be bothersome for others.


CBD side effects can be seen in the digestive system. Indeed, when consumed in high doses, cannabidiol could cause diarrhea or constipation problems. In this case, it is necessary to reduce the dosage of the product and reduce the frequency of consumption. If the problem persists, it is better to consult a doctor to find out if the patient has an intolerance to CBD. Because, although most consumers respond well to cannabidiol, some people may not tolerate it.

But it is also possible that the side effects are due to poor quality of the product. It is therefore recommended to only purchase CBD oils from a manufacturer that meets production standards.

Consumption of CBD as a contraindication

CBD can interact with medications. It may affect the effectiveness of the treatment. To avoid harmful interactions, it is best to seek the advice of a doctor before taking cannabidiol products.

Furthermore, the consumption of CBD is not recommended during pregnancy. Just as a pregnant woman must stop drinking alcohol and smoking, she must also stop using cannabis. Indeed, even if the amount of THC contained in cannabidiol products is tiny, it can be toxic to the fetus. Likewise, taking CBD is not recommended while breastfeeding due to the lack of study on the passage of this substance into breast milk. It is therefore preferable to be patient to avoid side effects .

Generally speaking, CBD should not be used as part of self-medication. It must be prescribed by a doctor or pharmacist to respect the dosage and avoid CBD side effects .

Summary: points to remember about the negative effects of CBD

In short, the negative CBD effects are few in number and generally last for a short period of time. The best known effects are:

  • the feeling of dry mouth, caused by the blocking of the action of endocannabinoid receptors present in the salivary glands;
